From letter names to word reading: The nascent role of sublexical fluency

Information processing theory suggests that sublexical fluency skills are important to word reading development, but there are few supportive data. This study investigated if sublexical fluency (letter name fluency, letter sound fluency, and phoneme segmentation fluency) contributed to the development of word reading and spelling in 92 kindergarten children. The pattern of findings suggests that, as early as kindergarten, sublexical fluency skills explain a small, but significant, amount of unique variance in literacy outcomes when also considering the influence of accuracy in these skills. Also, growth in sublexical fluency skills is related to both word reading and spelling proficiency at the end of kindergarten. We suggest that knowledge of early literacy skill development may be enhanced by attention to sublexical fluency and that these skills, specifically letter sound fluency, may provide the mechanism that supports early word reading and spelling.     

Precision teaching through Irish: effects on isolated sight word reading fluency and contextualised reading fluency

The current study examines the impact of a three-week precision teaching (PT) intervention programme through the Irish language on a group of primary school pupils’ Irish reading fluency. The study employed a mixed factorial experimental design. Thirty-six Irish primary school pupils who were learning Irish as a second language were recruited for this study. Participants were divided evenly into two groups: experimental and control (N?=?18). Participants completed tests of isolated sight word reading fluency and contextualised reading fluency before and after the PT intervention programme. The experimental group was exposed to the PT programme, which focused on isolated Irish vocabulary, while the control group experienced typical teaching of Irish. The results of a one-way multivariate analysis of variance and a series of dependent-samples t-tests revealed that in contrast to the control group, the experimental group exhibited a significant increase in both isolated sight word reading fluency and contextualised reading fluency following the intervention. This study emphasises the potential value of utilising PT to aid second language learning, not only for increasing isolated sight word reading fluency, but also for enhancing contextualised reading fluency.     

Math fluency is etiologically distinct from untimed math performance, decoding fluency, and untimed reading performance: evidence from a twin study

The authors examined whether math fluency was independent from untimed math and from reading using 314 pairs of school-aged twins drawn from the Western Reserve Reading and Math Projects. Twins were assessed through a 90-min home visit at approximately age 10 and were reassessed in their homes approximately 1 year later. Results suggested that the shared environment and genetics influenced the covariance among math fluency, untimed math measures, and reading measures. However, roughly two thirds of the variance in math fluency was independent from untimed math measures and reading, including reading fluency. The majority of this independent variance was the result of genetic factors that were longitudinally stable across two measurement occasions. These results suggest that math fluency, although related to other math measures, may also be a genetically distinct dimension of mathematics performance.

Accuracy feedback improves word learning from context: evidence from a meaning-generation task

The present study asked whether accuracy feedback on a meaning generation task would lead to improved contextual word learning (CWL). Active generation can facilitate learning by increasing task engagement and memory retrieval, which strengthens new word representations. However, forced generation results in increased errors, which can be detrimental for learning if they are not corrected. The goal of this study was to determine whether immediate feedback on response accuracy would ameliorate this risk. The study was conducted using an intelligent tutoring system, which presents target words in multiple contexts and prompts users to generate a target word meaning after each context. One group of participants (feedback group) received immediate feedback based on Markov Estimation of Semantic Association (MESA), which estimates the distance between the learner response and the target word meaning. The control group did not receive feedback. Results from conventional (pre/post-test) measures showed greater gains in accuracy and confidence for the feedback group. Moreover, when contextual support was decreased mid-way through the training (from trial 3 to trial 4), MESA measures showed a corresponding drop in accuracy, but only for the No-Feedback group. These findings suggest that accuracy feedback can improve outcomes in CWL, particularly when there is an increased risk of errors. This strengthens the case for meaning generation as a tool to build high-quality lexical representations.

