Abstract: This is a technical report detailing the analytic methods used to assess the effects of a virtual professional learning community (vPLC)-enhanced ASSISTments intervention. The report uses a quasi-experimental design and partially nested regression model to account for clustering and reveals that while overall effects were positive but not statistically significant, rural students and those with lower levels of performance experienced meaningful gains in math achievement.
