Abstract

Problem-solving ability is crucial for students to face 21st-century challenges, especially in physics education, where many concepts are abstract. Despite its importance, students' problem-solving skills in elasticity are often low due to teacher-centered approaches and insufficient use of problem-solving models. This study aims to evaluate the impact of the IDEAL Problem-Solving model on students' problem-solving abilities concerning elasticity material. The research method and design were quasi-experiments with a nonequivalent posttest-only control group design. Analysis revealed outstanding implementation of the IDEAL model, with normality and homogeneity tests supporting the sample's suitability. The t-test (α = 0.05) confirmed that the IDEAL model significantly enhanced problem-solving skills in elasticity. The findings suggest that adopting student-centered models like IDEAL can improve learning outcomes and problem-solving abilities and provide a basis for further research on similar models in other educational contexts.

Abstract

This research was motivated by the importance of problem-solving skills as part of the higher-order thinking skills required in physics learning, especially in complex and abstract thermodynamics materials. The complexity of materials, including internal energy, ideal gases, and the laws of thermodynamics, often caused difficulties for students in understanding and solving problems. This study aimed to analyze students’ problem-solving skills in thermodynamics based on Polya’s problem-solving stages. The research employed a survey method involving 36 students who completed a problem-solving test covering topics of internal energy, ideal gas, and the laws of thermodynamics. The overall problem-solving score was 53,59%, categorized as low. The highest achievement was in understanding the problem (64,8%, moderate), followed by devising a plan (54,01%, low), carrying out the plan (46,60%, low), and looking back (45,37%, low). These results indicated that students experienced difficulties in selecting appropriate concepts, applying relevant formulas, and evaluating solutions systematically. The findings suggested that students’ problem-solving skills in thermodynamics remained weak and required more effective instructional approaches. This study contributed to the achievement of Sustainable Development Goal 4 (Quality Education) by highlighting the need to enhance problem-solving skills to improve the quality of physics education.

Abstract

Instruments for measuring problem-solving skills in physics education have primarily been developed in the context of classical physics. In contrast, the astronomy context, based on real phenomena, has remained relatively limited. One phenomenon closely related but not widely utilized as an assessment context was night sky brightness as an indicator of light pollution. Therefore, this study aimed to examine the feasibility of problem-solving skill instruments in the context of night sky brightness as an indicator of light pollution, as well as to describe physics education problem-solving skills. This study employed a quantitative descriptive design involving 75 students in physics education. The instrument was designed in the form of a contextual problem, covering four problem-solving stages and was analyzed using the Rasch Model. The analysis results indicated that the instrument met the feasibility criteria for use as a measurement tool for problem-solving skills. The use of this instrument provided an overview of students’ abilities at each problem-solving stage, so that the assessment did not focus solely on the final score but also on students’ thinking processes. Thus, this study contributed to the development of an astronomy-based assessment instrument that could be used as a diagnostic tool for problem-solving skills in physics learning.
