Hi Everyone,
I was working as a data analyst trying to find ways to improve student success. As a STEM major (Biochemistry, Physics, Math, Stats, Engineering) I looked into how well a student in a class, say Algebra 1, affects their grade in Algebra 2. For most colleges and universities, a student that gets a "C" in CLASS101 has met the pre-req for CLASS102.
What percentage of students taking a class should be able to pass it the first time they take it? ( I found it's between 50% and 70%)
If a student fails a class, what percentage of them retake it? ( I found it's between 30% and 50%)
If they retake the class, should they do better or worse the 2nd (or more) time around? (Worse)
Suppose that a student gets a "C" in Algebra 1. What is an acceptable percentage of these students that can take Algebra 2 and "Pass" it? Here, by "Pass", I mean get a grade between A+ to C. ( I found it's between 30% and 45%)
Suppose that a student gets a B+, B or B-, in Algebra 1. What percentage of these students should "Pass" Algebra 2? ( I found it's between 60% and 70%)
Suppose that a student places into Algebra 2 and they did not take Algebra 1 at your college/university. Should these students do better/worse/same as the students that took Algebra 1 at your college/university? (They do better than "C" students)
If we assume that students need to take College Algebra to graduate, what percentage of students that start there college careers in Algebra 1 or Algebra 2 should make it to into College Algebra (Not talking about passing, just taking it)? (5% to 15% or 1,555 of 14,110 of Algebra 1 students make it to College Algebra. 17% to 31% or 2,721 of 11,010 make it from Algebra 2 to College Algebra)
If students need to take at least Calc 1, if not the Calculus sequence, to become a STEM major, what percentage of students starting in Algebra 1, Algebra 2, College Algebra and Pre-Calc should make it there? ( My data says those rates are 2%, 5% to 6%, 2.5% to 15% and 32% to 42%)
Just think for a moment. If only 2% of Algebra 1 (the most popular math course) students make it to Calc 1, and 5% of Algebra 2 (2nd most popular math class) students make it to Calc 1, what does that say about the math pipeline? and graduating from college in general? and the ability to get more STEM majors. Keep in mind too that the majority of students in these classes come from disadvantaged schools (like Detroit Public Schools).
I actually have data that answers what IS happening at a local (to me) college and university. I know what I think these pass rates should be. I want to see what others think.
