The acquisition of a reading vocabulary for abstract and concrete words was examined in 62 second-grade children. Words had been learned as part of a basal reader program or as part of outside reading. Word recognition speed and reading accuracy were examined for abstract and concrete words using lexical decision and word naming tasks. The size of the concreteness effect was similar for both processing tasks. In neither task did concreteness influence reaction times, but abstract words were read with less accuracy than concrete words in both tasks. Further, these concreteness effects in reading accuracy were larger for words that were part of a basal reading program than for words acquired during free reading. We conclude that word meaning influences the entry of words at a time when children are developing a sizeable reading vocabulary.  相似文献

Twenty-five adolescents with learning disabilities were randomly assigned to either a keyword mnemonic condition or an experimenter-directed rehearsal condition and were individually taught 16 difficult vocabulary words, including 8 concrete and 8 abstract words. After an instructional period, students were given a test of literal recall as well as a comprehension test of their ability to apply newly acquired vocabulary words in a different context. Results indicated that mnemonically trained students outperformed control students on both abstract and concrete words, and on recall tests as well as on comprehension tests. Implications for vocabulary instruction as well as theories of learning disabilities are discussed.  相似文献

This paper reviews research suggesting that interest and importance are separate constructs mediated by concreteness and mental imagery, especially in expository text or other genres where concreteness and importance often diverge. Important expository material can be relatively more interesting or less interesting. If important expository material is concrete it tends to be interesting and well recalled. If important expository material is abstract and not well linked to concrete elaboration or examples it tends to be less interesting and less well recalled. Concrete elaboration of abstract ideas tends to improve students' recall. There appears to be no harm in adding concrete detail to well structured, coherent text to promote interest unless enough is added so that a new text with a different coherence emerges. Making already concrete text more emotionally interesting may have little effect. Using a coherent text structure that adequately implies or signals importance and supporting important information with concrete explanation are key text design implications. Dual Coding Theory provides a systematic theoretical account of the findings in this area.  相似文献

The present study aimed to provide evidence outlining whether the type of stimuli used in teaching would provoke differing levels of recall across three different academic age groups. One hundred and twenty-one participants, aged 11–25 years, were given a language-based memory task in the form of a wordlist consisting of 15 concrete and 15 abstract words, presented either visually, acoustically, or a combination of both audio and visual presentation. The study found that the presence of cognitive overload was greater in the older academic age participants than in the younger groups and that as academic experience increased, the visual presentation of the target stimuli produced greater levels of recall than was the case with acoustic and audio-visual presentation. Overall the findings indicate that cognitive overload increases with age, as the younger-age groups were found to have significantly higher levels of word recall in the audio-visual condition than the older groups.  相似文献

A longstanding debate concerns the use of concrete versus abstract instructional materials, particularly in domains such as mathematics and science. Although decades of research have focused on the advantages and disadvantages of concrete and abstract materials considered independently, we argue for an approach that moves beyond this dichotomy and combines their advantages. Specifically, we recommend beginning with concrete materials and then explicitly and gradually fading to the more abstract. Theoretical benefits of this “concreteness fading” technique for mathematics and science instruction include (1) helping learners interpret ambiguous or opaque abstract symbols in terms of well-understood concrete objects, (2) providing embodied perceptual and physical experiences that can ground abstract thinking, (3) enabling learners to build up a store of memorable images that can be used when abstract symbols lose meaning, and (4) guiding learners to strip away extraneous concrete properties and distill the generic, generalizable properties. In these ways, concreteness fading provides advantages that go beyond the sum of the benefits of concrete and abstract materials.  相似文献

Individuals' relative awareness of thematic and taxonomic relations is influenced by factors such as language and background knowledge. Relatively weak in Korean language skills and also having relatively limited social opportunities, Korean deaf adolescents might be different from hearing adolescents in how they make decisions in taxonomically and thematically associated entities represented by pictures and words. Experiment 1 indicated that deaf adolescents had longer reaction times than hearing adolescents in a forced-choice decision-making task. Both deaf and hearing adolescents had shorter reaction times and higher accuracies with pictures than with words, but deaf adolescents' differences were bigger than those of hearing adolescents. Experiment 2 further showed that deaf adolescents had lower accuracies than hearing adolescents in a priming task of living-nonliving categorization. Both deaf and hearing adolescents had shorter reaction times with taxonomic than with thematic categories, but deaf adolescents' difference was bigger than that of hearing adolescents. In conclusion, Korean deaf adolescents were aware of thematic and taxonomic relations less than hearing adolescents in general. They were more likely than hearing adolescents to show the advantage of pictures over words in their performance in conceptual activities and to prefer taxonomic to thematic associations for written words in Experiment 2.  相似文献

