Both IQ and age related differences in the zones of proximal development of 89 four to eight year olds were investigated. Each child was asked to learn, transfer and generalize a strategy for solving the Tower of Hanoi puzzle. The speed, efficiency, accuracy and extent of support needed were analysed. Multivariate analyses of variance were performed on the data from each task. The benefits of high IQ were not as consistent as those of chronological age. They were most apparent in the learning and generalization tasks. Some high IQ children created challenges of their own in the unchallenging transfer task, or became bored. Two practical implications became apparent: the range of learning potentials in classes of children grouped by chronological age poses a formidable challenge for educators, and the learning of highly able children may detoriorate when they are offered the same curriculum as their peers.

High- and low-IQ children in the first, third, and fifth grades performed two free-recall tasks: a sort-recall task with sets of categorically related pictures, and a class-recall task, with children recalling the current members of their school class. All children were deemed to be experts concerning the composition of their school class, but, unlike experts in other domains, had no special motivation associated with their expertise. Recall and clustering on both tasks were high. The high-IQ children performed better than low-IQ children only on the sort-recall task. IQ was significantly correlated with measures of performance on the sort-recall task but not on the class-recall task. The results reflect the fact that the memory benefits associated with being an expert (here, elimination of IQ effects) are related to the greater knowledge the expert possesses and not to factors of motivation.  相似文献

In 5 studies, the learning and transfer abilities of 2-4-year-old children were examined on a task in which they were required to combine 2 separately learned solutions to reach a goal. The 3 main findings are very early competence on the task if it is situated in familiar settings, a developmental trend in the ability to notice the similarity across analogous versions of the problem that differ in surface format but share the same underlying logic, and the success of 2 forms of assistance in promoting transfer. Both emphasizing task similarity and encouraging the children to talk about the rules ensure that they will notice problem similarity and hence afford them the opportunity to apply the learned rules appropriately. Difficulties with noticing similarity, rather than in applying the rule, lead to transfer failure. Given a hospitable environment, children as young as 2-3 years of age can combine information and apply a reasoning rule quite broadly.  相似文献

Second- and fourth-grade children were classified according to their knowledge of soccer (experts vs. novices) and IQ (high vs. low), and given 2 sort-recall tasks. One task included items related to the game of soccer and the other included items from familiar natural language categories. Previous research has shown that expertise in a subject can compensate for low levels of performance on text comprehension tasks. Our results, the first examining the effects of both expertise and intelligence on a strategic memory task, were that soccer expert children recalled more items on the soccer list but not on the nonsoccer list than soccer novice children. However, soccer expertise did not modify a significant effect of IQ level, with high-IQ children recalling more than low-IQ children for all contrasts. Interest in soccer was found to be related to expertise but did not contribute to differences in memory performance. The results demonstrate that the knowledge base plays an important role in children's memory, but that domain knowledge cannot fully eliminate the effects of IQ on sort-recall tasks using domain-related materials. That is, although rich domain knowledge seemed to compensate for low aptitude, in that low-aptitude experts performed at the level of high-aptitude novices, its effects were not strong enough to eliminate performance differences between high- and low-aptitude soccer experts.  相似文献

Spontaneous transfer of learning is often difficult to elicit. This finding may be widespread partly because pretests proactively interfere with transfer. To test this hypothesis, 7-year-olds' transfer was examined across 2 numerical tasks (number line estimation and categorization) in which similar representational changes have been observed. As predicted, children given feedback on numerical estimates learned to use a linear representation of numerical quantity instead of a logarithmic one, but providing practice on a categorization pretest led children to continue using a logarithmic representation on the same task, which they otherwise abandoned with surprising frequency. These findings imply unsupervised practice of inappropriate representations impedes transfer, and studies of learning can greatly underestimate children's potential for transfer if pretest effects are uncontrolled.  相似文献

