The development of a simple solar energy heater as a stem based instructional material for high school students

Abstract

This preliminary research aims to design instructional material for high school students. The research method used in this development is ADDIE (Analysis, Design, Development, Implementation, and Evaluation). The developed Instructional Material refers to the NGSS (Next Generation Science Standards)'s first dimension. Our design and development stage includes five parts, namely designing and building the equipment, applying the equipment to measure some physical quantities, data analysis, the effectiveness of teaching and learning, and developing lesson plan for teaching and learning. The result of the development is a comprehensive Simple Solar Energy STEM project lesson plan. This project could discuss various integrated topics, processes, or phenomena such as fusion process in a star, greenhouse effects, electromagnetic waves, alternative energy, thermal physics, and lenses which can be depicted in a concept map. The core competencies, time allocation, assessment, and concept map are incorporated into the lesson plan as part of the instructional material. The designed STEM heater project has discrepancies of 16% and 6.8% compared to advanced tools. These discrepancies are tolerable for educational purposes. The STEM Project is also applicable in every school as it is simple and the material is easy to find.
