College Board Kills AP Computer Science AB
jhealy1024 writes "The College Board recently announced it will be getting rid of the Advanced Placement Computer Science AB examination after May 2009. The 'A'-level exam will continue to be offered, though there is no word yet on what will become of the AB-level material (e.g., if it will be merged into A or just dropped). Many teachers of AP CS are upset about the move, as it seems the decision was made without consulting members of the CS teaching community. As one teacher put it: 'this is like telling the football coach next year is the last year you have a varsity team.'"
You don't need advanced skills to flip burgers.

Rhymes that keep their secrets will unfold behind the clouds.There upon the rainbow is the answer to a neverending story
I took computer science AB when I was in highschool and it was a great class if you looked past the god forsaken code project you had to modify that had something to do with fish. I learned all about algorithms, data structures and other important topics that I would not have gotten formal exposure to until, well, never because I didn't major in CS. One huge drawback is that it's taught in Java now, which is absolutely terrible for learning the fundamentals (I took it when it was C++)
What is the biggest shame is this course was hugely popular in my tech-oriented highschool: Like 50 people took the AB exam every year out of my class of 120 or so. While I understand TCB is trying to cut the cost of making unpopular exams, keeping computer science A is a joke because AB wasn't all that fast and A doesn't even count for credit at my university; It's basically just a waste of time.
CS instructors at the high school level will have much broader latitude in what they teach. You could go a vocational route (say, Rails), or a different theoretical route (say, The Little Schemer).
I also think it's possible that the contents of AB need to both go into A. It's been a long time since I took them both (1989), so things may be different, but my recollection is that the contents of A alone really weren't much beyond pragmatic familiarity with basic imperative programming, the kind of stuff that your basic "Teach Yourself X in Some Ridiculously Short Period of Time" book can actually teach you.
That said, if what they're doing has the effect of dropping the study of data structures and algorithms from the high school curriculum -- if dropping B really means there will be less CS in the classroom -- then this is a really poor move.
Tweet, tweet.
I suspect that this decision won't help the current paucity of valid Computer Science courses in high schools. I'm still annoyed by the number of Microsoft Office or HTML courses that get passed off as CS. On the other hand, I guess it's possible that this could encourage more people to take APCS A (as there would be no real two-year commitment as there can be now), which would be a good thing. Hopefully some of the AB material can be folded into the new A course, as it would be a pity to lose AP-level high school instruction on big-O algorithmic analysis and data structures.
I can understand the College Board wanting to concentrate their resources a bit more, but I still don't think that slashing the curriculum is the way to do it. Of course, maybe I'm biased -- my high school APCS courses were great and I don't think we got much of anything from the College Board in the way of support.
I took AP CS A and got a 3 on it. When I applied into college they told me I should take the introductory course because most people who got a 3 on the AP test and skipped it would fail the next step up.
I skipped it and the next step up was extremely easy. When I was writing my review of that class I told them I could have learned almost everything they taught me in that semester in a week.
Just goes to show what trash the grader was on the AP test. They probably thought all of my lower case 'j's were 'i's, and probably marked me down for declaring new variables anywhere but the beginning of the function. To put it in perspective, a 3 is supposed to be the same as a C in college, yet I went through college never getting a C in anything and getting predominately A's and B+s in most CS classes- even the ones with a 90% failure/drop-out rate.
