Two studies were conducted to examine the effects of Tier 2 and Tier 3 mathematics interventions on students with mathematics learning difficulties. In the first study, the work of Bryant et al. was replicated and expanded upon by documenting the sustained effects of a Tier 2 mathematics intervention on mathematics performance by second graders. In the second study, the Tier 2 intervention was intensified to a Tier 3 intervention through increases in two instructional features: group size and dosage. The results of the first study showed that the Tier 2 intervention improved mathematics performance for the majority of student participated in the study, and the effect of the intervention was sustained for the majority of students who responded to the Tier 2 intervention. The results of the second study showed that intensified Tier 3 intervention that involved one‐on‐one instruction and extended time for daily lessons may benefit students who have persistent difficulties with learning mathematics.  相似文献

Response-to-intervention (RTI) approaches to disability identification are meant to put an end to the so-called wait-to-fail requirement associated with IQ discrepancy. However, in an unfortunate irony, there is a group of children who wait to fail in RTI frameworks. That is, they must fail both general classroom instruction (Tier 1) and small-group intervention (Tier 2) before becoming eligible for the most intensive intervention (Tier 3). The purpose of this article was to determine how to predict accurately which at-risk children will be unresponsive to Tiers 1 and 2, thereby allowing unresponsive children to move directly from Tier 1 to Tier 3. As part of an efficacy study of a multitier RTI approach to prevention and identification of reading disabilities (RD), 129 first-grade children who were unresponsive to classroom reading instruction were randomly assigned to 14 weeks of small-group, Tier 2 intervention. Nonresponders to this instruction (n = 33) were identified using local norms on first-grade word identification fluency growth linked to a distal outcome of RD at the end of second grade. Logistic regression models were used to predict membership in responder and nonresponder groups. Predictors were entered as blocks of data from least to most difficult to obtain: universal screening data, Tier 1 response data, norm referenced tests, and Tier 2 response data. Tier 2 response data were not necessary to classify students as responders and nonresponders to Tier 2 instruction, suggesting that some children can be accurately identified as eligible for Tier 3 intervention using only Tier 1 data, thereby avoiding prolonged periods of failure to instruction.  相似文献

ABSTRACT

In Tanzania, many people are not aware of the concept of learning disabilities. Parents and teachers often do not realise that children who do poorly in school and do not have visible disabilities, could still have a disability that is causing their poor school performance. This paper presents the results of a research and service project to identify and support students with mild disabilities in an inclusive school in Tanzania during the three-year pilot process. An international NGO implemented a culturally-relevant, curriculum-based assessment for screening grade 1 students with potential delays or disabilities and provided Tier 2 interventions through small group lessons. In this three-year study, 413 students were screened, 108 students received Tier 2 services and six students received Tier 3 services. Students in Tier 2 received small group instruction in mathematics and literacy as a pull-out programme. Students in Tier 3 attended a special school for children with disabilities. Results showed that students who received Tier 2 intervention made statistically significant gains in their assessment scores after six and twelve months of services. This study demonstrated one successful assessment and intervention model in a typical Tanzanian school to support young children with disabilities to improve their academic outcomes.  相似文献

Abstract

?Multitiered systems of reading instruction and intervention, including response to intervention, are widely used in early reading by schools to provide more intense services to students who need them. Research using randomized controlled trials has compared innovative Tier 2 interventions to business-as-usual Tier 2 approaches and established a number of important components that compose effective Tier 2 interventions in early reading. The purpose of this study was to test the impact of a Tier 2 intervention with Tier 2 compared to Tier 1 instruction alone using regression discontinuity. A cut score was used to assign first-grade students at risk for reading difficulties to Tier 2 intervention plus Tier 1 instruction. Students who missed the cut score in the control group received Tier 1 instruction only. Students in the treatment group, just below the cut score, made greater gains on the SAT10 total score and the individual subtests than students just above the cut score. Outcomes were not significant on oral reading fluency.  相似文献

Within a multitiered system of support (MTSS), students who struggle to learn mathematics often receive core instruction and supplemental intervention in different settings, with different teachers and different sets of curriculum materials, all of which can result in poor alignment. This curriculum crosswalk describes how three sets of materials commonly used to provide core instruction and intervention differ with regard to mathematics practices and vocabulary. The results indicate that there is little overlap among all three programs for the majority (n = 6) of the mathematics practices, and very little overlap in mathematics vocabulary (ranging from 6.3 to 24 percent). We also provide a set of research-based instructional recommendations intended to help teachers address gaps and improve alignment of core instruction and intervention.  相似文献

