  • 측정 영역에 대한 교과서 분석 연구는 초등 수학 교육에서 측정이 차지하는 중요성과 학교 수학에서 교과서가 끼치는 영향에 비하여 상대적으로 부족한 편이다. 이에 본 연구에서는 학생들이 가장 먼저 학습하게 되는 길이와 시간에 관한 내용을 중심으로 2007 개정 교육과정과 2009 개정 교육과정에 따른 수학 교과서를 비교 분석하였다. 구체적으로 측정의 전반적인 교수 학습 요소, 측정의 학습 내용에 특화된 교수 학습 요소, 수학 교과 역량이라는 세 가지 분석 기준을 활용하였다. 분석 결과, 측정의 전반적인 교수 학습 요소 중 실생활 및 타교과와의 연계는 일관되게 잘 반영되어 있었다. 측정의 학습 내용에 특화된 교수 학습 요소 중 용어의 의미와 계산의 필요성에 대한 내용은 적절하게 구현되었으나, 단위의 필요성, 적절한 단위 선택, 오개념 활용에 관한 내용은 다소 미흡한 편이었다. 마지막으로 수학 교과 역량에서는 주로 문제 해결, 의사소통, 추론이 강조되고 있었다. 이와 같은 분석 결과를 토대로 길이와 시간에 관한 지도 방향 및 차기 교과서 개발에 대한 시사점을 도출하였다.

  • This study was a research study to find out the real picture and practice of student obesity control by primary, middle and high school school nurses. The study sampled 196 school nurses working in the Busan City and Northern Gyungsang Province, who agreed on the purpose of the study. When it comes to the study process, at the meeting of the whole school nurses, the researcher explained the purpose of the study and asked them to complete questionnaires and return on the spot. The study is designed to provide basic data for school nurses in field to systematically and efficiently control student obesity by examining perception of school obesity control and the real picture or practice of obesity control as well as its problems. The study used SPSS 10.0 to analyze data. The results are as follows: Annual plans about obesity control appeared significant at the primary school, 89.3%, higher than 77.3% of the middle and high school(p<0.05). Annual project evaluation showed a significant difference by regions, 56.0% of metro cities vs. small cities(p<0.01). The number of measuring weight of obese students was higher at the primary school than at the middle and high school(p<0.05). Also small cities conducted the weight measurement more often than metro cities(p<0.001). Among the health education methods for obesity, counseling appeared statistically significant(p<.01). The health education showed a significant difference in more experienced school nurses. Among the educational media, environment postings were used at the primary school, 24.0%, higher than 5.3% of the middle and high school. It showed a significant difference(p<.001). OHP or epidiascopes were used at the primary school, 36.4%, significantly higher than the middle and high school(p<.001). In addition, computer was used at the primary school, 21.5%, higher than the middle and high school(p<.05). Problems of obesity education data included a lack of textbooks and programs and a short of educational media. However it didnt show a significant difference in schools or in regions. Counseling activities for obesity showed a significant difference in schools(p<.01) and in regions(p<.001). When parents with obese students were in counseling, those in their 20s used home correspondence and those in their 30s and 40s used phone call(p<.01). The rate of equipment to measure obesity was higher at the middle and high school than the primary school, showing a significant difference(p<.001). Therefore, regular health education curriculums for school nurses should be systematically created to promote student health. Furthermore, it needs to make standard textbooks for health education by grades as well as by levels and to develop various educational programs and educational media.

  • Objectives Bedding in childcare centers (CCCs) can hold house dust mite (HDM) allergens. This study examined whether HDM allergen levels can be reduced through the distribution of an educational newsletter on bedding control to parents of CCC children in Korea. Methods All 38 CCCs were measured for Der 1 (sum of Der f 1 and Der p 1) concentrations on classroom floors and bedding before the intervention. Educational newsletters on children's bedding control were sent to 21 CCCs by mail, and teachers were asked to distribute the newsletters to the parents of the children (intervention group). The remaining 17 CCCs were not sent newsletters (control group). The measurement of Der 1 concentrations in 38 CCCs was repeated after the intervention. Dust samples were collected with a vacuum cleaner and analyzed using enzyme-linked immunosorbent assay methods. Results The Der 1 concentrations on the bedding were significantly higher than those on the floors in 38 CCCs at baseline (p < 0.05). Although changes of the Der 1 concentrations for the control group (n=17) were not significant, Der 1 concentrations for the intervention group (n=21) decreased significantly from 2077.9 ng/g dust to 963.5 ng/g dust on the floors and from 3683.9 ng/g dust to 610.4 ng/g dust on bedding (p < 0.05). Conclusions The distribution of educational newsletters on bedding control to parents may be an effective means of controlling HDMs in CCCs.