Part of it is that the teacher of my AP class, a female cheerleading coach (no kidding), was a decent teacher and could get you to learn a concept like new data structures or pointers in 20 minutes.
I'm currently enrolled in AP Computer Science AB, and I can say without a doubt it has been one of the most useful classes I've taken up to this point. I'm frustrated and confused at this news. I suppose the upside is that fewer computer science courses will conform to the strict Java-only curriculum, allowing for educations in other programming languages besides Java, such as C/C++. On the other hand, it may just mean less material is taught in high school computer science courses. If I had to guess which is more likely, I'd have to go with the latter.
They also cut Italian, Latin literature, and French literature.
As a college teacher, I'm uncomfortable with the place that AP exams now occupy in our educational system. When I went to college, it was considered unusual to take AP exams, and nobody had ever heard of a GPA higher than 4.0. Now, with AP classes counting +1 on the GPA, Berkeley is turning away a sizable fraction of all students with 4.0 GPAs. In other words, you essentially can't get into the flagship schools of the UC system unless you have a lot of AP exams to puff up your grades. In one way this is good, because the old system encouraged kids not to take challenging coursework in high school. But a lot of rural and inner-city high schools don't offer AP courses, or don't offer more than one or two, or they offer them, but they're not at a high enough level to prepare you for the exams. There's something horribly wrong with a system of government that taxes working-class people in order to support public education, but effectively excludes their kids from getting the full benefit of the system they're supporting with their taxes.
Looking over the contents of the CS exams, I can't help getting the impression that this is vocational education masquerading as something more academic. It all seems to be focused on the OOP fad, and on being able to code in Java. Stacks and queues are only covered on the AB, not the A level!?!? The hardware part seems pretty lightweight, and there's virtually no theory AFAICT.
Find free books.
Having gone though several international high schools (located across Europe), they all offered CS A and AB.
When I finally took it (A, in Grade 11) it was taught as a combined A/AB class by the school's Director of Technology. It wasn't as formalized a most classes - we simply took over the computer lab and its whiteboards for our classroom - but it was small, intense, and with a smart group of people. We finished the AP spec about halfway through the year, so for the second half we just did a bunch of code projects, only one of which was the standard AP one (this was the year before they brought in the aforementioned god-awful fish tank project). Independently, when I went to (public) school in Canada, AP CS A was offered as well, with the usual caveat that the school board wouldn't pay the testing fees (but would teach a class on it).
If you say it's unavailable outside the US, you need to compare that against the availability of other AP classes - do you mean that the French national school board won't offer them, or that the American School in Paris won't?
Cue The Sun...
The article also mentions the possibility, in the context of the Italian course, of the program being continued if a sponsor could be found. Perhaps Mr. W. Gates and the other hi-tech moguls who are always bemoaning the lack of US workers, and crying for more H1 visas, could pony up a few bucks to support the CS course. I'm sure it would be chump change for Bill.
No, it's like telling the football coach that next year is the last year there will be trophies awarded at the championship game. They can still have a team, there just won't be an official ranking.
Of course the AP test credit is a lot of the value of the programme, so cancelling the test is a travesty, and might be a reason to cancel the course, especially if students spend their time taking other courses that award the credit they can use.
But if the teachers are making that kind of analogy, they shouldn't be teaching. Not even CS classes, because thinking with analogies is more important to programming than is instruction in language syntax. It's like a football team with a coach who's really just the second-string halfback.

