Relying on a series of four experiments, F. J. Boster, G. S. Meyer, A. J. Roberto, C. Inge, and R. E. Strom (2006) demonstrated that students exposed to videostreaming exhibited more improvement in examination performance than control students. In extension, this study tests the effect of using videostreaming with a very different topic (mathematics), with a very different student population (large urban), and with different grades (sixth and eighth). The results replicated Boster et al. (2006) and indicate that the mean examination performance for those in the video-streaming condition exceeds the mean examination performance of the control group. (Contains 2 tables.)
