Abstract
Before learning activities in class, some students have various conceptions, especially potential misconceptions. Therefore, this examination aims to develop Computer Simulation on Refutation Texts (CoSiReT) for wave learning. Updates on refutation text are useful to facilitate changing students^ conceptions regarding the basic concept of transverse waves. The 3D model (Define, Design, and Develop) is used for the precursory research design. CoSiReT is designed to integrate computer simulation on Refutation Texts and is developed in interactive form. The research instrument consisted of validation sheets for five experts and six practitioners (physics teachers) in Tuban, East Java, Indonesia. The instrument consists of 15 indicators covering aspects of 1) instructions for use, 2) language, 3) presentation content, and 4) appearance. Expert and practitioner judgment data analysis using a rater test assisted by Mini-Facet Rasch software. The results stated that CoSiReT fulfilled all aspects and there were improvements to several indicators by the validator. Accordingly, the precursor development of CoSiReT can be sampled and implemented as a learning innovation that seeks to change students^ conceptions of basic waves concept.
