Abstract

This type of research is a quantitative approach with a quasi-experimental design in the form of a nonequivalent Control Group Design. The sampling technique was purposive sampling with a sample size of 50 students, namely 25 students from class XI-MIA1 as the control class and 25 students from class XI-MIA2 as the experimental class. The data collection instrument uses multiple choice questions. Meanwhile, data analysis uses prerequisite tests which include normality and homogeneity tests, hypothesis tests and N-gain tests.The results showed that the average posttest score for the experiment was 82.20 and the average posttest score for the control class was 76.20. Based on the results of hypothesis testing using parametric tests, namely the independent t-test, sig results were obtained. (2-tailed) of 0.026 < 0.05, meaning that H0 is rejected and Ha is accepted or there is an influence of the Problem Based Learning (PBL) model assisted by the Quizizz application on student learning outcomes. Meanwhile, the average N-Gain score for the experimental class is 0.72, which is in the high category. So it can be concluded that there has been an increase in student learning outcomes in the experimental class which implemented the Problem Based Learning (PBL) model assisted by the Quizzizz application.

Abstract

Purpose-The implementation of web-based virtual laboratories in physics education has significant potential to enhance students' scientific process skills and conceptual understanding of physics. The objectives of this study are: (1) to analyze the impact of implementing an interactive web-based virtual laboratory in activitiy physics learning, and (2) to describe students' perceptions of the use of this virtual laboratory.Methodology-The research design follows a pre-experimental method with a one-shot case study approach. The population consisted of all twelfth-grade students, distributed across four classes with consisting of 24 students for the samples. Observations of students’ scientific process skills were conducted to assess the intervention's impact. A questionnaire was administered after the learning session to measure students’ SPS activities before and after the intervention.Findings—The results of the observational data analysis on scientific process skills revealed an average activity percentage of 90.3%, indicating that the interactive web-based virtual laboratory is highly effective in supporting virtual practical-based learning. Additionally, the analysis of students' perceptions showed an average perception score of 86.42%, categorized as "very good."Significance– These findings suggest that virtual laboratories can serve as an innovative solution in physics education. However, improvements in operational aspects are still necessary to overcome existing challenges.Keywords: Virtual laboratory Student activities Perception Physics learning Website
