To All Current and Potential Colleagues

(click here for a pdf version of this page)

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 (http://www.teachology.xyz/evvv.html); with a strong conceptual view on what teaching is and how to teach effectively, efficiently, and sufficiently (http://www.cognisity.how/2016/10/book.html); with a strong experience in teacher professional development (http://www.cognisity.how/2016/10/facilitating.html); 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), (http://www.cognisity.how/2018/04/MOCC.html; http://www.cognisity.how/2018/02/Algorithm.html; creativeness,  and critical thinking http://www.cognisity.how/2018/02/thinkphy.html; http://www.cognisity.how/2018/03/ZPD.html).

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 (this link GoMars.xyz/evvv.html provides more examples, including the latest).

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 (by the host of Intelligence; Cognisity.How/2018/05/AHLI.html). 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 (and I teach this to my students, no matter what specific subject I teach at the time; using my own technique: Cognisity.How/2018/02/Algorithm.html; Cognisity.How/2018/02/ThinkPhy.html).

“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 any professional team of educators.

What may make me stand out of some other educators is the breadth and deepness of my professional experience.

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; GoMars.xyz/TeachSmith.html).

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. 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).

I love working with teachers, but not because I cannot teach students – on the contrary, my student feedback tells me that I am a good teacher. I love working with teachers because I am good at teaching, and I have professional experience I would love to share. A large portion of my experience in the field of teacher professional development was summarized as a chapter in a book (Cognisity.How/2016/10/facilitating.html).

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 (GoMars.xyz/vv.htm) and but I think I may be ready to my last transition.

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). However, I did not like the changes in the political atmosphere. In 2001 a miracle happened – I won a Green Card.

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 not afraid of making the next step in my professional journey.

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 told 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 (Cognisity.How/2018/02/Socrates.html).

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 President of the Faculty Assembly of the Institute, 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 summarized at Cognisity.How/2017/11/method.html). 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.


Sincerely,  Dr. Valentin Voroshilov (Cognisity.How/2018/02/Iam.html)


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 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.

In this short essay, I will try to summarize my views on 

what is teaching, what is learning, 

and why everyone should learn physics these days.

Since I am not so special, every STEM teacher can use a similar set of views.

(a copy is available at: Cognisity.How/2017/11/method.html)

What is teaching?

Below is the quote from Google search on: “what is teaching” (the top answer):

The second meaning of “teaching” is transparent: “teaching is a synonym for philosophy”. But the first description does not really say much what teaching is. “Teaching is what a teacher does”.

Everyone wants to be healthy and successful and no one wants to be ill and poor. The only difference is how we want to achieve our success. There are people who use other people as a tool for climbing the social ladder. I would not recommend people like that going into teaching. Children feel when they are being used and always find the way to escape – one way or another. Anyone who wants to be a teacher (or an educator of some sort), should do it to help children to succeed in their life, and they will return the success.

Teaching is an important human practice. Many people think that teaching is simply telling students “do as I say”. This very approach is built in our DNA. Our parents used this approach when teaching us. Animals use this approach when teaching cubs, pups, baby birds (they rather use the “do as I do” version, which is also very popular among humans).

If teaching was indeed merely “do as I do” or “do as I say” practice, then of course everyone could do it! Teaching would not be much different from training animals (“a stick and a carrot” would do the trick).

Clearly, teaching is something more complicated than just “do as I say”. Not everyone can become a good teacher. Everyone can cook at home, or drive a car. But not everyone can become a successful chef or a racecar driver. And when we say this out loud, it does not sound controversial – because it’s obvious! Yes, we know that some people are a better fit for some practices than others, and some people are not a good fit for some practices. In particular, some people are just not fit to be teachers (which is not their fault), and one of the goals of every teacher preparation program should be identifying those people and helping them to find another professional path.

So, what is teaching, or, what does it mean to be a teacher?

