How can we deliver on the promise of technologies for education and help learning become more social and engaging for students? The Internet and other technologies have transformed nearly every aspect of our society, particularly in the scientific and commercial sectors, yet classrooms of today appear largely as they did more than 50 years ago (Tyack and Cuban, 1999; DiSessa, 2000). This contrasts with students’ experience outside of the classroom, as evidenced by the explosion of the social web (Web 2.0), where interactions and learning have increasingly become collective products rather than individual efforts.
