이 연구의 목적은 중학교 과학 수업에서 교사와 학생간의 언어적 상호작용이 실제로 어떻게 이루어지고 있는지를 관찰ㆍ분석하여 이에 대한 특징을 추출함으로써 과학 수업에서 교사와 학생간의 언어적 상호작용에 대한 기초 자료를 제공하는데 있다. 이를 위해 수업 분석 준거를 개발하였으며, 8명의 과학 교사의 수업 12차시를 관찰 및 녹화하였으며, 교사와의 면담을 실시하였다. 수업 분석 결과, 관찰한 과학 수업에서 교사와 학생간의 언어적 상호작용은 주로 교사의 단순 확인/기억 질문, 학생의 단답형 응답, 교사의 즉각적 피드백이 주를 이루었다. 교사가 사고 질문을 하고 지연 피드백을 부여 하는 경우 학생들이 자신의 생각을 드러내고 이를 기반으로 사고를 진전시켜 나갈 수 있었으나 이러한 사례는 그 수가 상당히 적었다. 교사들은 학생들의 사고를 유발하고 이를 진전시키기 위한 노력보다는 수업 내용을 논리적 흐름에 맞추어 체계적으로 제시하는 것에 더 큰 중점을 두는 경향이 있었다. 또한 관찰한 수업에서 교사가 시범 실험, 모형 혹은 실물 수업자료 등을 활용할 때 보다 많은 수의 학생들이 적극적으로 수업에 참여하여 자신의 생각을 드러내었으나 교사가 학생들의 생각을 바탕으로 학생들의 사고과정을 진전시켜 나가는 과정을 도모하지 않음으로써 학생들의 사고과정을 단절시키는 경우가 많았다. 따라서 수업 활동과 수업 자료 활용이 효과를 거두기 위해서는 각각의 활용에 있어서 학생들과 구체적으로 어떠한 상호 작용을 형성해야 하는지에 대해 연구가 이루어져야하며, 또한 교사는 교사의 질문이나 피드백이 학생들의 학습에 중요한 역할을 함을 인식해야 한다. The purpose of this study is to analyze verbal interaction between teachers and students in order to collect qualitative data on the characteristics of the interaction to enhance teaching efficacy. Total of 12 classes of eight science teachers were observed and were interviewed. The classes were video taped and all the verbal interactions were transcribed. The transcribed content and interviews were further analyzed to draw any conclusions on the verbal interaction between teachers and students. Analysis criteria for the data on the class and interview were developed based on the literature review and applied to analyze the collected content. The analyzed data showed that verbal interactions composed of confirmation questions for memorization, students' short responses and teacher's immediate feedbacks. The results of the study also suggested that there needs to be further studies on the interactional techniques for teacher in utilizing the class materials and activities. The teachers should acknowledge the importance of the questions and feedbacks of teachers for students to stimulate their sound learning through literatures.

팔당호의 생태학적 환경요인의 계절적인 변화를 분석하므로서 이것으로 인한 식물성 플랑크톤의 연관성을 고찰과 함께 오염과정을 파악하여 수질오염의 예방의 기초자료를 얻고자 본 실험을 수행하였다. 1994년 4월부터 1995년 10월까지 계절별로 3개 지점에서 시료를 채취하여 표층부와 저층부의 수질을 분석하였다 용존산소(DO)와 pH는 각각 7.0-11.6 ㎎/ℓ와 6.9-8.9의 범위이었으며 COD와 BOD농도는 각각 1.6-4.8 ㎎/ℓ와 0.8-2.9 ㎎/ℓ이었으며,SS는 1.8-8.6 ㎎/ℓ의 농도차를 보여 주었다. 또한 NH₃-N와 PO₄-P의 농도는 각각 0.161-0.478 ㎎/ℓ와 0.003-0.073 ㎎/ℓ이었다. 표층의 chlorophyll a의 농도는 낮게는 북한강 유입부위인 12.3 ㎎/ℓ로부터 가장 높은 경안천 유입부위 23.8 ㎎/ℓ의 범위를 보여주고 있다. pH,전도도, COD, BOD, SS ,총인, chlorophyll a의 농도는 하계절에 가장 높았으며 이 결과로 미루어 보아 하계절에는 하천에 오염물질이 가장 많이 유입되는 것으로 추정된다. Station별로 조사한 결과 이들의 농도는 경안천 하류인 St. 3가 남한강 하류인 St. 2이나 댐지역의 St. 4보다 높은 결과를 보여 주었으므로 경안천 상류에서 오염원이 가장 많이 유입되는 것으로 추정된다. 아울러 종속영양세균의 분포도 경안천이 다른 지역보다 가장 높게 나타났다. Seasonal variation of water quality was examined in the reservoir, lake Paldang on Han River, the inlet stations from three rivers, North Han River, South Han liver, Kyung-An stream, and the station of dam area of the lake. Water samples were collected bimonthly from surface and bottom layers at four different stations of the lake Paldang from April 1993 to August 1994. With respect to the seasonal variation, pH, conductivity, and concentrations of COD, BOD, SS, total phosphorus, and chlorophyll a were higher in summer compared with those of autumn or other seasons, while concentrations of DO, NH₃-N, and PO₄-P were increased in winter. Concentrations of COD, BOD, chlorophyll a, total nitrogen and phosphorus were the highest at the station of Kyung-An stream rather than those of other three stations. The average concentrations of chlorophyll a surface water were from 12.3 ㎎/ℓ at North Han River to 23.8 ㎎/ℓ at Kyung-An stream. Heterotrophic bacterial distribution showed higher at the station of Kyung-An steam than those of South Han River and the dam station of the lake.

