This study investigated whether children's inversion shortcut use (i.e., reasoning that no calculations are required for the problem 4 × 8 ÷ 8, as the answer is the first number) is related to their analogical reasoning ability, short-term memory capacity, and working memory capacity. Children from Grades 6 and 8 solved multiplication and division inversion problems and classical analogy word problems and completed memory tasks. Analogical reasoning ability and working memory functioning both accounted for individual variance in inversion shortcut use. These findings suggest that the ability to understand relationships and executive functioning may enable children to internally represent and manipulate mathematical problems, facilitating the application of conceptual mathematical knowledge to generate the inversion shortcut.  相似文献

This study used a large-scale cluster randomized longitudinal experiment (N = 719; 35 schools) to investigate the effects of online mathematics mini-games on primary school students’ multiplicative reasoning ability. The experiment included four conditions: playing at school, integrated in a lesson (Eschool), playing at home without attention at school (Ehome), playing at home with debriefing at school (Ehome-school) and, in the control group, playing at school mini-games on other mathematics topics (C). The mini-games were played in Grade 2 and Grade 3 (32 mini-games in total). Using tests at the end of each grade, effects on three aspects of multiplicative reasoning ability were measured: knowledge of multiplicative number facts, skills in multiplicative operations, and insight in multiplicative number relations and properties of multiplicative operations. Through path analyses it was found that the mini-games were most effective in the Ehome-school condition, where both students’ skills and their insight were positively affected as compared to the control group (significant ds ranging from 0.22 to 0.29). In the Eschool condition, an effect was only found for insight in Grade 2 (d = 0.35), while in the Ehome condition no significant effects were found. Students’ gameplay behavior (time and effort put in the games) was in some cases, but not always, related to their learning outcomes.  相似文献

The effects of intervention for peer mediation and mother-child mediated learning experience (MLE) strategies on children’s MLE strategies and cognitive modifiability (CM) was investigated on a sample of 100 mother–child dyads. CM was examined in domains of executive functions and analogical reasoning. The MLE interactions were analyzed by Observation for Mediated Interaction (OMI) scale. Children of high- and low-mediating mothers were assigned to experimental (n = 49) and control (n = 51) conditions. The experimental group received a peer-mediation program and the control groups received an alternative creativity program. The children (in Grade 3) were assigned as mediators of learners (in Grade 1) and taught them analogical reasoning problems. The peer interaction was videotaped and analyzed by the OMI. All children were given dynamic assessment after the interaction. Children in the experimental group showed higher MLE strategies and CM than did children in the control condition. Mediators of low-MLE mothers in the experimental group showed greater CM than did mediators in the control group. Structural equation modeling analysis showed that mediators’ cognitive modifiability was explained by proximal factors of treatment, mothers’ quality of mediation (QM) and mediators’ QM; learners’ cognitive modifiability was explained by mediators’ QM. The findings were discussed in relation to the MLE theory and earlier findings.  相似文献

Alphabet books as studied in this research typically highlight one letter per page combined with a depiction of a word that begins with the letter (e.g., a bear illustrates B). This study tests whether children’s letter knowledge improves as a result of alphabet book sharing and how the visual processing of pictures and letters affects learning from repeated alphabet book readings. The study is designed as a randomized control trial in which participants were assigned to one of two experimental groups (N = 30) or a control group (N = 15). Half of the experimental group received version A in which the letters A–L were illustrated with anthropomorphic figures and the letters M–Z with objects. Half received version B in which the letters A–L were illustrated with objects and the letters M–Z with anthropomorphic figures. Mean age of the children was 57.6 months (SD = 3.6). While sharing the alphabet book we registered children’s eye movements in the first and fourth (last) reading session. Alphabet book reading stimulated letter knowledge although the make-up of the alphabet book moderated the effects. Relatively more visual attention to pictures of anthropomorphic figures interfered with learning letters from alphabet book sharing. Visual attention to letters also predicted letter knowledge and learning. Only a small part of each letter attracted children’s attention and the briefer their fixations on this distinctive area, the more letters they knew at the pretest and were able to learn from alphabet book sharing.  相似文献

