Abstract

The quality of measurement instruments is an essential factor in ensuring accurate and meaningful learning assessments. However, many test instruments have not undergone empirical validation, which reduces their reliability and accuracy. This study aimed to develop and empirically validate a conceptual understanding test on dynamic electricity for high school students. A quantitative descriptive design was employed involving 66 students who had studied the topic of dynamic electricity. Item analysis included validity, reliability, discrimination index, and difficulty level tests. The results showed that 11 multiple-choice items met the criteria for validity and reliability with appropriate levels of difficulty and discrimination. These findings indicate that the developed instrument has good quality and can consistently measure students’ conceptual understanding. Therefore, this test instrument can be used by teachers and researchers as a representative and high-quality tool to evaluate students’ conceptual mastery and improve the quality of physics learning assessment.

Abstract

This study analyzed global publication trends, research instruments, student difficulties, strategies, and pedagogical recommendations related to kinematics graph topics based on articles published in scientific journals between 2015 and 2025. A systematic literature review was conducted following the PRISMA protocol, with 50 articles indexed in Scopus and Web of Science examined. Results indicated fluctuating publication trends, peaking in 2019. Germany contributed the most publications, followed by Turkey and Mexico, with quantitative methods predominating. Most studies employed test instruments, particularly the Test of Understanding Graphs in Kinematics (TUG-K), with university and high school students as the largest sample groups. Thematic analysis revealed that students’ main difficulties involved misconceptions in representation, translation, and interpretation of graphs. Effective strategies included diagnostic instruments, technology integration (eye-tracking, virtual laboratories, real-time sensors, artificial intelligence), and contextual pedagogical approaches that enhanced graph comprehension and data literacy. Recommendations emphasized the need for expanded sampling and instrument validation in future research. Learning strategies should emphasize repeated practice, contextual exploration, and technology use. Teachers were advised to strengthen professional competence and design technology-based learning, while policymakers were urged to adapt curricula and allocate more time to foster deeper understanding of kinematics graphs
