Standardized total effects of predictor variables on TDS at the classroom level ranged from −0.02 to 0.25. Predictor variables that had the strongest standardized total effect on TDS included positive technology beliefs (β = 0.25), pressure (β = 0.20), technology experience (β = 0.20), and integration obstacles (β = −0.20). Note that integration obstacles’ effect was negative, whereas other variables had positive effects. Results suggest that, at the classroom level, predictor variables may have small to moderate effects on TDS. Integration obstacles appear to have moderate negative effects on TDS and on two important predictors of TDS, technology experience and positive technology beliefs. Results suggest that teacher factors such as beliefs about IT’s benefits and experience with technology may increase the extent to which teachers direct their students to use technology, and that teachers whose principals emphasize IT use may increase the extent to which they direct students to use technology. Conversely, teachers who experience obstacles with IT integration may be less likely to direct their students to use technology than teachers who do not experience such obstacles.