ObjectiveThough children exposed to familial violence are reported to have difficulties with a range of emotional and behavioral problems (e.g., lower school achievement) that implicate executive function (EF) deficits, relatively little research has specifically examined EF as a function of trauma exposure in children.MethodsBased on parent report of children's exposure to potentially traumatic events, children (N = 110; AgeMean = 10.39) from an ethnically diverse community sample were compared across three trauma-exposure groups: familial trauma, non-familial trauma, and no trauma. Children completed a battery of tests to assess working memory, behavioral inhibition, processing speed, auditory attention, and interference control.ResultsFamilial trauma (relative to non-familial and no trauma exposure) was associated with poorer performance on an EF composite (composed of working memory, inhibition, auditory attention, and processing speed tasks); the effect size was medium. Both trauma-exposure status and dissociation symptoms explained unique variance in EF performance after controlling for anxiety symptoms, socio-economic status, and potential traumatic brain injury. While IQ and EF performance were related, SES predicted unique variance in IQ (and not EF) scores, while familial-trauma exposure did not.ConclusionsThe contribution of trauma exposure to basic executive functioning held after taking into account symptoms (anxiety and dissociation), socio-economic status, and possible traumatic brain injury exposure. EF problems may provide one route via which maltreated children become at risk for peer, academic, and behavior problems relative to their peers.Practice implicationsEF problems may provide one route via which maltreated children become at risk for peer, academic, psychological, and behavior problems relative to their peers. Recently, intervention strategies have emerged in the anxiety and mood disorder treatment literatures that appear to effectively target EFs. As future research continues to specify the relationship between child trauma exposure and EF performance, these innovative treatments may have important practice implications for addressing EF deficits.  相似文献

The hereditary basis of dyslexia makes it possible to identify children at risk early on. Pre-reading children genetically at risk received during 14 weeks a home- and computer-based training in phonemic awareness and letter–sound relationships in the context of reading instruction. At posttest training effects were found for both phonemic awareness and letter knowledge. Trained at-risk children (n = 31) made more progress than untrained at-risk controls (n = 26) and kept up with untrained not-at-risk controls (n = 16). However, the headstart of the trained group did not affect beneficially first and second grade reading and spelling proficiency. Following the start of phonics-based instruction at school, the trained at-risk children could not be discriminated from the untrained at-risk controls, and they were delayed relative to the not-at-risk controls. In order to promote long-term benefits and prevent undoing the advantage of early intervention, delivery should be both home- and school-based and more effort needs to be put in throughout first grade.  相似文献

Arithmetic word problems are often presented accompanied by illustrations. The present study examined how different types of illustrations influence the speed and accuracy of performance of both good (n = 67) and poor arithmeticians (n = 63). Twenty-four arithmetic word problems were presented with four types of illustrations with increasing information value. The results show that illustrations can have a detrimental effect on performance on arithmetic word problems, produced by irrelevant, redundant or interacting sources of information. Principles from cognitive load theory are used to explain the results, in particular in relation to (poor) working memory ability.  相似文献

In this study we examined the effectiveness of Tekster [Texter], a comprehensive program for writing for the upper elementary grades, combining strategy instruction, text structure instruction, and the teaching of self-regulation skills with observational learning, explicit instruction, and (guided) practice to address both the focus of instruction (what is taught) and the mode of instruction (how it is taught). Further, we investigated the added value of a professional development program for teachers on the effectiveness and implementation of the intervention in the classroom, by adopting a teachers-training-teachers approach. One group of teachers (N = 31) was trained by experts, and subsequently trained their colleagues (N = 37). Quasi-experimental results showed that students’ writing performance improved after the intervention (ES = 0.55), while generalizing over tasks, students, and teachers. Further, teachers became more positive and felt more efficacious about teaching writing after the intervention. There were no differences between trainers and trainees, which provides evidence for the spillover effect of professional development. To get more insight in how teachers implemented the intervention in their classroom and in the social validity of the intervention and the teachers-training-teachers approach, we triangulated post-intervention questionnaires with classroom observations and interviews. This mixed methods approach revealed that both trainers and trainees were highly satisfied with the program and easily adapted their focus of instruction. However, for adjusting the mode of instruction more teacher support seems to be needed.  相似文献

