I have been using standards-based grading for calculus I and calculus III this semester. In short, I quiz the students on questions from roughly 12 “topics.” These “topics” are the mechanical skills that students need to know to do calculus (e.g. “take derivatives,” “compute integrals,” “find tangent lines”). Each quiz question is tied to a topic, and labelled as such. Students need to get four questions correct on each topic by the end of the semester.
Dana Ernst made me realize that I can create video solutions for these. This has the dual effect of
- I can give the students more worked examples without taking up class time. Also, these worked examples are very relevant to the students, since they just thought about the problems.
- I can save time grading. I comment a lot less, since students can see how to do things correctly if they are just a little off (if the student completely misses the problem, I will still comment).
I post the solutions to my course management software (Moodle); I organize them by topic. So if a student has trouble finding tangent lines, they can simply go to that section of the Moodle page to see several worked examples in the same place.
