人教版新课标高中物理必修1运动快慢的描述─速度教案2篇
生：还可以从表盘上直接读出公里里程．师：日常生活中的“速度”有时指速度，也有时指速率，要看实际的物理情景。[讨论与交流]甲、乙两位同学用不同的时间围绕操场跑了一圈，都回到了出发点，他们的平均速度相同吗?怎样比较他们运动的快慢?学生讨论，体验平均速度的缺陷，引入平均速率。生1：位移都是零，平均速度等于位移跟发生这段位移所用时间的比值，所以他们的平均速度都是零。生2：即使一位同学站在原地不跑，他的平均速度也是零啊，可我们运动会上不是这样比快慢的，如果这样，那多不公平啊?师：平均速度v=Δx/Δt，甲、乙的位移都为零，所以他们的平均速度也都等于零．在这里平均速度无法显示他们运动快慢的不同，要用到另一物理量：平均速率．平均速率等于物体运动通过的路程跟所用时间的比值．他们两人通过的路程相同且都不为零，但所用时间不同．显然用时短的运动得快，也就是平均速率大．生：这不是我们初中学过的速度吗?
人教版新课标高中物理必修2探究弹性势能的表达式教案2篇
“做功的过程就是能量转化过程”，这是本章教学中的一条主线。对于一种势能，就一定对应于相应的力做功。类比研究重力势能是从分析重力做功入手的，研究弹簧的弹性势能则应从弹簧的弹力做功入手。然而弹簧的弹力是一个变力，如何研究变力做功是本节的一个难点，也是重点。首先，要引导学生通过类比重力做功和重力势能的关系得出弹簧的弹力做功和弹簧的弹性势能的关系。其次，通过合理的猜想与假设得出弹簧的弹力做功与哪些物理量有关。最后，类比匀变速直线运动求位移的方法，进行知识迁移，利用微元法的思想得到弹簧弹力做功的表达式，逐步把微分和积分的思想渗透到学生的思维中。本节课通过游戏引入课题，通过生活中拉弓射箭、撑杆跳高和弹跳蛙等玩具以及各种弹簧等实例来创设情景，提出问题。给学生感性认识，引起学生的好奇心；让学生对弹簧弹力做功的影响因素进行猜想和假设，提出合理的推测，激发学生的探索心理，构思实验，为定性探究打下基础。然后，引导学生通过类比重力做功与重力势能的关系得出弹簧弹性势能与弹簧弹力做功的关系。
人教版新课标高中物理必修2探究功与速度变化的关系教案2篇
说明：“倍增法”是一种重要的物理方法，历史上库仑在研究电荷间的相互作用力时曾用过此法，但学生在此前的物理学习中可能未曾遇到类似例子，因此引导学生通过交流，领会“倍增法”的妙处，这是本节课的一个要点．可用体育锻炼中的“拉力器”来类比。（2）该方案消除摩擦力影响的方法：所用的消除方法与实验方案2一样。也可使用气垫导轨代替木板，以更好地消除摩擦影响。（3）小车速度的确定方法：①确定打出来的点大致呈现什么规律：先密后疏（变加速），再均匀分布（匀速）；②应研究小车在哪个时刻的速度：在橡皮筋刚恢复原长时小车的瞬时速度，即纸带上的点刚开始呈现均匀分布时的速度；③应如何取纸带上的点距以确定速度：由于实验器材和每次操作的分散性，尤其是橡皮筋不可能长度、粗细完全一致，使得每次改变橡皮筋的条数后，纸带上反映小车匀速运动的点数和点的位置，不一定都在事先的设定点（即用一条橡皮筋拉小车，橡皮筋刚好恢复原长时纸带上的点）处。

人教版高中语文必修5《林教头风雪山神庙》教案
②林冲无辜受害，被刺配到沧州，远离了京城，高俅一伙，陆谦、富安又追到沧州，在李小二的酒店里密谋陷害林冲。林冲从李小二那里听说了这件事之后是什么态度？表现出林冲的什么性格？明确：林冲听到李小二的报信，并确知从东京来的尴尬人就是陆虞候时，马上意识到“那泼贱贼”是要“来这里害我”，他识破了仇人的阴谋，激起了复仇的怒火，气愤地说：“休要撞着我，只叫他骨肉为泥！”说罢，便怒冲冲地“先去街上买把解腕尖刀，带在身上，前街后巷一地里去寻”，次日，“带了刀，又去沧州城里城外，小街夹巷，团团寻了一日”。这说明，当迫害逼到眼前时，林冲也具有了强烈的反抗意识。但是，“街上寻了三五日，不见消耗”时，“林冲也自心下慢了”，对仇人有所怀疑，却失去了应有的警惕性，刚刚点燃起来的复仇怒火又慢慢熄灭了。这说明林冲的反抗并不坚决，幻想得过且过，委曲求全。
人教版高中语文必修5《谈中国诗》教案
教师提示：1.这句话的本体不是一般意义上的“中国诗”，即不是指中国诗歌中的某一类作品或某位诗人的作品，而是指中国诗的发展特点。早熟，是指“纯粹的抒情诗的精髓和峰极，在中国诗里出现得异常之早”；早衰，是指“中国诗一蹴而至崇高的境界，以后就缺乏变化，而且逐渐腐化”(腐化，是对诗的思想内容和艺术价值而言的)。这句话，借助比喻和比喻中的对比(“早熟”与“早衰”)，从诗歌发展的角度，简要地说明了中国诗的艺术特征和由此产生的负面影响。2.这句话有两层意思：一是借梵文的《百喻经》阐释中国的艺术和思想体构上的缺欠，旨在批评；二是点明造成这种缺欠的根本原因。“一个印度愚人要住三层楼而不许匠人造底下两层”这样的建筑物就是“飘飘凌云的空中楼阁”，作者以此作喻，批评中国的艺术和思想体构缺乏严密的逻辑性，往往脱离客观实际，没有坚实的基础，其结果必定影响艺术的健康、稳定地发展。
人教版高中语文必修4《柳永词两首》教案
（一）上片：描写杭州的自然风光和都市的繁华“东南形胜，三吴都会，钱塘自古繁华”，“东南形胜”，是从地理条件、自然条件着笔写的。杭州地处东南，地理位置很重要，风景很优美，故曰：“形胜”。“三吴都会”，是从社会条件着笔写的。它是三吴地区的重要都市，那里人众荟萃，财货聚集，故曰：“都会”。“钱塘自古繁华”，这一句是对前两句的总结，因为杭州具有这些特殊条件，所以“自古繁华”。下面就对“形胜”、“都会”和“自古繁华”进行铺叙。“烟柳画桥，风帘翠幕，参差十万人家”是对“三吴都会”的展开描写。“云树绕堤沙。怒涛卷霜雪，天堑无涯”是对“东南形胜”的展开描写。这里选择了钱塘江岸和江潮两种景物来写。“市列珠玑，户盈罗绮，竞豪奢”是对“钱塘自古繁华”的展开描写。描写了两个方面：一是商业贸易情况——“市列珠玑”，只用市场上的珍宝，代表了商业的丰富、商业的繁荣；二是衣着情况——“户盈罗绮”,家家披罗着锦。“竞豪奢”，又总括杭州的种种繁华景象。
