The purpose of this study is to investigate the effects of intervention on technology literacy of design-major students in the college of design in terms of their recognition, perception, attitudes, self-efficacy, and behavioral intention of technology literacy. We purposely sampled 42 first-year volunteer students from the department of product design (19 for the experiment group and 23 for the control group). Session activities of 12 hours lasting for four days (on technology and life, energy and transportation, construction and manufacturing, and opinions sharing and feedback) were conducted. Instructional methodologies included direct lecturing, group discussion, game competition, video viewing, and drawing. Both groups were pre-tested before the intervention. The experiment group was post-tested and was asked to fill out the unit activity feedback sheet while the control group was only post-tested. Data collected were analyzed by percentage, Mann-Whitney U-test and step regression analysis. The analysis indicated the following findings: 1. Students from the experiment group performed better in the concepts of technology literacy than those from the control group. 2. Students from the experiment group improved significantly on their scores of "awareness of technology literacy", "attitude toward technology literacy", "perception of technology literacy", "self-efficacy of technology literacy", and "behavioral intention of technology literacy" in the measurement compared to that of before the intervention. 3. Students participated in the intervention reported satisfaction on all the four teaching units both in content ad methodologies. They regarded the intervention course as enjoyable and helpful. They also highly evaluated the overall activity; the curriculum structure and instructor himself were both highly recognized.
