We examined to what extent subgroups of students identified with learning disabilities (LDs; N = 630) in the Early Childhood Longitudinal Study, Kindergarten Class of 1998 to 1999 (ECLS-K): 1998 national longitudinal study displayed heterogeneity in longitudinal profiles of reading and mathematics achievement from first to eighth grades.…

Academic underachievement, as measured on standardised assessments, is commonly reported among students on the autism spectrum. However, little is known about the factors that predict academic (under)achievement, limiting the development of effective and targeted interventions. This study explored teacher ratings of academic skills and enabling…

This study examines associations between leisure reading and reading skills in data of 2,525 students followed from age 7 to 16. As a step further from traditional cross-lagged analysis, a random intercept cross-lagged panel model was used to identify within-person associations of leisure reading (books, magazines, newspapers, and digital…

It has been common knowledge for decades that poor and working-class students tend to experience "summer learning loss," a drop in performance between spring and fall that serves to widen the gap between students. However, new research shows that the reality of summer learning loss is more complex. Megan Kuhfeld draws on data from the…

We examined the age of onset, over-time dynamics, and mechanisms underlying science achievement gaps in U.S. elementary and middle schools. To do so, we estimated multilevel growth models that included as predictors children's own general knowledge, reading and mathematics achievement, behavioral self-regulation, sociodemographics, other child-…

The purpose of this report was to measure the effect of the Baylor College of Medicine Summer Science Institute (BCMSSI) on science performance of students whose teachers participated in the program during summer 2013. Paired t-test results showed statistically significant increases in the BCM students' Stanford 10 science performance at the…

The purpose of this study was to measure the effect of the Baylor College of Medicine Summer Science Institute (BCMSSI) on teacher science content knowledge and students' science performance. The analysis of the effect of participation showed an increase of 253 scale score points on the 2015 State of Texas Assessments of Academic Readiness,…

The purpose of this evaluation was to measure the impact of the Baylor College of Medicine (BCM) Summer Institute on science performance of students whose teachers participated during the summers of 2011 and 2012. Paired t-tests revealed statistically significant increases in a sample of elementary students' Stanford 10 science scores at 3rd…

The development of English language learners (ELLs) was explored from kindergarten through eighth grade within a nationally representative sample of first-time kindergartners (N = 19,890). Growth curve analyses indicated that, compared to native English speakers, ELLs were rated by teachers more favorably on approaches to learning, self-control,…

The purpose of this study was to examine the characteristics and predictive factors for children receiving special education services, and if they received special education services, factors associated with them discontinuing those services before eighth grade. In addition, a second purpose was to determine whether there are differences in the…

Studies of student risk of school dropout have shown that present predictors of at-risk status do not accurately identify a large percentage of students who eventually drop out. Through the analysis of the entire Grade 1-12 longitudinal cohort-based grading histories of the class of 2006 for two school districts in the United States, the author…

This study examined the longitudinal relationship of early elementary predictors to adolescent depression 7 years later. The sample consisted of 938 students who have been part of a larger longitudinal study that started in 1993. Data collected from parents, teachers, and youth self-reports on early risk factors when students were in 1st and 2nd…

Study 1 retrospectively analyzed neuropsychological and psychoeducational tests given to N = 220 first graders, with follow-up assessments in third and eighth grade. Four predictor constructs were derived: (1) Phonemic Awareness, (2) Picture Vocabulary, (3) Rapid Naming, and (4) Single Word Reading. Together, these accounted for 88%, 76%, 69%, and…
