Abstract

One of the main issues in physics education is the high incidence of student misconceptions, particularly regarding the concept of dynamic fluids. Misconceptions can hinder conceptual understanding and negatively affect students’ cognitive abilities in comprehending more advanced material. This study aims to identify the level of misconceptions and determine the sources of information that contribute to the formation of these misconceptions. The research employed a descriptive quantitative approach using the Five-Tier Diagnostic Test instrument, which consists of five components: answer selection, confidence in the answer, reasoning, confidence in the reasoning, and source of information. The research subjects were all 19 eleventh-grade students of SMA Swasta Methodist 7 Medan in the 2024/2025 academic year. The results showed that 12% of the students experienced misconceptions, with the most dominant subtopic being the continuity equation (14%). The primary sources of misconceptions were identified as personal reasoning (25%) and peer interaction (20%). These findings indicate that both internal and social factors significantly influence the development of incorrect conceptual understanding. Therefore, the use of a five-tier diagnostic instrument is recommended as an early identification tool to design more effective and targeted learning improvement strategies.

Abstract

Conceptual skills in physics are an essential foundation for students to understand natural phenomena deeply and analytically, yet conventional teaching often fails to connect abstract theory with real-life contexts. This study aims to develop a physics learning module integrated with the local wisdom of the Toba Batak Taganing on mechanical wave material to enhance students' conceptual skills. The developed module links concepts of waves, resonance, and interference with the acoustic principles of the Taganing musical instrument through a Problem-Based Learning approach. Expert validation results demonstrated a high level of feasibility, with details of 78% (Feasible category) by subject matter experts, 85% (Highly Feasible) by cultural experts, and 97% (Highly Feasible) by language experts. A limited trial with grade XI students showed an improvement in conceptual skills, specifically an abstraction ability of 71% (Good) and systematic thinking of 72% (Good). Teacher and student responses to the module were very positive, with a practicality level of 81%, indicating that the module is not only easy to use but also contextual and engaging. These findings confirm that integrating local wisdom into ethnoscience-based physics learning design is not only effective in strengthening students' conceptual understanding but also plays a strategic role in preserving cultural heritage and fostering learning engagement.

Abstract

The purpose of this study was to determine the effect of the PhET Simulation-Based Problem-Based Learning model on Students' Science Process Skills (KPS) at SMAS Bani Adam A's. The study took place in June 2025 and the quasi-experimental method was a nonequivalent control group design. In this study, the sample was determined through purposive sampling where class X-3 was the experimental class and X-1 the control class with the same number of students, namely 30 students. The research instrument was a multiple-choice KPS test totaling 20 questions. Before being given treatment, a pretest was given and then a prerequisite test was carried out to ensure the data was normally distributed and homogeneous. Given in both classes, the average score was 47.6 in the experimental class and 48 in the control class, each having a standard deviation of 15.35 and 15.5, respectively. Then given treatment, the posttest results showed an average score of 78.16 in the experimental class and 63.66 in the control class with standard deviations of 10.94 and 13.38, respectively. The data analysis used a one-tailed t-test at a significance level of α = 0.05, indicating that t count > t table. The results demonstrated a significant difference in both classes, thus supporting the application of the PhET Simulation-Based Problem-Based Learning model to the KPS.

Abstract

In the era of technology-based learning, innovation is required to connect physics concepts with real-world phenomena to enhance students’ deep and meaningful understanding. This study aims to examine the effectiveness of a contextual learning strategy based on geoelectric principles using the Electrical Conductivity Soil Geoelectric (ECSG) sensor to improve high school students’ understanding of resistivity and electrical conductivity concepts. The research employed a quasi-experimental method with a one-group pretest–posttest design involving 34 students of class XI Science at SMA Negeri 1 Pagaran, North Tapanuli Regency. The research instruments consisted of a conceptual understanding test, procedural skills observation, and a student response questionnaire. The results showed an increase in the average score from 46.50 to 75.80 with an N-Gain value of 0.55, categorized as moderate. Procedural skills achieved an average score of 3.33 (good category), while student responses to the learning implementation reached an agreement level above 85% (very good category). These findings indicate that the application of geoelectric sensor technology in physics learning can enhance measurement accuracy, active participation, and students’ learning motivation. Thus, the ECSG-based geoelectric contextual approach is effective in strengthening conceptual understanding, scientific skills, and the relevance of physics learning to real-life contexts in agrarian environments.
