Deployment Study Length: How Long Should a System Be Evaluated in the Wild?
Khai Truong, Julie Kientz, Nilanjan Banerjee, A. J. Brush, Ratul Mahajan
There are many different ways to evaluate a novel interactive system. However, placing that system into the hands of real users and allowing them to use it as they would like in their natural environments may arguably be the best approach to understand if it "really" works. This is because findings learned from user studies conducted in the lab or a controlled setting are limited in external validity and therefore might not generalize beyond the studied usage scenario. Furthermore, the scenario used in a controlled study often lacks full authenticity, and thus it may not faithfully represent situations from the users' live.

Democratizing Computing with App Inventor
David Wolber, Harold Abelson, Mark Friedman
MIT App Inventor is a visual blocks language that enables beginners and non-programmers to create apps for their phones and tablets. It has empowered thousands to create software with real-world usefulness, and see themselves as creators rather than only consumers in the mobile computing environment. Educationally, it offers a “gateway drug” that can help broaden and diversify participation in computing education.
