Dr. V under a microscope!


This very long web page has a full description of my professional history, including some of the most valuable results of my work.


But in short: I’m a very experienced teacher with about thirty years of teaching math and physics – in different countries, to different students: from 5-th graders to high school students, to college and university students, to schoolteachers and students with some intellectual deficiency. I have M.S. in Theoretical Physics, PhD in Education. And I love teaching in a remote format, so if you are looking for a part-time remote instructor, please give me a shout via teachology@teachology.xyz.

In the past, in addition to teaching, I was providing
consulting services to teachers and administrators; I was a director of an institution for policy analysis and development and a member of a group implementing on a large scale Socratic approach to teaching. After moving to Boston I mostly just teach.
I teach my students
how to use their brain for designing solutions to problems they have never solved before (i.e. be truly intelligent). Any problems, not just in physics, because the process of designing a solution is universal (unless, of course, instead of a brain someone uses a different organ).

Many people write what they think about education.  I write what I know about it - as a professional and an expert in the field.

The other day (in 2020) I was called in a hallway “Mr. V, hi, do you still teach physics?”

That was one of my students from three or four years ago.

We had a brief conversation.

“Of course, I do, I love it!”

“Mr. V, you were the best physics teacher I had”.

“Thank you.”

“And everyone tells that you are the best”.

“Well, I know that some students do not like me”.

“I don’t care what people say on the Internet. All my friends say only good things about you”

“Thank you, I had very good teachers, and I just try to do what I learned from them”.

To read more from my student evaluations, please, follow to
the Voice of my students.

I believe the following ten pages (more than ten years of teaching!) of good words of what my former students have said about me, represent me better than any official Resume (but this page also provides my Resume and standard CV).

The main reason for representing student feedback is to demonstrate that when I talk about education, I know what I’m talking about; and I know this not just because of books I’ve read, or my theorizing on the matter. I know this because of books I’ve read, because of my own theorizing on the matter, but most importantly because of my own deep, broad, and successful (at least, according to me students) teaching experience. 

I know teaching, because I do teaching, and I am good at it; it took time to become a good teacher; I am good at it because I have been constantly
analyzing my teaching practice and making it better.

With best regards,

Dr. Valentin Voroshilov

Voices of My Students (and this is a
link to copies of some past evaluations).

I started this collection in 2008 and stopped adding new entries in 2020 (the entries are not in a chronological order).

“Professor V. is extremely passionate about physics, which made this course more enjoyable. Despite the technological difficulties that occurred during this summer term, Professor V. was able to manage the obstacles thrown at him, and execute teaching a difficult course remotely. In addition, the coursework was extremely beneficial in terms of preparing for the exams, and I never felt lost during the course.”

“Prof. Voroshilov, I’m at a loss for words to express my gratitude. In all of my years of school, from elementary, into high school, and through college, I have been blessed with top-notch teachers. But I’m pretty sure you take the cake. I was originally debating between taking physics at Harvard or BU, and all the signs pointed to BU. Honestly, I kind of think it was fate. I am not sure if it was just a good student – teacher match, but I thoroughly enjoined your lectures. You have an uncanny ability to present material, and it’s pretty clear (to me, at least) how much effort you put into your work as a teacher.”

“Thank you, thank you, thank you! Mr. V, thank you for putting up with all of us this summer!! I feel much more prepared for the MCAT. And I loved the demonstrations! Thanks for putting all the time + effort!”

“Professor V, You designed this class so that those who put in the effort would succeed, so I gave it my all and sure enough."

I want to say thank you for creating such a conducive learning environment for me to succeed. I hadn't taken a physics class since my freshman year in high school, so I was very nervous going into your class. I did not expect this course to become my favorite science course so far at BU. Physics is a hard subject, but you explained everything well and made sure we, as a class, had the tools necessary to succeed with enough hard work on our end.”

“Professor Voroshilov is great – he explains concepts very well, and makes great use of clicker questions, demos, etc. Prof. Voroshilov also uses powerpoint, transparencies, videos, cameras, tablets, etc. very creatively and effectively to reinforce material from lecture.”

“I didn’t like physics before taking this class and now it’s one of my favorite classes.”

"I hated physics before taking this course, and now after taking both 105 and 106 with Mr. V, I actually really enjoy it. He is one of the best teachers I've ever had. Thank you"

“Best physics professor here, only one who cares if students are learning the material. Proves you don’t need a PhD in physics to teach this class. PhD in education is much more effective.”

“Needs to teach the fall/spring semester! Physics makes so much sense!!!”

“He is awesome! Clear when he presents, fun demos, good sense of humor Used real life examples to represent difficult to learn concepts, made class fun he is enthusiastic and experienced.”

“Mr. V's enthusiasm and passion for what he does was clearly reflected in his teaching. By doing a lot of demonstrations and connecting theory to real-life examples he made the material much easier to understand.”

“Makes concept sound simple.”

“I found that Professor V. was a fantastic professor to have! In particular, I appreciate that he put time into ensuring the online nature of the course was not a detriment to our lives, particularly as I work outside school. He hardly ever stumbled in the use of technology to provide us with the best in-class experience.”

“Professor V. has a strong passion and drive for teaching physics.”

“He worked hard to make sure the technology worked in a timely and organized fashion.”

“Professor V. is extremely passionate about physics allowing for this course to be more interesting than normal. His teaching style and presentations are straightforward, and allow for the material to be mastered as long as you work hard for it.”

“I loved Professor V. because he was never trying to trick students, and he truly hopes all students can be successful in PY105.”

