Effects of a packaged teacher-consultant-mediated intervention program (CLASS) for modifying acting-out behavior in the regular classroom were evaluated. The experimental groups significantly increased their proportion of appropriate behavior postintervention and required fewer remedial services and special class placement years later. Training…

The purpose of this study was to determine (1) whether sex operated as a diffuse status characteristic in mixed-sex groups of fourth- and fifth-grade children (n=168), and (2) whether an intervention based on expectation states theory would be successful in changing the status relationships within such groups. (PN)

One hundred forty fourth graders were asked to solve proportion problems about juice-mixing situations both before and after an intervention that used a manipulative model or other materials in three experiments. Results indicate different approaches appear to be necessary to facilitate children's proportional reasoning, depending on the reasoning…
