This research study examined whether and how professional development can help teachers design sequences of instruction that lead to improved science learning. The efficacy of three professional development programs and a control condition was compared in a cluster randomized trial involving 53 middle school science teachers from a single school…

As online professional development courses for teachers have grown, the discussion forum has become a locus of considerable research. This study analyzes the discussion forums in four different sessions of a short (4-week) online course for teachers from six schools in three states.
