Before steps are taken to impose limits on the use of social media and mobile technologies in schools, policymakers and educators need to consider the consequences for learning that such restrictions would produce. In this document, we argue that such action should carefully consider the advantages of social media for learning and that these guidelines for responsible use bring media into mentored environments where they can be safely explored and shared.
Many of the problems raised by these new technologies – from bullying to engaging in risky behavior – are not new to the public discourse, but are merely being delivered in different media. The challenge to responsible educators remains the same: to provide stimulating and safe learning environments that support the acquisition of practical skills necessary for full participation as a 21st-century citizen. Achieving this without mentored use of new technologies seems both impractical and counterproductive. One of the most powerful reasons to permit the use of social media and mobile devices in the classroom is to provide an opportunity for students to learn about their use in a supervised environment that emphasizes the development of attitudes and skills that will help keep them safe outside of school.

The Cabinet Office’s Centre for Social Impact Bonds has developed two new tools to assist the development of the bonds: the 'Knowledge Box' online portal and a template service agreement contract.
large groups of people are smarter than an elite few, no matter how brilliant—better at solving problems, fostering innovation, coming to wise decisions, even predicting the future
Graph mining refers to extracting knowledge from massive graphs. The data sets of telephone calls we see at AT&T can be viewed as a single graph, with several hundred million phone numbers as nodes, and calls between phone numbers as edges. It is a giant social network, like an internet connections graph or a rich citation network.
My advisor is Prof. Ben Shneiderman, and I am a member of HCIL. My research is in the Information Visualization area of the Human-Computer Interaction field. My current research involves Network Visualization. I developed a tool called NVSS (see NVSS project page) to visualize netwoks (citation networks, food webs, social networks, etc.) using semantic substrates.

Soziale Netzwerke wie Twitter oder Facebook, die auf einem ständigen Kommunikationsfluss basieren, können die moralischen Einstellungen ihrer Nutzer abstumpfen. Das behaupten Forscher der Universität von Süd-Kalifornien, die in den Plattformen eine Überforderung für das menschliche Gehirn orten. Besonders junge Menschen seien aufgrund eines überdurchschnittlich hohen Ausmaßes an Kommunikation gefährdet und drohen bei ständiger Nutzung auf Dauer Schaden zu nehmen. Das ständige Erhalten neuer Nachrichten und die mögliche Vielzahl an sozialen Kontakten würden zu einer "Überkommunikation" führen. Der "moralische Kompass" im Gehirn sei von den Online-Angeboten überfordert.
Problem: Malcolm, Zoe, Kaylee, Simon, and River all work together on the same web development team. They are avid Twitter users and want a similar way to broadcast quick messages and updates to everyone on their team. Since these messages may contain confidential information, the team doesn't want them published to their public Twitter timelines or to any followers who are not part of the team. Solution: GroupTweet allows Malcolm and the gang to send messages via Twitter that are instantly broadcasted privately to only the team members.
