Background: Teachers’ conceptions and misconceptions about neuroscience are crucial in establishing a proper dialogue between neuroscience and education. In recent years, studies in different countries have examined primary and secondary school teachers’ conceptions. However, although preschool education has proved its importance to later academic outcomes, there is limited investigation of neuroscience conceptions focused exclusively on preschool teachers.

Purpose: The present study sought to explore preschool teachers’ conceptions and misconceptions about neuroscience in an Argentine setting.

Sample, design and methods: We used quantitative and qualitative approaches to explore concepts about neuroscience, including specific neuromyths. Data were collected using a 24-statement questionnaire and 5 in-depth interviews. The survey was administered to 204 teachers of children between the ages of 0–5-years in Argentina.

Results and conclusions: Results from this exploratory study suggested a relatively high level of general knowledge of neuroscience amongst the preschool teachers in the study. However, three particular issues seemed unclear for teachers: memory, plasticity and the myth that ‘we only use 10% of the brain’. Specifically, ‘memory’ was understood as ‘learning by heart’; neural underpinnings of memory and plasticity processes were unknown; and the myth that we only use 10% of the brain was used to explain individual differences in intelligence in a straightforward way. In addition, anecdotal evidence was used by teachers to justify their conceptions about neuroscience. Finally, the wider implications of these results for bridging neuroscience and education are discussed.  相似文献

Medical schools in the United States continue to undergo curricular change, reorganization, and reformation as more schools transition to an integrated curriculum. Anatomy educators must find novel approaches to teach in a way that will bridge multiple disciplines. The cadaveric extraction of the central nervous system (CNS) provides an opportunity to bridge gross anatomy, neuroanatomy, and clinical neurology. In this dissection, the brain, brainstem, spinal cord, cauda equina, optic nerve/tract, and eyes are removed in one piece so that the entire CNS and its gateway to the periphery through the spinal roots can be appreciated. However, this dissection is rarely, if ever, performed likely due to time constraints, perceived difficulty, and lack of instructions. The goals of this project were (i) to provide a comprehensive, step‐by‐step guide for an en bloc CNS extraction and (ii) to determine effective strategies to implement this dissection/prosection within modern curricula. Optimal dissection methods were determined after comparison of various approaches/tools, which reduced dissection time from approximately 10 to 4 hours. The CNS prosections were piloted in small group sessions with two types of learners in two different settings: graduate students studied wet CNS prosections within the dissection laboratory and medical students used plastinated CNS prosections to review clinical neuroanatomy and solve lesion localization cases during their neurology clerkship. In both cases, the CNS was highly rated as a teaching tool and 98% recommended it for future students. Notably, 90% of medical students surveyed suggested that the CNS prosection be introduced prior to clinical rotations. Anat Sci Educ 11: 185–195. © 2017 American Association of Anatomists.  相似文献

Byrnes and Fox present a sophisticated approach to the development of useful relations between cognitive neuroscience and education. Their approach, which is similar to approaches advocated by other educational psychologists, emphasizes the importance of findings in cognitive neuroscience to the building of educationally useful models of learning. In contrast to that defensible approach is a popular but simplistic approach that tries to relate the results of individual cognitive neuroscience studies directly to the improvement of teaching. The advantages of the sophisticated approach presented by Byrnes and Fox are discussed and supported for their important roles in the development of productive relations between cognitive neuroscience and education.  相似文献

Objective: To determine whether spinal cord decompression plays a role in neural cell apoptosis after spinal cord injury. Study design: We used an animal model of compressive spinal cord injury with incomplete paraparesis to evaluate neural cell apoptosis after decompression. Apoptosis and cellular damage were assessed by staining with terminal deoxynucleotidyl transferase (TdT)-mediated deoxyuridine triphosphate nick-end labelling (TUNEL) and immunostaining for caspase-3, Bcl-2 and Bax. Methods: Experiments were conducted in male Spragne-Dawley rats (n=78) weighing 300-400 g. The spinal cord was compressed posteriorly at T10 level using a custom-made screw for 6 h, 24 h or continuously, followed by decompression by removal of the screw. The rats were sacrificed on Day 1 or 3 or in Week 1 or 4 post-decompression. The spinal cord was removed en bloc and examined at lesion site, rostral site and caudal site (7.5 mm away from the lesion). Results: The numbers of TUNEL-positive cells were significantly lower at the site of decompression on Day l, and also at the rostral and caudal sites between Day 3 and Week 4 post-decompression, compared with the persistently compressed group. The numbers of cells between Day 1 and Week 4 were immunoreactive to caspase-3 and B-cell lymphoma-2 (Bcl-2)-associated X-protein (Bax), but not to Bcl-2, correlated with those of TUNEL-positive cells. Conclusion: Our results suggest that decompression reduces neural cell apoptosis following spinal cord injury.  相似文献

