As an attempt to consider what to pay attention to in science learning, this study was conducted with the aim of discussing the meaning of science learning as a heterogeneous network. As a result of theoretical investigation, the characteristics of the heterogeneous network were described in three aspects: heterogeneous composition, existence by relations, and construction and change by translation. And it was discussed that science learning also has these characteristics of heterogeneous network. Relating to what to pay attention to in science learning, it was also discussed that science learning as a heterogeneous network requires us to pay attention to the elevation of things, the concept as a punctualized heterogeneous network, and the construction and expansion of heterogeneous network with neonadeuri of 'unripe' and 'ripe'. Finally, several suggestions for the science learning were given.

과학교육의 특성상 가장 효과적인 교수 방법은 직접 실험하고, 탐구, 체험 학습을 하는 것이나 시간적, 공간적 제약, 환경 여건, 비용 등을 고려해 볼 때 항상 직접 체험 학습 환경을 제공해 주기는 어렵다. 또한 '지구과학' 영역의 학습은 교실이나 실험실에서 지도하기 어려운 문제점이 있고, 학습 내용들이 본질적으로 가지고 있는 초실험적인 내용이 많아 교수 학습과정에서 많은 어려움을 겪고 있는 실정이다. 이러한 제한점이 많은 초등학교 과학과 '지구과학' 영역에 대하여 직접 탐구하고 체험할 수 있는 환경과 가까운 멀티미디어 웹 기반 코스웨어를 설계 개발하여 이러한 어려움을 보완한다면 과학 교육의 학습 효과를 더욱 높일 수 있을 것이다. 이에 본 연구에서는 과학과의 지구과학 영역 중 기상 교육을 위한 웹 코스웨어를 설계 개발하여 수업현장에 적용해보고자 한다. 본 연구에서 제시한 웹 코스웨어 학습 프로그램은 단지 디스플레이 형식의 자료에서 벗어나 여러 가지 그림, 소리, 동영상 등의 애니메이션 자료를 제시함은 물론 아동들이 직접 컴퓨터를 조작함으로써 학습목표에 보다 쉽고 재미있게 도달할 수 있도록 제작하여 과학과 교수 학습 방법의 개선을 꾀하고, 학습자들의 과학적 사고력 발달을 도모하고자 한다.

In this case study, we investigated teaching strategies of science teacher's teaching in science museum. Two secondary science teachers who completed a teacher training course on teaching in science museums participated in this study. We conducted interviews about their perceptions on teaching in science museum and their teaching plans before teaching. Then, we observed and recorded their teaching practices in the science museum throughout one semester, and collected all of the teaching materials. The interviews were also conducted after every lessons and at the end of the semester. For the analysis of teaching strategies, we used a framework that was revised from the framework for museum practice (FMP). The analysis of results revealed that the teachers understood the significance of planning the activities in a series of pre-visit, during-visit, and post-visit, so that they structured their teaching as continuous activities, not as an one-time event. However, they showed differences in the extent of connecting the activities with the national science curriculum according to their teaching objectives. In addition, there were differences in strategies such as promoting social interaction, evoking students' curiosity and interest, providing students with choices and control, and inducing engagement and challenge depending on each teacher's perceptions and experiences on teaching in science museum. These results suggest that science teacher education for the professional development of teaching in science museum should systematically provide knowledge and experiences on teaching strategies based on appropriate perceptions on teaching in science museum.

The study aims to investigate self-regulated learning ability (SRLA) of students and analyze its relationship to their science inquiry skill and affective domain of science in middle schools in Korea. For this end, the research questions include the followings: First, what level is SRLA of middle school students? Second, how does the relationship between SRLA and science inquiry skill look like? Third, how does the relationship between SRLA and affective domain of science look like? A research method employed in the study is the survey utilizing three questionnaires: a) a questionnaire of SRLA (Jung et al., 2004); b) a questionnaire of problem finding ability of the science inquiry skill (Jung et al., 2004); and c) a questionnaire of science affective domain (Seo et al., 2008, adopted from 2006 PISA Student Questionnaire). Responses to three questionnaires by 704 students from seven middle schools in Busan, Ulsan, and Gyeongnam in Korea were analyzed. The research findings were as follows: First, mean average scores of SRLA is 3.02 (${\pm}0.63$) in 5 Likert scale (1 = strongly disagree; 5 = strongly agree). Second, students with higher scores in science inquiry skill showed significantly (p<.05) higher scores in SRLA than others. Third, boys scored higher on self-efficacy scale than girls. As students advance their grade level, their affective domain levels of science significantly (p=.048) decreases, in particular, their self-efficacy level most significantly (p=.002) decreases. Fourth, SRLA was significantly (p=.000) correlated with science inquiry skill and affective domain of science. In conclusions, it appeared that the higher SRLA level of students in middle schools is, the higher level of science inquiry skill and affective domain of science is.

The purpose of this study is to investigate the structural relationships among the attitude toward science and science motivation such as affective characteristics, and self-regulated learning strategy such as cognitive factor of science achievement. 853 middle school students residing in Seoul completed questionnaires about attitude toward science, science motivation, and self-regulated learning strategy. The sample variance-covariance matrix was analysed using AMOS 20.0, and a maximum likelihood minimization function. The results are as follows: First, attitude toward science, science motivation and self-regulated learning strategy of middle school students were all found to have a significant direct effect on science achievement. Second, attitude toward science and science motivation in middle school students has a direct effect on the self-regulated learning strategy. Third, attitude toward science in middle school students has a substantial indirect effect on science achievement mediated by their self-regulated learning strategy. Forth, science motivation in middle school students has indirect effect on science achievement mediated by their self-regulated learning strategy. Therefore, in order to improve science achievement among middle school students, teachers should consider synthetically the affective characteristics such as attitude toward science and science motivation, and cognitive factor such as self-regulated learning strategy.

The purpose of this study is to analyze activities of mentally retarded students studying science within inclusive classes from the aspect of activity sharing to investigate ways of improving their involvement in the tasks. For this study, three mentally retarded students and their peer group in inclusive classes were observed and videotaped for 12 science class sessions about forces and waves. There were many cases in which task involvement of mentally retarded students changed according to three degrees of their activity sharing: well-synchronized, delayed and estranged. When degrees of activity sharing were estranged or delayed, task involvement of the mentally retarded students faded from activeness to passiveness. When the degree of activity sharing was well-synchronized, the mentally retarded students showed interest in learning and were able to participate in science class more actively. Different patterns of activity sharing of mentally retarded students between teacher-centered activities and student-centered activities were observed. In most cases of teacher-centered activities, the monotonous pace could deprive the mentally retarded students of their chance to catch up. As a result, their delayed degrees of activity sharing were faded into estranged degrees. In many cases of student-centered activities, various pacing according to the groups or students could provide mentally retarded students with a chance to catch up, so they could be well-synchronized. In one case of teacher-centered activity, the mentally retarded students were well-synchronized with the teacher's repeated explanations and well-matched illustrations on the blackboard and textbooks. In some cases of student-centered activities, students were well-synchronized with positive relations with and appropriate intervention by other students. In conclusion, various approaches to encourage activity sharing of mentally retarded students with normal ones should be pursued to improve task involvement and academic achievement of mentally retarded students.
