7차 교육과정(1997)의 도입으로 확률 및 통계단원이 중등 수학 교과과정에서 독자적인 영역을 확보하게 된 만큼 그 목적에 부합하면서 효율적이고 흥미를 유발시킬 수 있도록 교과교육 매체 개발에 투자를 해야 할 시기라고 본다. 교과교육 매체의 한 방법으로 Excel을 중학 교육과정에 나타난 통계교과내용을 지원하게끔 Excel의 기본 메뉴, 분석도구, 그리고 Visual Basic을 활용한 매크로 작성방법에 대하여 다루었다.

In this paper, we analyze and discuss the trend of the probability and statistics problems that have been made in the public secondary school teacher employment exam for mathematics teachers. In order to properly teach the national mathematics curriculum in 2015 in terms of content and function, we investigate the probability and statistics contents that a mathematics teachers should know. We also analyze the contents and trends of the items that have been submitted for 15 years in public secondary school teacher employment exam, and discuss the contents, scope, level and direction of the future contents. In conclusion, considering the significance of the Big Data in the 4th industrial revolution, the problems of statistical thinking of data and probability, exploratory data analysis, sample survey, and statistical inference are needed more.

The goal of this study was to analyze students' views about statistical themes in Mongolian secondary schools in Ulaanbaatar. To this end, 129 9th grade students were stratified random sampling at two secondary schools in Ulaanbaatar, Mongolia, and a survey was conducted on them. The attitude survey focused on six factors contributing to the attitude: affective, cognitive competency, value, difficulty, interest, and student effort. The results show that students believed their statistical knowledge and skills have increased compared to the beginning of the courses. Furthermore, the survey revealed that they perceived statistics as neither an easy nor a difficult subject. Students' interest in statistics was neutral in general. These results suggest a need to develop effective and innovative statistical teaching and learning methods that can attract attention to statistical topics.

The Ministry of Education Science, and Technology proclamated the school curriculum of the republic of Korea at 9 August 2011. The characteristics of this curriculum are as follows; effective learning of student-centered, group of grade, group of category, concentration study, reduction of study subjects, extension of school autonomy, elective curriculum in high school. We investigate the modification of probability and statistics curriculum. And we discuss statistics education in university.

The purpose of this study was to investigate the balance reaction characteristics of dementia patients. Under the object of 30 dementia patients, they were divided into moderate group and severe group and examined the correlation among Clinical test of sensory interaction and balance(CTSIB), Berg balance scale(BBS) and Bathel index(BI) according to perceptional function. As a result, CTSIB was no significant difference between severe group and very severe group and BBS was significant difference between severe group ($47.32{\pm}4.80$) and very severe group ($43.09{\pm}4.18$)(p<0.05) and BI was significant difference between severe group ($92.89{\pm}9.33$) and very severe group ($76.82{\pm}6.81$)(p<0.05) and significant correlation among perceptional function, BBS and BI(p<0.05, p<0.01). Therefore, these results should be used the base data of developing rehabilitation program or protection management for dementia patients.

The purposes of this study are to compare practical ability of vocational education high school, investigate effectiveness of recruitment practical examination, and provide basic data that can be helpful to recruit teaching staffs of occupational training institution in the middle stage and strengthen practical guidance capability of teacher through the analysis by variables of teacher's background. To achieve them, concrete capability areas related to practical ability were conceived and differences of new teacher's abilities were compared between area that fulfilled recruitment practical examination and areas that didn't fulfill. The conclusions of this study are as follows. First, practical abilities among specialized subject teachers of vocational education high school were compared by existence of vocational education high school teacher recruitment practical examination. As a result, the average of practical ability of the group who was fulfilled by recruitment practical examination was somewhat high in all of 5 sub-areas for practical ability, but wasn't significant statistically. Second, the differences of practical ability by background variable among specialized subject teacher of vocational education high school were compared. As a result, the group who possesses national technology licence, existence of short-term teaching career, teaching course completion form of open teacher training showed higher average and it showed significant differences statistically.

Purpose : The incidence of obesity has increased in Korea recently. Obesity leads to higher risks of hypertension, hyperlipidemia and insulin resistance. It also leads to risks of respiratory complications. This study was performed to see the effects of obesity on children's pulmonary functions and on developed bronchospasm after exercise loading according to their obesity degrees. Methods : 257 obese children and 150 non-obese children were enrolled. Obese children were divided into 3 groups by the obesity degrees. Pre- and post-exercise loading $FEV_1$(forced expiratory volume at one second), FVC(forced vital capacity) and PEFR(peak expiratory flow rate) were checked in all subjects. The percent predicted values of each parameter was compared according to obesity degrees and the differences between pre-exercise and post-exercise values. Results : The percent predicted value of $FEV_1$, FVC decreased only in the severe obesity group compared with those in the control group. However percent predicted PEFR declined according to obesity degrees. The percent predicted value of $FEV_1$, FVC and PEFR after exercise loading were much lower than those before exercise loading in all groups. Conclusion : As the degree of obesity was higher, the percent predicted value of pulmonary function was lower. And after exercise loading, as the degree of obesity was higher, the reduction of percent predicted value of pulmonary function was larger. Therefore the pulmonary function in obese children must be observed carefully. Further studies on the effects of pulmonary functions in obese children are necessary.

통계는 연역적 사고를 강조하는 수학의 다른 영역과 달리 귀납적 추론과 직관적 사고를 요구한다. 따라서 학교 수업에서 학생들이 실제적인 상황을 모델링 할 수 있도록 하며, 주어진 상황에서 자료를 올바르게 산출하고 분석 할 수 있도록 적절한 지도 방법이 필요하다. 그렇지만 학교 수업은 대다수 알고리즘 연습 위주의 통계 학습-지도로 통계적 사고 교육이 제대로 이루어지지 못하고 있다. 이로 인해 학생들은 형식적인 통계 처리에는 익숙하지만 통계 교육의 궁극적 목적인 변이성과 자료를 현명하게 다루는 능력이 부족하다. 본고에서는 피상적인 기계적 계산위주의 통계교육에서 실제적인 자료를 수집하고, 이를 적절히 가공 처리하여 정보의 가치를 높일 수 있는 통계 지도 방향을 탐색해 보고자 한다.