As part of individual interviews incorporating whole number and rational number tasks, 323 grade 6 children in Victoria, Australia were asked to nominate the larger of two fractions for eight pairs, giving reasons for their choice. All tasks were expected to be undertaken mentally. The relative difficulty of the pairs was found to be close to that predicted, with the exception of fractions with the same numerators and different denominators, which proved surprisingly difficult. Students who demonstrated the greatest success were likely to use benchmark (transitive) and residual thinking. It is hypothesised that the methods of these successful students could form the basis of instructional approaches which may yield the kind of connected understanding promoted in various curriculum documents and required for the development of proportional reasoning in later years.  相似文献

Sensory training, based on the latest research findings in neuroscience and perceptual psychology, is beginning to make a significant impact on practice in the treatment of language impairments. This training has three novel aims: the stimuli are designed to engage and develop specific brain processing modules; the training task difficulty is dynamically modulated, leading to the most efficient learning for an individual; and the tasks are presented as highly motivating computer games to encourage the long periods of training that result in optimal learning. The published results are impressive, with improvements averaging two years in language age following four weeks of intensive training. In this article, David Moore, Professor of Auditory Neuroscience at the University Laboratory of Physiology in Oxford and Chief Technology Officer for Mind Weavers Ltd at the Oxford Centre for Innovation, explores the research leading to these initiatives. While the mechanisms of the training remain controversial, it seems likely that, in the future, automated training of this type will make a major impact on practice in special education and in many other fields.  相似文献

Cut scores, estimated using the Angoff procedure, are routinely used to make high-stakes classification decisions based on examinee scores. Precision is necessary in estimation of cut scores because of the importance of these decisions. Although much has been written about how these procedures should be implemented, there is relatively little literature providing empirical support for specific approaches to providing training and feedback to standard-setting judges. This article presents a multivariate generalizability analysis designed to examine the impact of training and feedback on various sources of error in estimation of cut scores for a standard-setting procedure in which multiple independent groups completed the judgments. The results indicate that after training, there was little improvement in the ability of judges to rank order items by difficulty but there was a substantial improvement in inter-judge consistency in centering ratings. The results also show a substantial group effect. Consistent with this result, the direction of change for the estimated cut score was shown to be group dependent.  相似文献

大脑是一个复杂而动态的系统,受学习、训练以及各种经验等因素的影响,其结构和功能都会出现动态的修复或重组,也就是体现出所谓的可塑性。当前认知神经科学研究表明,在个体发展的生命全程中枢神经系统都具有一定的可塑性,如儿童大脑、成人大脑以及非正常人大脑均具有可塑性。由于在个体发展的不同阶段可塑性是动态变化的,而且不同脑区在不同时间其功能活性以及可塑性本身也不一样,所以,在制定相关的教育方案或干预措施时,必须综合考虑影响大脑可塑性的这些因素,加强教育的针对性和实效性,实现科学的保护脑、使用脑、开发脑;充分利用大脑的可塑性,重视早期教育;提供丰富而适宜的教育环境,全面开发大脑的潜能,促进大脑的整合式发展;全面了解影响大脑可塑性的因素,寻求大脑可塑性与教育的最佳结合点。  相似文献

This critical and reflective literature review examines international research published over the last decade to summarise the different kinds of measures that have been used to explore cognitive load and critiques the strengths and limitations of those focussed on the development of direct empirical approaches. Over the last 40?years, cognitive load theory has become established as one of the most successful and influential theoretical explanations of cognitive processing during learning. Despite this success, attempts to obtain direct objective measures of the theory's central theoretical construct – cognitive load – have proved elusive. This obstacle represents the most significant outstanding challenge for successfully embedding the theoretical and experimental work on cognitive load in empirical data from authentic learning situations. Progress to date on the theoretical and practical approaches to cognitive load are discussed along with the influences of individual differences on cognitive load in order to assess the prospects for the development and application of direct empirical measures of cognitive load especially in technology-rich contexts.  相似文献

