The development of technologies such as probeware requires training, not only in its use, but also in its integration into the curriculum. It is a common practice for schools to spend large portions of their budget on purchasing technology while neglecting to provide funding for the much-needed professional development. The availability of online professional development has provided in-service teachers opportunities to overcome traditional barriers of distance and time and allowed them to seek out and participate in much needed training. In recent years online instruction has incorporated the use of Web 2.0 tools to facilitate professional development for science teachers. While research on the use of Web 2.0 tools in professional development have been conducted, research on newer tools, such as VoiceThread, that can be used to deliver instruction is limited. In light of the increased use (purchase) of probeware in our schools the question of whether or not professional development can be effectively delivered through the use of VoiceThread has been the focus of this research.
