註釋This is the second and final report of the Middle School Mathematics Professional Development Impact Study, which examines the impact of providing a professional development (PD) program in rational number topics to seventh-grade mathematics teachers. An interim report (Garet et al. 2010) described the findings after one year of PD. The current report documents the impact after providing a second year of PD in a subset of the original participating districts and includes supplemental analyses that use data from both years of the study. The study produced the following core second-year results: (1) The study's PD program was implemented as intended, but teacher turnover limited the average dosage received; (2) At the end of the second year of implementation, the PD program did not have a statistically significant impact on teacher knowledge; and (3) At the end of the second year of implementation, the PD program did not have a statistically significant impact on average student achievement in rational numbers. (Contains 4 tables, 2 figures and 14 footnotes.) [For "Middle School Mathematics Professional Development Impact Study: Findings after the Second Year of Implementation.
