Assessment is tricky business. There are so many different options to use in trying to assess how much the students have learned. And I just have to say, that grading is not one of the favorite parts of being an instructor. I have been teaching for a long time. I have tried several different ways to assess the students in my courses. What I have found to have made the biggest impact on their learning of, and retention of, mathematics, has not been my change in how I assess, but how often I assess. It isn’t unusual, in mathematics, to have your pass rate fall within the (50-60)% range. After having assessed basically at the end of chapters, 16 years ago I switched to assessing every week in many of the courses I teach. These are major assessments not just little quizzes. After this change I noticed a pass rate that was 20 to 35 percentage points higher than before. Here is an example, my college algebra course went from 55% to 80% pass rates on average with just this simple change. I’ve tried collecting Homework, daily quizzes, collaborative activities, large group projects, working at the board, etc. and none of those had the impact that this did. The biggest change wasn’t necessarily that the students were learning more but that more students were learning. The big change I saw was that the withdraw rate went from around 40% to 10%. I don’t know if this will happen in every subject or every different course within a subject area but I have seen it work for all of the courses I teach (intermediate algebra, college algebra, pre-calculus, and calculus 1 2 and 3). Give it a try if you haven’t ever.
