Educators and policymakers have demonstrated interest in finding ways to better equip mathematics teachers so they can help students achieve at a higher level. Academic coaching has been identified as an effective professional development activity for teachers. The purpose of this study was to investigate the difference between students'…

An empirical study was conducted in order to obtain treatment effect estimates with the Special Regression model for groups in which there was no treatment. General mathematics test scores were obtained from 730 ninth graders in city schools somewhat similar to Title I schools, but in which no special treatments were given. Hypothetical…

The results of a study which used the regression discontinuity model in the analysis of criterion-referenced test data are presented and inherent drawbacks in the use of the regression discontinuity model with this type of data are discussed. The discussion is based on the results of an analysis of data collected in the Mesa, Arizona School…

Mathematics achievement of Elementary Secondary Education Act Title I students was evaluated, using RMC Model B, the control group model. The third-grade students in 8 of 17 Title I elementary schools and the fifth-grade students in the remaining 9 schools were chosen for the pilot project. The remaining third-and fifth-grade students served as…

Title I evaluations using the RMC Model C design depend for their interpretation on the assumption that the regression of posttest on pretest is linear across the cut score level when there is no treatment; but there are many instances where nonlinearities may occur. If one applies the analysis of covariance, or model C analysis, large errors may…
