administered in 2005-2006 and Mobility Survey administered in 2006-2007 to all study teachers. |
Note: Classroom practice means are weighted and regression-adjusted using ordinary least squares to account for differences in baseline characteristics and the study design. Student achievement
means are regression-adjusted using a least squares model to account for baseline
characteristics and clustering of students within schools. The test scores are expressed as zscores,
with mean of 0 and standard deviation of 1 within each district and grade. |
*Significantly different from zero at the 0.05 level, two-tailed test. |
