My name is James Baker and I am a graduate student in the Department of Communication Studies at West Virginia University. I am conducting a meta-analysis on the effects of PowerPoint/Prezi on learning. If you have an unpublished paper, dissertation, thesis, or conference paper in this area, please email me at jpb0020@mix.wvu.edu to be included in the meta-analysis. Also, if you have already received this message, my apologies, I am exhausting as many avenues as possible to retrieve unpublished manuscripts. Thank you for your time.
