While the learning potential of student-constructed tests (SCT) for the promotion of knowledge integration and elaboration has been suggested, its learning effects warrant further empirical examination. A single-group pretest-posttest experimental research design was adopted to examine if the performance of students exposed to the SCT condition was enhanced, while a control-group pretest-posttest experimental research design was used to examine the comparative effects of SCT and student generated questions (SQG) on science learning. An online learning system was adopted to support the associated activities involved in the respective groups. The results from the paired t-tests found significant differences in student attitudes toward science and science learning motivation. Yet, no significant differences were found in student use of cognitive and metacognitive strategies. Furthermore, SCT induced the majority of the participants into self-regulatory behavior. Finally, the results from the ANCOVA found no significant differences in any of the examined variables between the SQG and SCT groups. Suggestions for instructional implementations and future study are provided.
