컴퓨터 및 네트워크 기술의 발전은 대학 교육에도 많은 변화를 가져오고 있다. 본 연구에서는 웹/멀티미디어를 통한 통계교육용 통합 소프트웨어 iSTAT을 소개한다. 이 소프트웨어는 통계 초보자들을 위한 교육의 일환으로 전통적인 강의 동영상과 전자책(e-book)을 포함하고 있고, 아울러 복잡한 통계이론의 이해를 돕기 위해 고안된 통계강의 보조시스템 CATS와 통계자료분석 실습용 통계패키지 S-Link, 그리고 배운 이론에 대한 평가 모듈이 있다. 이밖에도 관련 이론에 대한 유용한 웹사이트에 링크를 할 수 있다. 이 종합 시스템을 초보자에게 제공함으로서 통계라는 학문을 보다 쉽고 실제 응용이 가능한 학문으로 보급되기를 기대한다.

수학 통계용 그래픽 계산기와 통계 자료 분석용 소프트웨어를 활용하는 외국과 국내의 통계 교육의 ·추세를 소개한다. 그리고 통계 자료 분석용 소프트웨어인 Statistica의 특징을 요약한 다음 통계학을 효과적으로 교육하기 위하여 Statistica에서 제공되는 Statistica Basic Language로 프로그램한 세 가지 모듈을 제시한다. 프로그램을 입력하는 과정을 간단히 설명한 후 각 모듈을 소개한다. 처음 모듈은 숫자 값으로 표현되는 계량 자료에 대한 단순 통계량들을 구하기 위하여 분석하려는 원시 자료를 Sprea-dsheet에 입력한 다음 Statistica Basic Language로 프로그램한 모듈을 실행시킴으로써 한 번에 입력 자료에 대한 단순 통계량의 결과들을 볼 수 있도록 하였다. 둘째로 1에서 100까지 숫자들을 단순 랜덤 비복원 추출하는 과정을 프로그램한 모듈을 제시하였다. 마지막으로 프로그램한 모듈에서 제시되는 윈도우에 균일 분포에서 단순 랜덤 복원 추출하기 위한 표본의 크기와 샘플링 반복 횟수를 입력하면 표본 평균의 도수분포표와 도수분포도가 작성되어 표본 평균의 분포가 중심극한정리를 따르는가를 확인하였다.

A software, the CATS (Computer Aided Teaching for Statistics), which is specially designed for teaching elementary statistics using the personal computer is developed. This software helps the novice to understand the complicated statistical theories, for example the central limit theorem, which are not easy to teach in classroom. The software is also designed for practicing the elementary statistical techniques using the small amount of data as the other statistical packages.

R is a free software for statistical analysis that provides simple interfaces to other application programs. Many people are trying to learn R, but it is difficult to learn R compared to commercial software such as SPSS or SAS, and it is cumbersome to provide an environment to teach R. Thus, it is essential to provide a new web-based R environment for novice users or for laboratory use. We developedWebER (a web-based R environment) using PHP on the Linux apache server. WebER can be easily used by any R user because we implemented the same functions as the basic Rgui such as editing R program, generating the text, image outputs, errors and warnings. It is also possible for multi-users to access WebER.

최근에 들어서 개인용컴퓨터가 대중화되고 통계처리를 위한 컴퓨터 소프트웨어들을 쉽게 이용할 수 있게 됨에 따라 치의학연구에 있어서도 컴퓨터를 이용한 자료의 통계적 분석이 증가되고 있으며 그 방법도 갈수록 복잡하고 다양해지고 있다. 따라서 오늘날 급속히 발전하는 새로운 치의학지식의 습득을 위하여 치의학잡지에서 증가되고 있는 통계적 분석방법을 이해하고 평가할 수 있는 통계학지식이 요구된다. 이에 저자는 1975년,1980년 그리고 1986년에 발행된 5종류의 치의학잡지에서 보고된 논문에서 통계학방법의 종류와 빈도 그리고 통계학방법의 경향을 조사하여 치의학분야의 통계학교육에 필요한 통계학방법을 제시하고자 하였다.

Software integration becomes very important in these days. Since the 4th industrial revolution has begun and influences its heavy effects on our daily life, software education has been introduced in the 2015 national revised curriculum. The purpose of this study is to verify the effects of a mobile web application for the elementary algorithm class based on STEAM on the problem solving process of elementary school students. To do so, in this study we constructed an algorithm learning contents based on STEAM for new software education and developed a mobile web application for flipped learning to improve their problem solving ability. Further, an experimental group and a controlled group are selected respectively from the 5th grade elementary school students. Then, a new flipped learning class using our mobile materials was applied to the experimental group while a traditional lecture class using the activity papers was applied to the controlled group. Finally the paired samples t-tests were carried out. As a result, we found that there was a statistically significant difference in problem solving process between the two groups. Based on our experimental research and the results of statistical analysis, the mobile web application class based on STEAM turned out to be effective in improving the problem solving ability of elementary school students.

Lately, as the importance of software and the software education has been emphasized, the studies on ways of teaching programming to elementary students have been actively progressed. However, most of undergraduates as prospective elementary teachers who will be in charge of teaching programming at the elementary schools have a lack of interest in programming education as well as of the understanding of basic programming principles. Therefore, this study investigated how programming education using hands-on robot and scratch affected learning motivation and academic achievement of preliminary teachers. The comparison of results of two programming educations shows that the programming education using hands-on robot revealed statistically significant difference in learning motivation and academic achievement.

Scratch is Educational Programming Language, and it has been widely used in Elementary school SW Education. Many studies show that Scratch education is helpful for students' computational thinking and problem solving. However, the lower grade students use scratch less than the higher grade students, and the higher grade students have difficulty in understanding basic programming principles such as sequence, repetition, and condition. Therefore, in this study, we developed Scratch electronic blocks and programming education curriculum. We had classes for 2nd grade and 6th grade students, and it was confirmed that the score of 2nd grade students' interest about programming increased from 3.28 to 3.58 and 6th grade students' interest increased from 3.41 to 4.09. As a result of the programming basic principles understanding assessment, 84% of the 2nd grade students solved more than 7 of the 9 questions and 62% of the 6th grade students solved more than 7 of the 9 questions.