I think that the answer to this question forms a fundamental basis for the whole professional philosophy of a teacher and for the practice built on that philosophy. One of the first indicators of a true teacher is that he or she has a certain answer to this question. I also believe that there is no single correct answer to this question. I believe that every teacher should search for and find his or her own answer (although the answers might sound very similarly).

In this essay, I want to share my answer to the question “what is teaching?”.

To me, 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 – this is my formal definition of teaching (hence, a teacher is a person who teaches in accordance with this definition; this link leads to short statements about teaching which I call “Laws of TeachOlogy”; http://www.cognisity.how/2016/12/handbook.html).

A teacher might not be the one who designs the whole set of student activities, but should have a deep understanding of the reasons for the activities and measures of the success or failure of the activities.

We all know the old saying that one can bring a horse to water but one cannot make it drink. Well, a teacher cannot make a student learn unless that student wants to learn. Unfortunately, too often students start to learn only to avoid some kind of punishment. This kind of teaching might happen when a teacher does not care much about students, but just functioning to avoid being fired (mimicking/faking teaching). On another hand, a teacher might be very forceful on students (“It is for your own good”) to become being praised. I believe, no matter what a teacher does, students should not have any psychological damage (like, “feeling stupid”).

Teachers - like doctors – should take “a Hippocratic Oath” of a Teacher and promise “never do harm to anyone”, because there is always something more important in teaching than merely transmitting knowledge or training skills. A true teacher knows the limits.

Ideally, parents should be the first true teachers.  The best gift a parent can give to a child is good habits and love for learning. The same is true for a teacher.  Look at infants and little children – they always try things and want to learn something new! Now look at school graduates – so many of them do not want to learn anything new anymore (or cannot learn anything new, which is even worse). If children have lost their curiosity and desire to learn, that only means they did not have a true teacher in their life.

A true teacher is not the one who just loves teaching (“do as I say”), but the one who also loves learning. The art of teaching is based on love for education, and passion for sharing this love (and also on the science of learning).

Every student has his or her own learning style. Every classroom is different from another. Teaching constantly presents challenges: students do not act the way a teacher expects, parents or officials put pressure on a teacher. If a person cannot withstand challenges, that person should not go into the business of education in any form; she/he is not going to be a good teacher, or administrator or a researcher in the field.

No one is perfect. Everyone makes mistakes (the difference is what we do after we made it). Mistakes are an inherent part of our life. Mistakes are inevitable and unavoidable. Especially when people learn something new. A teacher should understand that students will be making mistakes. Learning is based on continually overcoming mistakes and learning from them. If a student did not learn something, which he or she was supposed to learn, chances are that it was because a teacher made a mistake. A true teacher never stops learning (mostly because no matter how good we are there is always a room for improvement: new students are different from the former ones, world changes, a new year is never the same as the previous one). And a true teacher is always open about mistakes he or she has done, even (especially!) if it happens in front of a class.

To summarize, what does make a teacher to be The Teacher (or a Teach-Smith, so to speak: http://www.cognisity.how/2017/12/TeachSmith.html)?

Patience, love of learning, understanding and accepting personal limits, genuinely caring for students (they intuitively feel if for the teacher they are just pawns in his/her game for personal success), constant professional development – including, but not limited to – having deeper knowledge of the content of the subject he or she teaches, deeper understanding of the fundamentals of the knowledge development within a specific science (each school subject is a projection or a simplification of a certain science), deeper understanding of the fundamentals of the knowledge development in general, understating of human behavior in general and behavior of a child, understanding of the fundamentals of human learning and teaching. From a procedural point of view, the simplest model of teaching is “teaching = motivating + demonstrating + instructing + explaining + assessing”, hence a teacher should have personal qualities, knowledge and skills which will allow to be able to motivate, demonstrate, instruct, explain, and assess (within the limits placed by “do no harm” rule).

A true teacher is not always the one whose professional description says so. A teacher is a person about whom other people say that they have learned something important from that person.

