Exploring Future Research in Physical Education: Espousing a Social Justice Perspective.

Although there has been forward movement in identifying and addressing diverse learning needs, social justice education is not a significant part of the current standards for beginning teachers or K-12 students in the U.S. Throughout our standards-based history, social justice has been more of a hidden curriculum.

Pedometer steps-per-minute, moderate intensity, and individual differences in 12- to 14-year-old youth.

Background: Researchers have noted both the utility and limitations of using pedometers to measure physical activity (PA). While these unobtrusive devices are widely accepted for their ability to measure accumulated PA, they have been criticized for their inability to measure exercise intensity. However, recent steps-per-minute (SPM) research provides reasonably accurate measures of intensity allowing users to assess time spent at recommended PA levels.
