Refining the experimental analysis of academic skills deficits: Part I. An investigation of variables that affect generalized oral reading performance

Experimental analyses for improving reading fluency deficits have rarely targeted generalized increases in academic responding. As a consequence, the variables that may help students to generalize newly learned forms of academic responding like reading are not well understood. Furthermore, experimental analyses of reading fluency interventions have not systematically examined difficulty level as a variable that may affect instructional outcomes. The experiment reported in this paper expands (a) the measurement of the dependent variables to include generalized increases across tasks (reading passages) and (b) the combination of independent variables used to produce measurable generalized increases. The results demonstrate the importance of combining reward and instructional variables (including difficulty level) to produce generalized increases and how those variables can be meaningfully investigated prior to making treatment recommendations.     

Improving reading outcomes for children with learning disabilities: using brief experimental analysis to develop parent-tutoring interventions

The present study assessed the effects of summer parent tutoring on 3 children with learning disabilities using empirically derived reading interventions. Brief experimental analyses were used to identify customized reading fluency interventions. Parents were trained to use the intervention strategies with their children. Parents implemented the procedures during parent-tutoring sessions at home and results were measured continuously in high-word-overlap and low-word-overlap passages to determine whether generalization occurred. Parent and child satisfaction with the procedures was assessed. Results demonstrated generalized increases in reading fluency in both high-word-overlap and low-word-overlap passages as a function of parent tutoring. Also, acceptability ratings by children and their parents indicated that they viewed the interventions as acceptable and effective. Results are discussed in terms of structuring reading fluency interventions that promote generalization and maintenance of treatment effects.     

Improving oral reading fluency by influencing students' choice of instructional procedures: an experimental analysis with two students with behavioral disorders

Choice as an antecedent intervention has been shown to improve student behavior in a variety of ways. This investigation examined whether students could be influenced to choose whether and how to be instructed while directly measuring effects on academic performance. Using a multiple‐probe design, the reading fluency of two middle school students with Behavioral Disorders was measured repeatedly across passages. Students could earn a tangible reward for meeting a pre‐determined performance criterion in passage reading. Prior to reading the criterion passage, each student was told that he or she could choose to be instructed or not be instructed in a similar passage with high content overlap. Both students consistently chose to be instructed (as well as how they would be instructed) and stable increases in oral reading fluency were obtained. Results are discussed in terms of how motivational variables can be used to influence students' choice of instructional procedures in ways that increase their opportunities to respond and measured learning.

Promoting parent use of empirically supported reading interventions: two experimental investigations of child outcomes

Two experimental investigations of the effects of parent delivered reading interventions were conducted. Tutoring packages consisting of empirically supported intervention components were delivered by parents for at least several weeks after initial parent training. Both experiments used single‐case experimental designs and measured participants' oral reading fluency in passages. Experiment 1 used a multiple‐probe design across tasks (passages) to evaluate tutoring effects for two students with learning disabilities. Results indicate that both students increased their reading fluency and maintained those increases over time. Experiment 2 used a brief experimental analysis that included both experimenter and parent delivered instructional trials to validate the treatment package. Next, the treatment package was evaluated using an alternating treatments design. Results were uniformly positive. An interesting but not surprising correlation was also found between treatment integrity and student outcomes. Results are discussed in terms of the framework and skills that behavior analysts have for working with parents and schools to improve their children's academic responding.

Teaching Phoneme Segmenting and Blending as Critical Early Literacy Skills: An Experimental Analysis of Minimal Textual Repertoires

The purpose of the current study was to examine blending and segmenting of phonemes as an instance of small, textual response classes that students learn to combine to produce whole word reading. Using an A/B/A/B design, a phoneme segmenting and blending condition that included differential reinforcement for response classes at the level of phonemes was compared to a control condition which was equated for differential reinforcement of reading words and opportunities to respond. The critical difference between conditions was the size of the responses that were brought under stimulus control (phonemes versus whole words). Findings clearly supported the superiority of the phoneme blending treatment condition over the control condition in producing generalized increases in word reading. The results are discussed in terms of the behavioral mechanisms that govern early literacy behaviors and the essential role that targeting measured increases in academic responses plays in furthering our understanding of how to improve the analysis and instruction of students who need to learn these important skills.     

Use of Brief Instructional Trials to Identify Small Group Reading Strategies: A Two Experiment Study

The Instructional Hierarchy (IH) has proven useful for understanding the functional properties of empirically valid instructional strategies. Investigators have relied heavily on the IH as a heuristic in conceptualizing instructional components used in brief experimental analyses. To date, only one investigation has applied brief experimental analysis results to small group reading interventions. The purpose of this paper is to describe two studies which used single session instructional trials to identify interventions that were subsequently applied to small group reading instruction. In both studies, individualized instructional trials that probed for skill and performance deficits were carried out and results suggested that all students benefited from the instructional intervention. Next, the intervention was implemented in a small group format. In Experiment 2, however, validation of the instructional package was carried out by the classroom teacher who delivered the instructional package to the small group. In both cases, extended experimental analyses suggested that the intervention was effective at improving all participants’ generalized reading fluency. Results of both studies are discussed in terms of how future studies can refine procedures for validating instructional and motivational components before classroom applications.     

An Experimental Analysis of the Effects of Reading Interventions in a Small Group Reading Instruction Context

The current study examined the effects of several combinations of instructional and motivational interventions on oral reading fluency in the context of small group reading instruction. A treatment package consisting of acquisition, fluency, and motivational components was examined and then dismantled. Results were evaluated individually for each participant using a multiple-probe design in order to identify the most effective, yet efficient reading intervention package for each member of the group. The results indicated that, although all potential combinations of the package were effective, the experimental analysis was able to identify an effective yet more efficient package that produced substantial increases in performance across all students. Results are discussed in terms of effective instructional components in small group instruction and how to adapt methods for the experimental analysis of behavior to make decisions about the effectiveness of small group instruction in reading.This study is based on a dissertation submitted by the first author in partial fulfillment of requirements for the doctoral degree.     

Refining the experimental analysis of academic skills deficits: part II. Use of brief experimental analysis to evaluate reading fluency treatments

The technology of brief experimental analysis is just beginning to be used for identification of effective treatments for individual students who experience difficulty with oral reading fluency. In this study, the effect of a reading fluency treatment package was examined on easy and hard passages, and generalization was assessed on passages with high content overlap. The results suggest that the treatment package increased reading fluency for all 3 students. Effects were moderated by difficulty level for all 3 students. Results are discussed in terms of future refinements to the procedures, validation of the methods, and potential applications in clinical and school settings.