Studies on child development in cross‐cultural contexts generally contrast child‐rearing practices in traditional or non‐Western with those of Western societies. Thus, they show how non‐Western communities tend to emphasise the importance of interdependence and collectivism between family and group members; Western communities focus rather on the role of the individual and achievement within a competitive milieu. Similarly, close observation by younger siblings of older children and caregivers who ‘model’ tasks to be learned are usually concepts referring to non‐Western groups, whilst those detailing ‘scaffolding’ tend to focus on the caregiver/child dyad in the West. This paper questions the value of such binary divisions when studying the learning taking place in the homes of third‐generation migrants to the UK. Using examples of children, their younger siblings and their grandmothers in London, it shows ways in which the older generation skilfully syncretises traditional and Western teaching practices and how each child responds appropriately to the tasks in hand.  相似文献

Imagery deficits in nonverbal learning disabilities   总被引：6，自引：0，他引：6  
This study reports the observations gathered from 11 children referred to consulting services because of learning difficulties at school and diagnosed with nonverbal learning disabilities (NVLD). These children had an average verbal IQ, but a WISC-R performance IQ lower than the verbal IQ by at least 15 points and experienced difficulties especially in mathematics and drawing. The children completed a battery of four tasks requiring visuospatial working memory and visual imagery: a memory task composed of pictures and their positions (Pictures task), a task that required them to memorize the positions filled in a matrix (Passive Matrix task), a task that required them to imagine a pathway along a matrix (Active Matrix task) and a task that required them to learn groups made up of three words, using a visual interactive imagery strategy (TV task). In comparison to a control group of 49 children, children with NVLD scored lower in all the tasks, showing deficits in the use of visuospatial working memory and visual imagery. By contrasting subgroups of children of different ages in the control group, it was possible to show that some tasks did not show a clear developmental trend. Thus the deficits shown by the children with NVLD cannot simply be attributed to a developmental delay of these children, but seem to reflect a more severe disability.  相似文献

Children with dyslexia are believed to have very poor phonological skills for which they compensate, to some extent, through relatively well-developed knowledge of letter patterns. We tested this view in Study 1 by comparing 25 dyslexic children and 25 younger normal children, chosen so that both groups performed, on average, at a second-grade spelling level. Phonological skill was assessed using phoneme counting and nonword spelling tasks. Knowledge of legal and illegal letter patterns was tested using a spelling choice task. The dyslexic children and the younger nondyslexic children performed similarly on all the tasks, and they had difficulty, for the most part, with the same linguistic structures. Supporting the idea that older dyslexics spellings are quite similar to those of typical beginners, we found in Study 2 that experienced teachers could not differentiate between the two groups based on their spellings.  相似文献

This paper examines how and what teachers learn from their older and younger colleagues. Data were gathered from interviews and written reports from 27 Belgian and Finnish teachers. Thematic qualitative analysis was used. The results revealed differences in what teachers learn from older and younger colleagues. Teachers reported learning innovative teaching methods and ICT skills from younger colleagues, whereas practical information, classroom management skills, self-regulation and community building were learned mainly from older colleagues. Attitudes regarding teaching and different ways of being a teacher were learned from both younger and older colleagues alike. Similarities were also found in how teachers learned from their older and younger colleagues. Informal activities and relationships, different forms of mentoring, and working in subject teams or seminars were important sources of learning. An intergenerational learning perspective is important with respect to demographic changes in school staff and in preventing knowledge loss and teacher dropout.  相似文献

Adapting a modified reception paradigm, three bidimensional rules (conjunctive, disjunctive, conditional) and two instructional conditions (enforced attention vs standard rule learning) are used to test the assumption that deficient rule learning rather than inattention is responsible for poor learning with learning-disabled children. Main findings indicate learning-disabled children are deficient on binary conceptual rule tasks for three age groups (6 to 7, 8 to 9, 12 to 13) compared to normal children matched on sex and IQ regardless of experimental instructions. For both groups, learning is retarded by rule complexity while rate of learning diminishes with increasing age. Data reflect a truth-table logic at all ages for both groups, although there is evidence that disabled children perseverate with a rule-learning hypothesis characteristic of younger nondisabled children. Results are consistent with the hypothesis that rule learning is deficient in children with learning disabilities.  相似文献