“There are clear explanations for every single problem we encountered, alongside theoretical background of all derivations and processes studied. The instructor also appears enthusiastic, which is very helpful for courses like physics (easily monotonous with all the math involved)”

“He uses lot's of models and examples to teach.”

“He is very caring and thorough, tries to be clear with his expectations. We really appreciate how much time and effort he puts into his lectures, demonstrations, and the amount of his own time he puts into answering piazza questions. I have never had a professor who cares enough to answer piazza questions as often as Mr. V so I commend how much effort he puts in”

“I was at first a bit scared of Dr. V because of his extremely confident way of talking and how he occasionally comments students directly. However, I started to enjoy his class more and more, and now I find him to be an incredibly smart and entertaining professor. He knows how to keep one's attention. Moreover, he is extremely organized and doesn't waste time on anything, forcing students to pay attention at all time. Finally I love when he makes some small political comments.”

“Professor V is excellent, I have no complaints. He is enthusiastic and caring, as well as extremely knowledgeable. He was passionate and available regularly for help.”

“He is really funny without trying too hard. He's definitely one of my favorite personalities of the university professors I've had so far. I feel like every ruling he had regarding our class was fair, sometimes even too nice. I felt this class more than any other I have taken at this school benefited me. I spent a considerable amount of time preparing for the exams, and wasn't surprised by a single question on them. He really, really cared about the students, even if he didn't express it explicitly. He came off cold at first, especially in the responses he'd give to students on Piazza who were not doing well in the class. It was in his actions that I really noticed he cared, like spending days regrading exams after there were discrepancies, or changing the format of labs due to technical difficulties on the student's parts. A teacher who didn't care wouldn't have changed those things.”
“He was comfortable with the technology which made everything easier on our end as students. He was able to adapt quickly when things went wrong such as Echo360 shutting down, etc.”

“Dr. V is a very passionate instructor. His presentations are straightforward and cover a lot of problems. The questions are engaging and the experiments are interesting. Lots of great demonstrations”

“Great energy, the lecture is really easy to understand.”

“If I could give a 10 for Dr. Voroshilov, I would. Excellent teacher. Makes physics fun (which is a very hard thing).

“I love Mr. V.”

“Dr. V is a great professor. Cares about physics and his students.”

“Loved Dr. V. Wish he taught during the school year as well.”

“Fantastic teacher.”

“Make you work if you want to do well.”

“It’s a generally really cool course.”

“Mr. V was by far the best professor I have ever had at BU. I wish he taught through the school year. He is always enthusiastic, explains topics well, and has great models. I don’t think any other science teacher at BU can match up to him.”

“Fantastic instructor. My favorite science professor I’ve ever had. Amazing at making even the most difficult or boring subjects interesting and fun. Absolutely hilarious. Won’t take physics if not with him. Just needs neater handwriting.”

“He is a master. He knows his material. He wants to help. That’s all I can expect from a teacher. He is great.”

“He tends to challenge us by truly assessing which of my aspects are flawed.”

“He’s great. One of the best instructors I’ve had at BU.”

“He really makes the class enjoyable.”

“Professor V is an excellent professor and by far my favorite I have had in my three years at BU. It would be a delight to have him teaching here during the school year as well.”

“He is a master. I think all professor should be able to teach as him. That way students would not have to spend hours reading off of lectures.”

“I can honestly say I had never seen a professor who cared more for his students and how they do, as well as what they learn.”

“Best teacher I’ve had, bar none.”

“Explains things in a way that can be understood – explains why we care. Great and interesting demos. One of the best science professors I’ve had at BU. Actually wants us to do well. Lear expectations.”

“Val was a breath of fresh air after CH109 and 110. Great lecturer; I almost became a physics major because of Val (and the TFs, too). Explains well, is nice, has great presentation.”

“Incredible instructor; best one I’ve ever had at BU. He above puts the chemistry department to shame in how thorough and passionate his lectures are. I would change to a physics major or minor if he taught every class.”

“The examples were very thorough and thought-provoking. The demos were interesting and made of material more applicable to real-life scenarios.”

“Punctual, respectful of class end-time (much appreciated). Extremely knowledgeable about content, very effective at braking things down to digestive pieces, and presenting it in a logical, glowing manner. Highly engaging demonstrations. Great use of tools/props. Good energy (especially for a 9 am class). Professor Voroshilov has a very matter-of-fact/this-is-so obvious aspect to some of his statements, which I personally like, but could be discouraging to some students. If that’s just his personality, then I’m not saying he should change it, just be mindful of how others might perceive it.”

Honestly, he is one of the best professors here in BU. He's engaging, loves teaching the material, and helps the students out to understand the concepts.

“Very passionate, good at explaining topics and going through enough example problems, experiments/demonstrations performed in lecture were helpful.”

“I love you Mr. V, you make physics bearable!”

“Fair and quick grader. Has a really funny and dry sense of humor. Felt prepared for tests.”

“The professor is very enthusiastic and has a lot of experiments relating to the topics we're learning.”

“Professor V. presents himself as somewhat cold and calculating, and appears to not care for his students. This is the first impression most people get, likely due to the nature of the material not involving emotional response. In reality, Professor V. cares deeply for his students, and it is apparent when he spends the time to answer students questions, regardless of how complicated or simple it may be. Professor V's teaching style keeps you motivated and engaged, and his presentations are clear and direct.”

“I have always dreaded taking Physics — so much that I waited until the summer after I had completed all the other undergraduate requirements and still hadn't taken it. I am very glad I waited and had Mr. V as a professor; he knows the material extremely well and teaches it clearly and explains well. One of my favorite professors thus far.”

