Abstract

mental models regarding the apparent motion of the Sun and stars. The method used is a qualitative approach with an exploratory descriptive study using the reflective thematic analysis method according to Braun, Clarke, and Rance (2014). The subjects of this study were ChatGPT and Gemini, who also acted as respondents. The instrument used was 10 multiple-choice questions about the apparent motion of celestial bodies. Each answer was analyzed thematically to identify reasoning patterns, conceptual structures, and conformity with scientific mental models. The results show that ChatGPT predominantly displays a scientific mental model consistent with a heliocentric understanding and scientific explanation of apparent motion, while Gemini tends to display a hybrid mental model with a mixture of scientific concepts and preconceptions. The comparison of the two shows differences in conceptual depth, consistency of reasoning, and accuracy of scientific representation. These findings contribute to the development of the study of artificial intelligence mental models and open up opportunities for their use in AI-based science learning

Abstract

Assessment in physics education requires valid and reliable measurement instruments capable of accurately representing students’ cognitive abilities, including conceptual understanding, scientific reasoning, and problem-solving skills. Over the past decades, instrument validation has shifted from Classical Test Theory to modern probabilistic measurement models, particularly Item Response Theory (IRT) and the Rasch model. Despite the growing application of these models in physics education research, the expanding literature remains thematically and methodologically fragmented, limiting a comprehensive understanding of the field’s intellectual development. Therefore, this study aims to map the intellectual structure and research trends of IRT and Rasch model applications in physics education assessment. This study employed a bibliometric research design using 243 Scopus-indexed publications published between 2001 and 2026. Bibliographic metadata were retrieved using Publish or Perish and analyzed using the Bibliometrix package in RStudio and VOSviewer to examine publication trends, influential sources, collaboration networks, and keyword co-occurrence patterns. The results reveal substantial growth in publications, increasing by more than 1,150% over the past two decades. Five major thematic clusters were identified: measurement frameworks, psychometric modeling, validity and fairness, instrument development and technology, and learning progression. Emerging themes such as computational thinking, digital instrument development, and multidimensional assessment indicate a shift toward competency-based and technology-supported assessment practices. Overall, the findings reveal the intellectual structure and research trends of IRT and Rasch model applications in physics education assessment, demonstrating their growing role as central methodological frameworks in contemporary assessment research. These findings also provide directions for future research, particularly in developing multidimensional Rasch-based instruments and technology-enhanced assessment systems in physics education

Abstract

Penelitian ini bertujuan untuk meningkatkan pemahaman konsep fisika pada materi fluida statis dengan menerapkan model pembelajaran berbasis pengalaman dengan bantuan Physics Education Technology (PhET). Jenis penelitian yang digunakan yaitu penelitian kuantitatif dengan desain kuasi eksperimen dan menggunakan model nonequivalent control group design. Subjek dalam penelitian ini ditentukan menggunakan teknik non random sampling dengan jenis purposive sampling. Sampel penelitian adalah siswa kelas XI IPA 3 yang berjumlah 33 orang dan XI IPA 4 yang berjumlah 32 orang. Siswa kelas XI IPA 3 sebagai kelas eksperimen yang diberikan perlakuan pembelajaran berbasis pengalaman berbantuan simulasi interaktif PhET, sedangkan kelas XI IPA 4 sebagai kelas kontrol yang diberi perlakuan model pembelajaran konvensional. Skor rata-rata pretest pada kelas ekseprimen 48,13 dan kelas kontrol 44,0. Skor rata-rata posttest pada kelas eksperimen 80,19 dan kelas kontrol 73,65 dari skor ideal 100. Berdasarkan uji hipotesis menggunakan uji-t dua pihak dengan taraf signifikan 5% diperoleh nilai = 3,04 =1,99. Hal ini menunjukkan bahwa ditolak dan diterima, dengan demikian dapat disimpulkan bahwa terdapat perbedaan pemahaman konsep fisika antara kelas yang diberikan perlakuan berupa model pembelajaran berbasis pengalaman dengan bantuan media PhET interactive simulation dengan kelas yang menerapkan model pembelajaran konvensional. Uji dampak (effect size) diperoleh sebesar 0,70 masuk dalam kategori sedang. Hasil uji N-gain diperoleh nilai rerata peningkatan pemahaman konsep siswa pada kelas eksperimen senilai 61,80% kategori sedang dan kelas kontrol senilai 52,94% kategori sedang.

