The law of large numbers, central limit theorem, and connection among binomial distribution, normal distribution, and statistical estimation require dynamics of continuous visualization for students' better understanding of the concepts. During this visualization process, the differences and similarities between statistical probability and mathematical probability that students should observe need to be provided with the intermediate steps in the converging process. We propose a visualization method that can integrate intermediate processes and results through Excel. In this process, students' experiences with dynamic visualization help them to perceive that the results are continuously changed and extracted from multiple situations. Considering modeling as a key process, we developed a classroom exercise using Excel to estimate the population mean and standard deviation by using a sample mean computed from a collection of data out of the population through sampling.

2001년 교육부, 초 중등학교 정보 통신 기술 교육 운영지침 해설서에 따르면 교과에서의 스프레드시트의 활용에 대해 수학 교과 이외에 과학, 실과, 도덕, 체육, 사회에서 활용 가능한 프로그램으로 제시하고 있다. 그러나, 기존의 스프레드시트는 아동들이 사용하기에는 다소 불편하다. 아동들은 복잡한 함수식을 어려워하며, 복잡한 메뉴들이 교과학습에 활용될 때는 학습목표달성에 오히려 방해가 된다. 또한 구이 측면에서 볼 때 아동들이 직관적으로 보고 느낀 대로 프로그램을 활용하기에는 어려움이 있다. 본 논문에서는 초등학생의 확률 및 통계부분 지원을 위한 스프레드시트를 연구하였다.

In this study, we gave 132 high school students fifteen probabilities and nine statistics problems of the Korean College Scholastic Aptitude Test and then analyzed their answer using the classical test theory and the item response theory. Using the classical test theory (the Testian 1.0) we get the item reliability ($0.730 \sim 0.765$), and using the item response theory (the Bayesian 1.0) we get the item difficulty ( $-2.32\sim0.83$ ) and discrimination ( $0.55\sim 2.71$). From results, we find out what and why students could not understand well.

Purpose: This study aimed to identify the factors affecting the chemotherapy medication errors made by new nurses and to use the results as basic data for the development of a chemotherapy medication nursing education program for new nurses. Methods: This cross-sectional study was conducted with 189 new nurses working at a general hospital and a tertiary general hospital in Korea. The data collection period was from January 11 to February 7, 2021. The data collected during this study were analyzed using the IBM SPSS statistics version 25.0 program. Data analysis included descriptive statistics, independent t-test, ANOVA, and logistic regression analysis. Results: One factor influencing chemotherapy medication errors was new nurses' educational needs (odds ratio=.18, p=.005). As educational needs increased, the probability of making errors in medication was reduced by .18. Conclusion: It is necessary to develop a chemotherapy medication education program tailored to the educational needs of new nurses by considering the education period, method, and content, with a focus on the content with high demand from new nurses.

Background: Parental attention is crucial for preventing childhood oral diseases. Mothers play a significant role in maintaining their families' oral health, and their educational level influences their children's oral health behaviors. This study investigates the impact of mothers' educational levels on adult oral health behaviors using data from a national survey. Methods: This study employed a cross-sectional analysis of secondary data. The data used were obtained from the 8th Korea National Health and Nutrition Examination Survey. Descriptive statistics were calculated to identify participant characteristics. Next, t-tests and one-way analysis of variance were conducted to examine the effects of the explanatory variables on the distribution of the dependent variable. Finally, logistic regression analysis was used to investigate the influence of the explanatory variable on the dependent variable, using "no education" as the reference value, and calculate the odds ratios. Results: Children of mothers with a college education or higher had a 1.13 times higher likelihood of receiving oral examinations than those whose mothers had no education. Children whose mothers graduated from college or higher had a 2.23 times higher probability of receiving preventative dental treatment than those whose mothers had no education. Children whose mothers graduated from college or higher had a 1.92 times higher probability of receiving scaling than those whose mothers had no education. Children whose mothers graduated from high school had a 1.35 times higher probability of receiving scaling than those whose mothers had no education. Conclusion: Developing oral health programs is important for low-educated and low-income parents to change theirs and their children's oral health behaviors/attitudes. This will help reduce oral health disparities among adults raised by parents of higher and lower socioeconomic statuses. Therefore, a comprehensive approach is essential for adults to maintain good oral health, regardless of variations in their parental educational levels during childhood.

The main purpose of this paper is to develope elementary mathematics teaching-learning programs for pre-service elementary teachers. The elementary mathematics education program developed in this work is divided into two parts: One is the theory, the other is the practice. The theory deals with the foundations of mathematics, the objectives of mathematics education, the history of mathematics education in Korea, the psychology of mathematics learning, the theories of mathematics teaching and learning, and the methods of assessment. With respect to the practice, this study examines the background knowledge and activities of numbers and their operation, geometry, measurement, statistics and probability, pattern and function.

본 연구는 학생들의 수학논술 교수 학습과정에서 나타나는 수학적 과정과 관련된 여러가지 특징들을 조사하고 수학 학습에서 학생 개개인에게 나타나는 긍정적인 변화를 분석하여, 수학논술이 '수학적 과정'을 학습하도록 하는 교수 학습활동의 대안이 될 수 있음을 확인하는데 목적이 있다. 이를 위해, 수학논술 과제를 개정 수학과 교육과정의 확률과 통계 영역 분류에 따라 재구성 하였고, 고등학교 3학년 학생 8명을 대상으로 하여 수업을 실시한 후 수학적 과정 요소를 중심으로 분석하였다. 그 결과 수학적 문제해결, 추론, 의사소통과 관련한 다양한 특징들이 나타났으며, 특히 수학논술 과제가 학생들의 일반적으로 나타날 수 있는 수학적 과정과 관련한 특징뿐만 아니라 보다 발생가능성이 낮은 특징들 또한 나타나도록 하는데 도움이 됨을 확인할 수 있었다.

현재 우리나라의 수학과 교육과정의 체제는 '가. 성격' '나. 목표', '다. 내용', '라. 교수 학습 방법', '라. 평가'로 구성되어 있다. 학교에서 구체적으로 학습해야 할 수학 성취기준은 '다. 내용'에 학년별로 제시되어 있다. '다. 내용'은 초등학교의 경우 수와 연산, 도형, 측정, 확률과 통계, 규칙성과 문제해결의 5개 하위 영역으로 구성되어 있으며, 중학교와 고등학교의 경우에는 수와 연산, 문자와 식, 함수, 확률과 통계, 기하의 5개 하위 영역으로 구성되어 있다. 이와 같은 하위 영역들은 초등학교의 규칙성과 문제해결 영역에서의 문제해결을 제외하고는 모두 수학적 주제들을 다루는 내용 영역이라고 할 수 있다. 이 글에서는 수학과 교육과정의 '다. 내용'에 5개의 내용 영역 이외에 '수학적 과정'이라는 하위 영역을 신설하여 추가하는 방안에 대해 살펴보고자 한다.

The purpose of this study is to find research areas that were less represented by the researchers of mathematics textbooks and to provide feedback for the research and development of mathematics curriculum and textbooks. In order to complete this study, we analyzed comparative studies of mathematics textbooks published in Korean. This study analyzed 107 comparative studies published until recently based on following aspects: countries studied (North Korea, U.S.A., and Japan), Math curriculum studied (6th and 7th mathematics curriculum), and Math contents studied (probability and statistics) and etc. The result of this study suggests that the content area of creative problem solving was particularly less represented by the studies published and require more concern from the mathematics education researchers