“Mr. V has the most extraordinary way of teaching a topic that most people fear. His sense of humor keeps the class amusing. I'm happy that my physics experience was left in the hands of such a passionate and instructor. The course always felt fair and prepared us for his expectations.”

“Amazing professor. Waited for the summer so I could take PY105 and PY106 with him. Funny in his way and very fair. Always helpful. Would only take this class with him.”

“I think he is very relatable and very funny. I think he genuinely wants people who are willing to work to do well. He is very fair with his grading policy. Many students who complain about him are just taking advantage of him to begin with, and are being unfair to him.”

“The professor explains the concepts very well although of the language barrier, and he tries his hardest for students to understand, he grades the exams fairly.”

“Prof. Voroshilov is very good at what he teaches, his slides are dense and helpful. Prof. Voroshilov is entertaining and teaches well. Prof. Voroshilov is awesome!”

“Prof. Voroshilov is always extremely prepared for lectures. Excellent lecture slides, demos and PRS questions, online class site and resources are excellent and helpful.”

“I appreciated your sarcasm and the way you were teaching us to be very specific with our question because this helped me to become better with my analytical skills.”

“Very enthusiastic and approachable. Genuinely cares about his students. Best professor at BU.”

“Thank you for making physics so much fun, and for being such an awesome teacher! Happy teachers’ day! You were definitely my favorite teacher! You always made our class very entertaining and I was really lucky to have you as a teacher! Thank you for teaching me to check my grades! Have a wonderful summer and stay in touch, I will read your book and tell you what I think!”

“He really cares about his students and provides the appropriate materials for their success.”

“Good instructor. Helps students learn well.”

“Good at breaking things down.”

“Passionate about teaching.”

“Very funny. Genuinely interested in the best ways to teach material.”

“Mr. Voroshilov has a clear understanding of all he teaches and is a master on the subject.”

“Mr. Voroshilov does a good job of doing example problems with a simple approach to make material clear.”

“Enthusiastic and entertaining.”

“I really liked him. One of the best instructors at BU. He explained concepts very well, his exams were pretty straightforward and based off homework. He is really fair. He uses equipment’s to explain the concepts which makes it fun.”

“He is an amazing professor and goes into depth about the material.”

“I love his lecture style! It is so helpful that he does many example problems during class.”

“Dr. V explains concepts extremely well; I am very rarely confused and if I am it is often cleared up very quickly. He also is quite funny, making class engaging and more entertaining (especially since it is such an early class).”

“Mr. V clearly knows where students are more likely to be tripped off, and thus reminds us in lecture to not make certain mistakes. He also explains concepts in multiple ways to make sure students understand each theory.”

“-hilarious, kept lecture entertaining -demos prevent you from falling asleep -always willing to answer questions -really cares about students”

“Prof. Voroshilov is a great teacher, very wise and clear. All exams have been extremely fair so far, and he has done a great job at conveying the material. I now have developed a much greater interest and understanding of the beauty of physics. I look forward to PY106!”

“I enjoyed lecture he clearly cared about the class and was straight forward.”

“He really explains things very well, and does plenty of sample problems. The sample problems really further the understanding of the course material.”

“Really enjoyed the dry humor. At first, I found it a bit too much but as time went on I like it more and more. Exercises in class are helpful.”

“Gives very fair exams.”

“Great explanation of concepts.”

“Very enthusiastic. Used lots of demonstrations. Always made time for questions.”

“Gives many question examples. Each lecture has many helpful visuals.”

“Very funny in some way. Goes over the course concepts clearly.”

“Fantastic. Love his humor, makes class fun. Tons of office hour availability which is great. Very good at explaining concepts.”

“Incredibly funny and encouraging. Really enjoyed the class.”

“Very clear and knowledgeable. Funny. Made class fun and attainable.”

“Cares about students. Jokes around with them.”

“Fantastic teacher. I suck at physics and Mr. Voroshilov made it very straightforward, understandable and manageable. Also hilarious.”

“Mr. Voroshilov has a teaching technique that is almost flawless, and I wish more professors had the ability to make a class as lively and interesting as Mr. Voroshilov has done this summer. He was literally ready to risk his life to show us demonstrations, solved as many problems as he possibly could, and was fair in exams. Way to go, wish more professors were like you. Very intelligent, knows material very well.”

“Makes the class entertaining. I find physics to be boring at times but he keeps things fun. Very fair grader and I like his tests.”

“He is clearly passionate about physics. His accent is not a problem, because he genuinely tries to speak slowly and clearly. His class demonstrations are really helpful.”

“Very smart and very funny. Physics is hard but Val made the experience more enjoyable. He’s great. No need to change”

“Mr. V did a great job of going through examples and provided plenty of opportunities to get help.”

“Professor V is overall a good professor who presents material efficiently and for the most part understandably. I appreciate how he demonstrated phenomena we were learning about in class. I appreciate that he answered questions in class. He provided very good visual experiments to introduce new material.”

“He is very enthusiastic and knows his material.”

“Mr. V’s demonstrations are incredibly helpful to understand the concepts and be able to visualize what is occurring in the world and in class. He teaches the information very well and it is pretty clear what he wants from you. He is always willing to help students and genuinely wants them to do well.”

“This material was significantly more difficult than last semesters, but I found that the teacher presented this material more clearly and at a better pace. The experiments that he did in class were extremely interesting and kept the entire class engaged.”

“Very well spoken, encouraging and funny. Knows the material well and does a great job of explaining difficult concepts with clear demonstrations. Very open in office hours and willing to help. As a professor, he is at first glance abrasive, but with more understanding, very genuine and determined to provide the best for his students.”

