Studying new forms of participation

Stephen J. Hegedus and William R. Penuel wrote an article that was recently published online in Educational Studies in Mathematics. The article is called "Studying new forms of participation and identity in mathematics classrooms with integrated communication and representational infrastructures", and here is the abstract of the article:

Wireless networks are fast becoming ubiquitous in all aspects of
society and the world economy. We describe a method for studying the
impacts of combining such technology with dynamic,
representationally-rich mathematics software, particularly on
participation, expression and projection of identity from a local to a
public, shared workspace. We describe the types of mathematical
activities that can utilize such unique combinations of technologies.
We outline specific discourse analytic methods for measuring
participation and methodologies for incorporating measures of identity
and participation into impact studies.
