  • The purpose of this study is to find out whether pre-service biology teachers' biological meanings of competition and adaptation is the same as everyday meanings to understand natural selection and evolution. Fifty three pre-service biology teachers answered written tests and thirteen of them were interviewed. The tests on general meanings on competition and adaptation, tests on biological meanings on competition and adaptation and tests on natural selection were administered. Questions on semi-structured interviews were composed of only biological meanings about competition and adaptation. Analyzing data through four steps, pre-service biological teachers' general meanings on competition and adaptation were compared with the definitions of Korean dictionary and compared with biological definitions. Pre-service teachers' alternative conceptions about biological competition and adaptation were classified and the alternative conceptual types were checked when explaining natural selection and evolution. They realized competition is battle for intention or purpose like everyday meaning of competition. However, they didn't realize adaptation happen in the population level. They thought that adaptation, like in everyday life meaning, is getting suitable to environment for survival on an individual level. By relating adaptation to evolution, they thought that long-lasting adaptation become evolution. This study has significance with respect to suggesting the alternative concepts of competition and adaptation based on effective evolution teaching from constructivism viewpoint and highlighting the importance of the concepts of biological competition and adaptation, which have been concerned rarely for a long time.

  • One of the most important objectives in science education is to develop students' science literacy. The purpose of this study is to analyze the relevance between biology instructional objectives in the 7th curriculum taught in elementary and secondary schools. For this study, 7 major parts in each grade were analyzed including cell, the form and function of plants, the form and function of animals, genetics, diversity, evolution, ecology, and environment. The strand map of instructional objectives is completed that represents the relation between the objectives. The summary of the results from this study is as follows. First, the concept about cells is not fully covered in lower grades including elementary schools. While the concept of energy metabolism is repeatedly covered, there is no concept of energy covered in learning the concept of energy metabolism in elementary schools. Second, the textbooks in elementary and middle schools have main concepts about the form and function of plants while those in high schools don't. The concept related to the part of the form and function of animals is repeatedly involved in the curriculum throughout the elementary, middle, and high schools. Third, the concepts such as genetics and evolution are involved in higher grades since these concepts are abstract ones. The part of genetics and evolution as well as diversity has no connection between grades in schools, so the development of "notion between" is necessary to relate these concepts with each other. Fourth, the 4 parts of diversity, ecology and environment, evolution, and the form and function of plants are covered in limited grade levels. The results of the relevance of gene in lesson goals will play an important rein as the primary material in developing the connection between textbooks in which lesson goals are closely related to each other throughout all grade levels in elementary, middle and high schools.

  • The range of graphic design has expanded very widely as the digital era emerged, and many new areas of film design, including film, DVD, interactive TV, mobile and DMB, began to require the work of designers. This could be considered as an application as well as a case of digital film design as it has more developed new media environment as basis. The change in the expression techniques of film language is inevitable since major consumers of new media are the younger generation. The method of creating and distributing visual communication work is not standing still anymore. It has been diversified through dynamic movements and changes resulting from interaction. The major objective of this study is to find out and suggest the directions that film and digital media graduate school education of future by researching and analyzing how the nature of design, as an academic subject that keeps on changing and developing, is evolving in the new media environment. For this purpose, the methods of appropriate education system in higher design education, which are derived from case studies and previous studies on education system, are evaluated by examining the consumers. This study aims at finding the most effective training method in film and digital media design, and by integrating current design education with digital film design education establish a better fit education system that complies with the demands of today's society. It will suggest how an educational institute should see ahead of the time and provide what the society will demand in the future.

  • Previous studies have investigated the similarity between the development of evolutionary explanations and students' conceptual developments on evolution. However, the validity and reliability of the assessment method reflecting the similarity have not been quantitatively examined yet. In addition, no study has examined the conceptual progressions of evolution concept based on contexts although literature has addressed the contextual difference of evolutionary explanation in the history of science. This study examined the validity and reliability of history-of-science-based evolution concept assessment using ordered multiple choice (OMC) methods and Rasch analysis and explored conceptual progression by three contexts (e.g., human, animal, and plant). The evolution concept assessment developed by Ha (2007) was used to examine 1711 elementary, middle, and high school students, and pre- and in-service science teachers' (biology majors and non-majors) evolution concepts. Internal consistency reliability and item response fitness of the OMC method that provide 0- to 4-point scores to creationism, teleology, intentionality, use/disuse, and natural selection respectively met the benchmark based on the Cronbach alpha and MNSQ indices of Rasch analysis. The level of elementary and middle school students' evolution concepts were located between intentionality and use/disuse while the level of high school and non-biology science teachers' evolution concepts were located between use/disuse and natural selection. The conceptual progressions of evolution concepts were differentiated according to three contexts. This study provided the quantitative evidence for the similarity between the development of evolutionary explanations and students' conceptual developments on evolution and suggest new analysis methods (i.e., OMC) of evolution concept assessment.

  • To derive brain-based evolutionary educational principles, this study examined the studies on the structural and functional characteristics of human brain, the biological evolution occurring between- and within-organism, and the evolutionary attributes embedded in science itself and individual scientist's scientific activities. On the basis of the core characteristics of human brain and the framework of universal Darwinism or universal selectionism consisted of generation-test-retention (g-t-r) processes, a Model of Brain-based Evolutionary Scientific Teaching for Learning (BEST-L) was developed. The model consists of three components, three steps, and assessment part. The three components are the affective (A), behavioral (B), and cognitive (C) components. Each component consists of three steps of Diversifying $\rightarrow$ Emulating (Executing, Estimating, Evaluating) $\rightarrow$ Furthering (ABC-DEF). The model is 'brain-based' in the aspect of consecutive incorporation of the affective component which is based on limbic system of human brain associated with emotions, the behavioral component which is associated with the occipital lobes performing visual processing, temporal lobes performing functions of language generation and understanding, and parietal lobes, which receive and process sensory information and execute motor activities of the body, and the cognitive component which is based on the prefrontal lobes involved in thinking, planning, judging, and problem solving. On the other hand, the model is 'evolutionary' in the aspect of proceeding according to the processes of the diversifying step to generate variants in each component, the emulating step to test and select useful or valuable things among the variants, and the furthering step to extend or apply the selected things. For three components of ABC, to reflect the importance of emotional factors as a starting point in scientific activity as well as the dominant role of limbic system relative to cortex of brain, the model emphasizes the DARWIN (Driving Affective Realm for Whole Intellectual Network) approach.
