A
Separate regression models were conducted for each individual variable adjusting for grade level and site location in each model
B
Dummy variables for class location : indoor classes= 1 and outdoor classes =2; classes in both location were excluded from this sample
C
Dummy variables for teacher gender: male teachers= 1 and female teachers =2
D
Sedentary Lesson Context refers to the combination of % time in management and knowledge contexts
E
Active lesson context refers to the combination of % time in games, fitness, and skills
