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

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

The PRISMA-E’xi learning model integrates multiple-representation approaches, the engineering design process (STEM), and strategies designed to enhance students’ creative problem-solving skills. This study aimed to evaluate the model’s practicality through an initial implementation in senior high school physics instruction. A quantitative descriptive design was employed at the developmental research limited-trial stage, involving one tenth-grade class at SMA Gajah Mada Bandar Lampung across six instructional sessions. Data were collected through validated observation sheets assessing model implementation, teacher performance, and student activities, as well as questionnaires measuring teacher and student responses. The findings demonstrated high practicality, with implementation scoring 91.17%, teacher performance 92.31%, and student activity 88.33%, all categorized as “Excellent.” Teacher and student responses were overwhelmingly positive, with agreement levels of 98.00% and 98.95%, respectively. Although minor technical refinements were suggested, the core structure of the model remained intact and ready for broader deployment. Overall, the results indicate that PRISMA-E’xi is highly implementable, well-received, and holds strong potential to enhance student engagement and higher-order thinking in physics learning while providing teachers with a structured framework that supports 21st-century skills development.

Abstract

This research aims to determine the influence of the Education for Sustainable Development-oriented Collaborative Problem Solving model on Critical Thinking Skills and Sustainability awareness at MAN 1 Metro in 2024/2025 on ecosystem material. The population in this study were all class X students at MAN 1 Metro. The research sample was students in class X-1 as the experimental class and X-2 as the control class with the sampling technique being purposive sampling. This research is quantitative research with a quasi-experimental design. Data collection was obtained through pretest-posttest and sustainability awareness questionnaires. The type of data used is quantitative data in the form of students' critical thinking skills and sustainability awareness. The research results show that the n gain value obtained in the experimental class and control class is in the medium category, but the experimental class has a larger number, namely 0.70. Meanwhile, the results of sustainability awareness in the experimental class showed an average of 84.44 with a high interpretation. This indicates that teachers need to adopt a collaborative and sustainability-oriented learning approach so that science education, especially biology, can be more meaningful, contextual, and relevant to environmental issues both globally and locally. Thus, the results of this study imply the need to develop learning strategies that position students as critical problem solvers who have sustainability awareness to achieve sustainable development goals (SDGs) through education. So it can be concluded that there is an influence of the Collaborative Problem Solving model oriented towards Education for Sustainable Development in improving critical thinking skills and Sustainability Awareness students. The implications of the results of this study indicate that the application of Collaborative Problem Solving oriented towards Education for Sustainable Development can be an effective learning strategy to improve critical thinking skills while fostering sustainability awareness in students, so that it is relevant to be applied in 21st century education.

Abstract

Despite the importance of critical thinking in science education, junior high schools often lack effective instructional models that engage students with real-world environmental issues. One such issue, fish waste management, remains underutilised as a learning context, despite its relevance to local communities. This study investigates the effectiveness of project-based learning (PjBL) assisted by e-worksheets in fostering students’ critical thinking skills through the topic of fish waste processing. A quasi-experimental design was employed, involving 30 seventh-grade students in Bandar Lampung, Indonesia. Pre- and post-tests were administered to measure five core indicators of critical thinking: problem identification, information sourcing, hypothesis formulation, clarification, and solution generation. The results, analysed using SPSS 25.0, showed significant improvements across all indicators. For instance, accurate problem identification responses increased from 0% to 47%, and logical hypothesis construction improved from 0% to 37%. Students also reported greater engagement with the digital worksheets, which featured multimedia content, simulations, and open-ended questions. The findings indicate that e-worksheet-assisted PjBL is an effective pedagogical strategy for enhancing students’ analytical thinking, environmental literacy, and meaningful learning engagement across science education contexts.
