This study developed a wearable mixed reality (MR)-based mobile learning system and applied it to museum learning activities to explore whether the proposed system can effectively improve university students' learning outcomes, situational interest, and cognitive load. Four museums were selected as the informal learning sites, and 64 university students were randomly divided into the experimental group (using the wearable MR-based mobile learning system) and the control group (using the conventional mobile learning system). The results show that in the retention and comprehension dimensions of the learning outcome, the experimental group has significantly better learning performance than the control group. The experimental group showed improvements in almost all dimensions of situational interest, except for the challenge dimension, while their extraneous cognitive load was reduced. Furthermore, this study found that the proposed system has a positive influence on museum learning in higher education, and has good potential for improving the conventional mobile learning system and enhancing students' learning performance. The findings of this study can provide a reference for future research on the possibilities of using wearable devices for museum education.

This study developed a VR-based mobile learning system to simulate the natural environment of a geopark for university students to learn geological knowledge. This learning method used a Google cardboard equipped with smartphones, where students can watch stereoscopic scenes and experience virtual environments as if visiting the geopark. In order to evaluate the learning effectiveness of the proposed system, we collected the learning outcomes, learning motivation, and cognitive load of students before and after the learning activity. The results indicated that students had significantly better learning achievement in their comprehension ability and learning motivation after using the proposed system. Therefore, it can be inferred that the VR-based mobile learning system not only helps students restructure knowledge and improves their comprehension skills but also enhances their learning motivation tendencies. In addition, the results showed that the students did not have high intrinsic and extraneous cognitive loads but had a high germane cognitive load. This finding implies that the proposed system can promote students' learning without overloading their working memories.
