Web-Based Teaching Materials Design Using Theory of Didactical Situation Approach

Abstract
Abstract - In the era of society 5.0, humans live side by side with technology because technology can facilitate various human affairs, one of which is in the education sector. This study aims to describe website management as a student learning media which is a form of technology utilization in education sector. The method used in making teaching materials is Development Research which consists of three stages. However, in this paper, the research is only focused on the initial investigation and prototyping stages. This teaching material is designed into three parts, namely the material section, experiment gallery and cognitive evaluation. In the material section, the delivery of concepts is arranged based on the stages of TDS so that interactive students carry out their cognitive processes through the stages of action, formulation, validation, and institutionalisation. Based on the validation carried out that web-based teaching materials using the TDS approach are suitable for use. Keywords - Teaching Materials, Technology, TDS, Website
