Do children with mathematics learning disability in Hong Kong perceive word problems differently?

The current study aimed at identifying the difficulties experienced by children with mathematics learning disability (MLD) in the problem representation phase of arithmetic word problem solving using a novel problem types identification task. An MLD group (n = 66) and a typically achieving control group (n = 139) were recruited for an assessment on problem type identification as well as some domain-general and mathematics-related cognitive abilities. Results from ANCOVA showed that the MLD group scored significantly lower than the typically achieving control group on this assessment, after controlling for the effect of cognitive correlates, reading achievement and arithmetic performance. Furthermore, this assessment significantly predicted MLD membership even after taking children's arithmetic competency into account. The current study confirmed the difficulties in problem representation of arithmetic word problems experienced by students with MLD and provided evidence for the need to introduce schema instructions in mathematics classes.     

Impulse control or selective attention: Remedial programs for hyperactivity

The purpose of the present study was to compare various cognitive treatment approaches for ameliorating the difficulties of hyperactive children on tasks requiring sustained vigilance and accuracy. Differential training techniques comparing training in attention to inhibitory control indicated that a combination of attentional and inhibitory control strategies was most efficacious in enhancing cognitive performance of these children. The findings from the present research further were interpreted to support the hypothesis suggesting that problems with impulse control and attention occur concurrently in hyperkinetic children, although remediation in attentional deploying strategies is necessary for enhancing cognitive performance of these children. The results from this study further indicated that training hyperkinetic children solely in inhibitory control simply is not sufficient for enhancing cognitive performance.     

Effectiveness of Parent–Child Number Board Game Playing in Promoting Chinese Kindergarteners’ Numeracy Skills and Mathematics Interest

Research Findings: In Study 1, we observed 32 Chinese kindergarteners playing a number board game with their caregivers in dyads. Number board game playing provided important opportunities for kindergarteners and their caregivers to talk about an array of number concepts, but their numeracy-related exchanges rarely went beyond counting. In Study 2, 88 Chinese kindergarteners and their parents were randomly assigned to 1 of 4 groups, namely, the game with parent training group, the game without parent training group, the exercise book group, and the control group. After a 4-week intervention, kindergarteners in the 3 treatment groups who began as relatively unskilled in numeracy showed comparable improvement in 3 numeracy tasks, and the effect sizes were often larger in the game with parent training group than in the game without parent training group. Moreover, kindergarteners in the 2 game groups tended to show relatively heightened mathematics interest. Practice or Policy: Findings of these 2 studies suggest that number board game playing has the potential benefit of promoting kindergarteners’ numeracy competence and mathematics interest. Training of parents might even optimize kindergarten children’s gains from parent–child number board game playing.     

Effectiveness of visual and verbal prompts in training visuospatial processing skills in school age children

Recent decades have witnessed a growing interest in intervention-based assessment to promote and enhance children’s learning. In this study, we explored the potential effect of an experimental visual–spatial intervention procedure and possible training benefits of two prompting modalities: one group received training with verbal and visual prompts, a second group training with visual prompts only, while a third, control group did not receive any training. The two training methods led to significant improvements of performance in visuospatial tasks as compared to control group, and they did so about equally well. Our findings provide evidence for the efficiency and benefits of interventions targeting visuospatial processing skills. The success of such interventions does not seem to be bounded by age or gender, and it seems that visual cues are particularly effective.     

Relations Between Children's Invented Spelling and the Development of Phonological Awareness

The objective of this study was to assess the impact on phonological skills of a training program that was intended to lead preschool children to move from prephonetic spellings to early phonemic spellings. The participants were 30 preschool children who were divided into two groups (experimental and control groups) that were equivalent in terms of the children's intelligence, the number of letters with which they were familiar and the nature of their invented spelling. The intervention proved effective, inasmuch as the children in the experimental group moved to early phonemic spellings, whereas those in the control group did not. This conceptual evolution entailed enhanced performance in phonemic classification, segmentation and deletion tests, in which the children in the experimental group displayed a degree of progress which differed significantly from that achieved by the members of the control group.     

