Abstract

Mathematical representation ability is an essential skill for students to understand mathematical concepts. Many studies have been conducted regarding this ability, but it is necessary to map existing research to provide a clearer picture of future research topics. This study aims to provide a bibliometric review of trends using mathematical representation skills in mathematics teaching research. The method in this study is bibliometric analysis, which aims to analyze and classify bibliographic material by presenting representative summaries of the literature in the Scopus database. The search was carried out using the keyword "mathematical representation" and selecting "article title" in the search menu in the Scopus.com database. Perish or Publish (PoP) software analyzes the author's name, number of document citations, document title, year of publication, document source, publisher, and document type. The results showed 99 publications and 357 citations related to mathematical representations, where the number of publications and citations fluctuated. The application of learning models and approaches, computer media, and analysis of mathematical representations is a research trend related to this variable. Therefore, paying attention to mathematical representations in learning mathematics and using effective strategies to improve students' mathematical representation abilities is essential. The findings of this study indicate the need to develop syntax and learning media based on mathematical representations to strengthen students' mathematical abilities.

Abstract

Background: Creative Problem-Solving (CPS) is a critical skill in physics education, enabling students to address real-world challenges through innovative and practical approaches. Despite its importance, there is a limited number of reliable and valid instruments specifically designed to assess CPS skills within the context of physics education.Aim: This study aims to develop and prove the validation of a CPS assessment instrument using the Rasch model to ensure its reliability and accuracy in measuring CPS skills in physics education.Method: The research followed the ADDIE development model, which includes analysis, design, development, implementation, and evaluation phases. The instrument, consisting of 20 essay items aligned with CPS indicators, was validated by three experts in physics education. It was then tested on 35 Grade XI students in Lampung Province. Data analysis was performed using the Rasch model through Winsteps software, focusing on fit analysis, reliability, item difficulty distribution, and dimensionality assessment.Results: The instrument demonstrated strong internal consistency, confirming its reliability for assessing CPS skills in physics education. The construct validity was supported by fit analysis, indicating that most items functioned appropriately. However, some items exhibited potential bias and required revision. The dimensionality analysis confirmed that the instrument effectively measured a single underlying construct, ensuring its psychometric robustness. These findings suggest that the developed CPS assessment instrument is a reliable and valid tool for evaluating students’ creative problem-solving abilities in high school physics, particularly in fluid mechanics.Conclusion: This study successfully developed and validated a CPS assessment instrument for high school physics education, demonstrating strong reliability and construct validity. The instrument effectively measures CPS skills, though some items require refinement to ensure fairness and accuracy. Future research should focus on further improving item quality and testing the instrument in diverse educational settings to enhance its applicability and generalizability.

Abstract

This study aims to determine the effect of using the Search, Solve, Create, and Share (SSCS) learning model on the scientific reasoning abilities of 12th-grade students in the topic of heredity. The sample consisted of 62 students from two classes, selected using purposive sampling. This research employed a quasi-experimental method with a non-equivalent pretest-post-test control group design. The data were analysed using an independent sample t-test at a 5% significance level. The results showed that the application of the SSCS model had a significant effect on improving students’ scientific reasoning, with a sig. (2-tailed) value of 0.000 < 0.05. The average N-Gain in the experimental class was 0.46, which falls under the medium category. The highest increase occurred in the probabilistic reasoning aspect (N-Gain = 0.42), while the lowest increase was in the combinatorial reasoning aspect (N-Gain = 0.36), both classified as medium. The effect size of the SSCS model on scientific reasoning was 1.47, which is categorized as large. Based on the questionnaire results, 78.43% of students agreed that the SSCS learning model made them more active in the learning process and helped them achieve a better understanding of heredity material. It can be concluded that the application of the SSCS model positively influences the improvement of students’ scientific reasoning skills and is well accepted by the students.Keywords: Search, Solve, Create, and Share Model; Scientific Reasoning
