In this age of the $4^{th}$ industrial revolution, we, science educators, are giving more light on students' agentic behavior in the process of educating future scientist. This study, with the analytic lens of epistemic agency, explores the key stages of a student-driven R&E program rather than the scientist-led R&E program. It also examines to understand the emergence of students' epistemic agency in each stage of R&E. Data from participant observation for 18 months and in-depth interviews were collected and analyzed with the constant comparative method of grounded theory. This study identifies and describes five key stages of student-driven R&E: The stage of exploring research theme, designing research, performing lab activity, interpreting results, and communicating research. It also finds that (a) students' epistemic agency emerged with the constant interactions with the R&E structure; (b) students' epistemic agency has deep relations with the epistemic beliefs of the students; (c) students positioned themselves as decision-makers in the R&E practice; (d) the redistributed power and authority of the R&E contributed to the emergence of students' epistemic agency.

The purpose of this study is to categorize learning style groups and to analyze students' learning interest and self-regulated learning abilities, according to their learning style and giftedness. One hundred and twenty-three (123) science-gifted student and 296 regular students participated in this study, responding to learning style, self-regulated learning, and learning interest questionnaires. Data were analyzed, using 2-stage cluster analysis, $x^2$ test, two way-MANOVA test, and $Scheff{\acute{e}}$ test. The results are as follows: First, by 2-stage cluster analysis, four groups were categorized: 'high-score thinking style,' 'external-liberal,' 'executive-conservative,' and 'low-score thinking style.' In the gifted group, high-score thinking style (51.2%) was the most popular, then executive-conservative (30.2%), external-liberal (17.1%), and low-score thinking style (1.6%); in the regular student group, the executive-conservative group was the biggest, then high-score thinking style (20.6%), external-liberal (11.6%), and then the low-score thinking style (8.7%). Second, in terms of learning interest, the analysis by thinking style showed that the high-score thinking style group had higher learning interest compared to the executive-conservative and the low-thinking style group. The high-thinking style group's thoughtful interest also scored the highest compared with the others. The gifted students' thoughtful interest and investigative interest also were higher than regular students '. Third, in terms of the self-regulated learning, the analysis by thinking style showed that the high-score thinking style group showed higher scores on all sub-variances than other groups, especially having highest control-belief scores. Also, gifted students had higher scores on control-belief and searching information. Based on these results, the ways for effective education and support were discussed.

This study was undertaken to explain weight control behavior and intention of obese children and adolescents as measured by the elements of the health belief model. A total of 732 obese students from 28 schools in Seoul metropolitan area and their mothers were assessed with a self-administered questionnaire. The analyzed results are as follows; 1. Among obese students, 45.3% of male students and 57.2% of female students, a significantly higher portion than male students, reported that they had tried to lose weight within the recent year. Exercise was the most frequently used method to lose weight followed by diet control, drug use, and specialized clinic visits, in descending order. 2. Male students were more likely to try to lose weight if they perceived a low threat level and their mother had a job, and female students were more likely to try to lose weight if they were younger in age, perceived a low threat level and had strong external motivating factors. 3. Female students showed a significantly higher level of intention to obesity control than male students, and the intention level of their mothers also showed the same trend. 4. In male students, the degree of weight dissatisfaction, weight control experience, the level of obesity related beliefs of students, the educational level of the mother and economic status of the family were significant predictors of intention to obesity control, and in females, age, the level of obesity related beliefs of students and intention of their mothers were significant. In the mothers of male students, obesity index of students, age of the mother and the level of obesity related beliefs of the mother were significant predictors of intention of the mother, and in the mothers of female students, obesity index of students, occupational status of the mother and obesity related beliefs of the mother were significant. 5. According to the path model of intention to obesity control, the degree of weight dissatisfaction had the most powerful effect in male students, and perceived net benefit level was the most important variable in female students. Since the weight control behavior and intention of obese students were more predictable by the degree of weight dissatisfaction than the obesity index, we can conclude that only the students dissatisfied with their weight are well motivated for obesity control. There can be a discrepancy between the mother and her child's beliefs and intention status(especially in male students), so the therapists should also assess the student's opinion as well as the mother's. In female students, the perceived net benefit level wag the most important predictor of intention to obesity control, therefore the intervention program should pay particular attention to the positive benefits of weight control rather than negative aspects(threats) of obesity.

