One of the most important aims in mathematics education is to enhance students' problem-solving abilities. To achieve this aim, in real school classrooms, many educators have examined and developed effective teaching methods, learning strategies, and practical problem-solving techniques. Among those trials, it is noticeable that Engel, Zeits, Shapiro and other not a few mathematicians emphasized 'Invariance Principle' as a mean of solving problems. This study is to consider the basic concept of 'Invariance Principle', analyze 'Invariance' concept in secondary Mathematics contents on the basis of framework of 'Invariance Principle' shown by Shapiro and discuss some instructional issues to occur in the process of it.

This paper presents the Global van Hiele (GVH) questionnaire as a tool for mapping knowledge and understanding of plane and solid geometry. The questionnaire facilitates identification of the respondents' mastery of the first three levels of thinking according to van Hiele theory with regard to key geometrical topics. Teacher-educators can apply this questionnaire for checking preliminary knowledge of mathematics teaching candidates or pre-service teachers. Moreover, it can be used when planning a course or granting exemption from studying in basic geometry courses. The questionnaire can also serve high school mathematics teachers who are interested in exposing their students to multiple-choice questions in geometry.

The purpose of this paper was to suggest new strategies available for the housing education considering the enhancement of professional practices in the housing industry. The purpose was accomplished examining the businesses of housing industries and the undergraduate programs in housing. The housing industry was considered in following areas: housing department of construction company. comprehensive marketing. management/lease and building/environment examination. And the undergraduate programs of nine universities offering housing as a whole or a half portion of the department were analyzed. Both the examination results and the suggestions including course recommendations, the educational-industrial cooperation programs, and the accreditation housing education program could be valuable informations for the housing educators.

건축공학과를 졸업하고 구조설계 실무 분야로 진출하는 이의 비율이 3~5%라는 비공식 통계가 있다. 이 통계 숫자가 말하듯이 건축구조설계업은 건축공학과 졸업자가 택하는 소수의 직업군에 속한다. 재학시에는 콘크리트 구조, 강구조 및 여타 구조 과목을 해당 분야를 전공한 교수진으로부터 각각 배우지만 실무에서는 맡겨진 프로젝트에 의해 구조 형식이 결정되고 스스로의 노력과 회사 내 시스템을 통해 해결해야 하므로 구조 형식 전반에 걸친 프로패셔널(professional)이 되어야 한다. 콘크리트에 대한 전문지식도 학교에서는 콘크리트의 기본 사항, 수직 및 수평 부재의 단면 설계 연습 등을 통해 기본적인 단계의 지식을 습득한다. 그러나 실무에서는 구조 시스템, 콘크리트 프레임의 거동 및 수많은 부재의 단면 설계 등과 같이 포괄적인 지식이 주종을 이룬다.(중략)

Cognitively Guided Instruction (CGI) is one of the most successful professional development programs for elementary mathematics teachers in US. This article introduces its theoretical background, research-based framework of addition and subtraction work, and how the program has been disseminated. Carpenter and Fennema started CGI aiming to develop a professional development program that focused on research knowledge of children"s thinking. Their goal was. to bring a significant change in teaching by helping teachers understand how children think mathematically. This 3-year NSF funded project grew to be 11-year long, and a number of publications have reported consistent successful learning and teaching by CGI students and teachers compared to counterparts throughout US. CGI′s success by focusing on improving teachers′ knowledge of children′s thinking offers possible opportunities for teacher educators to re-conceptualize teacher education in Korea.

Hospice, a concept of care for dying patients, focuses on providing comfort measures rather than aggressively searching for a cure. Hospice addresses symptom control from a wholistic view under the direction of an interdisciplinary team. Physical therapy fits with many of the tenets of hospice, such as the interdisciplinary team, inclusion of the patient and family as the care unit, provision of treatment in various in and out patient settings, and attention to the comfort of the patient. Physical therapy educators must recognize the need for medical ethics, psychosocial and medicolegal issues to be incorporated throughout the curriculum.

The purpose of this paper is to address He possibility of the teaching of 'proof' in elementary mathematics, on the assumption that proof in school mathematics should be used in the broader, psychological sense of justification rather than in the narrow sense of deductive, formal proof. 'Proof' has not been taught in elementary mathematics, traditionally. Most students have had little exposure to the ideas of proof before the geometry. However, 'Proof' cannot simply be taught in a single unit. Rather, proof must be a consistent part of students' mathematical experience in all grades. Or educators and mathematicians need to rethink the nature of mathematical proof and give appropriate consideration to the different types of proof related to the cognitive development of a notion of proof.

Algebra is important part of mathematics education. Recent days, many mathematics educators emphasize on real world situation. Form real situation, pupils make sense of concepts, and mathematize it by reflective thinking. After that they formalize the concepts in abstract. For example, operation in numbers develops these course. Operation in natural number is an arithmetic, but operation on real number is algebra. Transition from arithmetic to algebra has the cutting point in representing the concepts to mathematics sign system. In this note, we see the cognitive tendency of 10th grade about operation of real number, their cutting point of transition from arithmetic to algebra, and show some methods of helping pupils.

Motivating students to study mathematics is a concern for many mathematics educators. In this paper, we present the outcome of a one semester experiment in which group-work and academic advising were used as teaching strategies in order to improve the motivational level of our students in learning mathematics. Although the students' performance did not show any statistically significant difference between the experimental and control groups, qualitative and other quantitative data collected indicate that the participants in the experiment, especially weak students, have in one way or the other benefited from the teaching approaches. Details of the experiment, the findings and their educational implications are presented.
