Abstract

This study aims to test the effect of e-magazine chemistry media on students' interest in learning buffer solution material. This research uses a quasi-experimental design. The data collection technique used was an interest questionnaire in the form of 20 statements that were tested for the validity of the items, with the results of all statements being valid and a reliability of 0.811, so the questionnaire has a very high level of reliability. The data analysis was done using a t-test at a sig value. (2-tailed) 0.05 parametric statistical test analysis through SPSS software version 25. The experimental class was given treatment using e-magazine chemistry media, and the control class used textbooks. The experimental class's average pre-test and post test scores were 56.18 and increased to 82, while the control class's scores were 55.26 and increased to 65.26. Based on the results of the study, it was shown that the use of e-magazine chemistry was influenced in learning buffer solution material in terms of the data analysis of 0.000. This study implies that e-magazine chemistry can improve students' interest.

Abstract

This study aims to develop and validate a test assessment design assisted by Augmented Reality to measure students’ multiple representation abilities. The development model used in this research is the 4D Model (Define, Design, Develop, and Disseminate). The research subjects were students of the Chemistry Education Study Program in the 2024/2025 academic year. The trial subjects consisted of 18 students. Product validation was carried out by three chemistry education experts. The data collection technique used was a questionnaire. The research instruments consisted of an expert validation questionnaire and a student response questionnaire. The data analysis technique employed a quantitative approach with predetermined criteria. The results showed that Validator 1 provided a score of 87.96%, Validator 2 92.59%, and Validator 3 84.26%. The results of the study show that the validation of the developed product obtained an average percentage of 88.27%, categorized as very valid. The small-scale trial gained an average percentage of 94.99%, classified as very practical. The medium-scale trial obtained an average percentage of 91.71%, also categorized as very practical. These findings indicate that the AR-assisted MBKM assessment for measuring students’ multiple representation skills is highly practical to use.