An assessment instrument dealing with secondary students' views on the nature of science was developed in this study. The features in aspects of the nature of science are generally accepted as characterizing the scientific enterprise and we have focused on are: 1) the purposes of the scientific enterprise, 2) the nature of scientific enquiry, 3) the nature and status of scientific knowledge, and 4) the nature and functioning of the scientific community. The questionnaire is made of three sections; that is, "Scientific Question", "Experiment", and "Belief". The Scientific Questions probe was designed to examine the ways in which learners mark out science as a particular domain, and particularly the types of questions that they think are open to scientific investigation. The Experiment probe was designed to throw light on the ways in which learners may think about theories and their relationship to evidence in a range of contexts. A related aim concerns the sorts of activities that learners consider to be experiments, and their reasons for this. The Belief probe was designed to see whether students are able to articulate the grounds for their acceptance of a proposition and, if they are, to explore the nature of these grounds. The reliability of the instrument developed in this study was found to be 0.86.

The purpose of this study is to investigate the seven-hour sexuality education program for senior high school girl students and apply it to them to find out how this program affects their sex-related knowledge, sexual attitudes, and the self-efficacy of sexual behavior practice. The ultimate goal of this study is that high school girl students are to prevent unwanted pregnancy, STD and AIDS, after attending this sexuality education program. A non-equivalent control group pretest-post test design was used for this study. The number of experimental group consisted of 80 girl students and the control group was composed of 80 girls, too. A total of 160 freshmen from two commercial girls' high schools were selected by a convenience sampling method. This study was carried out in commercial high schools located in Daejeon, Korea from July 15th to October 31st, 2002. To discover the need for sexuality education, the researcher surveyed with a pre-designed questionnaire to 160 girls from the two different commercial high schools. The sex education curriculum was developed on the basis of the need of high school girl students for sex education survey results and literature review and a teaching-learning planning model and health belief model. The experimental group was taught the sexuality education program for seven hours from October 19th to 23rd, 2002 and each period continued for 50 minutes. The SPSS(10.0) Windows statistics software was used to analyze the data, along with frequency, percentage, $X^2$-test, t-test, and paired t-test. The instruments' internal consistencies were tested by Cronbach's alpha coefficient. The results of this study were as follows: 1. The increment of sex-related knowledge score after seven hour sexuality education was significantly higher in experimental group (t=-10.88, p=.000). 2. The increment of sex-related attitude score after seven hour sexuality education was significantly higher in experimental group (t=-2.67, p=.009). 3. The increment of the practice of self-efficacy of sexual behavior score after seven hour sexuality education was significantly higher in experimental group(t=-4.95, p=.000). In conclusion, sexuality education programs based on high girl students' educational desire, characteristics of development, a teaching learning planning model, a health belief model were effective to improve sex-related knowledge, sexual attitudes and the self-efficacy of sexual behavior practice of commercial high school girl students. This result can contribute to expand the school nurse's role in the sex education area and to develop theory-based school health nursing.

The purpose of this study is to identify the factors affecting female college students' behaviors in seeking reproductive health information on the Internet and to explore the relationships among these factors. Based on the Health Belief Model(HBM) and the Theory of Planned Behavior(TPB), perceived sensitivity, perceived severity, perceived benefit, perceived barriers, subjective norms, perceived behavioral control, and affective evaluation were defined as key factors, and the study was designed accordingly. An online survey was distributed to female college students in Seoul through the university student's online community, 'Everytime.' The results showed that the intention of female college students to seek reproductive health information via the Internet was associated with higher perceived sensitivity, perceived benefit, and subjective norms, and lower perceived barriers. There were statistically significant differences between groups in terms of sexual experiences, experience with reproductive system disorders, and the level of health interest. We believe that this research outcome will contribute to assessing the level of awareness regarding reproductive health among female college students, thereby aiding in the development of online health information literacy education or related service programs by university libraries, health institutions, and similar entities targeting female college students.

