Lasting effects on literacy skills with a computer-assisted learning using syllabic units in low-progress readers

This study examines the effects of a computer-assisted learning (CAL) program in which syllabic units were highlighted inside words in comparison with a CAL program in which the words were not segmented, i.e. one requiring whole word recognition. In a randomised control trial design, two separate groups of French speaking poor readers (2 * 14) in first grade were constituted. They were matched on a range of reading measures and non verbal intelligence and trained intensively over a short period (10 h over a period of 5 weeks). Three tasks were proposed using a classical pre-test/training/post-test design, written word recognition, word reading aloud and word spelling. In addition, three post-test sessions were conducted: one just after training, one after 4 months, and a last one after 9 months. The experimental group trained with the CAL using syllabic units outperformed the control group using CAL with whole word recognition in all the three tasks and there were important lasting effects. The results are discussed in the light of the self-teaching hypothesis and phonological recoding.     

Self-regulated learning through writing on computers: Consequences for reading comprehension

The overall aim for the present study was to analyze the consequences for reading ability among the children of a computer supported self-regulated learning environment in grade two. By means of a quasi-experimental design in a natural setting, an experimental group (n = 39) was compared to a control group from a national sample (n = 3409) on reading comprehension. The statistical analyses showed that the experimental group achieved better on reading comprehension both as a group (p < .001) as well as girls (p < .001) and boys (p < .05) separately. The proportion of high achievers was higher, and the proportion of low achievers was lower in the experimental group. In order to explain the level of reading comprehension in the experimental group Structural Equation Modelling (SEM) was used. The main explanatory factor for reading comprehension was writing with β = .44. As a tentative conclusion it was suggested that the extended writing in combination with the self-regulated learning environment can promote reading comprehension in grade two, whereas home literacy had no impact on reading comprehension in this context.     

Reading electronic books as a support for vocabulary,story comprehension and word reading in kindergarten and first grade

The effect of reading an electronic storybook (e-book) on Israeli children’s language and literacy was examined in kindergarten children (N = 40; age 5:2–6:3) compared to first graders (N = 50; age 6:3–7:4). The children in each age group were randomly assigned to two groups: an intervention group which read the e-book five times and a control group which was afforded the regular school program. Pre- and post-tests included vocabulary and word reading measures. Post-tests included story comprehension and production. Children who read the e-book exhibited significant progress in word meaning and word reading compared to the control group. Kindergarten children progressed in word reading more significantly than first graders across treatment groups. This could be explained by the ceiling effect of the first graders’ word reading level which did not leave much room for progress in this skill compared to the kindergarten children. No interaction was found between age and treatment groups. Kindergarten children exhibited a good level of story comprehension, similar to first graders, although their story production was lower. Implications for future research and education are discussed.     

Enhanced recognition of written words and enjoyment of reading in struggling beginner readers through whole-word multimedia software

The effectiveness of a reading intervention using the whole-word multimedia software ‘Oxford Reading Tree (ORT) for Clicker’ was compared to a reading intervention using traditional ORT Big Books. Developing literacy skills and attitudes towards learning to read were assessed in a group of 17 struggling beginner readers aged 5–6 years. Each child was given each of the two interventions, and the order of intervention was counterbalanced across the group. Each intervention was integrated into the literacy hour over five consecutive days. Measures of written word recognition, written word naming, phonological awareness and attitudes towards computers were taken before and after each intervention. Significant gains in performance were found following both interventions for all of the literacy measures, but significantly greater gains in written word recognition and enjoyment of instruction were found following the Clicker than Big Book intervention. These results suggest that whole-word multimedia software could be a useful classroom aid for supporting early literacy skills in children who are struggling with learning to read.     

Reading in the dark: effects of age and contrast on reading speed and comprehension

OBJECTIVE: To explore the effects of contrast reduction on younger and older adults' reading behavior and to examine whether readers rely on word predictability to compensate for poor contrast. BACKGROUND: Poor contrast can degrade text and may influence reading behavior. Readers may compensate for visual degradation of text by taking advantage of word predictability. METHOD: In Experiment 1, 5 younger and 5 older adults read sentences presented with 10 levels of contrast. In Experiment 2, 40 younger and 40 older adults read high-, medium-, and low-contrast sentences that varied in target word predictability (high vs. low). RESULTS: Relative to those of younger adults, older adults' reading rates were more slowed by low contrast; comprehension was less influenced by contrast (i.e., not significantly). Older adults read high-predictability words faster and comprehended them better than low-predictability words, significantly so for high- and medium-contrast sentences. Younger adults comprehended high-predictability words significantly better than low-predictability words for high- and low-contrast sentences. CONCLUSION: Low contrast was more detrimental for older adults. High-predictability words benefited older adults by significantly reducing their reading times and benefited all readers by significantly increasing their comprehension. APPLICATION: The current findings demonstrate the benefit of adequate contrast and word predictability for optimal text design to facilitate both reading times and reading comprehension.     

