How to Develop Colligative Properties of Solution Chemistry E-Book Based Science Process Skills Approach With 4S TMD Models ?
The study aims to develop colligative properties of solution chemistry ebook based science process skills (SPS) approach with 4S TMD. Today, school facilities have supported the implementation of digital-based learning. However, teaching materials are digital based, one of which is that the e-book is not yet available in the learning process. Then, teaching materials available are less associated with phenomena, less emphasis on the learning process. It is expected that teaching materials can facilitate students to experience meaningful learning especially in the material of colligative properties of solutions. Meaningful learning processes can be supported by a process-based approach that allows students to learn scientific phenomena with insight and understanding through SPS. Then we need teaching materials that contain content that can develop SPS. Development Research (DR) was used as method of the study by Richey and Klein that consists of design, development, and evaluation. The design step is analyzing and designing the types of developed teaching materials. 4S TMD models consists of selection, structuring, characterization, and didactic reduction. There are 2 basic competencies that exist in the curriculum based on the selection steps, the interrelationships between subject matter and indicators, the relationship between certain skills and subject matter. The structuring step produced concept maps, macro structures, and many representations were compiled to become the first concepts of teaching materials used to develop instruments for the characterization step. This research only to structuring step, characterization and didactic reduction steps will be carried out.Introduction.
