Elementary students' behaviors classifying leaves have been analyzed according to the material types provided for the classification class. 199 sixth grade students were participated in the task classifying the leaves of various plants for the research. The three types of materials provided to them for the class were real leaves, photos of the leaves and explanation cards including the photos of leaves. One of the research findings was that the only material made students handle in the observed behaviors was the real leave of the material types given as classifying. Three were differences between groups in the time required and the number of using criteria for the class. The numbers of criteria had been applied to analyzing their behaviors as classifying the real leaves which were less than those with photo materials. The amount of taken time to classify the real leaves and photo materials were less than those of another material. Finally, the contents of criteria did not differ between groups except appearing properties presented to the task with photo and explanation materials. It is expected that the research can be contributed for elementary school teachers and for curriculum developers to choose appropriate instructional materials as constructing curriculum contents for elementary science to make elementary school students acquire classifying skill in science classes.

본 연구에서는 이차곡선 지도 방안으로써 수작업 교구인 Wax-paper를 이용한 활동과 공학도구인 GeoGebra를 이용한 활동에 대한 예비 수학교사들의 인식을 조사하였다. 수도권 소재의 한 사범대학 수학교육과 학부생 20명을 대상으로 이차곡선에 대한 교구와 공학도구 활용 수업을 진행한 후, 두 가지 수업 방법에 대한 인식 설문조사를 시행하였다. 본 연구 결과에 따르면, 예비 수학교사들은 이차곡선 학습 및 지도에서 전반적으로 공학도구의 활용을 선호했으며, 공학도구의 활용이 시각화를 통해 직관적 사고에 도움이 되며, 다양한 수학적 성질 탐구를 가능하게 함으로써 개념 이해와 흥미 유발에 도움을 준다고 생각하였다. 그러나 학생 또는 교사의 미숙한 공학도구 사용에 대한 우려를 지속적으로 나타냈으며, 예비 수학교사들이 인식한 교구와 공학도구 활용의 장단점은 상호보완적이었다. 이와 같은 연구 결과를 토대로 수학수업에서 각 교구와 공학도구가 가진 특성에 맞게 상호보완적으로 활용하길 제안하며, 학생 또는 교사의 공학도구 사용 능력에 영향을 받지 않는 수업자료의 개발 및 보급이 필요하다는 시사점을 제시한다.

The spreadsheet Microsoft Excel is the most widely used mathematical tool in today's workplace. Moreover, it is also an outstanding means for developing a surprisingly wide range of creative and innovative educational uses within such areas as mathematical modeling, visualization, and instruction. The spreadsheet's format provides us with a tool that closely parallels the way in which we naturally carry out problem solving, while the spreadsheet creation process itself illuminates the underlying mathematical concepts. In addition, the spreadsheet's visual layout allows us to introduce a broad variety of challenging and interesting topics, and to design creative demonstrations through eye-catching animated graphics. The material presented comes from actual classroom mathematics teaching experience in both industrially advanced and developing nations. A series of highly visual interactive illustrations from mathematics, the natural and social sciences, computing, engineering, and the arts provide a number of usable examples. The material discussed is applicable at diverse levels, ranging from schools and universities through adult education and in-service teacher development programs.

The purpose of this study was to develop the instructional model and teaching material to change the middle school students'conceptions of electric current into the scientific ones and to investigate the effects of the model in actual classrooms. We identified the students' ideas and their misunderstanding about the concept of eIectic current through reviewing the literatures and our in this study. Based on the above results, we developed the instructional model and designed the teaching sequence and prepare the learning materials about the unit of the electric current in middle school Our instructional model was based on 'learning cycle' developed by Lawson, but the new stage called "exploration through qualitative questions" to elicit the students' own conceptions was inserted to it. To investigate the effects or the new teaching model, the pre- and post-test using the POE type were administered to experimental group(52 students) taught with learning cycles and control group(52 students) taught with traditional styles. The results are as follows; 1) The rates of correct. predictions was varying according to the kinds of problems. And the rates of the correct. reasons of their predictions were lower than those of the predictions. 2) The mean scores of the post-test of both groups were significantly higher than those of the pre-test. We could not find statistically significant difference in theme an score between experimental group and control group after implementation of the model. But the experimental group gained higher scores than those of the control group on two problem. Therefore, although we cannot show the prominent effects of our teaching model based on learning cycles, there are some effects of our model on changing the middle school students' conceptions of electric current.

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.

The goals of this study is to analyze develop the materials which help students develop spatial sense in elementary school and to investigate its effects. To accomplish those goals, the 7th National Curriculum was analyzed to identify the contents of spatial sense. After analyzing the 7th National Curriculum, the principle for developing the teaching aids focusing the realization of the contents in the spatial sense was set up. And then various teaching materials which can enhance students' spatial sense was developed. It is consist of 17 kinds of concretely operating materials, 7 kinds of tangram papers, one web-material. To verify the effect of the materials, surveyed the usability of the materials and two classes was selected and tests were administered before and after the treatment. Through this application, several conclusion were drawn. First, a survey result says that teachers thought materials developed would be effective in developing spatial sense. Second, the materials developed were effective to develop spatial sense. The score gained by the experiment group after the treatment was statistically meaningfully higher than the control group. This means that the materials developed helped children to develop spatial sense.

This study developed and evaluated a Seoul National University literacy program for multicultural family children (SNU-LPMFC). The program was developed to enhance Korean language ability for children from multicultural backgrounds. The characteristics of this program were education using fairy tales and nursery rhymes, individual education from home visiting teacher, and parent participation education for effective children's learning support. The effectiveness of this program was examined based on 54 young children and their mothers (34 in the experimental group and 20 in the control group). To examine the effect of SNU-LPMFC, we assessed children's literacy ability as pre-tests and post-tests as well as interviewed the home visiting teachers. After 8 weeks' field application, the experimental group exhibited higher scores than the control group in total language ability and phonology. Home visiting teachers highly praised the effectiveness of the program as the children showed a higher level of interest and attention. SNU-LPMFC was shown to be an effective program to improve multicultural family children's literacy. Implications for research and practice were discussed along with the main results of this study. This study extends the limitations of existing language education programs with uniform teaching methods, configured a customized education approach for children from multicultural families and helps develop concrete teaching material that validated its effectiveness.
