| Summary: | 碩士 === 國立臺南大學 === 教育學系科技發展與傳播碩士班 === 101 === The purpose of this study is to develop the “Collaborative Strategy (CS)” and apply it to the instruction of mathematical concepts of “Point, Line, and Circle.” Lesson activities included a series of collaborative works through manipulating interactive whiteboard (IWB) of geometrical graphics. The strategy highlighted a collaboration that each learner used what they learned to help others within a heterogeneous group. A quasi-experimental research was conducted to examine learners’ performance. Two classes of 9th graders (63 students) from a junior high school in southern Taiwan were included. One class (31 students) was assigned to CS group (experimental group). The other class (32 students) was assigned to non-CS group (control group). The researcher conducted performance tests, questionnaire survey, and interviews and analyzed the data in a triangulation approach. The study found that: (1) CS yielded a significant effect toward the learning in mathematical concepts of “Point, Line, and Circle.” (2) Learners preferred CS because they felt more confident in learning mathematics with peer assistance. (3) Most learners were interested in IWB. (4) Learners were more skillful in complementary learning through peer interaction. The findings implied that the integration of CS and IWB was helpful in learning mathematical concepts for junior high school students. This study also makes suggestions for educational practice and future research.
