The 2009 Revised National Curriculum introduces plans for the "intensive course completion system". This study investigated students' learning satisfaction with and perceptions of Life Science in the humanities and social science course in general high schools according to the implementation of the intensive course completion system in the 2009 Revised National Curriculum, and analyze relations with gender and with academic achievement levels. The findings are as follows: First, the students in the humanities and social science course recorded an overall low learning satisfaction in Life Science through the intensive course completion system. It was analyzed that they especially found it burdensome to take the lessons four hours per week in one semester according to the system. Second, the students in the humanities and social science course didn't have positive perceptions of a need to study Life Science when considering their future career choices, but they positively perceived when considering its educational benefits. Third, the more learning satisfaction with Life Science they had according to the intensive course completion system, the higher learning perceptions they had. Finally, the girls showed a higher level of learning satisfaction and perception than the boys. The higher their academic achievement was, the higher their learning satisfaction and perception level became.

The purpose of this study is to explore high school students' perception of the relationship among science, history, and history of science which is one of the career elective subjects in the 2015 revised science curriculum. This study compares students' perception before and after experiencing history of science course. To do this, data in the format of Venn diagram that students draw to represent their perception on relationship between the history of science, science, and history were collected. The collected data were inductively categorized. As a result of analyzing the Venn Diagram data, there are five different kinds of categories: 'History of science as an intersection of science and history,' 'History of science as an independent domain,' 'History of science as part of history,' 'History of science as part of science,' and 'History of science encompassing both science and history.' And there were 27 different sub-categories within the 5 categories. In addition, before taking the course on history of science, many students tended to regard science history as the intersection of science and history. However, after the course, students' perception changed and differed according to their affiliated academic track. For the humanities, history of science is perceived as part of history, and for the students in science track it is perceived as a part of science. Based on these findings, we suggest that history of science teaching-learning should be conducted that help high school students to experience a new perspective that is different from the curriculum in affiliated academic track.

Despite the close relatedness of the factors for reading motivation and book selection, few researchers have examined these factors together in a single study. To deal with this dearth of research, this study was designed to explore factors of motivation for reading and book selection of high school students comprehensively. The authors conducted in-depth interviews with fifteen high school students and analyzed their responses in order to identify the meaningful factors. The findings of this study reveal the five major factors: (1) characteristics of information sources, (2) school and learning environment, (3) individual factors, (4) home environment, and (5) social environment. In particular, the five types of factors seem to have a combined effects on reading motivation and book selection. The findings also suggest that one's reading motivation is a prerequisite for his/her book selection; however, the reading motivation does not always lead to book selection. The results of this study may deepen our understanding of reading behavior of high school students, which can be used in reading instruction and designing new programs.

The present research is aimed to observe the effects on the peer counseling program which can increase the communication skills and social efficacy of high school students. In order to do the present research, I have taken 16 high school students, who want to join to this research, within A city. I have separated those students into two groups: an experienced group of 8 students and a controlled group of 8 students. Mann-Whitney U and Wilcoxon Signed Ranks test were adopted to analyze collected data from the peer counseling program. The results of this research indicated that the level of communication skills have been increased after peer counseling intervention program of the experienced group, and the level of occupational stress also have been increased after peer counseling intervention program of the experienced group. This result showed that, the peer counseling program could stimulate the communication skills and social efficacy of experienced group significantly comparing with the result of the controlled group. From the result I have confirmed that, the peer counseling program have positive effects to increase the high school students' communication skills and social efficacy.

The study examined the influence of socially-prescribed perfectionism (SPP) on depression and social anxiety, and further investigated the mediating effects of self-focused attention and self-criticism. The questionnaires designed to measure multidimensional perfectionism, social anxiety, depression, self-focused attention, self-criticism scale for adolescents were administered twice at an interval of three weeks to 273 students (83 men, 190 women) enrolled at high schools in Gyeonggi-do Province. The findings for the present study were as follows. First, SPP, depression, social anxiety, self-focused attention, and self-criticism showed all positive correlations. Second, the mediation effect from the SPP to depression via self-focused attention was statistically significant, whereas the indirect effect from the SPP to depression via self-criticism was not. Third, the pattern in depression was the same in social anxiety. The results provide indirect support for the social anxiety cognitive model (Clark & Wells) with regards to social anxiety particularly in Korean high school students. Finally, the implications and limitations of this study and suggestions for future research were discussed.

This study investigated high school students' perception of English extensive reading (ER) after introducing ER to general high school students in a metropolitan area. In addition, as the free semester system was expanded in high schools as well as middle schools, we developed a class model for English extensive reading. 91.4 percent of the students who participated in the study said that they wanted to try using the English extensive reading method. Also 35 high school students who experienced English extensive reading chose the 'Five Finger rule' and 'Graded Readers' Series' as the most helpful factors in their extensive reading experiences. In interviews with English teachers, teachers expressed their demand for the development of a model of English extensive reading suitable for free semesters in general high schools. This study proposes an English extensive reading class model utilizing library resources that can be used in the free semester system as well as a performance assessment-oriented English extensive reading class model.

This study aims to investigate the motivation for science learning of 3rd year high school students who choose different majors from their track. A total of 2,012 high school 3rd year students participated in this study. We used Science Motivation Questionnaire II (Glynn et al., 2011) to measure the students' science motivation and performed Rasch analysis, MANOVA and logistic regression analysis. First, results showed that 11.5% of students in the science track switched their pathway to a non-STEM major and 14.3% of students in the humanities track switched to a STEM major. In addition, there were gender differences in switching majors. Second, we found a significant difference in science motivation between two groups of students switching their major only in career motivation. Third, science motivation was the significant predictor of STEM major choice; in particular, career motivation was the most influential variable. Based on these results, we proposed that prediction of and paying close attention to students' career motivation are required before making decisions on which track to take.
