A need analysis for the development of augmented reality based-geometry teaching instruments in junior high schools

Previous studies have shown that augmented reality (AR) is an interactive teaching media that can improve students' learning motivation and spatial ability. Many studies have discussed AR technology and GeoGebra App but there are no previous studies on developing and using GeoGebra AR-based teaching instruments to improve students' spatial abilities in mathematics. The purpose of this study to develop valid and practical GeoGebra AR-based teaching instruments on geometry and used the Plomp model. This paper only reports the findings on the preliminary research. The research participants were three vice-principals of curriculum, three mathematics teachers and six-year 8 students who were randomly selected. The data were collected by administering questionnaires, interviews, and observations, and then analyzed descriptively. The result of this study indicated that the mathematics learning process on geometry topics in years 8 could be improved through GeoGebra AR-based teaching instruments. Moreover, students' abilities were sufficient to use it. In conclusion, students and teachers need GeoGebra AR-based teaching instruments in geometry learning. The results of this study can be used as theoretical and empirical references for the next stage of development.
