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 paper attempts to explore the universal foundation on which the discourses on the validity criteria in qualitative research should be based, and further discuss in depth the scope and direction of an adequate validity criterion in qualitative research by critical examination of previous discourses. To establish the foundation for qualitative research, first of all, the concept of quality and qualitative paradigm were examined in terms of ontology and epistemology, especially focused on the works carried out by Aristotle, Kenneth and Boyd. Secondly, the earlier studies on the validity of qualitative research were critically reviewed in terms of the theoretical findings on the concept of quality and qualitative paradigm. The major results include the following: First, the true content of quality is defined as the 'what-ness' or essence of things perceived by subjects, and qualitative paradigm as adequate framework for qualitative research is comprised of two intrinsic modes: one is the mode of awareness and the other is that of expression. Second, qualitative researchers are able to reach to the higher level of validity by considering not only the subjectivity and the originality but also the sociality in drawing a conclusion through qualitative perception. Third, the trend of previous validity discourses can be firmly summarized as the effort to overcome the effect of quantitative research and acquire the true identity for qualitative research, which is subjectivity, and as the quest to compromise the tension between subjectivity and sociality. Finally, based on the findings, several research topics are suggested. For example, the more attention should be paid to the area of the expression of qualitative awareness as a way of overcome the tension between subjectivity and publicness.

The purpose of this study was to analyze the differences in perception levels of goals and concepts of physical education by the body image and gender of middle school students. Among 461 middle students randomly selected by a multistaged cluster sampling technique, 433 students(boys 267, girls 166) filled out questionnaires consisted of Figure Rating Scale and modified ones. To know the differences in the perception levels of goal and concept of physical education by sex, t-test was utilized. In order to find out the differences in the perception levels of goal and concept of physical education by body image, ANOVA was performed using the SPSS Windows 12.0. The results of this study revealed that boys had higher level of goal and concept of physical education than girls. Second, middle school students classified into normal body image was higher level of goal and concept of physical education that other body images such as very thin, thin, very obese, and obese ones. The results of this study indicated that curriculum of physical education focused on fragmentation of health, psychomotor, cognitive, affective, leisure, holistic human should make girls understand thoroughly and deeply goals and concepts of physical education and ideal body image.

This study was to promote meaning ways of leaning and observe the influence of concept maps on middle school students' conceptual formation with regards to the topic of the 'sea water'. Concept map is one way to examine a leaner's conceptual formation process. The subjects of this study consisted of four classes within the first grade students of a Busan middle school, which were divided into two groups: the experimental group which applied concept map teaching and the ordinary teaching group. This study was carried out before and after class, examining the science leaning achievement, self-directed leaning characteristics, and awareness change on the concept maps. The result of this study was as follows: First, the leaning achievement of middle school students was positively affected by the use of concept maps. Second, the teaching method with concept map was more effective self-directed leaning characteristics compared to the ordinary one. Third, concept map teaching was a positive reaction to conceptual formation.

The goal of this study is to examine the perceptions of pre-service teachers that directly affect the concepts and ways of the consideration of Earth systems by students studying the water cycle. A concept sketch method was applied to a survey involving 131 pre-service teachers. The survey was designed to analyze the perception of subordinate concepts of Earth systems from the applied components of the water cycle process and to code the applied concepts with components of the water cycle to the subordinate concepts of Earth systems that were the Hydrosphere, the Atmosphere, the Geosphere, and the Biosphere. The survey was designed to examine the perception of the water cycle from the perspective of Earth systems. The recognition by pre-service students was largely confined to components of the atmosphere and the hydrosphere. With regard to the water cycle process, all subjects surveyed recognized precipitation, and most of those expressed recognition of evaporation and condensation. Many of them recognized the surface flow, while they scarcely expressed knowledge of the underground flow.

This study investigated the effects of computer-assisted instruction adapting to the level of students' conceptual understanding upon students' conceptual understanding, retention of conceptions, learning motivation, and perception about computer-assisted instruction in concept learning. 94 seventh grade students from a coed middle school in Seoul were randomly assigned to control, CAI, adaptive CAI groups, and were taught about 'motion of molecules' for 7 class periods. Two-way ANCOVA results revealed that the scores of a conception test and a learning motivation test for the adaptive CAI group were significantly higher than those for the control group. The scores of a retention test of conceptions for the adaptive CAI group were significantly higher than those for other two groups. There were no significant interactions between the instruction and the level of previous achievement in the scores of the conception test, the learning motivation test, and the retention test of conceptions. The perception about computer-assisted instruction for the students of the adaptive CAI group were more positive than those for the students of the CAI group.

세계화가 사회적 불평등을 심화시키고 있지만 이에 대처하는 개별 국가의 능력은 오히려 약화되고 있으며, 그 결과 노인인구층의 복지여건이 악화되고 있다는 것이 종래의 일반적인 인식이다. 본 논문은 이러한 일반적 인식을 재검토하는데 목적이 있다. 검토작업은 다음 네가지 영역에서 이뤄진다. 첫째, 세계화에 대한 상이한 개념정의와 시각을 검토한다. 여기에는 노령층에 대한 복지급여를 잔여적 급여로 전환시키는데 있어 핵심적 역할을 행하고 있는 주요 국제기구의 활동을 중점 논의한다. 둘째, 세계화가 개별 국가에 미치는 영향이 일률적이라는 시각을 재검토하기 위해 세계화에 대해 서로 다르게 반응한 미국과 유럽방식을 비교한다. 셋째, 세계화가 노령화 정책에 미치는 영향에 대해 논의한다. 넷째, '사회적 삶의질'이란 개념을 통해 노인계층의 복지수준은 경제적 성장보다 사회적 급여에 더 큰 영향을 받게 됨을 보여 주고자 한다.

지금까지의 후처리기법은 문장의 의미 정보를 사용하지 않고 대부분 단어만을 생각하기 때문에 잘못 쓰여지거나 인식된 단어라도 사전에 있으면 그대로 받아들이게 된다. 따라서 본 논문에서는 단어로서 구성이 되지 않는 문자열 뿐만 아니라 의미적으로 잘못 사용된 단어까지도 교정해 줄 수 있는 후처리기법을 제시한다. 제시되는 후처리기법은 문장의 의미론 개념그래프로 표현하여 문장에 쓰여진 각 단어가 문장 내에서 의미적으로 유용한지를 밝혀 낼 수 있도록 한다.
