Learning computational thinking is very important in programming education. Computational thinking refers to the problem solving ability based on the theories of computer science, indicating the importance of algorithm thinking. That is the reason for focusing on promoting creativity and improving the problem solving ability of the students in programming education. This paper commented the elements to consider for teachers when teaching computational thinking to elementary school students with online coding education website 'code.org' that helps beginners have easy programming experiences based on the characteristics of the website, and proposed the appropriate teaching methods.

학습에 동기부여를 위한 도전들이 있는 상황을 증진시키는데 효과적이고 도움이 되는 정보에는 어떠한 종류들이 있는지 조사되고 있다. 특히 Keller(1998)의 동기유발 요소 중에서도 학습자들의 요구나 흥미, 학습할 내용과의 관련성을 제시하는 것이 학습 동기와 학업성취를 높인다고 밝히고 있다. 그러나 이런 동기유발 요소만으로 학업성취가 높아지는 과정을 모두 설명하기는 부족하다. 웹기반 학습에서는 학습에 대한 의지를 지속시키지 않으면 학습자들이 학습에 대한 인지적 과부하와 방향상실을 경험하게 되어 오히려 학습의 효과가 떨어지게 된다. 이러한 관련성과 학습 의지적 요소에 관한 선행연구들을 바탕으로 웹 기반 학습에서 관련성과 학습 의지 요소 전략의 사용이 학습 동기 및 학업성취에 미치는 영향을 밝히고자 한다.

The circumcenter of a triangle is introduced in logic geometry part of 8th grade mathematics. To handle certain characteristics of a figure through mathematical proof may involve considerable difficulty, and many students have greater difficulties especially in learning textbook's methods of proving propositions about circumcenter of a triangle. This study compares the methods how the circumcenter of a triangle is explored among the Elements of Euclid, a classic of logic geometry, current textbooks of USA and those of Korea. As a result of it, this study tries to abstract some significant implications on teaching the circumcenter of a triangle.

This paper illustrates a prototyping framework of the documentation-standards retrieval system via the data mining approach for enhancing software development quality. We first present an approach for designing a retrieval algorithm based on data mining, with the three basic technologies of machine learning, statistics and database management, applied to this system to speed up the searching time and increase the fitness. This approach derives from the observation that data mining can discover unsuspected relationships among elements in large databases. This observation suggests that data mining can be used to elicit new knowledge about the design of a subject system and that it can be applied to large legacy systems for efficiency. Finally, software development quality will be improved at the same time when the project managers retrieving for the documentation standards.

This study examines the changing process of standard and development of school library in advanced countries including Britain, United States, Japan and Korea. Also, this study compares and analyzes recent school library standards in the each countries. The examination is based on the common elements including staff, material, environments, management, cooperation system, and learning skill showed in the each of advanced countries. Finally, the study suggests the model of reasonable standard for the activation of school library in Korea.

The new movement in science education in America and Europe has been heavilly oriented into technological and soceital aspect of science since 1970. However, this spirit has not been well informed in Korea and not adapted in science education. This paper aimed to arouse Korean science educators attention to everyday situation as a science education context. In this paper, the discipline centered science education was briefly reviewed and problems related to the philosophy was pointed out. At the same time the researcher introduced STS context as a science education objective, and elaborated the three elements(physical situation, technological situation. and societal situation) of the context. In the paper, the advantages of the use of everyday context in science education were examined. THe advantages were analysed in terms of the nature of science, learning psychology, integrated science, and societal aspect of science education. The paper also suggested the criteria to select teaching materials from STS context. The suggested criteria were the degree of science concepts involvement, frequency of experience, strength of experience, and possibility of direct experience.

In this paper, we propose to investigate the existing EPL education related studies and to collect the total effect size for the improvement of high-level thinking through meta-analysis and to confirm the effect size according to various variables. So, we have objectively identified and generalized the practical effects of EPL education on the various elements of high-level thinking and high-level thinking. The results of the meta-analysis showed that 1) EPL is a teaching-learning tool that greatly improves students' high-level thinking. 2) Education based EPL has greatly contributed to the enhancement of creative thinking and logical thinking among high-level thinking. 3) Kodu, App Inventor, Scratch, and Dolittle was confirmed that the effect on the improvement of high-level thinking was great.

Visual images are important elements of the communication of environment in secondary school environment textbooks, which dominate classroom approaches to teaching and learning. This study was to analysed the perspectives of pedagogical and social-pedagogic of visual images in 'global warming' unit of six different Korean environment textbooks. Analysis makes use of the dimensions pedagogical functions, content specialization, social-pedagogic relationships, and abstraction of the visual codes. The results showed that most of the visual images in school environment textbooks tend to establish social-pedagogic relationships with students. The results of our study have implications for textbook authors and secondary environment teachers. We suggest that future studies may focus on students' and teacher's interpretation of visual images new secondary environment textbooks.

Korea has relied on top down development method, in which companies, research and education institutions move into the industrial complexes established by the government. However, to improve local competitiveness, the paradigm is shifting from the government initiated industrial complex to the clusters based on the cooperative network of the region. Representative case is 'Samcheok-si Fire & Emergency industry cluster construction project' that begun in 2007. AHP technique analysis results on first-stage showed that priority was on policy and network elements, and the results of second-stage analysis show that priority was on Policy incentives to internationalize the cluster and strengthen link,. Cluster branding, Sharing of organizational culture to cope with changes in environment, Creation of group learning culture. The subject of this research is limited to Samcheok-si's the Fire and Emergency Industry cluster formation project. Therefore, the research area and standard should be expanded to increase generality in further researches.

This paper proposes a method which analyzes facial shape and extracts positions of eyes regardless of the tilt and the size of input iamge. With the extracted feature parameters of facial element by the method, full human faces are recognized by a neural network which BP algorithm is applied on. Input image is changed into binary codes, and then labelled. Area, circumference, and circular degree of the labelled binary image are obtained by using chain code and defined as feature parameters of face image. We first extract two eyes from the similarity and distance of feature parameter of each facial element, and then input face image is corrected by standardizing on two extracted eyes. After a mask is genrated line historgram is applied to finding the feature points of facial elements. Distances and angles between the feature points are used as parameters to recognize full face. To show the validity learning algorithm. We confirmed that the proposed algorithm shows 100% recognition rate on both learned and non-learned data for 20 persons.
