Abstract

This study investigates the correlation between representation competence and conceptual understanding of linear motion kinematics, by representation type and gender, among undergraduate students. A quantitative survey design was conducted with 228 students (136 male and 92 female) who had completed a basic physics course. Data were collected using seven validated essay items adapted from the Test of Understanding Graphics in Kinematics (TUG-K2) to measure students' representational competence and conceptual understanding across graphical, diagrammatic, and verbal representations. Descriptive statistics, Kruskal-Wallis test, Wilcoxon test, and Pearson correlation analysis were used. Results showed that students' representation competence was generally moderate (mean=1.130) and differed significantly across representation types, while their conceptual understanding was relatively low (mean=0.419) and varied significantly across kinematics concepts. Although female students showed slightly higher average representation competence scores, no statistically significant gender differences were found in either representation competence or conceptual understanding. A strong positive correlation was identified between representation competence and conceptual understanding, indicating a close association between the two constructs. However, the correlational design does not allow causal conclusions to be drawn. These findings highlight the importance of explicitly integrating various representations into physics teaching to support deeper conceptual understanding in linear motion kinematics

Abstract

Objective: This study aims to examine the effectiveness of the Modeling-based Learning (MbL) model in improving students’ science process skills (SPS) on the topic of Black’s Principle. SPS is essential for mastering STEM, yet remains relatively low among Indonesian students, as indicated by PISA and TIMSS results. Method: The research employed a quasi-experimental design using a pretest-posttest control group design. Two high school classes, each consisting of 30 students, participated in the study. The instruments used included an SPS test and questionnaires that measured skills such as observing, formulating hypotheses, conducting experiments, and interpreting and communicating data. Data analysis involved N-Gain calculations, normality tests, and paired t-tests to confirm statistical significance. Results: The findings revealed that the experimental class taught using the MbL model showed a significant improvement in SPS, with an average N-Gain score of 0.8 (high category). In contrast, the control class, which did not receive MbL-based instruction, only reached an average N-Gain score of 0.5 (medium category). Statistical tests confirmed the significance of these differences, demonstrating the positive impact of the MbL model on SPS development. Novelty: This study highlights the potential of the MbL approach as an innovative and effective teaching model to enhance science process skills at the secondary school level. By integrating modeling activities into learning, the MbL strategy provides students with deeper engagement and better mastery of scientific inquiry processes compared to traditional methods.
