Abstract

Student engagement in physics assessment can be evaluated through both final outcomes and the fundamental problem-solving process. This study seeks to examine the correlation among item complexity, completion time, and student performance on a physics mechanic’s test. The research utilized a quantitative methodology through a cross-sectional survey design with 50 participants from the physics education program. Data were collected through a web-based, computer-administered assessment comprising 20 two-tiered items covering kinematics, dynamics, momentum and impulse, as well as work and energy topics. The complexity of the item was assessed according to the number of competencies engaged, encompassing conceptual, mathematical, graphical, data-related, and inter-variable relationships. The findings demonstrate that higher item complexity is associated with longer completion times, which may reflect greater cognitive effort or increased cognitive load. This increase in time did not correlate with enhanced performance; instead, it indicated a pattern toward decreasing scores, exhibiting a negative correlation of -0.32 between complexity and scores. Moreover, the correlation between completion time and performance fluctuates based on the subject matter and type of competency. Mathematical competencies demonstrate the most effective pattern, characterized by high scores and relatively brief completion times, while graphical competencies are associated with longer completion times and lower scores. The findings indicate that response time signifies both engagement and the difficulty level encountered by students.  Consequently, integrating response time with performance data provides a more comprehensive understanding of student engagement. This research underscores the necessity of enhancing representational competencies and employing process-based data to create more effective physics assessments.

Abstract

This study investigated high school students’ collaborative skills through self-assessment in a renewable energy project-based learning (PBL) endeavor. A descriptive quantitative approach was applied, involving 75 students engaged in a project on renewable energy. Data were collected using the Collaboration Self-Assessment Tool (CSAT), which consists of 11 Likert-scale items covering interpersonal and intrapersonal domains, along with three open-ended reflection questions. The data were analyzed using the Rasch model with Winstep version 5.10.1.0 to examine the instrument’s quality and students’ responses. The findings show that the CSAT meets key measurement criteria, including acceptable unidimensionality (39.3% variance explained) and good reliability (person reliability = 0.76, item reliability = 0.90, Cronbach’s alpha = 0.81). Most items functioned well, although the Wright Map indicates that the instrument was relatively easy for the students. In terms of performance, students scored higher in intrapersonal skills (82.9%) than in interpersonal skills (77.5%). Most students were categorized at the established level of collaboration, while smaller proportions were at developing and emerging levels. Responses to open-ended questions further suggest that students were able to reflect on their roles and identify ways to improve their collaboration. Overall, CSAT can be used as a practical tool to assess collaborative skills in PBL settings. The results also point to the need for strengthening interpersonal aspects of collaboration and developing more challenging items for future use.

Abstract

Penelitian ini bertujuan untuk menganalisis kualitas pengukuran instrumen Force Concept Inventory (FCI) berdasarkan model Rasch serta memetakan miskonsepsi siswa pada materi gaya dan gerak. Penelitian ini menggunakan pendekatan kuantitatif deskriptif dengan melibatkan 62 siswa sekolah menengah atas yang telah mempelajari konsep dasar mekanika. Instrumen yang digunakan terdiri atas 30 butir soal pilihan ganda, dan data dianalisis menggunakan perangkat lunak Winsteps untuk mengevaluasi kualitas instrumen serta pemahaman konseptual siswa. Hasil penelitian menunjukkan bahwa FCI memiliki kualitas pengukuran yang baik, ditunjukkan oleh terpenuhinya unidimensionalitas (22,6%), kesesuaian butir yang memadai, serta reliabilitas yang cukup baik (reliabilitas item = 0,85; reliabilitas person = 0,51). Nilai item separation sebesar 2,41 menunjukkan variasi tingkat kesulitan butir yang baik, sedangkan nilai person separation sebesar 1,01 menunjukkan bahwa variasi tingkat kemampuan siswa masih terbatas. Namun demikian, performa siswa secara keseluruhan masih rendah, dengan rata-rata persentase jawaban benar hanya sebesar 21%, yang mencerminkan rendahnya pemahaman konseptual dan adanya miskonsepsi yang cukup signifikan. Analisis lebih lanjut menunjukkan bahwa siswa cenderung mengaitkan gerak dengan keberadaan gaya secara terus-menerus serta menghubungkan arah gerak dengan besar gaya yang bekerja. Selain itu, siswa juga mengalami kesulitan dalam memahami independensi komponen gerak pada kinematika, khususnya pada konsep gerak peluru. Temuan ini menunjukkan perlunya pendekatan pembelajaran yang menekankan pemahaman konseptual dan keterpaduan konsep-konsep fisika untuk membantu mengurangi miskonsepsi siswa secara lebih efektif.

Abstract

This study aimed to analyze the quality of a conceptual understanding test instrument on renewable energy using the Rasch measurement model. The instrument consisted of 19 multiple-choice items developed based on the conceptual understanding dimensions proposed by Anderson and Krathwohl (2001) and was administered to 75 tenth-grade senior high school students. Data were analyzed using MINISTEP version 5.10.3.0, including content validity (Aiken’s V coefficient), construct validity (unidimensionality, outfit MNSQ, ZSTD, and Point Measure Correlation), reliability, item difficulty, Differential Item Functioning (DIF), and the Wright Map. The results showed that 14 of the 19 items were content valid (V ≥ 0.80). The raw variance explained by measures was 36.5%, indicating that the instrument satisfied the unidimensionality assumption. The analysis also revealed a person reliability of 0.71 (acceptable), an item reliability of 0.94 (very good), and a Cronbach’s alpha (KR-20) of 0.77 (very good). Three items (S7, S10, and S19) exhibited significant Differential Item Functioning (DIF) based on gender. The Wright Map indicated that the mean student ability was 1.14 logits, while item difficulty ranged from −2.15 to 3.33 logits. Overall, the instrument was considered suitable for measuring students’ conceptual understanding of renewable energy after revisions were made to the problematic items.

