(2) Integrating Mathematic Writing into an On-line Discussion System and a Study of its Effect on Junior High Students’ Mathematic Learning Student：Chieh-Min Tseng. Advisor：Dr. Fwu-Shyang Chen Dr. Yuan Yuan. College of Science Degree Program of E-Learning National Chiao Tung University. ABSTRACT A quasi-experimental design was used to study the effect of integrating mathematic writing into an on-line discussion system on junior high students’ mathematics achievement and attitude toward mathematics. Sixty-two first graders from two different classes of a junior high school in Taipei County served as subjects. Both of the two classes were taught by the same mathematic teacher. One received the experimental treatment and the other served as the control group. An achievement test and an attitude questionnaire were designed to measure students’ mathematic achievement and attitude. Finally, students’ writing works were analyzed and discussed. Research results showed that, students in the experimental group performed better in the achievement test than those in the control group. However, no significant difference of mathematic attitude was found between the two groups after the treatment. Findings from analyzing students’ writing works were as following. 1. Students are more willing to express their learning difficulties and opinions in an on-line discussion environment than in a traditional classroom. 2. Students show an incapability of evaluating other students’ writing works. 3. Students are not familiar with typing mathematical symbols to communicate when they need to express their ideas in an on-line discussion system. 4. Students like to use phonetic notations or expression marks to express their ideas. 5. Students write a lot of wrong words and incomplete sentences. 6. Students often give text-like examples to explain a concept and show a lack of ability to translate between different representations. Based on the research results, some suggestions are proposed for future studies.. Key Words: mathematical writing, on-line discussion system, junior high students. ii.
