This study is necessary for the stable settlement of the 2022 revised mathematics curriculum 'data and possibility' area. This study was conducted centering on literature analysis. The purpose of this study is to realize statistics education in line with the 2022 revised mathematics curriculum. This purpose was achieved by examining the statistics learning contents of the 2022 revised curriculum, analyzing Chinese mathematics curriculum, and analyzing Chinese mathematics textbooks. In this study, the following studies were conducted. First, five elements were extracted through the analysis of the 'statistics and probability' area of the Chinese mathematics curriculum. The extracted elements are the 4th grade goals, synthesis and practice content areas, achievement standards for statistics and probability (6), (9), and (11). Second, examples presented in Chinese mathematics textbooks and Chinese curriculum appendices related to the extracted elements were analyzed. Regarding the 4th grade goal, the statistical problem-solving process of the 7th grade 2nd semester mathematics textbook was analyzed. Regarding the synthesis and practice content area, the data analysis unit of the 8th grade 2nd semester mathematics textbook was analyzed. In relation to the achievement standard (6), Example 85 of the curriculum appendix was analyzed, in relation to the achievement standard (9), Example 86 was analyzed, and in relation to the achievement standard (11), Example 87 was analyzed. Third, based on the analysis results, implications for the development of new curriculum and 'textbook development, teaching and learning methods' according to the 2022 revised middle school mathematics curriculum were derived. Through the results of this study, we expect the successful realization of the 2022 revised middle school mathematics and curriculum statistics education.

This study compared and analyzed Korean, American, Singaporean, and Japanese middle school mathematics curriculum standards and the learning contents in statistics. Through a comparative analysis of the curriculums of these four countries, I found several overall features and differences between the curriculums. First, all four countries emphasized statistical education in a real-life context. Second, all four countries emphasized the use of technological tools. Third, there is a middle school grade in which only Korea does not deal with statistical domains. Fourth, the statistical areas of the United States, Singapore, and Japan focused on identifying trends or variability in data distribution. Fifth, I have found some contents that only Korea does not deal with. Based on this, the following recommendations were developed for the development of the next curriculum and new textbooks in Korea. First, the statistics curriculum should be changed from one that focuses on understanding statistical concepts to one that focuses on statistical activity that utilizes these concepts. Second, in terms of middle school statistical curriculum contents, the addition of interquartile range (IQR) and box plots as learning contents should be considered. IQR and box plots are simple and practical techniques for the comparison of multiple sets of data that can be easily learned and drawn by middle school level students and applied to real-life-related statistical data to expand statistical literacy. Through this study, it is suggested that IQR and box plots need to be included in the statistical curriculum of middle schools in Korea.

According to prior research studies, comparison of two data sets promote informal and formal statistical reasoning, which may mediate descriptive and inferential statistics. However, there has been relatively little attention given to the mediation of both descriptive and inferential statistics. We attempted to identify which statistical concepts or factors students used and how they applied concepts or factors to make decisions when they compared data sets. We also investigated the characteristics and changes of the view of concepts and factors. As a result, we identified that students paid attention to data value, center, spread, and sample, which are important factors of inferential statistics. Students' understanding of each factors were sometimes appropriate for inferential statistics, but sometimes not. From the results, we suggest instructional ideas for a task which can connect descriptive and inferential statistics.

중학교 '환경'교과교육을 실시하고 있는 학생과 실시하고 있지 않은 학생을 환경에 대한 지식, 태도, 실천의 세 가지 측면에서 비교한 결과를 요약하면 다음과 같다. 환경에 관한 지식도와 태도면에는 실시군이 비실시군보다 평균점수가 높았으며 이것은 통계학적으로도 유의한 차이를 보였다(p<0.05). 한편 두 집단의 환경에 관한 실천도의 경우 실시군과 비실시군간에 차이를 보이지 않았다. 환경교과교육 실시군과 비실시군 간의 지식도를 영역별로 찾아본 결과, 재활용 및 분리수거와 환경보전 요인에서 실시군이 평균점수가 높았으며 통계학적으로 유의한 차이를 보였다. 환경에 관한 태도의 경우 환경오염과 재활용 및 분리수거 요인에서 실시군이 비실시군보다 평균점수가 높았으며 통계학적으로 유의한 차이를 보였다. 환경에 관한 실천도의 경우 영역별로 두 군을 비교한 결과, 모든 요인의 평균 차이가 통계적으로 유의하지 않는 결과를 보였다.

The purpose of this study was to analysis the relation and behavior of oral health promotion. Also, This study was to provide educational data of oral health. The obtained were analysed by SPSS program 12.0. The findings were as below: 1. Dental visit for prevention Y/N(%) was higher 50 years than 20 years(p < .001). Oral hygiene devices Y/N(%) for oral hygiene showed University graduates higher than Middle school graduates respectively(p < .05). 2. The knowledge of oral health was higher High school graduates than Middle school graduates respectively(p < .05). The rate of brushing teeth 3~5 times per day was higher females than males(p < .01) and better College graduates than Middle school graduates respectively(p < .001). 3. Oral health conditions of respondents were better 20years and 30years than 50years respectively(p < .001). Self-evaluation of Oral health sensitive was better College graduates than Middle school graduates respectively(p < .05). 4. Correlation between of Tooth brushing Frequency per Day by Oral health knowledge, dental clinic Visit, Extraction number had an effect on the significant dental clinic visit for prevention and the knowledge of Oral health had even a positive effect relationship(r = .233, p = .001). The knowledge of Oral health and the frequency of tooth brushing had even a positive effect relationship(r = .161, p = .05). The frequency of tooth brushing and the number of extraction of teeth had a negative effect relationship(r = -.145, p = .05).

The subjects of this study were 10th grade students and 10 non-disabled students. For statistical programs, data were processed using SPSS Windows 25.0, and the statistical method used in the study was to calculate the mean and standard deviation of physical fitness factors and body mass index to determine the health and obesity of students with intellectual disabilities and non-disabled students. In addition, this study was conducted using the independent sample t-test to identify the differences in health fitness and obesity between intellectually and non-disabled students. The statistical significance level of the study was set at p <.05, and the results of the study showed that there were statistically significant differences in cardiopulmonary endurance, flexibility, muscle strength, muscle endurance, and responsiveness between middle and high school students with intellectual disabilities and non-disabled students. In the case of obesity, intellectually and non-disabled students were significantly different.
