Abstract

This study aims to evaluate the impact of project-based learning (PjBL) in mathematics on the development of 21st-century skills, including critical thinking, communication, collaboration, and creativity. These skills are essential for preparing students to face the challenges of the modern era. However, traditional teaching methods often prove inadequate for optimizing these skills. Utilizing a 3×4 quasi-experimental factorial design, this study involved 90 students, proportionally selected from a population of 872 through random sampling. Data were collected using a learning style questionnaire, observations of teacher instructional methods, and a written test to measure 21st-century skills. Data were analyzed using tests for normality and two-way ANOVA. The results demonstrated that the PjBL approach significantly enhanced students' 21st-century skills (4Cs: Critical Thinking, Collaboration, Communication, Creativity), particularly for those with a kinesthetic learning style and when employing technology-based teaching methods. The interaction between PjBL, students' learning styles, and teachers' instructional methods was found to be effective in fostering the development of these skills, especially in the areas of creativity and problem-solving. This research underscores the importance of innovative approaches in mathematics education to support the development of 21st-century skills.

Abstract

This research addresses the low critical mathematical thinking abilities of students when facing mathematical problem-solving challenges. The study aims to evaluate the impact of implementing various teaching approaches, including Contextual Teaching and Learning (CTL), Problem-Based Learning (PBL), and Direct Instruction (DI) models, on students' critical mathematical thinking abilities. Participants included 276 eighth-grade students from SMP La Tansa Mashiro 1, 2, and 3 in Lebak Banten during the academic year 2022/2023, divided into three classes. Samples were selected using simple random sampling, resulting in 94 students for CTL, 92 students for PBL, and 90 students for DI instructional models. Data collection involved self-efficacy questionnaires and critical mathematical thinking ability tests, analyzed using a two-way ANOVA. The findings suggest that implementing CTL and PBL models positively influences students' critical mathematical thinking abilities. Additionally, students' self-efficacy levels contribute significantly to their critical mathematical thinking abilities. Furthermore, a significant interaction was observed between the implementation of CTL, PBL, and DI models and students' efficacy levels, collectively influencing students' critical mathematical thinking abilities. These results emphasize the importance of employing active approaches, such as contextual, problem-based, and direct instructional methods, while also enhancing students' self-confidence to improve their critical mathematical thinking abilities. It is hoped that implementing these recommendations will enhance the effectiveness of mathematics learning and foster the development of students' critical thinking skills.
