Exploring the use of network meta-analysis in education: examining the correlation between ORF and text complexity measures

Abstract

Calls for empirical investigations of the Common Core standards (CCSSs) for English Language Arts have been widespread, particularly in the area of text complexity in the primary grades (e.g., Hiebert & Mesmer Educational Research, 42(1), 44–51, 2013). The CCSSs mention that qualitative methods (such as Fountas and Pinnell) and quantitative methods (such as Lexiles) can be used to gauge text complexity (CCSS Initiative, 2010). However, researchers have questioned the validity of these tools for several decades (e.g., Hiebert & Pearson, 2010). In an effort to establish criterion validity of these tools, individual studies have compared how well they correlate with actual student reading performance measures, most commonly reading comprehension and/or oral-reading fluency (ORF). ORF is a key aspect of reading success and as such is often used for progress monitoring purposes. However, to date, studies have not been able to evaluate different text complexity tools and relation to reading outcomes across studies. This is challenging because the pair-wise meta-analytic model is not able to synthesize several independent variables that differ both within and across studies. Therefore, it is unable to answer pressing research questions in education, such as, which text complexity tool is most correlated with student ORF (and, thus, a good measure of text difficulty)? This question is timely given that the Common Core State Standards explicitly mention various text complexity tools; yet, the validity of such tools has been repeatedly questioned by researchers. This article provides preliminary evidence to answer that question using an approach borrowed from the field of medicine—Network Meta-Analysis (NMA; Lumley Statistics in Medicine, 21, 2313–2324, 2002). A systematic search yielded 5 studies using 19 different text complexity tools with ORF as the reading outcome measured. Both a frequentist and Bayesian NMA were conducted to pool the correlations of a given text complexity tool with students’ ORF. While the results differed slightly across the two approaches, there is preliminary evidence in support of the hypothesis that text complexity tools which incorporate more fine-grained sub-lexical variables were more strongly correlated with student outcomes. While the results of this example cannot be generalized due to the low sample size, this article shows how NMA is a promising new analytic tool for synthesizing educational research.

E-book reading hinders aspects of long-text comprehension for adults with dyslexia

Abstract

Developmental dyslexia is a long-lasting reading deficit that persists into adulthood. In spite of many difficulties, some adults with dyslexia reach levels of reading comprehension similar to those of unimpaired readers and successfully study at university. While digital technologies offer many potential tools to facilitate reading, there are differences between printed books and e-books, particularly regarding the interaction between the reader and the text (paratextual cues). This study used long-text reading to investigate (1) different aspects of reading comprehension skills (literal and inferential processes, location of events within a story, and reconstruction of the plot) among university students with dyslexia and (2) the impact of e-book reading on reading comprehension in this population. Thirty adults with dyslexia and 30 matched skilled readers read the same text presented from a printed book and an e-book (Amazon Kindle). Questions were open-ended and both questions and answers used oral format. Results showed that with the printed book, dyslexic adults performed similarly to skilled readers in both literal and inferential reading comprehension tasks. Moreover, they performed at the same level or higher than skilled readers in tasks assessing spatiotemporal aspects of reading (localization of events and plot reconstruction). Conversely, with the e-book reader, the dyslexic adults were outperformed by skilled readers both in literal and spatiotemporal comprehension tasks. These results suggest that reading from an e-book hinders some aspects of reading comprehension for adults with dyslexia. However, when reading a printed book without time pressure, university students with dyslexia performed as well as, or better than, non-impaired readers on some measures of reading comprehension. Therefore, digital reading devices might not always be advantageous to them.

