Is there really a need to kill another tree if CANVAS provides a medium for quizzes? In a quasi-experimental design, introductory stats students across two semesters (SP and FA ‘16) with two different instructors self-reported the number of hours spent studying for a common cumulative quiz. One group used e-quizzes, the second used paper quizzes. Results are as follows:
- Marginally significant differences in the number of hours spent studying past quizzes with e-quizzers reporting slightly more time (M=3.76 hours, SD=4.88) than paper quizzers (M=2.71, SD=2.83), t(158)=1.72, p<.09;
- E-quizzers had significantly higher final grades (M=84%) than paper quizzers (M=79%), t(158)=2.35, p<.05;
- Significant moderate, positive correlation between number of hours spent studying for the quiz using weekly quizzes and the cumulative quiz (r=.266, N=160, p<.01), even after controlling for instructor effect (r=.205, p<.01);
- No significant changes in self-reported number of hours spent studying from Spring ’16 to Fall ’16.
Recommendation: GO GREEN and the mean may rise to the occasion
