This study investigated the connections of mathematical thinking of students at the second, fourth, and sixth grades with regard to multiplication, fraction, and proportion, all of which have multiplicative structures. A paper-and-pencil test and subsequent interviews were conducted. The results showed that mathematical thinking including vertical thinking and relational thinking was commonly involved in multiplication, fraction, and proportion. On one hand, the insufficient understanding of preceding concepts had negative impact on learning subsequent concepts. On the other hand, learning the succeeding concepts helped students solve the problems related to the preceding concepts. By analyzing the connections between the preceding concepts and the succeeding concepts, this study provides instructional implications of teaching multiplication, fraction, and proportion.

This study was designed to determine (1) the effects of the following stop consonant on the vowel length in isolated bi-syllabic words, (2) the mechanism which renders vowels longer in duration before lax stops than tense stops, (3) where the aspiratory interval is included, in the vowel portion or the preceding consonantal portion and (4) the influence of the preceding consonants upon the duration of the following vowel. Measurements were made of five timing variables on acoustic signals as three native Korean speakers uttered isolated bi-syllabic /VCV/ words in which the vowel was identical, /$\alpha$/, and the C slot was filled with bilabial stops. Findings: (1) the vowel length before the lax stops was significantly longer than before the tense stops, while the difference in the vowel duration between the tense stops was insignificant or negligible, (2) the vowel length varied as a function of the articulatory force of the following consonants, regardless of the phonological unit of syllable, (3) The aspiratory interval is interpreted as a portion of the preceding consonant and (4) The effects of the preceding consonants on the final vowel length were not rule-governed.

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.

According to the modernization of mathematics education, new abstract concepts such as the concept of sets are introduced in many fields of it. The purpose of this thesis is to adopt the concept of sets to 'probability' which is included in the curriculum of high school matematics education. The considerations of the preceding chapter III, and their obvious generalizations to more complicated experiments, justify the conclusion that probability theory consists of the study of sets. An event is a set, its opposite event is the complementary set; mutually exclusive events are disjoint sets, and an event consisting of the simultaneous occurrence of two other events is a sets obtained by intersecting two other sets it is clear how this glossary, translating physical terminology into set theoretic terminology, may be continued. Furthermore, the important theorems of probability; Additional theorem, multiplication theorem, their applications and so on, are proved by the technical operations of sets. Thinking of the mathematics education introduced by the concept of sets is very important in future.

It is necessary for humans who have been facing environmental problems to build a sustainable society in which economic activities coexist with nature. To realize such goals, it is essential to promote and enhance environmental education, and to raise global awareness of environmental issues. As a preceding study, a board game "Ecopoly" based on the Kyoto protocol and the estate dealings game, was developed and the validity of environmental education was verified. This study further aims to develop a computer game "Ecopoly", based on the board game which enables us to learn the relationship between environmental problems and economic activities, and to learn more about environmental problems. This computer game enables to concentrate on it by automatic complicated calculations, and to get a higher visual effect compared with the board game. Experimental testing of the game was conducted with 13 college student subjects, and the validity of the game was verified.
