The story-based curriculum in Engineering Science Classroom (ESC) is a new methodology of integrated STEM and engineering education in Thailand, which was first introduced nine years ago. However, there is no strong evidence to support an effectiveness of the pilot program. In this study, we present descriptive and analytical results of the achievement of the program including the number of

The findings suggest that the students performed very well in classrooms with high correlations among Grade Point Averages (GPAs) of STEM subjects, and the number of students who attended engineering majors in colleges was greater than other majors. Moreover, results from a multinomial logistic regression reveal that there were significant effects of choosing the other majors over engineering when using Science and Project scores as predictors. In sum, the successfully integrated curriculum is well established in this study.
