Research tells us that students who experience difficulty reading in the early years of school often struggle to catch up (Stanley, Petscher, & Catts, 2018; Ozernov,, Palchik et al., 2016; Cunningham & Stanovich, 1997; Francis, Shaywitz, Stuebing, Shaywitz, & Fletcher, 1996) . This study1 focuses on an innovative curriculum for kindergarten that closely integrates literacy instruction and science exposure. The research study combines a rigorous randomized controlled trial with in-depth cost and implementation studies to investigate impacts.  \nThe setting: An urban district focused on literacy  \nThe study’s setting—the School District of Philadelphia (SDP)—makes this inquiry particularly salient. SDP is a large, urban district serving a diverse and economically challenged student population. Decades-long trends of underperformance in literacy have led SDP to prioritize and invest in early literacy. This study offers a comparison of two approaches to evidenced-based literacy instruction implemented in SDP schools—a business-as-usual approach and a curriculum that includes science integration.  \n1 The research reported here was supported by the Institute of  \nResearch Design  \n• Multi-site randomized controlled study inv","cbCaiqT515LZpZvg","https://ap.wps.com/l/cbCaiqT515LZpZvg","pdf",455158,"English","# Introduction\n# The setting: An urban district focused on literacy\n# Research design\n## Multi-site randomized controlled study\n# Kindergarten impacts\n## Zoology One students","[{\"question\":\"What is the main purpose of the study described in the policy brief?\",\"answer\":\"The study evaluates impacts of a kindergarten curriculum that integrates literacy instruction with science exposure, assessing outcomes alongside cost and implementation considerations.\"},{\"question\":\"Where was the research conducted and why is the setting emphasized?\",\"answer\":\"Research was conducted in the School District of Philadelphia, an urban district with a diverse and economically challenged student population and long-standing literacy underperformance.\"},{\"question\":\"What was the research design and what data were collected?\",\"answer\":\"It used a multi-site randomized controlled trial comparing Zoology One in treatment classrooms with business-as-usual literacy instruction in control classrooms, collecting data across 71 classrooms in 21 schools for two kindergarten cohorts.\"}]","Zoology One Efficacy Evaluation Summary of Findings - April 2020 | PDF",1792047830]
