In this article, I identified many points of commonness and differences at)feared in the fraction units of three conspicuous textbooks -McLellan, MiC and Korea. After that, 1 evaluated these results with reference to more general didactics on which each text-book is based. A background theory of Mc-Lellan's textbook was Dewey's experientialism, and that of MiC was Freudenthal's realistic mathematics education. Through this study, I have reached the fact that these three textbooks could not exhibit the phenomenological wholeness of fraction. Driven by measuring number model which is very abstractive, McLellan's text-book is disregarding the lower level context. MiC textbook, driven by real context, is ignoring higher level model which is close to rational number concept. From an excess of formulation and practice of algorithm, Korea's textbook is overlooking the real context. It is necessary that a textbook which would display the phenomenological wholeness of fraction is developed.

한국정보올림피아드 경시대회 초등부 전국대회를 준비하는 학생들을 위해 본 교재를 개발하고자 한다. 본 교재는 J.S.Bruner의 표상이론에 맞게 알고리즘의 진행 절차를 시각화하여 이해가 쉽고 빠르게 되도록 구성하였으며 이를 실제 코드로 작성하여 자신의 논리를 프로그래밍 언어로 표현할 수 있게 하였다. 또한 기출문제, 확인문제 등을 통하여 배운 알고리즘을 확실하게 익혔는지 확인한다. 이러한 교재 개발이 경시대회를 준비하는 초등학생들에게 관련 도서가 전무하여 기회를 놓치버리는 일 등이나 사교육비를 들여 학원에만 의존해야 하는 최근의 경향에 대한 대안으로 사용되기 바란다.

'증거기반 교육'은 개인적 경험이나 성공 사례, 그리고 전통적인 속설보다는 과학적 연구결과와 근거가 중심이 되는 교육이다. 증거기반 창업 교육은 기존 속설과 믿음, 단편적 성공 사례로 인해 고착된 인지 편향을 완화시켜 중립적인 시각을 견지할 수 있으며, 직관과 경험을 넘어 데이터와 연구 결과에 의해 의사결정을 하는 분석적 자질을 연마하는데 기여한다. 본 논문은 현재 국내의 증기기반 창업교육의 현주소를 명확히 파악하기 위하여 1999년부터 2021년 출판된 49권의 창업교육 대학 교재를 분석하였다. 구체적으로 모든 도서의 내용을 1)창업기초, 2)비즈니스모델, 3)마케팅계획, 4)재무계획, 5)운영계획, 6)창업유형, 7)절차 및 제도의 각 7가지 기준으로 구분하고, 각각 사례, 단순통계, 변인 통계, 선행 연구의 비중을 분석하였다. 분석결과 증거의 핵심인 선행연구의 비중은 전체 교재의 총 분량 중 11.25%를 차지하는 것으로 나타났다. 이는 Charlier(2011)의 MBA 교과목 대상으로 조사한 결과와 유사한 값이다.

Recently an extensive study of the mathematicians who have overcome the visually impaired and contribute to the academic in math was published. In the case of Korea, we can find there are mathematicians who have overcome physical disabilities such as cerebral palsy and polio. However there is no example of blind person who majored mathematics to become a mathematic's teacher or professor and have entered any mathematics related professions. This let us to study the reasons that caused difficulties to visually impaired students majoring in mathematics. We also suggest ways that may help blind students to have access to mathematics intuitively. In this study, we propose a tactile mathematics textbooks and teaching manuals utilizing 3D printing which the visually impaired students can touch and feel. We can supply such materials to visually impaired youth, special education teachers and parents in Korea. As a result, visually impaired students will be able to access mathematics easily and can build their confidence in mathematics. We hope that some blind students with mathematical talent do not hesitate to major mathematics and choose career in mathematical professions.

The purpose of this study is to provide a method to help elementary school students learn ratio-related concepts effectively through visual representations. This study was conducted to identify the differences in the composition of ratio-related concepts between Korean and Singaporean textbooks, reconstruct a unit of proportional expressions and distributions by using visual representations and confirm the differences in performance between an experimental and a comparison group of 6th grade students. While the experimental group mathematics lessons is from the reconstructed textbook, the comparison group lessons is from an existing textbook that does not include any reconstructive representations. A t-test of mean was applied to determine the differences between the experimental and comparison group. Analysis revealed significant differences in the mean between the experimental group and the comparison group, and the intermediate level group showed more improvement compared to the higher and lower level groups. An implication of this study is that the application of visual representations can assist students' understanding of ratio-related concepts.

In this study, we conducted a textbook analysis and a conceptual test in order to investigate misconceptions of preservice chemistry teachers in understanding motions of molecular gases. As a result, we found out that many of the general chemistry textbooks not only introduce motions of molecular gases by explaining basic conceptions and using simple models, but also omit the explanation on center of mass when dealing with rotational motion. The physical chemistry textbooks, however, mainly approach motions of molecular gases in terms of spectroscopy and use various models to explain more intensified concepts, referring the center of mass in rotational motions. Meanwhile, pre-service chemistry teachers' confidence and understanding in the motions of molecular gases were very low and pre-service teachers also had many misconceptions about them. We believe this is because they had a tendency to depend largely on their intuition based on the pre-conceptions and the visual materials in the textbooks.

The purpose of this study is to examine visual elements in Korean high school English textbooks and compare the results with Hill's (2003) which attempted to analyze visuals in British EFL coursebooks. In this study, all 15 English textbooks of high school year 1 in Korea were selected and analyzed. On the basis of the analysis and comparison, the following results have been obtained. First, there were some similarities and differences between the two kinds of texts-Korean high school textbooks and British EFL coursebooks. One similarity was found in regard to the average of pictures and drawings. Second, it was found that in both cases, more pictures were used than the drawings. Third, with regard to the identity of the pictures and drawings used in both texts, there was a higher degree of the use of people than that of objects. Finally, it was found that the pictures and drawings were used more for decorative purpose rather than for the purpose of actual use in teaching and learning. The findings of the current study will shed light on visual impact in EFL coursebooks and explore ways to provide learners and teachers with meaningful learning and teaching experiences.

The purpose of the study wast to determine the effect of slides exposure of different cultural architecture and interiors on students discriminating abilities of cultural differences among China, Japan, and Korea. Pre-test post-test experimental design was used. To measure students cultural discriminating abilities, a scale of 48 graphic items representing latticeworks of 3 countries was designed. For the treatment, 20 pictures showing representative architecture and interior spaces of each country thereby a total of 60 slides was selected. Subjects were 118 undergraduate students majoring in interior design. After measuring students' critical ability, the slide images were shown in country's order without explanation. After the exposure, post measures with the same instruments were done. To find the statistically significant difference, paired t-test was used. result indicated that the slide exposure have direct and positive influence on students cultural discriminating abilities. Therefore the model can be efficiently used in the educational setting to give student experience of cultural diversity.

The interaction effects of the cognitive style and the presentation order of learning material was explored in the study. Visualizers performed better when the graphic information was presented prior to the verbal information, whereas verbalizers did better when the verbal information was presented prior to the graphic information. The results of the present research have practical implication of personalized multimedia design based on the learner's cognitive style. The results also have suggested that the cognitive load of a multimedia material can be varied depending on the compatibility of the cognitive style and the material.
