In this study, we examine whether the description of the elementary science curriculum guide, the concept of evolution, and the beliefs of teachers affect the teaching practice in classes related to adaptation of elementary school teachers. First, we examined the alternative concept among the sentences described in the bio-adaptation-related unit of the 2009 Elementary Science Curriculum Teacher's Guide and identified the effects of this description on the teaching practice of elementary school teachers. Next, six elementary school teachers were classified according to the results of the evolutionary concept test paper and the evolutionary belief test paper, and based on the class recording data and interview data, whether there is a difference in teaching execution. As a result, it was confirmed that there were a total of 18 descriptions corresponding to the concept of evolutionary alternatives in the analysis of instruction descriptions, and that these descriptions influenced elementary school teachers' adaptation concepts and teaching practice. Next, the group with high and low levels of evolution differ in the areas of "recognition of importance in the unit, distinction between adaptation concepts in the general sense and adaptation concepts in the biological sense, errors in the class," and "recognition of evolutionary education needs in the elementary curriculum." This study is meaningful in that it qualitatively confirms the research on the evolution concept of elementary school teachers, which has been approached quantitatively, and in-depth, confirms how the description, evolution concepts, and evolutionary beliefs affect elementary school teachers' biological adaptation concepts.

This study aims to explore the differences between Korean and United States college students regarding their degree of religiosity, interest in, understanding and acceptance of evolution, and the effects of their interaction on these variables. A total of one thousand and fifteen Korean and US biology majors and non-majors college students participated in this study and a sub sample of 516 students were randomly selected for statistical tests. The results illustrated that Korean college students harbored significantly lower degrees of religiosity and interest in evolution but significantly higher degrees of knowledge and acceptance of evolution than US college students. The path analysis uncovered that the knowledge of and interest in evolution played a mediating role between religiosity and acceptance of evolution. Korean college students' interest in evolution was less correlated to other variables than US college students' interest. The acceptance of evolution was less predicted by knowledge of evolution in the Korean biology major sample than in the US biology major sample. The acceptance of evolution was predicted more by religiosity in the Korean non-major sample than in US non-major sample. This study suggests that future Korean science curriculum for evolution needs to enhance the degree of students' interest in evolution. In addition, future Korean science curriculum needs an instructional strategy in developing students' ability to make scientific decisions, such as the acceptance of evolution, without interference from their personal religious belief.

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.

The purpose of this study was to investigate pre-service biology teachers' perception of the evolution. This study was to compare the views of pre-service biology teachers with no religion with those of christian preservice teachers. Subjects were 77 pre-service biology teachers who enrolled in an university and graduate school of education located in Seoul. The instrument of this study was a questionnaire which consisted of 14 items on 2 domains: the nature of science, the origins of human beings. The key results are as follows. Most pre-service teachers showed highly understanding of the characteristics of science. However pre-service biology teachers still possessed naive views on the distinction of law and theory. In terms of the methods of science, many of the pre-service biology teachers considered scientific theories to progress through the accumulation of observation and experiments or through changes and modifications in existing theories. Compared with the pre-service teachers with no religion, christian pre-service teachers had conflicting views and misconceptions about the origins of human beings. The factors of religion were found to be one of the important barriers which prevent them from understanding the origins of human beings. The results suggested that the education program for pre-service biology teachers integrating the concepts and development process of the scientific knowledges should be effective for understanding the nature of science. For pre-service biology teachers, It is important to understand conflicting views of the christian pre-service teachers who understand creationism as a science.

This paper is the result of constructing information processing system such as living creatures' brain based on artificial life techniques. The living things are best information processing system in themselves. One individual is developed from a generative cell. And a species of this individual has adapted itself to the environment through evolution. In this paper, we propose a new method of designing neural networks using biological inspired developmental and evolutionary concept. Ontogeny of organism is embodied in cellular automata(CA) and phylogeny of species is realized by evolutionary algorithms(EAs). We call 'Evolving Cellular Automata Neural Systems' as ECANSI. The connection among cells is determined by the rule of cellular automata. In order to obtain the best neural networks in given environment, we evolve the arragemetn of initial cells. The cell, that is a neuron of neural networks, is modeled on chaotic neuron with firing or rest state like biological neuron. A final output of network is measured by frequency of firing state. The effectiveness of the proposed scheme is verified by applying it to Exclusive-OR and parity problem.

