The process of knowledge elaboration is considered from the perspective of cognitive load theory. This theory assumes that the available knowledge structures in long-term memory (LTM) are used to organize and guide cognitive processing in complex learning. Accordingly, the role of external instructional guidance in the process of knowledge elaboration could be described as providing a substitute for knowledge structures missing from LTM. Thus, the executive guidance in complex learning environments is shared between the person (based on his/her LTM knowledge structures) and another expert or instructional means. This article analyzes instructional implications of this assumption. Adaptive learning environments are suggested for tailoring knowledge elaboration processes to changing characteristics of individual learners. Means for identifying and predicting the learner's LTM-based executive guidance are proposed so that they can be utilized in the building of adaptive learning environments.  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

The conditions under which explicit instruction in checking, combined with worked examples, may be beneficial in learning how to translate sentences into algebraic equations was examined from the perspective of cognitive load theory. In two experiments it was shown that Grade 8 and 9 students were initially disadvantaged by the inclusion of a checking method. However, after a more substantial period of acquisition, students with a low level of mathematical knowledge performed significantly better after receiving checking instructions than those who did not receive checking instructions. In contrast, higher knowledge students were continually disadvantaged by the inclusion of a checking method. The positive effect of checking for lower knowledge students and the negative effect for higher knowledge students in this domain is a further example of the expertise reversal effect.  相似文献

Children with learning problems require early intervention. If it is evidence based and implemented with integrity and intensity, it will accelerate the academic progress of many students. This is the hope and expectation of the many supporters of responsiveness-to-intervention (RTI). A minority of children, however, will not respond sufficiently to such intervention because of learning disorders like specific learning disabilities (SLD). Some RTI models do not include research-backed methods to identify these children, nor do RTI practitioners often produce the data necessary to develop individualized instruction for them. The authors suggest practitioners go beyond typical RTI assessment data documenting responsiveness/ unresponsiveness to conduct comprehensive evaluations of these most difficult-to-teach students and to include in their evaluations carefully chosen cognitive measures. This special issue presents the work of teams of researchers, which suggests that cognitive and neuropsychological assessments can provide information to further understand SLD, which in turn can guide development of promising interventions.  相似文献

This study was designed to determine a word problem difficulty classification in children with arithmetic learning disabilities (ALD; n = 104) in comparison with typically achieving students (n = 44). We tested variables such as (a) semantic structure (Change, Combine, Compare, and Equalize), (b) operation (subtraction and addition), and (c) position of the unknown quantity in the problem. Facet theory with multidimensional scaling techniques (MINISSA) was used to analyze the underlying dimensions in the responses of each group of participants. Our results indicate that although the word problem difficulty classifications for the 2 groups of children were different, the position of the unknown quantity had a greater influence on the level of difficulty of story problems than other variables. The noncanonical problems--specifically, those with the unknown term in the first place--although difficult for both groups of children, were the most difficult problems for children with ALD.  相似文献

This paper describes a longitudinal study undertaken with 40 pre‐schoolers during their last six months in an early childhood centre and their first six months at school. The study presents an investigation of the pathways that child drawers and painters make towards representational depictions. As such its primary focus is on cognitive processes. Monthly samples of 40 children's drawings and paintings were collected over a 12‐month period that included the children's transition into formal schooling. CrossTabs analysis showed that the relevant cognitive abilities tended to present in clusters and that patterning may be a serious component both in its own right, as well as in facilitating representational depictions, as previously claimed by Booth.  相似文献

This paper uses the methodology of cross-case analysis to clarify connections and differences between two specific conceptual frameworks, multimodal social semiotics and constructionism, in particular in the ways they each deal with the idea of representation. It builds especially upon the idea of “distance” of digital representations with respect to usual representations, stressing the multidimensionality of this notion and possibilities for progress towards a shared framework for research about representations. The paper focuses on the cross-case analysis study of a “middle distance” dynamic digital artefact, MoPiX, by two teams sharing a common reference framework (constructionism), but with distinct views with regard to representations. The research yielded a distinction in the ways connections between representations are valued by the two approaches and their respective interpretations of meaning generation.  相似文献

Earlier research by the author indicated that many below average attainers do not remember number facts and use alternative strategies to obtain solutions to basic arithmetical problems. These alternatives were frequently seen as the best way of finding a solution.This paper considers the relationship between the various strategies used by mixed ability children aged 7 to 12. An analysis of alternatives suggests that the selection is not underpinned by regression through the learning sequence, but by regression dominated by the child's preference for certain strategies over others. Through the evaluation of a hierarchy of preferences, divergence between the strategies available to the less able and the more able child is revealed. The alternative strategies used are based either on counting — procedural strategies, or on the use of selected known knowledge — deductive strategies. Above average children have both available as alternatives; evidence of deduction is rare amongst below average children. The more able child appears to build up a growing body of known facts from which new known facts are deduced. Less able children — relying mainly on procedural strategies — do not appear to have this feedback loop available to them.The paper contends that, for some children, procedural methods do not encourage the need to remember; the procedure provides security. On the other hand, deductive methods initially enhance the ability to remember other basic facts and eventually help children make extensive use of facts that are known to remove the need to remember new ones. More able children appear to be doing a qualitatively different sort of mathematics than the less able.  相似文献

