Observations of the middle school environment: The context for student behavior beyond the classroom

This article describes the use of an observation system to measure middle school staff practices, environment characteristics, and student behavior in the school common areas. Data were collected at baseline from 18 middle schools participating in a randomized controlled trial of school‐wide Positive Behavior Support. The observations were reliable and showed sensitivity to differences between school settings and between schools. Multilevel models with students nested in schools were used to examine the associations of staff practices and the school environment with student behavior. Less effective behavior management and more staff criticism, graffiti, and percentage of low‐income students were associated with student problem behaviors. Greater use of effective behavior management and positive attention, and fewer low‐income students were associated with positive student behavior. The use of data‐based feedback to schools for intervention planning and monitoring is illustrated. Implications for school‐wide efforts to improve student behavior in middle schools are discussed. © 2011 Wiley Periodicals, Inc.     

Infants Learn Baby Signs From Video

There is little evidence that infants learn from infant‐oriented educational videos and television programming. This 4‐week longitudinal experiment investigated 15‐month‐olds' (N = 92) ability to learn American Sign Language signs (e.g., patting head for hat) from at‐home viewing of instructional video, either with or without parent support, compared to traditional parent instruction and a no‐exposure control condition. Forced‐choice, elicited production, and parent report measures indicate learning across all three exposure conditions, with a trend toward more robust learning in the parent support conditions, regardless of medium. There were no differences between experimental and control conditions in the acquisition of corresponding verbal labels. This constitutes the first experimental evidence of infants' ability to learn expressive communication from commercially available educational videos.
