WWC Summary of Evidence for this Intervention
Houghton Mifflin Reading©
A reading program for instruction in grades K–6. It uses Big Books (authentic literature), anthologies, Read Alouds, and audio compact discs to provide step-by-step instruction in reading. According to the developer’s website, Houghton Mifflin Reading© was developed based on the findings of the National Reading Panel. The product is designed to be used as a full-year curriculum program with instruction on developing oral language and comprehension, phonemic awareness, decoding skills (phonics, analogy, context, and word recognition), fluency, reading comprehension, writing, spelling, and grammar. Instruction is organized by a set of themes (10 for grades K–1 and 6 for grades 2–6) with selected Big Books (fiction and non-fiction literature) and other classroom activities to highlight the theme.
