Complex research questions often need large samples to obtain accurate estimates of parameters and adequate power. Combining extant data sets into a large, pooled data set is one way this can be accomplished without expending resources. Measurement invariance (MI) modeling is an established approach to ensure participant scores are on the same…

Many of the analytical models commonly used in educational research often aim to maximize explained variance and identify variable importance within models. These models are useful for understanding general ideas and trends, but give limited insight into the individuals within said models. Data envelopment analysis (DEA), is a method rooted in…

Selecting assessments for adults who struggle with reading can be difficult because few literacy measures used by reading researchers have been normed on this population, leaving uncertainty regarding the validity of these tests for adult learners. This study focused on the performance of 116 adults reading between the 3rd and 8th grade levels on…

This paper presents evidence on the amount of classroom variation in gains across various domains of achievement within the Tennessee Voluntary Pre-Kindergarten (TN-VPK) program; the data are taken from the randomized control trial (RCT) design of the TN-VPK evaluation. This study explores areas where those differences are largest, and offers…

As policymakers contemplate expanding preschool opportunities for low-income children, one possibility is to fund 2, rather than 1 year of Head Start for children at ages 3 and 4. Another option is to offer 1 year of Head Start followed by 1 year of pre-K. We ask which of these options is more effective. We use data from the Oklahoma pre-K study…

This randomized control trial study evaluated the effectiveness of the solution-focused approach in addressing academic, motivational, and socioemotional needs of 14 children with reading difficulties. The intervention group received five 40-min solution-focused sessions. The control group received academic homework support. Results showed…

In the present study, we present analyzed profiles of observed classroom experiences in terms of emotional and instructional dimensions of quality. Over 800 first-grade classrooms across the United States were included, selected by virtue of having a student participating in the National Institute of Child Health and Human Development's Study of…

To date, reports of reading interventions for students at risk for emotional/behavioral disorders (E/BD) that have been published in refereed journals have involved sustained support by university or school-site personnel. This study examined the efficacy and feasibility of a reading intervention that 2 general education teachers implemented in…

The purpose of this study was to investigate the effects of a peer-delivered "Corrective Mathematics" program ("CM"; Engelmann & Carnine, 1982) in a secondary general education classroom with students with low mathematics performance. Ten learners and 9 peer tutors participated in the study. Peer tutors instructed…
