Expository paragraph writing is difficult to learn and teach. For many students, particularly those with learning disabilities, it is difficult to manage the multiple, simultaneous complex processes required for success. And for their teachers, writing is the content area in which they feel least prepared to teach. This intervention applied the concept of reverse engineering to instructional design to teach expository paragraph writing using a color-cued graphic organizer. The study evaluated the effects of using a systematic color code to highlight the alignment of where ideas originate in a graphic organizer to their development into a sentence within a well-organized expository paragraph. Using a single case research design, with a pre- and post-intervention assessments, students (n = 5) with dyslexia improved their expository paragraph knowledge and skills. Percentage of non-overlapping data and Tau analyses indicate a large to very large effect of the 2-week intervention. Results, suggestions for further research, and implications for practice are discussed.

Reading and spelling skills are important to communicate in today's literate society, however, the underlying processes of spelling skills are under-researched compared to reading skills. Our goals were to (a) study how the component skills of phonological, orthographic and morphological awareness are different in adults with and without reading difficulties, and (b) characterize the relationship between the component skills and reading and spelling performance in both skilled and poor readers. Participants (N = 37, N = 15 with reading impairments and N = 22 skilled readers) took part in the study where they completed several literacy-based measures. We performed a series of mixed ANOVAs to study the between-group differences in performance and the relationship between different literacy outcomes, respectively. We found evidence for poor phonological and morphological awareness in the poor readers compared to the skilled readers. We also found differential relationships between the component skills and reading and spelling behavior. Specifically, sound awareness was significantly related to reading and spelling measures in the skilled readers, whereas morphological and sound awareness played an important role in the same skills in the poor readers. We discuss these findings in the context of potential remediation strategies for adults with persistent literacy impairments.

Accelerated reader (AR) is a computerized reading program commonly used in schools. The program aims to enhance students' reading achievement and encourage students to read more through goal setting and frequent reading practice. A meta-analytic review of the AR was conducted to analyse its effectiveness as an evidence-based intervention for improving student reading achievement, attitude, and motivation. This study investigated potential moderating variables, including publication type, participant, and study characteristics that impact student reading outcomes. A total of 44 studies from peer-reviewed journal articles and dissertations met the inclusion criteria. Participants included 16,653 students enrolled in elementary, middle, and high school. Hedges' g effect sizes measures suggest pretest–posttest one-group AR studies have moderate effects (g = 0.541) while comparison group AR studies have marginal effects (g = 0.278). A meta-regression model of six potential categorical moderators of comparison group studies indicted no significant moderators. Implications and the need for further research regarding evidence-based and culturally appropriate reading interventions are discussed.

Children with dyslexia, compared with typically reading peers, are at increased risk of internalising (e.g., anxiety) and externalising (e.g., aggression) mental health concerns; why this is the case is largely unknown. Our aim was to explore the socio-emotional experience of growing up with dyslexia from both child and parent perspectives. In so doing, we aimed to gain a better understanding of self-esteem and mental health in the context of dyslexia. One-to-one semi-structured interviews with 17 children with reading difficulties (aged 9–14 years; 16 with a diagnosis of dyslexia) and their mothers (interviewed separately) were analysed using Braun and Clarke's reflexive thematic analysis approach with a neurodiversity lens. We developed three themes to address the research aim: (1) Different in a good/bad way; (2) Exhausted and overwhelmed; and (3) It takes a community: Family school connections. Children discussed having “worries” and experiencing school-related stress and embarrassment. Mothers perceived children's internalising and externalising behaviour (meltdowns), school refusal, and homework resistance as emotional responses to children's school struggles due to poor “person-environment fit.” Our analysis highlights the particular importance of parent support, friendship, and school-connectedness for the wellbeing of children with dyslexia.

