Like Khan Academy, you should add in a points system to identify top viewers/users
Add gamification to this website! Really, it's like the icing on the cake. Give points for completing a video and/or answering practice questions correctly. I'm not sure how you would code this ... but think about it!
See Khan Academy for an example of this.
Great idea Zach. We’re all about incentives here right! This is on our list to do – let me know if you have any ideas on specifics you’d like to see.
Duolingo is an excellent example of gamified language learning. Available on the web, android, and ios. I use all three. It awards 10 pts for each submodule completed and 2 lingots (language + ingot) which you can use to buy special modules. A question within a submodule could be: listen and transcribe, listen and translate, fill in the blank, translate text, arrange grammatical elements like a puzzle and, in some languages, speak into a microphone. You can "follow" other learners and post your progress on Linked in. It feels like a game, is fun, and is addicting.
