I'd agree in principle with what you are getting at in reference to "grade-grubbers". There are slackers out there just interested in doing enough to get by. However, too many people automatically associate that attitude with bad grades. I've never gotten really good grades in any of the classwork I've done and yet I've probably gotten more out of the classes than the average person. Fortunately, I've been in the business long enough to prove I'm no slacker. > >At a homecoming a few years later, I found out that a few people in my > >class who had graduated with a 4.0 in comp sci were having trouble in > >their jobs maintaining COBOL code for accounting/insurance type > >companies becasue they didn't know how to apply their theory to real > >world situations. > > The probably didn't understand the theory either, but were able to memorize > enough bullet points to pass the exams. This reflects poorly on your > instution. Actually, they were brilliant with theory. The one individual I'm thinking of was able to take the CompSci GRE and score in the upper 75%, but couldn't figure out how to format a report of an amortization table without help. The point I'm trying to make is that all theory and no practice is detrimental to the average student and tends to skew the grading curve all over the place. Someone who has trouble with something as simple as formatting output should not graduate with a 4.0 GPA. > >But you can teach the fundamentals in a few weeks, rather than in the > >two semesters they currently waste. > > I disagree strongly.

Everyone in my classes complained about the slow pace. We spent several days studying why Quicksort works as fast as it does. This after spending a few weeks on binary trees and how to search, sort and balance them. It seems to me that we could spend about a day on the theory of binary trees, spend the next day on the sorting and balancing algorithms and move on to one day looking at the various sorting algorithms. College students are not stupid. They do not need to rehash the basics like they were learining arithmetic in grade school. If I were designing a CompSci program at a college, I would make the intro classes available to those who need the "remedial" help. Most students who enter college with the intention of studying computer science have already had some exposure to it, much like most math students have already had pre-calc. There is no reason freshmen couldn't start studying algorithm design first semester. (unless, of course, they hadn't had the exposure, but that's what the "remedial" courses are for.) Once the basics of algorithm and data structure were taught in the fall, the spring would be dedicated to teaching basic programming methods. These would include using debuggers, performing peer reviews, constructing functional tests of the software, etc. After that, students would be ready to tackle higher level stuff. (And pardon my arrogant opinion, but if they can't handle basic algorithm design and programming methods, they have no business trying to be programmers.) > >If students spent more time learning how to solve real problems, they would > >be able to pick up the theory much faster. > > I don't believe this at all.

Teach someone how to solve problems in general, then show them the specifics of the field and they can apply their fundamental problem solving ability to that field. Electrical engineers can combine thousands if not millions of different components into electrical systems governed by very complex differential equations. Why then is it that professors can teach them how to do it effectively yet you claim the computer science students couldn't learn how to combine software packages together?

I agree that technical manuals are a good source of information for professionals wanting to expand their skills. Personally, I devour manuals left and right. I'm always learning something new and most of my information comes from the technical manuals. However, I disagree that technical manuals serve a usefull purpose for _most_ college students. They simply do not have the experience to make use of manuals. -- Voicing my own opinion, not speaking as a company representative... Roy A.
