Classcraft
A very slick looking LMS system that uses gamification to promote student engagement. There are many nice features to this product, but the basic system does not make it easy for teachers to package their own lessons into the product. This is a major hurdle for many educators. The tools within the product to design content are insufficient for large scale use and are difficult to use.

The vast range of uses for this product are surprising many people. Language learning, however, has been one of the few areas of little growth. The game has tremendous excitement from students of all ages, but the entire game must be played within the game itself. This makes it difficult to control and also means students spend long periods with screen time, which is concerning for parents and teachers alike.
