Explore Learning, originally a dissertation project, allows students to visualize and alter parameters in topics such as mechanics and life sciences.
Specific labs include mouse genetics, golf range motion, orbit simulators, etc. Such labs will allow manipulations that are far more complex to implement in the real world.
ExploreLearning has borrowed sound learning features from the video game world, such as collaboration and multiplayer, to guide their “gizmos” or math and science simulations. The content collection for K-14 is so comprehensive that other curricula would supplement rather than supplant these modeling tools. The graphics are pleasing without being overly complex. It is a subscription service but the fees, in contrast to other online collections, are very reasonable.
