The ChemCollective: On-line virtual laboratory |
| The ChemCollective (http://www.chemcollective.edu) is a collection of virtual labs and online activities for introductory chemistry. Our virtual lab, a flexible Java applet, allows students to choose from hundreds of standard reagents and manipulate them in a manner that resembles that of a real lab. The lab couples the paper-and-pencil activities of the current course with activities that involve chemical manipulations and experimental design. By allowing students to see the species and concentrations present in their solution, the lab bridges laboratory manipulations with the numbers that are the focus of their algebraic calculations. These materials have been tested mostly in a classroom setting, but we have recently incorporated them in to an online course in stoichiometry and the tools are well suited for general distance learning. |
