Abstract

This study aims to develop learning media by utilizing the TikTok application with the PBLA model on the topic of measurement and to determine the enhancement of participants' argumentation skills. This study is a Research and Development (R&D) study employing the ADDIE development procedure (Analyze, Design, Development, Implementation, and Evaluation). The research subjects were 36 students from class X-E of MAN Purworejo in the academic year 2023/2024. The research instruments used were validation sheets, participant response questionnaires, observation sheets, pretest-posttest questions, and learning implementation sheets. The data analysis results show that the physics instructional video media utilizing the TikTok application with the PBLA model meets the "valid" criteria, with material expert validation scoring 3.45, equivalent to 86.30%, categorized as "good," and media expert validation scoring 3.58, equivalent to 89.58%, categorized as "very good." The developed physics instructional video media using the TikTok application with the PBLA model received a score of 85.5% with the predicate "very good" from participant response testing. Meanwhile, the observation data on learning implementation achieved a Percentage Agreement (PA) score of 99% with the predicate "reliable," meeting the "practical" criteria. Utilizing the TikTok application with the PBLA model is effective according to trial results using a paired sample t-test, which produced a calculated t-value of 0.000 < 0.05, indicating an improvement in argumentation skills after using physics learning media with the TikTok application. Thus, the developed physics learning media is considered "effective" for improving students' argumentation skills based on pretest and posttest scores with a normalized gain of 0.71, which falls into the "high" category.

Abstract

physics plays a significant role in the advencement of science and technology; however, physics learning in schools is often perceived as challenging, and students’ scientific literacy skills are still considered insufficient. This study aimed to evaluate the effectiveness of interactive multimedia-based learning media in improving senior high scholl students’ scientific literacy in physics. The research employed a quantitative approach using a pre-experimental design with a one-group pretest-posttest model. The research subjects consisted of 36 eleventh-grade students (Class XI-1) at a senior high scholl in Kebumen Regency. Data were collected using a scientific literacy test comprising five indicators: observing, measuring, predicting, concluding, and communicating. Data analysis was conducted through quantitative descriptive analysis using percentage scores and N-Gain analysis. The results showed that students’ initial scientific literacy levels varied, with percentages of 73.72%, 72.14%, 62.94%, 63.78%, and 75.08%. After the implementation of interactive multimedia-based learning media, post-test scores increased to 85.89%, 83.39%, 76.22%, 77.92%, and 89.53%. The N-Gain values ranged from 0.36 to 0.58, which fall into the moderate category. These findings indicate that interactive multimedia-based learning media are effective in enhancing students’ scientific literacy skills.
