Abstract

The Mendeley application is a supporting tool for writers creating manuscripts for publication. Teachers need publications to improve their career path, especially achieving credit scores for promotion to functional positions. This program aims to train teachers in using the Mendeley application to make it easier to create publication manuscripts. Training activities were carried out by presenting ten teachers from PGRI Palu City, Central Sulawesi and two trainers. At the first meeting on July 23 2022, the teachers' ability to use this application was identified, and it was found that almost all teachers needed to be proficient in using it. Training is then carried out using presentation, demonstration, practice and question-and-answer methods. Next, three trainers guided the participants to recognize and apply their obtained information. At the second meeting on July 26 2022, participants completed citations on the manuscript created using the Mendeley application. Assistance is provided by the service team in language that is easily understood by the participants and immediately produces output in the form of a script. This training activity was carried out over two meetings, and the results of the final evaluation showed that the participants who were initially unable to use the Mendeley application (pretest) were then able to use the Mendeley Program well (posttest). It is hoped that the implications of this activity will help participants prepare research results manuscripts to help collect credit.

Abstract

Teachers have commonly utilized existing online educational games to create more engaging learning experiences. However, their digital competence in developing online educational games remains insufficiently developed. QuizWhizzer is one of the digital applications that can be used to create online educational games. Therefore, this community service program aimed to (1) train teachers to use the QuizWhizzer application in developing online educational games, (2) improve teachers’ digital competence, and (3) examine teachers’ responses to the training program. The participants consisted of 34 teachers from SMPN 6 Palu. The program was conducted through three stages: preparation, implementation, and evaluation. The training activities included lectures, demonstrations, and hands-on practice in using the QuizWhizzer application. The results showed that the average pre-test score of teachers’ digital competence was 53.33, while the average post-test score increased to 72.94, with a normalized gain score of 0.44. In addition, 94.12% of the participants successfully completed the practical assignment of developing online educational games using QuizWhizzer. The average score of teachers’ responses to the training was 4.65, indicating a highly positive perception. Based on these findings, it can be concluded that (1) the teachers were successfully trained to use QuizWhizzer for developing online educational games, (2) their digital competence improved at a moderate level, and (3) they expressed highly positive responses toward the training program.

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

Critical thinking skills are important in physics education because they encourage students to analyze, evaluate, and apply concepts in real life. However, the assessment instruments used still focus on memory skills and have not integrated the local cultural context. In fact, many physical phenomena, including heat transfer, can be seen in cultural activities such as traditional food preparation. Previous studies have emphasized the development of questions based on higher-order thinking skills, literacy, and numeracy, but few have linked them to culture. Therefore, it is necessary to develop ethno-physics-based critical thinking questions on heat so that assessments not only measure conceptual mastery but also connect physics with local wisdom. This study aims to analyze the validity, reliability, discriminating power, and difficulty level of ethno-physics-based critical thinking questions on the topic of heat, as well as to test their practicality. The method applied is Tessmer's Research and Development (R&D) model, with stages including Preliminary, Self-Evaluation, and Formative Evaluation. The results of the development show that the resulting test items are valid. The reliability value obtained is 0.75, which is classified as high. In terms of difficulty, the majority of questions are categorized as moderate and a small portion are easy. The discrimination power of the test items varies between very good, good, and fair. Overall, all items successfully differentiated between students' abilities, and none of the items failed to differentiate. In terms of practicality, the use of these items is classified as very practical.

Abstract

Penelitian ini memiliki tujuan untuk menganalisis pengaruh model belajar mengajar Cooperative Learning berbantuan Lembar Kerja Peserta Didik (LKPD) terhadap hasil belajar peserta didik pada materi suhu dan kalor. Penelitian ini memanfaatkan pendekatan kuasi-eksperimen dengan rancangan Non-equivalent Pretest-Posttest Control Group Design yang melibatkan 44 peserta didik kelas VII di MTs Alkhairaat Dolo, terbagi atas kelas eksperimen serta kelas kontrol. Pengambilan data dilaksanakan melalui tes hasil belajar berbentuk soal esai (pretest maupun posttest). Analisis data memanfaatkan uji ANOVA dan uji N-Gain. Temuan uji ANOVA pada data pretest menggambarkan tidak adanya perbedaan kemampuan awal yang signifikan (F = 0,931; α = 0,340 > 0,05), sedangkan pada data posttest terdapat perbedaan hasil belajar yang signifikan antara kedua kelompok (F = 8,795; α = 0,005 < 0,05). Rata-rata N-Gain kelas eksperimen sebesar 39% dan kelas kontrol sebesar 23,75%, di mana berdasarkan klasifikasi Wiyono (2020) kedua perolehan tersebut berada pada kategori tidak efektif (<40%). Namun demikian, penerapan model pembelajaran kooperatif berbantuan LKPD memberikan peningkatan hasil belajar yang lebih baik dibandingkan dengan pembelajaran langsung.
