The development of immersive virtual reality (IVR) hardware and software has accelerated in recent years. The conceptual vocabulary has, however, not received the same amount of attention, especially in the context of collaborative learning settings. Existing concepts such as immersion, presence and interactivity focus predominantly on the…

In vision-based augmented-reality (AR) environments, users view the physical world through a video feed or device that "augments" the display with a graphical or informational overlay. Our goal in this manuscript is to ask "how" and "why" these new technologies create opportunities for learning. We suggest that AR is…

The Learning Physics through Play Project (LPP) engaged 6-8-year old students (n = 43) in a series of scientific investigations of Newtonian force and motion including a series of augmented reality activities. We outline the two design principles behind the LPP curriculum: 1) the use of socio-dramatic, embodied play in the form of participatory…

Conversational technologies such as email, chat rooms, and blogs have made the transition from novel communication technologies to powerful tools for learning. Currently virtual worlds are undergoing the same transition. We argue that the next wave of innovation is at the level of the computer interface, and that mixed-reality environments offer…

In this paper, I review both mathematics education and CSCL literature and discuss how we can better take advantage of CSCL tools for developing mathematical proof skills. I introduce a model of proof in school mathematics that incorporates both empirical and deductive ways of knowing. I argue that two major forces have given rise to this…