This study compares transfer performed by subjects trained to solve verbal analogies, with transfer by subjects trained to construct them. The first group (n = 57) received instruction in a strategy to solve verbal analogies and the second group (n = 66) was trained in strategies for constructing such analogies.Before and after intervention, all subjects received three analogical tasks: verbal, figural and numerical. The success rate was measured by an effectiveness measure. Even though both interventions improved performance, the construction group scored higher results in the numerical and figural analogy tasks. Following Sternberg's “componential sub-theory of intelligence”, the constructors' advantage is attributed primarily to higher-level activation of the three significant metacomponents: problem recognition, strategy planning and supervision in task performance.  相似文献

One-hundred-six 5-year-olds’ (Mage = 5;6; SD = 0.40) were trained with second-order false belief tasks in one of the following conditions: (a) feedback with explanation; (b) feedback without explanation; (c) no feedback; (d) active control. The results showed that there were significant improvements in children's scores from pretest to posttest in the three experimental conditions even when children's age, verbal abilities, or working memory scores were controlled for. The training effect was stable at a follow-up session 4 months after the pretest. Overall, our results suggest that 5-year-olds’ failures in second-order false belief tasks are due to lack of experience and that they can be helped over the threshold by exposure to many stories involving second-order false belief reasoning, including why questions.  相似文献

We studied the connection of IQ, reading disability (RD) and their interaction with reading, spelling and other cognitive skills in adolescents with average IQ and RD (n = 22), average IQ, non-RD (n = 71), below average IQ and RD (n = 29), and below average IQ non-RD (n = 33). IQ was not connected to reading and spelling in subjects without RD, but a connection to non-word spelling in subjects with RD existed. IQ and RD showed a connection to other cognitive skills (IQ to working memory, verbal memory and syntactic skills, RD to poor performance in text reading and rapid naming and both of them to reading comprehension, phonological and arithmetic skills), but no interaction existed. Our results are consistent with those of earlier studies showing that IQ does not play a significant role in the presentation of RD. However, adolescents with below average IQ and RD seemed to have much broader deficits in academically important skills such as arithmetic and reading comprehension than the other groups.  相似文献

Recent models of attention deficit/hyperactivity disorder (ADHD) suggest that the association between achievement motivation and school performance may be stronger in children with ADHD than in typically developing children. Therefore, the present study investigated associations between achievement motivation and performance on language skills and mathematical thinking in children with ADHD (n = 23; M = 9.4 years, SD = 1.1 years; 78% boys) and two matched control groups, i.e., a clinical control group (children with related disruptive behavior disorders; DBD), and a non-clinical control group (NC). Results confirmed stronger associations between achievement motivation and performance on receptive language and mathematical thinking in children with ADHD than in NC. Specifically, performance of children with ADHD was equal to NC for highly motivated ADHD children. These results underscore the importance of achievement motivation as a more essential key factor in the performance of children with ADHD as compared to typically developing children.  相似文献

Within a democratic and multicultural society, diversity is a reality, and differences between students are a fact which teachers have to deal with on a daily basis. Differentiated instruction aims to meet these differences in learning in order to provide all students with the best possible learning opportunities. However, to date no validated instruments exist to measure teachers’ perceptions of differentiated instruction and their related classroom practices. This study, therefore, examined the factor structure and reliability of the Differentiated Instruction Questionnaire, called the DI-Quest instrument. A list of 87 items was constructed, building on existing prevalent theoretical models of Differentiated Instruction (e.g. Tomlinson, 2014; Hall, 2002). An exploratory and confirmatory factor analysis was undertaken to investigate the factor structure of the questionnaire. As a result, five factors emerged: two factors related to the teachers’ philosophy of differentiated instruction (the teachers’ mindset and their ethical compass), two factors referred to the practical principles that teachers apply to differentiate (flexible grouping and output = input) and the last factor (differentiated instruction) covered the self-reported extent to which teachers differentiated their instruction related to three types of differences in learning (students’ interests, readiness and learning profile). As a result, the DI-Quest instrument entailed 31 items with a five-factor structure indicating a good fit (CFI = 0.919; TLI = 0.911; RMSEA = 0.041 [0.037–0.044 – 90% confidence interval, p(0.05) = 1.000]; SRMR = 0.048; χ2 = 5888.338, df = 465, p = 0.000). In addition, assuming theoretical relatedness between the factors, the validation of a DI-Quest model was empirically validated. We compared the model fit for two models by investigating which model had a lower BIC and AIC value and by comparing their chi square values. The best-fitting DI-Quest model showed four factors (teachers’ mindset, ethical compass, flexible grouping and output = input as dependent variables) functioning as significant predictors of the fifth factor (the self-reported adoption of Differentiated Instruction, which served as an independent variable). Moreover, this paper also discusses the psychometric properties of the DI-Quest instrument and the implications of the model for schools, educators and researchers.  相似文献

