지식 기반 사회에서는 논리적인 사고를 통해 외부의 자극에서 새로운 가치를 창조하고 스스로 지식을 형성하는 능력이 필요하다. 그리고 컴퓨터 교육의 목적은 기능의 습득이 아니라 습득한 기능을 유기적으로 이용하여 주어진 문제를 해결하는 논리적 사고력의 향상에 있다. 따라서 논리적 사고력을 기를 수 있는 프로그래밍 교육을 학생들에게 지도하여야 한다. 본 연구에서 논 프로그래밍 입문기 학습자들이 갖는 어려움, 즉 프로그래밍 언어의 단어와 문법 암기 따른 부담을 덜고 프로그래밍 학습이 갖는 논리적 알고리즘 탐구에 집중하고자 기존의 구문 중심 프로그래밍 언어가 아닌 아이콘 기반의 비주얼 프로그래밍 도구를 제시한다. 그리고 기존의 프로그래밍 학습에서 아동들이 추상적으로 해 왔던 프로그래밍 과정을 로봇을 이용하여 구체적이고 실험적인 학습을 하도록 하며 아울러 일반 학급에서 적용할 수 있는 로봇 활용 프로그래밍 교육 프로그램을 구상하였다.

A new speech recognition model, DLSMM(Dynamically Localized Self-organizing Map Model) and its effective training algorithm are proposed in this paper. In DLSMM, temporal and spatial distortions of speech are efficiently normalized by dynamic programming technique and localized self-organizing maps, respectively. Experiments on Korean digits recognition have been carried out. DLSMM has smaller Experiments on Korean digits recognition have been carried out. DLSMM has smaller connections than predictive neural network models, but it has scored a little high recognition rate.

Programming education has the favorable influence on creative logical thinking and problem-solving ability of students. However programming has not been actively taught at the elementary schools. One of the causes is the lack of systematic curriculum. In this paper, we design the curriculum for 'Understanding of Information Processing' in revised ICT educational guidelines using the educational programming language Scratch. We propose curriculum that consists of 4 lessons for 1st and 2nd graders, 5 lessons for 3rd and 4th graders, and 6 lessons for 5th and 6th graders to lesson the cognitive load, and present the instruction plans. Selected group of experts verified our proposed curriculum and instruction plans. According to verification results, we can conclude that almost the area including the targets, educational factors, learning content, amount of learning, instruction plans are appropriate. The curriculum proposed in this paper can help the elementary students learn programming efficiently, and develop their logical thinking, problem-solving ability, creativity, and information processing ability.

This study aimed to analyse the effects of academic self-efficacy of beauty specialized high school students on learning flow and provide basic data needed for their learning instruction. For the purpose, this study surveyed 327 students of beauty specialized high schools located in B metropolitan city and N city. The responses were analysed with the use of the SPSS WIN 21.0. The results are presented as follows: Academic self-efficacy had a significant effect on learning flow and in particular, self-control efficacy and task difficulty preference were important factors. Based on the results above, it is suggested that teachers should present data that is properly converged by techniques and academic knowledge according to levels and steps so that students can have experiences of academic achievements and be encouraged to have higher self-efficiency.

In this research, we designed an educational activities of exploring mathematics programs in a course of mathematics education in teacher's college. We divided future mathematics teachers into 8 groups and suggested 8 mathematics programs to them. Each group explored one mathematics program. We asked to future mathematics teachers exploring some cases that use effectively a mathematics program in the teaching of school mathematics. In the process of an exploring, we designed some activities of teaching and learning. We provided opportunities of long-term exploration, group learning, presentations, exercises, reflections to mathematics teachers. As a result, future mathematics teachers acquired basic knowledge on the usage of mathematics programs in school mathematics textbook. In addition, their capabilities that are needed to explore mathematics programs have been enhanced. Also they had learned the teacher's positive attitude through the activities of teaching and learning.

