Problem solving in mathematics: the significance of visualisation and related working memory     

Jill Carden  Tony Cline 《Educational Psychology in Practice》2015,31(3):235-246

The importance of educational psychologists’ (EPs’) skills to the formulation of evidence-based educational strategies, as well as in response to learning difficulties, is demonstrated here in relation to mathematical problem solving. Initiatives to improve the link between mathematical skills from school to everyday life have drawn significantly on problem solving tasks. Through critical evaluation of research, the relevance of visualisation methods and working memory to problem solving is considered within this article. Studies suggest that differences exist in the effectiveness of particular visualisation methods, but that training can improve their utility and thereby problem solving performance. Additionally, differences between individuals and contexts can influence visualisation use, and some pupils experience specific difficulties in this area. Recommendations are made to enhance the teaching of visualisation as a strategy for problem solving, and to support those pupils with specific difficulties.  相似文献

湖南省工业集聚的空间关联性研究     

陈赤平  罗运辉  张紫琴 《湖南师范大学社会科学学报》2015,(3):109-117

湖南省各市州的工业总产值之间在空间上存在相关性,工业发展水平相近的市域有显著的集聚特性,但不同地区集聚程度存在显著差异。长株潭是我省工业发展的核心增长极,也是工业发展的热点区域;湘南部分地区和湘西地区是全省工业发展的“凹地”,处于工业集聚的边缘地带;工业发展的冷点区则集中在西北的市州。湖南省未来工业空间集聚格局,应该以长株潭为核心集聚区域,以连接长株潭与四大次级增长圈的交通道路和经济成长带为轴线,逐步向周边拓展,从而形成圈层状工业空间集聚结构。  相似文献

辽宁省第三产业重心与经济重心的变动及其关系     

关伟  曹佳宾 《辽宁师范大学学报(社会科学版)》2015,(2):181-187

运用区域重心的概念和计算方法,利用辽宁省14个地级市2000—2012年国内生产总值(GDP)、第三产业生产总值,计算出辽宁省各年第三产业重心、经济重心坐标及移动距离,分析出重心移动方向,定量地表示第三产业、经济区域差异的动态变化,从而对第三产业分布和经济分布的演变关系进行比较分析。结果表明:第三产业重心和经济重心位于辽宁省几何中心的东南面,第三产业分布和经济发展呈现不均衡性;第三产业重心、经济重心迁移方向基本一致,总体有缓慢向西南方向迁移的趋势,第三产业重心迁移的幅度大于经济重心,第三产业和经济的不协调性有所增长;第三产业重心、经济重心在经纬度上均呈现较高的正相关性,经济重心偏移与第三产业重心偏移的相互影响程度较高。  相似文献   

我国体育彩票销售额的空间异质性及影响因素分析          下载免费PDF全文

王成龙 《河北体育学院学报》2019,33(6):41-48

收集2013—2017年我国31个省份体育彩票销售额的面板数据和2017年各省份社会发展指标的相关数据，运用探索性空间数据分析方法（ESDA），对31个省份体育彩票销售额的空间异质性特征及影响因素进行研究。全局空间自相关分析结果表明，体育彩票销售额具有明显的空间聚集性，且呈显著的空间正相关性。经分析，发现31个省份体育彩票销售额不均衡，东部沿海省份的销售额高于西部省份，提出应重点关注西部地区的体育彩票事业发展。31个省份体育彩票销售呈现出以次冷区域为主，个别热点区域和次热区域相结合的特点，说明我国体育彩票销售的区域性寡占市场特征较明显，提出应加强省份间的沟通交流，促进各区域联动均衡发展。在影响因素方面，人均GDP、体育场地面积对体育彩票销售额具有显著性影响，其中人均GDP对南方的影响大于北方，体育场地面积对东北地区的影响大于西南地区，提出应进一步加大对体育场地建设的投入力度，以促进我国体育彩票事业的发展。  相似文献

