A good point. The students place themselves in the courses. Many of my students place themselves there due to whether it fits in their schedules or not. Additionally, many of the freshmen students don't even know what they have chosen. This is another area worthy of study. I would like to study this where the students are randomly placed, but there are problems when you take choice away from the students. this study includes the entire population of students who have taken Calculus&Mathematica at the University of Illinois since it's inception. Some may or may not have been subjected to propaganda,either positive or negative. Students high school records were only used as a basis of admission to the university. ACT score were checked to see if one group was higher than the other for students in C&M or traditional calculus. This data only reflects the trend for students in this class at this university.
Thank you very much for your comments. I will keep these questions in mind for future analysis.