This study examined the effects of media exposure and involvement on objectified body consciousness and appearance management behaviors. The subjects were 325 female university students in Daejeon and Chungnam Province. The research method was a survey, and the questionnaire was composed of media exposure and involvement, objectified body consciousness, appearance management behaviors, and subjects' demographic characteristics. The data were analyzed by descriptive statistics, Cronbach's ${\alpha}$, factor analysis, and regression analysis using SPSS program. The results were as follows. First, female university students used mass media for about 3.76 hours a day and showed a high level of media involvement. Second, three factors (body surveillance, body shame, and appearance control belief) emerged regarding objectified body consciousness with female university students showing a high level of objectified body consciousness. Third, six factors (make-up, plastic surgery, weight control, fashion, hair, and skin care) emerged regarding appearance management behaviors with female university students showing high intention to perform various appearance management behaviors. Fourth, media exposure and involvement had important effects on objectified body consciousness and appearance management behaviors, and media involvement was a more important variable than media exposure. Fifth, objectified body consciousness had important effects on appearance management behaviors. Body shame had more important effects on skin care, weight control, and plastic surgery behaviors, while body surveillance had more important effects on fashion, make-up, and hair management behaviors than other objectified consciousness factors. The implication of this study was that media involvement is a more important variable affecting objectified body consciousness and appearance management behaviors than media exposure, and among objectified body consciousness dimensions, body shame has important effects on more active appearance management behaviors like weight control and plastic surgery behaviors.

An objective of this paper is to discuss the didactical contracts which have been conceptualized by Brousseau. He modelled mathematics instruction as a game. In such game, didactical contracts existed as its own hidden rules which teacher and student should obey Brousseau introduced it to reveal certain hidden rules which regulates mathematics instruction. Those rules are implicit and reciprocal. In particular, it is not revealed until students break. He defined didactical contracts as teacher's behaviour and corresponding students 'behaviour in order to define it operationally. He he did not define it in psychological and epistemological dimension. But it is necessary to discuss teacher's belief system and epistemology, since teacher's behaviour in instruction is affected by them. He also did not discuss fully teacher's breaking of didactical contracts.

The purpose of this research is to apprehend what the power of professional learning community (PLC) to make home economics teachers participate is and how PLC activity contributes to reflective practice and change of participating home economics teachers by experiencing reflective practices. For this, self-reflective action research of Kemmis and McTaggart was conducted. Six home economics teachers participated voluntarily and totally 18 PLC sessions from May 31, 2013 to May 19, 2014 were held. Two themes of 'looking in classes' as a main practice theme and 'designing classes together' as a supporting theme were carried. Findings and conclusions of this study are as following. First, participants of PLC to get data and information on teaching and to solve problems with fellow teachers for better classes at first. However, they have become to comfort and sympathize each other about difficulties in school as home economics teachers. Second, through the PLC activity, they found they had uncomfortable belief about teaching and tried to practice solutions by critical and reflective thinking. Third, they put efforts in finding alternative framework of looking inside their classes for the fundamental improvement in teaching. For this, they formulated questionnaire to describe their own reflective practice through the alternative framework from a critical perspective in teaching, a view of student's learning, and a teacher's inner view for improvement of practice. Fourth, PLC activity for a year allowed them to combine theory and reality though reflective process by designing classes together and reflectively practicing them in classes.

In this paper, some factors such as the perspective of children, instructional materials(especially activities in textbooks for elementary school mathematics), and teacher's questioning styles are discussed as ones influenced on students' immersion in leaner-centered instruction. This discussion is based on the author's two implementations of the kind of two instructions. About the first theme, constructivists assert that even children who are in elementary school can have reflective abstracting ability. Teachers' asking questions with the belief differ from ones with traditional perspective of children, which is relevant the third factor. They value and respect learners' thinking outcomes, even though they are not sometimes wrong and have errors. Also, they have them opportunities to think different from others and to ask how they get their answers. To do these, they frequently ask open-ended questions, not closed. All of them is possible through the activities provided in textbooks. Some characteristics which can prompt such teacher's questions using activities in elementary mathematics textbooks are discussed.
