Abstract

This study investigates the impact of a PhET-assisted problem-solving model on high school students' physics problem-solving skills, especially in resource-limited educational settings in Indonesia. Conducted as a quasi-experimental study with a non-equivalent control group pretest-posttest design, the research involved 50 students from SMAN 10 Kendari, divided into an experimental group receiving instruction through the PhET-assisted model and a control group following traditional teaching methods. The intervention consisted of structured learning sessions incorporating PhET simulations, designed to engage students actively with physics concepts through virtual experiments. Data were collected using a 10-item problem-solving test and analyzed using a one-way ANOVA to determine the statistical significance of differences in performance between groups. Results revealed a significant improvement in the experimental group, with a mean increase of 47.91 points from pretest to posttest (M = 83.54, SD = 15.22) compared to the control group’s improvement of 39.11 points (M = 74.48, SD = 12.78). The ANOVA results (F = 23.526, p < 0.001) confirm that the PhET-assisted model significantly enhanced students' problem-solving skills. These findings suggest that PhET simulations can be an effective tool for improving physics learning outcomes in schools with limited access to laboratory resources. Integrating PhET simulations into the physics curriculum could provide students with accessible, interactive learning experiences that bridge the gap in traditional laboratory access, fostering a deeper understanding and application of physics concepts.

Abstract

Geography learning about spatial patterns of villages and cities in high schools still faces obstacles in students' understanding of concepts due to teacher-centered learning. This study aims to determine the effect of problem-based learning (PBL) models with the help of Canva media on students' conceptual understanding. Quasi-experimental research was conducted at SMAN 10 Kendari on class XII IPS students. Class XII IPS.1 was designated as an experimental class that learned using problem-based models combined with Canva media, and class XII IPS.2 became a control class with conventional learning methods based on the same abilities. Research data were collected through a concept understanding test and then analyzed using parametric inferential statistical tests. The analysis using independent sample t test after get the normality and homogenity test. The results of the t-test showed a significance value of 0.000, with students in the experimental class having a higher increase in conceptual understanding than those in the control class. This finding shows that PBL utilizing Canva media has proven to be effective in helping students understand the subject matter in problem-oriented learning steps and media that attract students' attention. This study implies that the use of Canva digital media in PBL can be an effective strategy to improve students' conceptual understanding. Teachers are advised to use Canva digital learning media as a teaching aid, especially when implementing PBL, so that students can more easily understand the concepts being studied.
