Designing an Augmented Reality Application to Assist Middle-school Student Learning Three-Dimensional Views
Spatial ability is one of the essential skills for every individual. Previous research has indicated that learning spatial geometry is an effective way to cultivate students' spatial ability. However, students usually did not learn the skill well due to lack of effective instructional tools. Augmented reality (AR) with the ability to integrate virtual information onto real-world, is considered an effective tool to help students develop their spatial abilities. In this study, we developed an AR tool to assist students in learning three-dimensional-views concepts in spatial geometry. This AR application aimed to help students imagine the three-dimensional-views of an object and vice versa, mentally constructed the object from its three-dimensional-views. A quasi-experimental research design was conducted in a middle school to evaluate the effectiveness of the tool. Twenty-eight seventh-grade students were assigned to the experimental group, using the AR application with wooden blocks for building objects, while 27 seventh-grade students served as the control group used wooden blocks only. Data from the final achievement test, attitude questionnaire, and group interviews were collected for further analysis. Our findings showed that there were no significant differences between the two groups in students’ learning achievements and motivations. In addition, both groups of students had positive attitudes on the usefulness and ease of use of their learning tools, however, the control group showed more ease of use than the experimental group. We suggested further research should revise the AR application to improve its usability in scanning objects and reduce students' cognitive load while using the tool in learning.
