This document discusses classroom assessment techniques (CATs) for measuring student learning. It introduces CATs and explains that they can be used formatively throughout a course or summatively at the end to assess student understanding and provide feedback. Various CAT examples are presented, such as concept tests, surveys, and rubrics. Bloom's Taxonomy is also described as a way to classify cognitive abilities from simple to complex. The document encourages exploring different CATs and matching them to specific course goals to identify the most effective assessment strategies.
