Abstract

Representations in chemistry are essential for supporting students' understanding of abstract concepts such as redox reactions and voltaic cells. However, many students experience difficulties due to the lack of integration among macroscopic, submicroscopic, and symbolic levels of representation in textbooks. This study aimed to evaluate the quality and integration of visual representations related to voltaic cells in general chemistry textbooks widely used in Indonesian undergraduate programs. A descriptive qualitative content analysis approach was employed using an evaluation rubric developed by Gkitzia, which includes five criteria: type of representation, interpretation of surface features, relatedness to text, existence and clarity of captions, and the degree of correlation between components in multiple representations. Data were collected from five textbooks selected through purposive sampling and analyzed both qualitatively and quantitatively. The results showed that while most textbooks present macroscopic and symbolic representations adequately, submicroscopic levels are often lacking or fragmented. Common issues identified include insufficient labeling, missing or problematic captions, and weak text-image integration. Only a few textbooks provide well-developed hybrid representations. The study concludes that visual representations in textbooks still need significant improvement to support conceptual understanding. These findings provide insights for chemistry educators and textbook developers to design more pedagogically effective materials.

Abstract

Intertextuality refers to the process of understanding a context by exploring and connecting relationships between different texts or representations. In chemistry education, intertextuality serves as a communication bridge that links the three levels of chemical representation: macroscopic, submicroscopic, and symbolic. This study aims to enhance students' understanding of Molecular Geometry Concepts through Intertextual-based Learning with 3D- visualization. The research employed a quantitative approach with a one-group pretest-posttest design. Participants were selected using purposive sampling from undergraduate chemistry education students. The study involved 26 first-year students majoring in chemistry education who were taking a general chemistry course. Data were collected using student worksheets and pretest-posttest assessments. The data analysis included t-paired test for parametric statistic and evaluating student responses related to learning outcomes. Analysis of the t-paired test results shows that there is a significant difference in the pretest and posttest scores with a significance value of (p> α0.05). The most influenced concept indicator in this study was the concept of molecular geometry types with an increase of 57% in students’ correct answers.       Keywords: student’s understanding, molecular geometry, intertextual based learning, 3d visualization, undergraduate students. DOI: http://dx.doi.org/10.23960/jpmipa/v25i3.pp1468-1479

Abstract

This article examines organic chemistry educational games developed between 2017-2023. The purpose of this study is to find out the types of educational games that are most developed, organic chemistry materials that have been developed in the form of educational games, and the positive impact of educational games in studying organic chemistry. The method used in this study is a systematic literature review. The systematic literature review is carried out in three stages, namely the planning stage, the implementation stage, and the reporting stage. Based on the results of the study, 38 articles were obtained by the criteria and further analysis was carried out. The results of the analysis show that organic chemistry educational games are developed with various types of games both in digital and non-digital forms. The most developed organic chemistry educational games are strategy video games and card games. The most developed material in the form of educational games is the molecular structure of organic compounds which is shown to deepen students' understanding in organic chemistry courses.

Abstract

This research aims to produce an intertextual-based learning video on the concept of the effect of concentration on shifting equilibrium. This research uses the development research method (R&D) with the ADDIE development model (Analysis, Design, Development, Implementation, and Evaluation). The resulting product is an animated video in the form of mp4 which contains the concept of the effect of concentration on shifting equilibrium. Based on the assessment of product quality by content experts obtained a percentage of 85.71% with a very good category (VG); from the pedagogy expert assessment obtained a percentage of 90.27% with a very good category (VG); from the media expert assessment obtained a percentage of 95.60% with a very good category (VG). The video was implemented by limited testing to high school students in class XI as many as 34 students, and chemistry teachers using questionnaires, and according to the assessment of high school chemistry teachers obtained a percentage of 97.40% in the very good category (VG). This product received a positive response from students with a percentage of 90%. Based on the feedback received from experts, teachers and student responses, this learning video was revised so that it can be used as an alternative media for the chemistry learning process in the classroom.
