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

在本研究项目中，我们的目的是开发一个计算机软件，支持儿童构建科学的观念和模型，并利用该软件开发和评估科学课的教学模式。开发计算机软件我们开发了Windows环境下的软件“Polka”，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，方便儿童构建科学的思想。该软件可以从网站下载。开发科学课的教学模式我们邀请了本研究项目的合作成员教师在他们的科学课中使用Polka来开发一些使用Polka的教学模式。在几个教学单元使用Polka进行了科学课程；例如，加压空气、流水做功、电流、光合作用，并在会议上报告了每一次教育实践。通过教育实践，分析了软件中动画功能的需求。因为在一些教学单元中，孩子们通常会把他们的想法呈现为现象的变化过程。因此，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.