  • The purpose of this study is to measure and analyze primary causes of indoor air pollution, including carbon dioxide, minute dust, and total volatile organic compounds, for each room before the beginning of a class through the time of discharge after the end of the class in general classrooms, computer rooms, and science rooms of three newly-established schools that opened in 2006, examine properties of indoor air environment in each room by educational activities at school, and determine effective management schemes; the results of this study can be summarized as follows: 1) As for implications for each item found in the mean for each place, since minute dust (PM10) was more likely to occur in time slots full of students' activities, such as a traveling class and a recess, than in the middle of a class and could be expected fully, it is necessary to make a scheme for cleaning in order to reduce minute dust within a room, for example, by usually using a vacuum cleaner indoors. 2) While carbon dioxide was expected to vary with the differences in the amount of breath between higher-graders and lower-graders in a general classroom but showed insignificant difference by grades, showing differences in pollution by four times at a maximum according to the opening of a window as expected, it is necessary to implement artificial or natural ventilation and take a positive measure, for example, by presenting a concrete ventilation scheme, in order to improve indoor air pollution at a room practice. 3) Total volatile organic compounds were found to exceed the standard by more than twice in general classrooms, science rooms, and computer rooms of the schools because of building materials, furnitures including desks and chairs, panels and boards for environment beautification, and items which could be detected even from students' clothes; while a field directly-reading tool was used, obtaining high reliability for the results, it is necessary to apply an analytical method based on process test separately for actual correct measurement if a significantly great amount of total volatile organic compounds appear as compared with other schools due to measuring expenses and consecutive measurements. 4) Since formaldehyde (HCHO) was generally found to exceed the standard in general classrooms, science rooms, and computer rooms, it is necessary to establish and operate a ventilator during a class in a computer room which requires airtightness and a science room in which an organic compound should be used for a class.

  • The purpose of this study is to explore 'Flow Experience' of those studying English speaking and listening in the e-Learning environment. The exploration of flow experience in this study is based on the literature research of Csikszentmihalyi's flow models and other studies. There have been many studies on flow experience focusing on arts, leisure and sports in accordance with Csikszentmihalyi's original theory, however, his flow theory has recently been adapted to the educational field. Nonetheless, it is in the e-learning environment, rather than the face-to-face traditional teaming environment, that there is not enough flow state measurement scale. Therefore, it is important to develop as a stepping stone a flow state scale for those who study English speaking and listening by the cyber-native-speaker on e-Learning environment to improve their satisfaction and achievement.

  • This study's aim was to analyze the effect of a project activity based on role play on 5-year-olds' mathematical ability. The participants of this study were 56 5-year-olds from two educational institutions for young children located in two metropolitan cities in Korea. The experimental group (n=28) participated in a project activity based on role play, while the comparative group (n=28) did not. The "Mart Play" project activity based on role play was developed emergently by the children and teachers of the experimental group. The children's mathematical ability was measured before and after the experiment. The data were analyzed using t-test and ANCOVA. As a result, the project activity based on role play had an effect on the improvement of 5-year-olds' mathematical ability generally, but not on their measurement ability.

  • The aim of this study was to promote extensive use of strain gage for accurate measurement in the area of farm machinery research. The results are summarized as follows. 1. Although many strain gate transducers commercially available such as load-cells , accelerometers and pressure transducers have been used in the area of farm machinery research, many types of transducers had to be developed due to the inadaptability or high cost commercial transducers, in many instances. 2. A strain -gaged cantilever beam could be used as a good educational material to demonstrate the methods of Wheatstone bridge arrangement, calibration and theoreticval computation. A ring type load-cell and shaft torque transducer also could be used for the same purpose. 3. The torque and angular speed transducers for an auto-feed thresher and the displacement and pressure transducers for a rice whitener were made and gave satisfactory results. 4. Based on the above results, it is possible to develop simple and low-cost transducers to measure displacement, angular speed , torque and pressure of farm machine elements.

  • This paper investigates how two different modes of feedback (selective vs. comprehensive) affect selected students' writing development in terms of three different types of measurement (accuracy, fluency, and complexity). 139 university students participated in the study, and 278 writing samples were analyzed. The results of the study indicate that participants who received selective feedback wrote more accurately and fluently than their counterparts. However, in terms of complexity, both selective and comprehensive groups showed no sign of improvement in semester-based investigations. The results of this study support Skehan's (2009) theory of trade-off effects, suggesting that 'natural' tension exists between accuracy and complexity when resources are limited. Moreover, this finding contrasts with the theory of Cognition Hypothesis, which proposes that task complexity will be associated with increases in complexity and accuracy. In the study, selected participants (N=21) strongly nominated their error sources as unfamiliarity toward using key words, usage, transition, and sentence types. This study not only contributes to the accumulation of our current knowledge in the related area of theory, but offers educational implications for those who are dealing with intermediate-level students when deciding what particular teaching content should constitute a priority within a limited instructional period.
