"Open Court Reading"[c] is a core reading program for grades K-6 developed by SRA/McGraw-Hill that is designed to teach decoding, comprehension, inquiry, and writing in a logical progression. Part 1 of each unit, Preparing to Read, focuses on phonemic awareness, sounds and letters, phonics, fluency, and word knowledge. Part 2, Reading and Responding, emphasizes reading literature for understanding, comprehension, inquiry, and practical reading applications. Part 3, Language Arts, focuses on writing, spelling, grammar, usage, mechanics, and basic computer skills. SRA/McGraw-Hill revised "Open Court Reading"[c] and changed the name to "Imagine It!"[c] in 2007. Fifty-eight studies reviewed by the What Works Clearinghouse (WWC) investigated the effects of "Open Court Reading"[c] on adolescent readers. One study (Borman, Dowling, & Schneck, 2008) that falls within the scope of the Adolescent Literacy review protocol is a randomized controlled trial and meets WWC evidence standards without reservations. The study included more than 900 first-grade through fifth-grade students who attended five schools located in five states across the United States. Based on this study, the WWC considers the extent of evidence for "Open Court Reading"[c] on adolescent readers to be small for one domain: comprehension. The study is described in this report. The remaining 57 studies do not meet either WWC eligibility screens or evidence standards. A glossary of terms is included. Appended are: (1) Research details for Borman et al., 2008; (2) Outcome measures for each domain; (3) Findings included in the rating for the comprehension domain; and (4) Supplemental subtest findings for the comprehension domain. (Contains 4 tables, 7 endnotes and 2 additional sources.) [For the 2008 Intervention Report on this program, see ED502267.]