There is mixed evidence as to whether concrete manipulatives (e.g., toy animals) are better than abstract manipulatives (e.g., counters) for teaching mathematical concepts to children. Concreteness is defined as the amount of extraneous information a manipulative provides, and in this study we aimed to unpick which dimensions of concreteness influence manipulative choice. Researchers, teachers, and parents completed a comparative judgment task comparing images of manipulatives varying in different dimensions of concreteness, selecting which they would choose to teach arithmetic to children. The findings indicated homogeneous, 3-dimensional manipulatives were the most preferred across all groups to teach arithmetic to children, regardless of more extraneous features. This contradicts research recommendations to minimize the use of concrete manipulatives due to their distractive qualities. Instead, it suggests that some concrete features may be preferred in more naturalistic contexts. More research is required to investigate how different dimensions of concreteness influence learning outcomes for children both in artificial research contexts and in practice.  相似文献

传统的观点认为人们总是用具体的源域映射抽象的目标域。实际上,具体或抽象并不是某一个域的必然属性。王文斌提出,两个域之间的映射通过具体与抽象两两组合而成,即以具体隐喻具体、以具体隐喻抽象、以抽象隐喻具体、以抽象隐喻抽象。隐喻研究多集中在隐喻产物上,而对施喻者使用隐喻的目的研究较少。基于此,本文探讨施喻者在运用这四种不同映射方式时不同的交际目的。  相似文献

The concreteness of training materials influences learning and—perhaps more importantly—transfer. Building on prior research finding abstract representations best facilitated transfer to a game task, we conducted a similar study using training figures varying in concreteness but directly assessed transfer to modular arithmetic problems. Training figures: (a) were purely abstract, (b) were abstract but with features relevant to the transfer task, or (c) included additional concrete-relevant features. We hypothesized that concreteness—or number of relevant features—would be positively correlated with learning and transfer—especially among younger and/or lower-ability students. Although there was no overall difference in initial learning, the concrete-relevant and abstract-relevant features independently facilitated near-transfer, where concrete-relevant features supported lower-reasoning students. For far-transfer, eighth-graders benefited from the abstract-relevant features, whereas sixth-graders required additional concrete-relevant features. These findings suggest that concreteness interacts with learner and task characteristics to produce learning and transfer outcomes.  相似文献

The present study investigates the effects that concreteness fading has on learning and transfer across three grade levels (4–6) in elementary school science education in comparison to learning with constantly concrete representations. 127 9- to 12-years-old elementary school students studied electric circuits in a computer-based simulation environment, where circuits remained concrete (bulbs) throughout the learning or faded from concrete to abstract (bulbs to resistors). The most important finding was that the outcomes seemed to be influenced by a developmental factor: the study found a significant interaction between condition and grade level in relation to learning outcomes, suggesting that the outcomes generally improved as a function of grade level, but that there were notable differences between the conditions regarding the improvement of outcomes across the three grades. According the results, learning with constantly concrete representations either took less time or resulted in better learning compared to concreteness fading. Because transfer is one of the central arguments for concreteness fading, a somewhat surprising finding was that the concrete condition succeeded at least as well as the fading condition on transfer tasks. The study also discusses why the results and issues related to the conceptualisation and operationalisation of central concepts in the study call for caution towards generalization and for more research with young learners across different grades.  相似文献

Experts are more proficient in manipulating and translating between multiple representations (MRs) of a given concept than novices. Studies have shown that instruction using MR can increase student understanding of MR, and one model for MR instruction in chemistry is the chemistry triplet proposed by Johnstone. Concreteness fading theory suggests that presenting concrete representations before abstract representations can increase the effectiveness of MR instruction; however, little work has been conducted on varying the order of different representations during instruction and the role of concreteness in assessment. In this study, we investigated the application of concreteness fading to MR instruction and assessment in teaching chemistry. In two experiments, undergraduate students in either introductory psychology courses or general chemistry courses were given MR instruction on phase changes using different orders of presentation and MR assessment questions based on the representations in the chemistry triplet. Our findings indicate that the order of presentation based on levels of concreteness in MR chemistry instruction is less important than implementation of comprehensive MR assessments. Even after MR instruction, students display an asymmetric understanding of the chemical phenomenon on the MR assessments. Greater emphasis on MR assessments may be an important component in MR instruction that effectively moves novices toward more expert MR understanding.  相似文献

