Performance across different areas of mathematical cognition in children with learning difficulties.

The performance of 210 2nd graders in different areas of mathematical cognition was examined. Children were divided into 4 achievement groups: children with difficulties in mathematics but not in reading (MD-only), children with difficulties in both mathematics and reading (MD/RD), children with difficulties in reading but not in mathematics, and children with normal achievement. Although both MD groups performed worse than normally achieving groups in most areas of mathematical cognition, the MD-only group showed an advantage over the MD/RD group in exact calculation of arithmetic combinations and in problem solving. The 2 groups did not differ in approximate arithmetic and understanding of place value and written computation. Children with MD-only seem to be superior to children with MD/RD in areas that may be mediated by language but not in ones that rely on numerical magnitudes, visuospatial processing, and automaticity.

Skill development in different components of arithmetic and basic cognitive functions: Findings from a 3-year longitudinal study of children with different types of learning difficulties.

Arithmetic and cognitive skills of children with mathematical difficulties (MD-only), with comorbid reading difficulties (MD-RD), with reading difficulties (RD-only), and normally achieving children were examined at 3 points from Grades 3–4 to Grades 5–6 (age range, 9–13 years). Both MD groups displayed severe weaknesses in 4 domain-specific arithmetic components (factual, conceptual, procedural, and problem-solving skills) during all 3 measure points. Telling time and approximate arithmetic were also problematic for children with MD. Both MD groups displayed a small weakness related to visual–spatial working memory, and the MD-RD group also displayed small weaknesses related to verbal short-term memory, processing speed, and executive functions. The 4 groups developed at similar rates within all domain-specific components as well as basic cognitive functions. These findings demonstrate that children identified as having MD when they are 9 years old do not catch up with their normally achieving peers in later school grades, when they are 13 years old. They also continue to lag behind their peers with respect to the domain-general cognitive system. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Achievement growth in children with learning difficulties in mathematics: Findings of a two-year longitudinal study.

The reading and mathematics growth of 180 children was examined over 4 points, spanning 2nd and 3rd grades. Initially, 4 achievement groups were identified: difficulties in mathematics but not in reading (MD only), difficulties in mathematics as well as in reading (MD-RD), difficulties in reading hut not in mathematics (RD only), and normal achievement in mathematics and in reading. When IQ, income, ethnicity, and gender were held constant, the MD-only group grew at a faster rate in mathematics than did the MD-RD group. In reading, the RD-only and MD-RD groups grew at about the same rate. Reading abilities influence children's growth in mathematics, but mathematics abilities do not influence children's growth in reading.

Psycho-motor re-education for children with reading difficulties.

Psycho-motor re-education is a specialized pedagogical treatment based on movement. There are many instances in which a psychomotor re-education is indicated. We will deal today with the cases of children suffering of reading difficulties and a way in which psychomotor re-education can help these children. The objective of psycho-motor re-education is to give by true concrete approach an occasion to the child of experimenting and developing his motricity, his body image and his spatial organization. In those cases in which psycho-motor troubles have been directly or indirectly the cause of learning disabilities, this method of re-education has proven itself valuable, especially if integrated in a body of treatments. Its usefulness comes from the fact that the re-education attacks directly the psycho-motor difficulties and thus allows a motor and spatial reorganization, thus is prevented the existence of "holes" which have to be patched continuously when more scholarly treatment is undertaken. It also allows through a narrow cooperation with corrective teaching the facilitation of constant references to actual learning experiences on the concrete level. There are still of course many unknowns, but we believe that the inter-disciplinary dialogue will be evermore in a position to answer them and to discover them.

More on the Fragility of Performance: Choking Under Pressure in Mathematical Problem Solving.