1934年至1935年《申报》对江湾体育场的记述          下载免费PDF全文

刘亨 《体育科研》2019,(1):30-35

江湾体育场是上海市五角场地区的一个地标性建筑，它在1935年建成之后的八十多年中，对上海市民的体育文化生活产生了巨大的影响。《申报》作为中华人民共和国成立之前沪上最知名甚至是全国知名的报纸，它所刊登的报道较能真实地还原当时上海的社会风貌。通过查阅《申报》关于江湾体育场筹备和建设的报道，调查江湾体育场建设的动因、进程和民众对于它的态度，重构上海及全国民众对于江湾体育场的历史记忆。研究发现：1934-1935年间，《申报》对江湾体育场的报道主要集中在筹备过程和落成之后，筹备过程中的报道主要围绕体育场的建设规划和前期准备等方面；落成之后，报道的内容转变为以对体育场的介绍为主。  相似文献   

Guiding Low Spatial Ability Individuals through Visual Cueing: The Dual Importance of Where and When to Look     

Victoria A. Roach  Graham M. Fraser  James H. Kryklywy  Derek G.V. Mitchell  Timothy D. Wilson 《Anatomical sciences education》2019,12(1):32-42

Research suggests that spatial ability may predict success in complex disciplines including anatomy, where mastery requires a firm understanding of the intricate relationships occurring along the course of veins, arteries, and nerves, as they traverse through and around bones, muscles, and organs. Debate exists on the malleability of spatial ability, and some suggest that spatial ability can be enhanced through training. It is hypothesized that spatial ability can be trained in low-performing individuals through visual guidance. To address this, training was completed through a visual guidance protocol. This protocol was based on eye-movement patterns of high-performing individuals, collected via eye-tracking as they completed an Electronic Mental Rotations Test (EMRT). The effects of guidance were evaluated using 33 individuals with low mental rotation ability, in a counterbalanced crossover design. Individuals were placed in one of two treatment groups (late or early guidance) and completed both a guided, and an unguided EMRT. A third group (no guidance/control) completed two unguided EMRTs. All groups demonstrated an increase in EMRT scores on their second test (P < 0.001); however, an interaction was observed between treatment and test iteration (P = 0.024). The effect of guidance on scores was contingent on when the guidance was applied. When guidance was applied early, scores were significantly greater than expected (P = 0.028). These findings suggest that by guiding individuals with low mental rotation ability “where” to look early in training, better search approaches may be adopted, yielding improvements in spatial reasoning scores. It is proposed that visual guidance may be applied in spatial fields, such as STEMM (science, technology, engineering, mathematics and medicine), surgery, and anatomy to improve student's interpretation of visual content.

认知负荷对乒乓球运动员注意空间的影响*     

杨〓义  岳珍珠 《广州体育学院学报》2019,(2):99-101

目的 同时注意空间中多个目标刺激对于乒乓球运动员非常重要。考察认知负荷对青少年乒乓球运动员注意分布的影响。方法：实验中采用计算机行为实验，控制认知负荷（同时注意的目标数量为2、4或6个），并且在不同注意范围（离中央注视点3°、6°和9°视角）的位置上同时呈现刺激，要求被试对刺激的亮度变化做辨别反应。结果：:认知负荷对于乒乓球运动员的注意范围有显著调节。当刺激个数为2时，在3°和6°视角条件下呈现的刺激反应时均显著快于9°视角条件下的刺激。当刺激个数为4时，视角为3°条件下的反应时快于视角为6°和9°时的反应时，而视角为6°时又比视角为9°时的反应时显著要快。当刺激个数为6时，视角为3°时的反应时均快于视角为6°和9°时的反应时。结论：当前研究证明随着认知负荷增加，乒乓球运动员注意焦点范围显著缩小。可以通过测量运动员在高负荷条件下注意焦点的范围来进行运动员的选拔。  相似文献