The aim of the study was to investigate the effects of support on knowledge acquisition of gifted learners and their flow and mood during inquiry learning. Sixty-four gifted primary school children were randomly assigned to one of three conditions differing in support given in an inquiry task. Results showed that learners who were allowed to experiment themselves learned more, experienced more flow, and felt more positive toward the task than those who were not given this opportunity, but only when they were guided through the inquiry cycle by prompts to generate hypotheses, perform experiments, and draw conclusions. The overall conclusion is that gifted children benefit more from open, complex tasks when their learning process is externally regulated.  相似文献

Two experiments explored rates for introducing grapheme-phoneme correspondences (GPCs) and the types of correspondences taught for optimal alphabet and early literacy skills learning. In both studies, children entered with minimal alphabet knowledge and were randomly assigned within classrooms to one of two treatments delivered individually over 5 weeks. In Study 1, children grades K-1 were assigned to instruction in a set of either 10 (Slow rate, n?=?33) or 15 (Fast rate, n?=?32) single- and two-letter GPCs. Study 1 findings indicated that children who learned five added GPCs did not reduce learning of the common set of 10 learned GPCs for any measure (including letter names, sounds, letter sound writing, word reading, and spelling), and learning favored Fast items over Slow for letter sounds, letter sound writing, and word reading (median d?=?0.30). In Study 2, kindergarteners were assigned to instruction in either single letters only (Single, n?=?30) or mixed-size GPCs (Mixed, n?=?31). Instruction included application of GPCs to decoding and spelling. Results showed that kindergarteners in the Mixed condition made significantly greater gains learning the four two-letter GPCs across measures (median d?=?0.86), and no significant differences between groups on measures of the 11 one-letter GPCs common to both conditions. Findings add precision to understanding how rate and order of introducing GPCs influence children’s initial alphabet learning. Further study of empirically validated methods of alphabet instruction may benefit in particular those children most at risk for acquiring this foundational knowledge.

The authors analyzed the spellings of 179 U.S. children (age = 3 years, 2 months–5 years, 6 months) who were prephonological spellers, in that they wrote using letters that did not reflect the phonemes in the target items. Supporting the idea that children use their statistical learning skills to learn about the outer form of writing before they begin to spell phonologically, older prephonological spellers showed more knowledge about English letter patterns than did younger prephonological spellers. The written productions of older prephonological spellers were rated by adults as more similar to English words than were the productions of younger prephonological spellers. The older children s spellings were also more wordlike on several objective measures, including length, variability of letters within words, and digram frequency.  相似文献

Research suggests that children can learn new information via pretense. However, a fundamental problem with existing studies is that children are passive receivers of the pretense rather than active, engaged participants. This preregistered study replicates previous learning from pretense findings (Sutherland & Friedman, 2012, Child Development), in which children are passive observers of pretense, and extends to two additional conditions that require children to partially (with puppets) or fully (with costumes) embody a character. Children (N = 144, 24–79 months) learned equally well, and better than those in the control condition, from all three play scenarios. At a 2-week follow-up, learning was equally retained across embodiment conditions for older, but not younger, preschoolers. Future research should consider embodiment’s role for more complex material.  相似文献

Two studies ask whether scaffolded children (n = 243, 5–6 years and 9–10 years) recognize that assistance is needed to learn to use complex artifacts. In Study 1, children were asked to learn to use a toy pantograph. While children recognized the need for assistance for indirect knowledge, 70% of scaffolded children claimed that they would have learned to use the artifact without assistance, even though 0% of children actually succeeded without assistance. In Study 2, this illusion of self-sufficiency was significantly attenuated when observing another learner being scaffolded. Learners may fail to appreciate artifacts’ opacity because self-directed exploration can be partially informative, such that learning to use artifacts is typically scaffolded instead of taught explicitly.  相似文献

