Abstract

This study aims to analyze the relationship between the quality of Free Body Diagram created by students and their understanding of Newton's Laws. This research employs a quantitative correlational method using a written test instrument and includes 40 eighth-grade students MTsS Lama Inong, Southwest Aceh Regency, using the purposive sampling technique. Data analysis was conducted using descriptive statistics, normality tests, linearity tests, Pearson correlation analysis, and significance tests. The results show that the average quality score of students' Free Body Diagram is 70.62, while the average conceptual understanding of physics is 60.87. The Pearson correlation test yielded a value of 0.900, with a t-value of 12.694, which is greater than the critical t-value of 2.024. The determination value of 0.804 indicates that the quality of Free Body Diagram contributes 80.4% to students' conceptual understanding. These findings demonstrate a very strong and significant relationship between the quality of Free Body Diagram created by students and their understanding of Newton's Laws. Therefore, the use of Free Body Diagram can serve as an effective instructional tool for enhancing students' conceptual. The implications of this study emphasize the importance of integrating visualization strategies in physics education to improve students' conceptual comprehension.

Abstract

This study aimed to determine the effectiveness of using concrete teaching aids on students' learning outcomes in Mathematics, particularly on multiplication material, for Grade III students at SD Negeri 95 Palembang, specifically Class III.A. The research employed a quantitative approach with a quasi-experimental method using a Nonequivalent Control Group Design. The study applied a saturated sampling technique, involving 18 students from Class III.A as the research sample. Data analysis techniques included the normality test, homogeneity test, and hypothesis testing using the paired sample t-test.The results of the hypothesis test showed that the Sig. (2-tailed) value was 0.001 < 0.05 and the calculated t-value was greater than the t-table value, indicating that H₀ was rejected and Hₐ was accepted. Therefore, it can be concluded that the use of concrete teaching aids is effective in improving students' learning outcomes in mathematics learning for Grade III students at SD Negeri 95 Palembang. The improvement in students' learning outcomes was also reflected in the increase of the average pretest score from 47.78 to 81.11 in the posttest, with an N-Gain score of 0.64 (64%), which falls into the moderate or fairly effective category
