This article considers the status of research on PD and articulates a particular direction for future work. Little is known about whether PD can have a positive impact on achievement when a program is delivered across a range of typical settings and when its delivery depends on multiple trainers. Despite a consensus in the literature on the features of effective PD, there is limited evidence on the specific features that make a difference for achievement. This article explains the benefits offered by experiments in addressing current research needs and?for those conducting and interpreting such studies?discusses the unique methodological issues encountered when experimental methods are applied to the study of PD.}, number = {8}, urldate = {2020-05-15}, journal = {Educational Researcher}, author = {Wayne, Andrew J. and Yoon, Kwang Suk and Zhu, Pei and Cronen, Stephanie and Garet, Michael S.}, month = nov, year = {2008}, note = {Publisher: American Educational Research Association shortDOI: 10/fhz33n KerkoCite.ItemAlsoKnownAs: 10.3102/0013189X08327154 10/fhz33n 2405685:FDVV5CN4}, keywords = {C:United States / International}, pages = {469--479}, }
