Interactive Multimedia and the Mental Model of Equilibrium in Chemistry

人们对科学的危机有着广泛的共识 教育 学生太少，特别是少数民族， 女性毕业时获得了理科学位。 此外，委员会认为， 选修科学课程的学生经常会发现， 不参与，他们无法理解的概念和基础 代表科学现象的原理。这个项目 建议开发一个原型，交互式多媒体系统 大学化学入门课程，使用最先进的 技术. 有了这个原型，我们将开发一个初始的 化学平衡单元，允许用户 在化学系统上操作并观察结果， 综合、多重、同时的表现形式，包括： 化学符号，反应视频，分子水平 动画、动态图形、显示吸收光谱、pH值 图表和表格数据。软件和辅助材料 将使大型讲座更具互动性， 参与，并帮助学生发展多个，综合， 化学现象的心理模型。 我们会研究 系统对学生理解和兴趣的影响 在科学上。 随后的一项全面提案将扩大 整个化学导论课程的环境。

There is widespread consensus on the crises in science education. Too few students, particularly minorities and women, are graduating with science degrees. Furthermore, students who take science courses frequently find them unengaging and they fail to understand concepts and underlying principles that represent scientific phenomena. This project proposes to develop a prototype, interactive multimedia system for introductory college chemistry using state of the art technology. With this prototype, we will develop an initial unit on chemical equilibrium that will allow the user to operate on chemical systems and observe the results in integrated, multiple, simultaneous representations, including: chemical symbols, video of the reaction, molecular-level animations, dynamic graphs, displays of absorption spectra, pH graphs, and tabular data. The software and supporting materials will be designed to make the large lecture more interactive and engaging and to help students develop multiple, integrated, mental models of chemical phenomena. We will examine the impact of the system on student understanding of and interest in science. A subsequent comprehensive proposal will extend this environment to the entire introductory chemistry course.
