There is a new tool around that I only learnt about recently but looks to make a huge difference in the EdTech scene. It is Oppia, a site that allows you to use and create interactive learning activities online. While there are similar tools like iTunes U that are fantastic, Oppia adds extra features that make them very useful to teachers. Oppia is responsive to students answers, allowing them to work within their ZPD, not move on to harder topics before they are ready. It is free, with no trial period or extra paid features, making it perfect for the classroom. Everything is also licenced using creative commons, so you can copy, use or modify parts of courses to your heart’s content. Oppia is still in beta, so there may be bugs and there is not a lot of content available yet, but because it is open source, anyone can make suggestions or even improve the code themselves! I have no doubt that we will be seeing a lot more of Oppia in the future.
