中美基础教育课外体育活动的比较研究

运用文献资料法、访谈法、比较分析法和逻辑法，对中美基础教育课外体育活动的价值取向、政策文件、组织管理、场地设施、运动时间及实施效果进行梳理、分析和比较，从中得出以下启示：要坚持课外体育活动健身育人的价值；学校体育政策要向课外体育活动倾斜，并注重政策的落实；构建课外体育活动的三级体系，促进家校社三方联动；加快社区体育建设，引导体育消费升级；布置体育作业，保证课外运动时间；立足实际问题，让学生从课外体育活动中受益。以邻为镜比较优劣得失，但不能生搬硬套，要从传统体育文化中吸收养分，促进青少年身心健康，促进我国课外体育活动改革与发展。     

“自学·议论·引导”教学法的基本原理与操作要义

自学·议论·引导包括以学定教、情智相生、活动致知、最近发展四个基本原理,以及以下四个操作要义:紧扣核心知识,促成知识生产;根据变化情境,融通多种策略;激活思维能量,优化学习品质;瞄准学力发展,奠基和谐人格。这些原理和要义在较大程度上与新课程基本理念相吻合,是对新课程精神的实践。

对外汉语教学视角下的汉字笔画分类

化解对外汉语教学中＂汉字难＂的问题,应对笔画重新分类。按笔画笔向折转与否,可将笔画＂三分＂为横、竖、撇、捺、点、提六个基本笔画,折、钩、弯三个特殊笔画和多个复合笔画;基本笔画可再＂三分＂为点画、线画和半线画;特殊笔画＂折＂使线画、半线画折转成直角,＂钩＂转成钝角,＂弯＂转成圆弧。占笔画多数的复合笔画都是基本笔画折、钩、弯而成的。     

中国农村社区基本公共品供给的合作机制

从基本公共品类型与供给方式来看,农村社区基本公共品类型复杂多样、合作机制呈现多元主导格局;从筹资来源渠道来看,农村社区基本公共品资金来源渠道由传统单一型向多元筹资方式转变;从决策机制来看,农村社区基本公共品供给决策机制由传统威权型逐步向协商治理模式转向;从合作能力的影响因素来看,影响农村社区基本公共品合作供给能力的基本因素有利益关联度、集体经济实力、村委会权威水平、村民参与水平以及相关宏观政策五个主要方面。     

从理论宣传角度审视五四时期“问题与主义”之争

20世纪初的＂问题与主义＂之争早已尘埃落定,但它所警告的教条主义空谈理论的危险并没有随之消失。＂问题与主义＂之争中提出的宣传＂主义＂和＂学理＂的方法,对我们今天的理论宣传仍有很大启发。

Writer identification approach based on bag of words with OBI features

Handwriter identification aims to simplify the task of forensic experts by providing them with semi-automated tools in order to enable them to narrow down the search to determine the final identification of an unknown handwritten sample. An identification algorithm aims to produce a list of predicted writers of the unknown handwritten sample ranked in terms of confidence measure metrics for use by the forensic expert will make the final decision.Most existing handwriter identification systems use either statistical or model-based approaches. To further improve the performances this paper proposes to deploy a combination of both approaches using Oriented Basic Image features and the concept of graphemes codebook. To reduce the resulting high dimensionality of the feature vector a Kernel Principal Component Analysis has been used. To gauge the effectiveness of the proposed method a performance analysis, using IAM dataset for English handwriting and ICFHR 2012 dataset for Arabic handwriting, has been carried out. The results obtained achieved an accuracy of 96% thus demonstrating its superiority when compared against similar techniques.     

Effects of pairs of problems and examples on task performance and different types of cognitive load

In two studies, we investigated whether a recently developed psychometric instrument can differentiate intrinsic, extraneous, and germane cognitive load. Study I revealed a similar three-factor solution for language learning (n = 108) and a statistics lecture (n = 174), and statistics exam scores correlated negatively with the factors assumed to represent intrinsic and extraneous cognitive load during the lecture. In Study II, university freshmen who studied applications of Bayes' theorem in example–example (n = 18) or example–problem (n = 18) condition demonstrated better posttest performance than their peers who studied the applications in problem–example (n = 18) or problem–problem (n = 20) condition, and a slightly modified version of the aforementioned psychometric instrument could help researchers to differentiate intrinsic and extraneous cognitive load. The findings provide support for a recent reconceptualization of germane cognitive load as referring to the actual working memory resources devoted to dealing with intrinsic cognitive load.
