木受绳则直,金就砺则利,君子博学而日参省乎己,则知明而行无过矣。 木受绳则直～金就砺则利～君子博学而日参省乎己～则知明而行无过矣。 ——荀 况 新课程改革向每一位教师提出了做科研型教师的要求，要求教师将新课程的理念理论与自己的教学实践相结合，上好每一节家常课，并在实践和反思中不断进步，达到切实提高教学质量的终极目的。舞台课之于家常课，如木之受绳，金之就砺，因此，“家常课如何学习舞台课”是一个很值得探讨的问。 一、家常课和舞台课的概念认识 家常课指那些非准备过度，没有观众，没有外力援助，一切均在自然状态下进行的课;舞台课指在公开场合进行的，展示优秀教师教艺，供老师们学习探讨的课，由于一般在舞台上进行，故称其为“舞台课”(不包括以评奖为主要目的的评比课)。 二、家常课和舞台课的差异表现 从家常课和舞台课的概念中我们可以看出两者的主要区别在于上课目的和上课环境的不同，这种区别导致的差异主要表现为以下几点。 1、师生心态不同 作为教师，深知上好舞台课的重要性。一方面，上好课可以给老师们更多的感悟启迪，提供更好的学习借鉴的素材，起到引领作用;另一方面，每个人都有将自己最好的一面展示给他人的倾向，且可以提高自己在同行中的评价，所谓“十年讲台无人问，一课成名天下知”，其功利性是不言自明，难以摆脱的;另外，对于一些收费性质的舞台课活动，课的质量好坏直接影响教师对活动质量的评价，会对教师心态产生间接的影响。以上种种，都给教师带来莫大的精神压力，初上舞台的老师常有这样的体会:一杯接一杯地大口喝水依旧口干舌燥，一次又一次地自我鼓励依然两腿哆嗦。除非天才，未经数次磨砺，断难心如止水。家常课则没有上述的压力，教师心态相对平和一些，随意一些。 对学生而言，首先置于众目睽睽的舞台上，注意力一般比家常课要来得集中;其次，初生牛犊不怕虎，加之现在的孩子大多有较强的表现system troubleshooting.

Medical treatment building, aerial parts of each layer on the rehabilitation floor weak current equipment set up between two 2 m network equipment cabinet, assigned to internal and external network devices. basement underground two-level shared network equipment rack. Medical treatment building intranet and extranet communication optical cable from the medical information room of the building leads, along the medical floor weak current tube into each layer individually weak current equipment. Recovery building intranet and extranet communication optical cable from medical and rehabilitation of ground floor one floor basement corridor into the rehabilitation floor weak current lines1th, floor and 2nd, floor of intranet and outside network of communications cable since medical integrated floor of information room leads, along rehabilitation center of weak tube respectively into 1th, floor of East, in the, West three seat floor a layer of weak equipment 了哪些新知识,4、我还有哪些知识不明白,等四个问题来串联教学，渗透学法，效果极佳。听课者若细细品味，定能获益非浅。 求御学生之术。当关注名师在如何调动学生的积极性，在如何引导学生积极思维;当关注名师如何处理师生、生生之间的关系，协调强势群体和弱势群体之间的矛盾;当关注名师如何组织小组合作，如何获得教学反馈等细节。还要有思考后择优而从之的过程，如朱乐平老师多次谈到他喜欢提出一个问题后，学生的表现是静静的，一两分钟甚至几分钟后有那么一只两只小手慢慢地举起来，然后多起来„„这在强调教师要注重学生独立的数学思考的过程，给予他们充分的时间，是十分必要的。但若每每如此，会不会影响差生的学习情绪呢,这需要靠什么来弥补呢,求术路上需要我们的不断思考。 求御课堂之术。如体会哪些是课堂教学的“公共性话语”，哪些是课堂约定俗成的潜;如学习名师是如何面对学生中的生成，如何处理课堂上的突发事件等等。 如特级教师朱乐平老师那“等待”的艺术、“踢皮球”的艺术很值得我们学习。在课堂上，他常常有点“聋”，也常常有些“傻”，但却是个“善球者”。他常常笑眯眯地对孩子们说:“我没有听明白，你听明白了吗,”“哦，我有点明白了，谢谢你，谁还能再帮帮我,”一堂课少者十几次，多则几十次。他评价老师的时候很有水平，但评价学生的时候却实在“笨”，在这个“又聋又傻”的老师面前，不正是孩子们展现自己聪明才智的好机会吗,于是学生探究思考过程就会大胆地展现出来，不同的思考也能碰撞出激烈的火花来，自尊、自信、合作、包容等多种优秀品质得到培养和熏陶，学生的个性获得自由驰骋的广阔天地。我们或许学不得如此炉火纯青，也至少能让课堂多一份生气。 六、家常课如何接轨舞台课 舞台课的目的在于引领和带动家常课走向新课程，但要大面积提高教学质量，就要靠每位教师上好家常课，这是新课程改革是否能真正意system troubleshooting.

Medical treatment building intranet and extranet communication optical cable from the medical information room of the building leads, along the medical floor weak current tube into each layer individually weak current equipment. Recovery building intranet and extranet communication optical cable from medical and rehabilitation of ground floor one floor basement corridor into the rehabilitation floor weak current lines1th, floor and 2nd, floor of intranet and outside network of communications cable since medical integrated floor of information room leads, along rehabilitation center of weak tube respectively into 1th, floor of East, in the, West three seat floor a layer of weak equipment 进绳圈，体验集合的意义，学生感受深刻，思维活跃，理解透彻，实为经典之作。我将其复制粘贴到家常课上，同样取得了极佳的效果。如此好事，何乐而不为之～ 2、择适者而用之 由于教师个体之间以及学生基础的差异，舞台课的适用程度也是不同的，我们应联系实际，择适者而用之。 如在剡山小学教研节活动中，听了三堂《分数的意义》的课，就贴近家常课易于模仿的程度而言，由近到远、从易到难依次为:刘永宽版、钟麒生版、唐彩斌版。结合我个人的喜好，个人所能达到调控课堂的水平，学生的学习起点和学习习惯等因素，我会选择钟麒生版，理由有三:其一为教具易于准备，八枚棋子随手可得;其二为既具一定的创造性和开放度，又与课本知识联系紧密，容易找到与家常课的结合点;其三为改造成家常课较为容易，学好关于八枚棋子的例题后，我可以适当调整一下钟老师的设计，让学生看书自学，再完成课后练习，应该是既轻松又有效的。 值得提醒的是，在选择使用的过程中不忘加入自己的创造，如上述对钟麒生老师课的适当调节。 3、从模仿到原创 从模仿到原创是家常课接轨舞台课的最高境界，也是我们观摩舞台课的最终目的。从模仿到原创是一个由表及里的过程，从对外在的形式、内容的模仿，逐步走向对精、气、神的本质的模仿，是一个从“形似”到“神似”的过程，厚积而薄发，举一而反三，就形成原创;从模仿到原创是一个从量变到质变的过程，在不停的模仿中，融入自己的思考和创造，再在实践中反思提高，将名家精华内化为自己的东西，当自己的思考占据主要位置时，就质变为原创。正如爱因斯坦所说:把学了的东西忘记后剩下的就是素质。这种蜕变，如佛家的“面壁十年，一朝顿悟”，是一个意会的过程，似乎无法以例释之。 system troubleshooting.
