We explored third- to fifth-grade children's friendship concepts in 20 autistic and 21 nonautistic students matched for mental age. Transcripts of semi-structured interviews were coded for definitions of friendship, friendship expectations, and friendship transgressions (i. e., violations of friendship expectations), and subjected to quantitative…

We published our first set of Connections Academy efficacy reports containing independently assured efficacy statements in 2018. We went on to build on that body of research, and updated our reporting with new findings in 2021. Our latest study compared Connections Academy students' state test scores in reading and math with students in…

Elementary school students in today's urban classrooms face many life circumstances at home and in their communities that contribute to stress and coping needs. These stressors are often brought into the classroom, which impact learning, behaviors, and overall academic performance. Mindfulness has been used in classroom settings, particularly with…

To understand the immediate impact of a university-school district partnership that places preservice teachers (both traditional undergraduates and graduate students in an initial licensure residency program) in a Professional Development School (PDS) model, this exploratory study reviewed data from yearly examinations required by the Kansas State…

The study examined the effect of charter school attendance on annual student achievement growth in math and reading. The research described in this report meets WWC evidence standards with reservations. WWC Rating Strengths: The study matched charter school students with similar students in traditional public schools using demographic and academic…

Because random assignment is not possible in observational studies, estimates of treatment effects might be biased due to selection on observable and unobservable variables. To strengthen causal inference in longitudinal observational studies of multiple treatments, we present 4 latent growth models for propensity score matched groups, and…

This study examined academic differences between students who attended 21st Century Community Learning Center (CCLC) programs frequently (60 or more days) and matched nonattendees during the 2008-2009 school year. Schools included in the study represented only those centers found to be implementing high-quality programming, as measured by a…

This study looks at the question of whether charter schools are more innovative in their provision of extended time policies than a matched set of traditional public schools. Data for this study was collected from a sample of traditional public and charter schools that partner with the Northwest Evaluation Association (NWEA) for interim…

The ability to identify stop consonants from brief onset spectra was compared between a group of Chinese children with phonological dyslexia (the PD group, with a mean age of 10 years 4 months) and a group of chronological age-matched control children. The linguistic context, which included vowels and speakers, and durations of stop onset spectra…

There are several goals guiding this study. First, the authors use an experimental design to examine the causal effects of giving children 10 self-selected books over two summers. Second, they examine whether treatment effects are moderated by children's family income (i.e., eligibility for free- and reduced-price lunch). As a result, they examine…

The purpose of this study was to (a) evaluate and discuss strengths and weaknesses in the current system of identifying gifted students and (b) investigate the effectiveness of using the Naglieri Nonverbal Abilities Test to identify underrepresented and gifted minority students in grades one through five in Central Mississippi. The study consisted…

To evaluate whether performance differences between good and poor readers relate to reading-specific cognitive factors that result from engaging in reading activities and other experiential factors, the authors gave students in Grades 4 and 6 a perceptual identification test of words not only drawn from their personal lexicon but also varying in…

A long-awaited federal study of reading and math software found no significant differences in standardized-test scores between students who used the technology in their classrooms and those who used other methods. The study compared classes overseen by teachers who used the technology-based products with those of other teachers who used different…

This study investigated the influence of cognitive and linguistic skills on the reading comprehension performance of a group of learners from diverse linguistic backgrounds. The study also compared the reading comprehension performance of grade 4 children who entered kindergarten with little or no experience with English (ESL) to that of a group…