An intervention approach for children with teacher- and parent-identified attentional difficulties

Using a multimodal and multi-informant method for diagnosis, we selected 33 children by teacher and parent nomination for attention and work completion problems that met DSM-IV criteria for attention-deficit/hyperactivity disorder (ADHD). Of the 33 children in this group, 21 participated in the initial intervention, and 12 were placed in an ADHD control group and received the intervention after pre- and posttesting. A similarly selected group of 21 children without difficulties in attention and work completion served as a control group. Each child was assessed on pre- and posttest measures of visual and auditory attention. After an 18-week intervention period that included attention and problem-solving training, all children in the intervention and control groups were retested on visual and auditory tasks. Children in both ADHD groups showed significantly poorer initial performance on the visual attention task. Whereas the ADHD intervention group showed commensurate performance to the nondisabled control group after training, the ADHD control group did not show significant improvement over the same period. Auditory attention was poorer compared to the control group for both ADHD groups initially and improved only for the ADHD intervention group. These findings are discussed as a possible intervention for children with difficulties in strategy selection in a classroom setting.     

Kindergarten prevention of dyslexia: does training in phonological awareness work for everybody?

This study examined the effects of training in phonological awareness on kindergarten children. Comparisons of children at risk (i.e., children with initially low levels of metalinguistic ability) with initially average and advanced children revealed that training gains were similar for all of these groups. Furthermore, training had comparable long-term effects on reading and spelling in Grades 1 and 2 for each group. In fact, the trained children at risk showed better reading and spelling performance than a randomly selected control group. Although considerable individual differences in training effectiveness were found Within the group of at-risk children, there was clear evidence that the training program substantially reduced the risk of becoming dyslexic in school.     

TEACHING INDUCTIVE THINKING TO HIGHLY ABLE CHILDREN

Two criteria were used to identify highly able kindergarten children: assessment by teachers and an IQ ≥ 115 on Raven's Progressive Matrices. In this way, 16 highly able children were found, matched pairwise according to age and IQ, and then randomly allotted to two treatment conditions. In one condition the children were trained using a program for fostering inductive thinking, whereas the children in the other condition continued their normal kindergarten activities. Based upon a new theory of inductive reasoning, the training was expected to have a positive effect on intelligence test performance. Results showed that all of the trained children outperformed their matched counterparts. It was concluded that, even with highly able children, the level of cognitive functioning can be improved, and that training of inductive thinking is an effective means to this end.     

Researching and promoting phonological awareness in the nursery class

The paper summarises the pilot study and the first two phases of a longitudinal study which set out to prevent the emergence of written language difficulties, by addressing the ability of pre-schoolers to make phonological judgements. It describes the assessment procedure which was used with 240 nursery-class children, aged 4 years 5 months, and the activities which were designed to give these children experience in attending to the sound structure of language before the assessment was carried out. Following assessment 41 children were identified as having poor rhyme awareness and were targeted for one-to-one training. In the second phase of the study, also discussed here, 21 were given training in the skills supporting phonological awareness and the remainder were assigned to a control group for equivalent training in categorisation skills. It is intended that the literacy skills of both groups will be assessed when the children are 7 years old.     

Phonological abilities and writing among portuguese preschool children

The objective of this study was to identify causal relationships between the development of phonological abilities and progress in writing in preschool children. The participants were 44 children, with an average age of 5 years and 6 months, and whose writing was syllabic with phonetization. The children were divided into three groups. They were subjected to a pre-test and a post-test that were intended to evaluate both their writing and their phonological skills. In between the two tests experimental group 1 underwent a writing training program designed to lead them to produce syllabic-alphabetic/alphabetic writing, while experimental group 2 was subjected to a phonological training program designed to work on phonetic units. The third group served as a control group. The number of letters known and the level of intelligence were controlled. The children in the two experimental groups achieved results that revealed a similar degree of progress (greater than the control group) in both their writing and their phonological abilities.     