Abstract

Penelitian ini bertujuan untuk mengetahui bagaimana kualitas madu berdasarkan parameter massa jenis, indeks bias dan tegangan permukaan sebagai alternative pembelajaran. Metode penelitian yang digunakan adalah penelitian experiment research (Penelitian eksperimen). Teknik analisis yang digunakan adalah analisis statistik deskriptif. Sampel penelitian ini adalah madu flora yang berasal dari peternakan madu flora di Kota Palu dengan jenis madu multiflora dan madu monoflora. Hasil dari penelitian ini menunjukkan kualitas madu yang paling tinggi sampai yang paling rendah berdasarkan parameter massa jenis, indeks bias dan tegangan permukaan secara beturut – turut adalah madu multiflora dengan massa jenis sebesar 1,23 × 103 kg/????3 , indeks bias sebear 1,26 dan tegangan permukaan sebesar 9,12 × 10-5 ????/???? kemudian madu monoflora dengan massa jenis sebesar 1,13 × 103 kg/????3 , indeks bias sebear 1,16 dan tegangan permukaan sebesar 7,23 × 10-5 ????/????. Nilai SNI yang terdaftar di BPOM untuk massa jenis madu adalah 1331,25 kg/m3 dan indeks bias sebesar 1,475 – 1,504. Hal ini menunjukkan bahwa hasil dari penelitian ini menunjukkan bahwa madu yang diteliti belum sesuai dengan SNI yang dikeluarkan oleh BPOM.

Abstract

This study aims to determine the relationship between interest (X1) and critical thinking skills of seventh-grade students in science learning at SMP Negeri 4 Tanantovea. This study is a descriptive correlational study. The research sample was selected using total sampling, comprising all seventh-grade students from two classes, totalling 36 students. The instruments used in this study were a questionnaire on students' interest in learning and a critical thinking test. The questionnaire on interest in learning and the critical thinking test were subjected to content and construct validity tests. A field trial was conducted with 36 students, comprising 19 female and 17 male students. The instruments used in this study were a critical thinking test and a questionnaire on students' learning interests. The questionnaire on learning interest consisted of 20 statements, while the critical thinking test consisted of 10 essay questions. All instruments underwent content validity testing by experts, empirical validity testing using Pearson product-moment correlation, and reliability testing using Cronbach's Alpha. Prerequisite tests were conducted using the Shapiro-Wilk normality and linearity tests with SPSS 22 software. The study results in Grade VII of junior high school concluded a relationship between interest and critical thinking ability, with a correlation value of 0.402 and a regression equation of Ŷ = Y = 57.813 + 0.165X1. Furthermore, based on the calculated r value of 0.442, the criteria for the strength of the relationship between the variables of interest and critical thinking indicate a fairly strong relationship.

Abstract

Literacy, numeracy, and school safety are key aspects that shape students' learning experiences. Although these components are important, their relationships are rarely studied simultaneously. This study analyzes the relationship between literacy and numeracy skills and school safety climate in junior high schools (SMP) and Islamic junior high schools (MTS) using a quantitative correlational design with data from the 2024–2025 Education Report. A total of 52 schools were included through total sampling, and data were analyzed using descriptive statistics, Spearman correlation, and binary logistic regression. Results indicate that literacy, numeracy, and school safety vary across schools. Literacy was not significantly associated with school safety (ρ = 0.173; p = 0.221). Numeracy skills showed a significant positive relationship (ρ = 0.418; p = 0.002) and increased the likelihood of a school having a good safety climate (p = 0.005; Exp(B) = 8.393), although the contribution was small (1.7%). These findings suggest that numeracy skills can support a safer school environment.