The understanding of real-world application of scientific knowledge such as the evolutionary theory has been emphasized in science curriculum. Despite this, many students and biology educators misunderstand the use and practical application of the evolution theory. The purpose of this study is to explore variables related to the understanding of practical application of evolution. Methodologically, we employed large-scale survey that examined three independent variables (major, academic year, and religion) and five dependent variables (understanding of practical application of evolution, knowledge of, interest in, and acceptance of evolution, and religiosity). Two hundred and thirty three biology pre-service teachers and 405 non-biology pre-service teachers participated in the survey. The results demonstrate that the biology teacher education program does not help in increasing the understanding of the practical application of evolution. Rather, the understanding of practical application of evolution was associated with their religion. In addition, the understanding of the practical application of evolution was associated with the acceptance of and interest in evolution. The results of this study inform the development of new biology teacher education programs to improve their understanding of practical application of the evolution theory. We also suggest further areas of research for other scientific concepts that could be used to gauge teachers' understanding of the practical application of scientific knowledge.

Many biologists and various educational associations define evolution as a unifying theme as well as a central idea in biology. In this study, teacher education programs were developed as 18-hour courses on understanding the unified role and significance of evolution in biology, and their effectiveness was tested. As factors for the program content, enhancement of the acceptance of evolution, reinforcement of the conception of evolutionary theory, and recognizing and practicing evolution as the unifying nature of evolution were considered. Hands-on activities, self- and peer-evaluation, and projects based on the small teams including frequent questioning and feedback by instructors were considered methodological factors. Six in-service biology teachers and seven pre-service teachers took part in the programs of the graduate school of H university to testing their effectiveness. They were effective in improving the acceptance of evolution, the understanding of evolutionary mechanism, the perception on the unified role of evolution. The programs also induced a positive change in self-evaluation for knowledge of evolution and perception on importance of evolution in biology. Subsequent studies on whether the changed perceptions of the teachers who participated in the programs reflect on their biology classes in secondary schools after finishing the graduate program are required.

Systematic theory, concepts, and methodology for the biological evolution have been developed while patterns and principles of the evolution have been actively studied in the past 200 years. Furthermore, they are applied to various fields such as evolutionary economics, evolutionary psychology, evolutionary linguistics, making significant progress in research. In addition, existing studies have applied main biological evolutionary models to artifacts although such methods do not fit to them. These models are also limited to generalize evolutionary patterns of artifacts because they are designed in terms of a subjective point of view of experts who know well about the artifacts. Unlike biological organisms, because artifacts are likely to reflect the imagination of the human will, it is known that the theory of biological evolution cannot be directly applied to artifacts. In this paper, beyond the individual's subjective, the aim of our research is to present evolutionary patterns of a given artifact based on peeping the idea of the public. For this, we propose a text mining approach that presents a systematic framework that can find out the evolutionary patterns of a given artifact and then visualize effectively. In particular, based on our proposal, we focus mainly on a case study of mobile phone that has emerged as an icon of innovation in recent years. We collect and analyze review posts on mobile phone available in the domestic market over the past decade, and discuss the detailed results about evolutionary patterns of the mobile phone. Moreover, this kind of task is a tedious work over a long period of time because a small number of experts carry out an extensive literature survey and summarize a huge number of materials to finally draw a diagram of evolutionary patterns of the mobile phone. However, in this work, to minimize the human efforts, we present a semi-automatic mining algorithm, and through this research we can understand how human creativity and imagination are implemented. In addition, it is a big help to predict the future trend of mobile phone in business and industries.
