Instructors assess the acquisition of new skills by delivering blocks of trials containing multiple operants. Mastery is evaluated as percentage correct across all operants in the block. The purpose of the current study was to investigate this traditional mastery criterion arrangement compared to an analysis of mastery at the level of individual…

This study measured the effectiveness of sight word practice using flashcards and the growth results were compared based on presentation formats when administered to a group of second grade students. The data were later disaggregated to compare the success rates of each platform among three different subgroups within the test population, based on…

Discrimination of reversible mirrored letters (e.g., d and b) poses a challenge when learning to read as it requires overcoming "mirror invariance," an evolutionary-old perceptual tendency of processing mirror images as equivalent. The present study investigated "when," in reading development, mirror-image discrimination…

Automation of frequently used words is a key component in the development of reading fluency. However, acquiring fast word recognition skills is a serious challenge for many children in their early years of formal education. Lagging word recognition leads to general reading problems, as fluency is a vital prerequisite for text comprehension.…

Assessing a student's acquisition rates (ARs) is a reliable way to determine how many new words should be taught in one lesson without reducing retention. Exceeding a student's AR can result in frustration and problem behaviors. The purpose of this study was to examine the effect of AR on the off-task behavior of kindergarten students while…

The number of students with reading difficulties is increasing and reading motivation is decreasing. Although serious reading problems can still persist during secondary education, most reading instruction happens in primary schools. In particular, students with learning disabilities and externalising behavioural problems are confronted with…

Recently, there has been growing concern about how to most effectively support the literacy development of beginning and struggling readers with regard to helping them learn to effortlessly identify the huge number of words that proficient readers ultimately learn to read with automaticity. Some, noting the critical importance of phonics…

Working with a post-secondary student with intellectual disability, an adapted alternating treatments design was used to compare sight-word acquisition across three computer-delivered learning trial interventions: one with fixed 5-s response intervals, another with fixed 1-s response intervals, and a third with self-determined intervals. Visual…

This mixed methods cross-sectional survey study framed in amalgamation theory (Ehri, 2020) and the Simple View of Reading (Gough & Tunmer, 1986) explored the ways in which k-2 general classroom teachers define, understand, and teach sight word development through an orthographic mapping lens. The study utilized a convergent parallel design to…

The aim of this single-case study was to evaluate the effects of a Direct Instruction flashcard system on the sight word identification of a tenth grader with a learning disability. To appraise the benefits of the intervention, a changing criterion single-subject design was applied. Findings indicated that the student profited greatly from the…

We modeled word reading growth in typically developing (n = 118) and children with dyslexia (n = 20), Grades 2-5, across multiple exposures to 30 words. We explored the facilitative versus inhibitory effects of exposures to differential mixes of words that support high- versus low-frequency vowel pronunciations. One training corpus contained a…

This study examined the effects of a reading racetrack game on acquisition, maintenance, and generalization of sight words for four kindergarten students who are deaf. The game consisted of placing sight words around a racetrack board and prompting the participant to read the words. A multiple probe design across word sets demonstrated a…

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…

For the purpose of this research, a concurrent multiple baseline design was used to measure the effects of a Constant Time Delay (CTD) intervention. CTD was implemented as an intervention to support four transition students' abilities to recognize functional sight words. The sessions were held during a summer transition program on a large…

The role of verbal working memory (VWM) in early language and literacy development among typical and atypical monolingual children exposed to different orthographies is well established. Less is known how English Language Learners (ELLs) allocate their VWM resources in early stages of literacy acquisition in English (L2). This study examined the…
