ABSTRACT
Large multi-site studies that combine magnetic resonance imaging (MRI) data across research sites present exceptional opportunities to advance neuroscience research. However, scanner or site variability and non-standardised image acquisition protocols, data processing and analysis pipelines can adversely affect the reliability and repeatability of MRI derived brain measures. We implemented a standardised MRI protocol based on that used in the Adolescent Brain Cognition Development (ABCD)â study in two sites, and across four MRI scanners. Twice repeated measurements of a single healthy volunteer were obtained in two sites and in four 3T MRI scanners (vendors: Siemens, Philips, and GE). Imaging data included anatomical scans (T1 weighted, T2 weighted), diffusion weighted imaging (DWI) and resting state functional MRI (rs-fMRI). Standardised containerized pipelines were utilised to pre-process the data and different image quality metrics and test-retest variability of different brain metrics were evaluated. The implementation of the MRI protocols was possible with minor adjustments in acquisition (e.g. repetition time (TR), higher b-values) and exporting (DICOM formats) of images due to different technical performance of the scanners. This study provides practical insights into the implementation of standardised sequences and data processing for multisite studies, showcase the benefits of containerised preprocessing tools, and highlights the need for careful optimisation of multisite image acquisition.
ABSTRACT
The study examined the effect of reciprocal teaching on students' reading comprehension, reading fluency, and metacognitive knowledge of reading strategies, especially among students with learning difficulties. The special focus was to assess how the increase in reading fluency and metacognitive knowledge during the intervention contributes to the reading comprehension outcome. The sample consisted of 301 Grade 3 students, of whom 77 had learning difficulties. Analyzes of (co)variances were used for estimating the effects of reciprocal teaching on the development of reading comprehension, reading fluency, and metacognitive knowledge. Multigroup path analysis was used for testing the effect of increase in reading fluency and metacognitive knowledge on reading comprehension. We found reciprocal teaching had a positive effect on reading comprehension, especially for students with learning difficulties. Reading fluency and metacognitive knowledge improved significantly, but similarly in both the intervention and control groups. However, the increase in metacognitive knowledge only contributed to reading comprehension in the intervention group, not in the control group. The study sheds light on the cognitive and metacognitive mechanisms underlying students' reading comprehension process, emphasizing metacognitive knowledge and especially the systematic practice of reading strategies as key factors in improving reading comprehension.
ABSTRACT
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.

Studies have found math anxiety and achievement to be related from the beginning of formal schooling, but the knowledge regarding the direction of the relationship is vague. The purpose of the present study was to study this relationship. We investigated math anxiety from two points of view: trait and state anxiety. In the first substudy, we investigated the longitudinal relationship between math anxiety and performance from sixth to seventh grade (n = 848) with cross-lagged modeling. In the second substudy, we investigated the situational relationship of anxiety and performance by giving the participants (n = 149) challenging and nonchallenging math tasks adapted to their skill level, and then examining the association between anxiety and the performance. The results suggest that math anxiety has a small longitudinal effect on performance: High anxiety in sixth grade predicted low performance in seventh grade. Anxiety also had a situational association with performance: when anxiety was aroused, the participants performed more poorly compared to their skill level. The results adduce the two-fold effect of anxiety on achievement: math anxiety seems to have both a real-time association with performance and a long-term effect on the development of basic arithmetic skills.

