Abstract: | Twenty-six junior high and middle school science classes taught by 13 teachers were observed frequently during the first 2 months of school and during 2 months in the middle of the year to identify classroom management and instructional organization variables related to high levels of student task engagement and low levels of off task and disruptive behavior. Sub-samples of more and less effective managers were identified, and narrative data from their classes were analyzed to describe and illustrate effective strategies for managing science classroom activities. |
