Semiotic studies in mathematical education have been based on Saussure, Peirce, and Frege and many prior researches have explored the concepts in a perspective of semiotics. However, the relationship among semiotical elements and the formation and the evolution of a conception are still ambiguous and veiled in many aspects. This thesis is intended to show how a conception was formed and evolved by expression, which is an element of semiotics. In this process, I sought to partially illuminate the relationship among expressions, concepts, and objects.

This article proposes to examine how the study of failure differs from other technical subjects, and how to turn failure experiences to one's advantage. The authors surveyed the properties of failures in PBL (Project Based Learning) and also examined students' interest and understanding of failure, after introducing failure examples. To investigate how students communicate failure experiences to third parties, reports of the failure experience in PBL were evaluated. From above mentioned surveys, we get the following results. The typical causes of failure in educational institutions are lack of skill in manufacturing and inadequate planning, which conversely are minor causes of failure in the industry. A knowledge database on failure, employed commonly in industry, is not effective in PBL, because projects in educational institutes are usually changed every year. Case studies in failure can be approached from many points of view including causes, processes, effects and safety measures. While teachers should emphasize the notable points in the failure examples in introducing examples of specific topics in machine design, teachers should explain the multiple aspects in the failure examples to educate students about the complexity of actual accidents.

The purpose of this study is to investigate various mathematics education improvement or reform movements of Western Europe countries (United Kingdom, Germany, etc.) and the United States of America, to see the effects of those movements on Korean mathematics education circle, and to find a direction of Korean mathematics curriculum design. The third Korean mathematics curriculum was most affected by the new mathematics movement of the United States of America. This movement was emphasizing abstract structure, logical rigorousness and discovery learning of mathematics, which was fired from late fifties. Korean mathematics education circle imported the new mathematics early seventies from USA, but serious problems had been found at that time in USA. This study has pointed out that new math oriented Korean mathematics curriculum was not proper and the new mathematics itself was disastrous for most Korean students' learning. The study also points out that they hurried too much introducing the new mathematics and publishing new mathematics oriented textbooks but they had not sufficient teacher training programs. In our future mathematics curriculum reform, we have to remember such a historical lesson.

In recent years assessment has attracted increased attention from the international mathematics education community including this Korean community also. There could be numerous reasons for this phenomena. During the last couple of decades the field of mathematics education has developed considerably in the area of goals, theories, and practices. Whereas these developments have not been matched by parallel development in assessment. Now the functions, roles, and effects of assessment in mathematics education should no longer be neglected, rather they should become objects of investigation and examination in the study of mathematics education. The purpose of this study is to explore selected international cases of assessment in mathematics education mainly depended on two studies resulting from ICMI Study Conference on Assessment in Mathematics Education and Its Effects; and then to draw out their suggestions needed for our study of assessments in mathematics education.

We have compared Korean and American mathematics curriculums in 5 areas: whole number(concepts and its operations); geometry; pattern and relations; measurements; statistics and probability. We have found significant differences in geometry area. Korean curriculums contain simple planar figures (circles, triangles, rectangles, and squres) and some of the spatial figures until 3rd grades. But in America they learn various planar and spatial fugures(cone, pyramid, triangular prism, etc) since the 1st grade starts. They also start the 1st grade by dealing with topological concepts like open/closed, inside/outside, order, etc. As the grade goes on, students learn other geometrical concepts like congruence, symmetry, 3-dimensional views. We also found that American curriculum focuses on students' activities and courages communication through projects, groupwork, journal writing, etc. It's also superior in respects of motivation, and connections with real life and other subjects. Korean curriculum needs more improvements in these aspects. Furthermore for lower graders reviewing sections need to be enhanced for feedback.

The primary purpose of this study is to investigate problems with the current mathematics textbook. According to a survey, the following were the findings: Textbook is only a tool-book for introducing mathematical facts. It is a unique book for all students possessing different level of mathematical ability. There is difficulty in teaming math using technological devices and in activating(mental and concrete) manipulative activities. There is difficulty in communicating while doing mathematics. There is lack of defined and developed layout of textbook, et. al. It can be however found that these problems can be solved to some degrees, when mathematics textbook is developed based on constructivism. Recently, in mathematics education, it has been gradually emphasized that constructivism can be powerful in teaching and learning mathematics. There are however some difficulties in developing mathematics textbooks to reflect constructivism, such as to fill the gap between the contents written in the national curriculum determined in advance and the contents which students construct psychologically or socially in mathematics class.

This paper discusses jLogic, a mathematical logic education software developed by the author. jLogic is basically a MS-Windows based software that can construct first-order models, formulas and thet their satisfiablity. Logical formulas are easily input by a "keyboard" maintained by jLogic. A special finite model, called the "Toy World" can be visually cinstructed and modified. The user is supposed to answer the following 3 questions about the selected logical expression: 1. Is it a grammatically correct logical formula? 2. Is it a sentence that has a definite truth value? 3. Is th sentence true or false? When the user inputs his answer in the "Inspector window" and then presses the OK button, jLogic instantly tests the validity of the answer and tells the user the result. jLogic is freely downloaded from http://gauss.kyungpook.ac.kr/~jlogic/

This research investigates the development trend of the elementary school facilities in Japan. To achieve this purpose, it is investigated that policies and the necessary area and the plans of 14 priorities at the elementary schools which have been built since mid 1970's in Japan. And plan compositions are analyzed focused on the classroom & multipurpose space and the concept of the plan. In this study, the elementary schools are analyzed as the following three specific features: 1. the countermeasure for the variety of the teaching methods, 2. the concept of dwelling space, 3. the concept of community center. The result of this study can be the fundamental data for a plan of the elementary schools in Korea in the future.

The purpose of this study is to suggest how to use the piloti space at a primary school planning which is the critical element of an exterior space. On the process, we define the Piloti function as the connection of exterior spaces and the community and the parking lot. These research data give us helpful ideas to plan a positive exterior space at an elementary school by use of piloti space, in terms of its suitable location and size.

In the rapidly changing field of Management Information Systems, the definition and educational programs must be continually reevaluated and revised. A study was conducted to find a way to which the modeling principle is applied for redefining the identity of Management Information Systems as an independent academic field and to develop a plausible MIS curriculum based on the modeling principle. Previous researches on the MIS frameworks, knowledge and technology requirements for IS professionals, and standard MIS curriculums were reviewed thoroughly. For this study, the Kantian cognitive model was adopted as a basis of modeling principle. The result shows that modeling ability has been the core competence of IS people in the field of MIS. The applicability of a modeling principle is also verified in establishing the identity of MIS and developing a normative MIS curriculum. For the MIS field to thrive as an independent academic field and research discipline, it is believed to be imperative for the discipline to have a unique educational goals distinguished from both other management areas, and sub-fields of computer science.
