博士 === 國立臺灣師範大學 === 資訊教育學系 === 97 === This study proposed a hybrid lecture video plus lab approach for learning of image processing concepts in high schools. The effects of this learning model upon students’ performance and attitudes were investigated. Furthermore, the relationship between learners’ characteristics and before-class video viewing behaviour was also explored. A quasi-experimental research design was conducted at two high schools to examine the results. Six classes were randomly chosen for the experiment from each school. Of the six classes, two classes each were designated as experimental group 1, experimental group 2, and the control group. Students in the experimental group 1 (video+lab group) watched lecture videos before class and used the class time for lab exercises. Students in the experimental group 2 (lecture+lab group) received in-class lectures (the same content as in the lecture videos) and carried out lab exercises in class. The control group received the usual expanded lectures in class. The experimental results show that the proposed model is a feasible and effective way for the teaching and learning of image processing. The new approach also facilitates student-student and student-teacher interactions in the classroom. An improvement in the understanding of the subject by the students and an increased interest toward learning CS are also evident. Furthermore, students’ learning motivation is an important factor for before-class video viewing.
