Alibali, Martha W.; Kao, Yvonne S.; Brown, Alayna N.; Nathan, Mitchell J.; Stephens, Ana C. – Wisconsin Center for Education Research (NJ1), 2009
This study investigated middle school students' conceptual understanding of algebraic equations. Participants in the study--257 sixth- and seventh-grade students--were asked to solve one set of algebraic equations and to generate story problems corresponding with another set of equations. Structural aspects of the equations, including the number…

Nathan, Mitchell J.; Eilam, Billie; Kim, Suyeon – Wisconsin Center for Education Research (NJ1), 2006
Theories of learning in social settings, no matter their philosophical orientation, must address issues of intersubjectivity (IS). This paper starts with the premise that IS is a fundamental and unavoidable aspect of social interaction, and that understanding its nature is necessary for developing reliable theories of socially mediated learning…

Visual Display and Co-Expressivity as Students Strive for Intersubjectivity in a Spatial Reasoning Task. WCER Working Paper No. 2005-10
PDF on ERIC Download full text
Nathan, Mitchell J.; Eilam, Billie – Wisconsin Center for Education Research (NJ1), 2005
This paper explores the role of co-expressivity of drawing, speech, and gesture as sixth graders strive for intersubjectivity in their attempts to communicate solutions of a spatial reasoning task. Several obstacles to intersubjectivity are documented, particularly conflicts between a literal and geometric interpretation, limits of students'…
