Congratulations! You've made it through the first half of the course. Here's your badge, enjoy it with pride. Okay, well hopefully if you've been listening to my lectures over the past three weeks, you understand that just throwing a badge up there doesn't necessarily make this course any more fun and motivating. Some of you may feel like there's nothing that could make the class fun and motivating, but if you've gotten this far, hopefully you found some value in what I've talked about. The first half of the course, up till now, is about frameworks and concepts. So we've talked about what gamification is, we've talked about what games are, we've talked about game thinking, which is basically the intersection of the two, and we've talked in some detail about psychology and motivation. Those are the fundamental building blocks to good gamification. The second half of the course is about application. We'll look at how to take these concepts and put them into practice in different ways. The next week will be about design. The framework and processes for implementing gamification, step by step. The week after that will be about application in specific domains, in particular, gamification in the enterprise, i.e within organizations, for employees and so forth, and gamification for social good and behavior change. And then in the final week, we'll focus in on some of the risks and dangers involved in gamification, and then look towards the future at interesting new ways that gamification is evolving, beyond the core kinds of examples that we're talking about in the course. So, we've come a long way, let's move on next week and apply the concepts that we've learned so far.
