Abstract:
As the use of augmented reality (AR) in educational settings grows, it becomes increasingly important to understand how to use AR in classrooms. Here, we present an AR learning environment that we designed for teaching an organic chemistry reaction mechanism in high school chemistry classes. This new environment was tested in six tenth-grade chemistry classes (upper secondary) taught by five different teachers in three different schools over the course of five months and evaluated for effectiveness. Students completed knowledge tests before and after they used the AR learning environment to test their learning gain, and surveys to measure their acceptance of the technology, the cognitive load they experienced, and their attitude toward the use of AR to learn the mechanism for radical substitution. Analysis shows that the knowledge posttest scores were significantly higher than the pretest scores (p < 0.001), with a large effect size (r = 0.8). Student responses showed acceptance of the technology, experience of low extraneous cognitive load, and a positive attitude toward the use of AR to learn this reaction mechanism. These findings indicate that this AR learning environment can be used to teach the mechanism of radical substitution to tenth-grade students in introductory high school chemistry courses.
