Analysis of communication between the student who played a role as gatekeeper and the student who Waved a role as end user in the science class

本研究是在小学、初中科学课的研究活动中进行的实践性研究。在这项研究中，我们的目的是通过分析学生的交流，澄清作为看门人的学生和作为最终用户的学生的对话的定性内容。小学的一项研究是四年级科学B课的“物体的体积和温度”单元。本单元于2007年6月至7月实习。我们用录音机和摄像机记录了课堂的情况。我们分析了录音中老师和学生的对话和行为。结果得到如下点：在扮演看门人角色的学习者和扮演最终用户角色的学生之间，一个学生听到对方的声音的现象自然出现。此外，我在学生之间相互教导的现象自然出现。初中的调查对象是二年级科学第二单元“植物的世界”田野的小单元《一片叶子的结构与作品》。这是在2007年8月至9月的实践。我们用录音机和摄像机记录了课堂的情况。我们分析了录音中老师和学生的对话和行为。结果得到如下点：很多同学离开了，去找其他同学互相交换信息，听不懂的互相教的动作自然发生了。

This study is a practical study in the research activity of the science class of the elementary and junior high school. In this research, we were aimed at clarifying qualitative contents of the conversation of the student who played a role as gatekeeper and the student who played a role as end user by analyzing communication by students.A study in the elementary school is unit "a volume and temperature of the object" of the fourth grade science B division. This unit was practiced for from June to July in 2007. We recorded the state of the class with a voice recorder and a video camera. And we analyzed conversations and actions of a teacher and the students provided from the recording. As a result, the following point was obtained. The phenomenon that a student heard each other among the learners who played the role of gatekeeper and the student who played a role as end user appeared naturally. In addition, the phenomenon that I taught each other between students appeared naturally.The investigation object of the junior high school was small unit "a structure and a work of the leaf' of the field of the second unit "world of the plant" of the second grade science. This was practiced for from August to September in 2007. We recorded the state of the class with a voice recorder and a video camera. And we analyzed conversations and actions of a teacher and the students provided from the recording. As a result, the following point was obtained.
