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…

Few previous studies have directly linked the contribution of phonological awareness (PA) and rapid automatized naming (RAN) to the development of phonological processing and orthographic processing in reading. These studies are predominantly cross-sectional and focus on reading development predictors, with relatively little emphasis on spelling…

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…

Sight word learning occurs in most early elementary classrooms. Some kindergarten students face the prospect of learning up to 100 sight words, and many teachers feel pressure to ensure that students know lists of words by the year's end. The authors offer five assertions about sight word learning to direct teachers and administrators toward the…

The author reviews theory and research by Ehri and her colleagues to document how a scientific approach has been applied over the years to conduct controlled studies whose findings reveal how beginners learn to read words in and out of text. Words may be read by decoding letters into blended sounds or by predicting words from context, but the way…

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…

Learning irregular words involves mental marking of irregular letters in the spelling, a process not fully understood. In a within-subjects experiment, we manipulated the type of scaffolding given to beginning readers to evoke mental marking. We pretested to sort 103 kindergarten and first-grade participants into sequential decoders, who decode…

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…

In a test-driven educational environment, teachers see a great need for more engaging resources that produce the literacy results needed for students to thrive academically. In 2015, The National Assessment of Educational Progress reported that only 36% of fourth graders scored at or above the Proficient level of reading. This statistic was…
