Özet:

In this study, 30 hours of training were given to 15 science teachers to realize STEM integration in science courses and it was aimed to examine the problem statement developed by science teachers who have STEM education. The model of the research is a holistic case study. The study group of the research is composed of 15 science teachers. Problem statements (documents) that the teachers developed constitute the primary data source of this research. Field notes were used as supporting data sources. Data analyzed by descriptive (documents, field notes) and content analysis (field notes) techniques. It has been determined that the engineering design problem, prepared by only one teacher, can be accepted in all elements, and that it is capable of integrating mathematics and technology disciplines and achieving learning outcome in science courses. It has been found that none of the problem statements prepared by problem-based learning to perform STEM-focused activities in science courses are inappropriate for all elements.