Abstract

Critical thinking is a core competency required in 21st-century education, but a valid and reliable instrument for assessing this skill within the topic of rotational dynamics remains limited. This study aims to develop and validate a critical thinking skills assessment instrument for senior high school students on the topic of rotational dynamics, employing the Rasch model for comprehensive validation. Instrument development followed the ADDIE model, involving 34 students during the implementation and evaluation phases. The instrument comprises 27 items constructed based on Facione's critical thinking aspects. Content validity analysis yielded a mean Aiken's V of 0.93, exceeding the critical threshold of 0.80. Unidimensionality testing revealed a raw variance explained by measures of 28.9% (>20%), with unexplained variance in contrasts 1–5 of the PCA residuals ranging from 5.8% to 9.9% (<15%), indicating that the instrument consistently measures a single construct. Twenty-six of the 27 items demonstrated fit to the Rasch model. Reliability analysis yielded an item reliability of 0.81 (good), a person reliability of 0.68 (fair), and a Cronbach's Alpha of 0.72 (good). Wright Map and Item Characteristic Curve (ICC) analyses further confirmed the alignment between item difficulty levels and student ability levels. The developed instrument is demonstrated to be valid and reliable for measuring critical thinking skills among senior high school students in the context of rotational dynamics.

Abstract

Problem-solving ability is one of the essential 21st-century competencies that students must develop. However, a preliminary study conducted at a public senior high school revealed that students' problem-solving ability remained low, with an average score of 42.32, far below the minimum mastery criterion (78), due to teacher-centered learning practices. This study aimed to analyze the improvement and effectiveness of the Problem Based Learning (PBL) model assisted by the IMOGLOW Flipbook E-Module digital media in enhancing students' problem-solving ability on the topic of Global Warming, as well as to examine students' responses to its implementation. This research employed a quantitative approach using a quasi-experimental method with a non-equivalent control group design. The participants consisted of 60 tenth-grade science students (30 students in the experimental class and 30 students in the control class), selected through convenience sampling. Data were collected using pretests, posttests, and a Likert-scale response questionnaire. The data were analyzed using the N-Gain test, prerequisite tests (Shapiro-Wilk and Levene's tests), the Mann-Whitney U test, and Cohen's d effect size with IBM SPSS Statistics version 26. The results indicated that the experimental class achieved a higher average N-Gain score (61.78%, moderately effective) than the control class (42.99%, less effective), with an Asymp. Sig. (2-tailed) value of < 0.001 and a Cohen's d effect size of 1.272, indicating a very large effect. In addition, students showed highly positive responses toward the learning implementation (89.17%, very good). The study concludes that integrating the Problem Based Learning model with the interactive IMOGLOW Flipbook E-Module is effective in improving students' problem-solving ability on the topic of Global Warming.

Abstract

Problem-solving ability is an essential competency in physics learning; therefore, a high-quality assessment instrument is required to measure students' abilities accurately. This study aimed to analyze the quality of a physics problem-solving ability instrument on the topic of temperature and heat using the Rasch Model. This research employed a quantitative approach with a descriptive research design involving 54 senior high school students (26 males and 28 females). The instrument consisted of five essay questions comprising 25 scored sub-items based on Heller's problem-solving indicators. Data were analyzed using Ministep version 5.10.3 software by examining item validity, reliability, item discrimination, item difficulty, Differential Item Functioning (DIF), and the Wright Map. The results showed that 21 sub-items met all item fit criteria, while four sub-items met two of the three criteria. The instrument demonstrated good psychometric quality with a Cronbach's Alpha of 0.89, Person Reliability of 0.88, and Item Reliability of 0.96. Item discrimination was generally good, only four sub-items were identified with DIF, and the Wright Map indicated good targeting between students' abilities and item difficulty. Therefore, the instrument is valid, reliable, fair, and suitable for measuring students' problem-solving ability. It can also serve as an alternative assessment tool for teachers and researchers in physics education.

Abstract

Global warming constitutes a critical topic that must be understood by students, given its far-reaching impacts on the environment, human life, and planetary sustainability. Students’ attitudes and responses toward the causes, consequences, and mitigation strategies of global warming play a pivotal role in fostering ecological awareness and promoting environmentally responsible behavior from an early age. This study aims to explore students' attitudes toward global warming in the context of physics education, focusing on their understanding of the issue and its impact on their perspectives on related policies and actions. This study employed a quantitative approach involving 40 tenth-grade students from a senior high school in Indonesia who were studying under the Kurikulum Merdeka. Data were collected using a 4-point Likert scale that measured students' attitudes towards seven main aspects related to global warming. The results showed that the majority of students have a positive attitude towards integrating material on global warming into physics learning and demonstrate awareness of the importance of addressing this issue. However, there are differences of opinion regarding policies on the use of fossil energy and alternative energy. Some students still show a conservative attitude towards fossil energy policies, while others support the policy of using alternative energy that is more environmentally friendly. This study provides important insights into the importance of integrating environmental issues in physics education and its role in shaping a younger generation that is more aware of climate change. The findings are expected to contribute to the development of educational programs that are more relevant and meaningful in raising environmental awareness and sustainability among students.