There is one controversy I would also like to address. Many people (including policy makers, parents, business representatives) think that to be a good teacher one just needs to know the content. But, that is not true. The content knowledge is one of many components of a good teacher, and not the most important one. Firstly, I have met people who had excellent content knowledge but were terrible teachers. I had professors who were at the top of the achievement list in academia, but who could not teach at all (they were very interesting storytellers, though). Clearly, they knew how to do difficult science and they did it. But they could not explain what they did, and why. Secondly, content knowledge is just a result of a certain amount of effort. Any reasonable person who spends a reasonable amount of time can obtain content knowledge in the amount sufficient to teaching at a reasonable level. Personal qualities like willingness to learn till the first day of the retirement (at least), patience, etc. are also very important for becoming a true teacher. A teacher is - first - a person, and - second - a knowledge storage, a skill presenter, a guide, a trainer.


What is learning?

A dictionary tells that learning is:

* the acquisition of knowledge or skills through experience, study, or by being taught.

* knowledge acquired through experience, study, or being taught.

For a teacher, this definition may be a starting point for reaching a deeper understanding of how people learn.

The first fundamental notion is that learning is a basic need, like food, or oxygen. There is a “slight” difference, though. With no food or oxygen, a person ceases the biological existence (a.k.a. dies).

Without learning a person ceases the social existence (the reason for all dictators to micromanage education - they are scared of free thinking which comes with true education). Learning - as a process and as a result - is solely responsible for the prosperity of a society (even if the prosperity still is very uneven).

Secondly, learning is a process; it has phases, it has stages (that is why a college does not accept middle school graduates). Learning stages might differ in length and difficulty, depend on many parameters (subjective like age, race, brain development of a student; contextual – what science is this subject about; social – culture, traditions, economics), but they are as objective as stages in the seasons we observe every year. The existence of these stages results in the existence of the specific patterns of learning, which must be reflected in the specific patterns of teaching.

We cannot jump from a spring right into a winter; similarly, we cannot jump into learning quadratic equations right after learning the addition within a hundred (the normal process of giving a birth requires 9 months and should go through well-established phases - from an embryo to a baby: the process of “giving a birth” to an educated person– from having no knowledge and skills to having them - also has specific stages). If despite our best efforts a student did not learn how to solve a quadratic equation, it means that his/her learning path had missed in the past some of the important stages (assuming that students’ learnability is adequate).

Thirdly, learning is a result, it is an achievement. There are many achievements in our life, which – kind of - just happen; learning how to walk, learning how to talk. Achievements like that happen usually in a natural way, they do not normally require special prolonged management, do not have to be controlled, assessed, regularly measured, at least if everything happens as expected.

However, reading and writing, adding and subtracting, solving equations, etc. are skills; and to learn those skills a special and longitudinal effort is required, and hence, these skills have to be assessed. What needs to be assessed, how, when and by whom, however, are some of the most controversial questions of the contemporary research on education.

True learning never happens by just watching and listening (i.e. by merely attending lectures), it happens by doing. One can observe every cycling tour; interview every famous racer, that will definitely help the one to understand the theory of biking, but to learn how to ride a bicycle one has to ride a bicycle. One can watch for hours other people swimming, but if one wants to learn how to swim, the one has to get yourself into water and start trying. In the latter case, it would help having around someone who could explain what one does wrong and how to correct it (a friend screaming “you can do it, you can do it” would not be much of a help).

Active lectures help to boost motivation, develop vocabulary, give a perception that things are not as hard as they seem. Reading (and watching, and listening) also helps to form a vocabulary, to strengthen some relationships between the current knowledge and the upcoming one, to ignite curiosity, to boost imagination, to reinforce self-discipline, to advance mental capacities.

However, skills are only formed by doing.

For example, if the only exercise students had been doing for 12 years is squats, they will not be good at push-ups and pull-ups. If we want students to develop a certain skill, we have to give them an opportunity to practice that skill (ideally – as long as they need to master it).