This study examined the malleability of math self-efficacy (SE) among children with poor calculation fluency via an intervention that targeted four sources of SE (mastery experiences, vicarious experiences, social persuasions, and emotional and physiological states). The effect of pure strategy training was contrasted with an intervention that integrated strategy training and explicit SE support. Moreover, the changes in SE source experiences and their relation with math SE, as well as the relation between math-SE profiles and calculation fluency development, were examined. In a quasi-experimental design, 60 Finnish children with calculation fluency problems in Grades 2 to 4 participated in strategy training (N = 38) or in an intervention that integrated SE support with strategy training (N = 32) for 12 weeks. The results showed that the explicit SE intervention integrated with strategy training enhanced math SE among children with poor calculation fluency and low SE (effect size, r = 0.61). Changes in mastery experiences and social persuasions were positively associated with changes in math SE among children who received the explicit SE intervention. An initially high math-SE profile and a profile indicating an increase from low to high math SE were related to growth in calculation fluency that approached the children's average age level during the interventions. In conclusion, an integrated approach that combined skill training and SE intervention was especially beneficial for children with poor calculation fluency and low math SE.
ABSTRACT
This study examines the core predictors of the covariance in reading and arithmetic fluency and the domain-general cognitive skills that explain the core predictors and covariance. Seven-year-old Finnish children (N = 200) were assessed on rapid automatized naming (RAN), phonological awareness, letter knowledge, verbal counting, number writing, number comparison, memory skills, and processing and articulation speed in the spring of Grade 1 and on reading and arithmetic fluency in the fall of Grade 2. RAN and verbal counting were strongly associated, and a constructed latent factor, serial retrieval fluency (SRF), was the strongest unique predictor of the shared variance. Other unique predictors were phonological awareness, number comparison, and processing speed. Findings highlight the importance of SRF in clarifying the relation between reading and arithmetic fluency.

India, a country with a population of more than 1.3 billion individuals, houses the world's second largest educational system. Despite this, 100 of millions of individuals in India are still illiterate. As English medium education sweeps the country, many are forced to learn in a language which is foreign to them. Those living in poverty further struggle to learn English as it tends to be a language which they have no prior exposure to and no support at home for. Low-quality schools and poor instructional methods further exacerbate the problem. Without access to quality education, these individuals continue to struggle and are ultimately never given the chance to break the cycle of poverty. The aim of this study was to determine whether GraphoLearn, a computer-assisted reading tool, could be used to support the English reading skills of struggling readers in India. Participants were 7-year-old, grade 3 students (N = 30), who were attending an English-medium public school in Ahmedabad, India. English was not a native language for any of the students and all were reading at a level below that of Grade 1 despite having attended school for 2 years. Half of the students played GraphoLearn (n = 16) while the other half played a control math game (n = 14) for 20-30 min a day, over a period of 8 weeks. GraphoLearn led to significant improvements in children's letter-sound knowledge, a critical factor in early reading development. Overall, the study opens doors for GraphoLearn as a potential intervention to support struggling readers of English in India, including those who are learning a non-native language and coming from at-risk backgrounds.
ABSTRACT
The aim of the present study was to extend the previous intervention research in math by examining whether elementary school children with poor calculation fluency benefit from strategy training focusing on derived fact strategies and following an integrative framework, i.e., integrating factual, conceptual, and procedural arithmetic knowledge. It was also examined what kind of changes can be found in frequency of using different strategies. A quasi-experimental design was applied, and the study was carried out within the context of the school and its schedules and resources. Twenty schools in Finland volunteered to participate, and 1376 children were screened in for calculation fluency problems. Children from second to fourth grades were recruited for the math intervention study. Children with low performance (below the 20th percentile) were selected for individual assessment, and indications of using counting-based strategies were the inclusion criteria. Altogether, 69 children participated in calculation training for 12 weeks. Children participated in a group based strategy training twice a week for 45 min. In addition, they had two short weekly sessions for practicing basic addition skills. Along with pre- and post-intervention assessments, a 5-month follow-up assessment was conducted to exam the long-term effects of the intervention. The results showed that children with dysfluent calculation skills participating in the intervention improved significantly in their addition fluency during the intervention period, showing greater positive change than business-as-usual or reading intervention controls. They also maintained the reached fluency level during the 5-month follow-up but did not continue to develop in addition fluency after the end of the intensive training program. There was an increase in fact retrieval and derived fact/decomposition as the preferred strategies in math intervention children and a decrease of the use of counting-based strategies, which were the most common strategies for them before the intervention. No transfer effect was found for subtraction fluency.
ABSTRACT
Response to Intervention (RTI) was accepted in the early 2000s as a new framework for identifying learning difficulties (LD) in the U.S. In Finland, a similar multi-tiered framework has existed since 2010. In the present study, these frameworks are presented from the viewpoint of the role of assessment and instruction as expressed in documents that describe the frameworks, as it seems that these two components of RTI are the most disparate between the U.S. and Finland. We present a suggestion for the Finnish framework as an example of support in mathematics learning that incorporates principles of RTI (such as systematized assessment and instruction, cyclic support, and modifiable instruction). Finally, recommendations are presented for further refining and developing assessment and instruction policies in the two countries.
ABSTRACT
BACKGROUND: Children have been found to report and demonstrate math anxiety as early as the first grade. However, previous results concerning the relationship between math anxiety and performance are contradictory, with some studies establishing a correlation between them while others do not. These contradictory results might be related to varying operationalizations of math anxiety. AIMS: In this study, we aimed to examine the prevalence of math anxiety and its relationship with basic arithmetic skills in primary school children, with explicit focus on two aspects of math anxiety: anxiety about failure in mathematics and anxiety in math-related situations. SAMPLE: The participants comprised 1,327 children at grades 2-5. METHODS: Math anxiety was assessed using six items, and basic arithmetic skills were assessed using three assessment tasks. RESULTS: Around one-third of the participants reported anxiety about being unable to do math, one-fifth about having to answer teachers' questions, and one tenth about having to do math. Confirmatory factor analysis indicated that anxiety about math-related situations and anxiety about failure in mathematics are separable aspects of math anxiety. Structural equation modelling suggested that anxiety about math-related situations was more strongly associated with arithmetic fluency than anxiety about failure. Anxiety about math-related situations was most common among second graders and least common among fifth graders. CONCLUSIONS: As math anxiety, particularly about math-related situations, was related to arithmetic fluency even as early as the second grade, children's negative feelings and math anxiety should be identified and addressed from the early primary school years.

