21st century learning presents chemistry teachers with new challenges in teaching abstract chemistry concepts. The use of science and technology in learning media can increase the effectiveness and efficiency of the learning process. To explain abstract chemical concepts, one needs media capable of visualizing these abstract chemical concepts. Augmented reality (AR) is one way to overcome this. When developing a medium, it is very important to test the validity of the medium to determine the feasibility of the medium. Therefore, this study aims to test the validity of the Android-based AR media that was developed. The validation was carried out by 4 education practitioners as experts and 13 students participated as respondents. The instrument used is a questionnaire with a Likert scale. The data obtained were analyzed quantitatively with the Rasch model using the facet software. The results of the analysis show that the Exact Agreements are 41.1% and the Expected Agreements are 42.2%. The most difficult aspect to achieve is the media design, while the easiest aspect to achieve is the profit aspect. Based on this assessment, in the development of augmented reality media, it is necessary to pay attention to display aspects and 3D objects suitable for viewing a material so that it is easier for users. to understand the material.
Teaching abstract chemistry concepts is a challenge for chemistry teachers. Technology-based media is needed to visualize abstract chemical concepts, especially micro representations. Augmented Reality (AR) technology is one way to deal with this problem. The validity of the developed AR media is essential. Therefore, this study aims to test the validity of Android-based augmented reality media that has been developed. The Delphi technique was used in this study to obtain the data of validity. A total of 6 experts and 19 students participated as respondents. The data obtained were analyzed quantitatively with the Rasch model using facet software. The analysis results show that the correct agreement is 53.9%, and the expected agreement is 52.7%. The most difficult aspect of achieving is understanding the material, while the easiest aspect to achieve is using sentences. Based on the assessment, augmented reality media needs to pay attention to the appropriate display aspect to make it easier for users to understand the material and provide information on each augmented reality display.
In chemistry lessons, submicroscopic representations are difficult to understand. It takes visualization of atoms and molecules to understand submicroscopic representations. Augmented Reality (AR) is becoming a promising medium for visualizing atoms and molecules. Therefore, this study aims to investigate the effect of AR media on students’ understanding of submicroscopic representations in covalent bonding and molecular shapes topic. Qualitative research was used in this study. The dimensions investigated are the prediction rule of submicroscopic; quality of image submicroscopic and Alternate between macro and relate submicroscopic model. Respondents in this study were 30 students from a high school in Boyolali, Central Java. The instrument used is a test in the form of three questions related to the dimensions to be tested. The results of this study indicate that students are able to understand the submicroscopic level and the relationship between levels of multiple chemical representations using the developed Android-based Augmented Reality learning media.
