Abstract

This study aimed to analyze the effect of using digital chemistry learning media on students' concept understanding in chemistry learning. The method used is a literature review with a qualitative descriptive approach. Data were obtained from five scientific articles published between 2019 and 2025, focusing on the use of digital media such as learning videos, interactive multimedia, augmented reality, and online evaluation platforms. The results of the study show that the use of digital media can improve students' concept understanding of chemical materials, especially on abstract concepts. Learning videos and interactive multimedia help visualize concepts, increase learning motivation, and support information retention. The use of augmented reality also provides a more interactive and contextual learning experience, and supports the improvement of students' digital literacy. The conclusion of this study states that digital learning media has great potential in creating more meaningful and in-depth chemistry learning, but it needs to be balanced with infrastructure readiness and teacher competency development in integrating technology effectively.

Abstract

This study aimed to investigate the effect of applying the Project Based Learning (PjBL) model assisted by animated videos on students’ learning outcomes in atomic structure material at Grade X of SMA Negeri 3 Pematangsiantar. The research employed a quasi-experimental design with a pretest-posttest control group. The participants consisted of two classes: the experimental class, which received instruction using PjBL assisted by animated videos, and the control class, which received conventional instruction. The research instrument was a learning achievement test administered before and after the treatment. Data were analyzed using a t-test and N-Gain calculation. The results indicated that the average pretest scores of both classes were relatively the same. After the learning intervention, the average posttest score of the experimental class increased significantly compared to the control class. The average N-Gain score of the experimental class was in the medium/high category, while that of the control class was in the low/medium category. The t-test result showed a significance value of p < 0.05, indicating a significant difference between the two classes. It can be concluded that the implementation of the Project Based Learning model assisted by animated videos has a positive effect on improving students’ learning outcomes in atomic structure material.