Nowadays, the trend of early childhood education has focused on finding educational activities to enhance quality of learning with integrative, learner-centered experience by combining each subject and domain. Pre-service early childhood teacher's music drama activity is a sort of integrated education including literature, instrumental music, play, art and movement that are included in the culture and art for preschoolers to help them understand role and value of the art and directly influence personality and creativity and motive to arouse interest in various learning directly. It's expected to see that development of creative teaching plan for the music drama using piano ensemble could support basic research in integrated educational activity in the teacher training course and also, activate the music drama activity. Research findings and suggestion are as follows. First, the music drama activities are systematically and step-by-step implemented according to the audience according to the cooperative learning and creative plans of pre-service early childhood teachers. Second, if understanding characteristics of casts in the music drama and assigning their roles efficiently, it enhances approach of pre-service early childhood teacher music drama activity and activate it. Third, making music in music drama activities can be composed and arranged to suit the musical literacy and level of pre-service early childhood teacher. Fourth, pre-service early childhood teachers could have integrated experience and evaluation efficiently in the short term to use as reference for the teaching plan and data for the music drama.

학생들이 실세계와 수학적 세계사이를 연관시켜 사고하고 해석하는 방법 및 실제 문제를 해결하는 일반적인 전략의 방법론의 하나가 수학적 모델링(Mathematical modelling)이라고 볼 수 있다. 한편, 수학 교수 ${\cdot}$ 학습 과정에서 구체적인 조작 활동을 통하여 학생 스스로가 지식을 ‘구성(construction)’ 할 수 있도록 해 주어야 한다는 구성주의적 사조가 대두되고 있는데, 본 논문에서는 구성주의적 관점에서 수학적 모델링을 통한 수학 교수 ${\cdot}$ 지도를 위한 활용 방안을 한 예시를 통해서 고찰해 보고자 한다.

작도 문제는 역사적으로 아주 오래된 문제 중의 하나일 뿐만 아니라, 현재 우리 나라 기하 교육에 있어 매우 중요한 역할을 하고 있다. 즉, 평면 기하의 중심 정리들 중의 하나인 삼각형의 합동 조건들을 도입하기 위한 기초로 주어진 조건들(세 선분, 두 선분과 이들 사이의 끼인각, 한 선분과 그 양 끝에 놓인 두 각)에 상응하는 삼각형의 작도가 행해진다. 그러나, 현행 수학 교과서나 수학 교수법을 살펴보면, 작도 문제 해결 방법 및 지도에 대한 연구가 미미한 실정이다. 본 연구에서는 작도 문제의 특성, 작도 문제의 해결 방법 및 지도에 관한 접근을 모색할 것이다. 이를 통해, 학습자들이 다양한 탐색 활동 속에서 작도 문제를 탐구할 수 있는 이론적, 실제적 근거를 제시하고, 수학 심화 학습에 작도 문제를 이용할 수 있는 가능성을 제시할 것이다.

The purpose of this study is to investigate the effects of solving multi-strategic mathematics problems on mathematical creativity and attitudes of the 6th grade students. For this study, the researchers conducted a survey of forty nine (26 students in experimental group and 23 students in comparative group) 6th graders of S elementary school in Seoul with 19 lessons. The experimental group solved the multi-strategic mathematics problems after learning mathematics through mathematical strategies, whereas the group of comparative students were taught general mathematics problem solving. The researchers conducted pre- and post- isomorphic mathematical creativity and mathematical attitudes of students. They examined the t-test between the pre- and post- scores of sub-elements of fluency, flexibility and creativity and attitudes of the students by the i-STATistics. The researchers obtained the following conclusions. First, solving multi-strategic mathematics problems has a positive impact on mathematical creativity of the students. After learning solving the multi-strategic mathematics problems, the scores of mathematical creativity of the 6th grade elementary students were increased. Second, learning solving the multi-strategy mathematics problems impact the interest, value, will and efficacy factors in the mathematical attitudes of the students. However, no significant effect was found in the areas of desire for recognition and motivation. The researchers suggested that, by expanding the academic year and the number of people in the study, it is necessary to verify how mathematics learning through multi-strategic mathematics problem-solving affects mathematical creativity and mathematical attitudes, and to verify the effectiveness through long-term research, including qualitative research methods such as in-depth interviews and observations of students' solving problems.
