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 research aims to describe students' systems thinking abilities on the main material of the Digestive System. The subjects of this research were 60 students of Junior High School 8 Bandar Lampung for the 2022/2023 academic year who were selected from a population of 275 students using a cluster sampling technique. This research uses an ex post facto design. System thinking ability data was obtained through description tests which were analyzed descriptively. The results of the research show that students' systems thinking abilities are in the sufficient category for 60% of students and in the deficient category for 40% of students. The highest systems thinking ability is in the indicator of the ability to examine the character of elements with an average value of 34.25 in the sufficient category, while the lowest systems thinking ability is in the indicator of correlating interconnections with an average value of 16.11 in the deficient category. Based on the results of data calculations, it can be concluded that in general students' systems thinking abilities are in the sufficient category.Keywords: system thinking ability, digestive system

Abstract

Creative thinking is a crucial skill that involves generating and synthesizing new ideas by analyzing existing concepts and transforming them into innovative solutions. This ability is particularly important in education, where students must apply theoretical knowledge to real-world problems. However, not all students possess strong creative thinking skills. This study aims to analyze the creative thinking abilities of Biology Education students at UIN Raden Intan Lampung, focusing on 2021. The study evaluates students' creative thinking skills using Torrance's indicators: fluency, flexibility, originality, and elaboration. A qualitative descriptive approach was employed, with data collected through purposive sampling. The findings indicate that Biology Education students fall under the "quite creative" category. Specifically, fluency scored 57%, flexibility 48%, originality 43%, and elaboration 47%, all classified as "quite creative". The results suggest that while students demonstrate moderate creative thinking skills, there is room for improvement. Educators should integrate pedagogical strategies that enhance creativity, such as problem-based learning and open-ended assignments, to foster higher-level creative thinking in biology education. This study highlights the need for further targeted interventions to develop students' creative potential.

Abstract

This study aims to develop differentiated electronic student worksheets (e-LKPD) integrated with Higher-Order Thinking Skills (HOTS) and multiple intelligences that are valid, practical, and effective in enhancing students’ systems thinking skills. The research follows the Borg and Gall R&D model. The study population comprised eighth-grade students from SMPN 1 Mesuji in the 2024/2025 academic year. A purposive sampling technique was employed to assign class VIIIA as the experimental group and class VIIIB as the control group. Data collection instruments included need analysis questionnaires, expert validation forms, student and teacher response questionnaires, pretest and posttest items, reflection sheets, and learning implementation observation sheets. Data analysis was conducted using independent sample t-tests on n-Gain scores. The findings revealed that: (1) the e-LKPD was rated as highly valid (95%) by expert reviewers; (2) it was considered highly practical by students (95%) and teachers (100%); (3) it was effective in improving systems thinking skills with a high n-Gain score (0.75) and a large effect size (0.95); and (4) it achieved a very high implementation level (87.19%). These results indicate that the developed e-LKPD is suitable for use in science learning, particularly on the topic of the digestive system, to enhance students' systems thinking skills.

Abstract

The aim of the research is to develop a peer scaffolding-based learning program to equip prospective science teacher students with the ability to develop performance appraisals. This program was developed using a 4D model (Define, Design, Develop, and Disseminate), the development of which has reached the stage of feasibility testing (Develop). Data collection techniques with questionnaires to measure the validity of the feasibility of learning programs and essay tests for the ability to develop performance appraisals. The results of this study indicate that the learning program developed got an average score of 4.00 (very valid category) in all aspects of feasibility. The results of the program trial show that there is an increase in student abilities seen from their N-gain (0.41: moderate criteria). Improvement in the aspect of the ability to understand the scope of the assessment with “low” criteria (0.036), planning an assessment with “medium” criteria (0.72). Based on this, it is concluded that the program developed is quite effective in providing performance appraisal skills for prospective science teacher students.Keywords: learning program, peer scaffolding, performance assessment.DOI: http://dx.doi.org/10.23960/jpmipa/v23i1.pp284-293

Abstract

This study aims to describe teachers' perceptions of the role of student worksheet (Hard Scaffolding) in improving HOTS and students' collaboration skills. The research was conducted in the province of Lampung, Indonesia, involving 56 science teacher respondents through the MGMP IPA forum (Science Subject Teacher Consultation). The research design is mixed methods. The mixed methods strategy used by Sequential Explanatory Design combines qualitative and quantitative data collection and data analysis. Data was taken using a questionnaire that was distributed using a Google form. The survey results show that teachers have a positive perception of student worksheet (hard scaffolding) to improve students' higher-order thinking skills and collaboration skills. Based on the results of an analysis of the use of student worksheet in schools, most teachers have not used student worksheets that are able to train students to achieve competence optimally. The scaffolding strategy in science learning can help the learning process where students are given some assistance during the early stages of learning and then reduce this assistance and provide opportunities for students or students to take over greater responsibility after being able to do it on their own so as to be able to involve students. actively in a learning process that is oriented to equip students with higher-order thinking skills and collaboration skills.
