Discussed are how a free choice environment can be established in the classroom, the motivational advantages to including free choice in an enrichment program, and how implementing a free choice environment can serve as a teacher training tool. Several free choice studies are described. In one such study, a free choice situation was set up in three regular fifth-grade classrooms as an aid to instruction. In two classes free choice was combined with direct instruction in scientific reasoning; in the third class, free choice alone was presented. It was found that free choice combined with instruction was more effective than free choice alone in teaching scientific reasoning. (MH)
