Development and assessment of participatory type software for teaching material aiming training of competence of science

本研究的目的是开发一个支持儿童建构科学概念和模型的计算机软件，并利用该软件开发和评价科学课教学模式.开发计算机软件我们为Windows开发了名为“波尔卡”的软件，这是一个可重复播放的绘图系统。该系统可以记录儿童绘画的全过程，并可以回放绘画过程。它支持儿童的反思性思维，帮助儿童构建科学概念。该软件可以从网站下载。2.科学课教学模式的发展我们邀请本研究计画的合作成员教师在他们的科学课中使用波尔卡，以发展一些使用波尔卡的教学模式。在几个教学单元中使用波尔卡进行了科学课;例如，压力空气、流水功、电流、光合作用、以及各种教育实践都在会议上作了报告.通过教学实践，说明了软件中动画功能的需求.因为在某些教学单元中，儿童往往把自己的想法表现为现象的变化过程。所以我们决定应用新的研究项目来开发新的软件。

In this research project we aimed to develop a computer software which support children to construct scientific idea and models, and to develop and to assess teaching models of science lesson using the software.1. Developing computer softwareWe developed the software for Windows named "Polka" that is a Repeat-Playable-Drawing System. The system can record all process of children's drawing and can replay the process of drawing. It support children's reflective thinking and ease children to construct scientific ideas. The software is able to download from the web site.2. Developing teaching models for science lessonWe asked cooperative member teacher of this research project to use Polka in their science lesson to develop some teaching models using Polka. Science lessons using Polka had conducted in several teaching unit ; e.g., pressed air, work of flowing water, electric current, photosynthesize, and each educational practice ware reported in conferences.3. Through educational practices the needs of function of animation in the software. Because in some teaching unit children usually present their idea as the changing process of the phenomenon. So we decided to apply the new research project to develop new software.
