Abstract

This study aims to develop a project-based pretest-posttest assessment of the use of coffee husks. This study used the research and development method of the ADDIE model until the development stage. At the analysis stage, a literature study and a preliminary study were conducted. At the design stage, planning and preparation of an initial draft in the form of a pretest-posttest assessment were carried out. In the development stage, two science education experts validated the suitability of the content and construction of the pretest-posttest assessment with Torrance's creative thinking skills indicator framework. The product of the validation results was then responded to the suitability of the content and construction aspects of creative thinking skills indicators by the three science teachers. The results of expert validation and teacher responses indicated that the pretest-posttest assessment instrument product is very suitable to be used to measure students' creative thinking skills in integrated learning based on coffee peel utilization projects.Keywords: pretest-posttest assessment, coffee peel utilization projects, creative thinking.DOI: http://dx.doi.org/10.23960/jpmipa/v23i1.pp13-24

Abstract

Creative thinking skills have an important role to face the challenges of the 21st century. This study aims to improve the creative thinking skills of junior high school students through a project-based learning model for processing cassava peel waste. This research method is quasi-experimental, non-equivalent pre-test-post-test control group design. The sample in this study was class VII students of SMPN 1 Purbolinggo, who were determined using a purposive sampling technique. The number of students in the control and the experimental classes was 32 people each. The instruments in this research are the Creative Thinking Skills Test and Performance Assessment. The results showed that the average N-gain for creative thinking skills in the experimental class was in the medium category (0.58), while on the control class, it was in the low category (0.29). Cohen's d coefficients for each indicator of creative thinking skills fluency, flexibility, originality, and elaboration; were 0.62, 0.58, 0.72, and 0.72, respectively, all in the medium category. However, Cohen's d coefficient effect size for the average N-gain overall creative thinking skills is 2.40, belonging to the very large category. Based on these results, it can conclude that the project-based learning model is effective with a very large effect on improving students' creative thinking skills.Keywords: creative thinking skills, project-based learning models, cassava peel waste.DOI: http://dx.doi.org/10.23960/jpmipa/v23i4.pp1850-1861

Abstract

Development and Validation of ADI-STEM-Based Biotechnology e-Liveworksheets to Enhance Student Argumentation Skills. Objectives: Despite its enormous potential, ADI-STEM-based electronic worksheets are still rarely used. In the face of the challenge of integrating STEM, ADI-based worksheets should be centered on authentic engineering issues. Designing real-world, challenging, yet still solvable problems for students with digital tools (Technology & Math) and relevant Science concepts. The purpose of this study is to fill this gap by developing and validating a reliable teaching material called the ADI-STEM-Based Biotechnology e-Liveworksheets (ASBL), which is intended to train the argumentation skills of Indonesian junior high school students. Methods: The research employed a development method using the Thiagarajan 4-D model, which includes the stages of Define, Design, and Develop, without the Disseminate stage. The ASBL underwent rigorous validation by experts and field testing in junior high school students in Indonesia. The Sampson & Clark framework is used to measure students' argumentative skills. Two biology education experts reviewed the content to ensure its validity. Two media experts reviewed the content to ensure its validity, and a senior teacher assessed the feasibility and practicality of ASBL. Researchers got real-world data for descriptive-quantitative analysis from 30 9th-grade students at a junior high school in Lampung, Indonesia. This data demonstrates the practicality of teaching materials, as evidenced by the increase in the average value of argumentation skills between before and after learning, as well as the responses of educators and students to the learning process. Data were collected using validated questionnaires and written tests. Findings: The results of the study showed that the ASBL was stated as very high validity (93%) by material experts, high validity (87%) by media experts, very practical to uses in learning by students (98%), with in improving students’ argumentation skills with N-gain in the high cateogry of claim (0,82), evidence (0,78), and reasoning (0,79). The majority of students (over 85%) found ASBL easy to use, engaging, and helpful in guiding their learning process. Teachers reported that the platform enabled efficient progress tracking and assessment of students’ argument construction at each learning phase. Conclusion: This research develops valuable and valid teaching materials to train students' argumentation skills. As a teaching material that aligns with the Independent Curriculum, ASBL is quite useful for Indonesian teachers. This encourages a shift from memorizing things by rote to understanding them more deeply and learning how to conduct science. Future research could explore scaling this model across different science topics, educational levels, or through longitudinal studies to assess retention and transfer of argumentation skills.     Keywords: biotechnology, liveworksheets, argumentation, argument-driven inquiry, STEM.

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.
