Abstract
A response to intervention (RTI) methodology for both identification and remediation of students with learning disabilities (LD) and who are at-risk for reading difficulty is a highly efficable pedagogical approach that can be employed by classroom teachers. RTI integrates increasingly intensive intervention at three tiers of instruction. Student opportunity to learn and quality of instruction are two variables requiring additional research in order to be operationalized within the RTI construct. The classroom teacher, by using RTI, is better prepared to advocate for a student to be identified as LD and at-risk for reading failure, or not, as a result of the data gathered through this methodology. This approach reduces over-identification and facilitates a more efficient use of special needs instructional resources.
Wait to Fail: Learning Disabilities, Reading Failure, and Response to Intervention
A response to intervention (RTI) methodology for both identification and remediation of students with learning disabilities (LD) who are at-risk for reading difficulty or failure is a highly efficable pedagogical approach that can and should be employed by classroom teachers on a school wide basis. Further, this approach should be employed as an early identification and intervention strategy in order to remediate reading difficulty in a student with LD and offset the potentially devastating affects reading failure will have on a student with LD over the course of their lives (Coyne, Zipoli & Ruby, 2006, p.166).
Following, is an examination of the literature respecting students with LD at-risk for reading difficulty or failure, the efficacy and utility of a response to intervention approach to remediation of this risk, how this approach might be employed in the school setting, and suggestions respecting next steps in the research.
Background
LD can be defined as a disorder that affects the acquisition, retention, understanding, organization or use of verbal and/or non-verbal information (Learning Disabilities Association of Ontario, n.d.). One of the most prevalent types of academic difficulty facing students with LD is reading (Smith, Polloway, Patton & Dowdy, 2004, p.138; Lindsey & Kerlin, 1979, p.60).
Historically, IQ-achievement discrepancy assessments have been the most frequently used method for identifying a student as LD and at-risk for reading failure (Smith et al., 2004, p.142). That is, comparing IQ scores of individual students against expected performance exemplars, relative to normative peer group data, in order to determine if that student is LD and at-risk for reading failure. The weaknesses of this approach are twofold: the assessment occurs at one point in time and norm-referenced assessments have inherently low reliability (Smith et al., 2004, p.144).
Identifying students and targeting preventative intervention, based on a one time, universal screening result, leads to over-identification of students at risk for reading failure (Goodman & Webb, 2006, p.59). Further, this assessment has been typically administered within a “wait-to-fail” context. That is, assessments have tended to be undertaken at the end of third grade. By this point in time, students experiencing reading difficulty almost never become good readers (Coyne, Kame’enui & Simmons, 2001, p. 69; Vaughn & Roberts, 2007, p. 139). As well, a lack of reading competence and fluency at this point in time places the child at risk to ultimately drop out of school (Vaughn & Roberts, 2007, p.138).
Research indicates that difficulties with reading may impede the development of language, knowledge, and vocabulary skills. This phenomenon is referred to as the “Matthew Effect”. This is the notion that the rich get richer and the poor get poorer or, in this case, the wait-to-fail model contributes to increased severity of global academic difficulties for students in later grades (Dunn, 2007, p.32; Fuchs, Fuchs, Mathes, Lisey, Roberts, 2001, p.5; Lindsey & Kerlin, 1979, p.60), as reading ability becomes more critical in content-area instruction (Lindsey & Kerlin, 1979, p.61).
Emergent and long-term reading difficulty in most children are caused primarily by experiential and instructional deficits rather than biologically based cognitive deficits (Vellutino, Scanlon, Small & Fanuele, 2006, p.167). That is, most reading difficulty can be remediated through the provision of experiential and instructional interventions. IQ-achievement discrepancy assessments do not control for a student’s pre-school or educational history (Vellutino et al., 2006, p.157). This deficiency furthers the case for an alternative assessment and identification methodology.
With respect to early intervention, students identified as at-risk for reading difficulty in kindergarten, who received some form of intervention, generally performed better than those who did not on measures of emergent literacy skills. Further, these students were found to be no longer at-risk in first grade and beyond (Vellutino et al., 2006, p.168). Finally, students identified as at-risk for reading difficulty who were difficult to remediate (i.e., did not respond at the same level as their at-risk cohort) were found to have weaker cognitive profiles than either their at-risk cohort or the normally achieving cohort (Vellutino et al., 2006, p.168). This further suggests that, with respect to LD and at-risk for reading failure identification, students may need to be differentiated and targeted for intervention in different ways (Vaughn & Fuchs, 2003, p.138; Kauffman, Gerber & Semmel, 1988, p.6).
The Case for Response to Intervention
As a method for identifying students with LD at-risk for reading failure, RTI affords the potential for both early identification and intervention. As such, RTI represents an efficable alternative to IQ-achievement discrepancy assessments (Compton, Fuchs, Fuchs & Bryant, 2006, p.405). RTI integrates increasingly intensive intervention at (typically) three tiers of instruction. Each tier employs assessment to identify students who are not responding adequately and require intervention at the next, more intensive, tier (Fuchs & Fuchs, 2006, p.621).