“-straightforward, no “beating around the bush” -willing to help students -lectures timed well -clear slides -video recordings of lecture helpful -responds on piazza very quickly! Gives many examples to better the understanding of the materials.”

“Mr. V was enthusiastic about teaching and made the material very understandable. Great at explaining difficult physics topics directly and clearly.”

“I really appreciated all the different resources he provided us that aided in learning. The WebAssign homeworks were reasonable, the lectures were fast-paced but provided good example problems, having old slides helped me focus in lecture, and the demonstrations were always enjoyable and taught concepts well.”

“Mr. V is very good making physics less intimidating and easy to understand. His demonstrations of concepts in physics through small experiments are very helpful in understanding the course material.”

“He is able to clearly articulate and explain physics.Great guy, and knowledgeable. Sometimes difficult to understand and read handwriting, but it is math not English.”

“Mr. V is really nice! He tries his absolute best to provide necessary information for students to pass. He has EXTENSIVE office hours. I legitimately think he is the hardest working teacher I've had at BU - he uses these presentations to explain concepts and is EXTREMELY aware of things that people may not like (fast pace, accent?) and tries his best to accommodate for this. He is doing really, really well as a teacher and I understand why people prefer summer physics because of this.”

“He was always prepared for class. He posted the slides in a timely manner and despite the class being and hour and a half long at 8:30 in the morning, he still made a good effort in being enthusiastic.”

Elevator Pitch

One of the first statements I tell my students is that the most important ability for succeeding in a physics course (and in life) is not mathematics, or even logic, it is imagination (and persistence – but that is obvious).

Imagine that you are on a plain (or taking a train, or a bus), and talking to your neighbor.

Turns out, he is in education; for years has been teaching math, logic, problem solving, but lately mostly physics; developed and taught courses to middle school students, to high school students, to college and university students, to students with learning disabilities; has a M.S. in Theoretical Physics and a PhD in Education with focus on teacher professional development; taught courses to teachers; consulted school and district officials on managing innovations in education; was a consultant to a state department of education to help with writing a program for strategic development of the state system of education; was an assistant to a director of a regional institute for teacher professional development and an administrative assistant to the chairman of the board. I ran an institution responsible for development of analytical documents and policy recommendation for the department of education of a city of the size of Boston (and often did all this at the same time).

No doubt, you would think that this guy was an expert in the field of education: an expert in teaching, an expert in advancing teaching practices.

This guy is me, Dr. Valentin Voroshilov. I was wearing all those “hats” in Russia before I moved in Boston. My career was very promising, but I gave it up for a chance to give my family a broader future.

At the time, I had no publications in English. I didn't even speak English. Hence, after I moved, all my professional experience was bottled up inside me for many years to come. I had to start from a square one. First as a janitor, learning English using books, radio, and TV shows.

Today I have recovered the most of my previous career (very proud of it!): until my retirement 2021 I worked full time at Boston University, I teach (mostly physics) and I am good at teaching; finally I can clearly express myself beyond a physics course; I’m productive and I publish in English!

Based on my professional experience, I consider myself a driven professional (educator), an eloquent expert (in human intelligence), a productive author, and a collaborative colleague.

In the end, I have a very broad teaching and research experience. In one word, I have become a TeachSmith, so to speak (not bragging, just stating a fact). The journey from a teacher to a TeachSmith was long and wavy, but not unique, has many shareable elements common to every professionally growing educator (and summarized in book “Becoming a STEM Teacher”).

Cover Letter

Dear Colleagues,

At the top of my Russian career, before I moved to Boston (in 2002) I ran an institution which was an analytical branch of the City Department of Education of a large city with about 1,000,000 citizens and about 130 schools (most of which would represent an equivalent of the combination of American elementary, middle, and high school together). And before that I was in the field of a teacher professional development (please, see below for the details).

But my main professional achievement is being a good teacher. I am a highly-experienced educator. I have been successfully designing and teaching my courses and helping to design various courses to many educational professionals. As an instructor, I am definitely above the average level, with a solid formal proof of that fact in the form of my student evaluations; with a strong conceptual view on what teaching is and how to teach effectively, efficiently, and sufficiently; with an experience in inventing and implementing into a teaching practice new and effective teaching instruments helping students develop deep understanding of the subject (physics).

The rest of this letter details my experience in the field.

“He is a master. I think all professor should be able to teach as him. That way students would not have to spend hours reading off of lectures.”

“I can honestly say I had never seen a professor who cared more for his students and how they do, as well as what they learn.”

“Thank you, thank you, thank you! Mr. V, thank you for putting up with all of us this summer!! I feel much more prepared for the MCAT. And I loved the demonstrations! Thanks for putting all the time + effort!”

“Professor V, You designed this class so that those who put in the effort would succeed, so I gave it my all and sure enough. I want to say thank you for creating such a conducive learning environment for me to succeed. I hadn't taken a physics class since my freshman year in high school, so I was very nervous going into your class. I did not expect this course to become my favorite science course so far at BU. Physics is a hard subject, but you explained everything well and made sure we, as a class, had the tools necessary to succeed with enough hard work on our end.”

These are quotes from many nice words said about me by my former students.

I believe, such a feedback is one of the greatest rewards any teacher can have.

Three times since my university graduation, I had to re-start my professional career from a square one. This feedback is one of the proudest achievements of my professional life.

