Described by the teacher is the removal of a 10-year-old hyperactive boy from drug therapy (Ritalin). The setting, open classroom, and the involvement of four regular classroom teachers and a progressive teacher employing behavior modification in a small group setting are thought to be related to the boy's academic and behavioral progress. The boy is reported to have maintained control in this situation after 7 months without drug therapy and in a followup at the middle (junior high) level. (Author/DB)
