This article explores the meaning of curricular differentiation for id
entified gifted students by examining learner responses to open-ended
activities. Very little research supports or describes how open-ended
activities-which have been advocated as a strategy to allow students t
o work in their own interest areas, in their own learning styles, and
at their own ability level-serve to differentiate the curriculum. This
paper sets curriculum differentiation in a historical perspective, re
views a comprehensive investigation into the nature of open-ended acti
vities, and focuses on how and in what ways the responses to open-ende
d activities of children identified as a gifted differed from response
s of children who were not identified as gifted in a third-grade a fou
rth-grade heterogeneously grouped classroom. The study also focuses on
teacher perceptions of classroom activities and learner responses. Da
ta sources included observations over the course of one academic year,
interviews with teachers and students, learning style and interest as
sessment instruments, and documents related to over 33 open-ended acti
vities. Based on the findings reported here, the author proposes a ree
xamination of the meaning of curricular differentiation with a renewed
emphasis on determining how an instructional strategy, for example, p
roviding open-ended activities, maximizes student's capabilities.