In 3 experiments, the authors examined mathematical problem solving performance under pressure. In Experiment 1, pressure harmed performance on only unpracticed problems with heavy working memory demands. In Experiment 2, such high-demand problems were practiced until their answers were directly retrieved from memory. This eliminated choking under pressure. Experiment 3 dissociated practice on particular problems from practice on the solution algorithm by imposing a high-pressure test on problems practiced 1, 2, or 50 times each. Infrequently practiced high-demand problems were still performed poorly under pressure, whereas problems practiced 50 times each were not. These findings support distraction theories of choking in math, which contrasts with considerable evidence for explicit monitoring theories of choking in sensorimotor skills. This contrast suggests a skill taxonomy based on real-time control structures. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Enhancing third-grade student' mathematical problem solving with self-regulated learning strategies.

The authors assessed the contribution of self-regulated learning strategies (SRL), when combined with problem-solving transfer instruction (L. S. Fuchs et al., 2003), on 3rd-graders' mathematical problem solving. SRL incorporated goal setting and self-evaluation. Problem-solving transfer instruction taught problem-solution methods, the meaning of transfer, and 4 superficial-problem features that change a problem without altering its type or solution; it also prompted metacognitive awareness to transfer. The authors contrasted the effectiveness of transfer plus SRL to the transfer treatment alone and to teacher-designed instruction. Twenty-four 3rd-grade teachers, with 395 students, were assigned randomly to conditions. Treatments were conducted for 16 weeks. Students were pre- and posttested on problem-solving tests and responded to a posttreatment questionnaire tapping self-regulation processes. SRL positively affected performance.

Reading difficulties as a cause of behavior problems in adolescence.

It is difficult to state whether the learning and reading problems cause the socially deviant behaviour, or whether the emotional problems lead to the reading and learning problems in adolescents of normal intelligence. This may be a difficult question to answer in general, but in a given specific case with proper assessment, it is not hard to decide which came first. It has been stated that no deviant child among exceptional children suffers more in the way of retaliatory and rejecting attitudes on the part of those around him than does the delinquent youngster. It has also been found that teachers and youth workers do not like to deal with a delinquent child. This is in fact a sad state of affairs because though these youngsters may be difficult and lack motivation however, they do possess the potential to become successful criminals or tax paying citizens of our Community of tomorrow. Very much depends upon the help provided during the difficult years of adolescence. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

The Relationship Between Working Memory and Mathematical Problem Solving in Children at Risk and Not at Risk for Serious Math Difficulties.

This study identified cognitive processes that underlie individual differences in working memory (WM) and mathematical problem-solution accuracy in elementary school children at risk and not at risk for serious math difficulties (SMD). A battery of tests was administered that assessed problem solving, achievement, and cognitive processing in children in first (N = 130), second (N = 92) and third grades (N = 131). The results were that (a) younger children and children at risk for SMD performed poorer on WM and problem-solving tasks, as well as measures of math calculation, reading, semantic processing, phonological processing, and inhibition, than older children and children not at risk for SMD and (b) WM predicted solution accuracy of word problems independent of measures of fluid intelligence, reading skill, math skill, knowledge of algorithms, phonological processing, semantic processing,'speed, shortterm memory, and inhibition. The results support the notion that the executive system is an important predictor of children's problem solving. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Enhancing Mathematical Problem Solving Among Third-Grade Students With Schema-Based Instruction.

The purposes of this study were to assess the effects of schema-based instruction (SBI) in promoting mathematical problem solving and to investigate schema induction as a mechanism in the development of mathematical problem solving. Twenty-four 3rd-grade teachers, with 366 students, were assigned randomly to conditions that provided instruction on 4 types of word problems. The 3 16-week conditions were contrast, SBI, and SBI with practice in sorting word problems into schemas. Students were pre- and posttested on mathematical problem-solving tests and were posttested on schema development. Students receiving SBI, with and without sorting practice, improved more than the contrast group on problem-solving measures. Concurrently, the SBI groups' schema development exceeded that of the contrast group, and schema development explained a substantial portion of unique variance in students' posttreatment problem-solving performance. Results also suggested the need for additional research testing the contribution of practice in sorting word problems. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

School readiness among children with varying histories of language difficulties.

