The development of learning tools to enhance mathematical problem-solving ability through ICT-assisted preprospec learning model

Learning tools such as syllabus, lesson plans, teaching material as superior product, student activity sheets, and GeoGebra learning media through the ICT-assisted Preprospec learning model are innovations in mathematics teaching and learning to improve students’ ability to solve mathematical problem. This research applied Research and Development (R&D) method with 4D models. It had three steps, namely define, design, and develop. The results showed that all learning instruments covering a syllabus, lesson plans, teaching material, student worksheets, and GeoGebra learning media on polyhedron material were very suitable to be used in learning activities with the feasibility percentages of 95.37%;94.70%;91.77%;92.71%; and 94.79%. In terms of readability, after the teaching material was tested using Cochran Test, it gained value Q=13,67
