Without further ado, here is a link to the Periscope for you to watch to get an idea of how their work was shared out globally.
You can also get an idea of the apps the students featured by looking through this Google Slide deck the teacher, Rachel Murat, shared.
Here are three screen captures from the slide deck:
Here is a sample of the Google Form (survey) that was filled out to evaluate each of the apps presented. Students later created a blog post to support their top choice.
Overall, I was fortunate to watch the live presentation via Periscope to see the class in action and was impressed by the way the students took control of the learning, sharing their favorite apps with others and defending their choices as well as explaining how the app worked and its benefits.
