The aim of this study is to develop a suicide prevention course that includes technology, career, STEM (Science, Technology, Engineering, and Mathematics), and play education (TCSP). The study also aims to explore the effects of the TCSP course on college students' knowledge, confidence, and readiness. The research methods include action research and a quasi-experimental study. The subjects comprise college students, with 54 in the intervention group and 36 in the control group. The instruments used are a scale measuring suicidal knowledge, confidence, and readiness, as well as a feedback sheet for the course. Data are analyzed using descriptive analysis, analysis of covariance, and content analysis. The results indicate that the scores in the intervention group were significantly higher than those in the control group in terms of knowledge, confidence, and readiness to face suicidal cases through the TCSP course. Students recognized the teaching material and teaching process affirmatively, and they felt that their professional ability to manage suicide cases had increased. These results demonstrate that students' knowledge of suicide prevention increased, and they had positive experiences with TCSP.
