The purpose of this study was to investigate relations between middle school science teachers' perception of students' learning styles and their teaching style. Data were collected by in-depth individual interviews with 20 experienced science teachers (14 years of teaching experience in average). Results indicated four categories of the relations: i.e. teachers implemented their teaching style (1) matching students' learning styles, (2) supplementing students' insufficient learning styles, (3) teacher-centered, but matching the diverse students' learning styles, and (4) based on their values and convictions. In general, teaching styles of the teachers did not match with their perceptions of students' learning styles. Instead, their teaching styles seemed to be more affected by their personal values and convictions.

The purpose of this study was to investigate beginning earth science teachers' perceptions about Learning in Geologic Field Trip. The hundred and sixteen high school earth science teachers who were in the training for their promotion answered the questionnaire of Learning in Geologic Field Trip. It was divided into five parts: needs and educational values, teachers' experiences and their difficulties, and desirable teaching methods of Learning in Geologic Field Trip. Results indicated that the participants perceived Learning in Geologic Field Trip important in earth science education and responded positively to the educational values of Learning in Geologic Field Trip. Most of the beginning teachers had experience of geologic field trip, but did not learn how to teach it to their students during the geologic field trip in the pre-service training program. It was shown that only a few teachers had experience of geologic field trip and of teaching students in the outdoor of geologic fields after they became a classroom teacher. Most of the participants perceived that teaching students about the geologic field trip is difficult because of lack of their experience. In order to overcome the difficulty, teachers suggested that they need to learn how to teach the geologic field trip to students through their in-service training. leachers suggested that a desirable teaching method of the geologic field trip is to provide teachers with a teacher's manual including geological explanation and information about field trip sites before their visit so that they can scaffold it and facilitate the students' cooperative group activity during the field trip. As a follow up activity, the participants agreed that the presentation and discussion about the results should concur.

Objectives: Few studies have focused on health behaviors and health status among teachers even though these are one of principles and values of WHO's Health Promoting Schools. In this study, we described health behaviors and health status among teachers and explored the differences of these by personal and school characteristics. Methods: A stratified and random cluster sampling design was used to obtain a cross-sectional sample. A total of 59 elementary, middle and high schools in Seoul and Gyeonggi areas were included in which 333 teachers (males 40.6%, females 59.4%) participated in this survey. Chi-square tests were conducted with SPSS 17.1. Results: Overall, health behaviors and health status among teachers were better than the general public according to Korea National Health and Nutrition Examination Survey. Male and middle/high school teachers had higher prevalence of alcohol dependence and of driving under the influence of alcohol. Also, their rate of wearing seat belts were lower compare to female. In other hand, female, health and nutrition teachers, rural school teachers had lower prevalence of meeting recommended levels of physical activity. Underweight were more prevalent to them in contrast to male with higher prevalence of obesity. In addition, teachers of health promoting schools were not likely to ride on a car with a drunk driver. They also have a lower prevalence of skipping breakfast and have higher positive perception of health for themselves. Conclusion: Teachers' health should be given higher concerns as a key component of school based health promotion. Gender and age specific programs should be considered to develop health promoting programs for them.

Mathematical modeling has been a crucial topic in mathematics education as students' problem solving competency are regarded as a core skill for future society. Despite of the importance of mathematical modeling in school mathematics, there have been very limited studies relating pre-service teachers' knowledge and perceptions on mathematical modeling. In this vein, this study aimed to investigate pe-service mathematics teachers' perceptions on mathematical model, mathematical modeling and educational use of mathematical modeling, and their relationships. The current study utilized a survey consisted of 18 items. The responses of 210 pre-service mathematics teachers to the survey items were quantitatively analyzed using descriptive statistics, analysis of variance, exploratory and confirmatory factor analysis, the structural equation model, and multi group analysis. The results of analysis of variance revealed that pre-service teachers in difference groups (majors, grades, and experiences with mathematical modeling) showed statistically significant differences in mean values. Moreover, according to the results from the structural equation modeling analysis, pre-service mathematics teachers' perceptions on mathematical model and modeling affected their perceptions on educational use of mathematical modeling. In addition, depending on their pre-experiences with mathematical modeling, pre-service teachers represented a different relationship between perceptions on mathematical modeling and educational use of mathematical modeling. Implications for future studies and mathematics classrooms were discussed.

This study was performed to investigate the degree of different stresses and to search the influence of food habit and nutrient intakes at stress situation in university students and secondary school teachers. The data was collected by questionnaire method and searched nutrient intakes by 24 hours recall. The subjects were 282 students and 152 high school teacher in Kyunggi do. Physical status was no difference with two groups. Energy intake of teachers was lower than that of students, but the intakes of vitamin A and C were high in teachers' group. The university students had more stress situation than teachers in almost kind of stresses except overload stress. Self-diagnosed dietary habits were better in the group of teacher. Especially smoke and alcohol drink behavior were correlated with nutrient intakes in male teachers and students. The quantity of nutrient of nutrient intakes was correlated with different kind of stress. The stress of life event was correlated with the intakes of carbohydrate, minerals, thiamin and riboflavin, and the deprivation was with iron and vitamin A in teachers' group. The intake of almost nutrients was correlated with the stress of noise in students' group. By the analysis of stepwise multiple regression, although the $R^2$ values were very low, vitamin C intake was influenced in the factor at the stress of life events($R^2$=0.025), self-efface($R^2$=0.030) and noise($R^2$=0.020), thiamin was at food induced stress ($R^2$=0.021) and vitamin A was at the stress of type A behavior($R^2$=0.022) and anxiety response($R^2$=0.014). Therefore, we could concluded that different kind of stresses were influenced in dietary behavior and nutrient intakes. More research would be needed at the aspects of health promotion in the stressful situation of modern society.

The purpose of this study was to examine the relations between maternal traditional-modern values, childrearing practices and children's social behaviors. The subjects were 500 fifth grade elementary school children and their mothers, and teachers, and peers in the same classroom. The data were collected through questionnaires on maternal traditional values, perceived maternal childrearing practices, and children's social behaviors. Traditional maternal values focused on familial collectivism and politeness. The major results were as follows: (1) Maternal traditional values were positively related to childrearing practices in both maternal affection rational guidance and authoritarian control. (2) Maternal traditional values did not directly influence children's social behavior but showed an indirect moderating effect through maternal childrearing practices. Implications were discussed in terms of the importance of traditional values on childrearing behavior as well as the development of children.
