Abstract

Critical thinking is one of the essential skills required of students in the 21st century. This research aims to provide an overview of students' critical thinking skills at in high school while studying the concept of Newton's Laws. Critical thinking skills refer to the cognitive processes employed by students to analyze and evaluate information effectively, enabling sound decision-making. The research method used is a descriptive-quantitative approach, involving a population of 130 students and a purposive sample of 60 students. Data were collected using a critical thinking test comprising 31 multiple-choice questions, addressing four indicators: interpretation, analysis, evaluation, and inference. The result of the study show that students' performance on the interpretation indicator predominantly fell into the low category, with 53.33%. Critical thinking skills for the analytical indicator were similarly low, at 38.33%. Critical thinking skills for evaluation were also categorized as low, at 43.33%. Meanwhile, critical thinking skills for inference were slightly better, being in the medium category at 46.67%. In general, students' critical thinking abilities at SMAN 5 Sidrap were primarily low, with 60% of students falling into this category. One of the factors causing students' poor critical thinking skills is the infrequent exposure to exercises designed to measure these skills. Therefore, implementing learning models that actively enhance critical thinking skills is essential.

Abstract

The rapid advancement of education in the era of Industrial Revolution 4.0 demands the mastery of critical thinking as a core competency for students. However, physics learning at the tertiary level still tends to be teacher-centered, resulting in low levels of critical thinking skills. This study aimed to develop Project-Based Learning (PjBL) teaching materials to enhance students’ critical thinking abilities in physics, specifically in kinematics. The research employed the Research and Development (R&D) method using the 4D model (Define, Design, Develop, and Disseminate). Participants were physics education students at Makassar State University in the 2024/2025 academic year. Data were collected through expert validation sheets, student response questionnaires, project performance assessments, and critical thinking skill tests, and then analyzed using descriptive, quantitative, and qualitative approaches. The results showed that expert validation of the developed teaching materials reached an average of 96.96% (very valid), while student responses obtained 91.71% (very positive). Students’ project creation ability achieved an average score of 84.25 (in the good category). Critical thinking skills improved significantly, with pretest and posttest averages of 56.7 and 84.3, respectively, and an N-Gain score of 0.63 (moderate improvement). The novelty of this research lies in integrating PjBL into structured teaching materials that directly target critical thinking indicators, which were not thoroughly addressed in prior studies. In conclusion, the developed PjBL-based teaching materials are valid, practical, and effective in fostering critical thinking, and they provide an innovative contribution to physics education by offering a model that prepares students to meet 21st-century academic and professional challenges.

Abstract

This research aims to describe the influence of mathematical logical intelligence and visual spatial intelligence on the ability to interpret kinematic graphs for class XI MIPA SMA Negeri 5 Makassar, both individually and in groups. This research is ex-post facto research. The research population was all students in class XI MIPA SMA Negeri 5 Makassar totaling 288. The sampling method used was simple random sampling. The technique used to determine the sample size was the Solvin technique at the α = 0.05 level and the sample obtained was 190 people. Measurement of mathematical logical intelligence and visual spatial intelligence with the ability to interpret kinematic graphs using test instruments in the form of multiple-choice questions each with 15 questions and the Test of Understanding Graph – Kinematics version 4.0 with 20 questions. The research data was processed using descriptive statistics, linear regression and product moment correlation. The results of the research reveal that (1) there is a significant influence between logical-mathematical intelligence and the ability to interpret kinematic graphs of class XI MIPA students at SMA Negeri 5 Makassar, (2) there is a significant influence between visual-spatial intelligence and the ability to interpret kinematic graphs of class SMA Negeri 5 Makassar and (3) there is a significant influence of logical-mathematical intelligence and visual-spatial intelligence together on the ability to interpret kinematic graphs of students in class XI MIPA SMA Negeri 5 Makassar.
