Abstract
Innovation behavior (INB) is considered a particularly significant outcome in every level of education management, professional work, and across various organizations. There is still a lack of clear understanding regarding the suitable approaches and formats for fostering INB among undergraduate students. This research presents the results of the Integrated Thinking Promotion Program (ITPP) as an extra-curricular activity which effectively promotes undergraduate students' INB. Quasi-experimental research was conducted involving 68 university students in Thailand, the experimental group received the ITTP program for three weeks, while the control group received regular course instruction. INB scales were used to collect INB with both groups. The study found that the ITTP program significantly promotes undergraduate students' INB. This finding provides challenging directions for higher education management, emphasizing the implementation of short-term extra- curricular activity to foster the development of INB among undergraduate students.