Increasingly, connections are being made between neuroscience and education. At their interface is the attempt to ‘bridge the gap between conscious minds and living brains’. All too often, the two sides pursue a reductionist strategy of excluding the other. A middle way, promoted by Sankey in the context of values education, is emergentism: our conscious mental states are the product of brain processes but are not reducible to them. This paper outlines Sankey’s emergentist position and raises two objections: What are emergent properties and What is the process of emergence? Sankey accepts neuroscience but rejects an eliminative materialist version on three grounds: materialism, reduction and determinism. All three are rebutted. His account of the neuronal, synaptic self is considered and found wanting. Finally, some positive remarks are made about the contribution eliminativism might make to values education. The conclusion reached is this: attempts to bridge the gap between mind and brain have not been successful and Sankey’s emergentism is no exception. This is one divide in education which will not be crossed.  相似文献

How individual differences in cognitive ability influence acquisition and transfer of strategic comparison skills was examined as a function of learning difficulty. Using a cognitive test battery, we classified forty-nine participants into three cognitive ability groups. Participants in each group were trained to compare similar (difficult training) or dissimilar (easy training) stimuli and then transferred to compare novel stimuli. Results suggest that overall individual differences in cognitive ability dictate the optimality of strategic skill development, though the effect of training difficulty on transfer performance varies with cognitive ability. Individuals with a midrange of cognitive ability are the most sensitive to the training context. Results are discussed with respect to the characteristics of strategic skills acquired and transferred.  相似文献

In their target article, Byrnes and Fox (1998) argue that many of the recent findings from the field of cognitive neuroscience have particular importance for education. In our commentary, we lend support to their contention by reporting on some of our work that has potential relevance to the proposed interface between cognitive neuroscience and education. Specifically, we discuss the findings from several studies investigating the neuropsychology of intellectual giftedness, and sex differences in the brain, each of which suggest a unique functional organization that differentiates gifted from average ability adolescents, as well as males from females. We further propose that the translation of cognitive neuroscience findings into specialized classroom instructional methods which capitalize on the plasticity of the brain, as well as the apparent individual differences in its functional organization, may be the most significant challenge facing those in the front-lines of educational practice.  相似文献

ABSTRACT

This paper seeks to examine the parallels between many aspects of conductive education and the conceptual framework of Feuerstein's theory of mediated learning. Conductive education is not a treatment administered to remedy some pathology, as is the case with many therapies, but rather a system of education aimed at developing the whole individual. How this process is achieved may be enlightened by reference to Feuerstein's model of mediated learning experience (MLE). Two key aspects of Feuerstein's theory are examined: first, structural cognitive modifiability (SCM), which maintains that every individual's cognitive structures are capable of modifiability, despite barriers of retardation ‐ very much in line with modern neuroscience and its model of the brain as a plastic and adaptable system; and secondly, mediation (MLE), which is the process whereby a more initiated individual acts as a mediator between culture and child and thereby directs the child into preparing an adequate response. A detailed examination with exemplars is then undertaken into the mediation of many different aspects of development, including the three essential mediation processes of intentionality and reciprocity, transcendence and meaning. Finally, the implications of Feuerstein's theory for models of research and evaluation are considered, particularly the need for more qualitative and interactional approaches which maintain ecological validity.  相似文献

This paper reviews research literature on cognitive load measurement in learning and neuroimaging, and describes a mapping between the main elements of cognitive load theory and findings in functional neuroanatomy. It is argued that these findings may lead to the improved measurement of cognitive load using neuroimaging. The paper describes how current measures of cognitive load cannot accurately show the distinction between different types of cognitive load in different learning conditions, and existing approaches to cognitive load assessment are limited in terms of their precision and methodology. A literature review discusses the conceptual framework of Sweller's [Sweller, J. (1994). Cognitive load theory, learning difficulty, and instructional design. Learning and Instruction 4, 295-312; Sweller, J. (1999). Instructional design in technical areas. Camberwell, Australia: ACER Press] cognitive load theory, and describes various approaches to load measurement and their limitations. The paper then describes how the core components of cognitive load - intrinsic, extraneous, and germane load - may be observable using neuroimaging techniques, and argues for the exploration of new links between education research and neuroscience.  相似文献

