| Summary: | 碩士 === 國立雲林科技大學 === 資訊管理系 === 105 === Nowadays, the use of 3D virtual world is more and more widespread. The environment provides a deeper level of interaction in the field of education. Leaners may be confused at the 3D application features, and multiple views may interrupt learning at the same time. It is difficult for students to understand the conception of the chemistry. Thus, students need to learn the idea through experiments, but real experiments cost higher. This research investigate the virtual chemistry laboratory affect the academic achievement. The survey was done by the students who used the virtual lab before and was analyze through Prtial Least Squares. The results indicated that experiential learning affect academic achievement positively. Therefore, the reseach randomly selected 70 students as the experiment units to validate students’ academic achievement. This experiment took nine weeks on all learning activities and designed as four phases. The results showed that experiential learning significantly affect the learning motivation and the academic achievement. The cognitive load affect learning motivation negatively and self-efficacy affect the learning motivation positively. The virtual chemistry laboratory affects the academic achievement positively. Students who used virtual lab before more understand the chemical concepts. Moreover, virtual lab promotes. students’ motivation on chemistry.
