Developing Conceptual Change Text on the States of Matter and Their Changes for Prospective Elementary School Teachers

This research aims to develop a Conceptual Change Text (CCT) for prospective elementary school teachers’ understanding of states of matter and their changes through text to fulfill valid, practical, and effective criteria about the Basic Concepts of Science, henceforth TPK-MP (Teks Perubahan Konseptual Materi dan Perubahannya). This research employs research and development of the 4D model: define, design, develop, and disseminate. The instruments included observation, questionnaire, interview guidelines, validation papers, and concept mastery test. The data obtained were analyzed according to validation, practicality, and effectiveness criteria. The results showed that conceptual change text on states of matter and their changes and CCT developed was valid with an average score of 95.32 (very valid), practical at the score of 3.56 (good), with the students’ positive response at 86.74%; and effective in which the conceptual changes were at 57.40% (medium). TPK-MP can improve understanding of concepts and reduce misconceptions about the matter and its changes. It can be used to develop conceptual change text for other science materials. Further research is needed to determine the effectiveness of lectures using TPK-MP as an independent study material.
