The capacity of the field to conduct power analyses for group randomized trials (GRTs) of educational interventions has improved over the past decade (Authors, 2009). However, a power analysis depends on estimates of design parameters. Hence it is critical to build the empirical base of design parameters for GRTs across a variety of outcomes and…

The project, "Oxford Improving Numeracy and Literacy Programme," was delivered by Oxford University Department of Education. This evaluation tested two different initiatives with Year 2 children: "Mathematics and Reasoning" and "Literacy and Morphemes." The "Mathematics and Reasoning" programme aimed to…

Due to their motivational nature, there has been growing interest in the potential of games to help teach academic content and skills. This report examines how different levels of detail about a game's scoring rules affect math learning and performance. Data were collected from 164 students in the fourth to sixth grades at five after-school…

Results after two years of using three reading comprehension curricula show gains from one program and no effects for the other two on reading comprehension for fifth-graders, according to a study released by the National Center for Education Evaluation and Regional Assistance in the Institute of Education Sciences. The study focused on whether…

The accuracy with which regression models estimate treatment effects is dependent upon a number of conditions. The stability of the regression line (a function of sample size and correlation between pretest and posttest) is said to be the most important of these conditions. The utility of regression models is proportional to the size of the…

The present study examined outcomes on the Tennessee Comprehensive Assessment Program/Achievement Test (TCAP/AT) for the KIPP:DIAMOND Academy (KIPP:DA), which is in its second year of operation. Importantly, as in Year 1, a rigorous quasi-experimental research design was employed, in which each KIPP:DA student was individually matched to a highly…
