The purpose of this study was to apply the instructional strategies for conceptual change prescribed by Posner et al(1982) to the astronomic content domain taught in the elementary and middle school and to analyze the characteristics of students' knowledge revealed in the test before, during and after the instruction. Also, it was to investigate the intercorrelation of cognitive levels, spatial ability and science achievement. The major findings of this study are as follows: 1. Students had a great variety of misconceptions related to the motion of the moon before the instruction, that is, the phases, the names of phases and the cause of changing phases by the moon's orbit about the earth, the moon's appearance and location at the given time, the relative positions of earth, moon and sun during a lunar eclipse, the cause that a full moon is not at the line of node once a month. In the analysis of students' responses concerning the cause of changing phases of the moon and a lunar eclipse, the results indicate that the great majority of students had rote learning rather than meaningful learning in the middle school. 2. Students' reponses during the instruction concerning the changing phases of the moon and the predictive knowledge about the motions of the earth and the moon were analyzed. 1) According to the results of the test given before and after experiment, after discussion, achievement score of the whole of subjects and groups in both preformal and formal cognitive levels appeared to increase linearly. 2) There was no statistically significant differences of achievement scores before and after experiment, after discussion between preformal group and formal group in cognitive levels. 3. Distribution of achievement scores according to the whole of subjects and groups in preformal and formal cognitive levels shows that there was a statistically significant difference between pretest and posttest. 4. Types of conceptual changes concerning the cause of changing phases of the moon that occurred from pretest to posttest were classified as accommodation, incomplete accommodation, assimilation, no change and no model. Six of the seven students starting instruction with alternative frameworks didn't sustain those alternative models throughout instruction. Five of these six students accommodated completely and the last one partially. Seventy-nine percentage of students taking instruction with fragmental models assimilated correct propositions at the end of the instruction. These results suggest that conceptual change model prescribed by Posner et al(1982) has promised the meaningful learning to students taking with fragmental models, especially in cases where students with misconception enter instruction. 5. High correlation between achievement score of simple-recall items and that of written items in pretest and posttest indicates that the higher students got the score in simple-recall items the better they also performed in written items. However, there was no statistically significant differences among cognitive levels, spatial ability and science achievement in the whole of subjects and groups according to the cognitive levels.

Prospective teachers need to have an opportunity to critically examine their initial perception with regard to effective mathematics instruction during the teacher education period. This study analyzed the perception in relation to good mathematics instruction by a total of 265 prospective teachers from four institutes for elementary teacher education using a survey. The results of this study showed that the pre-service teachers regarded learner, teaching and learning method, selection of content, and construction of curriculum as important for high-quality mathematics instruction. However, they revealed relatively low levels of agreement against the importance of instructional materials, classroom environment and atmosphere, and assessment. On the basis of teachers' perception on each element of effective mathematics instruction, this paper raises issues for discussion and includes some implications for teacher education.

In this study, the researcher aimed to increase productive reflection of pre-service elementary teachers through reflective journal writing and discussion after science peer teaching practice. 'Productive reflection' involves consideration and analysis of interrelationships among aspects of teaching including learners and learning, subject matter knowledge, assessment, and instruction. During 8 week efforts, productive reflection has increased gradually in both individual journal and class discussion. However half of individual journals didn't show productive reflection even in the final stage. This implicated that development of reflective thinking is an achievable but progressive change. By describing the progress in discussion and participants' responses on journal writing and discussion activity, this study shed light on practical ways of enhancing reflective teacher education.

지금까지의 독서교육은 교수-학습 활동과 연계되지 못한 채 별개의 것으로 인식되어 왔으며, 독서의 본질적인 측면보다는 독서자료의 제공이나 책을 다 읽고 난 후의 표현 활동에 치중하여 왔다는 문제점이 있다. 이에 본고에서는 교과학습과 독서 활동을 연계하고, 독서자료의 접근은 물론 실제 책을 읽는 인지적 활동 그리고 책을 읽고 난 다음의 표현 활동을 종합적으로 수행할 수 있는 웹 기반 독서교육 시스템을 설계, 제안하였다. 북어드벤처, 썬링크등 기존의 독서교육 시스템을 분석하여 웹 기반독서교육시스템의 요구사항을 도출하고, 이를 바탕으로 시스템을 설계, 제안하였다. 제안한 웹 기반의 독서교육시스템은 독서안내, 나의 독서수준, 책 고르기, 독서 전략, 독서표현, 독서토론 등 6개의 메뉴로 구성되어 있다.