Dear Colleagues,

I believe your view of an educator, is similar to mine, i.e. at the core of an educator is a person who loves learning, who is good at teaching, good at understanding the logic of learning and teaching processes, one who can clearly express that logic to students and to colleagues, the one who can think outside a box, who can create non-obvious solutions to non-traditional problems, one who can help colleagues becoming the best teachers they can be.

A good teacher is a teacher who can teach not only memorizing and repeating various – even very complicated – patterns (that is essentially no different from training animals doing tricks – BTW: that is what all current AI-systems do); but also beyond; i.e. a good teacher is a teacher who, in addition to solid knowledge and skills, can teach how to think creatively and critically – which is the essence of Human intelligence. Currently the AI filed has no common definition of Intelligence, that is why I have developed my own. Intelligence is an ability to create a solution to a problem which has never been solved before. My definition not just grasps the quintessence of intelligence, but is also operational, i.e. measurable (hence, teachable). For me, the vital and ultimate goal of teaching is helping students to advance their intelligent abilities, i.e. helping them become truly human.

“I have a very particular set of skills, which I have acquired over a long career”. My student evaluations are the result of my extensive and successful professional experience in the field of education.

I have no doubt, I would be a good fit as a member of a professional team of educators.

What may make me stand out of some other educators is the breadth and deepness of my professional experience – due to my good luck of working in many areas of the field.

I have a deep knowledge of the main subject I teach (M.S. in Theoretical Physics), as well as augmented subjects (math, logic, problem solving, human psychology, methods for teaching); I am an expert in teaching methodology and teacher preparation (PhD in Education, experience in consulting teachers and administrators); I have a deep knowledge of Human Intelligence; I have an extensive and successful tutoring, teaching and research experience; I believe, all this makes me a teach-smith (so to speak).

I have a successful experience in designing and teaching courses for middle school, high school, college and university students, pre-service and in-service teachers. I have a clear vision of the structure of an effective on-site or online science courses (the latter should be more than a standard combination of “talking heads”, hyperlinked texts, screen simulations, and chat rooms).

A joke “those who cannot do – teach; those who cannot teach – teach teachers” is definitely not about me.

I could have become a physicist. I could have gotten a PhD in Physics. Anyone who could get a B+ in elementary Quantum Mechanics can get a PhD in Physics. And I aced Quantum Mechanics, as well many other subjects, e.g.  multivariable calculus, linear algebra, differential equations, hydrodynamics theory, particle theory, electrodynamics, renormalization group, and even taught group theory to university faculty. So, I could have gotten a PhD in Physics, but decided not to use my time to getting another badge of honor. However, to prove it to myself, in 2010 (not ever doing physics before that) I read some papers on high temperature super conductivity, and then wrote mine own, which was published in a peer reviewed specialized magazine (http://www.sciencedirect.com/science/article/pii/S0921453410006179).

There is, though, the seed of truth in the joke. It is just a fact that when someone is good at doing something, it does not necessarily mean that the one can also clearly explain what the one does, and why the one is good at it, because “clear explaining” is also a special skill. I am lucky to have this skill, and happy to offer it to students and colleagues. 

My professional goal is very clear – I work hard to maximize my professional output by applying all my skills and experience. 

Three times since my university graduation, I had to re-start my professional career from a square one and I think I can adapt to almost any working environment.

When I was receiving my MS diploma in theoretical physics, I thought I would be becoming a physicist. However, when the Russian economy collapsed, in order to feed my family, I turned to tutoring, and later to teaching middle and high school students, and then college and university students, and then teachers. At the time, schools were some of few places where the government sometimes paid some money.

Soon I realized that students liked my teaching, and I liked teaching students, and I started my second career – as an educator.

I joined a team of innovative teachers, administrators, researchers, and consultants. Our team has been running various teacher professional development activities, including a year-long projects involving teams from multiple schools, with the end of a year bootcamp for students and teachers. As the result, in addition to teaching, I also entered the field of teacher professional development, and educational consulting, and got my PhD in Education (specialization in andragogy, concentration in teacher professional development). My career was on a rise. But at the time leaving Russia was the only way for me to save my son from being drafted in the Russian Army (which at the time was not much different from Somali pirates). In 2001 a miracle happened – I won a Green Card. Professionally as well as economically, moving to the U.S. meant for me being greatly degraded (as from many immigrants), but I saved my son and hoped for the best.

When I moved in the U.S. I started my third career from a square one (my first job was a janitor at a supermarket). Since no one knew me, and I knew no one, and I spoke just very basic English (which I learned myself from books, tapes, TV and radio shows), the journey to reestablishing myself as an educator was not quick and easy. But today I teach, I write, I research.

I am proud of my current achievements, but I am always open to making another step in my professional journey.

For example, I am always open to more teaching and to a collaboration on development of new approaches to teaching and teacher professional development.

I have been involved in many collaborative projects which had led to the development of new curricula, new course content, efficient tools for managing teaching activities and learning experiences, facilitating teacher professional development, running professional development workshops for teachers and administrators.

I started my teaching career as a tutor. Tutoring may be very helpful for gaining a deep understanding of numerous reasons for different students to have various difficulties with getting a good understating of math and physics.

Some tutors would help a student to do the homework, and then a student would come back with a new homework, and then again, and again. For me it felt like cheating. I wanted to teach my students how to do their homework on their own. My goal was to help a student reach that level of understanding so he or she would not need me anymore. It may have looked counterproductive – money-wise. But in reality, it worked for me very well, because parents of my students talked about me to other parents, and I had plenty of clients.

