  • The aim of the present study was to develop a cognitive-behavioral group therapy program for social anxiety in Korean adolescents and to examine its efficacy through pre-, post- and 2-year follow-up tests. The program included cognitive restructuring, exposure training and social skills training. KSAS-A and SASC-R were administered to 588 1st grade middle-school female students to assess their social anxiety levels. On the basis of double criteria procedure(top 10% scores on both scales), 59 students were selected initially. Individuals currently receiving clinical treatment were excluded. Finally, 40 students were selected and randomly assigned to either a treatment group or a wait-list control group. The program consisted of 12 weekly sessions, approximately 1.5-2 hours in duration. Whereas pre- and post-tests were administered to both groups, follow-up tests were administered to the treatment group only. The collected data were statistically analyzed through independent t-test and paired t-test. The results of the study were as follows: 1) At post-test students in the treatment group showed a very significant reduction in social anxiety and fear of negative evaluation by others in comparison with those in the wait-list group. 2) At post-test students in the treatment group showed a significant reduction in negative automatic thoughts in comparison with those in the wait-list group. 3) At post-test students in the treatment group showed a significant improvement in overall social skills in comparison with those in the wait-list group. 4) At post-test students in the wait-list group showed a significant increase in both social anxiety and negative automatic thoughts in comparison with those in the treatment group. 5) At 3-month, 1-year and 2-year follow-ups, the program's effectiveness was maintained.

  • Social media is an essential part of everyday life in modern society and plays an important role in communicating the ideal body image. With the increased prevalence and high popularity of social media, the problems associated with the addictive use of social media have become a social issue. Utilizing social comparison theory, this study examined (1) the effect of appearance related photo activities on body satisfaction through appearance comparison and (2) the moderating effect of Instagram addiction in relationships among appearance related photo activity, appearance comparison, and body satisfaction. We tested the proposed relationships between research variables using multi-group structural equation modeling analysis on a sample of 346 young female Instagram users. The sample was divided into two groups of high and low addicted Instagram users. The results of this study showed that the appearance related photo activity positively influenced appearance comparison for both high and low addiction groups. For the high addiction group, the effect of appearance comparison on body satisfaction was not statistically significant; however, this relationship was significant and negative for the low addiction group. A significant moderating effect of Instagram addiction was found in the relationship between appearance related photo activity and appearance comparison.

  • The purpose of this study is to find out how the reconstructed textbook for vocational high school students influences on students' scholastic achievement and affective domain when it is used in the class of vocational high school. To tackle the study problems, the researcher chose two classes of the first grade in G commercial high school and gave lessons to each of the two classes; one class, as an experimental group, was taught with the reconstructed textbook and the other, as a comparative group, was taught with the original textbook. The following results are derived from the study. First, it turned out in the post academic achievement test result, there is no significant difference between the experimental group and the comparison group, by significant level; .05. However, the prior academic achievement test result shows that the average of the comparison group is 0.44 points higher than the average of the experimental group, while the post test result shows that the average of the experimental group is 1.96 points higher than the average of the comparison group. Second, it turned out by the post affective domain test result, there is no significant difference between the experimental group and the comparison group, by significant level; .05, and any significant difference did not occur in all five areas. However, the whole point of the affective domain and the points of each area of experimental group are higher than those of the comparison group, and the degree of improvement in experimental group is also greater than that of the comparison group. In conclusion, the effectiveness of utilizing a reconstructed textbook in vocational high school math class can be expected in the long term.

  • The aim of this study is to clarify what influence has on elementary school children's environmental awareness in time of teaching environmental problems from an animistic viewpoint and from non-animistic viewpoint. For this purpose, this study carried out its research targeting 126 students in fourth grade at M elementary school located in U Metropolitan City. This study suggested the environmental problems by re-edifying the already suggested environmental problems from an animistic viewpoint to 62 students for two classes which were classified as an experimental group after sampling 10 cases of the representative environmental problems that might derive from the earth system, and conducted the class on 10 main topics relevant to the problematic situation of environment with an animistic viewpoint excluded targeting the remaining 64 students forming a comparison group. The results of this study were as follows: First, there appeared an ex-ante ex-post statistically significant difference in the awareness of environmental problems from the experimental group which received an environmental class from an animistic viewpoint. However, there didn't appear a statistically significant difference from the comparison group. This study interprets this result to mean that elementary students' awareness of environmental problems increase because they think about the environmental problems by associating them with a problem of life when the students receive the environmental class from an animistic viewpoint. Second, there appeared an ex-ante ex-post statistically significant difference in the awareness of environmental problems from the experimental group which received an environmental class from an animistic viewpoint. However, there didn't appear a statistically significant difference from the comparison group. Regarding this aspect, this study believes that the experimental group shows much higher willingness to environmental act in comparison with the comparison group because elementary school students think of inanimate objects as living things.

  • This study investigated the effects of cooperative learning environments in conceptual change instruction upon students' conception, achievement, learning motivation, attitude toward science instruction, and perception of involvement. Two classes of 8th graders at a co-ed middle school were assigned to the treatment and the comparison groups. They were taught about density, boiling point, freezing point, and solubility for 11 class hours. The treatment group's learning environment involved cooperative conceptual change instructions while the comparison group's environment incorporated individual conceptual change instructions. Mann-Whitney test results revealed that the scores of the conception and achievement test for the treatment group were significantly higher than those for the comparison group. The perceptions of involvement for the treatment group were more positive than those for the comparison group. The scores of the learning motivation test for the treatment group were found to be significantly higher than those for the comparison group based on a two-way ANCOVA analysis. However, attitudes toward science instruction were not found to be significantly different between the two groups.