New evidence on the development of the word big

Previous studies of children's understanding of big suggest a curvilinear trend. 3-year-olds, like adults, interpret big as referring to area, while 5-year-olds take big to mean tall. The results of 6 experiments indicate that the curvilinear trend is not obtained in all stimulus contexts. When objects vary extremely, younger and older children take big to mean tall. The object to which big is applied also influences whether height, length, or area is attended to. Moreover, in a production task, adults rarely used the work big to describe the stimuli with which children's understanding of big is typically tested. Taken together, the results suggest that the meaning and use of big is complex and that big may not at any age refer simply to the larger object. It is proposed that the meaning of big is a dynamic system driven by a multiple of perceptual, conceptual, and semantic influences.     

The role of letter knowledge acquisition ability on children's decoding and word identification: Evidence from an artificial orthography

Background

Letter knowledge is crucial in the first stages of reading development. It supports learning letter-sound mappings and the identification of the letters that make up words. Previous studies have investigated the longitudinal impact of early letter knowledge on children's further word reading abilities. This study employed an artificial orthography learning paradigm to explore whether the rate of letter learning modulates children's reading and word identification skills.

Methods

In an initial training phase, 8-year-old Spanish children (N = 30) learned nine artificial letters and their corresponding sounds (two vowels and six consonants). The letter learning rate was set according to the number of attempts needed to name at least seven letters (i.e., 80% correct). These ranged from 1 to 4. In a second training phase, children visualized words made up of the trained letters while listening to their pronunciations. Some words included a context-dependent syllable (i.e., leading to grapheme-to-phoneme inconsistency), and others had an inconsistent syllable (i.e., phoneme-to-grapheme inconsistency). The post-test consisted of a reading aloud task and an orthographic-choice task in which the target word was presented with a distractor equal to the target except for the substitution of a letter.

Results

Children showed a high accuracy rate in the post-test tasks, regardless of whether words contained context-dependent or inconsistent syllables. Critically, the letter learning rate predicted both reading aloud and identification accuracy of words in the artificial orthography.

Conclusions

We provide evidence for the vital role of letter knowledge acquisition ability in children's decoding and word identification skills. Training children on this ability facilitates serial letter-sound mapping and word identification skills. Artificial orthography paradigms are optimal for exploring children's potential to achieve specific literacy skills.

     

Visual constraints in written word recognition: evidence from the optimal viewing‐position effect

In this paper we review the literature on visual constraints in written word processing. We notice that not all letters are equally visible to the reader. The letter that is most visible is the letter that is fixated. The visibility of the other letters depends on the distance between the letters and the fixation location, whether the letters are outer or inner letters of the word, and whether the letters lie to the left or to the right of the fixation location. Because of these three factors, word recognition depends on the viewing position. In languages read from left to right, the optimal viewing position is situated between the beginning and the middle of the word. This optimal viewing position is the result of an interplay of four variables: the distance between the viewing position and the farthest letter, the fact that the word beginning is usually more informative than the word end, the fact that during reading words have been recognised a lot of times after fixation on this letter position and the fact that stimuli in the right visual field have direct access to the left cerebral hemisphere. For languages read from right to left, the first three variables pull the optimal viewing position towards the right side of the word (which is the word beginning), but the fourth variable counteracts these forces to some extent. Therefore, the asymmetry of the optimum viewing‐position curve is less clear in Hebrew and Arabic than in French and Dutch.     

Listening previewing in reading to read: Relative effects on oral reading fluency

An intervention designed to increase oral reading fluency (Reading to Read; RTR) as well as the additional component of listening previewing (PRV) was evaluated in an alternating treatments design with 3 African-American male elementary students (9, 10, and 12 years of age; 2 fourth grade and 1 third grade) who were reading 2 to 3 years below their current grade placement. Considering the relatively brief amount of time spent during intervention (4 to 9 weeks; 2 to 3 30-minute sessions per week), results evidenced substantial increases for all 3 students on correct words per minute and percent comprehension accuracy, and substantial decreases in mean number of errors. The PRV condition yielded higher correct words per minute rates and lower error rates for 2 of the students, whereas the third student's performance was superior with the regular RTR intervention without PRV. The efficacy of PRV within RTR is discussed with regard to factors related to students' attentional problems.     

