Abstract
Pre-lecture reading quizzes, or Readiness Assessment Tests (RATs), improve college students’ exam performance; however, implementing RATs requires instructor resources. This study compared accuracy versus credit/no credit grading criteria on exam scores, participation, and attendance in two sections of a college course using a nonequivalent control group design. Students in the credit/no credit group spent less time on RATs and performed poorer on both RATs and unit exams across the semester compared with students who were required to respond accurately on RATs. We did not find significant differences between groups on attendance or participation. Although grading for completion rather than accuracy may be less intensive for instructors, our findings suggest this choice may decrease the benefits of RATs for students.
