20 preservice teachers at college level participated in this study and interacted with students at elementary and middle school levels during science camp offered by science center in Taiwan. Preservice teachers displayed moderate (above the average, 4 point out of 5) understandings about scientific literacy and scientific views in all aspects of the nature of science before the camp. Then, the researchers designed science camp programs which were expected to promote students' scientific literacy; scientific knowledge, inquiry skills for experimentation as well as for argumentation, affective domain such as the attitude toward science and the understandings about nature of science and the relationship among STS (Science-Technology-Society), all of which were embedded in the programs. Preservice teachers seemed to perceive scientific literacy pretty well (over 4 point) before the camp, however, preservice teachers' understandings about scientific literacy were not much scored (around 3 point, but still moderate scores of average) as expected after concrete inquiry activities. The reasons why this happened could be that preservice teachers were not trained to employ theory into the context to be more practical or the researchers did not develop camp program which included the aspect of scientific literacy successfully. The discussion and implication were made in teacher education in that preservice teachers must be prepared how to bridge theory into practice, and informal science education in that educators at science centers must be trained to be experts in providing the envisioned educational programs to meet the goal of science education, scientific literacy.

The purpose of this study was to investigate the casual relationship between school adjustment, self-esteem and life satisfaction and academic achievement in elementary school students. This study utilized the NYPI's longitudinal data collected on elementary school students nationwide for 2012. Equation Modeling analysis was used to analyze 2,254 5th grade students' data. It was found that school adjustment was positively correlated with self-esteem, life satisfaction and academic achievement. School adjustment was directly associated with academic achievement. It was also confirmed that school adjustment indirectly explained academic achievement through self-esteem and life satisfaction. Future research directions and implications to teacher and institutions were discussed.
This study was carried to estimate the prevalence of obesity and to investigate the relationship between stress and obesity in children. The subjects were 508 children, who were randomly selected from the fifth and sixth grade at nine elementary schools in Kangnung. The height, body weight, waist and hip circumferences and body fat(%) were measured and the levels of stress were assessed by a questionnaire consisting of the following 3 domains ; 4 items for personal factors, 11 for home, and 18 for school. The prevalence of obesity in male and female children greatly varied by the indices from 2.5% and 1.7% when judged by BMI, 9.5% and 4.0% by obesity index, and 29.7% and 34.4% by body fat(%). The stress scores from personal(47.1%) and school (47.9%) factors were higher than the stress score from home(38.5%). The stress score from personal factors of female children is significantly higher than that of male children, but the stress score from home of female children is significantly lower than that of male children. The personal stress score and the total stress score of obese female children were significantly higher than those of non-obese female children. In male children, the obesity index(%) or body fat(%) have a significant positive correlation with the stress scores from over-expectation of parents, a lack of conversation with family, examinations, discontent about school, teacher's partiality to students, and sexual curiosity. The female children have a significantly positive correlation of obesity index (%) or body fat(%) with stress scores from appearance, quarrels of parents, and inferiority complex to brothers or sisters. These results suggested that counselling and education about not only balanced diet but also the strategies for actively coping with stress are needed to prevent and treat childhood obesity.
The purpose of this study is to find out the stress causes of the primary students in Korea, through the three major methods, life event score, multiple regression about stress causes and G.H.Q. path-diagram. A survey was made of 889 students who were selected among students of six primary schools in seoul and Ka-pyeng, from Sep. 28 to Oct. 2. 1992. The results of this study are summarized as follows : 1. Life event score Among the children's life events, (deaths of family) (degrade of school record) (the increase of absence days) (divorce of parents) (trouble with relationship) are high ranking in life event score. Besides, (scolded by teacher and parents) (beginning of extracurricular work) are spread stress causes. In conclusion, these stress causes are shown by two aspects, home, school, and so children are under stress circumstance in both places. These stress causes vary with area and sex. 2. Multiple regression about stress causes and G.H.Q. This study analysed how a stress caused by home life affects the children's health of mind and body. The most influential factors are , and these factors vary with area and sex. 3. Path-diagram This study proved that socio-psychological school environment raises children to secede from school, and this secession that operates as a stress cause affects children's health of mind and body. This serial process is analysed by path analysis, and made out a path-diagram. In conclusion, as expected socio-psychological,school environment affects the children's health of mind and body. This is shown by two aspects : positive, negative. This stress causes vary with area and sex.
Knowledge and data interpretation on statistical estimation was important to have statistical literacy that current curriculum was said not to satisfy. The author investigated mathematics teachers' MKT on statistical estimation concerning interpretation of confidence interval by using questionnaire and interview. SMK of teachers' confidence was limited to the area of textbooks to be difficult to interpret data of real life context. Most of teachers wrongly understood SMK of interpretation of confidence interval to have influence upon PCK making correction of students' wrong concept. SMK of samples and sampling distribution that were basic concept of reliability and confidence interval cognized representation of samples rather exactly not to understand importance and value of not only variability but also size of the sample exactly, and not to cognize appropriateness and needs of each stage from sampling to confidence interval estimation to have great difficulty at proper teaching of statistical estimation. PCK that had teaching method had problem of a lot of misconception. MKT of sample and sampling distribution that interpreted confidence interval had almost no relation with teachers' experience to require opportunity for development of teacher professionalism. Therefore, teachers were asked to estimate statistic and to get confidence interval and to understand concept of the sample and think much of not only relationship of each concept but also validity of estimated values, and to have knowledge enough to interpret data of real life contexts, and to think and discuss students' concepts. So, textbooks should introduce actual concepts at real life context to make use of exact orthography and to let teachers be reeducated for development of professionalism.
Augustus De Morgan became to be deeply interested in the education of pure mathematics since he came to teach in UCL because of the specific nature of natural philosophy lectures, the academical knowledge and reasoning powers of the students, and the negative attitudes of London society on mathematics. During his long tenure, he really tried his best to make his students understand the important concepts and the principles of pure mathematics, and logically explain the processes of inducing and proving the laws of pure mathematics. When he could not stay as a mere researcher, he had to concern himself with and pay attention to the problems of educating students. And then his teaching style was constructed in a specific way by the various attitudes about mathematics, the boundary relationship between the adjacent academical branches, and the social and systematic nature of UCL.

