The purpose of this study is to present various examples of collaborative learning based on the Instruction of Internet in the 6th grade elementary school mathematics class. So we introduce the design method of classroom environment for classroom Internet and give example of various teaching methods. This study was conducted for nine months from March to November, 2016, one sixth grade of elementary school in D area. During this period, we conducted Instruction of Internet-based collaborative learning to classify typical teaching cases. We classified into 5 type collaborative learning. First, collaborative learning in the classroom. Second, remote collaborative learning between classroom and classroom. Third, Live participation classes. Forth, project collaborative learning. Fifth, using virtual reality in collaborative learning. In addition, we could identify that there is a difference compared to the conventional learning. It became possible to conduct collaborative learning with other students simultaneously or have opening class with both parents and teachers by using Youtube. These examples can be presented as a case to depart from traditional mathematics class in one classroom. In this regard, we will be able to provide several implications about teaching methods utilizing smart device and Internet in future classroom.

The purpose of this study was to examine the relationship between teacher's role and interaction patterns in mathematics classrooms. Teacher's role was divided into usual practices with students, usual practices with content and usual practices with students and contents, and interaction patterns were classified into report, inquiry and discussion. The subjects in this study were teachers and students in three fourth- grade classes in T elementary school located in Seoul. After the classes of every math teacher were observed, three teachers who played distinctively unique roles were selected in accordance with the results of the first-semester autonomous supervision, of open class for parents and of the instructional observation. Thus, there was a close relationship between the teacher roles and interaction patterns. And it's concluded that students are able to have a more discussion on each other's ideas in the student-centered classroom, and that teachers should perform active roles in that process. Given the findings of the study, there are some suggestions: First, the teachers appeared to fulfill consistent roles when their videotaped classes, study aids and performance assessment materials were analyzed, and they should play more active roles in mathematics class. Second, they should try to create the kinds of climate that encourages students to come up with ideas in an active manner. Third, earlier studies had focused on student-teacher interaction patterns, but this study found that the roles of the teachers depended on interaction with not only students but study aids and performance assessment materials, and that the interaction patterns hinged on their roles as well. Therefore more profound research efforts should be directed into this issue.

This study is intended to draw a scale for problem behaviors of young children. To achieve this, an empirical survey was carried out on experts from three groups of daycare center teachers, kindergarten teachers and early childhood education-majored professors. A total of 209 items were measured by the scale for young children's problem behaviors from the 1970s to now. The results showed that 96 of a total 209 items in 5 categories related to the scale for young children's problem behaviors were adopted as major items. Using these 96 major items in 5 categories, 17 out of 40 items in a peer relationship category, 13 out of 41 items in a development category, 20 out of 50 items in a fundamental habit category, 22 out of 38 items in a morality category, and 24 out of 40 items in an emotion category were adopted. Most items were adopted in the emotion category, whereas most items were rejected in the development category. Therefore, it is judged that their problem behaviors are caused mainly by anxiety, shrinking, unexpected behaviors, dependence on parents or teachers, and slow behaviors due to the latent negative emotions of young children at the developing stage.
This study examined the influence of the nutrient intake status, dietary habit, and academic stress of elementary school children on their academic achievement. Two-hundred and twenty-four fifth-graders in Bucheon-si, Gyeonggido were surveyed. The study included the 24 hr-recall, anthropometric measurement, assessment of stress level and academic achievement. The subjects were normal in height, weight and Rohrer index, but higher percentage of underweight was seen in girls and vice versa in boys. The overall nutrient intake and dietary habits were fairly good, but Ca and folate intake was less than 75% KDRIs and dietary habits of boys were inferior. Academic stress level of all the subjects was not high. In terms of academic performance and its relations with nutrient intake, the more the amount of nutrient intake, the higher the academic performance. Especially, it was true for the energy, protein, phosphorus, potassium, zinc, polyunsaturated fatty acids, and n-6 fatty acid intakes (p < 0.05). The overall academic performance was higher for those who eating-out less frequently. Children with higher comprehensive dietary habit scores have shown better academic performance (p < 0.05). Less stress implied to those shown higher academic achievement while those with relatively poor academic performance showed high stress level since their grade did not improve as much as they anticipated. In conclusion, the academic achievement was higher for those who have a better nutritional status, better dietary habits, and lower stress levels. Therefore, it is critical for nutritionists, parents, and teachers to improve the nutritional status and dietary habits as well as to help them manage their stress levels, which will eventually contribute to an enhanced academic performance.
