A simple easy way to better understand test scores (wow this is easy)

I just watched this video, and wow, it was surprising to me that I had never thought of this before. You can click on the video above to watch it or the link, here, and take a look at it in another window or tab. The video was created by educator Jennifer Gonsalez, and can be found on here you tube channel "Cult of Pedagogy", as well as many other educational videos meant for teachers.

This video highlights an easy was to get more meaning from your students test score. All you do is, instead of merely grading each test and moving on, keep track of the questions student get wrong. If you do this for all students then by the end you can find patterns that may be present in the missed questions, or questions all students got correct. This can highlight whether or not your question needs work, or if better questions are needed. It can also tell you if students are getting it.