Enhancing digital reading performance with a collaborative reading annotation system

As children now spend considerable time reading electronic media, digital reading skills and good reading comprehension are essential. However, many studies agree that screen-based reading leads to shallow reading, short attention spans, and poor comprehension. Therefore, this work presents a collaborative reading annotation system with a reading annotation and interactive discussion scaffold (CRAS-RAIDS) for improving reading performance in collaborative digital reading environments. This study used a quasi-experimental design. Fifty-three Grade 5 students were recruited from two classes of an elementary school in Taoyuan County, Taiwan. One class was randomly designated the experimental group used the proposed CRAS-RAIDS support for collaborative reading. The other class was designated the control group and used the traditional paper-based reading annotation method and face-to-face discussions. The two groups were then compared in terms of reading attitude, reading comprehension, and use of reading strategy in an active reading context. Analytical results show that the experimental group significantly outperformed the control group in direct and explicit comprehension, inferential comprehension performance, and use of reading strategy. Moreover, the experimental group, but not the control group, had a significantly improved reading attitude in the total dimensions and in the behavioral and affective sub-dimensions. Additionally, the experimental group showed positive interest and high learning satisfaction.     

ProVoc: An app to train vocabulary depth in order to foster children's reading comprehension

Many studies have demonstrated the crucial role of vocabulary in predicting reading performance in general. More recent work has indicated that one particular facet of vocabulary (its depth) is more closely related to language comprehension, especially inferential comprehension. On this basis, we developed a training application to specifically improve vocabulary depth. The objective of this study was to test the effectiveness of a mobile application designed to improve vocabulary depth. The effectiveness of this training was examined on 3rd and 4th grade children's vocabulary (breadth and depth), decoding and comprehension performances. A randomized waiting-list control paradigm was used in which an experimental group first received the intervention during the first 4 weeks (between pretest and post-test1), thereafter, a waiting control group received the training for the next 4 weeks (between postest1 and posttest2). Results showed that the developed application led to significant improvements in terms of vocabulary depth performance, as well as a significant transfer effect to reading comprehension. However, we did not observe such a beneficial effect on either vocabulary breadth or written word identification. These results are discussed in terms of the links between vocabulary depth and comprehension, and the opportunities the app presents for remedying language comprehension deficits in children.     

Effects of computer-assisted comprehension training in less skilled comprehenders in second grade: A one-year follow-up study

This study examines the effects of a new CAI program designed to remediate text comprehension difficulties in less skilled comprehenders at the beginning of learning to read. In a randomized control trial design, two groups of second grade children experiencing comprehension difficulties were selected and trained using two CAI programs. One of these was designed to assist comprehension processes (experimental group) whereas the other encouraged word decoding (control group). Four tasks were administered using a classical pre-test/training/post-test design: listening comprehension, reading comprehension, vocabulary and comprehension monitoring. In addition, two post-test sessions were conducted: one just after the training and one 11 months later. The experimental group exhibited a greater level of progress in both listening and reading comprehension, with notable lasting effects. In contrast, the results relating to the vocabulary and comprehension monitoring tasks were more mixed. The results are discussed in the light of the possible use of CAI when training higher-level skills such as text comprehension.     

The influence of reading speed and line length on the effectiveness of reading from screen

With such a large volume of material accessible from the World Wide Web, there is an urgent need to increase our knowledge of factors influencing reading from screen. We investigate the effects of two reading speeds (normal and fast) and different line lengths on comprehension, reading rate and scrolling patterns. Scrolling patterns are defined as the way in which readers proceed through the text, pausing and scrolling. Comprehension and reading rate are also examined in relation to scrolling patterns to attempt to identify some characteristics of effective readers. We found a reduction in overall comprehension when reading fast, but the type of information recalled was not dependent on speed. A medium line length (55 characters per line) appears to support effective reading at normal and fast speeds. This produced the highest level of comprehension and was also read faster than short lines. Scrolling patterns associated with better comprehension (more time in pauses and more individual scrolling movements) contrast with scrolling patterns used by faster readers (less time in pauses between scrolling). Consequently, effective readers can only be defined in relation to the aims of the reading task, which may favour either speed or accuracy.     