The purpose of this study was to find out the image as science teachers recognized by pre-service science teachers. The data was collected from 312 pre-service science teachers from Kyungpook National University in Daegu and participants were asked to write about the image of science teachers they liked most and least in their secondary school years freely. The result of this research was as follows. The image as science teachers categorized 2 factors: science instructional situation, image of science teacher. Each factor was subdivided into more detailed ones. First of all, 'science instructional situation' category subdivided into lesson style, teaching-learning materials, teaching methods, and class atmosphere. In lesson style, 'experiment' and 'observation' gained the most favorable comments, and questioning-answering gained the least. In teaching-learning materials, print materials such as handouts, worksheets, reports were the most liked, and 'writing on the blackboard' was the least liked. In teaching methods, the 'detailed and systematic explanation of the theory and concepts' was preferred to rote learning and memorization lacking explanation. In class atmosphere, friendly and free atmosphere was the most preferred, and uncomfortable, boring one was the least preferred. Secondly, in 'image of the science teachers' category and 'quality as the teachers' sub-category, thoughtful and considerate teachers who respect students' personality was the most preferred. On the contrary, they didn't prefer teachers who were indifferent and humiliated students. Finally in 'characteristics of the teachers' sub-category, the participants liked clear, energetic voice, and mild expression, and they didn't like formal style, overly fancy clothes, etc. Based on the result of this study, more empirical study on the teachers' image is needed, and the thoughts of educational administrators, students, parents, and teachers should be reflected because an undesirable teacher can be advised and get opportunity to be a better teacher.
The research attempted to propose directions for improving evaluation of science gifted educational institutions affiliated with universities through its meta-evaluation. A survey questionnaire was developed and responded by 25 representatives of 25 science gifted educational institutions and 9 evaluation committee members in February 2008. According to research results, it was found that reference-criteria and categories for evaluation were abstract and did not reflect varied characteristics of individual institutions. Evaluation of outcomes mainly emphasized student number admitted by science high schools and science gifted school. Evaluation was performed for the sake of judging ranks. In addition, research capacity of institutions was not even considered as an evaluation element. For its improvement, the followings were suggested: First, evaluation should be functioned as consulting. Second, evaluation criteria are presented as concrete as it can be. Third, on-site evaluation should be introduced Fourth, evaluation process and results should be publicized Fifth, satisfaction by student and parents should be also included. Furthermore, exemplary cases of science gifted educational institutions should be identified and rewarded, and their management strategies should be disseminated with other institutions.

The purpose of this research is to investigate the type of curriculum implementation and the level of teachers´ participation in the decision making process and their satisfaction related to the Technology and Home Economics, in middle school. The survey data were collected by mail from 284 $\ulcorner$Technology and Home Economics$\lrcorner$teachers for the first graders in middle school from July to August. 2001. The results showed that $\ulcorner$Technology and Home Economics$\lrcorner$ were mainly taught by Home Economics teachers alone. The teachers teaching whole subject alone were more anxious about lacks of facilities and confidence of students and parents as well as lacks of skills and knowledge of the non-major part. and student´s interest in the subject than team teaching teachers were. The team teaching teachers were more likely to be participated in the process of deciding curriculum implementation types and to be satisfied with the type of curriculum implementation. The satisfaction with curriculum implementation was mainly affected by the Participation in the decision making process as well as the type of curriculum implementation.

