新城幼儿园科学育儿知识讲座 科学育儿知识讲座 主讲人: 高志勤 一、儿童早期教育有没有价值, 1、早期经验对人的身心发展具有重要作用与影响。(脑科学研究发现，儿童早期生活经验能改变脑的生化形态和结构;心理学研究，早期教学方式影响儿童自我意识、情绪、行为的正常发展，甚至影响人的未来。) 2、早期教育不仅有利于儿童发展，也有利于家庭幸福、社会稳定与发展。(我国政府已把儿童早期教育视为基础教育的一部分，提到提高民族素质、消除贫困和实施科教兴国战略的高度来认识和重视。) 所以，那些忽视、漠视甚或敌视儿童早期教育的种种观点、看法都是过时了的。当然，不科学的、有缺陷的儿童早期教育不权不能创造上述价值，使人们热切的期待化为泡影，而且还可能带来种种严重后果，甚至毁灭儿童的幸福. 二、儿童早期教育有没有可能性与必要性, 1、儿童早期教育离不开三大要素:学习性、成熟性和动机性。 2、无数实验研究和教育实践均证明，婴幼儿具有巨大的学习潜能，这种潜能有时超过了以往人们的想象。(曾性初教授实验;卡尔?威特的教育) 3、但许多人并不明白儿童早期教育的两个不等式——有效性不等于科学性;可能性不等于必要性。 4、潜能开发不能拔苗助长，更不能搞掠夺式开发。(早期识字实验:“神童教育”反思) 所以，应理性地而不是狂热地、盲目地看待“早期教育热”。要用可持续发展的观点、终身教育的观点来看待儿童早期教育的目的。 三、儿童早期教育是否就是智力开发、技能训练或升学准备, 1、从理论上看，人们常常将儿童早期教育窄化为“智力开发”(智力开发虽是儿童早期教育的内容之一，但决不是一切。德育弱化，心育缺失，甚至，这个概念的科学化值得商榷。)。 2、从实践中看，人们又把智力开发异化为知识传授及技能(读、写、算、诵、唱、舞、琴、棋、、画等)训练。(国际21世纪委员会:凯茨“习得性愚蠢) 3、无论是教育还是“家长”，似乎自愿被卷入集体无意识之中，智育唯一、升学第一、你追我赶、不亦乐乎，许多儿童早期教育变成了为实现成人功利性理想与梦想甚或虚荣的工具。(“电脑热”、“外语热”、“艺术热”的冷思考) 4、关于儿童早期教育的片面化认识、以讹传讹的“神童”故事，也许将断送孩子的一生。(典型悲剧实例剖析) a special tool to measure half a point the rotor shaft runout and simultaneous measurement of two coupling flutter testing, it should meet the requirements.

Install the coupling housings to ensure embedded rotor coupling within a concave shoulder, and rotor clearance meets the design requirements. 6.4, 6, wearing construction technology of generator rotors demonstration 6.4.6.1 construction preparation and conditions through the stator before loading check and confirm to confirm air tightness test of the stator and stator mechanical, electrical, instrumentation and control and other related work had been completed.

Ends bearing end cover with connection of the stator plate or gourds by exclusive lug on the end face of a temporary low-hanging on the 孩子对排尿的行为没有敏感的反应;孩子的内裤太紧、局部没有清洗尿渍刺激等。 环境因素有:突然换新环境;气候变化如寒冷等。此外，孩子入睡前饮水过多;吃了西瓜等含水量多又有利尿作用的水果;父母在孩子夜间有便意时没有及时把尿等都会造成孩子尿床。 孩子睡眠过沉也是原因之一，据有关人士对尿床的孩子进行脑电图观察，的确存在着此因素。只要找到原因有针对性地给予纠正，孩子尿床现象必将大大减少并最终不再尿床。 经常尿床的孩子往往胆小、敏感、易于兴奋或过于拘谨。所以，父母还应从培养孩子的性格入手，来纠正尿床现象。 怎样实施音乐益智法, 要想让音乐发挥益智健脑的神奇魔力，成为打开少年儿童心灵的钥匙，光知道益智原理和选曲原则还不行，具体的实施，有时与效果有十分密切的关系。 1(乐曲的选择 不同旋律、速度、力度的音乐，对人体的生理、心理会产生不同的作用，起到不同的益智效果。一个人所属的民族、家庭素质、文化背景、性格特点、兴趣爱好也各不相同，因此，选曲不能千篇一律。 一般来说，3岁以下的孩子多选用简单、欢快、节奏感强不伴歌词的音乐曲目，3,6岁的孩子应选带歌词的歌曲，鼓励他们“听”、“唱”结合;而学龄儿童一般选用纯音乐作品，并加以解释，另用一部分有词歌曲来调节;10岁以上的孩子，就要选取一部分内容较深的交响乐了。 此外，乐曲的选择，还要以孩子的生理状态为依据。例如消化功能不好，厌食、挑食较明显的孩子，要选取和缓柔畅、庄重典雅的乐曲;大脑发育有轻度障碍，反应迟缓的孩子，应选择轻松活泼的乐曲;如孩子体质虚弱，易感冒、咳嗽，则应选取慷慨激昂、恢弘博大的乐曲。 孩子的性格也应作为选曲时的参考。孩子调皮好动，注意力难以集中，应选敦厚稳重、节奏平缓的音乐;性格内向，少言寡语的，则应选择热烈的乐曲;好哭，容易伤感的孩子，多选些开朗明快的乐曲。 2(时间的安排 音乐益智，要持之以恒，不能贪图一时的效果，应该每天坚持播放音乐或演奏、演唱。一般来说，音乐益智每天可进行两次，每次20分钟左右。 3(参与的方式 音乐益智对孩子来说，有被动参与和主动参与两类方式。 被动参与以欣赏乐曲为主，可以采用立体声耳机收听，也可以用录音机在室内或湖边、林中等安静、幽雅的环境中播放，但孩子喜动厌静，对音乐不会有太大的兴趣。因此，不能强迫a special tool to measure half a point the rotor shaft runout and simultaneous measurement of two coupling flutter testing, it should meet the requirements. Install the coupling housings to ensure embedded rotor coupling within a concave shoulder, and rotor clearance meets the design requirements. 