Routes to research for novice undergraduate neuroscientists   总被引：2，自引：2，他引：0  
Undergraduate students may be attracted to science and retained in science by engaging in laboratory research. Experience as an apprentice in a scientist's laboratory can be effective in this regard, but the pool of willing scientists is sometimes limited and sustained contact between students and faculty is sometimes minimal. We report outcomes from two different models of a summer neuroscience research program: an Apprenticeship Model (AM) in which individual students joined established research laboratories, and a Collaborative Learning Model (CLM) in which teams of students worked through a guided curriculum and then conducted independent experimentation. Assessed outcomes included attitudes toward science, attitudes toward neuroscience, confidence with neuroscience concepts, and confidence with science skills, measured via pre-, mid-, and postprogram surveys. Both models elevated attitudes toward neuroscience, confidence with neuroscience concepts, and confidence with science skills, but neither model altered attitudes toward science. Consistent with the CLM design emphasizing independent experimentation, only CLM participants reported elevated ability to design experiments. The present data comprise the first of five yearly analyses on this cohort of participants; long-term follow-up will determine whether the two program models are equally effective routes to research or other science-related careers for novice undergraduate neuroscientists.  相似文献

For 3years, I have been teaching neuroscience courses by using computer conferencing to complement the traditional lectures. Typically, the conferencing involved local, on‐campus students, although one semester the class was combined from on‐campus and off‐campus students. For most of my 33‐year teaching career, I had used the teaching approach that most professors use, which is what educational theorists call “instructivist.” Critics call that “stand and deliver.” Lecturing is an efficient way to dispense organized information, but it does not ensure learning nor is it very effective in showing students how to learn on their own.

Instructivism can be enriched by complementing it with “constructivist” approaches. Constructivists argue that there is a direct relationship between the amount of learning that occurs and the extent to which the environment provides a rich source of engaging experiences in which students construct their own knowledge and understanding. I have found that such an environment is readily provided by computer conferencing.

In my teaching of neuroscience, I have used a network software system (FORUM) for small student groups to conduct a variety of constructivist learning activities. Within weekly deadlines, students worked in groups at their own pace and time of convenience. My impression of the advantages of such conferencing for constructivist activities include the promotion of socialization in “cyberspace,” providing an environment for team learning, the reduction of social problems in face‐to‐face instruction, increased teaching and learning efficiency, more comprehensive means for assessing student learning, and improved quality of student work.  相似文献

Momentum is continuing to grow in the circulation of neuroscientific discourse, informing aspects of how we live but affecting too how we think about education and learning. Neurologically informed intrusions into education frequently align with psychology which has until now largely adopted a ‘medical model’, supporting policies and practices which ultimately invoke psychopathology and arguably render individual young people more vulnerable to various forms of social and educational exclusion. This paper urges caution in respect of understandings of educational neuroscience that focus on individual deficits and diagnoses. Rather it holds in mind the broader historical context for neuroscience and its implications for our understandings of what it is to be human in the twenty first century and thereafter for education and learning. Theoretical resources from critical and affective neuroscience but also critical educational psychology are brought together specifically to support the principles of inclusionist policies and practices in education.  相似文献

Abstract

?Multitiered systems of reading instruction and intervention, including response to intervention, are widely used in early reading by schools to provide more intense services to students who need them. Research using randomized controlled trials has compared innovative Tier 2 interventions to business-as-usual Tier 2 approaches and established a number of important components that compose effective Tier 2 interventions in early reading. The purpose of this study was to test the impact of a Tier 2 intervention with Tier 2 compared to Tier 1 instruction alone using regression discontinuity. A cut score was used to assign first-grade students at risk for reading difficulties to Tier 2 intervention plus Tier 1 instruction. Students who missed the cut score in the control group received Tier 1 instruction only. Students in the treatment group, just below the cut score, made greater gains on the SAT10 total score and the individual subtests than students just above the cut score. Outcomes were not significant on oral reading fluency.  相似文献
