Developing Problem-Solving Competence for Primary School Students through Science Teaching Based on OTSM–TRIZ Theory

This paper focuses on studying the theoretical foundations and assessing the feasibility of applying the OTSM–TRIZ theory to develop problem-solving competence for primary school students through Science teaching. Based on a review of relevant literature, the study clarifies the nature of the OTSM–TRIZ theory, the role of problem-solving competence in the 2018 General Education Curriculum, and the potential for integrating OTSM–TRIZ principles into primary school Science instruction. To evaluate its practical feasibility, the research team conducted a survey with 139 primary school teachers using a five-point Likert scale. The results show that most teachers highly appreciate the relevance and potential effectiveness of OTSM–TRIZ, while also noting some challenges related to professional expertise and implementation conditions. From these findings, the paper proposes directions to support the application of this theory in educational practice.