Development of orthographic representations in Spanish children with dyslexia: the influence of previous semantic and phonological knowledge

Abstract

In transparent orthographic systems, the main characteristic of developmental dyslexia is poor reading fluency. Several studies have reported that children with dyslexia have difficulties forming orthographic representations of words, which hampers good reading fluency. This study aimed at evaluating whether the semantic–phonological training prior to word reading could facilitate the formation of orthographic representations and leading an improvement in reading fluency. Twenty-four native Spanish-speaking children with developmental dyslexia carried out two different reading tasks. In one of them, participants previously received semantic and phonological information about stimuli whereas in the other task no previous information was provided. Eight different unfamiliar words (four short and four long) were used in each reading task and the reduction of the length effect across reading blocks was taken as a formation index of new orthographic representations. Results showed low accuracy, slow speed reading, and difficulties in developing orthographic representations despite of repeated reading, probably due to the instability in decoding processes. However, the previous phonological and semantic training had a facilitator effect in the formation of orthographic representations, as indicated by the decrease in the length effect.

Are predictors of reading impairment in isolated cleft similar to those in idiopathic dyslexia?

Abstract

Children with isolated cleft of the lip and/or palate (iCL/P) are at increased risk for reading impairment. The purpose of this study was to evaluate the impact of early risk factors (hearing, speech, and early literacy) on reading performance compared to unaffected participants with average (uAR) and impaired (uIR) reading. Reading achievement and early literacy skills were evaluated across three groups (27 iCL/P, 32 uAR, and 33 uIR). All participants were males, ages 8–11 years old. Those with history of head trauma/injury or major medical/mental health conditions were excluded. Group differences in achievement and early literacy skills were evaluated with ANCOVAs. Participants with impaired reading achievement (at or below 25th Percentile) were identified. Medical record reviews for participates with iCL/P were conducted and audiology and speech ratings recorded. Correlations were calculated between achievement, early literacy, hearing, and speech. Participants with iCL/P had significantly elevated risk for reading impairment (37%); this risk differed by cleft type (0% iCL, 55% iCLP, and 60% iCP). Achievement for participants with iCP was similar to the uIR group. Early literacy risk resulted in lower achievement scores for both iCL/P and unaffected participants. History of inadequate hearing and speech did not significantly impact early literacy or achievement measures. There is a high risk of reading impairment for children with iCL/P—highest for those with iCLP and iCP. Early literacy predictors of reading outcome are similar for iCL/P and idiopathic dyslexia. Current screening and intervention methods are supported.

Distinct effects of visual and auditory temporal processing training on reading and reading-related abilities in Chinese children with dyslexia

Abstract

This study aimed to examine the effects of temporal processing training on the reading abilities of Chinese children with dyslexia. In total, 69 Chinese children with dyslexia in grades three through six were recruited in Taiwan. The children were divided into the following three equal groups: (1) auditory temporal processing training group, (2) visual temporal processing training group, and (3) control group with no specific training. The participants in both training groups received instruction with identical durations (30–40 min), intensities (12 times in total), and frequencies (three to four times per week). The participants in the control group were asked to independently surf some specified websites using devices similar to those used by the two experimental groups for an identical duration, intensity, and frequency. Our results indicated that the two groups who received temporal processing training exhibited significant correlations among Chinese character reading, rapid naming, and corresponding reading-related abilities, while visual temporal processing served as a significant predictor of Chinese character reading ability even if all background data, reading-related abilities, and auditory temporal processing were introduced first. Additionally, significant interactions were found between the Groups and Tested sessions in all the measures, except for phonological awareness, confirming the distinct effects of different temporal processing on most measures involved in this study. Further simple main effects revealed that only those who received the visual temporal processing training gained benefits in the corresponding reading-related ability (i.e., orthographic knowledge) and far-transfer to Chinese character reading.

