Aiming at the problem of the compatibility disequilibrium of traditional play-teaching AIDS in the dual perspectives of "play" and "learning", the work aims to develop a set of disciplinary play-teaching AIDS product design methods by combining the constructivism education theory and the analytic hierarchy process so that it can serve the research and development design of disciplinary play-teaching AIDS products. Firstly, through the analysis of the constructivism education theory, the elements of learning environment were summarized as stimulating difference, active activity, cooperative communication and constructive evaluation. Secondly, the elements of learning environment were mapped to user needs, and the key elements affecting the design of disciplinary play-teaching AIDS were screened using the analytic hierarchy process. Then, taking the elementary school language writing as the case study, the key elements for the design of disciplinary play-teaching AIDS were combined with children's characteristics and subject content to establish the design orientation of disciplinary play-teaching AIDS and produce a plan. Finally, the constructivist theory was combined with user needs to establish evaluation indicators and evaluate the plan. With the constructivism as the framework and the analytic hierarchy process as the tool, the design method of disciplinary play-teaching AIDS is superior to the traditional disciplinary educational products in terms of education, interest, participation and cooperation. The results show that the product design method based on the constructivism and the analytic hierarchy process is feasible, and can provide a set of qualitative and quantitative design methods and new research ideas for the innovative design of disciplinary play-teaching AIDS.
