Abstract

This study aims to analyze the feasibility of a scientific reasoning ability test instrument for prospective science teachers using the Rasch model. The instrument developed refers to Lawson's Classroom Test of Scientific Reasoning (LCTSR) indicators, focusing on scientific reasoning abilities, including variable control, combinatorial, probability, relational, and proportional thinking. The analysis was carried out using the Rasch Model with the WINSTEPS Version 5.7.3.0 application to test the validity, reliability, and characteristics of the test items. The feasibility test was carried out on 40 multiple-choice questions, tested on 110 test samples. The analysis results showed that 25 of the 40 questions were valid and covered all indicators of problem-solving skills. The test instrument also has a high level of internal consistency with a person reliability value of 0.84 and an item reliability of 0.95. Analysis of the level of difficulty of the test items showed a balanced distribution between very difficult, difficult, moderate, and easy questions. No items were detected as biased, indicating that this instrument is fair and can be used without favoring one group of individuals. Overall, the developed problem-solving skills test instrument is valid and reliable for use on prospective science teachers, assisting educators in evaluating students' problem-solving skills, providing constructive feedback, and improving the quality of learning in science.

Abstract

This research aims to validate and implement an instrument to measure the scientific literacy of high school science program students, including the abilities of Scientific Reasoning, Scientific Inquiry, and Nature of Science (NOS), called the Lisa3D Test. These three instruments were validated using the Rasch model approach and presented as a digital application. This research method was a descriptive survey with a quantitative approach. The research started from the test design, validation, and implementation stages. The types of validity used included content, psychometric, construct, and external validity. For construct validity, the instrument was tested on 197 high school students, while the implementation stage involved 407 students. The research results show that the Lisa3D Test has fulfilled all aspects of validity. The Lisa3D test has been successfully implemented via the page www.lisatest.id  with a cut of 56% for the Scientific Reasoning test, 50% for the Scientific Inquiry test, and 56.25% for the NOS test. This research produces a standard instrument to measure the scientific literacy of high school science program students based on three dimensions, namely Scientific Reasoning, Scientific Inquiry, and Nature of Science (NOS). The Lisa3D test can be implemented on a broader scale and can be an additional criterion for graduating high school students so that all graduates can master science comprehensively.

Abstract

Critical thinking skills are crucial in modern society. This research aims to provide a general overview of recent developments in research methods for measuring critical thinking skills in higher education. It is based on a bibliometric analysis of journal articles published in the Scopus database, with the goal of identifying scientific gaps and providing a reference for further research. The methodology employed includes bibliometric analysis using VOSviewer and Biblioshiny software. The results indicated a growing trend in research focused on measuring critical thinking skills. Several topics and keywords have emerged that could serve as a foundation for future studies, along with trends in research methods for assessing critical thinking skills in higher education. The research concluded that bibliometric analysis offers valuable insights into developing research on measuring critical thinking and its methods, paving the way for further investigations. Notably, topics related to undergraduate students, critical thinking skills, and active learning potentially yield significant novel contributions if explored in future research.

Abstract

Penelitian ini bertujuan untuk menganalisis peningkatan kemampuan pemecahan masalah siswa melalui model flipped calssroom dengan pendekatan saintifik berbantuan Edpuzzle. Desain penelitian yang digunakan adalah kuasi-eskperimen dengan melibatkan dua kelas VIII di salah satu SMP di Kabupaten Brebes. Instrumen yang digunakan  berupa tes uraian berdasarkan indikator Polya. Hasil analisis menunjukkan bahwa rata-rata N-Gain kemampuan pemecahan masalah pada kelas eksperimen sebesar 0,421 (katergori sedang), sedangkan kelas kontrol sebesar 0,240 (kategori rendah). Uji independent sample t-test menunjukkan perbedaaan yang signifikan antara kedua kelompok (p=0,002). Penemuan ini mengindikasi bahwa flipped classroom dengan pendekatan saintifik berbantuan Edpuzzle lebih baik dalam meningkatkan kemampuan pemecahan masalah siswa dibanding model problem based learning.

Abstract

Penelitian ini bertujuan untuk mengkaji densitas sebagai indikator degradasi minyak goreng akibat pemanasan berulang melalui pendekatan eksperimen berbasis Hukum Archimedes. Metode yang digunakan adalah eksperimen dengan pengukuran langsung terhadap tiga jenis minyak, yaitu minyak sawit, minyak kelapa, dan minyak jagung. Variabel independen berupa jenis minyak dan jumlah pemanasan (delapan siklus), sedangkan variabel dependen adalah densitas minyak. Pengukuran densitas dilakukan dengan membandingkan berat benda di udara dan di dalam minyak, dengan tiga kali pengulangan pada setiap perlakuan untuk meningkatkan reliabilitas data. Hasil penelitian menunjukkan bahwa densitas ketiga jenis minyak meningkat secara bertahap seiring bertambahnya jumlah pemanasan. Peningkatan densitas tertinggi terjadi pada minyak sawit, diikuti minyak kelapa, dan terendah pada minyak jagung. Temuan ini mengindikasikan bahwa pemanasan berulang menyebabkan degradasi kualitas minyak, yang tercermin dari peningkatan densitas. Dalam konteks parameter densitas, minyak jagung menunjukkan stabilitas yang relatif lebih baik terhadap pemanasan berulang dibandingkan minyak kelapa dan minyak sawit. Penelitian ini menegaskan bahwa densitas dapat digunakan sebagai indikator fisik yang sederhana dan aplikatif untuk menganalisis degradasi minyak goreng, meskipun interpretasinya masih terbatas pada aspek fisik dan memerlukan dukungan parameter kimia untuk evaluasi kualitas yang lebih komprehensif.

Abstract

Experts have widely discussed the concept of inclusive service, and governments in various countries have widely applied this concept. However, there is still much discrimination in the facility's people with disabilities (PWD) sector. Thus this paper aims to concept measurement models and parameters of inclusive public services to people with disabilities (PWD). The method of this paper is reviewing the previous research with a high impact score. Then the result of the data presented uses CiteSpace analysis to prioritize concept inclusive model and parameters in public services. The results of the research are the model and parameters of inclusive public services to PWD are openness, fairness, infrastructure, and responsiveness. It required content of the government services to meet the needs of PWD. The paper includes implications satisfaction for an inclusive model in the Indonesia Government and managing inclusivegb777
