The rectnt studies on the learning of the scientific concepts have suggested that most students have misconceptions related to the contents to be learned and that those misconceptions exert their influences on the subsequent learning of the content Those facts necessitate the identification of the misconceptions before the instructions and the preparation of the instructional materials based on those misconceptions identified. Several studies also revealed that such biological areas as cell division, reproduction and fertilization were ranked among the most difficult areas for high school students to learn. Therefore, this study had its triple objectives as follows: (1) Identification of misconceptions in such areas as cell division, reproduction and fertilization. (2) Investigation of the current high school biology textbook I's as the sources of those misconceptions. (3) Development of teaching materials based on the misconceptions identified and the problems in the textbooks analyzed. This study identified several misconceptions held by high school students of biological concepts related to the conceptual areas of life-continuity, and found the problems in learning of the high school biology textbooks. Based on the misconceptions and the problems, a teaching/learning model and its content material were developed at the final course of this study.

본 논문의 목적은 Computational Thinking(CT) 교육에서의 학습자 평가를 위한 방안으로 학습자가 제작한 프로젝트의 코드를 분석하는 방법을 제안한다. 최근 초중등 SW교육에서는 블록형 프로그래밍 도구를 활용한 교육이 이루지고 있으므로, 학생들의 산출물인 스크래치 프로젝트의 코드를 분석하여 CT 개념 습득과 학습자의 수준을 평가하는 방안을 모색하였다. 초보학습자 45명의 프로젝트를 분석한 결과 초보학습자들의 잘못된 습관에 대한 패턴이 나타났으며 CT 개념 학습을 코드의 패턴에 의해 평가할 수 있다는 것을 검증하였다. 학습자의 수준이 높을수록 논리적 사고, 동기화, 플로우 제어, 데이터 표현의 요소 점수가 높게 나타났다. 본 연구의 결과는 초중등 SW 교육에서 CT 개념 학습에 대한 평가를 위해 활용할 수 있다.

본 연구에서는 다중 비유의 사용 방식이 중학생들의 과학 개념 이해에 미치는 효과를 조사하였다. 7학년 학생 127명에게 다중 비유의 사용 방식(비유물의 개수, 비유물과 목표물의 대응 회수, 비유물간 유사성 비교)이 다른 네 가지 유형의 비유 학습 교재 중 하나를 무선 배포하여 읽게 한 후, 개념 검사를 실시하였다. 분석 결과, 비유물이나 대응 과정을 2번 사용하는 것은 과학 개념의 회상 및 응용에 유의미한 영향을 주지 않았다. 그러나 비유물간의 유사성 비교는 과학 개념 응용에서 유의미한 효과가 있었다. 이에 대한 교육학적 함의를 논의하였다.

We analyzed and compared factors such as changes in the degree of difficulty of concepts presented in Chemistry I textbook, changes in class types (non-face-to-face, face-to-face), etc. on academic achievement by level (upper, middle, and lower). Students from A high school in Gyeongsangnam-do were selected for the subjects of the study. As a result of analyzing the change in the degree of difficulty of concepts, the total score of chemistry I combined by non-face-to-face and face-to-face classes during the second semester was lower than that of the first semester. As a result of analyzing the impact of factors such as changes in conceptual difficulty, changes in class types, etc. on academic achievement by level, students' grades at the 'lower level' by non-face-to-face classes were lower than those by face-to-face classes. In particular, at the lower level of the second semester, there was a large difference in grades between non-face-to-face and face-to-face classes. In the results of these studies, it was found that instructors' active feedback is important to identify difficulties in understanding learning contents for students with low levels of academic achievement and improve them at the same time.

Objectives: Many female college students today control their lifestyle not for the purpose to promote their health but to maintain slender figures. The purpose of this study was to explore and describe the lifestyle of female college students from their own perspectives. Methods: Data was collected through interviews of 25 female students and was analyzed by using Colaizzi's descriptive phenomenology(1978). The phenomenon of interest was described, followed by collecting participants' descriptions of the phenomenon and extracting concepts from significant statements. These concepts were then organized into thematic clusters, followed by exhaustive descriptions into which data was applied to extract the final categories. Results: The results were deduced into 226 re-statements, 38 constructed meanings, 23 themes, 11 theme clusters, and 5 categories. The five categories include 'Increased interest in physical health,' 'Selective dietary patterns influenced by lifestyle,' 'Lifestyle formed by social adaptation,' 'Health complications caused by self-body images,' 'Engages in healthy dietary behavior'. Conclusion: This study described the experiences of female college students' lifestyles after completing a course in health promotion. These findings have important implications on health education for college students which should be considered in developing health education programs in preparation for adult years of life.

Four science concepts were selected from high school science textbook to investigate the differences in priorities of students knowledge activated during solving earth science problems in laboratory and earth science environmental contexts. Two items, one for laboratory context and the other for earth environmental context, were developed for earth selected concept The subjects were constituted of 192 students in 11th grade and 196 in 12th grade in one senior high school. Students' responses were categorized using graph models and analyzed in terms of 'Common Activated Knowledge'(CAK). and 'Specific Activated Knowledge'(SAK) across students' cognitive frames, grades, and sex. As contextual differences of the problems increased, context effects in priorities of CAK were reported in favor of laboratory context, on the contrary those of SAK in favor of earth environmental context. Context effects were reported across cognitive frames, especially students with laboratory cognitive frames showed more significant context effects than others. Lower graders and girls showed relatively large context effects. The results of this study showed that science concepts learned in a laboratory context are not easily transferred to earth environmental context. Therefore, special instructional strategies should be developed to overcome the context effect s according to activated knowledges with high priorities in laboratory and earth environmental context.

This study, to effectively teach the concepts, principles and problem solving ability of the 2nd graders' learning of numbers and operations, offers realistic problem situation and focuses on the learning based on 'mathematization', one of the most important principles of RME (Realistic Mathematics Education) which is the mathematics education trend of Netherlands influenced by Freudenthal's theory. The instruction is applied to forty-one students of the 2nd grader for six weeks in twelve series in an elementary school, located in Seoul. To investigate the effects of the mathematising experience instruction for improving mathematical abilities, the group takes tests before and after the instruction. Also the qualitative analysis on the students' mathematising aspects through students' output at the instruction process is taken into account to evaluate the instruction's effects. The result shows that the mathematising experience instruction for improving mathematical abilities is proved to improve students' understanding of mathematical concepts and principles and their problem solving ability in learning numbers and operations after carrying out this instruction. Also the result indicates that students' mathematising aspects are mostly horizontal and vertical mathematization.