In this review, we explore the extent to which researchers evaluating the efficacy of Tier 2 elementary reading interventions within the framework of Response to Intervention reported on fidelity of implementation and alignment of instruction between tiers. A literature search identified 22 empirical studies from which conclusions were drawn. Results suggest that fidelity of implementation is typically monitored at Tier 2 and that alignment between tiers of intervention is often apparent yet not explicitly stated. However, researchers frequently neglect to report on fidelity of intervention in Tier 1, potentially limiting claims that can be made about the efficacy of subsequent Tier 2 intervention. Limitations and implications for future research are discussed.  相似文献

This meta‐analysis synthesized 26 published single‐case design (SCD) studies on Tier 2 behavior interventions implemented within the educational framework of school‐wide positive behavioral interventions and supports. We used Tau‐U indices to determine the overall magnitudes of effect of the Tier 2 behavior interventions and the potential variables that moderate improved student behavioral outcomes. The 26 studies that were analyzed included a total of 243 student participants. The studies were evaluated to determine whether and to what extent they met What Works Clearinghouse (WWC) SCD standards. Of these, 10 studies were confirmed as meeting WWC SCD standards with or without reservations. Notable findings were that outcomes for students in kindergarten and secondary grade levels were limited, and insufficient screening methods were used to identify and select students needing Tier 2 interventions. The results indicate that the literature reports Tier 2 interventions with effect sizes ranging from 0.26 to 0.98. Average effect size for social skills instruction was found to be large, whereas Check‐in/Check‐out, group contingency, and intervention packages had medium effect sizes. Moderator analyses indicated different effect sizes across intervention types, outcomes, and implementers. The results are discussed in relation to implications for practice, limitations, and future research.  相似文献

To evaluate the effects of an intensive tertiary reading intervention, 27 students with severe reading difficulties and disabilities, 14 of whom had demonstrated an inadequate response to 1-2 tiers of prior reading instruction, received a 16-week intervention package involving decoding and fluency skills. The decoding intervention was provided for 2 hours per day for 8 weeks and was based on the Phono-Graphix program. The fluency intervention followed the decoding intervention and involved 1 hour of daily instruction for 8 weeks based on the Read Naturally program. The 16-week intervention resulted in significant improvement in reading decoding, fluency, and comprehension. Although individual responses to the intervention were variable, 12 of the 27 students showed a significant response to these interventions. Students who had participated in previous Tier 1 plus Tier 2 interventions but remained impaired had a stronger response to intervention in the current study than students who had previously participated only in Tier 1 intervention and students who had not received prior intervention outside of special education.  相似文献

Abstract

Considerable research evidence supports the provision of explicit instruction for students at risk for reading difficulties; however, one of the most widely implemented approaches to early reading instruction is Guided Reading (GR; Fountas & Pinnel, 1996), which deemphasizes explicit instruction and practice of reading skills in favor of extended time reading text. This study evaluated the two approaches in the context of supplemental intervention for at-risk readers at the end of Grade 1. Students (n = 218) were randomly assigned to receive GR intervention, explicit intervention (EX), or typical school instruction (TSI). Both intervention groups performed significantly better than TSI on untimed word identification. Significant effects favored EX over TSI on phonemic decoding and one measure of comprehension. Outcomes for the intervention groups did not differ significantly from each other; however, an analysis of the added value of providing each intervention relative to expected growth with typical instruction indicated that EX is more likely to substantially accelerate student progress in phonemic decoding, text reading fluency, and reading comprehension than GR. Implications for selection of Tier 2 interventions within a response-to-intervention format are discussed.  相似文献

Three levels of prevention and intervention in the area of mathematics are addressed: (a) primary prevention focusing on universal design, (b) secondary prevention focusing on adaptations, and (c) tertiary prevention focusing on intensive and explicit contextualization of skills‐based instruction. The purpose of this paper is to identify and discuss principles of prevention and intervention in the area of mathematics. First, we identify research‐based principles associated with primary prevention. Second, we turn our attention to secondary prevention, with a focus on prereferral intervention. We identify principles that serve to differentiate primary and secondary prevention and specify instructional variables that are promising for use within a secondary prevention mode. Finally, we discuss intervention. We identify principles of effective intervention, which include individually referenced decision making, instructional intensity, and deliberate contextualization of skills‐based instruction.  相似文献

