The technology was transitioned to Carnegie Learning, which made it the center piece of the mathematics courses they have developed and market. Their web site has reports from many successful evaluations. The Algebra and Geometry LearnLab courses are the result of a partnership between PSLC, Carnegie Learning and several school districts.
