The purpose of this study was to determine the extent to which tri-weekly evidence-based vocabulary lessons implemented throughout the regular school day would increase kindergarten students' expressive and receptive vocabulary development, thus decreasing the vocabulary gap exhibited between low-income children and their more advantaged peers…

There is limited research demonstrating direct instruction (DI) as an effective language intervention for students with autism spectrum disorders (ASD) and developmental disabilities (DD). Existing research has shown that instruction using partial implementation of DI programs resulted in student learning (Ganz, 2007) and instruction using whole…

The purpose of this study was to investigate the effectiveness of explicit, direct, and generative strategy training and working memory capacity (WMC) on mathematical word problem-solving accuracy in elementary schoolchildren. In this study, children in third grade ("N" = 82) identified as at risk for math difficulties (MD) were randomly…

The widespread adoption of the Common Core State Standards (2010) has caused mathematics and special educators to reconsider instructional methods. The Common Core introduces eight Standards for Mathematical Practice that outlines the dispositions that should be fostered in students. Most notable are those that push students to analyze problems,…

Students with emotional and behavioral disorders (EBD) are known to experience academic deficits across core subject areas such as reading and mathematics. Until recently, less attention had been paid to the academic deficits of students with EBD. This was due, in part, to a common belief that academic deficits could not be addressed until problem…

Attention deficit/hyperactivity disorder is a common developmental disorder that can cause a motor-skill delay in children. Positive illusory bias (PIB)--the belief that one is better at performing a task or a skill than one actually is--may be one cause of this delay. Although nearly everyone experiences a mild and healthy PIB, students with ADHD…

In a study with ninth-grade mathematics students on learning the concept of variance, students experienced either direct instruction (DI) or productive failure (PF), wherein they were first asked to generate a quantitative index for variance without any guidance before receiving DI on the concept. Whereas DI students relied only on the canonical…

Successful academic writing requires strong command of the rhetorical moves that orient the reader to the theme and substantive material of an academic essay. Effective control of the introduction leads to better overall writing. The goal of this study was to devise and evaluate a pedagogy for teaching the writing of academic essay introductions.…

"Reading Mastery" is designed to provide explicit reading instruction to students in grades pre-K-5. One of several Direct Instruction curricula from McGraw-Hill, "Reading Mastery" is available in two versions: (1) "Reading Mastery Classic" (for grades pre-K-2) aims to help beginning readers identify letter sounds,…

The goal of the current study was to compare two forms of dynamic assessment and standard assessment of preschool children's phonological awareness. The first form of dynamic assessment was a form of scaffolding in which item formats were modified in response to an error so as to make the task easier or more explicit. The second form of dynamic…

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,…

Some students with intellectual disabilities require explicit instruction of language skills, including preposition use; however, little is known about effective ways to teach preposition use to this population. This study examined direct instruction (DI) to teach students to use and respond to prepositions. Results indicated that DI was an…

Background: Cooperative Learning (CL) is an inclusive name for various models of teaching/learning methods, all of which emphasize the fundamental of meaningful collaboration among learners during their learning activities. Purpose: The purpose of this study was to examine whether the CL teaching model contributed to the teaching efficacy and…

This report outlines a 2-year investigation into how secondary science teachers used professional development (PD) to build scientific classroom discourse communities (SCDCs). Observation data, teacher, student, and school demographic information were used to build a hierarchical linear model. The length of time that teachers received PD was the…

The purpose of this study was to determine the effectiveness of a Direct Instruction summer reading intervention program designed to minimize summer reading regression. The summer intervention program targeted the lowest quartile of readers in grades kindergarten through third grade from a suburban school district over a three-week period before…
