Diagrams are effective tools for problem solving. However, previous findings indicate that students generally do not use diagrams spontaneously. This study examined task‐related factors that may influence the spontaneity of diagram use. Experiment 1 compared two possible explanations: the first, that the length‐relatedness of the story context of the problem (i.e. whether it involves the measurement of length) determines the likelihood of diagram use; and the second, that the cognitive cost of transforming the situation described in the word problem to an abstract diagrammatic representation is the more important factor. Four math word problems, differing in their story context and structure, were administered to eighth‐grade Japanese students (n = 125) to solve. The results provide support for the cognitive transformation cost explanation. The results of experiment 2, in which the problems were administered to students in both Japan (n = 291) and New Zealand (n = 323), confirm this finding.

ABSTRACT

Medical and health science graduate students report greater anxiety problems than the general population, but they are less likely to seek treatment due to cultural and logistical barriers. One preventative approach that overcomes these barriers is web-based cognitive behavioral therapy (webCBT). It is unknown whether webCBT is effective for preventing anxiety escalation within this population. A randomized controlled trial was conducted, comparing the effects of webCBT versus a control group (CG). Medical university students (n=594; Mage=27; 67% female; 80% Caucasian) completed online baseline measures and four assigned online activities. Measures were re-administered after approximately three months. There was a small interaction effect between time of assessment and treatment condition. Anxiety severity was lower in the webCBT (M[SD]=2.88[3.36]) versus CG condition (M[SD]=3.69 [3.35]) at follow-up. This effect was moderate for students with mild, versus minimal, anxiety at baseline. The proportion of students with possible anxiety disorder was lower in the webCBT (4.5%) versus CG (8.5%) condition, and the proportion of mildly anxious students with a clinically significant increase in symptoms was lower in the webCBT (10%) versus CG (20%) condition. WebCBT may aid in preventing anxiety escalation in this population, particularly for at-risk students who report mild anxiety symptoms.  相似文献

小学生表征数学应用题策略的实验研究   总被引:10,自引:0,他引:10       下载免费PDF全文
通过一个2(成功与否)×2(提示与否)×2(题型)的混合实验设计,对小学五年级学生解决和差应用题的表征策略进行了研究.结果表明:(1)与比较应用题的表征相类似,小学生对和差应用题的表征也存在着直译策略和问题模型策略;(2)不成功组解题者在表征和差应用题时倾向于运用直译策略,而成功组的解题者更倾向于运用问题模型策略,这导致了成功者与不成功者在列式上的差异,特别是在不一致题型上表现得更明显;(3)在读题前给以“请注意理解这道题的意思”这样简单的提示,对不成功的解题者对和差问题的正确表征并不能起到作用;(4)成功的和差应用题解题者和不成功的解题者在列式正确性的自我评价上存在显著差异.  相似文献

The teaching of cognitive strategies is a potentially effective intervention technique for some students with acquired neurological injuries; however, educators have only infrequently reported on the systematic application of cognitive strategies to the academic challenges of this population. This study represents such an attempt by investigating the effects of a self-instruction strategy on the academic performance of a student with acquired neurological damage. The intervention programme pertained to performing 2-digit by 1-digit multiplication problems and consisted of: (1) a six-step multiplication procedure; (2) self-instruction cues; and (3) procedural prompts. The intervention package resulted in improved performance on the multiplication task with levels being maintained despite fading of procedural prompts and self-instruction cues. Results are discussed in terms of implications for training and future research.  相似文献

To determine whether and how learning is biased by competing task-irrelevant information that creates extraneous cognitive load, we assessed the efficiency of university students with a learning paradigm in two experiments. The paradigm asked participants to learn associations between eight words and eight digits. We manipulated congruity of the digits’ ink colour with the words’ semantics. In Experiment 1 word stimuli were colour words (e.g., blue, yellow) and in Experiment 2 colour-related word concepts (e.g., sky, banana). Marked benefits and costs on learning due to variation in extraneous cognitive load originating from processing task-irrelevant information were evident. Implications for cognitive load theory and schooling are discussed.  相似文献

Canadian university students (n=48) solved simple addition problems in a true/false verification task with equations in digit format (3+4=8) or written English format (three+four=eight). Participants reported their solution strategy (e.g. retrieval or calculation) after each trial. Reported use of calculation strategies was much greater with word (41%) than digit stimuli (26%), and this difference was exaggerated for numerically larger problems. Word-format costs on reaction time (RT) were correspondingly greater for large than for small problems, but this Format×Size RT effect was bigger for true than for false equations. The results demonstrate that surface format affects central, rather than only peripheral, stages of cognitive arithmetic.  相似文献

Abstract

The ability of learning disabled and average students’ to recognize and identify words was investigated. Two informal reading measures, the Sundbye Minimal Contrast Phonics Test and an oral reading sample, were administered to three groups. The groups were composed of learning disabled students evidencing reading problems (LD), average students matched with the learning disabled group on reading level and IQ (YN), and average students matched with the learning disabled group on chronological age and IQ (ON). The LD group and average readers did not differ on identification of symbol‐sound associations, word recognition proficiency, the ability to detect and correct word recognition errors, and the ability to use information within the text to recognize words. However, the LD and ON group differed on mean number of word recognition errors. Educational implications of the findings were discussed and a profile of the word recognition skills of learning disabled children was presented.  相似文献