Maternal support has been conceptualized as a key factor in predicting children’s functioning following sexual abuse; however, empirical evidence for this assumption is rather limited. Prior studies may have failed to find a relationship between maternal support and children’s outcomes due to the methodological weaknesses of the prior literature such as the use of maternal support measures without adequately reported psychometric properties. Moreover, relatively few studies have investigated whether maternal support corresponds with children’s own self-reported symptoms. The aim of the present study was to utilize the only published measure of maternal support with sufficient psychometrics, the Maternal Self-Report Support Questionnaire (MSSQ; Smith et al., 2010), to determine if levels of pre-treatment support are associated with children’s self-reported trauma-related symptoms among 165 treatment-seeking children (M = 10.85, SD = 3.09) and their non-offending mothers. Levels of maternal emotional support corresponded with few of children’s outcomes, and when relationships were observed, emotional support was related to higher levels of symptoms. Maternal levels of blame and doubt were only associated with dissociative symptoms. Maternal support therefore appears to be an ineffective predictor of children’s post-disclosure trajectories and raises the possibility that maternal support is linked with poorer functioning.  相似文献

Two experiments examined visual attention distribution in learning from text and pictures. Participants watched a 16-step multimedia instruction on the formation of lightning. In Experiment 1 (N = 90) the instruction was system-paced (fast, medium, slow pace), while it was self-paced in Experiment 2 (N = 31). In both experiments the text modality was varied (written, spoken). During learning, the participants’ eye movements were recorded. Results from both experiments revealed that learners spent more time studying the visualizations with spoken text than those with written text. In written text conditions learners consistently started reading before alternating between text and visualization; moreover, they spent more time reading the text than inspecting the visualizations. While in Experiment 1 additional time that was made available in conditions with a slow or medium instruction pace was spent inspecting visualizations, in Experiment 2 longer learning times resulted from reading the text more intensively. With respect to learning outcomes (retention, transfer, and visual memory) Experiment 1 revealed an effect of text modality for visual memory only. In Experiment 2 no modality effects were found. Instruction pace was hardly related to learning outcomes. Overall, the results confirm prior findings suggesting that the distribution of visual attention in multimedia learning is largely guided by the text.  相似文献

Findings show that both positive and negative mood may hinder or promote information processing. In two experiments, we show that negative mood impairs transfer effects and learning. In the first experiment, N = 54 participants drawn from a training course for the Swiss Corps of Fortification Guards first learned to solve the three- and four-disk Tower of Hanoi (ToH) problem to mastery level. After mood induction, they were asked to solve one proximal (five-disk ToH) and two distal transfer tasks (the Missionary and Cannibal Problem and the Katona Card Problem). Participants in a negative mood solved the transfer tasks less efficiently. In the second experiment, this result was replicated with a sample of N = 80 participants drawn from a training course for nurses. Additionally, mood affected performance if it was induced before the learning phase; participants in a negative mood needed more repetitions to reach the mastery level and also performed worse in the transfer tasks, although there were no greater mood differences in this problem-solving phase. The implications for the design of learning settings are discussed.  相似文献

