Abstract
Abstract. Creative thinking skills are very important in the 21st era. The 21st-century skills require a person to have 4C skills (Critical Thinking, Communication, Creative Thinking, and Collaboration) where creative thinking skill is part of 4C. This skill does not rise automatically, we need to prepare systematically especially on the academic side, such as in the university. The creative thinking skills can be integrated into the teaching and learning process by implementing a specific model, namely research-based learning (RBL). By this model, students are involved actively to determine a solution for a complex problem. The problem giving a potentially complex problem is the problem arising from social real-life problems. Therefore, we need to elaborate STEM approach, i.e. Science, Technology, Engineering, and Mathematics together with the RBL model. In this study, we will focus on the preservation process of food or meat, since the biggest problem of some preservatives contains harmful substances, like formalin and borax. By combining the model and the approach, we will develop research-based learning materials with a STEM approach to improve the student^s creative thinking skills in using chitosan as a breakthrough for the preservative of processed meat. This study using the Research and Development (R&D) method with a 4D development model consists of four stages, namely Define, Design, Develop, and Disseminate. The learning material products are the lesson plan, students^ worksheets, and assessment instruments. Data collection instruments for testing validity, practicality, and effectiveness are questionnaires, observation sheets, and feasibility validation sheets (content, format, and language). The results show that the learning materials satisfy content validity, format validity, and language validity. The result of practicality and effectivity tests shows a significant contribution to the improvement of student^s creative thinking skills.
