In collaboration with an urban public school, teacher candidates at a nearby university created a social-emotional skills project called Knight Brigade. The author discusses the project planning, implementation, and results as part of this ongoing partnership.

Both early childhood maternal language input and the quality of classroom instruction in elementary school have been shown to be important environmental supports in predicting children's literacy skill development. However, no studies have simultaneously examined these two environmental supports in relation to children's early language skills and…

This instrumental mixed methods case study investigated Grades 3-5 classroom teachers' perceptions of teaching for creativity and the effects of a researcher-developed, one-day, online professional development creativity module intervention within a suburban school district in south-central Pennsylvania. Creativity has been identified as a…

Although the promise of universal social-emotional learning (SEL) programs enhancing student academic outcomes has captured public attention, there has been limited research regarding such programs' impact on students' state test scores. We used multilevel modeling of follow-up data from a multiyear, multisite cluster-randomized efficacy trial to…

This article reports the results from a study investigating the effects of a discipline-specific reading and writing intervention (I3C/PROVE IT!) with fourth and fifth graders. Participants included 237 students with writing difficulties (WD) from an initial pool of 608 upper elementary school students in a larger study. Teachers and students were…

Fluency, vocabulary building, making inferences, expanding background knowledge, and metacognitive thinking are reading skills taught in schools across the country. Which of these do ELA teachers consider to be most important? It is not known which of these five areas Western Pennsylvania teachers believe has the most impact on comprehension…

Purpose: A growing trend in instructional improvement efforts is the use of formative assessment informed by research-based developmental trajectories of how students gain deeper understanding of subject matter content over time. This article reports the findings of a large-scale experimental study of an innovative mathematics professional…

Few longitudinal studies examine how "changes" in parent-child relationships are associated with changes in youth internalizing problems. In this longitudinal study, we investigated how developmental trends (linear change) and year-to-year lability (within-person fluctuations) in parental warmth and hostility across Grades 6 to 8 predict…

Antisocial peer behavior and low parental knowledge of adolescents' activities are key interpersonal risk factors for adolescent substance use. However, how the magnitude of associations between these risk factors and substance use may vary across adolescence remains less well understood. The present study examined the age-varying associations of…

Many students' knowledge of fractions is adversely affected by whole number bias, the tendency to focus on the separate whole number components (numerator and denominator) of a fraction rather than on the fraction's integrated magnitude (ratio of numerator to denominator). Although whole number bias appears early in the fraction learning process…

This study investigated the low literacy and math achievement of 4th grade students with emotional disturbances (ED) in an urban school district in Pennsylvania. Researchers have speculated that teachers possess limited knowledge of the behavioral health needs of students with ED needed to support their behavior and achievement. Therefore, this…

Teacher research (practitioner inquiry) is an effective form of professional development for middle level teachers. Through teacher research, classroom teachers develop the skills needed to demonstrate mastery of the performance standards for middle level master teacher candidates. Using well-established research methods, middle level educators…

After serving as a high school math teacher in Maryland for three years, the author moved to teaching sixth-grade math. His high school background led him to differentiate differently than his colleagues. The article discusses his observations and his conclusions and offers a plan to implement changes in the way mathematics is taught through…

We examined developmental and individual differences in 6th and 8th graders' fraction arithmetic and overall mathematics achievement and related them to differences in understanding of fraction magnitudes, whole number division, executive functioning, and metacognitive judgments within a crosssectional design. Results indicated that the difference…