6.4, 6, wearing construction technology of generator rotors demonstration 6.4.6.1 construction preparation and conditions through the stator before loading check and confirm to confirm air tightness test of the stator and stator mechanical, electrical, instrumentation and control and other related work had been completed. Internal cleaning of stator, high power vacuum the surface of the stator. Stator and rotor magnetic Center drainage is complete. In conjunction with the quality, mechanical, electrical and other relevant persons to finally cleaning check the stator, which is clean and free of any debris. Worn rotors check and confirm confirm before loading the rotor air tightness test, electrical test work has been completed. In conjunction with the quality, mechanical, electrical and other relevant persons to finally clean the rotors checked, its interior is clean and free of any debris. By quality, mechanical, electrical and other professionals to conduct an examination of the rotor, confirm the wear condition of the rotor. Special equipment inspection and rotor through the preparation tool before loading inventory, check to confirm that it appears intact, complete tool, tools required for use of wire rope that has a factory certificate and test report; wire rope should select the safety factor ? 6; hoist testing qualified; road have been equipment authorized Visa temporary support ties should be a hardwood. Ends bearing end cover with connection of the stator plate or gourds by exclusive lug on the end face of a temporary low-hanging on the 他们规规矩矩地坐在椅子上，一本正经地听音乐，可以在孩子游戏或吃饭时，甚至在做功课时播放。有不少人认为做作业时开录音机，会干扰孩子的注意力，影响作业的正确率，其实这是一种误解。 实践证明:做作业时播放优美舒缓的乐曲，只要音量适宜，不仅不会影响学习，还会使孩子对所做功课记得更牢。原因在于:做作业用的是管逻辑、语言、概念的左脑，而音乐只作用于右脑。做作业时，只要注意力已集中在书本上，轻柔的乐曲就会不知不觉地刺激孩子的右脑，使两侧大脑得到均衡的锻炼，根本不会加重左脑的负担。 白天播放音乐，音量控制在50分贝左右为宜，而孩子在睡觉前、做作业时，则应开到40分贝的音量，这是最适合于人体功能的音量。一般来说，催眠、镇静情绪的音乐，音量稍小一些;温和、舒畅的乐曲，音量中等，约50,55分贝，总的原则是让孩子听到音乐后不是嫌烦，而是出现轻松舒适的感觉。如学校让孩子听音乐益智，可放在下课时、做体操时或课外活动时。 主动参与，则要求少儿积极参与音乐实践，如演奏乐器，演唱歌曲，载歌载舞。主动参与更能直接影响孩子的思想态度，提高少儿的艺术兴趣，促进视、听和四肢运动的协调发展，培养积极进取的参与精神，加强自信心，进而达到开发智力的效果。有关资料明，经常操作乐器的儿童，其语言逻辑、抽象思维能力均高于同龄儿水平。 据观察，性格外向，好动不好静，爱幻想的孩子，采用被动参与的方式较好;而性格偏于孤僻、内向的孩子，则应积极诱导他们去主动地参与。 4(环境的选择 运用音乐进行儿童智力开发，实施时的环境十分重要。环境布置的合理，可以收到事半功倍的效果;反之，则达不到预期的成效。 对孩子们来说，音乐益智时的场地必须整洁、美观、宽敞，最好在树荫下、花园中，这样会增强益智效果。如果在室内，就要注意保持空气清新，周围要摆设一些盆景、花卉，以增添诗情画意之感，窗帘以淡雅、柔和的色调为好。 环境的色彩与益智也有关系。在橙色或黄色为基调的环境中接受音乐，会使人产生温暖、欢畅的感觉;蓝色或绿色能使人产生安全和镇定感;浅蓝色或白色能渲染出纯洁的意境。因此，对性格内向、身体羸弱的孩子，应布置以红、黄为主的兴奋色彩:对急躁外向、调皮好动的孩子，则应给他们以蓝、绿等光线柔淡的镇静色彩的音乐环境 幼儿益智游戏四则 思维能力是一个人智力结构的核心，家长可以利用与孩子一起做游戏的机会开发他们的智力，提高他们的思维能力。 a special tool to measure half a point the rotor shaft runout and simultaneous measurement of two coupling flutter testing, it should meet the requirements.

