Integration of the peer assessment approach with a virtual reality design system for learning earth science

This study developed a peer assessment approach incorporated into virtual reality (VR) design activities for fifth-grade students to learn knowledge about a geological park in their natural science course. All the students were asked to design a VR project after they had learned the geological knowledge, so as to raise their environmental awareness and cultivate their earth science knowledge. In order to evaluate the learning performance and perceptions of students in two groups, one with peer assessment and the other with teacher feedback, we collected the learning achievements, learning motivation, self-efficacy, critical thinking tendency, creativity tendency, and cognitive load of learners before and after the activities. The results indicated that students performing the VR design activity with the peer assessment learning approach had higher learning effectiveness. They also had higher self-efficacy and critical thinking tendencies than those using the VR design system with conventional teacher feedback. In other words, the peer assessment approach not only improves students’ learning achievement, but also enhances their self-efficacy and critical thinking tendencies.
