Students were given a pre-test and post-test during a unit on World War II. I preferred using the post-test as a formative assessment, giving students feedback about two-three days leading up to a final unit exam. I practiced charting and analyzing the data and using that knowledge to inform my writing for the review and test. Although the average grade on the post-test was 67.5%, the class had a 82.7% average on the actual exam.
