Teaching Philosophy
Teaching/Learning is a two-way exchange of
knowledge and a close interaction between a
teacher and a student
How do we learn? An old proverb captures the
essence of learning process - I hear and I forget;
I see and I remember; I do and I understand.
Question everything; Rationalize your
answers.

 In this course, emphasis is placed on deep
understanding and learning.
 Understanding of basic concepts and problem
solving skills will be promoted.
 Assessment will be based on demonstrated
ability to apply basic concepts to effectively solve
a problem using the language of engineers 
mathematics.
On learning and securing good marks
14
CODE OF CONDUCT
 Turn off your cell phone when you enter the
classroom
 Keep the internal discussions to a minimum
 Background chattering noise is distracting for the
instructor and eventually to classmates
 If you have something interesting to share, share it
with the whole class
 If you are sleepy, your bed may provide a
better environment for rest than the classroom
chair
15
WHAT YOU CAN EXPECT OF ME
 Be committed to help you understand and
master the course material
 Be available for out of class assistance
 Provide competent teaching
 Treat each question or concern seriously and
answer these to the best of my ability
 Treat each of you with courtesy and respect
16
WHAT I EXPECT OF YOU
General Expectations
 Ask question whenever something is not clear to
you
 Help each other understand the course material
 Perform all assigned reading on time
 Arrive on-time for class
 Be courteous to each other and to me
 Provide me with feedback/suggestion  on how
the course and my delivery can be improved
