[CLUE-Talk] Introduction to Computer Science Course

[Young, Ed]

Wow! Inspiring!

You're stepping out of the box, as they say these days, and that is very
admirable. It is also IMHO, sorely needed in CS cariculae, cariculum,
whatever. My suggestion may not fit for the particular class in mind, but it
should either be a class all by itself, or a large part of another course. 

My .02:
I believe that learning to decompose a problem in to simpler parts and
defining layers and components of the problem is one of the most important
skills in any problem solving undertaking. I don't believe that this is
realy well presented in many cariculae. Once a language is learned, many
think that jumping in a coding is the thing to do. Learning to first
understand the problem at hand and the solution's requirements are too often
disregarded as obvious or implicit. 

1. I think excercises in discussing increasingly complex problems and
identifying what constitutes a solution to that problem is an extremely
valuable skill, and possibly more important than being able to write an
entire grammar in one obfuscated "for" loop. For simple problems, hacking
out something that works if fine. For more complicated problems things have
to be better understood. Both to reach a solution, and to ensure that the
implementation is maintainable if things change. 

2. Once the problem is well defined and understood, and the solution's
requirements equaly well defined and understood, then learning how to
simplify the problem into it's layers and components makes the problem more
manageable. Defining the layers boundaries, also makes the problem more
clear and easier to implement. It's also a good team excercise since the
parts can be distributed amongst a group, and the process can generate a
lively discussion. 

I wish this sort of thing went on in industry,more.

As a graduate of a CS engineering cariculum, I learned to program early. It
was much later that I learned to first understand the problem. (sorry if
that sounded a little too contrived)

Good Luck, 

Ed

>  - cyber-terrorism (national, individuals)
>  - Artificial Intelligence (including fuzzy logic, genetic algorithms)
>  - Artificial Life (Boids, development and applications)
>  - man-machine integration (direct-connect, muscular; optical)

>  - hardware ("Let's take the covers off these computers...")
>  - software (a little programming in Karel, Java, maybe HTML and Python)
