We present experimental evidence on the impact of a multi-faceted program that integrates technology-aided instruction, teacher training and coaching, community ownership, and free primary education. Our setting is three districts in rural Zambia, where we randomly assigned the program across 30 treatment and 33 control schools. The results show…

We use data from a large-scale, school-level randomized experiment conducted in 2010-2011 in public schools in Indiana. Our sample includes more than 30,000 students in 70 schools. We examine the impact of two interim assessment programs (i.e., mCLASS in Grades K-2 and Acuity in Grades 3--8) on mathematics and reading achievement. Two-level models…

The purpose of this replication study was to examine the impact of the Teacher Study Group (TSG) professional development in vocabulary on first-grade teachers' knowledge of vocabulary instruction and observed teaching practice, and on students' vocabulary knowledge. Sixty-two schools from 16 districts in four states were randomly assigned to…

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)…

In this paper, we describe findings from a three-year evaluation of a well-developed mathematics professional development program that is commercially available on a wide scale. The professional development is designed to improve teachers' mathematical knowledge for teaching and to enable them to elicit more student thinking and reasoning during…

Multitiered systems of reading instruction and intervention, including response to intervention, are widely used in early reading by schools to provide more intense services to students who need them. Research using randomized controlled trials has compared innovative Tier 2 interventions to business-as-usual Tier 2 approaches and established a…

National reports reveal one third of American fourth graders read below basic level on measures of comprehension. One critical component of comprehension is fluency: rapid, accurate, expressive reading with automaticity and prosody. Many fluency studies and classroom interventions focus only on reading rate, but this alone is not sufficient. This…

The purpose of this varied replication study was to evaluate the effects of a supplemental reading intervention on the beginning reading performance of kindergarten students in a different geographical location and in a different instructional context from the initial randomized trial. A second purpose was to investigate whether students who…

Results from randomized controlled trials of learning strategies instruction with 375 adult basic education participants are reported. Reading outcomes from whole group strategic instruction in 1 of 4 learning strategies were compared to outcomes of reading instruction delivered in the context of typical adult education units on social studies,…

This article reports the results from a randomized control field trial that investigated the impact of an enhanced decoding and spelling curriculum on the development of adult basic education (ABE) learners' reading skills. Sixteen ABE programs that offered class-based instruction to Low-Intermediate-level learners were randomly assigned to either…

We examined the extent to which strategies instruction, using the Self-Regulated Strategy Development (SRSD) model, would enhance the writing, engagement during writing, and behavior of 44 second-grade students identified as having behavioral and writing difficulties. This study occurred within a comprehensive, integrated, three-tiered model of…

The purpose of the current study was to test the efficacy of a supplemental phonological awareness focused intervention delivered by community-based paraeducators with preschool children (M = 4.73 years) in eight Head Start classrooms in the rural Midwest. Participating children were randomly assigned to small groups within classrooms, which were…
