This study investigated the application of item response theory (IRT) to expand the range of ability estimates for gifted (hereinafter referred to as high-achieving) students' performance on an above-level test. Using a sample of fourth- to sixth-grade high-achieving students (N = 1,893), we conducted a study to compare estimates from two…

Social cognitive career theory (SCCT) and the theories of reasoned action and planned behaviour (TRAPB) have both guided studies seeking to explain students' intentions and decisions related to future science engagement. The purpose of this study was to simultaneously validate measures for these two social psychological models and closely examine…

We used the Stanford education data archive (SEDA) data to examine the heterogeneity among urban school districts in the United States. The SEDA 2.1 includes data sets on students' mathematics (Math) and English language arts (ELA) achievement from 2008 to 2014 at the district level. Growth mixture modeling was used to uncover the underlying…

The purpose of this study was to investigate the effectiveness of a beginning jazz improvisation learning environment for middle school instrumentalists, including whether one of two instructional sequences of harmonic form improvisation tasks better supported four outcomes: achievement, self-assessment, self-efficacy, and motivation. Over 12…

Four-parameter models have received increasing psychometric attention in recent years, as a reduced upper asymptote for item characteristic curves can be appealing for measurement applications such as adaptive testing and person-fit assessment. However, applications can be challenging due to the large number of parameters in the model. In this…

This study investigated the relationship between task-based teacher training and novice English language teachers' cognitions and implementations of tasks in Honduran bilingual schools. After participating in a four-week training program on task-based language teaching, teachers with little or no prior teaching experience designed task-based…

Using a DisCrit intersectional lens and statistical and spatial methods, we trace how the creation of K-8 schools functioned to create pockets of privilege in one urban U.S. school district. K-8 schools were both whiter and wealthier than district averages, serving as "enclave" schools. Although far fewer students with disabilities were…

The impact of the COVID-19 pandemic continues to overwhelm the functioning and outcomes of educational systems throughout the nation. The public education system is under particular scrutiny given that students, families, and educators are under considerable stress to maintain academic progress. Since the beginning of the crisis, school-systems…

The current scales for self-blame are not suitable for school bullying scenarios and most lack validity. This study used a self-developed scale to measure bullied victims' tendency to self-blame and further examined whether victims and bully/victims exhibited different tendencies toward self-blame under both bullied and generalized scenarios. The…

Carol Dweck's Mindset Theory suggests that a teacher who has a growth mindset believes that a student's basic qualities are things you can cultivate through effort. Dweck's theory explains that by applying a growth mindset towards children, they begin to change the way they take on challenges in their education (Dweck, 2006). One way that…

This study examines the use of cross-classified random effects models (CCrem) and cross-classified multiple membership random effects models (CCMMrem) to model rater bias and estimate teacher effectiveness. Effect estimates are compared using CTT versus item response theory (IRT) scaling methods and three models (i.e., conventional multilevel…

English learners' (ELs) day-to-day experiences in school change when reclassified as fully English proficient. Prior research, however, is mixed on how reclassification influences outcomes. Many studies also do not or cannot explore key long-term outcomes or identify impacts over time. In this study I leverage longitudinal student data in a…

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…

This article reveals inequity as a longitudinal construction involving the cumulation of micro/macroaggressions for children who live in high-poverty communities and attend poorly funded schools. Drawing on critical race theory and empirical research that documents forms of micro/macroaggression, a longitudinal analysis is used to identify forms…

Individual growth curves yield insights about growth that are not available from any other methodology; and developmental scales based on conjoint measurement models provide unique interpretive advantages for investigations of academic growth. The advantages are apparent when: (1) 15 consecutive statewide reading growth curves are annotated with…
