- 11. 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. 11

- 13. 13 • 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. 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. 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. 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
