Children interest themselves in all different toys they see, before beginning to speak. The psychological reasons for children′s interest in toys have been investigated for a long time. Thus many scientists have studied on the question "what is game？", but they have not reached a consensus yet. Such contradiction may be dependent upon different points of view of the researchers about game. Besides, the view of game of a child and an adult is different too. According to an adult game is a rebirth and escape from monotony. For child it is a work. The aim of this study is to make mathematics regarding a mass of abstract concepts for the students of grade 1-3 of primary school in the concrete operations period, more attractive with the help of educational and instructional games, and to contribute to student′s developing. The capability of thinking and producing by changing abstract concepts into concrete ones.

Recently, robot plays an important role in factory automation and its use is rapidly increasing. In paticular, modern industry tends to need the robot to adjust itself swiftly to new workcell. But, robot is to be taught of operator through teaching box in order that it can carry out new tasks. In the process, interruption of the production line is frequent and so much time and expense are required. Computer Graphic Simulator(CGS) provides a useful tool to overcome such a problem. In this paper, CGS consists of teaching mode and execution mode. The 5-axis Rhino robot is modelled in IBM-PC/386 compatible 32-bit personal computer with 80387 co-processor and the simulator performs defined operations on the computer screen.

One of the prerequisites for the improvement of the teaching of mathematics in our country is an improved curriculum-one which takes account of the increasing use of mathematics in science and technology and in other areas of knowledge and at the same time one which reflects recent advances in mathematics itself. In the new curriculum of mathematics, we have found the problems to teach the concept of sets at secondary level. The idea of a set is the most fundamental one in mathematics. So, this thesis contains the studies of the systematic analysis of sets in dealing with the traditional textbook. The scope of the work is limited to the fundamental ideas, and so it merely touches on the topics of the Concpets, Operations, Cardinal Numbers, Application of Logic, one-to-one Correspondence, Probability and so on. It provides only the essentials, definitions, proofs and some example which are already known and understood in their traditional context. It also presents at the appropriate stages the concepts required (illustrated by examples) in a much clearer fashion than classical teaching does. To compete a study of the sets covered in the textbook of each year, greater detail is needed at the appropriate level.

This paper is concerned with the development case of CEA(Course-Embedded Assessment) design tool for engineering education accreditation operations department for CEA system implemented. Each university or programs are already devoting efforts to build research and CEA system for CEA applied to. In order to effectively apply the CEA studies for each program it is required and particularly, the preferred way to build an operating system is considered a difficult situation of the course unit. Therefore, this case study and to propose a method and procedures required to assessment the design basis for curriculum and program assessment unit in terms of the applicability of CEA, proposes a virtual application results. The information proposed in this case study is determined that could be used in the design for the outcomes and assessment of a variety of programs as one of the steps to build the CEA systems.

Simulation is becoming increasingly popular in construction for training, planning and for assessment of projects. There are, however, significant problems inherent in simulating construction which are not common to other simulations. This paper describes the development and use of computer-based game for teaching and learning of some aspects of construction project management. It is concerned with the development of a model used to simulate the construction of a rock- and clay-fill dam. It includes detailed physical modelling of the performance of individual pieces of equipment and their interaction with the ground, the geography of the project and the weather in which the equipment operates. The behaviour of all of the individual pieces of equipment when acting as fleets is also discussed. The paper also describes the modelling issues of non-technical aspects of earthmoving operations. These include environmental impact, safety, quality and risks. The problems of integrating these with the physics-based models of the equipment performance are discussed. The paper also draws on real experience of using the game in classes in three universities in different countries.

The goal of the study is to find the necessary measures to facilitate a desirable Technology and Home Economics curriculum by reflecting the perception and needs of the teachers, principals, educational specialists from the perspective of the curriculum content, professionalism of the teacher, realistic operations of the school, and the administration of the school system. The research was executed through mail surveys to nationwide junior high school technology teachers, home education leachers, principals and to educational specialists. The results obtained from the research are as follows. 1) The integration of Technology and Home Economics was perceived to lessen the burden of students. However the background knowledge and characteristics of the two curriculums are different, and in addition there is a negative perception due to the fact that it is hard to facilitate a class with just one teacher, 2) The issues that were most serious to teachers, principals and education specialists were professionalism of the teacher, qualification of the teachers, and teaching method. 3) In regards to qualifications of the teacher, the teachers requested that teachers should have single qualification in'Technology(or Home Economics)'. The principals were of the similar opinion but the educational professionals wanted dual qualification for both'Technology'and'Home Economics'. As for teaching methodology all 3 groups responded that from the teacher and student perspective the teaching should be divided whereas from the school's perspective the responsibility should be put on a single teacher. 4) Teachers responded that from the perspective of the teacher, parent or student Technology and Home Economics should be separated into taro subjects. On the other hand the principals and educational specialists agreed that from their own perspective Technology and Home Economics should remain an integrated subject and the teaching should be done by one teacher but replied that from the student or parent perspective division of responsibility in teaching would be appropriate.

곱셈은 동수누가, 배, 곱집합을 포함한 여러 가지 의미를 가지고 있고 다양한 상황에서 사용된다. 초등학교에서 곱셈의 이러한 다양한 의미는 교과서에 구체화되어 있으며 지도 방법이나 지도 순서가 다른 개념이나 연산에 비해 매우 안정적으로 정착되어 있다. 그럼에도 불구하고 좀더 보완되고 개선될 여지가 있어 보인다. 이 연구는 곱셈의 여러 개념적 측면들이 어떤 유사점과 차이점이 있는지를 문헌을 통해 고찰해 보고 교과서 분석을 통해 그 지도 방법과 지도 순서가 적절한지를 분석해 보려는 것이다. 연구 결과, 배 개념이 너무 일찍 도입되었으며, 그 이후 곱셈 지도에서 배 개념을 제대로 반영하지 못하였음을 알 수 있었다. 또한 양과 양의 곱셈을 직사각형 넓이 개념을 이용하여 지도할 필요성도 있었다.

We study the paper Zhernovyi and Zhernovyi [Zhernovyi, K.Y. and Y.V. Zhernovyi, "An $M^{\Theta}/G/1/m$ system with two-threshold hysteresis strategy of service intensity switching," Journal of Communications and Electronics, Vol.12, No.2(2012), pp.127-140]. In the paper, authors used the Korolyuk potential method to obtain the stationary queue length distribution. Instead, our note makes an attempt to apply the most frequently used methods : the embedded Markov chain and the supplementary variable method. We derive the queue length distribution at a customer's departure epoch and then at an arbitrary epoch.

This paper addresses the time and motion study on the woodworking in the primary school. Time study by stopwatch is performed for calculating the standard tie of woodworking. The operator process chart is developed for better illustration and teaching methodology. The purpose of this study is to present a good guideline for woman teachers or beginers(teachers), as well as to provide how much time units are adequate for a special woodworking unit of practice art. According to the result, the contribution of this paper is very much and it is very useful for both teachers and students.
