Emerging parallel processing and increased flexibility during the acquisition of cognitive skills form a combination that is hard to reconcile with rule-based models that often produce brittle behavior. Rule-based models can exhibit these properties by adhering to 2 principles: that the model gradually learns task-specific rules from instructions and experience, and that bottom-up processing is used whenever possible. In a model of learning perfect time-sharing in dual tasks (Schumacher et al., 2001), speedup learning and bottom-up activation of instructions can explain parallel behavior. In a model of a complex dynamic task (Carnegie Mellon University Aegis Simulation Program [CMU-ASP], Anderson et al., 2004), parallel behavior is explained by the transition from serially organized instructions to rules that are activated by both top-down (goal-driven) and bottom-up (perceptually driven) factors. Parallelism lets the model opportunistically reorder instructions, leading to the gradual emergence of new task strategies. 相似文献

The resurgence of interest in early childhood education has been accompanied by an active debate about the most developmentally beneficial approach to preschool instruction. Some experts and the major early childhood organizations in this country advocate a child-centered or developmentally appropriate approach, whereas other experts advocate a teacher-directed, didactic approach. Until recently, the empirical evidence available to inform this controversy has been woefully thin. This article reviews the social and theoretical parameters of this debate about preschool instruction, articulates the core dimensions that have been portrayed as distinguishing child- from teacher-directed curricula, and examines the available research that can inform the debate. Our conclusions support those who encourage the adoption of child-centered curricula. Didactic approaches appear to undermine young children's motivation in and enjoyment of school in the short term and to have either neutral or negative ramifications for long-term achievement, despite some evidence of short-term gains. 相似文献

Much of the scholarship concerning African American culture is premised on the notion that it is a legacy of African origins but there has been essentially no attempt to document that relationship empirically. This paper briefly reviews existing evidence for cultural continuity in the Diaspora and then compares the responses of Black and Coloured South African and African Americans on measures of culture emic to African American populations. The observed patterns of psychometric performance, participants' responses, and the predictive utility of the measures employed were consistent with the thesis that despite inevitable variation, these three groups of the African Diaspora share similar orientations on the cultural themes assessed. This research hopes to initiate empirical work on the continuity thesis as it applies to connecting African American culture with a legacy of Africa and as related more broadly to the study of global Diasporas. 相似文献

Using data from a computer-based formative feedback system, we compare learning gains in the 8 weeks of school closures related to the COVID-19 pandemic in Switzerland with learning gains in the 8 weeks before these school closures. The school performance in mathematics and language of N = 28,685 pupils is modelled in second-order piecewise latent growth models with strict measurement invariance for the two periods under investigation. While secondary school pupils remain largely unaffected by the school closures in terms of learning gains, for primary school pupils learning slows down and at the same time interindividual variance in learning gains increases. Distance learning arrangements seem an effective means to substitute for in-person learning, at least in an emergency situation, but not all pupils benefit to the same degree. 相似文献

Although eye tracking has been used extensively to assess cognitions for static stimuli, recent research suggests that the link between gaze and cognition may be more tenuous for dynamic stimuli such as videos. Part of the difficulty in convincingly linking gaze with cognition is that in dynamic stimuli, gaze position is strongly influenced by exogenous cues such as object motion. However, tests of the gaze-cognition link in dynamic stimuli have been done on only a limited range of stimuli often characterized by highly organized motion. Also, analyses of cognitive contrasts between participants have been mostly been limited to categorical contrasts among small numbers of participants that may have limited the power to observe more subtle influences. We, therefore, tested for cognitive influences on gaze for screen-captured instructional videos, the contents of which participants were tested on. Between-participant scanpath similarity predicted between-participant similarity in responses on test questions, but with imperfect consistency across videos. We also observed that basic gaze parameters and measures of attention to centers of interest only inconsistently predicted learning, and that correlations between gaze and centers of interest defined by other-participant gaze and cursor movement did not predict learning. It, therefore, appears that the search for eye movement indices of cognition during dynamic naturalistic stimuli may be fruitful, but we also agree that the tyranny of dynamic stimuli is real, and that links between eye movements and cognition are highly dependent on task and stimulus properties. 相似文献

The learning style myth is a commonly held myth that matching instruction to a student's “learning style” will result in improved learning, while providing mismatched instruction will result in suboptimal learning. The present study used a short online reasoning exercise about the efficacy of multimodal instruction to investigate the nature of learning styles beliefs. We aimed to: understand how learning style beliefs interact with beliefs about multimodal learning; characterize the potential complexity of learning style beliefs and understand how this short exercise might influence endorsements of learning styles. Many participants who believed in the learning style myth supported the efficacy of multimodal learning, and many were willing to revise their belief in the myth after the exercise. Personal experiences and worldviews were commonly cited as reasons for maintaining beliefs in learning styles. Findings reveal the complexity of learning style beliefs, and how they interact with evidence in previously undocumented ways. 相似文献

Hindsight bias is a phenomenon that occurs when outcome knowledge interferes with the ability to accurately recall judgments made in a previous, naïve state. Also known as the “knew it all along” bias, we aimed to diminish the bias by having individuals take the perspective of a naïve other, as a way of encouraging acceptance that they had, in fact, not known it all along. Adult participants were given blurry-to-clear images incrementally until they were able to identify the object and were then re-presented with the same sequence of images and asked to make a judgment about when they had identified the item correctly the first time. They were also asked to judge when they thought a naïve peer (Experiments 1 and 2), or a naïve child (Experiment 2) could identify the objects. Results showed a robust hindsight bias in all perspectives, and sporadic success at eliminating the bias. When taking the perspective of a naïve peer, there were failures and successes; when taking the perspective of a naïve child, there was an ultra-debiasing, or a reverse hindsight bias. However, did the manipulation backfire? We conclude that while the manipulation of thinking like a naïve child may have eliminated the bias, participants seemed to use an “adults know best” rule rather than accepting past naivete for themselves. 相似文献

Education, in epistemological terms, presents an arena in which the development of knowledge and its transmission frame fundamentally distinct assignments: in social contexts knowledge exchange is prioritised to equip individuals as knowers; in theoretical contexts, an understanding of knowing as a state of mind is the primary objective. Distinguishing between education and its institutionalised product –the school–, this paper reviews the notion that today's modern classroom settings limit the applicability of neuroscience research by focusing on equipping individuals as knowers. In contrast, educational research has become increasingly grounded in brain sciences, with future premises examining artificial intelligence technologies (AI) targeted at enhancing learning and memory based on an understanding of the nature of knowing. Taking into account this bifurcation between education and school, this paper examines how the paths of educational, neuroscience, and AI research cross beyond school-enabled learning. This is contemplated across three sections. The first section examines the historical basis of the bifurcation between education and schooling. The second reviews the potential impacts of current neuroscience knowledge on educational implementations. The third discusses how and why neuroscience and AI technologies could be pertinent to educational discourse in the future. 相似文献