In many countries, intervention costs are not covered by public health care. A critical basis for deciding whether an intervention is covered or not is to analyse the relation between benefits and costs of the intervention, and to quantify the consequential costs. In this study, a cost-utility analysis was computed to investigate the costs of individualized dyslexia intervention while quantifying the benefit in terms of health-related quality of life in a sample of 36 individuals with dyslexia. In addition, educational outcomes and costs of untreated dyslexia for the society were estimated using information for class repetition, school success, and unemployment rates from previous studies and official statistics. A significant increase in quality of life with medium effect sizes was found across all quality-of-life measures. Increases in quality of life were domain-specific, thus occurring specifically in those domains that are affected by learning disorders. The cost-utility ratio was 9,782 Euros per quality adjusted life years (QALYs), which is in line with similar therapy forms, such as speech therapy. The loss of productivity for untreated dyslexia in the German population was estimated for class repetition and reduced income due to lower school degrees. The cost-utility analysis and the calculation of consequential costs suggest that the dyslexia intervention is cost-effective.

Children with dyslexia are at risk of poor academic attainment and lower life chances if they do not receive the support they need. Alongside phonics-based interventions which already have a strong evidence base, specialist dyslexia typefaces have been offered as an additional or alternative form of support. The current study examined whether one such typeface, Dyslexie, had a benefit over a standard typeface in identifying letters, reading words, and reading passages. 71 children, aged 8–12 years, 37 of whom had a diagnosis of dyslexia, completed a rapid letter naming task, a word reading efficiency task, and a passage reading task in two typefaces, Dyslexie and Calibri. Spacing between letters and words was kept constant. Results showed no differences in word or passage reading between the two typesfaces, but letter naming did appear to be more fluent when letters were presented in Dyslexie rather than Calibri text for all children. The results suggest that a typeface in which letters are designed to be distinctive from one another may be beneficial for letter identification and that an intervention in which children are taught letters in a specialist typeface is worthy of consideration.

Dorsal stream is an important pathway for visual information transmission. As a part of the dorsal pathway, the middle temporal visual motion areas (V5/MT+) are mainly responsible for visual motion processing and the ability of visual motion processing is closely related to reading. Compared with alphabetic scripts, the visual structure of Chinese characters is more complex and there are no clear grapheme-phoneme correspondence rules. So the ability of visual analysis plays an important role in Chinese character processing. This study first investigated the brain activation of Chinese dyslexic children and children of the same chronological age when they observed coherent motion stimuli. ROI analysis indicated that only the activation of left V5/MT+ was significantly weaker in dyslexics than that in the control group. The activity of the magnocellular-dorsal stream was closely related to orthographic awareness in the combined data (two groups) and the typical children. In dyslexia group, the stronger the activation of V5/MT+ was, the worse the phonological awareness, rapid naming performance and orthographic awareness were. In short, Chinese dyslexic children were deficient in the activation of the left V5/MT+ and the activity of the magnocellular-dorsal pathway was closely related to orthographic awareness in Chinese pupils.

Magnocellular (M) deficit theory indicates that individuals with developmental dyslexia (DD) have low sensitivity to stimuli with high temporal frequencies (HTF) and low spatial frequencies (LSF). However, some studies found that temporal processing and spatial processing were correlated with different reading-related skills. Chinese is a logographic language, and visual skills are particularly important for reading in Chinese. It is necessary to investigate the temporal and spatial processing abilities in the M pathway of Chinese children with DD. Using electrophysiological recordings, the present study examined the mean amplitude and latency of P1 during a grating direction judgment task in 13 children with DD and 13 age-matched normal children. Dyslexic children showed a low amplitude and long latency of P1 in the HTF condition and LSF condition compared with age-matched children. In the HTF condition, the amplitude of P1 correlated with phonological awareness, and the latency of P1 correlated with reading fluency and rapid naming of digits. The amplitude of P1 in the LSF condition correlated with reading accuracy. This result suggested that Chinese children with DD had difficulties in both temporal and spatial processing in the M pathway. However, temporal processing and spatial processing played different roles in Chinese reading.

The aim of the study was to examine the accuracy of Estonian teachers' and support specialists' judgements of students' spelling skills and reading fluency and to investigate the provision of special education services to students as a factor influencing teachers' judgements. The sample included 11 classroom teachers, 8 support specialists, and 187 third-grade students. The judgements were collected using scales, and students' literacy skills were assessed using group and individual tests. The results indicated that judgements of reading fluency were less accurate than those of spelling skills. In addition, the provision of special education services influenced teachers' judgements, directing them to identify students in need of help, even if the teacher did not initially assign the student to the low-skilled group. Unexpectedly, teachers' judgements of the skills of students receiving special education services were slightly more accurate than support specialists' judgements.
