Sources of longitudinal achievement data are increasing thanks partially to the expansion of available interim assessments. These tests are often used to monitor the progress of students, classrooms, and schools within and across school years. Yet, few statistical models equipped to approximate the distinctly seasonal patterns in the data exist,…

School Improvement Grants (SIGs) exemplify a capacity-building investment to spur sustainable changes in America's persistently lowest-performing schools and stimulate the economy. This study examines both short- and longer-term effects of the first two cohorts of SIG schools from four locations across the country. Dynamic…

We compared students' performance on a paper-based test (PBT) and three computer-based tests (CBTs). The three computer-based tests used different test navigation and answer selection features, allowing us to examine how these features affect student performance. The study sample consisted of 9,698 fourth through twelfth grade students from across…

Idaho uses the English Language Arts and Mathematics tests from the Smarter Balanced Assessment Consortium (SBAC) for the Idaho Standard Achievement Tests (ISAT). ISAT results have been have been reported almost exclusively as "percent proficient" statistics (i.e., the percentage of Idaho students who performed at the "A" level…

Gender achievement gaps on national and state assessments have been a popular research topic over the last few decades. Many prior studies examine these gaps in different subjects (e.g., mathematics, reading, and science) and grades (typically kindergarten through eighth grade) for students living in various regions (typically states or countries)…

The aim of this study is to determine how the TIMSS mathematics success of the 8th grade students differentiates according to the school type, gender, mathematics report mark, parents' education level, cognitive domains and cognitive domains by gender. Relational survey method was used in the study. Six-hundred fifty two 8th grade students…

This study examined children's trajectories of mathematics and reading achievements from kindergarten to eighth grade along with the gender differences in these trajectories. A total of 8503 participants drawn from the Early Childhood Longitudinal Study-Kindergarten Cohort (ECLS-K) formed the sample of the study. The results of the latent growth…

In response to a request for additional analyses, in particular reporting confidence intervals around the results, we re-analyzed the data from prior studies. This supplementary report presents the results of the additional analyses addressing classification accuracy, reliability, and criterion-related validity evidence. For ease of reference, we…

Achievement disparities between American Indian students and non-American Indian peers are persistent and well documented. Student engagement is a promising target for intervention given its relation to academic achievement. This study investigated the relation between specific teacher practices (opportunities to respond [OTRs], praise, and…

This study investigated the relationship between listening comprehension and reading comprehension to determine if environmental factors might be contributing to a possible change in the equalization age for these two comprehension modalities from what was theorized by Thomas Sticht. The study employed a counterbalanced design to measure the…

The purpose of this paper is to showcase new research that seeks to provide guidance on the heterogeneity of treatment effects by utilizing the variance of demographic differences in state assessments. This study is focused on a simple randomized block design where students are nested within schools, and within each school students are randomized…

Past research has investigated the development of stereotypes surrounding race and gender in children; however, there is a lack of literature examining the development of children's stereotypes of older adults. In this study, 163 children from four grades: first (n = 44), fourth (n = 49), fifth (n = 35), and eighth (n = 35) completed a new…

Many studies have found gender differences in certain areas of academic achievement, such as reading and math. Fewer studies have examined gender disparities in writing skills. The current study explored gender differences in written expression performance. Participants were 1,240 male and female students in third through eighth grade,…

We examined the moderating effect of guilt on the associations between moral disengagement and bullying, defending and outsider behaviors in a sample of 404 students (203 boys; M[subscript age] = 11.09 years; SD = 1.48). Bullying, defending and outsider behavior were assessed through peer nominations, whereas guilt and moral disengagement were…