Tutoring helped me to initiate the development of my teaching toolbox tailored to students with different background. People usually are eager to talk about gifted students, and how to help talented students to realize their potential. Struggling students do not often attract the same attention as gifted ones. Tutoring is like having a clinical practice. All good students are good due to mostly the same reason (a good background), but when a student struggles there might be numerous possible causes for that.

Teaching and tutoring physics, algebra, geometry, trigonometry, problem solving, logic helped me acquire an integrative view on various difficulties students may have and effective approaches to guide students through those difficulties. My Doctoral work was focused on the approach for igniting and supporting teacher’s sustainable desire to grow professionally, and on methods for helping educators to design the most effective path for their continuous sustainable professional development (teaching teachers about teaching requires deep and wide understanding of learning, teaching, and of the teaching subject).

In Russia I was a member of “Moscow – Perm Socratic group” – a collaboration of educators dedicated to promoting the Socratic Method of teaching.

I have a long and successful experience in teaching various mathematics and physics courses, courses for pre-service and in-service teachers and school administrators. I have been teaching Mathematics and Physics to almost all possible categories of students (i.e. to middle- and high- school students, 2-year and 4-year college students, university students, to students with learning difficulties, and to school teachers). I also have been teaching various curses for in-service teachers (in parallel with teaching math and physics).

For a number of years, I had been working at a regional institution for teacher professional development, providing various courses and training to teachers and school administrators.

Individually and as a member of a team I was consulting and auditing individual teachers, schools, and school districts regarding educational policies, teaching technologies, learning outcomes, and quality of education in general. Alone and with my colleagues, I was traveling to towns and villages of the Perm Region to meet with teachers and administrators and helping them with adjusting teaching and administrative strategies and techniques in order to achieve better learning outcomes of their students, including preparing strategic plans for systemic development of a school, a district and a regional education system.

My administrative experience involves running a department of computerization at Perm Institute for Continues Teacher Education, working as an assistant to the Director of an Institute and as an administrative assistant to the President of the Board, and later running the Center for Development of the School System of City of Perm, which was an analytical branch of the City Department of Education (my last position before moving to the U.S.).

I was hired by the Perm State (a.k.a. Region, a.k.a. Oblast') department of Education as a consultant to help draft the “Program of the Development of the State Educational System for the five-year period”. This was one of the highest levels of the recognition of me as a professional educator and a consultant.

After I moved in the U.S. and re-entered the field of education, I have been teaching Boston University PY105/106 Elementary Physics courses, as well as College Mathematics, Physics and Problem Solving at ITT Technical Institute (Norwood, MA), Wentworth Institute of Technology, Bridgewater State University, BU High School Academy.

During the years of my teaching practice, I have developed numerous math and physics middle-, and high- school and college curricula, syllabi and lesson plans; problem sets, worksheets and hands-on activities. I have an experience in developing websites and using such ones as webct, moodle, blackboard, webassign, masteringphysics, wileyplus; creating new demonstrations, filming movies and posting them online, using Java applets and audience responds systems (eInstruction, Turning Technologies); developing laboratory experiments and writing manuals. I have been and am using different teaching strategies, including different media to motivate students to learn and to help students to master a subject.

My years of personal tutoring and teaching provided me with invaluable insights into how people learn and how to help them to master a subject and to become a more efficient learner (my teaching philosophy is presented below). I have been sharing this experience with many students, teachers, and colleagues. I have strong communication skills, deep understanding of pedagogy, wide teaching experience, and competent in using a variety of educational software products.

I firmly believe in a scientific approach to teaching and to research on teaching. A teacher should be able to state specific goals, list the assumptions, formulate the criteria of a success, and establish measuring tools and procedures, and a researcher should be able to do the same as well. I am also convinced that contemporary technologies will allow to bringing teaching to a new level.

My personal teaching experience has always been entangled with my research and consulting practices, and this entanglement represents one of the most helpful assets I have and use when working with students, colleagues, teachers, and administrators, because I usually know what students, colleagues, teachers and administrators may want or need, what obstacles they may encounter and need to overcome, and how to help them to do that.

I am a team player, the goals of my team always set limits and directions for my personal professional goals. Throughout all my professional life as an educator I have always had good relationships with my students and colleagues. I always respect all my students and they know it, and they respect me back even if at the end of the course they do not have the grade they would like to have.

I am confident that my teaching, research, and administrative experience would let me to be a serious asset for a team of innovative educators, specifically, effective instructional designer.


Dr. Valentin Voroshilov

P.S. What usually confuses HR associates is the fact that never in my life I was holding only one professional position. Since the time when I was a middle school student, in addition to taking classes or having a full-time position, I had always had some additional job or jobs on a side, and then later in my professional career I held at least two official positions, and sometimes even three. And I firmly believe that my “extra” experience only amplifies my experience, no matter which specific professional position I would hold.

When I was becoming a manager, my mentors taught me that the number one quality of a manager is character, because without character one cannot be decisive, cannot make decisions, especially if they involve risk, hence cannot properly execute his/her function as a manager - making decisions. However, I have also learned, that character is important for anyone to succeed. The fact that I re-stared my career three times, and twice overcame severe financial hardship proves that.

My reflection to the voices of my students.

First, one might ask why do I post all that feedback, isn’t this just bragging?

No, it is not just bragging.

I write on education, and I want to demonstrate that I know what I am writing about.

I know about education not from books or theorization.

I know about education from books, from my own theorization, and from my own highly successful teaching experience, from my whole educational practice.

