An investigation was conducted to determine how fifth graders with pri
or experience in student-led literature discussions acted as ''knowled
geable others'' for peers whose prior discussion experiences had been
teacher led and grounded in a basal reading program, All of the studen
ts were participating in Book Club, a literature-based reading program
designed to support student-led discussions. Analysis, conducted indu
ctively with categories emerging from the data, revealed that even wit
hin the 1st month of working together, students adopted leadership rol
es, participated in discussions exhibiting various interactional patte
rns, and helped one another conduct their discussions. On the basis of
the inquiry, it appears that students can facilitate one another's le
arning, but the teacher has an important role in monitoring student di
scourse and planning instruction that meets emerging needs.
