The purpose of this study is to investigate the effects of cognitive activity on cognitive activities that students imagine and cope with continuously changing quantitative changes in functional tasks represented by linguistic expressions, table of value, and geometric patterns, We identified covariational reasoning levels and investigated the characteristics of students' reasoning process according to the levels of covariational reasoning in the elementary quantitative problem situations. Participants were seven 4th grade elementary students using the questionnaires. The selected students were given study materials. We observed the students' activity sheets and conducted in-depth interviews. As a result of the study, the students' covariational reasoning level for two quantities that are continuously covaried was found to be five, and different reasoning process was shown in quantitative problem situations according to students' covariational reasoning levels. In particular, students with low covariational level had difficulty in grasping the two variables and solved the problem mainly by using the table of value, while the students with the level of chunky and smooth continuous covariation were different from those who considered the flow of time variables. Based on the results of the study, we suggested that various problems related with continuous covariation should be provided and the meanings of the tasks should be analyzed by the teachers.

This study investigated when and how science gifted students decide their career planning. We used semi-structured survey and additional interviews from the students of Science High School in Daejeon area. We found 39.1% of science gifted students in 10th grade formed their career planning from their middle school periods. They had comparatively high levels of parenting support. The students chose their career fields based on their interests and aptitudes. However, some students were able to try and never give up with self confidence even when they had low scores, and teacher's reinforcements influenced positively. 71.3% of students thought that the grades take up the achievement of career development. Besides, the career programs which had specific purposes and directions were very effective by 33.3%~64.4%. Otherwise the effects were low as 2.3%~18.4%. Especially, R&E research programs didn't effect on students' career development and some students even frustrated with research. Based on the results, we need to reflect current career education and develop worthwhile career development programs for the science gifted students.

This study had conducted to push our society for getting some proper measures of the anti-drug abuse and adopting this study as a fundamental data for the school health education. Sample subjects were the 3rd grade of high school in Chungnam Province and the number were 1,014. The data had been collected on Dec. 3th-8th, 1990 according to the tool of Institute on Drug Abuse of Korea. And then Frequency and $x^2-test$ were need to analyse of data by SPSS-X program. The results of this study could be summarized as follows. 1. They had used 14 kinds of drugs: $70.1\%$ of the subjects students used alcohol, $69.2\%$ analgesics, $38.6\%$ cigarette, $15.0\%$ stimulants, $14.7\%$ antitussives, $11.2\%$ antithistamines, $8.9\%$ hypnotics, $7.1\%$tranquilizers, $4.2\%$ inhalants, $2.3\%$ marijuana, $1.4\%$ hallucinogens, $0.9\%$ cocaine, $0.6\%$ amphetamines, and $0.6\%$narcotics. The boys' drug using rate is higher than girls' except in analgesics and stimulants. 2. With respect to misbehaving, $43.0\%$ of the students said they had pop houses, $42.4\%$ adult video, $17.4\%$ unexcused absence from school, $11.0\%$ dangerous weapon, $9.1\%$ sexual intercourse, $70.1\%$ disappearance from home, 8.0% blackmail, and $6.0\%$ assault. In every kinds of misbehaving, the boys' misbehaving rate is higher than the girls'. 3. Almost every kinds of drugs have the students first used at the age of 15 through. 18. And $13.8\%$ of the students smoked every da·y and $1.7\%$ drank every day. 4. The frequency of the drug using such as cigarette (p<.01), marijuana (p<.05), cocaine (p<.05) and narcotics (p<.05) showed the stastically significant differences according to the religions of the subjects 5. The subjects who has complaints about someone use more drugs than the ones who doesn't, and who doesn't have any complaints about five elements have never used drugs such as marijuana, cocaine, amphetamines, narcotics, hallucinogens, and inhalants. 6. The drug using subjects have the more experiences of adult video, pop houses, and unexcused absent from school than the non-drug using ones.

The purpose of this study is to find out the perception of parents in order to develop a software education program for elementary students convergence with English. A survey was administered to 120 parents asking perceptions about SW education in schools and preferences about English-SW convergence programs for their elementary school children. The results shows that the parents think the current 17 hours of SW education provided at elementary schools is not enough and also they hoped the education started at an earlier grade than the current 5th·6th graders. Most parents perceived English is helpful in SW education and answered strongly for the need of English-SW convergence programs. A two-week program with the ratio of 6(SW):4(English) was the most preferred according to the study. As for regional differences, the parents in Seoul and Gyeonggi Province wanted SW education as after-school programs in elementary schools whereas, parents in Chungcheong Province expected SW education programs be provided from near-by universities. It is hoped that with the results of this study various English-SW education programs are developed and operated.

