玩具数量对3～6岁幼儿分享行为的影响     

唐慧琳  严娟 《南京晓庄学院学报》2011,(5):90-93,124

为了用实验的方法探讨玩具数量对3～6岁幼儿分享行为的影响,选取了某幼儿园小、中、大班各30名幼儿,将各年龄班的幼儿随机分成人数相等的三组,三组进行游戏时玩具的数量不等,即分别为玩具数量多于、等于和少于小组人数。结果表明：小班、大班的幼儿都表现出当玩具数量少于人数时,幼儿做出分享行为的人数明显多于玩具数量等于和多于幼儿人数的情况。但中班幼儿面对不同数量玩具时的分享行为差异不显著。另外,当玩具数量等于人数时,表现出了明显的年级差异,大班幼儿做出分享行为的人数显著多于小班和中班幼儿。当玩具数量多于人数或少于人数时,不同年级幼儿的分享行为差异不显著。本研究的结论是：玩具数量是影响分享行为的因素之一,随着玩具数量的减少,幼儿的分享行为在增加。  相似文献

Concept learning by pigeons: Matching-to-sample with trial-unique video picture stimuli     

Anthony A. Wright  Robert G. Cook  Jacquelyne J. Rivera  Stephen F. Sands  Juan D. Delius 《Learning & behavior》1988,16(4):436-444

Pigeons were trained to match-to-sample with several new methodologies: a large number of stimuli, computer-drawn color picture stimuli, responses monitored by a computer touch screen, stimuli presented horizontally from the floor, and grain reinforcement delivered onto the picture stimuli. Following acquisition, matching-to-sample concept learning was assessed by transfer to novel stimuli on the first exposure to pairs of novel stimuli. One group (trial-unique), trained with 152 different pictures presented once daily, showed excellent transfer (80% correct). Transfer and baseline performances were equivalent, indicating that the matching-to-sample concept had been learned. A second group (2-stimulus), trained with only two different pictures, showed no evidence of transfer. These results are discussed in terms of the effect of numbers of exemplars on previous failures to find concept learning in pigeons, and the implications of the positive finding from this experiment on abstract concept learning and evolutionary cognitive development.  相似文献   

Learning Is Moving in New Ways: The Ecological Dynamics of Mathematics Education     

Dor Abrahamson  Raúl Sánchez-García 《学习科学杂志》2016,25(2):203-239

Whereas emerging technologies, such as touchscreen tablets, are bringing sensorimotor interaction back into mathematics learning activities, existing educational theory is not geared to inform or analyze passages from action to concept. We present case studies of tutor–student behaviors in an embodied-interaction learning environment, the Mathematical Imagery Trainer. Drawing on ecological dynamics—a blend of dynamical-systems theory and ecological psychology—we explain and demonstrate that: (a) students develop sensorimotor schemes as solutions to interaction problems; (b) each scheme is oriented on an attentional anchor—a real or imagined object, area, or other aspect or behavior of the perceptual manifold that emerges to facilitate motor-action coordination; and (c) when symbolic artifacts are introduced into the arena, they may both mediate new affordances for students’ motor-action control and shift their discourse into explicit mathematical re-visualization of the environment. Symbolic artifacts are ontological hybrids evolving from things with which you act to things with which you think. Students engaged in embodied-interaction learning activities are first attracted to symbolic artifacts as prehensible environmental features optimizing their grip on the world, yet in the course of enacting the improved control routines, the artifacts become frames of reference for establishing and articulating quantitative systems known as mathematical reasoning.  相似文献

Comprehension evaluation and regulation in learning from science texts     

Jose C. Otero  Juan M. Campanario 《科学教学研究杂志》1990,27(5):447-460

Metacognitive variables influence students' learning from science texts. This article deals with the comprehension monitoring abilities of secondary school science students, one of the areas of metacognition which has drawn considerable attention from researchers. The aims of the study are, in particular: (a) to know the extent to which comprehension is monitored by secondary science students as revealed by inconsistency detection in manipulated science texts, and (b) to identify the strategies used to regulate comprehension by the students who detect the inconsistencies. The results indicate that knowing that one understands or fails to understand science texts could be as important a problem as understanding proper. Besides, some incorrect regulatory strategies used by students who notice the inconsistencies in the texts are identified. These could also have an annoying influence in the regulatory behavior of students when studying regular science texts.  相似文献   

成长的失落--关注大学新生入学心理适应   总被引：2，自引：0，他引：2

大学新生入学后，生活环境、生活条件、人际关系、学习方式与方法都不同了，这一系列的变化，逐渐使他们原有的习惯、心理结构与心理定势被打破，这时他们在心理上还残留有依赖性、理想化、盲目自信等心理特征。如此种种心理反应，都必须有一个适应期，期间他们感觉很突出的是成长过程的失落。  相似文献