The purpose of this study was to examine the factors associated with adolescents' attitude toward volunteer activities. Analyses of data provided by 450 adolescents attending secondary schools in Gyeongnam Province suggested the following results. First, adolescents' attitude toward volunteer activities differed by gender, religion, and academic grades. Adolescents who were girls, who had religions, and whose academic grades were higher showed higher levels of positive attitude toward volunteer activities than their counterparts who were boys, who did not have religion and whose academic standing was lower. Second, adolescents' attitude toward volunteer activities significantly differed by the family factor. To be specific, parental attention, parental support and family's participation in volunteer work made differences to the adolescents' attitude toward volunteer activities. Third, the adolescents took significantly different attitudes toward voluntary activities according to the school factor. Significant differences were found according to attention and support from teachers. The students whose teachers had more interest in voluntary service and whose teachers offered more aid took a more positive attitude to voluntary service. Forth, some of the personal, family, and school factors were associated with adolescents' attitude toward volunteer activities. Among the personal factors, gender, religion, academic standing, and morality were associated with dolescents' attitude toward volunteer activities. Those who were girls, who were religious, whose academic standing was higher, and who were more moral took a more positive attitude toward volunteer activities. Among family and school factors, parental attention/support and attention and support from teachers affected the voluntary service attitude of the adolescents. The students whose parents had more interest and gave more support and whose teachers showed more interest and offered more support took a more positive attitude toward volunteer activities. Therefore parental attention and support were identified as the variable to make the best prediction of the adolescents' positive attitude toward volunteer activities.
Two new and one unrecorded hybrids of the genus Asplenium were newly found in Korea. They were proved to be hybrid based on intermediate morphology between putative parents. The first hybrid is $A.{\times}uiryeongse$ C.S. Lee & K. Lee (Aspleniaceae), nom. nov. (vernacular name: geo-mi-sa-cheol-go-sa-ri). This new hydrid is a cross between the Asian walking fern, A. ruprechtii and A. pekinens in Uiryeong-gil, Mt. Bukansan, Seoul, Korea. The other new one occurs in Mt. Seongsan in Yeoncheon-gun, Gyeonggi-do, Korea, $A.{\times}montanus$ C.S. Lee & K. Lee, nom. nov. (vernacular name: san-kko-ri-go-sa-ri) which might have experienced multiple hybridization events between A. ruprechtii ${\times}$ A. trichomanes and A. incisum following the hybrid between A. ruprechtii and A. trichomanes. In addition, one unrecorded hybrid, $A.{\times}kitazawae$ Kurata & Hutoh (vernacular name: geo-mi-dol-dam-go-sa-ri), reported first from Japan, is found in natural habitats in Do-dong, Daegu-si, and is a hybrid, between the Asian walking fern and A. sarelli. These hybrid taxa grow in sympatric regions with both putative parental species. The diagnostic characters for each taxon and evidence for their hybridization have been suggested. Descriptions, illustrations, and photographs of these hybrid taxa in their habitats are provided from Korea.
The factors for the childhood onset obesity were assessed to provide informations for the nutrition education program targeting the primary school children. The subjects of this study were 529 primary school children in Iksan City, Jeon-buk Province. Children were classified into obese(236) and control(293) groups by the obesity index. Anthropometric measurement dietary intake through 24-hour recall method, blood analysis and questionnaire response including nutritional knowledge and attitude, body image recognition and eating habits were conducted The mean age of subject was 12.0 years. The average body weight(p<0.001), BMI(p<0.001), and obesity index(p<0.001) in obese group were significantly different from those in control group; their values in the former were 26.5 kg/m2 and $37.7\%$ and 43.0 kg, 19.8 kg/m2 and $3.2\%$ in the latter, respectively. The average scores of self-satisfaction were significantly different in two groups (p<0.001), 31.2, and 34.1, respectively. Among the obese subjects, $60.6\%$ were unsatisfied or very unsatisfied with their body image, and $76.5\%$ had experiences of weight control and $67.5\%$ took diet control as a weight control method Among mothers of obese subjects, $89.1\%$ were unsatisfied with their children's body image. $64.4\%$ of obese subjects had obese parents. Average intake of energy were $76.7\%$ of RDA in obese group and $74.9\%$ of RDA in control group. Average intake of cereals(p<0.01), potatoes & starch(p<0.01) and eggs(p<0.01) between obese and control subjects were significantly different; 295.4g, 76.2g, 55.6g in the former and 277.9g, 38.1g, 45.6g in the latter, respectively. The mean serum triglyceride(p<0.05), GPT(p<0.05), hemoglobin(p<0.001) concentration of the obses and control subjects were significantly different; in the former, 103.6mg/dL, 24.6U/L, 13.4g/dL, and in the latter, 93.7mg/dL, 19.9U/L, 13.1g/dL, respectively, The results suggest that practical nutrition education for the prevention of childhood onset obese should be provided to primary school children.
