Abstract

In the 21st-century learning era, the quality of teaching materials is crucial in meeting current educational needs. This study highlights the urgency of developing a science literacy-based textbook for the Earth and Space course to enhance students' scientific literacy competence in the Physics Education Study Program at Mulawarman University. The research aims to analyze the necessity of such a textbook using the 4D development model, focusing on the Define phase to identify key learning challenges and curriculum needs. Data were collected through classroom observations, student questionnaires involving 42 participants from the 2023 cohort, and the formulation of learning outcomes aligned with the three scientific literacy competencies of the Programme for International Student Assessment (PISA): (1) explaining scientific phenomena (2) evaluating and designing scientific investigations, and (3) interpreting data and scientific evidence. The data analysis process involved data reduction, presentation, and conclusion drawing. The findings indicate that the current teaching materials do not fully support the learning objectives, leading students to rely on fragmented online resources, often in English. The study also identified a strong demand for structured, interactive textbooks integrating scientific literacy. The validation process involved three expert validators using a Likert scale assessment. This validation resulted in eight valid learning outcomes (CPMK) with a corrected item-total correlation of r > 0.3 and a Cronbach's Alpha of 0.848, confirming high reliability. These findings provide a foundational framework for developing an Earth and Space textbook, ensuring its alignment with science literacy competencies in subsequent research phases.

Abstract

The availability of instructional materials that systematically facilitate students’ problem-solving processes remains a challenge in physics learning, particularly in dynamics of motion. This study aimed to develop a problem-solving-based interactive e-worksheet and determine its validity and practicality in supporting students’ problem-solving skills (PSS). The study employed a research and development approach using the Plomp development model, limited to the prototyping phase. The development process included preliminary research, prototype design, self-evaluation, expert review, one-to-one evaluation, and small-group evaluation. Data were collected through validity and practicality questionnaires involving three physics education experts, one physics teacher, and 12 students at Baiturrahmah High School. Validity data were analyzed using Aiken’s V coefficient, while practicality data were analyzed using percentage analysis. The e-worksheet obtained an average validity score of 0.84, indicating a valid category. The teacher’s practicality assessment yielded an average score of 79.17%, categorized as practical. The one-to-one and small-group evaluations obtained average scores of 90.11% and 91.09%, respectively, both categorized as highly practical. These findings indicate that the e-worksheet is clear, attractive, easy to use, and useful for facilitating structured problem-solving activities. Therefore, the developed interactive e-worksheet is valid and practical for supporting students’ PSS in physics learning