The present experiment was carried out to test the hypothesis that the use of the written mode increases the working memory load. Second and fourth graders were orally presented with series of unrelated words which they were required to recall in sequence. Each subject had to recall five different lists in the following conditions: oral alone, written, oral with a concurrent task (tapping, categorization, drawing). Participants recalled more words in the oral condition than in either the written mode or the `oral and categorization' conditions. Moreover, second graders performed better in the oral mode than in the `oral and drawing condition'. This trend was not significant with older children. Finally, the tapping task did not affect children's performance. The results are consistent with our cognitive load hypothesis.  相似文献

The degree to which the concreteness of prose material presented in an auditory fashion would interact with learners' lateral preference under different right hemispheric presentation conditions was investigated with 96 normal adults. Forty-eight subjects with consistent right preference patterns and a like number of bilateral individuals were either instructed to image, given a visual-spatial interference task, or given no instructions before listening to passages which differed in abstractness. As predicted across conditions, learners recalled a significantly greater number of ideas when the passage was concrete. Importantly, the abstractness was found to interact with subjects' inferred cerebral dominance. Whereas instructions to image and visual interference had little significant effect on mixed dominant subjects, for more consistently lateralized subjects imagery instructions increased and right-hemispheric interference decreased concrete recall. The results were interpreted in terms of visual and verbal encoding concomitant with cerebral lateralization.  相似文献

Learning algebra is difficult for many students in part because of an emphasis on the memorization of abstract rules. Algebraic reasoners across expertise levels often rely on perceptual-motor strategies to make these rules meaningful and memorable. However, in many cases, rules are provided as patterns to be memorized verbally, with little overt perceptual support. Although most work on concreteness focuses on conceptual support through examples or analogies, here we consider notational concreteness—perceptual-motor supports that provide access into the dynamic structure of a representation itself. We hypothesize that perceptual support may be maximally beneficial as an initial scaffold to learning so that later static symbol use may be interpreted using a dynamic perspective. This hypothesis meshes with other findings using concrete analogies or examples, which often find that fading these supports over time leads to stronger learning outcomes. In an experiment exploring this hypothesis, we compared gains from the fading out of dynamic concrete physical motion of symbols during instruction with the introduction of motion over the course of instruction. In line with our theoretical perspective, concreteness fading led to significantly better achievement than concreteness introduction after Day 2 of the intervention.  相似文献

Younger children’s free recall from episodic memory is typically less organized than recall by older children. To investigate if and how repeated learning opportunities help children use organizational strategies that improve recall, the authors analyzed category clustering across four study-test cycles. Seven-year-olds, 10-year-olds, and young adults (N = 150) studied categorically related words for a free-recall task. The cognitive processes underlying recall and clustering were measured with a multinomial model. The modeling revealed that developmental differences emerged particularly in the rate of learning to encode words as categorical clusters. The learning curves showed a common pattern across age groups, indicating developmental invariance. Memory for individual items also contributed to developmental differences and was the only factor driving 7-year-olds’ moderate improvements in recall.  相似文献

This study examined the effect that systematically loading story presentations with criterion information has on the recall of abstract and concrete prose. Results indicated that aal plus picture presentations were most effective for the learning of both abstract and concrete content. Furthermore, the loading of additional detail into visual presentations resulted in greater recall than with simple pictures and also provided a greater supplementary effect to oral prose.  相似文献

Concreteness fading has been proposed as a general instructional approach to support learning of abstract mathematics and science concepts. Accordingly, organizing external knowledge representations in a three-step concrete-to-idealized sequence should be more beneficial than the reverse, concreteness introduction, sequence. So far, evidence for the benefits of concreteness fading come mainly from studies investigating learning of basic mathematics concepts. Studies on learning natural science concepts are scarce and have not implemented the full three-step-sequence. In an experimental classroom study (N = 70), we compared concreteness fading and concreteness introduction in high school science education about electromagnetic induction using a detailed assessment. Furthermore, we explored whether these sequences differentially affect the use of the different representations during instruction. Both sequences were equally effective and there were no differences in using the representations. We discuss why our results question the proposed advantages of concreteness fading and highlight conceptual differences and learning goals across domains.  相似文献
