Abstract

Buffer solutions are a crucial concept in chemistry that students often find difficult to grasp. An effective method to enhance students' understanding is through the use of dual representations assisted by animation. Dual representations involve using various forms of visualization, such as diagrams, graphs, and animations, to help students comprehend abstract concepts more effectively. The research type employed is research and development (RD) using a 4-D model consisting of four stages: define, design, develop, and disseminate. The research subjects were 26 students from class XII MIPA 1 SMA Negeri 5 Banda Aceh. Data collection techniques were conducted by distributing questionnaires for student needs analysis, module and animation feasibility assessment, educator response to modules and animations, and student understanding tests. The developed module obtained very good assessment results from 2 validators with an average percentage of 89.16%, while the animation media received very good assessment results with an average percentage of 80.43%. Educators' responses to modules and animations were categorized as very good, with percentages of 94.17 and 95.84% respectively. Students' responses were also categorized as very good with an average percentage of 87.2%. The results of students' understanding were categorized as good with an overall score of 82.60%. Based on the results of this research, it is concluded that the animation-assisted multiple representation module on buffer solution material is highly suitable for use as teaching material in the learning process

Abstract

This study is grounded in the fact that students learning outcomes in green chemistry are relatively low, which are attributed to conventional teaching methods that involve students only minimally. This study aims to investigate the effect of project-based learning implementation on enhancing students learning outcomes in the topic of green chemistry. A quasi-experimental design with a pretestposttest control group was employed. The participants were tenth-grade students at MAS Darul Ihsan, assigned to an experimental class using PjBL and a control class applying traditional instruction. Data were collected through cognitive achievement tests and student activity observation sheets. The data were analyzed using an independent t-test, yielding a significance level of 0.000. Findings revealed a significant difference in learning outcomes between the two groups, with the experimental class achieving an N-Gain score of 0.73 (high category), while the control class obtained 0.37 (medium category). These results demonstrate that the implementation of PjBL effectively enhances student engagement and conceptual mastery and awareness of the importance of green chemistry principles. Therefore, PjBL can be recommended as an effective instructional model to optimize learning outcomes and foster environmentally conscious attitudes among students

Abstract

One aspect of process science skills that learners need to have is the ability to interpret. The ability to interpret graphs in students is currently considered difficult and still belongs to the very low category. This study aims to analyze the relationship between mathematical understanding and the learning styles of students in terms of their ability to interpret graphs. This type of research is descriptive-quantitative. The research sample consisted of class XI students at SMA Negeri 4 Takengon, which amounted to 67 students. The research data was collected using learning style-type questionnaires, multiple-choice questions on linear program material, and reaction rate material. The ability to interpret the graphs of students at SMA Negeri 4 Takengon is on the "medium" criterion, while the students' mathematical understanding is on the "very high" criterion. Students with visual learning style types are more dominant and have an average score of mathematical understanding and the ability to interpret graphs higher than students with auditorial and kinesthetic learning styles. The result of the correlation coefficient r = 0.912 shows a significant positive relationship between mathematical understanding and the ability to interpret graphs with a "high" and unidirectional interpretation
