I often agree with the identification of issues below, and sometimes with the opinions, but I think there are some factual errors and omissions. Details within...

I am not sure what this means or if it is meant as a quote from the AP site, but the usual situation is that students get credit for a specific course at the college of their choice, and that satisfies any prerequisites asking for that course. The one thing they do not get is a grade. Or, it's not A, B, C etc., just a pass. > Herein lies the catch: a student who may have taken AP Statistics in > high school may not see a statistics class in college whatsoever.

I think we need data to draw a conclusion here. Some of the kids in AP Stats. would not have taken stats. in college anyway. Many take it anyway because not everyone gets a great score on the AP exam. Those students often report the college course is much easier, and they do well in it. I know that some kids take more stats. and even major in stats. as a result of taking the AP course. I do not have numbers for any of these but I don't think we should jump to conclusions without them. > Having my kid going through AP Calculus now as a high school student, > and knowing who is going to teach AP Statistics, I have very mixed > feelings about these courses.

Actually the people with math. degrees are the ones who lacked the people skills to become good teachers;-) (Disclaimer: I have a BS in mathematics from MIT.) Seriously, there are people who WANT to teach but have no interest in research. We have little chance of cooperating with those people if we begin by insulting them. The target course for AP Statistics is typically taught in a mathematics department by a mathematician with 1 plus or minus one course in statistics in their background, i.e., the same stats. training as the typical AP teacher. That professor typically chooses a cookbook textbook and focusses on hand calculations with toy data (actually, batches of made up numbers). AP uses quality textbooks by highly qualified authors. The exam is written by simialr people. I challenge any college stats. instructor to administer an old AP exam to one of their own classes and compare the results to those of the AP students. > The uptake of the American Statistical Association resources for AP > Stat instructors appears to have been dismal; I was not able to > convince the teachers of AP Stat in our local schools to use these > resources, and they instead rely on the pre-canned solutions by the > commercial publishers. Generally high school math. teachers are EXTEMELY tired of college folks looking down their noses at them and telling them what to do. We will have to bend over backwards to avoid that if we want to influence them. The master of that skill in my opinion was Dick Sheaffer, past president of ASA and (IMHO) the father of AP Stats. AND coauthor of many resources teachers DO use. That said, I am disappointed at how little interest high school teachers show in learning content beyond what they have to teach tomorrow. This does lead to shallow understanding. OTOH, I spent most of my working career in college mathematics departments, and I find high school teachers MUCH more open to learning more about content and pedagogy than college mathematicians teaching statistics.

I agree with most of this except that the CB does nothing I know of to promote Minitab and from what I can see in the online AP Stats. community more folks are using R than Minitab. Generally the teachers prefer EDUCATIONAL software over anything used by professionals. So StatCrunch is very popular as are online applets, and a significant number use Fathom. In my own career I have been in and out of contact with k-12 teachers. Early on the math. teachers were the ones using and teaching BASIC. When I returned years later computers were being used mainly for business courses and writing term papers and many math. teachers were quite computer-phobic. The future teachers in my stats. classes wanted to do everything on their TI and many resisted using Minitab. But not all. I do not think there is any hope of converting ALL AP teachers to R. But a significant number are already using it, and those folks are often leaders in the AP community. What I think we can do is to make it as easy as possible for any AP teachers who would LIKE to explore R to do so. > I don't have any solutions, I am just reporting the symptoms.
