The objective of this study is to find an educational method that is able to increase creativity using both left and right directed thinking with complementary cooperation. The premise of experimental study is that analogical inference is a great help to produce a creative design, and the design tasks of residential space are given to 20 students, voluntary participants in four experimental tests. The first test is conducted with fundamental conditions such as site or location, users and their design requirements. Other three tests make a clear distinction with three cases using verbal analogy from many keywords, using visual analogy from many images and using verbal visual analogy from keywords and visual images. Consequently, when students use both verbal and visual analogy in solving design tasks their creative ability qualitatively as well as quantitatively is higher than in using only verbal analogy or visual analogy. Further study will be progressed with the design tasks of residential space in order to have an effective verification by comparing students' design results classified into two groups. One is a control group that consists of sophomore students in a college and another is a comparison group that consists of sophomore students in an university.

The objective of this study is to find a educational method that is able to increase creativity using both left and right directed thinking with complementary cooperation. The premise of experimental study is that analogical inference is a great help to make a creative design, and design tasks of commercial space, fashion shop and herb cafe are given to 25 students, voluntary participants in experimental tests. Tests make a clear distinction between a case using verbal analogy from many keywords and another case using verbal visual analogy from keywords and visual images. Consequently, when students use both verbal and visual analogy in solving design tasks their creative ability qualitatively as well as quantitatively is higher than in using verbal analogy. However, when students are classified with high and low sketching group verbal visual analogy is effective for students with high sketching ability to enhance both practicality and originality. Even students with low sketching ability can improve originality remarkably by using verbal visual analogy. In experiment there is time limit, a hour, but in actual studio class it is desirable that an educator guides the latter to make up for the weak points in practicality of their design taking time. Further study will be progressed with the design tasks of residential space to compare with the findings of this study.

This paper reports on an experimental study of the absorption of COS in a secondary amine diethanolamine. The primary objectives were to investigate an analogy between $N_2$O and COS, thereby allowing an estimation of the physical solubility and diffusivity of the sulfur gases in the reacting amine solutions. The solubilities and diffusivities of $N_2$O and COS in 5~25% aqueous polyethylene glycol at $25^{\circ}C$ were measured. The results appeared to verify the use of an $N_2$O-COS analogy for estimating the solubility and diffusivity of COS in aqueous solutions of alkanolamines up to an approximate 25 weight % concentration. The mean deviation of the $N_2$O analogy relative to the measured solubilities was 3.7%, and the mean deviation between the analogy and the measured diffusion coefficients using the experimental values for Hcos/PEG was 14.6%.

Analogical reasoning is a central component of human cognition and contributes to scientific discovery and to develop science education. In this study, we investigated the process features of lower elementary school students' analogical reasoning to explain mixture concept. The subjects are 24 lower elementary students. And the research design includes three phases instruction to investigate the features of students' self generated analogy. Phase 1 is the introduction of analogy in which student learn to use analogy. Phase 2 is a POE class about mixture conception. Piaget and Inhelder studied the conception of mixing among children in relation to cognitive development. In phase 2, we taught the student with Piaget and Inhelder's the experiment and observed the features of learning process about mixture conception. Phase 3 is students' generation of analogy (self generated analogy) for the experienced phenomena in phase 2. We analyzed the students' responses through the three phases in the view of Gentner's Structure Mapping Theory. The results showed that many lower elementary school students even before formal operation stage understood the mixture conception and made well their self generated analogy to explain the mixture conception in spite of the difficulty of making self generated analogy.

This study presents an idea of using analogy concept to the heat transfer studies regarding the HTGR development. Theoretical backgrounds regarding the idea were reviewed. In order to investigate the predictability of a mass transfer system for heat transfer system phenomenology, an electroplating system coupled with a limiting current technique was adopted. Test facilities for laminar forced convection and natural convections under laminar and turbulent conditions were constructed, for which heat transfer correlations are known. The test results showed a close agreement between mass transfer and heat transfer systems, which is an encouraging indication of the validity of the analogy theory and the experimental methodology adopted. This paper shows the potential of the experimental method that validates the little-understood heat transfer phenomena, even in complex geometries such as HTGR.

