Abstract

Effective instruction of fluid concepts in physics requires a deep understanding of students' preconceptions and the implementation of pedagogical strategies that promote conceptual change. This study aims to develop the Electronic Conceptual Development and Conceptual Change Text (E-CDCCText), a digital instructional resource designed to foster conceptual change in students’ understanding of fluid mechanics. Employing the Design and Development Research (DDR) methodology, the development followed the ADDIE model. Validation by five expert reviewers, supported by analysis using Facet software, confirmed the material’s quality in terms of content accuracy, structural coherence, narrative clarity, and media design. The E-CDCCText comprises seven structured sections that guide students through a systematic process of constructing and reconstructing scientific concepts, integrating both conceptual development and conceptual change frameworks. The content targets three core fluid concepts: hydrostatic pressure, buoyant force, and the principles underlying floating, suspending, and sinking. The implementation phase involved 64 tenth-grade students, whose conceptual understanding was assessed using a validated four-tier diagnostic test. Results demonstrated a significant enhancement in students’ scientific conceptions, indicating the efficacy of the E-CDCCText in reducing misconceptions. In conclusion, the E-CDCCText is a validated and effective digital instructional tool for supporting conceptual change and improving students’ understanding of fluid concepts in physics education.Keywords: conceptual change, E-CDCCText, fluid concept, instructional material

Abstract

This research aims to identify the conception of Central Javanese students on fluid pressure. The survey was conducted in Central Java involving 515 participants (eight grade students about 14 years old) consisting of 177 males and 338 females. The instrument consists of six questions in a four-tier format about fluid pressure and is distributed via Microsoft Form. The analysis was carried out with Rasch analysis and percentages with six categories of conceptions: CU (Conceptual Understanding); PP (Partial Plus); PM (Partial Minus); NU (No Understanding); MC (Misconception); and NC (No Coding). The Rasch analysis shows the Cronbach alpha is 0.68 (Enough) and the distribution of students' conceptions of fluid pressure forms a normal curve. Meanwhile, bias was not found for gender problems in answering the questions. The percentage of the result are: CU (17%), PP (4%), PM (39%), NU (13%), MC (27%), and NC (0%). This indicates that students' conceptions are still dominated by PM and MC categories. Students in the PM category have good characteristics but lack self-confidence. While the MC category is an unexpected result because students are confident in their answers that are wrong or not in accordance with scientific conceptions. Thus, further action is needed to overcome students' misconceptions.Keywords: Students' Conceptions, Fluid Pressure, Rasch Analysis
