The purpose of this study was to examine the effects of argument structure on students' writing in implementation of argument-based inquiry using the Science Writing Heuristic (SWH) approach. Participants of this study were 108 8th grade students (three classes). Two classes (68 students) were assigned to an experimental group, and the other class (35 students) was assigned to a comparative group. The experimental group was taught argument-based inquiry using the Science Writing Heuristic (SWH) approach, while the comparative group was taught with the traditional teaching strategy. After implementing this program, the two groups were asked to write summaries using structured argumentation in their writing. The result of this study showed that the experimental group used better argument structure and multimodal representation such as pictures, graphs and examples in evidence than the comparative group. The quality of evidence used in the students' writing was different between two groups. Students of the comparative group only listed fragments of science concepts for evidence to support their claims, but students of the experimental group explained science concepts by giving specific examples. The findings show that argument-based inquiry using the SWH approach was effective on argument structure in students' writing.

This study focuses on the 'invention technique and practical experience' unit to observe how the colleague mentoring class has its effect on self-efficacy. For this, we have selected experimental group and comparative group and proceeded the experiment. For five classroom hours of the 'technique of invention and practical experience' unit, each group was assigned different method to do the experiment. The experimental group was applied with the colleague mentoring method and the comparative group was applied with the self study method. To observe the differences of how it effects on one's self-efficacy, the questionnaire was distributed before and after class. Then, it was verified for the meaningful differences between the two groups. To summarize, the results are as follows. First, for self-efficacy experiment, the questionnaire before the experiment showed that there were no differences found between two groups. However, the questionnaire collected after the experiment showed great differences. The group with the colleague mentoring showed more meaningful differences at p<.05 significance level than comparative group. Furthermore, by observing the before and after questionnaire, it was found that both groups showed statistically meaningful differences at p<.05 significance level, but the experimental group showed greater self-efficacy improvements than comparative group. Second, when further examining the self-efficacy, the activity start expectation, activity continuation expectation, activity performance expectation, and experience recovery expectation showed the statistically meaningful differences at p<.05 significance level. According to the above results, it can be stated that the colleague mentoring class has more positive effects on the self-efficacy than self-study class. Summing up, the colleague mentoring class is more effective than self-study for fostering student's self-efficacy.

This study investigated the effects of social presence as means of self-awareness and interpersonal-awareness on the cyber-aggressive behavior. The cyber-aggressive behavior (flaming and direct aggression use of character) should be differ from existence of social presence and type of social presence of internet users. To test hypothesis, an experiment was executed a field study on cyberspace, an on-line game, "fortress 2 blue forever". I made a chat-room in the game site to conduct an experiment to 107 person who entered the chat-room and blinded ignorance of this situation made by researchers. As the subjects enter the chat-room, he chats with 3 researchers who were waiting before he gets in. The social presence was operated with 3 phases by the contents of the chat (①control group; nothing, ②experimental group 1; reaction about other people ③experimental group 2; reaction about other people + self-exposure by an exchange information of their home region). The studies show that, subjects of the control group behaved more aggressively than other subjects of the experimental groups(both flaming and direct aggression use of character). Meantime, I compared experimental group 1 with experimental group 2 to investigate difference between the type of social presence. As the result, subjects of the experimental group 1 behaved more aggressively than experimental group 2 (only flaming, there's no difference in direct aggression use of character).

Experiments were performed on three subsets of a Korean test collection in order to determine whether 2-Poisson model's Z value is a good measure for selecting subject words from a document to be indexed. It was found that subject word selection based on the Z value was effective for only one subset with short texts, i.e., the Science and Technology subset. Correlation analyses between 2-Poisson model's Z and TF.IDF weight for the three subsets showed that the correlation was relatively high for two test subsets with short texts, i.e., the Science and Technology subset and the Newspaper subset.