The purpose of this study was twofold: (a) to contrast the prominent theoretical explanations of the rapid automatized naming (RAN)-reading relationship across languages varying in orthographic consistency (Chinese, English, and Finnish) and (b) to examine whether the same accounts can explain the RAN-spelling relationship. In total, 304 Grade 4 children (102 Chinese-speaking Taiwanese children, 117 English-speaking Canadian children, and 85 Finnish-speaking children) were assessed on measures of RAN, speed of processing, phonological processing, orthographic processing, reading fluency, and spelling. The results of path analysis indicated that RAN had a strong direct effect on reading fluency that was of the same size across languages and that only in English was a small proportion of its predictive variance mediated by orthographic processing. In contrast, RAN did not exert a significant direct effect on spelling, and a substantial proportion of its predictive variance was mediated by phonological processing (in Chinese and Finnish) and orthographic processing (in English). Given that RAN predicted reading fluency equally well across languages and that phonological/orthographic processing had very little to do with this relationship, we argue that the reason why RAN is related to reading fluency should be sought in domain-general factors such as serial processing and articulation.

This study explored the double-deficit hypothesis (DDH) in a transparent orthography (Finnish) and extended the view from reading disabilities to comorbidity of learning-related problems in math and attention. Children referred for evaluation of learning disabilities in second through sixth grade (N = 205) were divided into four groups based on rapid automatized naming (RAN) and phonological awareness (PA) according to the DDH: the double-deficit group, the naming speed deficit-only group, the phonological deficit-only group, and the no-deficit group. The results supported the DDH in that the prevalence and severity of reading disability were greatest in the double-deficit group. Despite the greater prevalence of reading disabilities in single-deficit groups compared to the no-deficit group, the means of reading measures in the single-deficit groups were similar to those of the no-deficit group. The PA single-deficit group was poorer in spelling than the no-deficit group and single-naming-deficit group. Deficits in RAN or PA were primarily linked to reading disabilities but not with math or attention problems. The results supported the DDH partially and indicate that deficits in RAN and PA are specific to reading disabilities.

