Quality Indicators for Group Experimental and Quasi-Experimental Research in Special Education

This article presents quality indicators for experimental and quasi-experimental studies for special education. These indicators are intended not only to evaluate the merits of a completed research report or article but also to serve as an organizer of critical issues for consideration in research. We believe these indicators can be used widely, from assisting in the development of research plans to evaluating proposals. In this article, the framework and rationale is explained by providing brief descriptions of each indicator. Finally, we suggest a standard for determining whether a practice may be considered evidence-based. It is our intent that this standard for evidenced-based practice and the indicators be reviewed, revised as needed, and adopted by the field of special education.

Teaching Vocabulary During Shared Storybook Readings: An Examination of Differential Effects.

A storybook intervention for kindergarten children that integrates principles of explicit vocabulary instruction within the shared storybook reading experience is described with findings from an experimental study demonstrating the effects of this intervention on the vocabulary development of kindergarten students at risk of reading difficulty. Results indicated that in comparison to students in the control group, students in the intervention with lower receptive vocabulary skills demonstrated greater gains in explicitly taught vocabulary than did students with higher receptive vocabulary. Findings suggest that the explicit teaching of word meanings within storybook readings may help to narrow, or at least halt, the widening vocabulary gap among students.

VOCABULARY INTERVENTION FOR KINDERGARTEN STUDENTS: COMPARING EXTENDED INSTRUCTION TO EMBEDDED INSTRUCTION AND INCIDENTAL EXPOSURE

The purpose of the two studies reported in this article was to evaluate the effectiveness of extended vocabulary instruction during storybook reading with kindergarten students within a small-group intervention setting. Extended vocabulary instruction is characterized by explicit teaching that includes both contextual and definitional information, multiple exposures to target words in varied contexts, and experiences that promote deep processing of word meanings. In Study One, we compared extended instruction of target words to incidental exposure. In Study Two, we compared extended instruction to embedded instruction (i.e., providing simple definitions within the context of the story). Our findings indicated that extended instruction resulted in greater word learning than either incidental exposure or embedded instruction. Moreover, students maintained much of their understanding of word meanings six to eight weeks after instruction. Implications are discussed in relation to a tri-level approach to vocabulary instruction and intervention for kindergarten students at risk for language and reading disabilities.

Direct Vocabulary Instruction in Kindergarten: Teaching for Breadth versus Depth

The purpose of this study was to compare 2 methods for directly teaching word meanings to kindergarten students within storybook read‐alouds that varied in instructional time and depth of instruction along with a control condition that provided students with incidental exposure to target words. Embedded instruction introduces target word meanings during storybook readings in a time‐efficient manner. Extended instruction is more time intensive but provides multiple opportunities to interact with target words outside the context of the story. Participants included 42 kindergarten students who were taught 9 target words, 3 with each method. Target words were counterbalanced in a within‐subjects design. Findings indicated that extended instruction resulted in more full and refined word knowledge, while embedded instruction resulted in partial knowledge of target vocabulary. Implications are discussed in relation to the strengths and limitations of different approaches to direct vocabulary instruction in kindergarten and the trade‐offs between instruction that focuses on teaching for breadth versus depth.

Indexing Response to Intervention A Longitudinal Study of Reading Risk From Kindergarten Through Third Grade

In this study, response to intervention and stability of reading performance of 41 kindergarten children identified as at risk of reading difficulty were evaluated from kindergarten through third grade. All students were assessed in the fall of each academic year to evaluate need for intervention, and students who fell below the 30th percentile on criterion measures received small-group supplemental intervention. Measures included a combination of commercial normative referenced measures and specific skill and construct measures to assess growth or change in reading risk status relative to 30th percentile benchmarks. Results indicated that consistent with the findings of prior research involving students with comparable entry-level performance, the majority of children identified as at risk in the beginning of kindergarten responded early and positively to intervention. On average, absolute performance levels at the end of kindergarten positioned students for trajectories of later reading performance that exceeded the 50th percentile on the majority of measures. Moreover, changes in risk status that occurred early were generally sustained over time. Only oral reading fluency performance failed to exceed the 30th percentile for the majority of students.

