This collaborative, naturalistic study examined the functions outlinin
g served for 122 students in four undergraduate classes, each in a dif
ferent discipline. Nearly two-thirds (65%) of the students outlined at
some time, and they variously intermingled outlining with other strat
egies across a wide spectrum of the composing process. However, outlin
ing functions varied widely according to the assignment and the teache
r's guidance. The study identified 5 functions: 1) students' use of ge
neric formats to guide their work on a paper; 2) students' use of outl
ining as a bridge between content and structure; 3) students' use of o
utlining to impose order on their own ideas; 4) students' use of outli
ning to generate, preview, and evaluate modes of arrangement of their
writing; and 5) students' use of outlining to summarize progress and t
o motivate their writing projects. However, some students used the gen
eric outline too broadly to dictate the sequences of idea-generation,
information-gathering, and composing, while some used it too narrowly,
merely as a sequence of boxes, ignoring the interrelations among part
s that their teachers expected. The study suggests the benefits of exa
mining a specific strategy instantiated in a particular written form,
such as the outline, rather than concentrating only on ''processes,''
as much previous writing research has done.