Mathematics textbooks sometimes present worked examples as being generated by particular fictitious students (i.e., person-presentation). However, there are indicators that person-presentation of worked examples may harm generalization of the presented strategies to new problems. In the context of comparing and discussing worked examples during extended classroom instruction, the current study compared the impact of person-presentation to strategy labels on students' posttest accuracy and ratings of strategy generalizability. Five algebra teachers and their 168 students used worked examples either presented using fictitious students or with a strategy label during a multiweek unit on equation solving, with teachers randomly assigned to condition. All students compared and discussed the worked examples. In this context, we found no effect of condition on student accuracy at posttest, nor on their ratings of the generalizability of the presented strategies. We discuss why previously found negative effects of person-presentation may not have extended to this context.  相似文献

The present study examined the effects of an error correction strategy on the spelling accuracy of students with emotional and/or learning disabilities. The strategy, which asked students to spell a word, view a correct model, and then correct their errors, was compared to a traditional strategy that asked students to write words three times each while viewing a correct model. Results showed that students learned more words in the error correction condition than in the traditional condition. The error correction treatment was shown to be an effective strategy that reduced the number of repetitive spelling practice trials, and was preferred by students.  相似文献

This study aims at determining the structure of the representation constructed by adults to solve multiple-step arithmetic word problems. We show that this structure is isomorphic to the structure of the situation described in the text of the problem. In effect, dynamic problems, which describe sequential events, are more likely to be solved by sequential strategies than are static problems. In other words, the order of succession of subgoals reached by individuals for the resolution is determined by the order of succession of subgoals explicitly described in the text of the problem. However, an alternative mental representation is constructed by low span individuals when its cognitive cost is not too high and, therefore, certain static problems are solved by a sequential strategy as well. We conclude that the probability of the construction of an alternative representation to the one induced by the text of the problem depends on its cost and the relative amount of cognitive resources it releases.  相似文献

ABSTRACT

By saving and storing information, we use digital devices as our external memory stores, being able to offload and temporarily forget saved contents. Storm and Stone [2015. Saving-enhanced memory: The benefits of saving on the learning and remembering of new information. Psychological Science, 26(2), 182–188] showed that such memory offloading can be beneficial for subsequent memory performance. Saving already encoded items enhanced recall of items encoded after saving. In the present study, we did not only replicate saving-enhanced memory but found saving-enhanced performance for unrelated cognitively demanding tasks. Participants solved more modular arithmetic problems when they were able to offload a previously studied word list, compared to trials without the possibility to offload. Thus, saving of recently encoded items entailed a general benefit on subsequent cognitive performance, beyond encoding and retrieving word lists. We assume that offloading frees participants from the need to maintain offloaded items. Gained resources can then be used for subsequent tasks with high cognitive demands. In a nutshell, memory offloading can help to reduce the amount of information that has to be processed at a given time, efficiently delegating our limited cognitive resources to the most relevant tasks at hand while currently irrelevant information are safely stored outside our own memory.  相似文献

The purpose of this study was to investigate the contributions of domain-general cognitive resources and different forms of arithmetic development to individual differences in pre-algebraic knowledge. Children (n = 279, mean age = 7.59 years) were assessed on 7 domain-general cognitive resources as well as arithmetic calculations and word problems at start of 2nd grade and on calculations, word problems, and pre-algebraic knowledge at end of 3rd grade. Multilevel path analysis, controlling for instructional effects associated with the sequence of classrooms in which students were nested across Grades 2-3, indicated arithmetic calculations and word problems are foundational to pre-algebraic knowledge. Also, results revealed direct contributions of nonverbal reasoning and oral language to pre-algebraic knowledge, beyond indirect effects that are mediated via arithmetic calculations and word problems. By contrast, attentive behavior, phonological processing, and processing speed contributed to pre-algebraic knowledge only indirectly via arithmetic calculations and word problems.

The results of a randomized controlled trial of repetition-lag training in older adults with amnestic mild cognitive impairment (aMCI) are reported. A modified repetition-lag training procedure with extended encoding time and strategy choice was used. The training required discriminating studied words from non-studied lures that were repeated at varying intervals during the test phase. Participants were assessed pre/post using untrained measures of cognition and self-report questionnaires. Primary outcome measures were recall of unrelated word pairs both immediately following presentation and following a delay. Secondary outcomes were a measure of attention, cognitive flexibility, and visual working memory. Participants were also asked to report on the frequency of cognitive failures and mood before and after training. Participants (N = 31) were randomized into either the treatment or a no-contact control group and attended the clinic twice per week over a four week period. Twenty-four participants completed the study (twelve in each group). Results indicated that the training group improved at recalling unrelated word pairs after a delay. There were no significant effects of training on other outcomes, self-reported cognitive failures or mood. The results are discussed along with suggestions for future research.  相似文献

Prior research by Hartwig and Dunlosky [(2012). Study strategies of college students: Are self-testing and scheduling related to achievement? Psychonomic Bulletin &; Review, 19(1), 126–134] has demonstrated that beliefs about learning and study strategies endorsed by students are related to academic achievement: higher performing students tend to choose more effective study strategies and are more aware of the benefits of self-testing. We examined whether students’ achievement goals, independent of academic achievement, predicted beliefs about learning and endorsement of study strategies. We administered Hartwig and Dunlosky’s survey, along with the Achievement Goals Questionnaire [Elliot, A. J., &; McGregor, H. A. (2001). A 2 × 2 achievement goal framework. Journal of Personality &; Social Psychology, 80, 501–519] to a large undergraduate biology course. Similar to results by Hartwig and Dunlosky, we found that high-performing students (relative to low-performing students) were more likely to endorse self-testing, less likely to cram, and more likely to plan a study schedule ahead of time. Independent of achievement, however, achievement goals were stronger predictors of certain study behaviours. In particular, avoidance goals (e.g., fear of failure) coincided with increased use of cramming and the tendency to be driven by impending deadlines. Results suggest that individual differences in student achievement, as well as the underlying reasons for achievement, are important predictors of students’ approaches to studying.  相似文献
