Abstract

The covid-19 pandemic has changed educational policies regarding learning and teaching methods that were initially conventional and must now be integrated with technology. It takes teaching materials that can help students in learning. This study aims to develop an E-student worksheet using the Canva-assisted learning of inquiry sequences (LOIS) learning activity model that can be applied as a physics learning material that can practice hands-on skills, mind-on activities, and science process skills. This study uses research and development research methods. The E-student worksheet development procedure uses the ADDIE development model. The results of the experts show that the average score of the assessment of the E-student worksheet is 3.58, which is included in the very valid criteria. The limited trial of the E-student worksheet on the teacher's perception obtained results of 91% in the very good category, the test results for class XI students could be applied with a very good 88% score. The results of the effectiveness of working on the E-student worksheet obtained an average score of 89% in the highly trained category. It can be concluded that which means the E-student worksheet can train hands-on, minds-on activity, and science process skills.

Abstract

The urgency of this research stems from the lack of application of the Ethnoscience-STEM-PjBL (Science, Technology, Engineering, and Mathematics - Project-Based Learning) approach in renewable energy learning, the limited availability of teaching materials based on local wisdom, and the lack of supporting learning resources. This study aims to describe the perceptions of teachers and students toward renewable energy learning using this approach to foster creativity and entrepreneurial skills. This research employed the sequential embedded design method, involving 30 physics teachers from Lampung Province. Data were gathered through questionnaires and analyzed descriptively. The findings reveal that while teachers generally hold positive perceptions of the Ethnoscience-STEM-PjBL approach, most have yet to implement it in their classrooms. The implication of this study highlights the urgent need to develop culturally relevant teaching materials and provide targeted teacher training. Such efforts are essential to facilitate the effective integration of the Ethnoscience-STEM-PjBL model in renewable energy education, thereby enhancing both student engagement and the relevance of science learning in local contexts.

Abstract

Scientific argumentation is a critical 21st-century skill that must be systematically integrated into science education, particularly physics. However, current classroom assessments rarely comprehensively and in-depth measure students’ argumentation skills. This study aims to analyze the need to develop a multi-representation assessment instrument supported by the Thunkable application to evaluate students’ scientific argumentation skills on static fluid concepts. A mixed-method approach with an embedded sequential design was employed. Quantitative data were collected through questionnaires administered to 34 physics teachers and 97 eleventh-grade students from several high schools in Lampung Province, Indonesia. Besides, qualitative data were obtained through open-ended responses to explore classroom learning experiences and assessment practices further. The findings reveal that 91% of teachers reported difficulties in assessing argumentation skills, while 94% of students faced challenges in connecting static fluid concepts across different representations. The use of multi-representation tasks in assessments was found to be limited. Nevertheless, teachers and students expressed strong interest in using interactive digital assessment tools. These findings highlight the strategic opportunity to develop a Thunkable-assisted, multi-representation-based assessment instrument that addresses teachers’ and students’ needs and improves assessment practices in physics education by promoting meaningful learning and scientific argumentation.

Abstract

Creative thinking skills are very important in the 21st century. This research aims to determine the perceptions of Natural Science teachers towards electronic student worksheets based on chicken manure waste processing projects to improve students' creative thinking abilities. This research uses mixed methods with a sequential explanatory design. Data was collected through questionnaires, then descriptive analysis was carried out. Questionnaires were distributed to 18 natural science teacher respondents and 115 junior high school students in Lampung Province. The research results show that 83% of teachers have not used project-based e-worksheets; 79% of teacher respondents have implemented Project Based Learning; while only 56% of teachers have not carried out creative thinking ability tests. Based on student response questionnaires, 82% of teachers have given project assignments, but these projects are not based on real problems in the environment. The survey results show that 86% of teacher respondents already know about creative thinking skills, but the indicators of creative thinking skills that teachers understand are different from the indicators of creative thinking skills that should be measured. Based on the research results, it can be concluded that e-worksheets based on chicken waste processing projects are needed to improve students' creative thinking abilities

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.
