This study analyzed high school informatics textbooks that were developed based on the 2015 Revised National Curriculum. Content analysis was adopted to analyze the organization system of the textbooks. Learning objectives were also analyzed according to Anderson's taxonomy of educational objectives. Through content analysis, it was revealed that the textbooks were composed of activities, differentiated learning, and small group learning to promote core competencies. The analysis of learning objectives of the textbooks showed that 'understanding' (41%), 'developing' (20%), and 'applying' (18%) were the three highest criteria in terms of cognitive processes; in terms of type of knowledge, conceptual knowledge accounts for the highest(45%), followed by procedural (32%), and factual (12%). Further methods to improve the textbook quality is proposed based on the results from this analysis.

Theories and concepts emerging in new media environment are influencing the field of current spatial design. Art and technology have always coexisted, not but they are differentiated in two parts. They show new communicational paradigm in terms of supplementary position each other. The fact that examining the expression method and the communicational structure of today's new media art will be an analytical tool which analyzes the concepts of contemporary spatial design. For this, we attempt to use the Bolter and Gusin's remediation theory as analytical tool. First of all, we consider its theoretical aspects, and then, classify them according to the creation method, and investigate the characteristics of expression according to their types. We prepared an framework of analysis using the Remediation theory and its traits. We reviewed the relations between new media and spaces concerning remediation. After researching, we could analyze the cognitive aspects between new media and spaces as immediacy, and recognize the operational aspects of visual image as hypermediacy. Through the analysis, we could recognize the traits that digital environmental simulacres, sense of telepresence, and non-linear hypermediacy etc. remediate with repeating of mediation of mediation.

Creative thinking in education is a common assumption to be accomplish in this information age. Information education can contribute to build the ability to think creatively. The Author explored how information education conduces the creative thinking ability that is necessary to the development of independent and competent study for students themselves. The writer also expressed the integrated education makes students think synthetically and synthetic educational experience derives creative thinking. She based her arguments upon the theory of the psychology of memory and the Piaget's cognitive structure. To increase the effects of information education, it is necessary to integrate the curriculums and learning method of the information education and those of other areas of learning, i,e., languages, literatures, social sciences, sciences, mathematics, etc. Here, author asserted that the teaching of information skill within classroom curriculums for all subject areas can make the integrated effects on various classroom curriculums. On the basis of the findings of this study, the author recommended that every school needs to prepare enough books and other media for the students to drill information skill. Consequently, to build creative thinking ability for He students, librarians, classroom teachers and school principals who have influence on the information education, have to cooperate to initiate integrated information education for the student.

This paper has been studied about algorithm teaching methods for improving the problem-solving skills and creativity in rapidly changing information society. Especially the algorithms for teaching about computer is very important. Because it is effective learning content for finding the best solution to solve a problem and improve the students' logical thinking. However, teaching algorithms can be monotonous to children on account of using only computer and languages. So It needs to consider about the cognitive structure and level of elementary school students. Therefore, this study has the purpose to acquaint students with the principle of algorithm and improve problem-solving and creativity using games, not computer.

This study proposes a new instructional strategy and corresponding materials designed from various alternative frameworks to help students understand evolution as a biologically acceptable theory. Biology teachers have normally taught the evolutionary mechanism by means of comparing Lamarckism with natural selection. In this study, a new instructional strategy in which the Lamarckian explanation is first excluded because Lamarckism is known to be subsumed in a learner's cognitive structure as a strong preconception of evolution is suggested for teaching evolution. After mutation theory is introduced, Darwinism including natural selection is explained separately during the next class hour. Corresponding instructional materials that aid student understanding of the evolutionary mechanism were developed using recently published articles on human genetic traits as scientific evolutionary evidence instead of the traditional evolutionary subject matter, giraffe neck. Evolutionary evidence from human genetic traits allows students to exclude anthropocentric thoughts effectively and raise concern for the phenomenon of evolution positively. The administered instructional strategy and materials in this research improved student conception, concern, and belief of evolution and it is believed that they helped students understand the evolutionary mechanism effectively.

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.

The aims of this study are to develop the STEAM program focused '3D printing for respiratory system' and to ascertain its influence on elementary student's science process skills, creative problem solving abilities and scientific interest. The developed STEAM program was applied to 5th grade students of O elementary school located in J city. As a result of applying the STEAM program, the experimental group of the STEAM program class improved significantly in creative problem solving abilities and scientific interest than the control group of the theoretical class. The result of learner satisfaction survey of the STEAM program was high. Meanwhile, there was no significant difference in science process skills between the two groups. Therefore, the STEAM program class with the theme of '3D printing for respiratory system' could be meaningful works to encourage students' interest as well as their creative problem solving ability and scientific interest. In future, continuous and systematic studies on STEAM programs focused on 'structure and function of our body' are needed for elementary students' cognitive and affective developments.

Current web accessibility checks and automatic assessments have been pointed out that the assessment items and scores are evaluated from the developer's point of view rather than from the user's one. In addition, although most of the grades of an automatic assessment on the public web sites are excellent because they are built in accordance with the web accessibility development guidelines, not a few web sites shows relatively low grades in evaluating their usability test made by those users. Taking into account the inadequacy of these web accessibility assessments, this study has identified the differences between the grades of usability evaluations and automatic evaluations for people with low vision and analyzed the major factors affecting web accessibility usability evaluations using Repertory Grid Techniques. Also, the Hard Laddering method of the Means-End Chain theory was adopted to visualize the relationship between Attributes-Conferences-Value and a hierarchical value system analysis based on FGI(Focused Group Interview) to people with the low vision. This study proposed the measures to improve the current web accessibility automatic assessment allocation, expert evaluation criteria, and user task assessment. In particular, it is a web accessibility user evaluation model that can consider the web accessibility quality certification criteria and user review assessment by directly analyzing the user cognitive structure and value system. This study is expected to be useful as a research to enhance the quality of web accessibility assessment.

As an exploratory attempt, this study examined the correlates of different strategic groups in the Korean health food industry. Many prior studies believe that different entry mode such as entry timing and patterns, and different cognitive structure of top managers lead to the formation of different strategic groups in the same industry. Different strategic groups with different sources or mobility barriers are also expected to produce different level of economic performance. Multivariate statistical analyses of data from 32 firms in the Korean health food industry revealed the following results. i) There are four different strategic groups with different levels of mobility barriers in terms of firm size, scope of product/market domain, degree of forward and backward integration. ii) Differences in both entry timing and environmental perception of top managers are associated with different stratetic groups. However, the patterns of entry are not significantly different among four strategic groups. iii) Four strategic groups exhibit different level of economic performance in terms of sales growth rate and return on investment. Finally, this study tried to identify commonalities and differences among various strategic groups found in several industries in Korea. The results offered some implications to search for developing a useful theory of strategic groups in Korea.

In estimating designed architectural buildings, many factors in various design domains such as function, structure, form, environment may be considered and then a building design might be selected or modified as final design. This paper proposed a method to obtain complexity values from two dimensional drawings which are floor plans or elevations. The method has been developed based on information theory, shape pattern representation and cognitive theory. Results of measuring complexity value can make the computer evaluate and select final results produced from automatic design processes by the computer That is to say, aesthetic values based on order and chaos can be measured using complexity values and then some results having superior values can be selected as final result.