Different indicators are interesting for analyzing human learning processes. Recent studies analyze learning performance in combination with cognitive load, as an indicator for learners’ invested mental effort. In order to compare different measures of cognitive load research, the present study uses three different objective methods and one subjective method, reviewing the seductive details effect in a computer-based multimedia learning instruction. An experimental two-group design (N = 50) was used, with exposure to seductive details during learning as the between group factor. Eye movements were analyzed concerning the indicated cognitive activity and cognitive load was measured by the rhythm method (Park 2010; Park and Brünken 2015), the index of cognitive activity (ICA) (Marshall 2007), as well as by subjective ratings of mental effort and task difficulty (Paas 1992). Results confirm the seductive details effect for learning success with a decrease in retention and comprehension performance, an increase in total cognitive activity indicated by eye movements and significant higher cognitive load, indicated by rhythm method. The ICA values and the subjective ratings on mental effort and task difficulty show no difference in cognitive load between the groups. The results provide evidence of the suitability of different objective measures for a direct and continuous cognitive load assessment in multimedia learning. Further, the results show the benefit of combining different methods to gain detailed insight into information processing while learning with multimedia as well as a differentiated access to the single cognitive load factors.  相似文献

For three decades, social cognitive researchers have studied children's development of self-regulation as an achievement of socialization processes. I recount historically the emergence of a social cognitive perspective on self-regulation and identify its unique features. Two essential characteristics of students' self-regulated academic learning have been identified — their use of strategies and perceptions of self-efficacy. A social cognitive model of academic self-regulated learning is proposed that integrates triadic determinants of self-regulated learning (personal, behavioral, and environmental) on the basis of a strategic control loop. When students monitor their responding and attribute outcomes to their strategies, their learning becomes self-regulated, and they display increased self-efficacy, greater intrinsic motivation, and higher academic achievement.  相似文献

The purpose of this study was to determine if an instruction designed to facilitate planning, given by teachers to their class as a group, would have differential effects depending on the specific Planning, Attention, Simultaneous, Successive (PASS) cognitive characteristics of each child. A cognitive strategy instruction that encouraged planning was provided to the group of 19 students with learning disabilities and mild mental impairments. All students completed math worksheets during 7 baseline and 14 intervention sessions. During the intervention phase, students engaged in self-reflection and verbalization of strategies about how the arithmetic computation worksheets should be completed. The sample was sorted into one experimental and four contrast groups after the experiment was completed. There were four groups with a cognitive weakness in each PASS scale from the Cognitive Assessment System and one group with no cognitive weakness. The results showed that children with a cognitive weakness in Planning improved considerably (large effect size of 1.4), in contrast to those with a cognitive weakness in Attention (small effect size of 0.3), Simultaneous weakness (a slight deterioration and effect size of -0.2), Successive weakness (medium effect size of 0.4), and no cognitive weakness (small effect size of .2). These data showed that children with a Planning weakness benefitted from the instruction designed to help them be more plaful. Those children who received the planning-based instruction who were not low inplanning did not show the same level of improvement.  相似文献

An overview of the literature on developmental dyslexia is offered, moving historically from attempts to identify a single underlying deficit to more recent efforts to define different subtypes of this developmental disorder. Two approaches to the subtyping problem are illustrated and briefly discussed. It is suggested that many of the remaining questions in dyslexia research could be more profitably addressed within the context of a coherent model of reading behaviour. In the latter half of this review, the potential implications of some aspects of the interactive reading theories for the study of reading dysfunction are explored. Preparation of this review was supported by funds from the Medical Research Council of Canada, the Ontario Mental Health Foundation/COMSOC Provincial Lottery Grants Program, and The Hospital for Sick Children Foundation.  相似文献

One hundred and six undergraduates searched a hypermedia environment under three navigational conditions, wrote an essay measuring their comprehension, and completed a test of metacognition. The map conditions were spatial/semantic, spatial only, and none. Analyses revealed that a navigational map capable of incurring an integrative cognitive model of the meaningful relationships underlying website content incurs significantly more metacognitive load and higher levels of comprehension. When the map was incapable of revealing these relationships, metacognitive skills were of no value and compromised learning performance. The results demonstrate that a navigational map can create significantly more cognitive load; however, the nature of the load—whether germane or extraneous—is based on the degree to which the map permits integrative model construction during processing.  相似文献

To tailor instruction to levels of learner proficiency in a domain in adaptive learning environments, rapid on‐line methods of assessing learner knowledge and skills are required. Cognitive studies indicate that major factors in expert performance are organised structures in the person’s knowledge base. Measuring different levels of acquisition of such knowledge structures should be a major purpose of cognitive diagnostic assessment. Traditional tests may not provide reliable evidence for diagnostic purposes and are not suitable for dynamic learning environments. This paper discusses an alternative diagnostic approach based on monitoring immediate traces of students’ knowledge structures in working memory. Results of an experimental study applying this method to assessment of user reading skills are described. The study demonstrated a sufficiently high level of correlation (.66) between obtained measures and traditional test scores, and a substantial increase in reliability, with testing time reduced by a factor of 3.8.  相似文献

Spoken words have always been an important component of traditional instruction. With the development of modern educational technology tools, spoken text more often replaces or supplements written or on-screen textual representations. However, there could be a cognitive load cost involved in this trend, as spoken words can have both benefits and disadvantages based on essential characteristics of our cognitive architecture. This paper analyzes factors that might moderate the effectiveness of using spoken text in instruction by reviewing relevant studies in multimedia learning and considering cognitive load consequences of the transiency of spoken information. However, in contrast to earlier studies that considered spoken words in the context of a specific cognitive load effect, this paper provides a framework for evaluating potential instructional benefits of spoken text by analyzing various instructional situations depending on whether spoken text is used together with pictures and written text, and taking into account relations between presented sources of information.  相似文献