The purpose of this study was to investigate current practices in blended instruction. In particular, the study explored (1) the types of instructional delivery methods, technologies, and instructional components, (2) the reasons why faculty apply blend instruction, and (3) the advantages and challenges in delivering blended instruction. This study focused on the practices in the Universities that have the extensive doctoral research programs classified by the Carnegie Foundations. The survey was performed with the sample of faculty from 30 universities and the survey data included 133 faculties out of the total 1,000 randomly selected faculty members. Of the 133 responses, 111 (77.7%) participants had certain degree of experience, while 17 faculty (or instructors) (13.3%) did not have any practice with blended instruction. The most common instructional delivery format in the participating universities was blended instruction that added supplementary online instructional components in the class. Online Course Management Systems (CMS) and multimedia presentation tools were common technology for course delivery, and "discussion" was the most general instructional activity for the class. The participating faculty often preferred the blended format since it provides students and faculty with convenience, flexibility, active engagement, efficiency in using resource materials, and a feeling of connection between/among students and instructor. Benefits to the class were availability of more authentic experience and diverse curricular materials, and the instructional format that meets the needs of remediation and enhancement of students. This study addressed not only advantages and challenges of blended instruction, but also suggestions based on the comments by the participating faculty.

WWW라는 인터넷 서비스로 인해, 네트워크 인프라는 폭발적으로 성장되었고 웹기반 기술은 상상을 초월하는 속도로 발전을 이루어 왔다. 그 기술은 사회 각분야에 많은 영향을 미쳤고, 교육분야도 예외가 아닐 수 없다. 한편 요즘 교육현장에서는 토론이 가지는 장점으로 인해 구성주의적 관점과 수행평가 측면에서 더욱 강조되고 있는 현실이다. 그러나 원격교육 차원에서 웹기반 토론 수업은 매체를 통한 상호작용으로 인해 면대면 토론이 가지는 특성과 많은 차이가 있다. 따라서 본 연구에서는 실제 웹기반 토론 수업을 할 때의 고려점을 살펴보고, 사용되는 지원 시스템의 개발시 고려 요소와 개발 방안을 살펴보기로 한다.

A new way of teaching on the Internet can be called Web Based Instruction (WBI). WBI goes far above and beyond teaching in the school. It will have an impact on overall educational activity that will dramatically change many existing educational processes and persuade most teachers to change their conventional teaching methods. The main purposes of this research were to make a comparative study of academic achievement between expository lecture and web-based instruction, and to identify the difference in academic achievement of learning tasks in pre- and post- experiments of WBI. The conclusions of this study were as follows. First. there are no differences in academic achievement between expository lecture and teacher- directed web based instruction. Second, there are no differences in academic achievement between expository lecture and teacher-assisted web based instruction. Third, there is difference in academic achievement between teacher-assisted web based instruction and teacher-directed web based instruction. Fourth, there are no differences in academic achievement of reading tasks in pre- or post- experiments of teacher-directed web based instruction. On the basis of the research results and discussion, we finally present a Web-Application-Model (WAM) to encourage the usage of Internet as a useful teaching channel.

이 연구에서는 초등학교 과학과 수업 분석을 통하여 초등 과학 수업의 개선을 위한 시사점을 도출해 내고자 하였다. 교수-학습 방법에 중점을 두어 7개의 수업 사례를 관찰하고 분석하였다. 수업 관찰 결과, 초등학교 과학 수업에서는 실험이나 활동을 한 뒤에 정리하고 토의할 시간이 부족하고 교사의 적절한 안내가 이루어지지 않아서 실험이나 활동 결과를 학습목표와 관련지어 이해하는 데 어려움이 있었다. 그리고 관찰 관점이나 실험 방법에 대한 안내가 부족하였고, 실험 기구를 올바르게 사용하는 방법과 유의할 점, 실험 기구를 사용하는 이유 등에 대한 안내가 충분히 이루어지지 않았다. 이러한 문제점을 개선하기 위하여 관찰 관점, 실험 기구의 용도와 사용법 등에 대한 교사의 안내 활동을 강화하고 실험 결과에 대한 논의가 충분히 이루어지도록 하기 위한 방안을 모색할 필요가 있다.
