Abstract

Teaching materials in their role as providers of information are really needed by educators and student. The purpose of this research is to develop teaching materials in the form of e-LKPD with a scientific approach to static fluid material to improve critical thinking skills at SMAN 9 Merangin which can be used in the learning process. This development research uses a 4D development model. The test subjects consisted of a small group consisting of 10 people and a large group consisting of 30 people who were students of SMAN 9 Merangin. The instruments used in this research were interviews, questionnaires, pretest-posttest questions, and validation assessment sheets. The data analysis technique used in this research is descriptive research with a quantitative approach. The validation results from material and media experts show that the teaching materials developed are very valid for small group trials. Teacher assessments and student responses to the media are very good. The effectiveness of e-LKPD teaching materials in improving critical thinking skills was carried out by a Paired Sample T-Test with the decision that the hypothesis was accepted and a large group test was carried out to obtain a fairly effective level of effectiveness with an average value of 0.6187 or 61.8696%. It can be concluded that the development of e-LKPD teaching materials with a scientific approach to static fluid material to improve critical thinking skills is feasible and effective for use in the learning process. 6187 or 61.8696%.

Abstract

This study aims to develop and validate a web-based five-tier isomorphic diagnostic instrument to identify students’ misconceptions on temperature and heat concepts in junior high school. This research employed a quantitative developmental approach, involving instrument development, construct validation, and descriptive analysis of students’ responses. The instrument consisted of nine multiple-choice items structured into five tiers and was validated using factor analysis (Principal Component Analysis), with all items showing factor loadings greater than 0.50. Reliability testing using Cronbach’s alpha yielded a coefficient of 0.745, indicating high internal consistency. A total of 101 eighth-grade students from SMP Negeri 12 Jambi participated in the study by completing the web-based diagnostic test. The results identified 13 types of misconceptions, with an average misconception rate of 12.56% across all tiers, indicating that although students’ overall misconceptions were relatively low, several fundamental concepts related to temperature and heat remained problematic. The most common misconception was that dividing an object divides its temperature, accounting for 36.6%. Compared to conventional one-tier or two-tier diagnostic tests, this five-tier isomorphic instrument provides more detailed diagnostic information by incorporating students’ reasoning and confidence levels. Therefore, this instrument contributes to science education research by providing a valid, reliable, and practical tool for diagnosing students’ conceptual understanding and supporting more effective instructional planning in physics.
