제 7차 교육과정을 비롯하여, 많은 연구들에서 ‘수요자를 중심의 교육’, 즉 학습자의 개별적인 인지적 특성, 수학적 흥미, 재능을 고려하는 수학 교육을 위해 다양한 접근 방법이 모색되고 있다. 1980년대 말 이후부터 러시아에서도 이러한 연구들이 활발하게 진행되고 있다. 본 논문에서는 러시아의 중학교(7-9학년) 수학 교육에서 제시하는 다양한 유형(일반 학생들을 위한 제1유형, 제 2유형, 수학 심화 교육과정)의 교육과정들을 살펴보고, 이를 통해 러시아에서는 교육과정 수준에서 어떤 개별적 접근 방법을 시도하고 있는가를 분석하여, 수학교육의 개별적 접근을 위한 기초 연구를 제공할 것이다.

To improve the elementary student's ability to classify the data and obtain the information from the data through graphics, it is necessary to use the teaching and learning material which encourage the student to study with interest and is adjacent to the student's environment. In this thesis. several materials to satisfy the condition is proposed together with some remarks to direct the teaching. These materials is recommended to use for the maturity learning and teaching in grade 6.

이 논문에서는 지식발견과 데이터 마이닝에 관한 전반적인 소개와 고객이탈에 관한 것이다. 데이터 마이닝이란 과거에 수집된 데이터로부터 반복적인 학습과정을 거쳐 데이터에 내재되어 있는 패턴을 찾아내는 모델링 기법이며 통신서비스시장에서 데이터 마이닝 활용으로 고객이탈방지 모델을 인공신경망을 통해 구축하였다. 통신서비스시장의 경쟁이 심화됨에 따라 통신서비스 제공 업체가 고통으로 겪는 어려움 중의 하나가 고객이탈률이다. 따라서 데이터베이스에서 보다 가치 있는 정보를 찾아내 고객 이탈고객 분류의 적중률에 관하여 논의하였다.

전통적인 수학교육은 간단한 수학적 사실을 이해하고 활용하는 측면에 있어서는 효과적일 수도 있지만, 수학적 개념, 원리, 법칙을 학생 스스로 탐구, 발견하고 창조하는 능력을 기르는 데는 적절하지 않다. 이러한 능력을 기르기 위해서는 학생들 스스로가 관찰, 조작, 분석, 종합하는 활동을 강화할 필요가 있다. 구체적 조작물을 학습도구로 활용하는 경우, 수학 학습에 대한 흥미와 자신감을 길러 주고, 자신의 수준에 맞는 내용을 자기 주도적 학습을 통하여 성취감을 가지게 하며, 학생 스스로 탐구 활동을 활발히 하는데 도움이 된다. 삶의 질이 급격히 향상되는 정보사회에서는 사이버 공간의 등장으로 공간감각 기능의 필요성이 더욱 절실한 바, 현행 수학교과서에서 제공되는 각종 공간 도형들은 3차원 공간에서 이루어지지 않고 평면도형으로 처리함으로써 아동의 도형인지 능력 향상에 큰 효과를 기대하기 어렵다. 이에 본 연구에서는 아동의 인지발달 단계를 고려, 도형인지능력 향상을 위한 선 및 점대칭 관련 동기유발, 선수, 기본, 보충, 심화, 평가, 도움말 관련 프로그램을 개발, 적용한 결과 학습자의 동기가 유발되고, 도형 인지능력 향상에 유의미한 결과를 얻었다.

The purpose of this study was to design and develop a multimedia program for elementary school students' emergent literacy teaching. The program aims at helping students improve their reading ability and enhance their letter decoding ability through drill-and-practice as well as tutorial instructional strategies. To that end, the instructional materials were reorganized so as to provide a basic syllable table and writing examples with standard pronunciation. The multimedia program is composed of three sections: basic literacy teaching, advanced literacy teaching, and evaluation sections. The implications of the study were discussed.

In this paper, we proposed the system that supports underachievers realm decision of Korean language curriculum in the middle school. Learning disability and stagnation should be minimized by using and applying the proposed system. The input layer of the system contains 36 variables, which can be specific items in the Koran language curriculum. The variables are encoded with the specific coding schemes. The number of nodes in the hidden layer was determined through a series of learning stage with best result. We assigned 4 neurons, which correspond to one realm of the curriculum to output layer respectively. We used the multilayer perceptron and the error backpropagation algorithm to develope the system. A total of 2,008 data for training and 380 for testing were used for evaluating the performance.

We consider a Direct Input Output Manufacturing System(DIOMS) which has a munber of machine centers placed along a built-in Automated Storage/Retrieval System(AS/RS). The Storage/Retrieval (S/R) machine handles parts placed on pallets for the operational aspect of DIOMS and determines the optimal operating policy by combining computer simulation and genetic algorithm. The operational problem includes: input sequencing control, dispatching rule of the S/R machine, machine center-based part type selection rule, and storage assignment policy. For each operating policy, several different policies are considered based on the known research results. In this paper, using the computer simulation and genetic algorithm we suggest a method which gives the optimal configuration of operating policies within reasonable computation time.

The purpose of this study is to demonstrate how EFL learners can overcome the limitations of traditional classes and practice communication through the learning activity model. As a research method, it was conducted from March to June 2019 to develop and derive strategies and guidelines through model development, validation, and application. After two validity tests, the model was applied to the experimental group, resulting in an increase of self-direction, engagement, problem-solving, and participation. Moreover the post results showed significant results in all fields, the usefulness of this model was confirmed. However, continuous follow-up research is needed, including the development of software that can easily apply AI related to English learning to classes, and the presentation of convergence activities with more systematic maker education in learning activities.

This study aims to help elementary school teachers increase their knowledge about the changes in the positions of the sun and moon during the day and the first time the moon observation begins in the Earth and Space section of the Earth and the Moon. The survey questions were grouped into four categories, namely, textbook explanation, inquiry activities, achievement of learning goals, and other opinions. The perception of each question differed according to advanced science majors and teaching careers and experiences of this unit. In addition, understanding the diverse views of the participants using descriptive questions was possible. The study recruited 67 teachers working at an elementary school in Gyeonggi-do. The conclusion is as follows. First, the teachers exhibited similar positive and negative perceptions about the description of the textbook on the changes in the positions of the sun and moon during the day. Second, the study found that majority of teachers used alternative methods when guiding students regarding the change in the positions. This trend was not correlated with the sun and the moon, and the study observed no difference in advanced majors and teaching careers and experience of this unit. Third, the majority of teachers responded that they could achieve their learning goals through this learning. However, many teachers complained of various difficulties in guiding students about the lesson, and the majority alternative methods. The results demonstrated the perception of teachers that students can achieve learning goals through alternative methods without direct observation.
