Abstract

Physics learning plays a very important role in everyday life, therefore, students' understanding of physics material is very important. Students who understand physics concepts well will find it easier to apply these physics concepts in everyday life. However, some students had difficulty understanding physics material, especially when they misunderstood the concept. Physics concepts formed webs that were connected to one another, so that a correct understanding at the previous level was one of the determining factors for success. The purpose of this research was to develop an e-Diagnostic based on the Certainty of Response Index (CRI) with the help of Google Forms to identify students' misconceptions about simple harmonic motion material. The type of research used was Research and Development which was adapted from the Four-D model. Grade 10 students were used as research subjects. The data described were in the form of instrument validity and results of identifying misconception profiles in students. The results of the validity test conducted by 2 experts and 8 colleagues stated that the developed test instrument was feasible to use. The results of the identification of misconceptions that were carried out showed that there were misconceptions, especially in the restoration style sub-topic. In conclusion, the e-Diagnostics that was developed is feasible to use as a tool to identify student misconceptions.

Abstract

Thinking styles and metacognition are related as they both have the same space in assessing one’s own abilities. Metacognition and thinking styles have an important role in unlocking the potential of physics problem solving. The objective of this study is to investigate the relationship between metacognition, thinking styles (particularly those proposed by Gregorc), and physics problem solving. The study involved a cohort of 364 students who were pursuing a physics degree at Tadulako University. The results indicated that metacognition behavior exhibited in the process of solving physics problems was classified as high category. The most dominant thinking style was abstract sequential, while the least was concrete random. The data analysis showed a significant difference in metacognition behavior between groups categorized by thinking style. Specifically, the concrete sequential (SK) group exhibited a significant difference with the abstract random (AA) group. These results provide further understanding of how metacognition and thinking styles play a role in physics problem solving. This study contributes significantly to comprehending the connection between metacognition, thinking styles, and the successful resolution of physics problems. The insights gained provide prospects for formulating more efficient physics learning methods that will ameliorate students' aptitude in tackling physics problems.

Abstract

Assessment of science process skills can be conducted through tests or non-tests. However, observations, as one non-test technique, often face challenges related to space, time, and evaluator resources. A polytomous-type paper-and-pencil test was developed to address these issues. Item characteristic analysis is an essential aspect of instrument development; thus, this study reports the instrument analysis within the development of this assessment, using the item response theory approach. A total of 415 high school students in Sumedang completed 30 items depeloved. They came from four high schools selected based on the 2022 Asessmen Kompetensi Minimum (AKM) criteria. The test of 30 items had previously undergone successful content validity, construct validity, and reliability tests. Based on the item response theory assumptions, all items were eligible for analysis using this approach. Item fit testing revealed that the instrument suited the Generalized Partial Credit Model (GPCM). The analysis was performed using the R Program application. Results showed that all items (100%) were medium difficulty; 21 items (70%) had good discrimination and items (30%) exhibited high discrimination. 14 items were suggested for category reduction due to minimal delta differences or exceedingly low delta values. These findings emphasize item analysis to achieve high-quality instruments.

Abstract

Physics education in the 21st century is undergoing various innovations to enhance its effectiveness and relevance in the digital era. This study aims to map current research trends in high school physics education through bibliometric analysis and SLR analysis methods on articles indexed in the Scopus database. This study utilized 62 articles on physics learning that were analyzed. The study results show that innovations in physics learning include the use of simulations and virtual reality, digital applications such as Getsmart and PhET, project-based learning (PBL) approaches, as well as the use of digital tools like Tinkercad and Arduino Uno. In addition, STEM-based learning approaches, flipped classrooms, and hybrid learning are increasingly being implemented to enhance 21st-century skills such as critical thinking, problem-solving, and creativity. This study also found that teacher training adopting the Nature of Science (NOS) approach and technology in teaching contributes to the improvement of pedagogical competence. Learning evaluations using HOTS-based instruments and technology-based e-assessments have proven effective in measuring students' understanding and interest in physics.

Abstract

In modern physics education, digital literacy has shifted from a supplementary skill to an essential competency for meaningful scientific inquiry. However, despite widespread access to digital technology, many students still demonstrate limited academic digital literacy, especially in physics learning contexts. This study aims to examine the effects of an interactive physics e-book integrated with the STEM 5E learning cycle and the local wisdom of geblek-making on students’ digital literacy profiles. A quasi-experimental pretest–posttest control group design was used, involving 108 grade X students divided into an experimental group (STEM-5E e-book), a contrast group using a 3E e-book, and a contrast group using traditional textbooks. Students’ digital literacy, including information literacy, media literacy, and ICT literacy, was measured with a validated 14-item multiple-choice test and analyzed using Aiken’s V and Rasch modeling. Results show that the experimental group achieved the greatest improvement, with a mean normalized gain of 67.33% (moderately effective), outperforming the 3E group (55%) and the traditional group (44.67%). Information literacy showed the most notable improvement, reaching an effective category with an 82% increase. Rasch-based profile analysis also revealed the complete removal of low levels of digital literacy in the experimental group. The novelty of this study lies in its integration of ethnoscience with the STEM-5E framework via an interactive digital medium, positioning digital literacy as a culturally rooted skill. In conclusion, the findings show that combining inquiry-based learning, interactive digital tools, and local wisdom offers an effective way to enhance students’ digital literacy and provides a strong pedagogical model for developing 21st-century skills in physics education.

Abstract

This study addresses the lack of specialized diagnostic instruments capable of pinpointing specific cognitive failures in physics data literacy, particularly within Thermodynamics. To bridge this gap, a Distractor-Based Cognitive Diagnostic Test (DB-CDT) was developed and validated for eleventh-grade high school students in Yogyakarta. Utilizing a Research and Development (R&D) approach with the ADDIE framework, the instrument was built upon the DINA (Deterministic Input, Noisy-AND Gate) cognitive diagnostic model. Expert validation by three specialists yielded an excellent average V-Aiken value of 1.00. Empirical testing on a sample of 540 students across high, medium, and low-tier schools confirmed high psychometric quality: an average INFIT MNSQ of 1.00 (within the 0.77–1.30 range), item difficulty between -2 and +2, and high reliability (0.92). DB-CDT distinguishes itself by using a Q-Matrix to link specific distractors to cognitive errors, such as failures in sign conversion or process interpretation. Analysis of student profiles revealed that the experimental group—utilizing targeted diagnostic feedback—achieved superior mastery in analyzing (96.6%) and interpreting data (90%), whereas the control group, receiving conventional assessment, struggled significantly with inference and synthesis. Theoretically, this research advances the application of Cognitive Diagnostic Models in physics education. Practically, it provides educators with a sensitive tool to profile individual student weaknesses, allowing for more focused instructional interventions in complex scientific topics.