Ends bearing end cover with connection of the stator plate or gourds by exclusive lug on the end face of a temporary low-hanging on the 种音色的变化表现出来，使人能产生喜悦、忧伤、激动等不同的感受，其感染力是任何乐器无法比拟的，因而世界上几乎每个国家都有为小提琴谱写的乐曲。 现在许多人都想学习小提琴，但实际接触到它后又会感到有许多困难。尤其是幼儿，若要选择这样一件乐器，家长下决心是非常重要的。 许多家长认为，为孩子选择乐器的关键是要看孩子在这方面是否能成才。当然，要想成才，就必须下苦功去练。学习任何乐器都是这样，所以幼儿学习小提琴，家长不下决心是不行的。 至于他们学习音乐的能力及自制力，一般说来孩子间都相差无几。在教学过程中发现儿童的初期学习是相差不多的，但后来某些儿童掉队了，其中的原因大约有三种情况: 一是不能坚持练琴。开始学琴时大家兴趣都很高，但由于在短时间内接触不到旋律曲调，再加上一些要求较为严格，不易做到，比如夹琴、持琴、辨音准等，使儿童产生一种厌倦感，兴趣减少，练琴也就不积极了。 二是练琴过程中发生的一些具体情况得不到妥善处理，影响练琴的效益。如儿童练琴中手臂酸了，在练琴过程中常伴有发问、喝水、上厕所等情况，家长容易产生不耐烦的心理，从而使练琴的效益不够理想。 三是由于工作原因而无法督促孩子练琴。大多数儿童的自制力较差，练琴时需要家长们督促，而某些家长由于工作繁忙无暇督促自己的孩子。这也是使孩子“掉队”的一个原因。 以上三点都是幼儿学琴时易遇到的问题，而要解决这些问题，家长首先要有耐心。学习中应尽量少走弯路，但也不能急于求成，欲速则不达～老的传统教学方法正在逐步改变，但也需要有科学的进程。华而不实是不足取的，应从基本功入手，这是每个家长应该与教师配合的。 至于第二点，是在初学过程中发生的正常现象，问题就在于如何引导。一个3、4岁的孩子，在开始练琴几分钟后就应稍做休息，这是他本身的需要决定的。家长可以在这短暂的几分钟休息时间内，鼓励他不要怕艰苦，学习要认真、努力等。然后再逐渐增加时间到一节课为止，要随时保护他的“积极性”，从正面引导入手。如果孩子在练琴时提出了无关的问题，可以要求他先把课堂内容练好，下课再给予答复(要真的给予答复)，并告诉他上课不许讲与课内无关的事，这是课堂纪律，并要求注意力要集中。这既可以很好地解决孩子的问题，同时也不会伤害孩子练琴的积极性。 至于一些琐碎的事情，可以要求孩子在练琴前先做好，从而逐步改变他的练琴习惯，每天的练琴时间最好固定且准时开始，有意识地在纪律、时间观念、注意力等方面培养锻炼孩子。注意要求孩子在轻松的情况下练琴，启发他的好奇心、求知欲，增加他对练琴的兴趣:a special tool to measure half a point the rotor shaft runout and simultaneous measurement of two coupling flutter testing, it should meet the requirements.
