The innovative education trend is gradually developed on/off campus in past years. The constant integration of digital technology with education generating the new-style education model redefines the integrated activity and information technology curricula at schools. Creative thinking aims to cultivate students combining various situations (e.g., scientific situation, industrial situation, living situation) with creative design and developing original research and problem solving with specific engineering goals.
Taking college students in Bangkok, Thailand, as the research object, total 316 students are preceded the 16-week (3 hours per week for total 48 hours) STEM inquiry method experimental research. The research results are summarized as below. 1. STEM inquiry method cultivates students’ personal scientific activity and inquiry ability without restricting the ideas, but guides students to experience the complete learning process. 2. STEM education, with integrated instruction, cultivates students learning knowledge and skills for the application to real life. During students’ learning, the integration of subject knowledge, life experience, and learner-centered is emphasized. 3. Taking the curriculum design principle of STEM inquiry method, i.e. students’ interested issues, into the consideration of curriculum design and combining several relevant curriculum fields for integrated instruction, the planned self-directed learning activities and opportunities could assist students in applying the learned knowledge to solve problems in real life so as to enhance students’ creative thinking ability. According to the results to propose suggestions, it is expected to help students learn complete knowledge and, more importantly, present critical thinking and problem solving abilities.