The purpose of this study was to develop an instrument for assessing teachers' awareness of science teaching through analogy (ASTA) and to establish its validity and reliability. Based on the literatures on science teaching with analogies, we constructed 23 survey items. Face validity of the items was established using three science education experts. Through exploratory factor analysis with responses of 35 pre- and 26 inservice elementary school teachers, the instruments were constructed on four subcategories: awareness of analogies in science, use of analogy in teaching and learning, self-efficacy in science knowledge, and knowledge of analogy. The data collected from pre- and in-service elementary teachers demonstrated that overall the teachers' awareness of analogy in science was neutral, which indicated they did not have clear standpoints of science teaching through analogy. Further examination demonstrated that there was no significant difference between pre- and in-service teachers and between two genders. Moreover, there was no significant difference among teachers who preferred either didactic or discovery teaching approaches. We conclude that ASTA test would contribute assessment of teachers' awareness of analogy in science teaching while further examination of the instrument will warrant for its broader use.

Personal creativity could be promoted and improved through many experience, training and various prior knowledge. This researcher had proceeded several preceding studies to find effective using methods of analogy for creativity enhancement. This study, following work of preceding studies aims to verify the effects of verbal and visual analogy for creativity improvement. Effect verification had been progressed by comparing the residential design results of two groups which are classified an experimental group consisted of sophomore college students with a comparative group consisted of sophomore university students. Consequently, the experimental group that had undergone many training on verbal and visual analogy in several preceding studies is superior to the comparative group in terms of creative design rate, sketch rate with high quality. Through this result it is verified that the using methods of verbal and visual analogy is very effective on creativity enhancement in interior design process. But the limitation of this study is that there were a few populations. Nevertheless, interdisciplinary this study will be used as a practical one to suggest a model on a teaching method and a theory for creativity improvement in interior design education.

In this paper we consider some properties of. bisector of interior angle(theorem 1) and exterior angle(theorem 2) in triangle by using analogy. As a result of analyzing various mathematics textbooks we have known that they focused not on relation between two theorems, but on describing two theorems. We have seen that theorem 2 is able to be inferred from theorem 1 by using analogy. After proving theorem 1 by some methods we analyze proof process, extract proof ideas, and analogize some ideas for proving theorem 2. From this we are able to find relationships between theorem 1 and 2.

이 연구에서는 비유 생성 전략을 개발하여 이를 중학교 1학년 과학영재 수업에 적용하였다. 그리고 이 수업에서 5개 소집단의 과학영재들이 생성한 비유의 유형 및 과학영재들의 언어적 상호작용 양상과 비유 생성 패턴 및 비유 생성 전략에 대한 과학영재들의 인식을 조사하였다. 분석 결과, 비유 생성 전략을 활용한 수업에서 과학영재들이 개별적으로 생성한 비유는 일반적인 비유 생성 활동에서 보다 질이 좋은 유형의 비율이 높았으며, 소집단 활동을 거친 후에는 대부분 가장 좋은 유형의 비유를 생성하였다. 과학영재들의 언어적 상호작용은 각 단계의 영역별 하위 범주의 상호작용의 빈도 및 비율에서 약간 다른 경향이 나타났다. 그리고 소집단별 비유 생성 패턴은 심층적 소재 선택형, 포괄적 소재 선택형, 표면적 소재 선택형의 세 가지 유형이 나타났으며, 각 유형별로 대응 정교화 패턴이 다르게 나타났다. 과학영재들은 비유 생성 전략의 가치 및 태도 측면에서 긍정적으로 인식하고 있었으며, 비유 생성 전략이 더 정교한 비유를 생성하고, 창의적 사고를 하는데 도움이 되었다고 응답하였다. 따라서 비유 생성 전략은 과학영재들의 창의성 신장에 긍정적인 영향을 줄 것으로 기대된다.
