| Summary: | 碩士 === 國立臺中教育大學 === 語文教育學系碩博士班 === 98 === The purpose of the study was to see the applicability and effects of BNAT in the fifth & sixth graders of the elementary school, so to design the language teaching materials based on knowledge structure and set them into the computerized adaptive test, to test on-line for knowing the effects of the remedial instruction with individual multimedia materials, to reach the effects of teaching students in accordance with their aptitude and test through the analysis of the relationships of learning styles and adaptive test.
The study adopted the self-designed language materials. Ten senior’s classes were selected from three central counties. The materials were based on the knowledge structure, of which to infer the fault styles, to propose testing systems. It formed Bayesian Networks. First, there was the clinical evaluation of a class with the materials, then the formal evaluation of nine classes. We could get the students’ knowledge structure from the OT(ordering theory)map drawn according to the test responses, even produce the remedial teaching structure in comparison with the knowledge structure and the remedial materials. On the inference and analysis of OT, we could set the computerized diagnosis adaptive test. Students of two classes went on the remedial teaching with the test report.
The results were as the followings:
1. The scholars and teachers affirmed and identified the self-
designed language materials
based on the knowledge structure..
2. The knowledge structure could help researchers to design the
language materials
because the knowledge structure is whole and systematic.
3. The knowledge structure could construct the language computerized
adaptive test effectively.
4. The remedial teaching results showed that the remedial materials
can enhance the teaching effects.
5. The analysis of the learning styles helped students to learn the
language material adaptively.
Based on the results, this study provided suggestions for designing the language materials based on the knowledge structure and application of the computerized adaptive test , and future research.
