A Virtual Experiment for Learning the Principle of Daniell Cell Based on Augmented Reality

Chemistry is a science emphasizing both theory and experimentation. After learning the theoretical knowledge, experimental operation can help students understand chemical concepts transform them into practical knowledge. Considering safety issue lack of teaching time equipment, some teachers often choose to demonstrate an experiment instead letting conduct it by themselves. This may affect their motivation as well construction hands-on skills. study combined augmented reality (AR) technology with operating principle Daniell cell develop virtual for application in high school chemistry courses. Students using mobile devices selecting required equipment materials from deck cards set up environment. In experiment, use galvanometer measure current after mounting salt bridge on beakers containing zinc sulfate copper solutions. They also see change molecular structures movement electrons ions during redox reactions important An empirical research has been performed, analytical results show that real could improve students’ achievement, but former was more effective low-achievement because they explore autonomously enhance cognition observing submicroscopic view reactions. The post-test average score group (41.60) significantly higher than control (27.67). Questionnaire reveal most were satisfied contents, user interface, motivation, system reality, practicality satisfaction 3.98 out 5. experiments not limited or space. only need download (APP) software print AR practice at home, so suitable large-scale promotion rural areas.