Children with dyslexia in different cultures: Investigation of anxiety and coping strategies of children with dyslexia in Indonesia and Germany

Abstract

Hitherto the majority of research on anxiety and coping was undertaken on individuals with specific profiles (i.e., individuals with specific difficulties or in cross-cultural settings). However, to our knowledge, no studies have combined cross-cultural and specific difficulty settings to grant a complex analysis of this paradigm nor conducted an investigation of children to reveal the developmental trend in this phenomenon. This study investigates the anxiety profile and coping strategies of children with and without dyslexia from different cultures. A total of 124 children ranging from the age of eight to eleven from Indonesia (n = 64) and Germany (n = 60) were administered a coping and an anxiety scale. Around 50% of the sample were diagnosed with dyslexia and therefore were specifically asked what strategies they implemented in dealing with their difficulties in reading. Findings indicate that dyslexia and cultural factors have distinct contributions in explaining the variance of anxiety and coping strategies. Specifically, dyslexia has a significant effect on separation and generalized anxiety, while an incredible cultural effect is valid for the support-seeking coping strategy. Recommendations for future studies are also discussed.

NL reading skills mediate the relationship between NL phonological processing skills and a foreign language (FL) reading skills in students with and without dyslexia: a case of a NL (Polish) and FL (English) with different degrees of orthographic consistency

Abstract

The aim of our study was to examine the relationship between NL (Native Language: Polish) phonological processing skills (verbal and phonological short-term memory, phoneme segmentation and blending, rapid automatised naming (RAN)) and the accuracy and fluency of NL and English as a Foreign Language (EFL) word and nonword decoding and word recognition skills of Polish students with and without dyslexia. Sixty-three (45%) high school and junior high school students with and 78 (55%) without dyslexia participated. We found that dyslexia, years of studying EFL at school and privately, NL phoneme blending and RAN predicted word reading accuracy in EFL, and dyslexia, years of studying EFL privately, and NL RAN predicted EFL word reading fluency. Dyslexia and NL phoneme blending predicted the accuracy, and NL RAN—the fluency of EFL nonword decoding. These findings confirm that difficulties in FL acquisition result from NL phonological processing deficits, characteristic of dyslexia. Our results also showed relationships between NL phonological processing and EFL reading that were analogical to the ones observed for NL. The pattern of relations between NL phonological processing, NL reading, and EFL reading was similar for reading fluency, but not for reading accuracy in the compared groups. Both NL phonological processing and NL reading facilitated EFL reading, though it was more conspicuous in the control group, which suggests that readers with dyslexia benefit less from their NL reading skills when learning to read in FL.

Introduction: teacher perception, self-efficacy and teacher knowledge relating to literacy

Theory and reported practice in EFL literacy instruction: EFL teachers’ perceptions about classroom practices

Abstract

Acquiring literacy in English as a foreign language (EFL) is important for language development. However, many students enter middle school without adequate EFL literacy skills. This may indicate a gap between EFL literacy instruction theory and the classroom practice that is occurring in elementary school classrooms. The aim of this study was to explore the components of EFL literacy instruction as perceived by teachers. The study investigated whether perceptions of classroom practices are theoretically based, thus shedding light on the gap between EFL literacy theory and practice. The participants were 167 EFL elementary school teachers, who submitted anonymous online questionnaires regarding their reported EFL teaching in year one, two, three, four, and five of elementary school. The research was based on the five pillars of literacy instruction for English as a first language (National Reading Panel, 2000) and additional EFL components (August & Shanahan, 2006). Results of this study showed that EFL teachers expressed views that may indicate a gap between teachers’ practices and most cutting-edge research. The study concluded that providing EFL elementary school teachers with theoretical knowledge may lead to more productive literacy programs and may improve classroom practices.

Explicit linguistic knowledge is necessary, but not sufficient, for the provision of explicit early literacy instruction

Abstract

Teacher’s knowledge can influence the act of teaching and affect children’s learning outcomes. Linguistic and language knowledge of teachers plays an important role in supporting learners at the beginning to read stage. This study examines the language and linguistic knowledge of teachers of beginning readers in New Zealand, how these teachers perceive their own practices in teaching reading, and the relationship with the nature of observed instructional practices. The teachers in the study used predominantly implicit approaches to early reading instruction, with word-level instruction and prompting used only after context, even when teachers with high linguistic knowledge used implicit approaches, suggesting that teacher’s knowledge is not sufficient, on its own, to ensure effective, explicit, word-level instruction to beginning readers.
