The purpose of this article is to extend our understanding of groupwork in
the science classroom-to use the sociological construct of status (defined
here as a student's perceived academic ability and popularity) to explain i
nequitable participation by group members and to identify strategies that p
romote reasoned consideration of all ideas within groups. Toward these ends
, I investigated three classes of one sixth-grade science teacher at an urb
an, ethnically diverse middle school. Students in these life science classe
s used an instructional strategy and curriculum designed explicitly to addr
ess differences in their access to and understanding of science: the Comple
x Instruction model of groupwork and the Human Biology Middle Grades Life S
cience Curriculum. Over the course of two units, I examined the powerful in
fluence of status on student-student interactions during groupwork and stud
ent performance on science tests. I used quantitative observation instrumen
ts and semistructured student interviews to ascertain the quality of groupw
ork implementation, audio- and videotapes of target groups to study the rel
ationship between status and participation, and a Rate of Talk Instrument a
nd unit tests to determine if students' participation during groupwork infl
uenced their achievement in science. Because status issues were not fully a
ddressed by teacher and curriculum, inequities in both groupwork participat
ion and science learning persisted. Three recommendations for groupwork ref
inement are offered: the consistent implementation of interventions designe
d to amelio-rate status differences; the strategic assignment of procedural
roles to ensure student access to group materials, discourse, and decision
s; and the overturning of students' conventional notions of intelligence-wh
at they think it means to be smart. (C) 1999 John Wiley & Sons, Inc.
