Design for Learning environment using ICT in Science Education

在本研究中，为了获得科学教育中利用信息通信网络设计学习环境的相关知识，本研究进行了以下两方面的研究。我们利用信息通信网络或计算机对课堂进行了现场参与观察，探讨了信息通信网络或计算机在科学教育中使用的问题。我们开发了一个概念映射软件，作为设计理想学习环境的一个例子。该软件支持想法的外化，对思维过程的反思，以及在协作制作概念图期间与自己和他人的对话。本软件的特色功能包括：(1)复制：软件自动保存概念图的制作过程，学习者可以随时复制，甚至可以在制作过程中复制。(2)修订：学习者可以通过将其撤消到生产过程中的任何想要的点，并对概念图进行修订。(3)协作制作：学习者可以在连接到同一网络的几台计算机上与共享同一屏幕的其他人合作制作概念图。针对该软件的使用感觉、操作易用性、协同生产的实现、协同生产过程复制的实现、协同生产的有效性、复制和修改功能以及课堂在学校的可用性等问题，要求小学教师和学生填写书面问卷。

In this research, in order to acquire the knowledge about the design of learning environment using the information communication network in science education, the following two researches were done.1. We did participating observation of the spot for the lesson using the information communication network or the computer of an and problems of use of the information communication network or a computer in science education.2. We developed a software for concept mapping as an example of one thing of the design of desirable learning environment. The software supports the externalization of ideas, reflection on thinking processes, and dialogues with oneself and with others during the collaborative production of a concept map. The characteristic functions of this software include the following :(1) Reproduction : the software automatically save the concept map production process, arid the learner can reproduce it at any time, even in the middle of the process. (2) Revision : the learner can return to any desired point in the production process by undoing it up to that point and revise the concept map. (3) Collaborative production : the learner can produce a concept map in collaboration with others sharing the same screen on several computers linked to the same network.Elementary school teachers and students were asked to respond on a written questionnaire sheet to questions about this software, in terms of feel of use, ease of operation, realization of collaborative production, realization of collaborative production process reproduction, effectiveness of collaborative production, reproduction and revision functions, and in-class usability at school.
