Abstract

This study aims to analyze the effect of learning based on concreteness fading and multi-representation on prospective teacher students' understanding of geometric optics concepts. The research sample consisted of 40 prospective physics teacher students, selected using the total sampling technique, with 20 students in each experimental and control group. The experimental group received learning with concreteness fading and multi-representation approaches, while the control group received conventional learning. The research instrument was a concept understanding test in the form of descriptions, which was tested for content validity and reliability using the inter-rater reliability method, yielding a Cohen's Kappa coefficient of 0.68. Data analysis techniques included independent samples t-test, ANCOVA, and N-gain. The results of the independent samples t-test showed that, in the posttest, there was a significant difference (p = 0.008 < 0.05) with the average score of the experimental group (M = 21.55) being higher than that of the control group (M = 19.10). ANCOVA test results showed that learning with concreteness fading-multi representation significantly affected students' concept understanding after controlling for the pretest score (p = 0.009 < 0.05). Additionally, the N-Gain test results indicated increased concept understanding in the experimental class (0.75, high category) and the control class (0.56, medium category). Initially, many students struggled and relied solely on one form of representation to explain geometric optics problems. However, after learning, they began to utilize various interrelated representations, including diagrams, texts, and mathematical equations. The findings in this study confirm that learning with concreteness fading and multi-representation approaches is effective in improving understanding of geometric optics concepts.      Keywords: conceptual understanding, concreteness fading, geometric optics, multi-representation, physics learning.

Abstract

Purpose-Scientific reasoning is an essential ability in learning science, including physics. This study aims to assess the scientific reasoning abilities of high school students in Palangka Raya City, focusing on six indicators: conservation reasoning, proportional reasoning, variable control, probabilistic reasoning, correlation reasoning, and hypothetical-deductive reasoning.Methodology-To achieve the goals, descriptive research consisted of 187 samples from six schools in two districts using the multistage stratified random sampling method. The instrument used in this study is Lawson's Classroom Test of Scientific Reasoning (LCTSR), containing twelve multiple-choice items. The data were analyzed using the Kruskal-Wallis test to determine the differences in average scores between schools, and descriptive statistics were used to describe students' general scientific reasoning skills. The analysis results show a p-value of 0.001, indicating that the test detected a statistically significant difference in the average score of scientific reasoning ability among high school students in the sample schools in Palangka Raya City.Findings-The descriptive analysis results showed that the conservation reasoning indicator had the highest percentage of correctness, while hypothetical-deductive reasoning was the least mastered by students. Additionally, most students are in the concrete operational thinking phase, despite having theoretically reached the formal operational phase in terms of cognitive development.Contribution-This finding has implications for educators in designing physics learning strategies that encourage the development of students' scientific reasoning as they progress toward the formal operational phase.
