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.

We introduce the category IRel (H) consisting of intuitionistic fuzzy relational spaces on sets and we study structures of the category IRel (H) in the viewpoint of the topological universe introduced by L.D.Nel. Thus we show that IRel (H) satisfies all the conditions of a topological universe over Set except the terminal separator property and IRel (H) is cartesian closed over Set.

We took note of the fact that there were not many studies on improvement of mathematics learning in the field of statistics for the minority students from the families who belonged to the Low-SES. This study was to help them understand the concepts and principles of mathematics, motivate them for mathematics learning, and have them feel familiar with it. The subjects were 12 students from the low-SES families among the sophomores of 00 High School in Gyeonggi-do. Although it could not be achieved effectively in the short-term of learning for the slow learners, their understanding of basic concepts and confidence, interests and concerns in statistical learning were remarkably changed, compared to their work in the beginning period. Our discourse classes using various topics and examples were well perceived by the students whose performance was improved up to the 3rd thinking level of Mooney's framework. Also, a meaningful instructional model for slow learners(IMSL) was found through the discourse.

This research aims to analyse implementation effects of the Real mathematics Education(RME) in the high school probability and statistics For this aim, two research questions are estabilished as fellows. (1) Is there any improvement of mathematical achievement in the class by RME's lecture than in the class by the mathematics text's lecture ? (2) Is there any improvement of mathematisation level in the class by RME's lecture than in the class by the mathematics text's lecture ? Before answering the above research questions, RME.`s lecture notes and ordinary lecture notes are developed based on the learning principles of the RME and mathematics textbook respectively. Two classes are randomly chosen from a high school located at midium size city and assigned as the experimental group and the control group respectively. The 20 hours of the RME's lecture notes is administerd to the experimental group and the 20 hours of the odinary lecture notes is administerd to the control group. It is shown that the class by RME's lecture is more effective in both of the mathematical achievement and the mathematisation activity than the class by the ordinary lecture. Hence, it is urged from the result of this research that RME's context will be developed and the RME's lecture will be implemented in the other field of high school mathematics.

Purpose: The purpose of this study is to evaluate effects of a health education program based on social cognitive theory on university students with risk factors for metabolic syndrome. Methods: A nonequivalent control group pretest-posttest design was used. Participants were 88 students who had at least 2 risk factors for Metabolic Syndrome (47 students for the experimental and 41 for the control group). The health education program consisted of thirteen sessions. Knowledge regarding smoking and alcohol drinking, self-efficacy and self-esteem were evaluated. t-test, $x^2$-test, Fisher's exact test, and paired t-test were conducted to analyze the data. SPSS/WIN 19.0 Statistics program was used. Results: There was a statistically significant increase in self-efficacy in the experimental group compared to the control group. No significant changes in knowledge and self-esteem were found. Conclusion: The results suggest that the health education program for university students was partially effective. Further work is required to develop more effective health education programs.

This paper presents a smartphone application for the clinical practice education conducted in hospitals, with an aim to evaluate its effectiveness. A nonequivalent control group posttest design was used, which included a total of 100 nursing of school students who conducted their clinical practice. They were divided into one control and one experimental group (50 students each). The control group was directly trained in the clinical practice orientation, and the experimental group was a group who self-learned the clinical practice orientation using a smartphone application. Research data were collected between March 5 and April 27, 2019. They were analyzed with descriptive statistics and independent t-test, using the SPSS Statistics Version 24. The smartphone application customized for the clinical practice education was implemented through the following four phases: analysis, design, development, and evaluation. The developed application was registered in Google Play (for Android apps) and Apple Store, and related information was provided, making it available for download. The study showed that the satisfaction with and self-confidence in learning differed significantly between the groups. However, technology acceptance and knowledge acquired through practice showed no statistically significant difference. The research results serve as basic data for applying smartphone applications as an educational method that can replace traditional modes of education, serving as a significant indicator of the education delivery method diversification.

이 연구의 목적은 통계청에서 실시한 2011년도 사교육비 조사의 자료를 이용하여 학생의 학업성취도, 가정의 사회경제적 지위, 보완 사교육비, 일반 사교육비 사이의 효과를 구조방정식 모형을 이용하여 분석하고, 이러한 구조적 효과가 성, 지역, 학교급 집단 별로 유의한 차이가 있는지 다중집단 구조방정식을 활용하여 확인하는 것이다. 연구 모형의 분석 결과를 바탕으로, 사회경제적 지위가 높을수록 사교육에 대한 지출이 커지는 경향이 있지만 학업성취도에는 영향을 미치지 않는다는 결론을 얻을 수 있다. 또한 성, 지역, 학교 집단 모두 학생의 학업성취도, 부모의 사회경제적 지위, 사교육비의 집단 간 구조적 효과의 차이가 있다는 결론을 얻을 수 있다. 이 연구를 통해 우리나라 교육 현상 중에서 학업에 대한 열의가 사교육으로 많이 집중되어 나타나는 사교육 문제에 있어 학생의 학업성취도, 부모의 사회경제적 지위와 사교육비가 연관되어 있을 것이라는 사회적 통념을 2011년 사교육비 조사자료를 이용하여 판단할 수 있을 것이라고 기대한다.

본 연구는 D대학 아동영어교육학과 재학생 88명을 대상으로 자아존중감, 전공만족도, 진로정체감 및 대학생 활적응과의 관계를 조사하였으며, 수집된 자료는 IBM SPSS Statistics 22를 이용하여 신뢰도분석, 요인분석, 빈도분석, 기술통계량, t-검정과 분산분석, 상관분석, 다중회귀분석을 실시하였다. 자아존중감, 진로정체감, 전공만족도 및 대학생활 적응 간에는 모두 유의한 정적인 상관관계를 보였으며, 대학생활과 가장 상관관계가 높은 것은 자아존중감, 전공만족도, 진로정체감 순이었다. 대학생활적응에 영향을 미치는 것은 자아존중감(${\beta}=.664$, p=.000)과 전공만족도(${\beta}=.349$, p=.000)이었다. 아동영어교육학과 재학생의 대학생활 적응력을 높이기 위해서는 자아존중감, 전공만족도를 증진하기 위한 아동영어교육학과 특성에 맞는 체계적이고 구체적인 프로그램이 필요할 것으로 사료된다.

In this paper, we investigate a hybrid algorithm for finding zeros of the sum of maximal monotone operators and Lipschitz continuous monotone operators which is also a common fixed point problem for finite family of relatively quasi-nonexpansive mappings and split feasibility problem in uniformly convex real Banach spaces which are also uniformly smooth. The iterative algorithm employed in this paper is design in such a way that it does not require prior knowledge of operator norm. We prove a strong convergence result for approximating the solutions of the aforementioned problems and give applications of our main result to minimization problem and convexly constrained linear inverse problem.
