The objective of this research is to compare the teacher education system in countries that have reformed, or are in the process of reforming, their informatics education by reflecting ongoing social changes and developments in IT. The teacher education systems in Finland, Germany, Japan, the UK and US were compared. As a result of the study it was found that (1) the results did not differ according to the teacher education institution, (2) there was a focus on a minor subject, and (3) there were various routes for teacher training. The systems for special graduate schools were found to be developed, probation period after graduation was more than one year, and license renewal systems were being enforced. Based on these results, it was proposed that (1) more teachers be recruited to attend graduate schools and (2) that software training be given to all teachers as a minor. Finally, a license renewal system for revaluating teachers' qualifications was also proposed. This research is meaningful in that it compared the teacher training system in Korea with five major developed countries.

The ability to use information technology has become increasingly important as technological advances continue to sweep through the computing world, and education for improving computational thinking has become globally instituted. In South Korea, informatics subjects have been modified in the 2015 curriculum and are now compulsory in primary and secondary education. However, despite substantial financial investment and numerous studies promoting informatics education, there continues to be a serious lack of pre-service teachers capable of teaching computational thinking. This study investigated pre-service teacher programming education using App Inventor, their perceptions of App Inventor, and how use of the program affected teacher problem-solving abilities and self-efficacy. In the pre-test, the control group and experimental group showed no statistically significant difference; however, the post-test revealed that the two groups showed statistically significant differences in problem-solving skills and self-efficacy. The participants initially showed interest in using App Inventor; however, after practice-teaching and project-based learning, the participants demonstrated a growing negativity toward the program when they made errors and the functional limits of App Inventor became apparent. Although most participants stated that they would not use App Inventor in their classes, the positive statistically significant differences in problem-solving skills and self-efficacy indicate that this study could be utilized as a basis for building a teaching-learning program using App Inventor and creating an educational plan for teaching computational thinking.

This paper has analyzed contents of copyright education in Informatics textbook in middle school curriculum and has proposed ways to enhance copyright education. In this paper, we have analyzed Informatics curriculum, authorized textbook, and teacher's guide book for middle school revised in 2007 and have extracted contents and systems of copyright education in Informatics course. We examined studies on the copyright education and analyzed on the basis of interest, understanding, usage, and practice of copyright. As a result, copyright education has turned out to be focused on 2nd level of information society and information technology. We found that copyright education was necessary both directly and indirectly in various parts and levels in that it is an optional subjects. This paper suggests the possibility of copyright education in Informatics curriculum for middle school and the copyright education is expected to be reinforced.

본 논문에서는 예비 정보교사들이 학교 현장의 문제점을 고민하고, 그에 대한 아이디어를 학생 주도적으로 고안해나갈 수 있도록 하는 캡스톤 디자인 강의의 개발에 대해 논한다. 본 논문은 기초연구로서 캡스톤 디자인 교과목의 개발 과정 및 단계를 설계하고, 교과목 개발의 바탕이 되는 정보교사의 역량에 대하여 고찰하였다. 후속 연구로서 본 논문에서 선정한 정보교사의 역량을 바탕으로 학습자의 요구분석을 실시하고 실제 캡스톤 디자인 교과목을 개발하여 예비 정보교사들을 대상으로 캡스톤 디자인 강의를 실시할 것이다.

2015개정 교육과정은 소프트웨어 교육을 강조하고 있으며, 초등에서도 정보 교육이 실시될 예정이다. 이에 따라 초등 교사의 정보 교수 역량 정도를 살펴보거나 연수 후 연수 효과를 살펴보기 위한 검사도구가 필요한 시점이다. 따라서 본 논문에서는 기 개발된 초등교사의 정보 교수 역량을 측정할 수 있는 정보 교수효능감 검사도구 개정의 네 가지 방향성을 제시하였다.

본 연구에서는 비 정보과 교사들의 효과적인 SW 교육 교수효능감 함양을 위하여 팀 프로젝트 기반 융합 교육 프로그램을 개발하였다. 개발된 교육 내용은 융합교육 및 팀 프로젝트에 대한 이해를 바탕으로 수학, 과학, 정보 등이 융합된 다양한 프로젝트를 실습한 뒤, 직접 문제 해결을 위한 프로젝트의 설계 및 개발과 발표, 동료 평가 및 피드백의 과정으로 구성되어 있다. 이는 10주간 비 정보과 교사들에게 처치되었고, 사전-사후 t-검정 결과, 통계적으로 유의한 향상을 나타내었다. 하지만 본 연구의 실험은 단일집단을 대상으로 하였기 때문에 추후 통제집단과의 비교를 통하여 향상에 대한 통계적 비교가 필요로 된다.

2015 개정 교육과정에서는 미래 사회의 인재를 육성하기 위해 중학교에 정보 교과를 필수화하였다. 이를 지도할 정보·컴퓨터 교사를 확보하기 위해 비 정보과 교사를 대상으로 부전공연수를 실시하여 정보 교육을 할 수 있는 자격을 부여하고 있다. 이들은 일반 학습자와 다르게 교육학적 지식과 역량은 높으나, 내용 지식은 컴퓨터과학의 초보자 수준이다. 이러한 학습자의 특성을 고려하여 마이크로비트를 활용한 연수를 12차시 동안 진행하였고, 이는 비 정보과 교사의 프로그래밍 자아효능감에 긍정적인 영향을 준다는 것을 확인할 수 있었다. 그러나 본 연구는 단일집단에게 실험을 실시하였으므로 그 효과를 일반화하는 데 한계가 있다. 따라서 후속 연구에서는 비교 집단을 설정하는 실험 설계로 교육 효과를 검증할 필요가 있다.

In this paper we use iterative dynamic programming in the discrete case to solve a wide range of the nonlinear equations systems. First, by defining an error function, we transform the problem to an optimal control problem in discrete case. In using iterative dynamic programming to solve optimal control problems up to now, we have broken up the problem into a number of stages and assumed that the performance index could always be expressed explicitly in terms of the state variables at the last stage. This provided a scheme where we could proceed backwards in a systematic way, carrying out optimization at each stage. Suppose that the performance index can not be expressed in terms of the variables at the last stage only. In other words, suppose the performance index is also a function of controls and variables at the other stages. Then we have a nonseparable optimal control problem. Furthermore, we obtain the path from the initial point up to the approximate solution.

In this paper, we have considered an investigation on goodness of fit tests based on divergence measures. In the case of categorical data, under certain regularity conditions, we obtained asymptotic distribution of these tests. Also, we have proposed a modified test that improves the rate of convergence. In continuous case, we used our modified entropy estimator [10], for Kullback-Leibler information estimation. A comparative study based on simulation results is discussed also.
