North Carolina A&T Physlet^® Library

Library Index

For a current version of the library, please visit http://ed.phys.ncat.edu/ccliepl/.

The NC A&T Physlet^® Library is an on-line repository of Physlet animations. The library was initially developed as part of an NSF CCLI EMD grant to develop and study multimedia-focused kinematics questions that use Physlets. At present, it contains only the animations recently developed for the grant; however, in the future, it is hoped that the library will host animations developed by many authors.

The goal of the library is to make it easy to share Physlet animations and modify Physlet animations for your own use. Making a useful library presents many challenges, especially pertaining to the classification of animations. Your suggestions for improving the library are welcomed and appreciated. Presently I have organized my animations by features, such as the representation of physical quantities via data, graphs, or vectors and whether the animation includes interactivity such as manipulation of vectors or initial conditions. This is so that you can easily find animations with the features you desire. Also, it helps you find examples for how to incorporate certain features into your own animations.

By viewing the source, you can easily copy the JavaScript and make modifications. Otherwise, you can use the animations just as they are and add your own questions, tutorials, or activities.

The home page for this CCLI project is at http://ed.phys.ncat.edu/ccliepl/developers/. Let me know if you are willing to participate in a study of the effectiveness of the Physlet-based questions for instruction or assessment.

If you use animations from the library, I would appreciate an email from you so that I can report it to NSF who is funding this project. Thank you.