The aim of the study was to explore the Finnish preservice and inservice teachers' knowledge of language constructs relevant for literacy acquisition. A total of 150 preservice teachers and 74 inservice teachers participated in the study by filling out a questionnaire that assessed self-perceived expertise in reading instruction, knowledge of phonology and phonics, and knowledge of morphology. The inservice teachers outperformed the preservice teachers in knowledge of phonology and phonics, as well as morphology. Both groups' knowledge of morphology was markedly lower than their knowledge of phonology and phonics. Because early reading instruction does not focus on the morphological level of language but is phonics-based, this result was expected. However, the findings also revealed a lack of explicit knowledge of basic phonological constructs and less-than-optimal phonemic awareness skills in both groups. Problems in phonemic skills manifested mostly as responding to the phonological tasks based on orthographic knowledge, which reflects an overreliance on the one-to-one correspondence between graphemes and phonemes. The preservice teachers' perceptions of expertise were weakly related to their knowledge and skills. Among the inservice teachers, perceived expertise and knowledge of language constructs were completely unrelated. Although the study was exploratory, these findings suggest that within the Finnish teacher education there is a need to focus more on explicit content studies for language structures and the concepts relevant for literacy instruction, as well as phonological and phonemic skills.

In previous eye movement research on word length effects, spatial width has been confounded with the number of letters. McDonald (2006) unconfounded these factors by rendering all words in sentences in constant spatial width. In the present study, the Arial font with proportional letter spacing was used for varying the number of letters while equating for spatial width, while the Courier font with monospaced letter spacing was used to measure the contribution of spatial width to the observed word length effect. Number of letters in words affected single fixation duration on target words, whereas words' spatial width determined fixation locations in words and the probability of skipping a word. The results support the existence of distinct subsystems for deciding where and when to move eyes in text (Rayner & McConkie, 1976). The number-of-letters effect in fixation duration may be explained by visual acuity, visual crowding, and/or serial letter processing.

AIM: The aim of this study was to examine the connection between balance problems and reading speed in children with and without a familial risk of dyslexia by controlling for the effects of attention, hyperactivity, and cognitive and motor functioning. METHOD: The prevalence of balance problems was studied in 94 children (48 females, 46 males) with a familial risk of dyslexia (at-risk group) and 85 children (38 females, 47 males) without a risk of dyslexia (comparison group). Further, the relationships between balance problems (at age 8y 6mo), reading proficiency (at age 9y), attention-deficit-hyperactivity disorder (at age 8y), and cognitive (at age 8y 6mo) and motor functioning (at age 6y 6mo) were examined. Inclusion criteria for the at-risk group were that at least one parent had a confirmed reading problem and one or more of the parents' close relatives also had a reading problem. The Good Balance System was used to assess static standing balance, word-list and text reading tasks were used to measure reading proficiency. The Behavioural Assessment System for Children - Parent Rating Scale was used to assess attention-deficit-hyperactivity disorder, the Wechsler Intelligence Scale for Children was used to assess cognitive functioning, and the Movement Assessment Battery for Children was used to measure motor functioning. RESULTS: Balance (F((1,177)) =4.82; p=0.029; =0.027) and reading (F((1,176)) =11.95; p=0.001; =0.064) problems were more common in the at-risk group than in the comparison group. Furthermore, attention, hyperactivity, IQ, and motor functioning were not related to balance problems. However, attention (F((1,154)) =10.80; p=0.001; =0.066) and IQ (F((1,170)) =22.08; p<0.001; =0.115) were individually connected to reading speed. INTERPRETATION: Balance problems alone could not produce any differences in reading skills. Instead, both balance problems and reduced reading skills were mainly associated separately with a familial risk of dyslexia. This indicates that there may be a shared genetic mechanism between balance and reading problems.