I believe that having this type of a feedback shows that overtime I have made a transition from being a teach-er to becoming a teach-smith :)

The first two paragraphs above are copies of the thank-you cards I got from two of my former students, the rest is the quotes from end-of-a-course (elementary physics I and II) student evaluations from 2008 to 2017 about me and the course I have designed. Those quotes represent about two thirds of positive (mostly) views expressed by students (the other third expresses sentiments very similar to already presented). It is worth noting, that many comments go beyond just “he is a nice guy”; many comments underline the fact that the course is designed to help students to get good understanding of physics.

Do I have any negative reviews from my former students?

Of course! (the copies of full evaluations are available on https://www.cognisity.how/2019/09/feedback.html and (the older one) http://gomars.xyz/mathhealth/myinfo.htm but why would I presented here everything negative about myself? :) )

Having only positive reviews is unnatural for a teacher of a large class. When one has several dozen students with different backgrounds, different expectations, different cultural habits, and psychological inclinations, it is inevitable and unavoidable to have student who did not like the way one teaches (due to a list of possible reasons).

The first question is – does the teacher have more positive or more negative reviews?

Well, in my case, if I had more negative reviews than positive ones, I would not be allowed to teach these courses for so many years.

Since I am a teacher, it seems natural to me to evaluate my skills by comparing them with the skills of other teachers. Unfortunately, I have no access to statistic on other BU physics department faculty; I would even think that this statistic might not even exist. “Fortunately”, www.ratemyprofessor.com gives some glimpses of “comparable” “data”. Surly, no one can take seriously what students post on this site, at least until hundreds of students would express their opinions on the same professor. However, even with this amount of “data” we still can see some interesting patterns. There are faculty whose average rating is high because the most of the students’ ratings are high; there are faculty whose average rating is law because the most of the students’ ratings are law; there are faculty whose average rating is average because the most of the students’ ratings are average. But there are also faculty whose average ratemyprofessor rating is average because students’ ratings are very opposite (some give a high rating but some give a lower one). So far my ratemyprofessor rating is of the latter kind (good thing is that my official BU student reviews aren't such; but one can ask a general questions – what is more important, the average rating or the highest one?).


This is the glimpse of some of the reviews taken from the ratemyprofessor:


Mr. V was honestly the best professor I have had at BU. I never take the time to rate my other professors but Mr. V is worthy of the praise. He made the summer course worthwhile. His demonstrations were great and his humor always made my day. Go to office hours, do the web assign, and you will learn a lot. He is an awesome human. Thank you


Not fair. First exam was easy. But other exams were ridiculously hard. Exams are much more difficult than HW problems. Handwriting is horrible and it is difficult to understand him. Never tells what is exactly on the exam. Expects you to study everything he gives (labs, discussion, lectures, webassign, etc). Not clear at all.


I was very worried coming into this class, having ALWAYS struggled with classes like Physics. I was also worried when I heard Dr. V's strong accent. However, after taking 2 straight summer courses with Dr. V, he has proven to be an incredibly nice, caring, and funny professor who really wants his students to succeed! GO TO OFFICE HOURS, DO HOMEWORK


Very difficult to understand. Homework questions are not like questions done in class. Goes through too much material far too quickly. Do not take this class over the summer.


I took PY105 in the summer and although I honestly dislike physics, I did enjoy Mr. V's lectures. I guess his accent's gotten better because our class was the first to not complain about it (2016). The exams are generally difficult but graded more leniently that most other BU courses IMO. I'd love to have him for physics again for 106, he's chill.


Very hard professor and moves at the pace of a fast train. he does not go through examples and thinks people understand concepts when they do not really. i really wish he would solidly lecture/explain more.


Val is a great professor. He is somewhat difficult to understand and his handwriting is atrocious, but overall he does a good job getting the concepts across. He has some awesome in class demos which are fun to watch. He tests very similar to the homework problems, so if you understand the homework fully you'll be fine.      


Expects you to have read ahead of class and memorized everything. there is no required textbook, but he takes class problems, homework, and test questions from the one that he recommends, which is not helpful at all. he speeds thru things and doesn't give one time to write or properly digest the info. if he's teaching, take physics later.


You would probably prefer having a GOOD teacher, and tried to avoid the BAD one. But the fact of the matter is those two descriptions depict the same person, i.e. me (BTW: on the first day of each new class I always show to my new students a much longer list of pros and cons)!

I think this is very solid proof of the fact that different students have different learning styles and different teachers have different teaching styles, and sometimes those styles match and sometimes they don't.

It is clear that students’ opinions about me are polarized, and I am absolutely fine with that.
Probably I am the only professor who is accused of a "grade deflation", the quote: “grade deflation is the craziest concept to exist in a university setting. This is a physics course. A 93 should be an A period. In what world is a 93 not an A?”

That is when everyone talks about grade inflation.

The large part of my first lecture is devoted to presenting to students my views on physics, on teaching, on learning, on grading, and on my expectations about students (for example, take a look at this short video: https://youtu.be/E8776nfGNX8; over the years I have posted many short YouTube videos, including videos on what is physics and how to solve physical problems).

I always mention a simple fact, that different students learn differently, people have different learning styles, and different teachers have different teaching styles, hence, there is always a chance that my teaching style does not math somebody's learning style. What to if that happens? Well, a student will have to make a decision – stay or go to a different teacher. So far (knock on wood) I represent a good match for the majority of students taking BU PY105 and PY106 courses.

Among negative reviews the most common themes are: an accent (Russian), handwriting (guilty, my handwriting is not much better than the one of a regular doctor), too fast (well, the average speed of covering the material is equal to the total volume of the material divided by six weeks of the course), do not answer questions in full (that is sometimes true, it depends on a question, sometimes I just cannot spend much time on repeating the material learned two weeks ago and only can point at the material which is needed to be reviewed again), too forward/direct with students (for example, when asking direct questions; an interesting observation – you ask a direct question to a student in a lecture and the student “shrinks”, but there is almost no problem if it happens on office hour).

