Abstract

This study aims to examine the effectiveness of Project-Based Learning (PjBL) in the context of the Independent Curriculum to improve mathematics problem-solving skills in junior high school (SMP) students. The Independent Curriculum emphasizes independent and contextual learning, encouraging the application of methods that can develop students' critical and creative thinking skills. The research method uses a mixed-methods approach with a quasi-experimental design and qualitative deepening. A total of 70 junior high school students from two classes were selected purposively; one class as an experimental group that followed PjBL-based mathematics learning, and one control class with conventional learning methods. Quantitative data was collected through math problem-solving tests before and after the intervention, while qualitative data was obtained from classroom interviews and observations to explore student motivation and engagement. Statistical analysis showed a significant improvement in problem-solving ability in the experimental group compared to the control group. In addition, qualitative results revealed that PjBL increases students' learning motivation, active engagement, and collaborative ability in solving complex mathematical problems. This study confirms that the integration of PjBL in the Independent Curriculum is effective in improving mathematical problem-solving skills holistically. The study presents practical implications and recommendations for the development of innovative and contextual mathematics learning in secondary schools.

Abstract

This study aims to determine the effectiveness of STEM-based TPACK learning models on students' 21st century skills in Indonesia. This research is a meta-analysis research by analysing 13 national and international journals published in 2021-2024. The inclusion criteria in this study are that the research comes from SINTA and Scopus indexed journals, the research must be experimental or quasi-experimental methods, research related to the STEM-based TPACK learning model, the dependent variable is related to 21st century thinking skills consisting of critical thinking and problem solving, creative, collaborative and communicative, the research has complete data to calculate the effect size value, and the research must be open access and sample size > 28 students. Data search through google scholar, ERIC, Taylor of francis and Mendeley. The data filtering process with the PRISMA method. Data analysis is quantitative analysis by calculating the effect size value with the help of the SPSS application. The results concluded that the STEM-based TPACK learning model had a positive effect on students' 21st century thinking skills in Indonesia with an average effect size value (ES = 1.09) in the high effect size category. The findings provide information for teachers that the implementation of STEM-based TPACK learning is effective in developing students' 21st century thinking skills
