| Summary: | 碩士 === 國立臺灣師範大學 === 科技應用與人力資源發展學系 === 104 === This research aimed to discuss the effects of STEM-based hands-on activity with 6E Learning by DesignTM Model in developing junior high school students’ attitudes toward technology, ability of technology inquiry and ability of theory-based design; under the conduct of nonequivalent quasi-experimental research, and 212 junior high subjects participated the assigned groups over ten courses of ten weeks. Respectively, applied the 6E Learning by DesignTM Model and Problem Solving methods to the assigned groups by means of “technology attitude scale,” “technology inquiry scale,” “students’ portfolios,” “participant interview,” “questionnaire,” and “teaching introspection”. The STEM practical activity is “Mousetrap Car and Launching.” The quantitative data adopted one way ANCOVA, and the qualitative data was analyzed accordingly. The main findings feature: (1) The “Explore” step may mutually enhance and establish technology attitude and specific conception of theory; thus students could design upon the theories. (2) The “Engage” step shall apply students’ actual habits as the theme. (3) The “Explore” and “Explain” steps may improve students’ ability of technology inquiry by data collecting, analyzing and inquiring.
