This study implemented an online peer assessment learning module to help 36 college students with the major of pre-school education to develop science activities for future instruction. Each student was asked to submit a science activity project for pre-school children, and then experienced three rounds of peer assessment. The effects of the online peer assessment module on student learning were examined, and the role of Scientific Epistemological Views (SEVs) in the learning process was carefully investigated. This study found that student peers displayed valid scoring that was consistent with an expert's marks. Through the online peer assessment, the students could enhance the design of science activities for future instruction; for instance, the science activities became more creative, science-embedded, feasible and more suitable for the developmental stage of pre-school children. More importantly, students with more sophisticated (constructivist-oriented) SEVs tended to progress significantly more for designing science activities with more fun, higher creativity and greater relevancy to scientific knowledge, implying that learners with constructivist-oriented SEVs might benefit more from the online peer assessment learning process. These students also tended to offer more feedback to their peers, and much of the peer feedback provided by these students was categorized as guiding or helping peers to carefully appraise and plan their science activity projects. This study finally suggested that an appropriate understanding regarding the constructivist epistemology may be a prerequisite for utilizing peer assessment learning activities in science education.