This study examined achievement, neuropsychological, and intervention outcomes at a mean age of 11 years in children with very low birthweight (VLBW, <1500 g) compared with a term-born control group. To assess the prevalence and correlates of specific learning disabilities (LD), the sample was limited to children without neurosensory disorders who had at least low average IQ. Participants included 31 children with <750 g birthweight, 41 with 750-1499 g birthweight, and 52 controls. The <750 g group obtained lower scores in math, IQ, and perceptual-organizational skills than the term-born group. The < 750 g group also had higher rates of past and present LD than the controls. Despite these differences, the groups did not differ significantly in rates of special education or tutorial/remedial assistance. These findings suggest that children with extremely low birthweight without gross physical or intellectual impairments are at higher risk for LD and cognitive deficiencies than their term-born peers and that further efforts are needed to improve identification and treatment of these learning problems.  相似文献

This study examined elementary school children's beliefs about learning and assessed the influences of such beliefs on their understanding of science texts. Eighty-three children, 46 from Grade 4 and 37 from Grade 6, were administered a questionnaire on children's implicit notions of learning. Children were also asked to read a science text and complete several tasks that assessed their understanding of text information. Results indicated that older children were more likely to hold constructivist views of learning, and they also performed better than younger children on the text-processing tasks. As well, children's views of learning were significantly related to depth of text understanding when age effects were controlled. This study extends current research on epistemological beliefs of university and high school students. Implications of children's beliefs about learning and their roles in knowledge construction are discussed. Copyright 2001 Academic Press.  相似文献

Challenges for researchers wishing to gain insights into student beliefs about mathematics and learning include the identification of prompts to which young children can respond easily and which have the potential to provide meaningful insights into their beliefs. This article reports on a selection of such prompts used within an exploratory study that investigated beliefs about mathematics, learning and helping factors for learning mathematics of eight children of 8 to 9 years of age. These prompts, described as creative interviewing procedures, are classified under the key categories of visual, verbal and text-based. The article provides brief details of the study as background but focuses on discussing the nature of the tasks, and, through the inclusion of a selection of responses, illustrates their potential value as research tools for gaining insights into young children’s beliefs about mathematics and learning. It seems that teachers could use the prompts to gain alternate perspectives into children’s beliefs which in turn might inform their instruction.  相似文献

The influence of different instructional presentations upon meaning and pronunciation acquisition in character learning was examined. High school students learned to identify a series of characters in terms of their associated pinyin and English translation prompts. Acquisition was shown to proceed more rapidly when the Chinese character was presented before rather than after the prompts. The addition of colour‐coded prompts led to superior learning. Retention over two weeks was greater in the case of characters presented before prompts with colour‐coding. These data are interpreted in terms of split attention, which arises when learners attend to multiple inputs simultaneously, and the beneficial effects of attending to a character prior to its prompts. The presentation of the Chinese character first and then its pinyin and colour‐coded English translation is recommended.  相似文献

Beliefs about learning and physical difficulties were explored in 50 younger children (M = 5.6, SD = 1.0 years) and 50 older children (M = 9.5, SD = 1.1 years). Participants were asked why they thought some children had learning or physical difficulties and whether children with these difficulties would always have them. The majority of older children were able to generate one or more ideas about the causes of learning and physical difficulties, but 58% of the younger children did not know the causes of learning difficulties and 42% did not know the causes of physical difficulties. Younger and older children thought that learning difficulties could be overcome with increased effort on the part of parents, teachers, and child, whereas physical difficulties were believed to be beyond anyone’s control. Results suggest that some aspects of children’s knowledge about causes and outcomes of learning and physical difficulties are limited. Research is needed to determine whether beliefs and misconceptions about learning and physical difficulties are associated with the quantity and quality of interpersonal interactions, and to determine the sources of children’s information as well as the accuracy of these sources.  相似文献
