Hi, GBL team, thanks for offering us an informative OER. I like the way you guys present these engaging contents. As an EVA, I have to say that personally I am not optimistic about the prospects of the educational game industry. The core strength of a good game is its ability to provide or facilitate players with something they can’t experience in their daily lives. For instance, players can create a virtual world in Minecraft, and create a variety of small programs or games with Scratch. The key to the success of these two applications is learning by doing, which enables players to experience project-based learning. While both Prodigy and Legends of learning are actually variant forms of an online quiz. The gaming elements are not the game itself. I highly doubt this kinds of educational games can help students improve their learning outcomes.