Variability in reading ability gains as a function of computer-assisted instruction method of presentation

This study examines the effects on early reading skills of three different methods of presenting material with computer-assisted instruction (CAI): (1) learner-controlled picture menu, which allows the student to choose activities, (2) linear sequencer, which progresses the students through lessons at a pre-specified pace, and (3) mastery-based adaptive sequencer, which progresses students through lessons based on whether or not the student has mastered the given skill. Preschool- and kindergarten-aged children (n = 183) were randomly assigned to one of the three CAI groups and spent 40 min a week, for 13 weeks, using the software program in a computer lab. An additional control group of students attending typical preschool or kindergarten received no CAI. ANCOVA results examining post-test reading ability sum score, covarying pre-test score, indicated that the mastery-based sequencer group significantly outperformed the learner-control and control groups, but was not statistically different from the linear sequence group. Analysis by task, rather than overall reading score, revealed significantly better performance for the linear sequence group over controls and picture menu group on the Initial Sound Fluency task, while the mastery-based sequencer group outperformed all three other groups on Non Word Fluency. In sum, these results suggest that the use of a sequencer is a very important element in presenting computerized reading content for young children.     

Real-time lip reading system for isolated Korean word recognition

This paper proposes a real-time lip reading system (consisting of a lip detector, lip tracker, lip activation detector, and word classifier), which can recognize isolated Korean words. Lip detection is performed in several stages: face detection, eye detection, mouth detection, mouth end-point detection, and active appearance model (AAM) fitting. Lip tracking is then undertaken via a novel two-stage lip tracking method, where the model-based Lucas-Kanade feature tracker is used to track the outer lip, and then a fast block matching algorithm is used to track the inner lip. Lip activation detection is undertaken through a neural network classifier, the input for which being a combination of the lip motion energy function and the first dominant shape feature. In the last step, input words are defined and recognized by three different classifiers: HMM, ANN, and K-NN. We combine the proposed lip reading system with an audio-only automatic speech recognition (ASR) system to improve the word recognition performance in the noisy environments. We then demonstrate the potential applicability of the combined system for use within hands free in-vehicle navigation devices. Results from experiments undertaken on 30 isolated Korean words using the K-NN classifier at a speed of 15 fps demonstrate that the proposed lip reading system achieves a 92.67% word correct rate (WCR) for person-dependent tests, and a 46.50% WCR for person-independent tests. Also, the combined audio-visual ASR system increases the WCR from 0% to 60% in a noisy environment.     

Attention-driven read-aloud technology increases reading comprehension in children with reading disabilities

The paper presents the design of an assistive reading tool that integrates read-aloud technology with eye tracking to regulate the speed of reading and support struggling readers in following the text while listening to it. The paper describes the design rationale of this approach, following the theory of auditory–visual integration, in terms of an automatic self-adaptable technique based on the reader's gaze that provides an individualized interaction experience. This tool has been assessed in a controlled experiment with 20 children (aged 8–10 years) with a diagnosis of dyslexia and a control group of 20 children with typical reading abilities. The results show that children with reading difficulties improved their comprehension scores by 24% measured on a standardized instrument for the assessment of reading comprehension and that children with more inaccurate reading (N = 9) tended to benefit more. The findings are discussed in terms of a better integration between audio and visual text information, paving the way to improve standard read-aloud technology with gaze-contingency and self-adaptable techniques to personalize the reading experience.     

A mobile game as a support tool for children with severe difficulties in reading and spelling

We used a randomized controlled trial to investigate if a mobile game, GraphoLearn (GL), could effectively support the learning of first graders (N = 70), who have severe difficulties in reading and spelling. We studied the effects of two versions of the game: GL Reading, which focused on training letter-sound correspondence and word reading; and GL Spelling, which included additional training in phonological skills and spelling. During the spring of first grade, the children trained with tablet computers which they could carry with them during the six-week intervention. The average exposure time to training was 5 hr 44 min. The results revealed no differences in the development of reading or spelling skills between GL players and the control group. However, pre-training self-efficacy moderated the effect among GL Reading players: children with high self-efficacy developed more than the control group in word reading fluency, whereas children with low self-efficacy developed less than the control group in spelling.     

