과학 대화를 이용하는 수업에서 교사와 학생이 겪는 어려움 및 대화 능력의 변화,발전에 대한 사례 연구 = A Case Study of the Difficulties of Teacher and Students in Using the Science Talk, and the Change and Improvement of Their Ability of Talking about Science

다국어 초록 (Multilingual Abstract)

The purpose of this study is to investigate the use of the science talk in a second grade science classroom in U. S. This case study examined a prospective elementary teacher`s attitude to the science instruction during her preparation for science lead teaching based on the use of the science talk. This study also described the teacher`s and students` difficulties as well as the developmental process appeared in their strenuous efforts of employing the science talk to their science classroom. For this study a prospective elementary teacher was selected while she was doing her internship in the 5th year of her teacher education program at Michigan State University and was teaching 17 lessons of the food for the plants unit for an elementary science classroom of 18 second graders. The multiple sources of data included researchers` participatory field notes and video/audio-recordings acquired from her classroom teaching and students` classroom activities during 8 weeks. The interview data were gathered, and all of the audio-taped interview data were fully transcribed. Analysis of the data showed that in the beginning of the adoption of the science talk, both teacher and students showed difficulties in managing and developing the effective science talk. At the beginning, the teacher revealed the inefficient management skills of the science talk. As a result, the students did not make a good scientific discussion and argument! not providing their own scientific evidence. As the science classes were moved on, however, both teacher and students were able to make significant progress on their scientific discussion and discourses through their strenuous efforts to use on-going science talks. Finally, the students showed not only the ability to deeply think about and discuss the particular science topics, but also the overall improvement of communicating sharing, and discussing of their science ideas based on scientific evidence and reasoning.
