An extensive search of the literature on clinical supervision yielded 29 research studies and 3 works in progress. Studies using comparative measures conducted in K-12 school settings with inservice not preservice personnel were selected. These were grouped into four areas: attitudes toward supervision, effects of training, characteristics of…

Current research indicates that hospitalized children may profit best from preparation for surgery that is individually suited to their particular way of responding to hospitalization.

Replicated a study of boys with conduct problems using a parent-mediated treatment. Parents were trained to alter deviant behavior by following procedures derived from social learning theory. Child behavior showed significant change through termination as measured by parental reports. Follow-up data showed improvements were maintained through one…

Over 150 papers and articles were examined, and interviews with noted computer-based instruction (CBI) professionals were conducted to obtain information about CBI and the research evidence. Focus was on four main areas of CBI research--costs, learning achievements, individual differences, and student attitudes. Consistent empirical evidence did…

This report describes the construction and use of a conceptual framework and procedures for a program-fair, comparative, classroom-focused assessment of 4 kindergarten reading readiness (KRR) programs in kindergarten classes of 115 school districts.
