The tragic series of students' suicide in KAIST, one of the leading STEM universities in
Korea, concerned the Korean society immensely, and raised questions about the effectiveness of its
educational policies and programs. In order to address the fundamental issues, however, the whole
campus environments should be carefully and in-depth examined. Ecological approach views
campus as composed of various environmental factors and their interactions. Cultures of numerous
dimensions detected in campus is one of the critical environmental factors exerting huge influence
on students' attitude and behaviors. This study focuses on finding out unique characteristics of
the campus culture in a Korean STEM(Science, technology, engineering, and mathematics)
university. Four interconnected themes have emerged, and the interactions of campus
environmental factors contributing to the creation of the campus culture were examined from the
ecological perspective. Practical implications for improving campus environments of STEM
universities were discussed.
