Jeremy Hiebert takes us on a welcome trip back to the writings of David Squires. In this item, Squires states the constructivist dilemma quite nicely: "In trying to design effective learning environments we may at the same time constrain the levels of freedom necessary for learners to make decisions about their own learning." His solution, "incorporated subversion," is to build the freedom into the tools. "Rather than design with constraint in mind, design with freedom and flexibility in mind." Hiebert also links us to a Squires interview from 2000 where he describes the Peripatetic Electronic Teachers who are "freelance teachers who use the features of new technologies to create and deliver learning experiences."