Investigation was made on how the relatively long Cheogori with side-cut formed a Dangeui, a style indigenous to Korea, through what kind of modification according to the current of the times and following is the summary of the result. From Koryo dynasty, side-cut Cheogori started to be given and this resulted from that the length of Cheogori began to be shortened, I think. Then the width seemed to be relatively wide. Since then, gradually the length of Cheogori became long and hem part of front and rear was changed to curvilnear style as the width gradually got narrow and even the cut of the side-line was extended up to the armhole part. This has been called as Cheogori, Tangcheogori and before one knows when, the name was changed to Dangeui. Regarding the name, research on the terms needs to be made again hereafter. Accordingly it can be understood that side-open coat was made among the Korean traditional Cheogori by side-open and according to the current of the times, open of the side-line got deep as its width became narrow and straight-line was changed to curved line. Accordingly both edges of the hem line came up to the inside of the collar and formed present curvilinear style. The style of collar was changed to square type collar and half-square type collar and Dangko collar in order, whcih formed and almost same mode as the collar change of other kind of coat.

For this study middle school science instructions were observed and analyzed. It has done how the science instructions were interacted to improve students' learning. In the middle school science instruction, and in the science instruction process, specific characters of the teachers and students' interaction were found out. This study is for drawing the characters of the interaction between teachers and students' and facilitating the desirable instructions. For this study, four teachers of coeducationals in Kyung-ki province were selected at discretion. then each teacher's instruction was recorded twice and was copied all the contents of observation. The aspects of instructional contents, instructional methods and instructional circumstances are considered on this study. How teachers and students are interacted in science instruction was analyzed. The conclusions are as follows. In the aspect of instructional contents, there are several good ways to interact. First, reorganizinge the contents of textbooks is much better than just teaching original contents of the textbook. Second, connecting science with students' ordinary life is also a good way. Finally, teachers' using thoughts ,understandings and meta questions to read students' responds make strong interaction. In the aspect of instructional method, using audio-visual material in instruction is better than lecture style one. Because the former can make students participate in instruction positively, the interaction strongly occurs. In the aspect of instructional circumstances, the instruction which contributes to democratic atmosphere showed stronger interaction than opposite case because such instruction respected students' opinion in maximum.

The purpose of this study was to investigate the effectiveness of Learning Cycle approach to change the concept of density. The results of the study were as follows: 1) Students already had various types of preconception related to density before formal learning. These preconceptions mostly differ from scientific concepts. 2) Male students were much better than female ones in the development of scientific concepts before formal learning. These differences were found statistically significant(P<0.01). 3) The higher the cognitive level of the students, the better the development of scientific concepts. 4) In the change of preconceptions to scientific concepts by treatment, there was significant difference between control group and experimental group at the 0.05 level. It was found that Learning Cycle approaches were more effective than traditional approaches in acquiring the concept of density. 5) It was found that there was no significant difference on the retention level of the concept of density between control group and experimental group.

This study aims at emphasizing the importance of the paternal involvement in the social milieu of the infant. It is generally said that the paternal role, which we have considered in traditional contexts, is getting into change as time passes and social trends change, In this connection, we would like to make it clear, by using the numerous precedent studies in this field, that the experience in the infant-father interrelations/interactions contributes to the intellectual and societal development of the infant. By doing so, therefore, we would able to prepare the motivation to further the study on the infant-father relations which have long been overlooked in Korea. The results of the study can be summarized as follows: 1. The infant-father attachment development is influenced by the paternal early involvement in bringing-up(caregiving), preference, and sensitivity ; so as to enhance their ties, the earthier the contacts come, the more effective they become. 2. In the infant-father contacts, the infant preferred his/her father as the primary partner of the play, and the interactions through the infant-father play contributed to enhance the infant's intellectual and societal development. with the above results that were accumulated throught precedent studies, Ie wish to propose some points for the further studies in the field : First to consider the environmental variables of this family support-system which has great impacts on the infant-father interactions and second to grop for logitudinal study programs by adapting such various techniques as natural and operative experiments and investigations.