The effects of social skills training and peer involvement on the social adjustment of preadolescents

This study examined the effects of social skills training and peer involvement on the peer acceptance of disliked preadolescents. 56 fifth- and sixth-grade children were identified as unaccepted by their peers and deficient in conversational skills. These children were then randomly assigned to 1 of 4 treatment conditions: (1) conversational skills training (individual coaching), (2) peer involvement under superordinate goals (group experience), (3) conversational skills training combined with peer involvement (group experience with coaching), and (4) a no-treatment control. Differential treatment effects were observed at both a posttreatment and follow-up assessment. As predicted, conversational skills training promoted skill acquisition and increased skillful social interaction. Peer involvement increased peer acceptance and children's self-perceptions of their social efficacy. The results were interpreted in terms of a developmentally based multidimensional model of social competence.     

A close look at the efficacy of Fast ForWord Language for children with academic weaknesses

This study evaluated the efficacy of the computer-assisted intervention program known as Fast ForWord Language in a sample of children in grades 1 through 6 referred for poor academic performance. Fast ForWord Language combines intensive training in multiple receptive language skills with adaptive acoustic waveform lengthening and amplification to remediate deficits in auditory temporal processing that are purported to be the root cause of developmental language disorders and many reading disabilities. Students in the treatment group were matched with students in a no-contact control group and all were assessed in four domains before and immediately after the 4–8 week intervention: (a) oral language competency; (b) phonological processing abilities; (c) basic reading skills; and (d) classroom behavior. Except for performance on a measure of expressive oral language, on which children in the treatment group achieved significantly greater gains than those in the control group, changes in test scores from pretest to posttest were equivalent for the two groups. However, when the lowest performing students in each group were compared, the children in the treatment group demonstrated superior gains in expressive oral language, syllable and sound blending, and reduction in problem behaviors. Thus, Fast ForWord Language had a positive, albeit limited impact on the oral language skills, academic performance, and social behaviors of some children in this study. However, due to methodological weaknesses and limited treatment fidelity, the study results must be interpreted cautiously.

Group-based intervention on attention and executive functions in the school context

The objective of the study was to examine the effects of a group-based behavioural, cognitive and skills training intervention (Maltti) provided in schools for elementary school pupils with attention and executive function (EF) deficits. The treatment effects were identified by comparing an intervention group (n = 46) with a waitlist control group (n = 26). Specific effects of the intervention on behavioural deficits in attention and EF in a classroom setting as well as on academic skills were examined. Our analysis indicated that significant intervention effects could be found in the behavioural manifestation of attentional and executive skills in the classroom setting among children (n = 30) who were evaluated as having moderate symptoms in the pre-intervention assessment. Positive effects of the intervention were also observed in arithmetic and reading skills. The severity level of pre-intervention attention and EF deficits did not moderate the results observed in the academic skills tests. The results of this study suggest that a combination of behavioural, cognitive and skills training methods applied in a school context can be effective in reducing attention and EF problems and enhancing the academic performance of children with attention and EF deficits.     

The role of cognitive flexibility in young children’s potential for learning under dynamic testing conditions

The aim of the current study was to investigate to what extent children’s potential for learning is related to their level of cognitive flexibility. Potential for learning was measured through a dynamic testing procedure that aimed to measure how much a child can profit from a training procedure integrated into the testing process, including the amount and type of feedback the children required during this training procedure. The study followed a pre-test–training–post-test control group design. Participants were 153 6–7-year-old children. Half of this group of children were provided with a standardised graduated prompts procedure. The other half of the participants performed a non-inductive cognitive task. Children’s cognitive flexibility was measured through a card sorting test and a test of verbal fluency. Results show that cognitive flexibility was positively related to children’s performance, but only for children in the practice-only condition who received no training. These outcomes suggest that dynamic testing, and more in particular, the graduated prompting procedure, supports children’s cognitive flexibility, thereby giving children with weaker flexibility the opportunity to show more of their cognitive potential as measured through inductive reasoning.