ABSTRACT

This study examined the efficacy of a kindergarten mathematics intervention program, ROOTS, focused on developing whole-number understanding in the areas of counting and cardinality and operations and algebraic thinking for students at risk in mathematics. The study utilized a randomized block design with students within classrooms randomly assigned to treatment or control conditions. Measures of mathematics achievement were collected in the fall (pretest) and spring (posttest) in kindergarten and in the winter of first grade (delayed posttest). Significant differences between conditions favoring treatment students were found on four of six measures at posttest. Treatment students reduced the achievement gap with their not-at-risk peers. No effect was found on follow-up first-grade achievement scores. Implications for Tier 2 mathematics instruction in a Response to Intervention model are discussed.  相似文献

Tier 3 interventions are necessary for improving the reading performance of students who fail to respond adequately to Tier 1 general education instruction and Tier 2 supplemental reading intervention. In this pilot study, we identified 8 students in 3rd and 4th grade who had demonstrated slow response to Tier 2 reading interventions for three years. Students participated in a researcher‐developed Tier 3 intervention for 8 weeks that focused on skill development in word analysis, word identification, and reading rate. In the 6 months prior to Tier 3, students were making minimal growth in reading; however, during Tier 3, the 8 students demonstrated strong growth on measures of word identification and reading rate. Although results are promising for poor readers who are difficult to remediate, several aspects of the Tier 3 intervention need further testing.  相似文献

Tiers of intervention in kindergarten through third grade   总被引：1，自引：0，他引：1  
This study measured the effects of increasing levels of intervention in reading for a cohort of children in Grades K through 3 to determine whether the severity of reading disability (RD) could be significantly reduced in the catchment schools. Tier 1 consisted of professional development for teachers of reading. The focus of this study is on additional instruction that was provided as early as kindergarten for children whose achievement fell below average. Tier 2 intervention consisted of small-group reading instruction 3 times per week, and Tier 3 of daily instruction delivered individually or in groups of two. A comparison of the reading achievement of third-grade children who were at risk in kindergarten showed moderate to large differences favoring children in the tiered interventions in decoding, word identification, fluency, and reading comprehension.  相似文献

A fundamental assumption of multi-tiered systems of support is the bidirectional movement of students between tiers. In comparison to research on when to intensify instruction, less attention has been paid to the validity of decisions to exit students from supplemental supports. We used data from 554 third-grade students who met the criteria to be exited from a Tier 2 reading fluency intervention to answer two research questions. First, we used latent profile analysis to evaluate whether distinct profiles of student responding would emerge based upon initial skill level and intervention duration. Second, we evaluated whether the proportion of students who passed the end-of-year benchmark differed between profiles. Results favored a three-profile solution with a Below Average Start/Average Response; Average Start/Average Response; and an Above Average Start/Fast Response. The pooled mean proportion of students who did not achieve proficiency on the end-of-year benchmark assessment equaled 0.45, 0.33, and 0.13 across the three profiles, respectively. A series of χ2 tests indicated the between-profile differences were statistically significant (p < .05). The results of this study suggest that there may be distinct profiles amongst students who show positive response and exit Tier 2 reading fluency interventions.  相似文献

The purpose of this article is to describe the current research base and identify research needs related to response to intervention (RTI) frameworks in primary-grade reading. Research is reviewed on early reading instruction and intervention, the implementation of multitiered reading interventions, and the determination of intervention responsiveness. Areas identified as in need of research include (a) the conditions under which early reading interventions are most effective in RTI contexts, (b) multitiered interventions for students with limited English proficiency, (c) reading instruction for students who make limited progress in Tier 3 intensive interventions, (d) criteria for determining intervention responsiveness, and (e) the effects of fully implemented RTI frameworks. Although RTI research may be expensive and difficult to implement, it may contribute to improved reading outcomes for many students who are otherwise at risk of serious negative life consequences.  相似文献

Evidence-based practice is highly appreciated and demanded in the field of education, especially in relation to extra support provided for children struggling with learning. Currently, there is a lack of intervention studies in the area of mathematics. This study aimed to investigate the effects of a short mathematics intervention programme on second graders (Mage?=?8?years, 2?months) with low performance in mathematics, in a quasi-experimental, intervention-control setting. A group of low-performing second graders (LOWi, n?=?11) was taught twice a week for eight weeks on the mathematics topics of number word sequence skills, counting skills and conceptual place value knowledge. The intervention’s effectiveness was examined by comparing the mathematics performance of the LOWi group to those of two groups consisting of low performing (LOWc, n?=?13) and typically performing children (TYPc, n?=?64), who followed their business-as-usual mathematics instruction. The LOWi group made significant improvements in mathematics but did not show significantly better gains, compared to the LOWc and TYPc groups, immediately and three months after the intervention. We discuss the implications for educational practice and intervention research.  相似文献

