Development and Implementation of Augmented Reality-Based Card Game Learning Media with Environmental Literacy in Improving Students' Understanding of Carbon Compounds

The lack of knowledge integration about the learning environment is one of the causes of the low environmental awareness. The purpose of this study was to develop learning media for carbon compounds based on augmented reality and environmental literacy and to find out student learning outcomes after using media, students' perceptions of the media, and their environmental insight. This research is a research and development (R&D) research by following the ADDIE model. One group pre-test post-test research design was used to examine the effect of using the media. The research instruments were multiple choice test, questionnaires, and interviews which were developed independently and tested for validity & reliability. The analysis technique was the paired sample t-test and content analysis. The results of this study showed that the learning media was very eligible with a validation score reaching 88.1%. The result of the implementation of the final product of ChemiCa shows that there is an impact of using media on student learning outcomes (Sig. 0.000<0.05). Students' perception of the media are very good, learning media can increase their understanding of carbon compounds concepts, as well as their motivation to learn chemistry. This study implies that teachers can use augmented reality-based card game as a supplementary learning media to improve students’ understanding of others relevant chemistry concepts and their environment literacy.
