Good page of reference resources created by a district implementing a 1:1 Chromebook program in high school.
"it’s time that we look at apps to find those that help us gain a better look into student thinking and understanding. I have created a list of my favorite apps that purposefully achieve this goal. There are of course more apps than these that create informative artifacts of learning, but I like to keep the list simple and concise so that teachers and students only have to learn a few apps -and can focus on content not on learning new platforms.
The following list will help make student thinking visible not only to the teacher – but hopefully to the world.
Each app is linked – have fun exploring them."
