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.

Abstract

: Optics is a branch of physics related to complex and abstract daily life technology. Critical thinking skills can make a very meaningful contribution to students in understanding abstract material such as optics. Therefore, this study aims to describe students' critical thinking skills in the context of optics learning. Descriptive method with qualitative approach was applied to 108 students of class XII MIPA. The research instrument consisted of 5 description questions. The results showed that the average critical thinking ability of students was 55.28 (medium category). When viewed from each sub-matter, the percentage of students who fall into the low critical thinking ability category is 53.7% (light reflection material) and 54.6% (light refraction material). In a more in-depth analysis, the percentage of students' critical thinking skills on each indicator also tended to be higher in the low critical thinking ability group, with values of 66.7% (interpretation indicator), 71.3% (analysis indicator), 65.7% (inference indicator), 86.1% (evaluation indicator), and 80.6% (explanation indicator). The implications of the results of this study indicate the need to apply learning methods that can train students in solving problems in everyday life that are general and complex, such as PjBL and the STEAM approach.
