Teaching Philosophy

It is my belief that concentrating on the general ideas and the Big Picture without worrying about details will produce an individual who may be computer-literate but certainly not a productive computer professional. At the other extreme, an individual who masters the intricate details of a particular environment without being able to abstract will be obsolete as soon as the technology that underlies that environment becomes obsolete (which happens quickly in the computing field).

A blend of the two approaches is essential for confronting today's ever-changing state of this field which is nothing short of "evolution in action" with an "adapt or die" paradigm. Luckily, while technological details are changing rapidly and in a revolutionary manner, abstract concepts are evolving slowly and incrementally. Hence, by understanding how today's details fit in the general abstract scheme, we should be able to easily adapt and quickly comprehend tomorrow's technologies.

We can achieve this blend by observing two prime directives that tell us how to orchestrate the topics within a course and how to choreograph the discovery of concepts so that students can explore what can be rather than imitate what is. Here are simple yet enlightening depictions of the two directives:

• What is the relation between driving a car and the combustion engine? Do I need to known one in order to learn the other? And more to the point, why did you keep referring to spark plugs when you were showing me how to accelerate?


• Try as you may but I don't think your lectures will ever teach me how to skate. You have explained the techniques really well, even made me an expert in the physics of skating, but I still fall flat on my face every time I set foot in the rink!
