The Effect of E-Worksheets With The Problem Based Learning Model Assisted by PhET on Global Warming Material on Critical Thinking Skills

I Made Aditya — 2025-04-23

The purpose of this study is to investigate the effect of students' critical thinking skills in relation to the issue of global warming when using Problem-Based Learning (PBL) e-worksheets assisted by PhET. Students from classes X2 and X4 participated in this study, which was conducted at SMA Negeri 1 Seputih Raman during the odd semester of the 2023/2024 academic year. In this non-equivalent control group research design, the dependent variable is critical thinking skills, the moderator variable is the PBL model, and the independent variable is the PBL-based e-worksheet assisted by PhET. The study results indicate that the use of PBL-based e-worksheets assisted by PhET enhances students' critical thinking skills. This is confirmed by the n-gain test results, which show that the control class obtained a low score of 0.299, while the experimental class achieved a moderate score of 0.498. Additionally, the effect size test produced a score of 1.78, which falls into the very high category. In conclusion, compared to traditional video-based worksheets, PBL-based e-worksheets assisted by PhET have been proven to be significantly more effective in improving students' critical thinking skills.

The Effect of Project-Based Learning Model (PjBL) with STEM Approach to Promote Students' Critical and Creative Thinking Skills: A Meta Analysis

Azifa Feziyasti — 2025-04-24

Critical and creative thinking skills are essential 21^stcentury competencies needed to prepare students for global challenges and an evolving workforce. Despite their importance, the 2018 PISA results indicate that Indonesian students still exhibit low critical thinking skills, underscoring the need for more effective learning approaches. This take a look at goals to investigate the effect of the STEM-based Project-Based Learning (PjBL) model on critical and creative thinking skills through a meta-analytic approach. The analysis included 20 articles published between 2018 and 2024, covering two variables: subject domains and learning materials. The findings discovered that STEM-based PjBL had a big impact, with excessive average impact sizes for essential questioning abilities, in particular in dynamic fluid topics, and for creative wondering talents in biodiversity subjects. PjBL combined with the STEM method effectively enhances students' analytical, communication, and collaboration skills through active engagement in real-world problem-solving. Therefore, the STEM-based PjBL model is a relevant approach to fostering critical and creative thinking skills in 21st-century education.

Qualitative Analysis of Physics Learning Problems in High School Based on Students' Intrinsic and Extrinsic Factors

Dewi Wulandari — 2025-04-28

This study aims to analyze the problems in Physics learning at SMAN 1 Punggur. This study is a qualitative research with a grounded theory design focusing on intrinsic and extrinsic factors that influence student understanding. The informants of the study were students and physics teachers at SMAN 1 Punggur. Intrinsic factors include motivation and interest in learning, students' initial abilities, conceptual difficulties, students' practical skills, understanding of abstract concepts, problem-solving skills, collaboration and communication skills. While extrinsic factors include teacher learning strategies, limited facilities and infrastructure, and use of technology in learning. Data collection techniques used in this study were student questionnaires and in-depth interviews with students and teachers. The results of the analysis showed that the problems of physics learning at SMAN 1 Punggur lie in intrinsic factors, namely low motivation and interest in learning, conceptual difficulties, and problem-solving skills.

This study aims to determine the effectiveness of interactive multimedia-assisted learning media in improving concept understanding and students’ learning interests and determine students’ responses to interactive multimedia learning media. The research method using Pre-test Post-test Control Group Design. The data collection techniques used were observation, tests, and questionnaires. The subjects of this study were students of class X SMA Negeri 1 Petanahan with a limited trial of 10 students, an experimental class of 36 students, and a control of 36 students. The data obtained were analyzed using the n-gain formula with n-gain criteria. The result of this study indicate the effectiveness of interactive multimedia learning media on concept understanding and learning interest seen from the results of pretest posttest concept understanding and pre post learning interest. The result of data analysis showed that the understanding of concept and interest in learning in the experimental class both overall and in each indicator experienced a better increase than in the control class. The result of the n-gain value of increasing concept understanding is 0.69 with a moderate category and the result of the n-gain value of increasing interest in learning is 0.69 with a moderate category. Thus it can be concluded that the interactive multimedia learning media developed can effectively improve learning interest.

Comparison of Students Science Process Skills on Measurement Material Based on Gender

Bayu Bayu — 2025-04-30

This study is a survey study conducted because of the different tendencies between male and female students. In addition, there has been no study that specifically examines each SPS indicator of male and female students with the aim of showing weaknesses and strengths between them based on the SPS indicators. Based on this statement, this study aims to describe and compare the profiles of basic science process skills of male and female students. This study uses tests as instruments and quota sampling techniques to select grade X students from State Senior High Schools in Singkawang. Data were analyzed using a combination of quantitative descriptive analysis and comparative statistical tests. The results of the study showed that overall, most of the basic science process skill indicators were in the 'moderate' category for both genders. However, the communication indicator stood out in the 'high' category. Female students had an advantage in basic science process skills compared to male students, although both genders showed the same weaknesses. On the other hand, male students were only superior to female students in the measurement indicator.