The purpose of this paper is to develop RPG based learning content for English low-achievers at elementary school and to verify the educational effectiveness of this content. Design strategies were elicited by reviewing curriculum and literature. Educational RPG was developed based on ADDIE model. The researchers implemented them in four 5th-grade English low-achievers for two months. Free writing, interviews and observations of the homeroom teacher were conducted to verify the effectiveness of the content. As a result, English low-achieving students became interested in RPG itself, raised their expectations and became more satisfied in learning. When students completed missions while playing games, they gained satisfaction and were challenged by the new missions. This had a positive effect on learning motivation, or "continuing motivation" as mentioned by Keller.

Objectives As public concern on possible harmful effects of mobile phone in children has been raised, information of epidemiological characteristics of mobile phone use in children and adolescents will be essential for public health policy. Methods Using three databases (n=21,693) collected from 2008 to 2011, we examined characteristics of mobile phone ownership and use, and socioeconomic positions (SEP) in Korean children and adolescents. Results The ownership rate and the amount of mobile phone use were higher in females than males, in higher school grades than lower grades, and at 2011 than 2008. The average age of first mobile phone ownership was shown to decrease from 12.5 years in currently high school students to 8.4 years in currently elementary school students at 2011. More than 90% of children in the 5th grade owned a mobile phone. More children owned a mobile phone in lower SEP communities than in higher SEP. Children with parents educated less than those with parents educated more were more likely to own and use mobile phone. Conclusions Considering the epidemiological characteristics of mobile phone use, precautionary measures to prevent unnecessary exposure to mobile phones are needed in children and adolescents.

This study is to consider hypotheses with integral view on the respect of creative thinking. Subjects of this study are Korean students in the 5th grade who participated in the Field Trip Contest of the second Korean Youth Science Festival, an openended inquiry investigation. Objectives of this study are as follows: 1) to measure the inquiry level of the Field Trip Contest activity 2) to find how many hypotheses were made on different types in the inquiry investigation 3) to measure the quality level of hypotheses made in the scientific inquiry investigation 4) to find out the correlation between the 1st and 2nd hypotheses and the final activity score in the two staged scientific investigation In the consequence of it, inquiry level of the Field Trip Contest was very high with good activity topics and openended way of investigation. Hypotheses were made in the prediction, plan, and conclusion parts in the field trip activity report. They used hypothesis-as-prediction typed statements(3.41/team) more than hypothesis-as-explanation(1.28/team) and descriptive hypothesis(0.03/team) types. Content-related hypothesis(5.03/team) and process-related hypothesis(6.16/team) were usually coupled each other. Most of them had difficulties in hypothesis-from-evidence(0.31/team, 10/32 teams) in the comparison of hypothesis-from-simple conjecture(10.62/team). The quality level of content-related hypotheses(0.74point/statement) and process-related hypotheses(1.98point/statement) were very low by the hypothesis-quality scale(Quinn and George, 1975) for the content-related hypotheses and the process-related hypothesis quality scale developed in this study. There was considerable correlation between the activity score and the 1st and 2nd hypothesis in the 2 staged inquiry investigations with the 2nd and 3rd topics($0.41{\ast}$, $0.59{\ast}{\ast}$ repectively).

Children are an important target of health promotion activities due to the life long effects. Therefore, the purpose of this study was to evaluate a nutrition education program offered to primary school students by community health centers. Eight hundred and twenty-six children from 4 primary schools in Seoul voluntarily attended the program. Teachers taught the classes with materials that were provided to them. The subjects were asked to fill out a questionnaire before and then after completion of the program. The data were analysed by SPSS. The results showed that there were significant positive differences in the children's nutrition knowledge scores after the program (p<0.001). In terms of dietary attitude, the rate of 'yes' responses, as a desirable answer to many questions, had increased (p<0.001); however, this positive change in scores was not statistically significant. For dietary habit changes, it was shown that the proportion of children regularly eating breakfast five days a week had improved to 3.3%. And the proportion of children eating fast foods and instant foods decreased. There was no change in fruit intake, but vegetable intake increased (p<0.001). However, the children's overall dietary habit scores did not show a significant change. In the evaluation of the program, 52.3% of the subjects answered that was helpful, and they viewed 'fast food' as the most interesting topic, whereas 'nutrition labeling' was the most difficult topic in the program. The program's effectiveness was positive in terms of enhancing the 'nutrition knowledge', 'dietary attitudes', and 'dietary habits' of the children. Therefore, the above results indicate that this type of program, provided by community health centers, was effective for nutrition education.