Our brain is acting in a way similar to how our regular muscles act. Memorization is a mental activity very much different from creating new images, searching for new meanings, describing new phenomena, or developing new approach to solving a problem (during different mental activities a brain does a different work). Hence, if for 12 years in a school students only have been memorizing facts, it is not reasonable to expect from the graduates an ability to think critically, or to be creative.

Thinking critically is a specific mental activity, which requires comprehensive methodology, meticulous planning, detailed procedures, and designated time (much more time than just memorizing and retrieving facts).

Our brain is a powerful pattern recognition machine. As soon as it recognizes the task, it retrieves from the memory the sequence of the actions, which has to be performed to succeed. Of course, we assume that that particular brain is capable of storing and retrieving the information and governing the actions required for fulfilling the task (otherwise we have to discuss a case of learning disabilities). If a brain does not recognize the task, we have two options: (a) the task is the same but due to some features it is camouflaged as a different one; (b) the task is different and is really new for the brain and the brain does not have the solution (at least in full) in its storage.

Every teacher has to teach students to two different practices: (a) how to perform specific tasks (the set of those tasks should be specified by a curriculum); (b) how to create a solution to a problem which has not been solved in the past (by that person); the latter practice, in turn, requires a practice in making a conclusion regarding the familiarity of the given assignment - is it the same as one from the past (a task) or different (a problem)? Development of that skill also requires specific practice.

Teaching thinking critically (a.k.a. creatively) means teaching how to create solutions, invent actions/procedures which have not been presented/trained before.

In general, the answer to the question “what is learning?” depends on the interpretation of who is asking this question. For example, one can believe that learning is …

1.      memorizing facts and excelling in performing certain task (actions). Or 2.      obtaining knowledge and developing skills which will allow to create (a.k.a. “construct” – for those who loves constructivism, as I do) solutions to problems which have never been solved by the person in the past. Or 3.      from a procedural point of view, the simplest model of learning is   

Learning = goal making + memorizing + reiterating/practicing + thinking/analyzing + self-assessing (reflecting on the actions done during the problem-solving process).

My personal definition of learning is a combination of all the three above.

I believe that teaching how to think critically, teaching how to create solutions to new problems is the most important goal and the most difficult task of the contemporary education. If a person cannot solve any new (for that person) problem, it is hard to expect this person would generate some knowledge (or product, or business) new to the society. However, if a person can solve problems which he or she has not solved in the past, there is at least a chance that that person would give us something absolutely new and unexpected (good or bad – that is a different conversation). We should keep in mind, though, that critical thinking cannot be learned without a solid foundation in facts and skills.


Why Physics?

It has become a common place to say that American schools need to attract more students into STEM related fields (http://www.cognisity.how/2017/02/borders.html).

I believe that physics represents a door into STEM education (http://www.cognisity.how/2017/01/dorrSTEM.html). If students get confidence in physics class, they will feel confident in any science. Physics is one of the oldest and most developed sciences, hence it has a very clear logic and a straightforward learning methodology. Also, nowadays physics or physics based approaches can be found far beyond physics itself, for example, in medicine, in business and finance, even in sport (more at: http://www.cognisity.how/2016/12/learnphy.html).


What changes does US education reform need?

Education needs its own “Manhattan Project”, or “Apollo Program”, which would reexamine the well-established paradigms, and would guide a broad search for new connections and correlations; which would combine newly presented advances in artificial intelligence with neuroscience to study and analyze multi-layered universe of individual, group, and institutional learning and teaching; which would bring in education newly developed technologies, including AI, virtual reality, augmented reality, top level robotics.

This type of a program can be initiated via institutionalizing a collaboration between various professional and scientific groups by establishing a specific institution –an Institute for Learning and Teaching (the name is tentative, of course).

Within this Institute, professionals from various universities, intuitions, and companies would be able to join their effort and expertise (more at http://www.cognisity.how/2017/11/PILT.html).
