I traditionally assess whether students are reading using a 10-question multiple choice quiz per chapter. Students asked if they could use their notes and/or books. I allowed students in my MWF PSY230 course to use their notes/books for the quizzes while those in the T TH section were not allowed to do so. I kept track of how long it took students to complete the quizzes and their average quiz scores over a ten week period. Students who used their materials averaged 25 minutes to complete the quizzes while those that were not allowed to use their materials averaged only 12 minutes to complete the quizzes. Moreover, students that were not allowed to reference their notes/books scored significantly higher on quizzes (M=80.77%, SD=13.51) compared to those that were allowed to use such materials (M=68.48%, SD=15.23), t(63)=2.34, p<.05. Focus groups conducted at the end of the semester revealed that students who had access to notes/books became extremely reliant on the materials to look for the answers which took more time than they expected and strongly urged me to not let future classes user their books/notes on quizzes. I agree.
