The prominent use of DIBELS as a screening and placement tool has provided schools and districts the ability to implement interventions and best practices for students, particularly in the primary grades. Although many studies have highlighted the predictive validity of oral reading fluency (ORF) to anticipate reading performance, few have extended that research to examine the performance of ethnic and economic subgroups as compared to non-minority peers. Disaggregating the data to study specific populations can expose whether ORF's relationship with reading comprehension depends on group membership and ultimately improve the quality of the assessment. This study examines the predictive validity of DIBELS ORF for two types of comprehension scores within a racially and ethnically diverse second grade cohort.

abstract: Recent legislation allowing educational agencies to use Response to Intervention (RTI) in determining whether a child has a specific learning disability, coupled with a focus on large-scale testing and accountability resulted in the increasing use of curriculum based measurement (CBM) as a tool for understanding students' progress towards state standards, particularly in reading through the use of oral reading fluency measures. Extensive evidence of oral reading fluency's predictability of reading comprehension exists, but little research on differential effects across racial, gender, and socioeconomic subgroups is available. This study investigated racial, gender, and socioeconomic bias in DIBELS Oral Reading Fluency (DIBELS ORF) probes predictive and concurrent relationship with MAP reading comprehension scores for African American and Caucasian students. Participants were 834 second through fifth grade students in a school district located in a southeastern US state. The dataset consisted of student fall and spring DIBELS ORF scores and spring MAP reading comprehension scores. Concurrent correlation results between spring DIBELS ORF and MAP reading comprehension scores were moderate to large and statistically significant across all grades and demographic groups; however, correlations between fall DIBELS ORF and MAP reading comprehension scores were generally weak. Stepwise multiple regression analyses were used to examine the best variable, or combination of variables, in predicting MAP reading comprehension scores. Models differed for each grade level; however, spring DIBELS ORF scores were always included, whether alone or in combination with demographic variables, in the best prediction model. Potthoff's procedure was used to simultaneously test for slope and intercept differences among regression equations to determine if DIBELS ORF scores from fall and spring differentially predicted MAP reading comprehension scores across demographic groups. Nine of 24 simultaneous contrasts demonstrated a significant effect; seven were related to race, one was related to gender, and one was related to socioeconomic status. Racial bias in predicting MAP reading comprehension performance from spring DIBELS ORF was found. Differential prediction among gender and SES groups was not consistent indicating little to no practical significance. Results are discussed in the context of practical implications of differential validity, both predictive and concurrent, and potential impact on disproportionality. / Dissertation/Thesis / Ph.D. Educational Psychology 2013

Exploring the relationship between early oral reading fluency ability and reading comprehension achievement among an ethnically and racially diverse sample of young learners from low-income families, attending elementary school within a large public school district in southeast Florida is the purpose of this longitudinal study. Although many studies have been conducted to address the relationship between oral reading fluency ability and reading comprehension achievement, most of the existing research failed either to disaggregate the data by demographic subgroups or secure a large enough sample of students to adequately represent the diverse subgroups. The research questions that guided this study were: (a) To what extent does early oral reading fluency ability measured in first, second, or third grade correlate with reading comprehension achievement in third grade? (b) To what extent does the relationship of early oral reading fluency ability and reading comprehension achievement vary by demographic subgroup membership (i.e., gender, race/ethnicity, socioeconomic status) among a diverse sample of students? A predictive research design using archived secondary data was employed in this nonexperimental quantitative methods study of 1,663 third grade students who attended a cohort of 25 Reading First funded schools. The data analyzed derived from the Dynamic Indicators of Basic Early Literacy Skills Oral Reading Fluency (DIBELS ORF) measure administered in first, second, and third grades and the Florida Comprehensive Assessment Test of the Sunshine State Standards (FCAT-SSS) Reading administered in third grade. Linear regression analyses between each of the oral reading fluency and reading comprehension measures produced significant positive correlations. Hierarchical regression analyses supported the predictive potential of all three oral reading fluency ability measures toward reading comprehension achievement, with the first grade oral reading fluency ability measure explaining the most significant variance in third grade reading comprehension achievement. Male students produced significant overall differences in variance when compared to female students as did the Other student subgroup (i.e., Asian, Multiracial, and Native American) when compared to Black, White, and Hispanic students. No significant differences in variance were produced between students from low and moderate socioeconomic families. These findings are vital toward adding to the literature of diverse young learners.

This study aimed to provide information about the quality of the evidence on reading fluency instruction for at-risk students and students with reading/learning disabilities as a way to evaluate whether an instructional strategy is evidence-based and has potential for classroom use. An extensive search process with inclusion and exclusion criteria yielded a total of 18 studies to be included in the present study: 12 group design studies and six single-subject design studies. The quality indicators proposed by Gersten et al. (Except Child 71:149–164, 2005) and Horner et al. (Except Child 71:165–179, 2005) were applied to evaluate the quality of selected fluency intervention studies. Results revealed that (a) most group design studies provided little information about the intervention and agent for the comparison group, (b) internal and social validity were not clearly stated in single-subject design studies, and (c) procedural fidelity in assessment and intervention implementation was inadequately addressed in both group design and single-subject design studies. Lack of methodological rigor, which hampers determinations of the effectiveness of fluency instruction, the current status of intervention studies, and future directions are discussed.

A synthesis of the research literature was conducted from 2004 to 2014 on interventions designed to build oral reading fluency for elementary students with learning disabilities (LD). An extensive search yielded a total of 12 intervention studies. Among the 12 studies, the majority (n D 9) implemented repeated reading with or without a model. Findings from this synthesis indicate that there may be no differential effects between repeated reading with or without a model for improving oral reading fluency of elementary students with LD. In addition, findings suggest that elementary students with LD may benefit from video modeling or word/phrase-based practices that provide opportunities to repeat misread words or phrases with words incorrectly read during the initial reading.

This study presents a multicase study that looked at the fluency development of three fourth grade readers of varying reading abilities. The participants were chosen based on two scores, their words correct per minute (WCPM) score and their Multidimensional Fluency Scale score (MFS). The three students participated in an eight-week intervention in which readers theaters were used for fluency instruction and practice. Both qualitative and quantitative methods were used as the researcher observed the students during the literacy block of the day; interviewed the three participants three times; one-on-one, gathered self-report sheets that the participants filled out weekly; and recorded their WCPM and MFS scores weekly. Findings of this study suggest that students' engagement in readers theater helped develop various aspects of fluency: expression, volume, and pace. Motivation and confidence were also found to increase through the use of readers theaters.
