This article describes the effects of an analysis-of-practice professional development (PD) program on elementary school students' (Grades 4-6) science outcomes. The study design was a cluster-randomized trial with an analysis sample of 77 schools, 144 teachers and 2,823 students. Forty-two schools were randomly assigned to treatment, (88.5 hours)…

Most U.S. classrooms serve students with various linguistic and academic needs. Tier-I universal approaches support English language learners (ELLs) without segregating them into a different track and thereby constraining future learning opportunities. The current study examines whether Word Generation (WG), a Tier-I discussion-based program…

The recent wave of test-based accountability reforms has negatively impacted the provision of K-12 arts educational experiences. Advocates contend that, in addition to providing intrinsic benefits, the arts can positively influence academic and social development. However, the empirical evidence to support such claims is limited. We conducted a…

The purpose of this evaluation of Scholastic's "System 44" conducted by RMC Research was to expand the existing research on students with learning disabilities by conducting a randomized study of struggling readers with approximately half of the sample comprised of students with learning disabilities. Specifically, this evaluation…

Scholastic's "System 44" is a foundational reading program intended for older struggling readers who have not mastered basic phonics and decoding skills. Combining researched-based phonics instruction with adaptive technology, "System 44" is designed to improve students' word reading accuracy, fluency, and comprehension. The…

Background: Knowledge of concepts and procedures seems to develop in an iterative fashion, with increases in one type of knowledge leading to increases in the other type of knowledge. This suggests that iterating between lessons on concepts and procedures may improve learning. Aims: The purpose of the current study was to evaluate the…

The goal of this study was to assess the effectiveness of an intervention--Quality English and Science Teaching (QuEST)--designed to develop the science knowledge and academic language of middle grades English language learners studying science in their second language and their English-proficient classmates. Both English language learners and…

Proposes that conceptual and procedural knowledge develop in an iterative fashion and improved problem representation is one mechanism underlying the relations between them. Two experiments were conducted with 5th and 6th grade students learning about decimal fractions. Results indicate conceptual and procedural knowledge do develop, iteratively,…

The effects of a revising goal to "add information" on revising behavior and writing performance were examined for 70 5th and 6th graders. Students assigned the goal made more meaning-based changes and produced improved text quality. Procedural assistance did not appreciably enhance revising behavior or text quality. (SLD)

Trial spanning grades 1-4 reported changes in classroom processes produced by ClassWide Peer Tutoring (CWPT) Program covaried with statistically and educationally significant levels of growth in at-risk students' academic achievement. Investigated follow-up outcomes at end of sixth grade. Found continued improved academic outcomes in students at…
