儿童认知发展中的利用缺陷研究

首先介绍了儿童认知发展中利用缺陷的定义,然后通过对前人的研究文献的分析说明了利用缺陷存在的证据和儿童利用缺陷的发展特征。并从个体可获得的心理资源、背景知识、元记忆、对先前无效策略的抑制和包括智商、性别、温度、动机等的非发展性原因来揭示利用缺陷的影响因素。最后展望了将来可能研究的几个重要问题并简单的说明了利用缺陷对于我们教育的启示。     

探索小班化教学的优化路线

发掘小班课堂教学优势 充分关注每个学生的个性差异,与学生的生活经验对接,与社会生活实践结合,从教学观念、教学内容、教学资源和教学方式方法上,建构活跃、丰富、和谐的生命课堂.帮助学生形成个性化学习方式,把学习变成人的主体性、能动性、独立性不断生成、张扬和发展的过程,获取最大化学习效益,银小初步发掘了小班化课堂教学的内在优势.     

开春后小麦管理措施

一是弱苗的管理。这类苗叶色淡、叶片窄小、长势差、个体弱,管理上以促为主。对地力较肥,冬前追过肥,田间湿度一般的晚播弱苗,应早耕勤锄,增温保湿,早春施肥可推迟进行。对土层薄,前期未追肥、墒情差、麦苗下部叶片枯黄的缺肥弱苗,应及早追肥灌水,对     

Web2.0环境下专题文献检索途径分析

随着网络技术的发展,新的信息发布和检索方式不断涌现,专题文献检索在沿用传统检索途径的同时,还必须熟悉新的检索方式和途径。本文介绍了博客信息检索、维基网站信息检索、开放存取文献检索等新的学术信息检索途径。     

新课改背景下中学物理合作学习课堂操作模式

本文根据中学生思维活跃,课外知识比较丰富,渴望与他人沟通、交往等特点,从实施合作学习的理论依据、课堂操作模式及实施过程几方面,对如何在中学物理课堂教学中实施“合作学习”进行了探索,试图通过课堂上师生、生生之间的全方位互动与合作,营造良好的学习氛围,使学生在掌握知识,提高思维能力的同时,逐渐形成与人合作的良好心理品质和技能,以适应现代社会的要求。     

立足自然实验教学培养创新思维能力

观察是指人利用感觉器官,在自然条件下有目的、有计划地感知客观事物的活动.用观察的方法认识自然事物,在科学研究中最普遍也是最基本的方法,它对培养学生自行推理和创新思维的能力起着非常重要的作用.如教学,卵石的形成》一课时,让学生把搜集来的卵石摆在桌子上进行观察,讨论:这些卵石的形状有什么特点?各种卵石是否是同一种岩石?在什么地方最容易找到它,既然不是同一种岩石为什么会有相同的形状呢?通过一系列的问题,使学生自己很自然地提出了卵石是怎样形成的问题.此时,我就因势利导,指导学生观察、实验去探索有关的事实真相,作为探求和应用知识的依据.根据卵石多发现在河边这一事实,提出为什么在河边容易找到石子?我们要想知道这一秘密应该怎么办?学生会答:应该到河边亲自观察去.此时出示投影片,让学生进行实地考察.通过考察发现一个秘密,学生会自然推想到,卵石的形成可能是在河水的冲击搬运过程中逐渐形成的这一结论.     

On the same page in sporting dyads: does dissimilarity on 2 x 2 achievement goal constructs impair relationship functioning?

This study examined the extent to which 2 x 2 achievement goal constructs (Elliot, 1999) were associated with key relational perceptions (i.e., relationship commitment, relationship satisfaction) for members of athlete-athlete dyads. Both members from 82 regional-level partnerships (mean age = 22.72, SD = 3.83) were recruited from a variety of dyadic sports (e.g., tennis, badminton, rowing). Actor-partner interdependence model analyses revealed that greater dissimilarity between partners on mastery-approach and performance-approach goals was associated with lower commitment and satisfaction. Mastery goals displayed positive actor effects with respect to both relationship perceptions, whereas performance-avoidance goals were negatively related to commitment (i.e., actor and partner effects) and satisfaction (i.e., partner effect). These results indicate that achievement goal constructs may align with important interpersonal perceptions in athlete dyads.     

谈谈奥林匹克篮球后备队员的训练方法

过去一年里的比赛,对于我们国家队来说是很不顺利的一年。经对具体情况的分析,主要原因是一些训练问题。一些专家认为,青年队教练员们训练效果不佳是我们水平难以提高的主要原因之一。在这一重要训练阶段,对奥林匹克预备队员的系统训练缺乏独特见解。现代篮球运动中的高超技巧都是建立在身体素质、快速技术和良好反应这些比赛所必需的因素之上的。从这一点出发,对奥林匹克预备队员的训练提出以下建议: 一、尽可能采取强化训练。二、要进行多年的系统身体训练。     

Comparison of force-related performance indicators between heavyweight and lightweight rowers

The aim of this study was to examine biomechanical variables relating to the force production of men's Lightweight (LW) and Heavyweight (HW) rowing pairs. Seven HW and seven LW coxless pairs were studied under a range of stroke rates, from 20 spm to race rating (average of 33.7 spm for the HWs and 33.9 spm for the LWs). Each crew was equipped with biomechanical apparatus allowing the measurement of gate force, horizontal oar angle, and boat velocity. The HW crews exhibited significantly higher (p < 0.05) values for all variables examined, at all rates. Peak handle force was 26.2% to 30.2% higher in the HW group. Average handle force ranged from 18.7% to 22.1% higher than the LW group. Work per stroke was found to be 26% to 28% higher for the HW crews, and Power Per Kilogram was also greater for the HW crews, from 24.0% to 29.2%. The LWs were observed to be consistently, but not significantly, slower than the HWs (from 96.9% at the race situation, to 98.7% at 28 spm). These observations are important when considering biomechanical performance indicators in rowing, as significant changes in performance indicators may lead to only minimal alteration in boat velocity.
