The present study showed that the performance of the weekly quiz group was significantly better than that of the control group. Along the same line, Geist and Soehren (1997) and Ballard and Johnson (2004) found evidence in favor of weekly quizzes compared with no quiz indicating that weekly quizzes enhance students‘ performance. The finding of the present study is also consistent with studies such as Martin and Srikameswaran (1974), Graham (1999) and Kamuche (2005), who confirmed that students who received weekly quizzes outscored students who received no quiz during the course.