This work is an extension of a study by Waber, Wolff, Forbes, and Weiler (2000 ) in which the specificity of naming speed deficits to reading disability (RD) was examined. One hundred ninety-three children (ages 8 to 11) evaluated for learning disabilities were studied. It was determined how well rapid automatized naming (RAN) discriminated between different diagnostic groups (learning impaired [LI] with and without RD) from controls and from each other. Whereas Waber et al. concluded that RAN was an excellent tool for detecting risk for learning disabilities in general, the results of the present study point to a more specific connection between RAN and RD.

Outcomes of two training programs aimed at improving reading speed for 39 German-speaking poor readers in grades 2 and 4 were evaluated. During a 6-week training period, a specific target for children in a computer group was to improve reading of word-initial consonant clusters by practice in associating an orthographic unit with a corresponding phonological unit. Children in a paired reading group read books with an adult tutor. The results showed that, in reading words in which the computer-trained sublexical items were included, both groups exhibited similar improvement. A post hoc analysis suggested that computer training was associated with better reading skills with respect to the trained sublexical items; however, this improvement did not show large generalization effects to the words with the sublexical items. The paired reading group showed a more rapid gain in global word reading fluency than the computer group. Neither of the groups improved their pseudoword reading.

The authors examined second grade reading accuracy and fluency and their associations via letter knowledge to phonological and language predictors assessed at 3.5, 4.5, and 5.5 years in children in the Jyväskylä Longitudinal Study of Dyslexia. Structural equation modeling showed that a developmentally highly stable factor (early phonological and language processing [EPLP]) behind key dyslexia predictors (i.e., phonological awareness, short-term memory, rapid naming, vocabulary, and pseudoword repetition) could already be identified at 3.5 years. EPLP was significantly associated with reading and spelling accuracy and by age with letter knowledge. However, EPLP had only a minor link with reading fluency, which was additionally explained by early letter knowledge. The results show that reading accuracy is well predicted by early phonological and language skills. Variation in fluent reading skills is not well explained by early skills, suggesting factors other than phonological core skills. Future research is suggested to explore the factors behind the development of fast and accurate decoding skills.

Outcomes of three different types of computerized training in sub-lexical items (word-initial consonant clusters) on reading speed for 39 German-speaking poor readers in Grades 2 and 3 were evaluated. A phonological-orthographic association group, a reading aloud group, and a combined group were compared in performance with an untrained control group. During short-term training, the intervention groups showed higher gains than the control group in reading speed of the trained sub-lexical items and of the words containing the trained segments. No differences were found between the intervention groups. In the development of pseudoword reading, the groups did not show differential improvements. The generalization effect to pseudoword reading was similar, whether the pseudowords contained the trained segment as a syllable or as a non-syllabic letter string. The gains induced by training were specific to the materials used in training and did not induce gains in general reading speed.

BACKGROUND: Analyses from the Jyväskylä Longitudinal Study of Dyslexia project show that the key childhood predictors (phonological awareness, short-term memory, rapid naming, expressive vocabulary, pseudoword repetition, and letter naming) of dyslexia differentiate the group with reading disability (n = 46) and the group without reading problems (n = 152) at the end of the 2nd grade. These measures were employed at the ages of 3.5, 4.5 and 5.5 years and information regarding the familial risk of dyslexia was used to find the most sensitive indices of an individual child's risk for reading disability. METHODS: Age-specific and across-age logistic regression models were constructed to produce the risk indices. The predictive ability of the risk indices was explored using the ROC (receiver operating curve) plot. Information from the logistic models was further utilised in illustrating the risk with probability curve presentations. RESULTS: The logistic regression models with familial risk,letter knowledge, phonological awareness and RAN provided a prediction probability above .80 (area under ROC). CONCLUSIONS: The models including familial risk status and the three above-mentioned measures offer a rough screening procedure for estimating an individual child's risk for reading disability at the age of 3.5 years. Probability curves are presented as a method of illustrating the risk.