This study tested the hypotheses that (a) persistent language difficulties during childhood would predict lower school readiness and (b) language difficulties present just prior to school entry would predict lower school readiness beyond any effects of persistence. The study involved examining indicators of school readiness collected at kindergarten for children exhibiting various histories of language ability based on language measures collected at 15, 24, 36, and 54 months by the National Institute of Child Health and Human Development's Early Child Care Research Network. Children (N = 1,064) were classified according to whether they exhibited expressive or receptive language difficulties at each time point measured. The relation between persistence and timing of these difficulties to each kindergarten outcome was studied through a common factor approach for categorical outcomes. Persistence of language difficulties was not generally related to kindergarten outcomes. However, a robust effect was found for timing of language difficulties: Children who exhibited language difficulties at 54 months exhibited significantly depressed performance on measures of school readiness. Findings are discussed in terms of current policy and research concerning kindergarten readiness for children exhibiting risk. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Group problem solving under two types of executive structure.

Speed of problem solving by 4-man teams of airmen was measured for 2 conditions of group organization: (a) with responsibility centered in 1 team member, and (b) with responsibility shared equally by all members. Problems in algebraic form required Ss to acquire environmental state information and to adjust the settings of certain response switches. The 2 conditions of group structure and 2 types of problems were varied factorially. Analysis of variance indicates (a) that problems requiring reaction to environmental changes are more quickly solved under the shared responsibility condition, and (b) that problems involving coordination of action among operators are more efficiently solved with a competent centralized authority. Designation of a low aptitude group member as leader produced inferior performance on both problem types. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Mathematical concept formation in children.

The issues are discussed under 4 major headings: (1) all-or-none conditioning processes in simple concept formation, (2) some results concerning transfer, (3) geometric invariants of perceptual space, and (4) mechanisms of concept formation. Experiments were developed to probe "the limits of mathematics learning in the classroom for elementary school children of various ages… . The search for a detailed algebra of concepts to provide explicit and definite mechanisms for generating new concepts out of old ones may in many situations, perhaps particularly with children, be a mistaken venture. With the exception of a few salient features, new concepts may be formed by random choices, and only after 1 or more instances of the concept have been reached or put together by accident or chance is the new concept recognized."

Filial therapy with parents of children experiencing learning difficulties.

The purpose of this study was to determine the effectiveness of a 10 week filial therapy training model as an intervention method for parents of children with learning difficulties. Results of the analysis of covariance revealed that the parents in the experimental group scored significantly higher after training than the parents in the control group on their attitude of acceptance of the child. The experimental group parents attained a significantly lower mean total score on level of stress related to parenting than the control group parents. There was no significant difference between the experimental and control groups' posttest mean scores on the total behavior problems.

Reading difficulties in children: Proceedings of a conference held in Douglas Hospital, Montreal, Quebec, November, 1967.

Presents the proceedings of a conference on reading difficulties in children, which was held in Douglas Hospital Montreal, Quebec in November 1967. With the development of interest in cognitive processes in recent years, special education gained a distinct role in psychotherapy with children. This conference was a natural outcome of a therapeutic-educational program whereby considerations of the patient's progress and future moved from conceptions of classical psycho-pathology to conceptions of an educational-methodological nature. The conference was organized, not with the purpose of becoming a "cure-all" event, but as an initial step towards achievement of functional cooperation between professionals in an important field of child development and childhood psychopathology.

Instruction by mothers and fathers during problem solving with their young children.

Mothers and fathers of 163 5-year-olds were observed interacting with their children in dyads on 2 separate occasions on a familiar and unfamiliar cognitive activity. Within- and between-family comparisons were conducted. Few differences in the instruction provided by mothers and fathers appeared, and those that did were on the unfamiliar task. On this task, instruction by mothers, within and across families, was more responsive to children's changing skill than was instruction by fathers. Directive and disapproving comments by parents were related to poorer posttest performance by the child. High level of instruction by both parents was related to better posttest performance than was low level of instruction by parents. Contributions of parents to their children's cognitive development are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

The effects of technical difficulties on learning and attrition during online training.

