Social constructivist perspectives focus on the interdependence of soc
ial and individual processes in the co-construction of knowledge. Afte
r the impetus for understanding the influence of social and cultural f
actors on cognition is reviewed, mechanisms hypothesized to account fo
r seaming from this perspective are identified, drawing from Piagetian
and Vygotskian accounts. The empirical research reviewed illustrates
(a) the application of institutional analyses to investigate schooling
as a cultural process, (b) the application of interpersonal analyses
to examine how interactions promote cognition and learning, and (c) di
scursive analyses examining and manipulating the patterns and opportun
ities in instructional conversation. The review concludes with a discu
ssion of the application of this perspective to selected contemporary
issues, including: acquiring expertise across domains, assessment, edu
cational equity, and educational reform.