In my high school, AP classes don't exist. I'm supposed to be going to the best high school in my school district... but we don't get AP classes. It's called the inner-city.
This is a signature. Bow to me.

A number of the tests are offered at different difficulties, including Computer Science with the A and AB levels, and Calculus with AB and BC levels.
The College Board has announced that they're dropping four tests, three language tests plus the AB CS class. Since it was short notice with little consultation, and the AB test was the only one with any content that would really be considered computer science (e.g. data structures), teachers are up in arms.
The broader issue is that primary and secondary education vary enormously in quality and funding over the US. This is partly because different states want to do it differently (good), and partly because education is funded almost entirely out of local property taxes, so rich areas have super-schools, and poor areas have lousy schools (bad). The cycle reinforces as rich people move to areas with good schools.
Thus the complaint that only rich high schools can afford to teach AP classes, and AP classes are necessary to get into the best universities.
Oh, and varsity: in American high school and college sports programs, the Varsity team for a sport is the best team, which represents the school in competition with other schools. So if you're not very good at football, you might still be able to play on the Junior Varsity team, but probably not for the the Varsity team. Teacher is claiming that AB-Test-Takers = Varsity CS Team.

Screw AP, here is how I got college credit early: Do well on your ACT (or SAT I guess, never had to take the SAT myself) to qualify for college substitution credits. Try to find out which courses at your local Community College will actually transfer to your preferred university. Apply with your high school and the CC to take those courses for high school credit. Upside: If you choose correctly, you probably only have community college classes two days a week, but only have to go to high school for half a day. Downside: You are probably going to school at night. If you don't pick the courses right, the best you can hope for on transferring credits is some sort of 1 credit in General Science 999999 which doesn't count towards credits for your degree...... (Seriously, I'm lucky I took a Fortran class in addition to my Object Oriented Programming class, since OOP turned out to be... Visual Basic)
Actually, it WAS Adam and Steve. that's what happens when you read a poor translation.
I have a friend who teaches an AP science class at a a local high school. The high school produces about half the National Merit scholars in the county despite the fact it's a tiny school of some 200 students. The science department has battled the humanities department for years over whether to keep AP courses or not. The humanities would just as soon see them gone.
A year ago, the science department almost gave in when the AP organization required each teacher to explain in detail how they met the AP curricula requirements. That added another teacher work day to an already harried schedule. She typically works late into the night grading work and the last thing she wanted to do was to spend an extra unpaid work day justifying her course to the AP organization. She figured it was enough that her average student AP score is 4.8 - the hell with how she does it.
Adding more steps to any program guarantees you'll lose some participants. Perhaps that's what the AP board intended with their new regs.

No, the College Board introduced the AP Audit because some of their members, the colleges, said that they were seeing too many students with AP classes on their records that were completely half-assed and not even college prep level. The kids took the exam and consistently failed because the teachers were not teaching the exam topics, but labeling regular history as "AP History, take the exam if you feel like".
This was troublesome for both kids and admissions counselors. They thought they were getting a college prep class and/or that they'd be able to score a 4 on the exam, and neither were true. Similarly, the college that admitted them thought that they were either not so smart for failing that AP exam or thought they had a much more rigorous high school career than they did.
It would appear they didn't even consult or even inform the group of people who prepare the curriculum and write the exams either. Clearly, they had already made up their mind to ditch it and didn't want to inconvenience themselves with a justification of it. Ah well, I guess AP/A will now tank, and districts will go "Hmmm, AP/A wasn't getting our kids any college advantage, and now there's just it to offer, so let's save ourselves some money and drop ComSci completely from our course offerings. After all, computers are expensive, where can you find teachers willing to do it etc etc blah blah." I guess the states or the federal government (yeah, it's not a realistic view) might want to take on setting up a decent 9-12th grade ComSci course sequence to make sure that ComSci teaching doesn't completely collapse in the US.

Actually, I don't think it is a big loss. Don't get me wrong. I think it is great that high schools prepare students by learning them some computer skills. However, things I see is that freshmen, in a computer science course, lack the basic skills. They seem to have almost no skills when it comes to math, physics or even general problem solving skills. Heck most freshman can't even spell. (And when they spell something wrong it's not even done in a consistent way). Something else. It seems that students are taught things either wrong, out of context, or in the wrong context. That is really an obstacle, for the student AND a teacher in college. You won't believe how often the phrase "Well, than your computer science teacher in HS had it wrong" sentence is used in the first year in college. So if I would be asked, and actually that question was asked at the ACM SIGCSE meetings this spring, what it is students should be taught the answer would be: Math, geometry, how the solve 'logic' problems etc etc. I do think it is a good idea to teach HS students computer skills, focusing on that would help quite a bit. I don't mind that students are shown some simple programming 'things'. However you won't believe how many students do know how to wrongly create all kinds of code but are not able to copy a zip file from one drive to another and extract it in such a way that it results in an organized way of storing their lab and project work. The wrong 'programming' techniques we can usually fix but the lack of math, logic, geometry, science/physics etc is something that keeps haunting them all the way through college.
