This morning I used part of my snow day to create a video tutorial on how to create your first Android application through the MIT App Inventor. Watch the video then try making your first app. Or watch the video in one tab while following my instructions with App Inventor open in another tab.
Applications for Education
My 9th grade students are currently using it to create quiz game apps. One of them is trying to create a "personality quiz" application (what kind of cat are you?). I've personally used the App Inventor in the past to create a study guide for a U.S. History course that I taught. And I've seen 6th and 7th grade students use App Inventor to create scavenger hunt games.