Enhancement of digital reading performance by using a novel web-based collaborative reading annotation system with two quality annotation filtering mechanisms

Collaboratively annotating digital texts allows learners to add valued information, share ideas, and create knowledge. However, excessive annotations and poor-quality annotations in a digital text may cause information overload and divert attention from the main content. The increased cognitive load ultimately reduces the effectiveness of collaborative annotations in promoting reading comprehension. Thus, this work develops a web-based collaborative reading annotation system (WCRAS-TQAFM) with two quality annotation filtering mechanisms—high-grade and master annotation filters—to promote the reading performance of learners. Ninety-seven students from three classes of a senior high school in Taiwan were invited to participate in an 80-min reading activity in which individual readers use WCRAS with or without annotation filters. Analytical results indicate that digital reading performance is significantly better in readers who use the high-grade annotation filter compared to those who read all annotations. Moreover, the high-grade annotation filter can enhance the reading comprehension of learners in all considered question types (i.e., recall, main idea, inference, and application). Also, the Cohen’s kappa statistics was used for assessing whether the annotation selected by the high-grade annotation filter is in agreement with the annotations selected by a domain expert. The statistic results indicate that the proposed high-grade annotation filter is valid to some degree. Finally, neither of the proposed quality annotation filtering approaches significantly reduces cognitive load.     

片段抽取型机器阅读理解算法研究

Audio-visual training in children with reading disabilities

This study tested the effectiveness of audio-visual training in the discrimination of the phonetic feature of voicing on the recognition of written words by young children deemed to at risk of dyslexia (experiment 1) as well as on dyslexic children’s phonological skills (experiment 2). In addition, the third experiment studied the effectiveness of this word recognition training in dyslexic children who regularly used a computer at home. A traditional pre-test, training, post-test design including comparison groups (experimental vs. control) provided a base-line for assessing the training effects. In the three experiments the intervention group showed higher increases performances in phonological skills and phonological recoding than the control group did. Beyond providing evidence for the effectiveness of this audio-visual training, these results contribute to an understanding of the nature of reading difficulties and successful training. Globally, the results show the impact of the audio-visual training about voicing on performances of reading-disabled children. A such type of training leads children to connect print and phonology. Phonological representations could be specified by training which involves both phonological and orthographic units. The mapping between these two units could be easier in a computerized remedial program.     

Moderating role of reading comprehension in children's word learning with context versus pictures

We investigated pictorial versus contextual support effects over and above teaching of definitions on children's word learning and retention as well as the moderating role of reading comprehension. In a between-subject pre-post-retention test control group design, Dutch fourth graders learned concrete and abstract Dutch words. The context group received definitions and context sentences, the picture group received definitions and pictures, and the control group only received definitions. Children in the picture group outperformed children in the context group but not the control group on all words directly after learning. This learning gain, however, disappeared over time because participants in the context group retrieved the word meanings better than in the other groups 1 day later. Interestingly, reading comprehension moderated the forgetting effect, as low comprehenders in the experimental groups forgot less than those in the control group. Adding pictures to definitions, thus, leads to richer long-term knowledge for low comprehenders.     

Responsiveness to a game-based intervention to enhance reading efficiency in first graders

In the present study, a 5-week tablet-based word reading efficiency game intervention (Reading Turbo) was integrated in a comprehensive phonics-based reading curriculum. The aims of the study were to examine whether the game would advance children's word reading efficiency, and to determine the extent to which pre-reading capacities and in-game mechanisms could explain individual variation in responsiveness to the game. To do so, word reading efficiency scores of first graders in an intervention group (n = 132) and a control group that continued with the usual reading curriculum (n = 118) were compared prior to, directly after, and 2 months after the 5-week intervention period. Individual variation in responsiveness was examined by relating reading precursors (i.e., phonological awareness, letter efficiency, rapid automatized naming (RAN), and verbal working memory) measured at the onset of the intervention, and in-game accuracy and efficiency to word reading efficiency outcomes in untrained words. Results indicated that playing the word reading game significantly enhanced first graders' word reading efficiency directly after the intervention, but the effect was no longer significant 2 months after the intervention. With respect to individual variation in game responsiveness, it was found that phonological awareness, letter efficiency, and verbal working memory predicted responsiveness to the game via in-game accuracy. In addition, phonological awareness and RAN predicted responsiveness to the game via in-game efficiency, and letter efficiency and verbal working memory were directly related to responsiveness. The effectiveness of the word reading game thus differentiated between children with higher and lower pre-reading capacities, and operated via in-game child affordances.
