Development of Teaching Aids- Interactive Inventive Principle Drawers for Form 2 RBT Subjects

Abstract

Design and Technology (RBT) for Form 2 introduced the subject of Inventive Principles, which encompassed 14 proposed inventive principles under two primary methods: the spatial separation method and the temporal separation method. The Theory of Inventive Problem Solving (TRIZ) is a methodology that is designed to enhance the efficiency of problem-solving by implementing these innovative principles. Nevertheless, the absence of tangible materials to elucidate the practical application of TRIZ principles in the classroom creates challenges. Consequently, the project’s objective is to create an interactive inventive principle drawer as a teaching aid for the Form 2 Design and Technology subject. From the viewpoint of experts, the primary objective of this investigation is to develop and assess the efficacy of the Teaching Aid for Inventive Principles. The specific objectives are to determine the necessity of the teaching aid, develop it, and evaluate its usability from the perspective of experts. The ADDIE model is adhered to in the study design. This investigation employs a qualitative methodology, with semi-structured interviews that prioritize purposeful sampling strategies and concentrate on individuals who have been instructed on inventive principles. The usability of the developed teaching aid was assessed through interviews with three expert informants: Two secondary school teachers and one lecturer from a public university. The interviews with the expert informants yielded the following results: the teaching aid developed satisfies the specified objectives, and the experts concur that it is appropriate for use as a teaching aid during teaching and learning sessions. Interview sessions with experts were conducted to solicit suggestions and enhancements to improve the quality and added value of the teaching aid in the future.
