一个原型的多媒体程序，多媒体和心理模型在化学（4M：CHEM），开发，以促进学生在课堂上学习。4M：CHEM利用计算机分屏设计来显示真实的实验的同步视频、这些实验的分子级动画、宏观性质或结构图的真实的时间图以及化学方程式。这四个窗口可以单独显示或以任何组合显示。当多个窗口被激活时，每个窗口中的操作都是同步的。这些化学现象的同步观点可以暂停和重新开始，以帮助讨论宏观，微观和符号表征之间的联系和局限性。原型程序涉及32个实验处理物理，气体，溶液和非均相平衡。包括定性和定量实验，以帮助学生建立化学的理解和直觉，以及提高他们的定量问题，使他们能够更好地理解化学。
A prototype multimedia program, Multimedia and Mental Models in Chemistry (4M:CHEM), was developed to facilitate student learning in the classroom. 4M:CHEM utilizes a computer split-screen design to show simultaneous videos of real experiments, molecular-level animations of these experiments, real time graphs of macroscopic properties or structural diagrams, and chemical equations. These four windows can be shown individually or in any combination. When multiple windows are activated, actions in each are synchronized. These synchronized views of chemical phenomena may be paused and restarted in order to aid discussions of connections between and limitations of macroscopic, microscopic, and symbolic representations. The prototype program involves 32 experiments dealing with physical, gaseous, solution, and heterogeneous equilibria. Both qualitative and quantitative experiments are included to assist students in building chemical understanding and intuition as well as enhancing their quantitative problem so...
