Applying the Delphi Method to Develop a Competency Framework for Problem-Solving and Creativity in High School Students

Problem-solving and creativity competence is one of the three core general competencies that must be formed and developed in high school students under the current General Education Curriculum in Vietnam. However, the integrated approach to this competence remains limited, particularly in the context of chemistry teaching. Building on both domestic and international research, our team developed a structural framework for high school students’ problem-solving and creativity competence consisting of six components and ten assessment criteria. To verify its scientific validity and feasibility, the Delphi method was applied through two rounds of consultation with 20 experts and one pilot testing round. Data were analyzed using SPSS software based on the KAMET procedure, employing the Mdqi, Qqi, Mqi, and Vqi indices. The results indicate that all criteria reached a high level of consensus, with Mqi values ranging from 3.95 to 4.20 and Vqi below 10%, confirming the relevance and strong applicability of the proposed competence framework.
