The purpose of this study was to examine the relationship of two implementation variables (source of technical support and time of implementation) to first grade reading achievement across three naturally-occurring conditions over a six-year time span. Two of the conditions involved implementation of Direct Instruction (DI) curriculum programs,…

Present national methodological standards for evaluating the credibility of the design of individual research studies have resulted in findings reporting the pre-­post effectiveness of Direct Instruction programs to be eliminated from consideration by educational leaders involved in making curricular decisions intended to advance local school…

This study used a single-subject multiple probe design to investigate the use of Direct Instruction (DI) to teach students with autism to tell time to the five-minute increment. Exercises from "Connecting Math Concepts" were used as the DI component during intervention. All students increased their telling-time skills to the five-minute…

This paper examines changes in the average mathematics achievement of students in the Baltimore City Public School System (BCPSS) from 1998 to 2003, comparing students in schools that implemented Direct Instruction with students in other schools. First-grade students who received Direct Instruction had significantly higher levels of achievement on…

Thirty-seven students from a suburban community in the southern United States were randomly assigned to receive 30 minutes of additional instruction each day in their usual language arts curriculum or 30 minutes of instruction with the Direct Instruction program, "Funnix Beginning Reading". Instruction for the "Funnix" group…

Effective written expression is a necessary form of communication and one of the most difficult tasks for students with disabilities to master. Few instructional strategies for writing have been validated specifically for students with emotional and behavior disorders. This single-subject study evaluated the effect of a Direct Instruction program…

This study investigated whether the use of "Spelling Through Morphographs" (Lessons 1-45) designed for grade 3-adult students could be effective when implemented in an above-average educational setting with grade 2 students. Using a cross-grade, longitudinal design, designed to provide a methodological foundation for addressing the acceleration of…

Students with high-incidence disabilities struggle with reading comprehension due to difficulties in background knowledge and metacognitive skills, including use of self-monitoring and other strategies. In the United States, these students typically receive the majority of their instruction in general education settings. However, there is little…

This study examined the effects of a Direct Instruction (DI) reading program combined with Precision Teaching during a public school's summer program. Students received instruction from "Reading Mastery" programs for a six-week period. Students also practiced specific reading skills including letter-sound identification, sounding out…

This paper illustrates an approach for Direct Instruction (DI) practitioners and researchers for enhancing the value of DI implementations beyond that obtained through student test performance alone. The importance of such enhancements is based on perspectives from scale-up research linking intervention value with sustainability. In this study,…

Building on research showing the interdependence of language skills and reading proficiency, this study examined the effects of using the "Language Arts" strand of the "Reading Mastery Signature" 2008 series program as a supplement to non-Direct Instruction reading programs with English Language Learner (ELL) students.…

Although "Corrective Reading Decoding" has been validated as effective over a wide range of students, there is a lack of information on its effectiveness with older students having intellectual and developmental disabilities (IDD). Thus, the purpose of this investigation was to determine the effectiveness of "Corrective Reading…

This study explored the effects of "Reading Mastery Plus" in grades K-2 at a Title 1 school with six students with intellectual and developmental disabilities (IDD). Two students in each of grades kindergarten, 1, and 2 participated. "Diagnostic Indicators of Basic Early Literacy Skills (DIBELS)" spring fluency probes were used…

In a three-part study we explored implications for enhancing the role of "Corrective Reading" ("CR") in systemic school reform relating to teacher judgments of the high levels of student academic performance required by "CR" tasks in contrast to inappropriate instructional perspectives applied by teachers regarding…
