Social Network Implications of Normative School Transitions in Non-Urban School Districts.

This article expands research on normative school transitions (NSTs) from elementary to middle school or middle to high school by examining the extent to which they disrupt structures of friendship networks. Social network analysis is used to quantify aspects of connectedness likely relevant to student experiences of social support. Data were drawn from 25 communities followed from sixth to ninth grades.

Later Start, Longer Sleep: Implications of Middle School Start Times.

Background: Although adolescents generally get less than the recommended 9 hours of sleep per night, research and effort to delay school start times have generally focused on high schools. This study assesses the relation between school start times and sleep in middle school students while accounting for potentially confounding demographic variables.

Methods: Seventh and eighth grade students attending 8 late starting schools (∼8:00 am, n = 630) and 3 early starting schools (∼7:23 am, n = 343) from a diverse suburban school district completed online surveys about their sleep behaviors.