I believe that for any teacher the list of positive reviews from students should present the best recommendation for a teaching job.

When I left my comfortable life in Russia and moved to the US I did not have professional network to rely on, or money, or language. It took me some time to finally land at Boston University physics department as a laboratory assistant. Gradually my English got better, and my knowledge of the new academic environment got clearer. After three years I got a promotion to run a demonstration facility. A year after I started teaching BU elementary physics courses, and I have been teaching physics since then. During the last several years, in addition to my full-time position at the demonstration facility, I also have been teaching, and traveling to different conferences with posters or presentations, and publishing various papers, but my dream has always been to became a full-time physics instructor.

I have an experience in research on teaching physics, I have an administrative experience, I have been helping to schoolteachers and administrators to improve teaching environment, but at my core I am a physics teacher.

My teacher philosophy, my views on what is teaching and what is learning are presented in my book “Braking the Mold of Conventional Thinking: a Personal Quest for Teaching Philosophy” available at https://www.smashwords.com/books/view/665204 (the short version of my teaching philosophy is below).


Statement of Teaching Philosophy

(for the broader version, please follow to: http://www.cognisity.how/2017/11/method.html)

Dear Colleagues,

Below you find a very short version of my teaching philosophy, which has been presented in great details in my book “Becoming a STEM teacher”. In chapters “What is Learning”, “What is Teaching”, “How I flipped my classroom without even knowing it”, “What does “Thinking as a Physicist” mean?”, and others I lay down the results of my reflection upon years of my (mostly successful) teaching.

I believe that learning is more than just acquiring a certain set of skills and prescribed amount of knowledge. Learning is an important cultural process which happens when pupils (students) are being brought into the realm of relationships and traditions which should allow them (a) to prosper in the current society, and (b) to become active agents of the social progress.

I believe that a teacher is more than just a “walking knowledge storage” who imparts this knowledge on students and judge how good students have become at reproducing the knowledge imparted onto them. My definition of teaching is: “Teaching is guiding students through a specifically designed set of learning experiences (a.k.a. student activities) to help them to develop or advance desired skills and knowledge.”

A teacher is a guide, who had become an expert in a certain field, and now helps students to begin and to walk a path to becoming an expert in the field he or she wants to become an expert. In order to guide students as efficiently as possible, a teacher has to use (and often develop) specific tools/instruments students should use when immersed into situations specifically designed to help them mastering designated skills. A teacher might be not the one who designs the whole set of student activities and corresponded learning tools, but he or she generally should have a deep understanding of the reasons for the use of the activities and tools.

Students are not empty vases needed to be filled up with wisdom, not tabula rasa on which a teacher scribbles smart things. Students have certain world views, they have certain understanding of how the nature works, and a teacher cannot ignore ideas, conceptions, preconceptions (some of which might be incomplete or incorrect) students have when starting a course.

The goal of learning is to achieve a higher level of competency.  Passive learning does not work. Strictly speaking, passive learning is not really a learning, it is just a precursor for an actual learning.  A true learning happens when students are actively trying to merge new knowledge (usually presented to them by a teacher live or via mediating media – books, videos) with the previously internalized knowledge. Very often students run into contradictions, some of which are often called “mistakes”. However, the only truly real way of learning is through making mistakes and reflecting on how those mistakes had been corrected.

One of the most important qualities of a teacher is ability to guide students through mistakes they make (maneuvering between giving away the answer and making students feeling desperate).

When assessing student’s progress, a teacher is not a judge, but rather an auditor who has to present to a student the accurate measure of student’s achievement (or a failure).

In the end, the most important measure of a teacher’s success is good feeling students have about themselves, the course, the work students done during the course and the results of the work; and also the reputation of a teacher students pass along to fellow students.

That is why the simplest definition of a “teacher” is “the person about whom someone said at least once – I’ve learned something valuable from that guy!”.

My ultimate goal is to change students’ aptitudes about themselves and about physics. Many students are afraid of taking physics because they have an impression that physics is only for selected few, that succeeding in physics requires super intelligence. This impression is wrong. Anyone who is capable of solving quadratic equation and knows the multiplication table can learn physics. There are only two requirements for achieving a deep understanding of Physics:

# 1 - a good teacher;

#2 - a good student.

Being a good teacher means having a proof of a successful teaching (e.g. the voices of my students).

Being a good student means putting effort in learning.

If you are a good student, you don't give up, you try and try again, and you are actively guiding your or learning by making your teacher work for you. If something is not clear for you, if you feel like you don't understand something - it's not your fault; it only means your teacher needs to find the right way adjusted  specifically to you to help you to master the subject.

If a teachers does good job, students not only learn the subject, but they also change their attitude to more positive side.

For example, my students always demonstrate the positive shift in their attitude.

I always tell my students that there are science courses which represent the material simply as a collection of a disconnected facts. Courses like that do not represent students with the scientific way of thinking. Many people in the field of education for a long time have been propelling the idea of teaching students how to think critically, but they could not offer the method for how exactly this could be done. However, the method has been around for at least several hundred years, and is called – science thinking. The true science course has to guide students through the scientific way of thinking using the course material (i.e. facts) as the building bricks of the science students learn. This is how my physics course is developed and taught.

Naturally, not all student like my approach, the evidence shows that some of them definitely do.