Direct and Extended Vocabulary Instruction in Kindergarten: Investigating Transfer Effects

Abstract The purpose of this study was to investigate the efficacy of an 18-week program of direct and extended vocabulary instruction with kindergarten students on both proximal measures of target word knowledge and transfer measures of generalized language and literacy. A second purpose was to examine whether treatment effects would be moderated by initial receptive vocabulary knowledge measured at pretest. In a quasi-experimental design, 80 kindergarten students from schools serving large at-risk populations were taught the meanings of 54 vocabulary words within interactive story read alouds over 36 half-hour instructional lessons (2 lessons per week over 18 weeks). An additional 44 students served as a no-treatment control. Findings indicated that students who received vocabulary instruction outperformed controls on a measure of target word knowledge as well as measures of generalized receptive vocabulary and listening comprehension. In addition, initial receptive vocabulary was strongly related to posttest performance on all measures. Implications are discussed in relation to supporting vocabulary development in the early grades within a multitier framework of instruction and intervention.

Using Planned Enrichment Strategies with Direct Instruction to Improve Reading Fluency, Comprehension, and Attitude toward Reading: An Evidence‐Based Study

In this study, we used a randomized design to investigate the effects of an enriched reading program on 226 urban elementary students’ (third through sixth grade) reading comprehension, oral reading fluency, and attitude toward reading in 2 elementary schools. The Schoolwide Enrichment Model in Reading Framework (SEM‐R) provides enriched reading experiences by exposing students to books in their areas of interest, daily supported independent reading of challenging self‐selected books using differentiated reading instruction, and interest‐based choice opportunities in reading. Prior to the study, a daily 1‐hour afternoon remedial literacy program was mandated by the district using workbooks and test‐preparation instruction in an attempt to increase reading scores. In the study, 14 teachers were randomly assigned to teach the treatment or a control group during this afternoon literacy block, and students were randomly assigned either to participate in the SEM‐R treatment group or to a control group that continued to receive remedial reading instruction and test preparation for 12 weeks. In addition, all students participated in the direct instructional approach, Success for All, for 90 minutes each morning. Results on oral reading fluency tests and attitudes toward reading scales indicated that students in the SEM‐R treatment group scored statistically significantly higher than control students in both oral reading fluency and attitude toward reading.

A Schoolwide Model for Service Delivery Redefining Special Educators as Interventionists

General and special education are confronting tremendous change resulting from legal mandates related to closing the achievement gap under No Child Left Behind and a focus on early intervention and prevention in the Individuals With Disabilities Education Act, 2004. As a result, schoolwide intervention approaches are under rapid development, evaluation, and implementation across the country. Based on these approaches, the authors present a conceptual model for redefining special educators as interventionists who focus on the adoption and use of evidence-based, schoolwide academic and behavioral interventions. Examples of the roles and responsibilities for interventionists within the schoolwide model are provided.

Teaching Vocabulary to First-Grade Students Through Repeated Shared Storybook Reading: A Comparison of Rich and Basic Instruction to Incidental Exposure

The purpose of this study was to evaluate effectiveness of rich and basic instruction to incidental exposure of target words with first-grade students within the context of repeated shared storybook reading. Participants were 224 first-grade students, randomly assigned to a condition by classroom, from three elementary schools that serve large numbers of students at-risk for experiencing reading difficulties. All three conditions received large group instruction of the storybook intervention in three 20–30 minute sessions over the course of one week. Results indicated that rich instruction was superior to both basic and incidental exposure across all taught measures. These results were maintained at delayed post-test three weeks following the conclusion of the intervention. Implications are discussed in relation to a three-step approach to vocabulary instruction.

Direct Instruction of Comprehension: Instructional Examples From Intervention Research on Listening and Reading Comprehension

This article examines the role of direct instruction in promoting listening and reading comprehension. Instructional examples from 2 programs of intervention research focused on improving comprehension; the Story Read Aloud Program and the Embedded Story Structure Routine are used to illustrate principles of direct instruction. An analysis of these 2 approaches suggests that direct instruction principles are effective in supporting students with varied achievement levels and that these principles can be used to enhance comprehension among students at very different points in reading development. These evidence-based approaches also illustrate that direct instruction can be designed to support complex learning and the development of higher order cognitive strategies.
