Abstract

This study aims to improve students' scientific communication skills through the implementation of differentiated VAK (Visual, Auditory, and Kinesthetic) learning in the "Motion and Force" topic for Grade VII of junior high school, in response to the demands of the Independent Curriculum, which emphasizes student-centered learning by accommodating diverse learning needs. This quantitative research employed a quasi-experimental approach with a Nonequivalent Pretest-Posttest Control Group Design. The study involved 100 students from SMPN 1 Tembilahan, divided into experimental and control groups. Data analysis was conducted both descriptively and inferentially to assess the impact of VAK-differentiated learning compared to conventional scientific learning methods on the enhancement of scientific communication skills. Scientific communication abilities were evaluated based on six indicators: information retrieval, scientific reading, scientific writing, listening and observation, information representation, and knowledge presentation. Pretests and posttests were administered to both groups. The results showed that the average posttest scores of the experimental group were significantly higher than those of the control group. Furthermore, the MANOVA test confirmed a significant difference in the improvement of scientific communication skills between the groups, indicating that VAK-differentiated learning effectively supports the development of scientific communication competencies among students.Keywords: scientific communication, VAK differentiation

Abstract

The purpose of this study was to evaluate the impact of using the Teams Games Tournament (TGT) cooperative learning model on the conceptual understanding of seventh grade junior high school students. Experimental research with a quasi-experimental design "Nonequivalent control group design" and the research model "Posttest only control group design" is the methodology that will be used. The data collection tool was in the form of a test on the results of understanding the class VII concept of the Solar System material which consisted of 21 multiple choice questions. Descriptive analysis will be carried out with students' conceptual knowledge, and inferential analysis will be carried out with the normality test, homogeneity test, and hypothesis testing using SPSS version 22. After the analysis is carried out, it is known that the average understanding of the concept of the experimental group is 61.10 which is included in the high category, while the mean -the average control group's understanding of the concept of 53.33 is in the sufficient category. The difference in average understanding of concepts between the experimental group and the control group using the wordwall-assisted TGT cooperative learning model is statistically significant. Conclusion from the research: Compared to conventional learning, using the TGT cooperative learning methodology is effective in increasing students' conceptual understanding of the Solar System material.Keywords: Teams Games Tournament, Concept Understanding, Wordwall, Solar System