The subjects of this study were 64 young children aged 12 to 36 months old and their mothers and teachers. The attachment Q-set and an instrument for teachers' responsivity were used. Data were analyzed using SPSS 18.0, and Cronbach's and Pearson's r were calculated. The results were as follows. Teachers' consistency, warmth, and sensitivity were significantly correlated with the children's attachment to teachers. In addition, teachers' warm and sensitive responses were related to the children's attachment to mothers. Teachers' warm, sensitive, and responsive characteristics are emphasized for quality interactions between young children and teachers, since they contribute to the children's secure attachment to their mothers as well as teachers.

This study was intended to investigate the effect of aptitude of child care teacher of child care trainees on the stress of child care practice and management of stress as quality and aptitude of child care teachers are being discussed and necessity of revaluation on teaching practice of child care trainees are being brought up recently. First, as a result of collecting data from 268 child care trainees, stress of child care and teaching practice and stress management showed difference between grades. Secondly, among lower factors of aptitude of child care teachers, it was identified that stress is higher in a relationship between child care center director and guidance teachers when sociability with infants is lower. Thirdly, it was identified that teachers can cope with stress of child care and teaching practice when they have higher creativity, self-development, activeness, and positiveness among lower factors of aptitude of child care teachers.

The purpose of this study was to find the relationship between elementary school teachers' beliefs of inquiry and science performance assessment. To collect data for analyzing elementary school teachers' beliefs of inquiry and their practice of science performance assessment, the researcher was surveyed with elementary school teachers by open-ended questionnaires and interview. The findings of this study were as follows; First, Most of elementary school teachers beliefs of inquiry was shown as constructivist tendency. This view of inquiry involves watching and doing experiments, and the skills of thinking processes, in which learners make their own interpretations rather than merely acquiring preexisting knowledge structures. Second, for content knowledge, participants' preception about the target of science performance assessment involved assessing application of science knowledge rather than basic level of substantive knowledge. For inquiry process, participants' preception about the target of science performance assessment involved assessing the lower level of inquiry rather than the higher level of inquiry. Most of participants was measured using a paper and pencil test for the actual evaluation methods due to the ease and objectivity of the assessment, the lack of understanding how to perform the performance evaluation process and method. Especially, participants who recognize that the higher level of inquiry was used performance and informal mode of assessing.
This study was conducted to investigate the dietary behavior of day-care center teachers and their meal attitudes during meal time in Jeonju area. Self administered questionnaires were collected from 266 day-care center teachers who worked in a national(public) or private day-care center. The Statistical data analysis was conducted using SPSS v. 12.0. All subjects were women, and 64.7% were married(p<0.001), over more than 60% were junior college graduates(p<0.05), and 73.7% had salaries greater than 1,000,000 won(p<0.001). The breakfast skipping ratio of the subjects was very high, and about 66.5% of the respondents had irregular meals. The snack intake ratios of the subjects in private day-care centers were higher than the subjects in national(public) day-care centers(p<0.001). Approximately 56% of the subjects responded that education about eating is very important for providing balanced nutrition to young children. About 84% of subjects had no experience with the continuing-education program for teachers(p<0.01), and they wanted to know more about balanced nutrition. The meal attitude education score during meal time was $4.53{\pm}0.36$. The relationship between meal attitude education and the dietary behavior of day-care teachers was significantly different based on the "frequency of overeating"(p<0.05) and "self-recognition of eating habit"(p<0.05). These findings suggest that a nutrition education program for day-care center teachers should be developed so that they can effectively manage meal attitude education for young children and provide good nutrition for themselves.
