Multi-tiered systems of support (MTSS) provide instruction and intervention to all students in schools. However, when many students within a setting demonstrate reading difficulties, there is likely a tier 1 problem which makes it infeasible to implement tier 2 or tier 3 interventions with large numbers of students due to limited resources. The…

Students with dyslexia demonstrate reading difficulty in early literacy skills (e.g., phonemic awareness, word recognition, decoding), and administering screeners is a necessary step to implement effective intervention. There are several commonly used reading screeners, but the decision accuracy and predictive value between them varies. In the…

A skill-by-treatment interaction (STI) isolates skill deficits and manipulates conditions to match them to student needs. Based on the learning hierarchy, preintervention scores can help predict which intervention will be most successful for an individual student. This study compared the efficacy of a modeling and practice-based decoding…

The purpose of this study was to examine: (1) the effect of a reading intervention based on reading need compared to a mismatched behavior intervention; and (2) the effect of an academic behavior intervention based on behavior need in comparison to a mismatched reading intervention. Six students took part in the multiple baseline study. Half of…

The purpose of the current study was to determine the extent to which practicing keywords increased word recognition, reading fluency and comprehension for students with intellectual disability (ID). The dependent measures included word recognition (i.e., the percentage of previously unknown keywords read correctly in the given text), reading…

This study examined the classification accuracy for subskill mastery measures administered in mathematics for students in kindergarten and Grades 1, 3, 5, and 7 at fall (n = 564) and winter (n = 602) screening. In addition, response to classwide math intervention was examined as another layer of screening for students in kindergarten and Grades 1,…

The current study determined growth patterns during an 8-week writing intervention and then examined the association between growth pattern and students' initial skills as determined by instructional-level data. One hundred forty-seven first-grade students struggling with early literacy skills received a writing intervention at one of two tiers of…

Teaching children too many words during a lesson reduces retention. The amount of new information a student can successfully rehearse and recall later is called acquisition rate (AR), which has been reliably measured with students in first, third, and fifth grades. The purpose of this study was to examine the reliability of assessing AR for sight…

Incremental rehearsal (IR) is a flashcard technique that has produced strong effects for a variety of outcomes including word recognition. We utilized theory-based modifications to IR to enhance maintenance and generalization of sight words. We utilized a within-subjects design in which 41 participants in 2nd and 3rd grade were taught seven…

The amount of information that students successfully learn and later recall from each intervention session is limited and is called the acquisition rate (AR). Research has consistently supported the effects of modifying intervention set sizes with AR data, but research with AR is in its infancy. The current study compared the relationship between…

Measures of Academic Progress (MAP) Skills is a web-based assessment system published by Northwest Evaluation Association (NWEA). The test publishers purport that MAP Skills provides information about essential K-8 building blocks in Language Usage, Mathematics, Reading Comprehension, and Vocabulary to quickly assess student progress toward…

This study compared the reading growth of students with and without learning disabilities, and students with and without reading deficits in response to tier 2 reading interventions within a response-to-intervention framework. Participants were 499 second- and third-grade students in six urban schools. Students who scored at or below the 10th…

Incremental rehearsal (IR) has consistently led to effective retention of newly learned material, including math facts. The number of new items taught during one intervention session, called the intervention set, could be used to individualize the intervention. The appropriate amount of information that a student can rehearse and later recall…

The purpose of this study was to examine the effects of Incremental Rehearsal (IR) and traditional drill (TD) on retention of multiplication facts with 29 students in third and fourth grades with low mathematical skills. Results indicated that IR led to significantly more facts being retained, and was essentially equal to TD for efficiency as…

Incremental rehearsal (IR) is a highly effective intervention that uses high repetition and a high ratio of known to unknown items with linearly spaced known items between the new items. It has been hypothesized that narrowly spaced practice would result in quick learning, whereas items that are widely spaced would result in longer-term retention.…
