Teaching Philosophy
Teacher:
Children, write down the proposition:
“The fish was sitting in a tree.”
Pupil: But is it true that fish sit in trees?
Teacher: Well . . . it was a crazy fish.

What are my
general goals as a Teacher?
I believe that the most effective way of education is selfstudy.
As Ray Bradbury put it, “teachers are to inspire; librarians
are to fulfill.” This is especially true in engineering and
mathematical sciences: the only way to learn is through the independent
study and mastery of problems. It takes time and effort to deeply
understand a new subject by constructing examples, solving exercises,
and finding analogies with other already learned subjects.

However, the importance of the Teacher's
role in the process of Student's selfeducation truly cannot be overstated.
Obviously, selfstudy is extremely effortconsuming and, therefore,
requires strong motivation. So, my first objective is to inspire my
students, to show them why the subject I teach is interesting and
useful, and so motivate them.
Imagine a classroom of brighteyed
Freshmen. Having just entered university, they are highlymotivated
and eager to learn. How many of them will still be motivated and inspired
after the end of the course? Frankly, not all of them. There are several
reasons for that, and clearly the quality and style of lectures plays
a crucial role. So, my next very important aspiration is to design
my lectures in such a way that it allows me to keep the interest of
Students and the integrity of the knowledge simultaneously.
Finally, whenever someone learns a
new subject plenty of questions appear. Undoubtedly, I consider it
my responsibility to help Students to tackle their difficulties arising
during the course. To put it in a nutshell, my main goals as a Teacher
are to motivate and inspire my Students, to provide them with welldesigned
and highquality lectures and to be open for questions, discussions,
and collaboration.
How do I motivate and inspire
my Students?
Study without desire just ruins the memory. So, I always try
to explain to my Students why I teach what I do, why the topic is important
and interesting, and what kind of problems we are able to solve using
the corresponding concepts and notions. I hope that eventually my inspiration
will be transmitted to the majority of my Students and that they will
become intrinsically motivated.

However, I fully realize that there
is no way to motivate all Students in the classroom. There will always
be students without intrinsic motivation. I will try to help them
by extrinsic motivators in the form of rewards. People like to repeat
behavior that is rewarded and Students are no exception. A joint coffee
break or simple verbal encouragement can be a kind reward for good
performance. And the most important point is that extrinsic motivation
can, after a short period of time, produce intrinsic motivation.
What do I mean by good lectures?
First of all, a good course of lectures must reflect the current
state of the subject. I form a timelimited course in such a way that
it contains all the main concepts, notions, and illustrative examples.
Although my ambition is to cover as much important content as possible,
the quality of knowledge is definitely more important.

Next, the content is not what a course
is all about. I believe that the quality of knowledge highly depends
on the manner and style of lecturing. In my teaching, I combine two
popular lecture modes: using slides and using a piece of chalk. I
use slides to convey the most important points of the lecture and
for demonstration of visual information (e.g., graphs, figures, and
tables). I use blackboard for all computations and explanation technical
details. This allows students to follow the lecture in realtime and
gives them more time to digest new information.
The lecture style is also important.
When teaching a course for undergraduates I use more illustrative
examples in order to describe the underlying ideas. Unlike undergraduates,
graduate students have more background. In this case, I try to focus
more on applications, on different methods that can be used for solving
a problem, and on open research problems. Also I always remember that
it is difficult to pay attention for more than 20 minutes during a
lecture. So, timetotime I slow down and try to create space for
a new breakthrough. From my point of view, for this purpose there
is no better means than humor. Especially since there are plenty of
mathematical and engineering jokes.
Finally, a wellmade examination culminates
the course. I prefer openbook exams rather than closedbook, since
I like to test students' ability to solve problems using new knowledge
from my course rather than test their memory.
How do I know that my Students
are learning?
I like questions: I like
to ask, and I like to be asked. So, I always let my Students ask questions
during the lecture. It gives me immediate feedback on how students are
thinking, what they understand, and what is difficult for them. In addition,
asking questions helps students feel more comfortable during the lecture.
I consider the absence of questions as a first sign of a lack of understanding.

Sometimes I ask students questions
during my lecture. This stimulates active thinking and develops intuition.
Moreover, it is much easier to remember an answer you have to think
about rather than rote knowledge. Also I like to spend time with students
in an informal atmosphere, whether it is a coffeehouse or a hiking
trip. Occasionally, in such unofficial activities some students may
discuss their concerns more freely.
How can I improve my teaching?
Feedback from both students
and colleagues plays an important role in teaching improvement. In the
middle of the term I ask Students to complete a short questionnaire
on how to make my lectures and assignments better, which aspects of
my teaching are strong and which need improvement. From timetotime
I invite my mentors to my lectures and ask them for a feedback on how
to improve my teaching.
>
continue reading
Tests, quizzes, and exams are equally
important for both learning and feedback. The results of examinations
help me to understand which parts of the course are too difficult,
and which concepts are still too fuzzy. This understanding allows
me to improve my teaching for next term.
When I teach mathematics, do
I teach just mathematics?
I always keep in mind
that by no means will all of my Students be professional mathematicians
or engineers. This leads to a natural question: what benefits from
my course can my Students get for their future life?
>
continue reading
Mathematics adjusts our minds. Learning
mathematics develops logical, creative, and abstract thinking. There
is no lie in mathematics and this teaches us to be honest. Mathematical
complexity and beauty nurses our spirit. I believe that even if many
formulas, theorems, and proofs are forgotten with time, my Students
will still have very useful skills for the rest of their lives.