At the primary/junior level, RTI typically begins as instruction in the regular classroom. Students who fail to respond to this universal core program of instruction move to the second tier of intervention. This second tier employs scientifically valid and reliable small-group tutoring instructional programming. Students who fail to respond to this more intensive instruction move to the third tier of intervention, typically individualized programming targeted at the unique needs of the student (Fuchs & Fuchs, 2006, p.621; Fuchs & Fuchs, 2007, p.16; Dunn, 2007, p.32; Vaughn & Fuchs, 2003, p.138).
The benefits of RTI include identification of students using an at-risk rather than deficit model, early identification of and intervention for students with LD, reduction of identification bias, and a strong focus on student outcomes (Vaughn & Fuchs, 2003, p.140). Further, at the tier-two stage of RTI, should the student fail to respond to intervention it can be assumed that the student possesses an intrinsic deficit or disability that prevents the child from benefiting from instruction (Davis, Lindo & Compton, 2007, p.32; Vaughn & Fuchs, 2003, p.143). This improves a school’s ability to accurately identify LD students and target scarce special needs (tier-three) resources more efficiently (Jenkins & O’Connor, 2001, p.4; Fuchs & Fuchs, 2007, p.15; Fuchs & Fuchs, 2006, p.622).
Suggestions for Future Research
There are two important determinants of student success: opportunity to learn and quality of instruction (Vaughn & Roberts, 2007, p.45). Evidence suggests that the locus of teacher efficacy (i.e, the extent to which a teacher believes he/she controls the events of the classroom and can produce desired learning outcomes) can be negatively influenced by a withdrawal versus full inclusion model for teaching students with special needs (Goodman & Webb, 2006, p.67). More study with respect to the influence of student withdrawal on both over identification and teacher efficacy would assist in buttressing the case for implementing RTI .
In order to further enhance the identification and intervention efficacy of the RTI model for students with LD at-risk for reading failure, further research is required to determine the effects of teacher quality and reading curriculum appropriateness, both of which have been shown to contribute to reading difficulty in primary grades (Compton et al., 2006, p.407). Further, the influence of the student’s home environment as a determinant of risk for reading failure should be considered. There is consensus that factors such as number of books in the home and familial history of LD have an influence on LD and reading failure risk (Davis et al., 2007, p.37; Dunn, 2007, p.34). These factors require further study in order to be operationalized within the RTI model.
Application in the Classroom Setting
Establishment of long term reading goals across grade levels and intermediate performance benchmarks employed school-wide with frequent student monitoring and reporting, coupled with coordinated and differentiated instructional interventions, will increase the efficacy of RTI implementation at the school level (Coyne et al., 2001, p.69). However, the RTI methodology offers several benefits to the individual classroom teacher. Following, is an examination of how RTI might be applied in the primary classroom, by the classroom teacher, and how the resultant data might be used.
A key issue the classroom teacher must grapple with is not only whether students are learning, but whether they are learning “enough” (Coyne et al., 2001, p.70). In order to determine whether students are learning enough, the classroom teacher can determine where students need to be with respect to reading skills at the critical point of third grade. From there, the classroom teacher can map expected progress back through each grade to kindergarten, thereby establishing milestones for each grade and point in time within a school semester (this is, of course, done in addition to other planning activities employed by schools and school boards).
At this point, RTI methodologies may be employed at the beginning of the year in order to establish baseline data for each student in the class. From there, the classroom teacher monitors each student’s response to instruction over the first few weeks of the semester. That is, performance against expectations is gauged in order to ensure each student is progressing adequately (tier-one). If and when the data demonstrates inadequate response to instruction, the classroom teacher must intervene (tier-two).
At tier-two, the teacher may have a group of students who have failed to respond to instruction. This group can be targeted, still within the classroom setting, for intervention. The classroom teacher would employ validated and reliable instructional programming for this group. This type of programming is typically available within the school or school board or can be purchased by the classroom teacher (this programming might include reading recovery or corrective reading products).
In terms of employing tier-two strategies, the research suggests that a cooperative learning (CL) model can be as efficable as individual instruction at this point in the intervention (McMaster & Fuchs, 2002, p.116) – and would fit within the pedagogical approach currently employed by most school boards in Ontario. Further, using a CL approach decreases the amount of time the classroom teacher needs to attend to the group and can be incorporated as a differentiated form of instruction within the regular classroom setting, thus increasing the chances of success and the ability of the classroom teacher to employ the approach.
The classroom teacher then monitors the group’s progress. Again, should some students fail to respond to instruction at tier-two, the classroom teacher must intervene. At this point, however, the teacher would collect and correlate the data generated at tier-one and tier-two for the student. This data then becomes the basis for the teacher to bring this student forward to the School Based Resource Team (SBRT). At this point, the student’s performance is reviewed and further tier-two recommendations may be made. Once all efforts at tier-two have been exhausted the SBRT may recommend referral to the Identification, Placement and Review Committee (IPRC).
At the IPRC, the classroom teacher would have all data from tier-one, tier-two, and the SBRT with which to make the case for an Individual Education Plan (IEP). In conjunction with IPRC members, and the student’s parents/guardians, recommendations for specific special needs programming and resources may be made, or not. The key here is that the classroom teacher has driven the process from early identification and intervention while collecting data throughout. It is, as a result, more likely that any identification of the student at this point, and any attendant special needs interventions, will be more efficable than might have been the case without the use of the RTI methodology.