Although research on Tier 2 interventions for early mathematics is accumulating, such efforts remain far behind those for reading, especially regarding specific features such as the ideal time to begin an intervention. The present study investigated the effectiveness of a Tier 2 intervention using a single subject multiple baseline, across-groups design with two cohorts of second graders. Because the two cohorts of students were given the intervention at different times during the second grade year, the study also documented whether the timing of the intervention affected acquisition and retention of second grade mathematics competencies. Finally, the study tracked student performance up to the first semester of the third grade year to document any sustained effects. The results show that the supplemental intervention was effective for both cohorts, but differences in performance indicate that the timing of the intervention may affect the degree of success. In addition, for some participants, the positive effects of the intervention were sustained into the third grade year.  相似文献

This study investigated whether mathematics education based on a multi-tiered response to intervention (RTI) model can support students' arithmetic competence in primary schools in Sweden. The intent was to identify and support students at risk of failure. In this study, 113 students participated in the intervention, and 30 students participated in the control group. Both groups were followed from Grade 1 to the end of Grade 2 and compared. During the first semester in Grade 1, all students were taught basic addition and subtraction with explicit instructions in Tier 1. Those who did not respond to Tier 1 after one semester were provided support within Tier 2 during the second semester. The same was repeated in grade 2 and the students that did not respond to Tier 2 were supported within Tier 3. At the end of Grade 2, students in the intervention group performed significantly higher on the basic arithmetic competence in the number range 1–9 than the control group. No significant difference was found in a test measuring basic arithmetic competence in the number range 10–19. This study shows that using multi-tiered RTI might be sufficient to identify and support students at risk in early arithmetic competence.  相似文献

Research Findings: In each of 16 public school classrooms serving multiethnic low-income neighborhoods, 2 first graders were assigned to be taught patterning, 2 to be taught reading, 2 to be taught mathematics, and 2 to be taught social studies for 15-min sessions 3 days per week for 6 months. Assignment within each classroom was randomized. The children's mean age was 6 years, 5.19 months. Patterning instruction included instruction on symmetrical patterns, patterns with increasing numbers of elements, and patterns involving the rotation of an object through 6 or 8 positions. In May, the 120 children still available were tested on patterns, reading, and mathematics. Patterning instruction had large, fully mediated effects on both reading and mathematics. There were no significant differences on some individual scales, but on others children who received patterning instruction scored best, often by grade equivalents of 4 to 8 months. Extant explanations of the efficacy of patterning instruction are reviewed, and the potential importance and limitations of its role in early education are discussed. Practice or Policy: Patterning instruction should be extended to more complex patterns than the alternations currently used in elementary schools in order to produce important improvements in both reading and mathematics.  相似文献

Some intensive quantities, such as slope, velocity, or likelihood, are perceptually privileged in the sense that they are experienced as holistic, irreducible sensations. However, the formal expression of these quantities uses a/b analytic metrics; for example, the slope of a line is the quotient of its rise and run. Thus, whereas students' sensation of an intensive quantity could serve as a powerful resource for grounding its formal expression, accepting the mathematical form requires students to align the sensation with a new way of reasoning about the phenomenon. I offer a case analysis of a middle school student who successfully came to understand the intensive quantity of likelihood. The analysis highlights a form of reasoning called abduction and suggests that sociocognitive processes can guide and mediate students' abductive reasoning. Interpreting the child's and tutor's multimodal action through the lens of abductive inference, I demonstrate the emergence of a proportional concept as guided mediated objectification of tacit perception. This “gestalt first” process is contrasted with traditional “elements first” approaches to building proportional concepts, and I speculate on epistemic and cognitive implications of this contrast for the design and instruction of these important concepts. In particular, my approach highlights an important source of epistemic difficulty for students as they learn intensive quantities: the difficulty in shifting from intuitive perceptual conviction to mediated disciplinary analysis. My proposed conceptualization of learning can serve as an effective synthesis of traditional and reform-based mathematics instruction.  相似文献
