Analysis of student's mental model through representation chemistry textbooks based on augmented reality

The mental reconstruction model of students is essential to see the progress and difficulties of students in understanding chemical material, especially at the level of macroscopic, submicroscopic, and symbolic representations. This study aims 1) to see how the influence of Augmented Reality (AR) based learning media with the concept of representation, 2) to see the validity, practicality and effectiveness of the development of augmented reality-based representational chemistry textbooks, and 3) to analyze the mental models of students. The research method used is a literature study (literature study) with qualitative and quantitative approaches. The data collection technique used is the non-participant observation technique by reviewing and examining various research results related to AR-based learning media and the concept of chemical representation. The results of the study with the context of literature studies showed that AR-based learning media (teaching materials) with the concept of representation could increase the reasoning power and understanding of students in learning chemistry. The impact students can interpret more deeply so that their mental models can be reconstructed into scientific concepts. The conclusion that can be taken was that learning chemistry with the idea of representation through teaching materials based on Augmented Reality (AR) could be used as the primary reference in learning chemistry. Besides, the concept also changes the mindset and mental attitude of students as the generation of the Indonesian Nation, where improvements in mood and mentality from an early age have the potential to foster the readiness and resistance of students. That is, the application of this idea shows that natural science (chemistry) has a very vital role in the progress of the Nation, especially towards high-quality education according to the SDGs indicators.
