A common geoboard puzzel serves as the point of departure for an investigation that lends itself to whole-group discussion with a class of prospective secondary school teachers. Students are provided with opportunities to devise and carry out problem-solving strategies (called 'heuristics' by Polya); exploit inerrelationships among geometry, arithmetic and algebra; formulate generalizations and conjectures; plan and execute an computational project; construct mathematical arguments to establish theorems; and find counter-examples to dispose of a false conjecture. In recent tears, Eugene F. Krause wrote two papers having the same title except for the numeral In that papers he arrives at an theorem about the sizes of squares with lattice point vertices in the coordinate plane, In this paper we follow a different path genearlization to coordinate 3-space

In this study, we have investigated the meaning and mechanism of the 'construction' in the operational constructivism and the social constructivism. According to Piaget, a mathematical concept is the operational sch me, which is constructed through the reflective abstraction from a general coordination of activities and operations. The process of the reflective abstraction consists of 'reflechissement'and 'reflexion'. The reflechissement starting from 'intriorisation' concludes with 'thematisation', and the reflexion consists in the 'equilibration' of the result of reflechissement. The 'construction' in the social constructivism includes two process. One is the process from the individual, subjective knowledge of mathematics to the social, objective knowledge of mathematics, and the other is vice versa. The emphases is placed on the 'social interaction' and the 'representation' in this two processes. In this context, if we want to apply the social constructivism, we should clarify the meaning of 'society', and consider the difference between the society of mathematicians and the society of students.

This paper is composed of computer programs and practical examples for the education of mathematics. The Animation package in the Mathematica standard packages is the Graphics Animation. Animations are the ways which produce a sequence of different pictures by rapid succession. The command Animate has a number of options such as Animate, SpinShow and ShowAnimation. Mathematica is available for a large variety of practical education of mathematics. The method in this report are familiar with the general principles of operating the computer in Mathematica 3.0. In this paper there a set of useful examples of mathematical education and we discusses some of the advanced technique for the Input-Output systems.

Global environment is getting deteriorated at an alarming rate. Eco-school could be one of the effective solutions to project our environment and a good sample of architecture to economize in total energies, resources and greenhouse gases. In case of our country, the study of eco-school planning is not sufficient compared with other countries, so this paper would be a good study on the indoor environment of the classroom by surveying their opinions and ideas from the group of users in school facility. The result of this study shows that the proper installation of building equipment and nature ventilation system is necessary to provide delightful environment for the students and to save the energy. To ensure that we have adequate saving and protection it is necessary to change the existing appraisal standard.

The purpose of this study is in providing a systematic method for school building color scheme. This study analyzed the cases of color uses in domestic and foreign school buildings. The results from this study tells that the colors in school buildings should take into account the environmental, psychological and functional elements at the same time to effectively function as environmental color, effect color and induction color.

Area Offices of Education in Korea assign and execute government budget based on the evaluation of school buildings' safety rating and degree of their deterioration. However, it is never easy to estimate the most appropriate investment amount for old buildings under consideration of their service lives and residual values together. A model of estimating optimum investment cost for obsolete school building is developed taking its life cycle cost into account. The model is also applied to six old buildings in five different schools and found that some of the facilities hardly needed further investment and were better to be rebuilt. The study results will be a great beneficial for officers to make right decision on maintaining obsolete school buildings and to maximize tax payers' money.

The deaths caused by industrial accidents during the construction of the mortality rate is considerably higher than in other industries. To prevent such a disaster workers and to minimize unsafe behavior measures to be drawn, and construction companies recently to stimulate the emotions of the workers to participate in voluntary activities are safe. In this study, the construction workers can stimulate emotions and activities on the environment by examining the preferences of the workers on-site management will want to take advantage. This study revealed that the construction workers prefer the incentive most and then working environment.

Under the WTO, UIA asks professional degree programs such as B.Arch program, practical experience, and an examination to meet the international requirements. In this context, we are started professional degree programs. Following the foundation of KAAB, Korean architectural education sectors have made substantial changes throughout the nation. There was lots of discussions about education system, however, we are lack of discussing about internship program in Korea. Therefore, this research was intended to review the professional practice program in other countries for the purpose of propose our education program. The specific content deals with various issues, like CPD and foreign architect legislations, and the recent korean legislation reform of 'Architect Law' centered upon Professional Training System. The aim is to identify the examples of forms and contents regarding the execution of new Professional Training System in current conditions.

This study aims to find out the feasibility and effectiveness of mathematical games as a way to provide primary pre-service teachers with doing mathematics. The game had induced the active participation of elementary pre-service teachers. Through transforming the game, the teachers have been able to experience of mathematical problem posing and generating mathematical representation. Based on this, we discuss the role of mathematical games as a method of pre-service teacher education.

This study aims to design an exemplification task to facilitate the students' creative thinking, and to investigate mathematical creativity which emerges from exemplification. In particular, we aim to identify the ways to design exemplification tasks which encourage creative thinking, and characterize mathematical creativity fostered by exemplification. The findings showed that the students' creative thinking related to fluency, flexibility, elaboration, and originality emerged through exemplification.