Although online instruction has many potential benefits, technical difficulties are one drawback to the increased use of this medium. A repeated measures design was used to examine the effect that technical difficulties have on learning and attrition from voluntary online training. Adult learners (N = 530) were recruited online and volunteered to participate in a 4-hr training program on using computer spreadsheets. Technical difficulties were inserted in some of the training modules in the form of error messages. Using multilevel modeling, the results indicated that the presence of these technical difficulties impaired learning, such that test scores were lower in modules where trainees encountered technical difficulties than in modules where they did not encounter technical difficulties. Furthermore, the effect on learning was greater among trainees who eventually withdrew from the course than among trainees who completed the course. With regards to attrition, pretraining motivation provided a buffer against dropping out, especially when trainees encountered technical difficulties. Learning also predicted attrition from the subsequent module, such that attrition was higher among trainees with low test scores in the previous module. The current study disentangles some of the implications of technical difficulties and suggests that organizations should provide trainees with the technical support required to overcome technical difficulties in training. Furthermore, the findings contribute to our theoretical understanding of the implications of interruptions on performance in online training.

Code-oriented instruction for kindergarten students at risk for reading difficulties: A randomized field trial with paraeducator implementers.

The purpose of this study was to evaluate the effectiveness of code-oriented supplemental instruction for kindergarten students at risk for reading difficulties. Paraeducators were trained to provide 18 weeks of explicit instruction in phonemic skills and the alphabetic code. Students identified by their teachers meeting study eligibility criteria were randomly assigned to 2 groups: individual supplemental instruction and control. Students were pretested in December, midtested, and posttested in May-June of kindergarten. At posttest, treatment students significantly outperformed controls on measures of reading accuracy, reading efficiency, oral reading fluency, and developmental spelling. Treatment students had significantly higher linear growth rates in phonemic awareness and alphabetic knowledge during the kindergarten treatment. At a 1-year follow-up, significant group differences remained in reading accuracy and efficiency. Ethical challenges of longitudinal intervention research are discussed. Findings have policy implications for making supplemental instruction in critical early reading skills available. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Growth in working memory and mathematical problem solving in children at risk and not at risk for serious math difficulties.

The influence of cognitive growth in working memory (WM) on mathematical problem solution accuracy was examined in elementary school children (N = 353) at risk and not at risk for serious math problem solving difficulties. A battery of tests was administered that assessed problem solving, achievement, and cognitive processing (WM, inhibition, naming speed, phonological coding) in children in 1st, 2nd, and 3rd grade across 3 testing waves. The results were that (a) children identified as at risk for serious math problem solving difficulties in Wave 1 showed less growth rate and lower levels of performance on cognitive measures than did children not at risk; (b) fluid intelligence and 2 components of WM (central executive, visual-spatial sketchpad) in Wave 1 (Year 1) predicted Wave 3 word problem solving solution accuracy; and (c) growth in the central executive and phonological storage component of WM was related to growth in solution accuracy. The results support the notion that growth in WM is an important predictor of children's problem solving beyond the contribution of reading, calculation skills, and individual differences in phonological processing, inhibition, and processing speed.

Dysfluent reading in the absence of spelling difficulties: A specific disability in regular orthographies.

Two large studies identified substantial numbers of German-speaking children (Grade 3) with marked dissociations between reading and spelling difficulties. These dissociations were expected because German exhibits high regularity in the direction of graphemes to phonemes (forward regularity) but not in the direction of phonemes to graphemes (backward regularity). High forward regularity allows reliance on phonological processing in reading (even in advanced fluent reading), whereas low backward regularity requires reliance on orthographic memory representations in spelling. Dysfluent reading in the absence of spelling difficulties was associated only with a naming speed deficit--assessed at school entrance--but not with phonological memory or phonological awareness deficits. In contrast, a specific spelling deficit was preceded by phonological deficits. (PsycINFO Database Record (c) 2010 APA, all rights reserved)