Although many children with reading difficulty (RD) are reported to struggle with mathematics, little research has empirically investigated whether this is the case for different types of RD. This study examined the mathematics skills of third graders with one of two types of RD: dyslexia (n = 18) or specific reading comprehension difficulty (n = 22), as contrasted to a comparison group (n = 247). Children's performance on arithmetic fact fluency, operations, and applied problems was assessed using standardized measures. The results indicated that children with dyslexia experienced particular difficulty with arithmetic fact fluency and operations: they were 5.60 times and 8.54 times more likely than other children to experience deficits in fact fluency and operations, respectively. Our findings related to arithmetic fact fluency were more consistent with domain-general explanations of the co-morbidity between RD and mathematics difficulty, whereas our findings related to operations were more consistent with domain-specific accounts.  相似文献

Maternal support is touted to play a critical role in predicting children’s symptom trajectories following sexual abuse disclosure. Yet, a recent meta-analysis indicates that this widely held belief may actually have limited empirical support. The lack of correspondence between maternal support and children’s symptoms may be the result of the limitations of the prior literature including the use of maternal support measures with inadequate psychometric properties. The aim of the present study was to utilize the only published measure with sufficient psychometrics properties, the Maternal Self-Report Support Questionnaire (MSSQ; Smith et al., 2010), to determine the relationships between maternal support and demographic and family characteristics, parent-reported children’s symptoms, and aspects of the traumatic event in a treatment-seeking sample. The sample included 252 treatment-seeking children (M = 8.86, SD = 3.85; 67.5% female, 59.5% White) and their mothers, who completed the MSSQ and other measures at pre-treatment. Mothers of older children, White children, and mothers with greater educational attainment reported higher levels of Emotional Support. Single mothers were more likely to report higher levels of Blame/Doubt than married mothers. Characteristics of the traumatic event, such as sexual abuse duration and number of sexual abuse incidents were negatively correlated with Emotional Support. Maternal support was related to relatively few of children’s symptoms and was not associated with levels of posttraumatic stress disorder (PTSD) symptoms. Although several demographic and family characteristics may be related to maternal support, it is a relatively weak predictor of children’s outcomes.  相似文献

In this study, we investigated the effects of teaching critical-thinking principles on university students’ epistemological beliefs, whether these effects had any relation to the teaching approaches, and whether there was any significant interaction effect between teaching approach and students’ epistemological beliefs. One hundred and eight undergraduates were randomly assigned to three different 65-min instructional interventions, namely, General, Infusion, and Immersion approaches. Statistical analyses of the data using a Repeated Measures ANOVA showed a statistically significant higher post-assessment performance, F (1, 105) = 19.769, p = .00. The main effect related to the intervention was also significant, F (2, 105) = 3.995, p = .021, but there was no significant interaction between intervention and epistemological beliefs. Post hoc comparisons revealed that students assigned to the Infusion strategy outperformed those assigned to the General approach on epistemological change.  相似文献

This study assessed the relationship between parental punishment and depression as well as quality of life in children with primary monosymptomatic nocturnal enuresis (PMNE). A consecutive sample of 65 children (7–13 years) with PMNE and 40 healthy children, selected as controls (Group III), were included in the study. The children with PMNE were further sub-classified into two groups: Group I, which included children who received parental punishment for enuresis and Group II, which comprised children who were not punished for bedwetting. Depression and health-related quality of life (HRQL) were assessed among the three groups. The number of wet nights per week was significantly increased in Group I compared with Group II (P < .001). In addition, the severity of depressive symptoms increased in Group I as compared to the other two groups (P < .001). Similarly, the psychosocial HRQL lower in Group compared to the control group (Group III) (P < .001). Prior parental discipline, including corporal punishment (B = 0.55, P = .008), as well as the frequency (B = 0.73, P < .001) and duration of punishment (B = 0.33, P = .02) were strong predictors of increased depressive symptom severity. It was also found that prior punishment (B = −0.42, P = .01) and the frequency (B = −0.62, P < .001) and duration of punishment (B = −0.34, P = .02) were strong predictors for poor psychosocial HRQL. Overall, parental punishment has a poor outcome in children with PMNE.  相似文献