The impact of digital skills on educational outcomes: evidence from performance tests

Digital skills are increasingly important for labour market outcomes and social participation. Do they also matter for academic performance? This paper investigates the effects of digital literacy on educational outcomes by merging data from the Italian National Assessment in secondary schools with an original data-set on performance tests of Internet skills for tenth-grade students. Our identification strategy relies on a rich set of individual, family, school and classroom control variables that are not commonly available in previous studies. The findings indicate that, overall, Internet skills have a positive impact on academic achievement. This effect is stronger for students with low academic performance or low family background. It is also stronger for students in technical or vocational schools.

Strong tests of developmental ordering hypotheses: integrating evidence from the second moment

Developmental ordering is a fundamental prediction in developmental science. However, tests of ordering hypotheses are not generally available for continuously developing variables. One promising test of developmental ordering, the shape of the relationship between 2 variables, requires that changes in each underlying variable are captured equally well across the developmental span (measures are linearly related to the variables). If either measure is more sensitive to earlier or later developmental changes in the underlying variable, the shape of the relationship changes radically. The article demonstrates that the viable alternative hypotheses for an observed developmental relationship require specific types of nonlinearity in measurement and, therefore, have testable predictions for the residuals (the second moment). Ordering as evidence in developmental science is discussed.     

Schooling effects on undergraduate performance: evidence from the University of Barcelona

This study analyzes the effects of several factors related to high school, such as the kind of school (public or private), the type of education (general or vocational), school location and peers on undergraduate performance from students of the University of Barcelona (Spain). Particular attention is given to the functional form and to the collection of “unobservables”. Empirical results show that variables related to high school, such as having attended in a private religious school or peer effects of their school contemporaries, are determinant in university final grades. In addition, students’ ability, some household’s characteristics and the 1990 Education Act are also important.     

Class size effects on mathematics achievement in Cyprus: evidence from TIMSS

Class size reduction has been viewed as one school mechanism that can improve student achievement. Nonetheless, the literature has reported mixed findings about class size effects. We used 4th- and 8th-grade data from TIMSS 2003 and 2007 to examine the association between class size and mathematics achievement in public schools in Cyprus. We employ instrumental variables methods, and take advantage of a regression discontinuity design to examine causal effects of class size on mathematics achievement. The results indicate a non-significant relationship between class size and mathematics achievement in 8th grades. However, there is evidence of positive class size effects in 4th grade. The gender gap is significant and favoured males in 4th grade and females in 8th grade. SES indexes such as parental education and items in the home are positively and significantly related to mathematics achievement. Teacher and school variables are not significantly related with mathematics achievement.     

Understanding the relations between RAN letter subtest components and word reading in first-grade students

First-grade students (N = 221) were individually tested on a battery of cognitive and achievement measures of verbal fluency, visual attention, phonological awareness, orthographic recognition, rapid automatized naming (RAN) of letters and objects, and reading. All tests were subjected to postacquisition scoring, and all RAN measures were segregated into measures of articulation time, pause time, and consistency of the pause time. Structural equation modeling demonstrated that word reading was directly and significantly predicted by RAN letter naming and general RAN cognitive processing time of objects. Moreover, RAN letter reading constructs were significantly and directly predicted by the latent variables of phonological awareness, orthographic recognition, and general RAN object articulation and cognitive processing times. RAN letter naming constructs were also significantly and indirectly predicted by visual attention. The reading model was found to be consistent with a total mediation of the relation of phonological awareness and reading through RAN letter naming and supported the validity of the RAN letter naming subtest as a basic letter reading test. These findings supported the double-deficit hypothesis for letter reading. We suggest that phonological memory is a basic factor underlying general RAN cognitive processing time of objects and domain-specific information associated with phonemes and their graphic representations.