     

The effect of dynamic assessment based instruction on Children’s Learning

The purpose of this study is to demonstrate that dynamic assessment based instruction increases children’s learning by using a quasi-experimental research design in Korea. In this study, dynamic assessment is defined as a measurement method of the zone of proximal development (ZPD) as well as the qualitative and quantitative diagnostic information for individual children. In addition, dynamic assessment based instruction is defined as a teaching method using the diagnostic information types in order to increase children’s learning. In this study, 59 children between the ages of 4 and 5 participated. Three types of number concept achievement tests (pre-test, parallel test, and post-test) for each age group were developed and the content validity, face validity, and split-half reliability were examined. After conducting the pre-test, the children of each age group were divided into an experimental group and a control group. Dynamic assessment based instruction regarding number concepts was undertaken only with the experimental group for 4 weeks. Both groups took a post-test after completing the 4 weeks of classes. The ANCOVA technique wa ls used for data analysis. The result of this study shows that dynamic assessment based instruction has a significant effect on children’s learning of number concepts (in the case of 4-year-old children, F = 12.34, p<0.01; 5-year-old children, F = 20.03, P<0.01). Therefore, dynamic assessment based instruction should be used widely for children’s cognitive learning.     

The effects of training on the development of the ability to control variables

Based on a criterion test 27 fifth and sixth grade students were selected who could not control variables. Three groups were formed. The control group received no training; a second group received training relying upon external reinforcement, and the third group, training designed to induce internal cognitive conflict. The groups receiving training did only slightly better than the control group on the posttest. On the retention test one month later, all three groups had almost identical scores. The mean combined retention test score was found to be significantly greater than the pretest score. The improvement of the control and conflict groups supports Smedslund's⁸ finding that external reinforcement may not always be necessary for behavioral changes to occur. A further analysis of test scores led to the classification of students according to Piaget's developmental stages. During the course of the study a significant number of students improved in their stage placement. Based on retention test performance nearly half of the students having a mean age 11.8 years could be classed in late formal operations with regard to their ability to control variables. Inhelder and Piaget¹² reported that this level was not normally reached until 14 or 15 years of age. In conclusion, the results support the possibility that while development of the ability to control variables can be accelerated by training at the fifth and sixth grade level some children are surprisingly unaffected regardless of whether the training is based on external reinforcement or cognitive conflict procedures.     

Avoiding repetitions reduces ADHD children's management problems in the classroom

Abstract

Students with attention-deficit hyperactivity disorder (ADHD) often exhibit non-compliance that presents a significant management problem for classroom teachers. Student behavior management training programs suggest that reducing repetitions of commands improves student compliance. To examine this claim, 86 teachers of ADHD students between the ages of 5 and 10 were randomized into treatment and control groups. Barkley's procedure for reducing repetitions was administered in the treatment group. Repeated-measures ANOVA revealed that children in the treatment group exhibited a significant reduction in non-compliance (p> 0.002), while children in the control group did not. These results suggest that Barkley's technique is effective and should be recommended to teachers of ADHD children.     

The Effect on Reasoning,Reading and Number Performance of Computer‐presented Critical Thinking Activities in Five‐year‐old Children

Summary The performance of 64 five‐year‐old children on Raven's Coloured Progressive Matrices, the Break‐through to Literacy Reading Scheme, and a test of mathematics was noted, and the children were designated as high or low initial performance on each by division at the medians. They were then randomly divided within sexes into two groups. A treatment group worked, over a 13 week period, through 32 computer presented problem‐solving activities while a control group did alternative activities. All the children were then re‐tested. The results showed a significantly greater improvement between the pre‐ and post‐test for the treatment group than for the control group on Raven's Matrices for both high and low initial performance. For reading the low initial attainment treatment subjects improved significantly more than the control. In mathematics there was no significant effect of the treatment. The results were discussed in terms of the skills underlying reading and number work.     

Exploring effects of an early math intervention: The importance of parent–child interaction

We explore whether training parents' math skills or playing number games improves children's mathematical skills. Participants were 162 parent–child dyads; 88.3% were white and children (79 female) were 4 years (M = 46.88 months). Dyads were assigned to a number game, shape game, parent-only approximate number system training, parent-only general trivia, or a no-training control condition and asked to play twice weekly for 8 weeks. Children in the number game condition gained over 15% SD on an assessment of mathematical skill than did those in the no-training control. After 8 additional weeks without training, effects diminished; however, children of parents in the ANS condition underperformed those in the no-treatment control, which was partially explained by changes in the home numeracy environment.
