Abstract

Optical instruments play a crucial role in physics education, providing essential material for students to understand complex concepts. This study aims to evaluate the scientific argumentation abilities of high school students regarding optical instruments. Conducted as a quantitative descriptive study, the research involved 60 eleventh-grade MIPA students from SMA Laboratorium UM. The research instrument was a scientific argumentation test comprising 12 essay questions, designed according to the Toulmin Argumentation Pattern (TAP) adaptation indicators, with a reliability coefficient of 0.332. Student responses were classified into five levels of scientific argumentation based on the TAP model, as developed by Sampson, Enderle, and Walker, which includes elements such as claims, data, warrants, backings, and rebuttals. The findings indicate that 33% of students demonstrated scientific argumentation at level 1, 36% at level 2, and 31% at level 3, reflecting varied levels of proficiency in constructing scientific arguments.

Abstract

Work and energy are fundamental topics in physics. However, enhancing students’ critical thinking skills in these areas remains a challenge. This research aimed to develop and assess the validity and readability of e-modules designed with PjBL-STEAM and virtual simulation media to address this issue. The development process followed a 4D model, and the resulting e-modules were evaluated as strongly valid category. The validation tests yielded percentage scores of 91.6% for media, 89.3% for content, and 88.0% for lesson plans. Additionally, the readability test achieved a score of 84.6%, indicating a excellent level of comprehensibility. These findings suggest that the e-modules based on PjBL-STEAM with integrated virtual simulation media are well-suited for use in physics education, particularly for improving students’ critical thinking skills.DOI: 10.17977/jps.v12i32024p093

Abstract

Optical material is widely applied in everyday technology but remains difficult for students to grasp due to its abstract nature. This challenge is linked to students’ low critical thinking skills—an essential 21st-century competence. This study aims to enhance students' critical thinking on optical topics through the integration of project-based learning with a STEAM approach and visual simulation media (PjBL-STEAM-MSV). A mixed-method design with an untreated control group and pretest-posttest was employed. The participants were 54 students from SMAN 1 Woha, NTB, Indonesia, divided into an experimental group (PjBL-STEAM-MSV) and a control group (conventional instruction). Data collection used a critical thinking essay test (5 items, reliability = 0.636) and interview guidelines. Quantitative data were analyzed using t-tests, N-gain, and effect size; qualitative data through reduction, coding, and interpretation. Results indicated that PjBL-STEAM-MSV significantly improved students’ critical thinking in optics (α = 0.01). The experimental group's N-gain score was 0.48 (moderate), higher than the control group’s 0.20 (low). The most notable improvements in the experimental group were in evaluation and explanation, while in the control group, gains were limited to analysis and explanation. Experimental group students struggled with explanation during presentations due to time constraints, whereas the control group showed difficulty across most indicators due to a focus on rote learning. Interviews revealed that experimental group students experienced more active, interactive, and structured learning. This aligns with the high effect size of 1.7. Further research should explore media development and sustained student mentoring to maximize outcomes.
