| Summary: | 碩士 === 國立臺灣師範大學 === 生命科學系在職進修碩士班 === 98 === The study is to compare and contrast the influences on the learning motivation and performances of the seventh graders about Circulation System by integrating Powerpoint multimedia and the conventional instruction. The study adopted a quasi-experimental design. The subjects were from two seventh-grade classes in a public junior high school in Taoyuan County. The Powerpoint multimedia was developed following the Dual Code Theory and applied in the experimental group (N=33). Lecture complemented with posters was applied in the conventional instruction group (N=34).
Students’ scores from the Circulation System Performance Test (CSPT) and the Science Learning Motivation Questionnaire (SLMQ), and transcripts of semi-structured interview were collected. The t-test, ANCOVA, ANOVA, and MANOVA were conducted to analyze the quantitative data to exam the relationship between different variables. The interview transcripts were used to cross-check with quantitative results.The findings of the study are as follows:
1. There are significant differences on the pre-test, post-test, and retention test of the CSPT between the experiment group and control group.
2. The learning effectiveness of the experiment group is significantly better than the control group.
3. By integrating Powerpoint multimedia into instruction, students’ understanding learning effectiveness can be promoted.
4. There are no significant differences on the retention test results of the experiment group and control group.
5. The results of the SLMQ of the experiment group are better than the ones of the control group. Thus, it shows that by integrating Powerpoint multimedia into instruction, students’ learning motivation can be promoted.
