| Summary: | 碩士 === 國立高雄師範大學 === 化學系 === 91 === The purpose of this study is to research into the effect of using computer-aided teaching material designed by the researcher as a method of promoting the learning of the concept of “air” for underachievers in Grade II.
With Case Study as approaching method, the research, based on the concept map formed by linking the limited words and the data concluded from the interviews, analyzes the variation of the subject student’s learning about the concept of air
The results concluding from analyzing the data are:
1)The percentage of the meaningful linkage number rises from the 34% of the pre-test to the 51% of the after-test; the percentage of the meaningless linkage number falls from the 64% of the pre-test to the 48% of the after-test, which proves that computer-aided learning material does have positive effect on the subject students’ acquisition of concept.
2)The structure of concept isn’t easy to form in the subject student’s brain, even through computer-aided learning. For “structure” is something abstract and not perceivable for the subject student. This makes the subject student unable to adjust, interiorize, and form the concept.
3)Computer-aided teaching material is proved to be helpful to form some of the abstract concept, such as liquefaction, the boiling point, etc. Meanwhile, after crosschecking the data of interviews before and after the test, the researcher finds that computer-aided learning also helps reinforce the concept already formed by the subject student.
