  • 人教版高中地理必修1全球气候变化教案

    科学家预测,就地区而言,位于低纬度的大部分国家,农作物的产量将减少;而位于高纬度的国家,农作物产量有可能增加。由于不少发展中国家位于低纬度地区,因此,气候变化的这种区域差异性,可能会使发展中国家所面临的问题更为严峻。板书:3全球变暖将加剧水资源的不稳定性与供需矛盾。介绍:全球变暖会影响整个水循环过程,可能使蒸发加大,改变区域降水量和降水分布格局,增加降水极端异常事件的发生,导致洪涝、干旱灾害的频次和强度增加,以及地表径流发生变化。随着径流减少,蒸发增强,全球变暖将加剧水资源的不稳定性与供需矛盾。转折:既然全球变暖会引起很多不利影响,那么作为人类应如何面对这一挑战呢?这就是我们要讨论的第三个问题。板书:三、气候变化的适应对策讨论:请大家阅读结合教材P53气候变化的适应对策部分讨论人类应如何面对全球变暖这一问题 呢?

  • 人教版新课标高中物理必修1弹力教案2篇

    一般情况下,凡是支持物对物体的支持力,都是支持物因发生形变而对物体产生弹力。所以支持力的方向总是垂直于支持面而指向被支持的物体。例1:放在水平桌面上的书书由于重力的作用而压迫桌面,使书和桌面同时发生微小形变,要恢复原状,对桌面产生垂直于桌面向下的弹力f1,这就是书对桌面的压力;桌面由于发生微小的形变,对书产生垂直于书面向上的弹力f2,这就是桌面对书的支持力。学生分析:静止地放在倾斜木板上的书,书对木板的压力和木板对书的支持力。并画出力的示意图。结论:压力、支持力都是弹力。压力的方向总是垂直于支持面而指向被压的物体,支持力的方向总是垂直于支持面而指向被支持的物体。引导学生分析静止时,悬绳对重物的拉力及方向。引导得出:悬挂物由于重力的作用而拉紧悬绳,使重物、悬绳同时发生微小的形变。重物由于发生微小的形变,对悬绳产生竖直向下的弹力f1,这是物对绳的拉力;悬绳由于发生微小形变,对物产生竖直向上的弹力f2,这就是绳对物体的拉力。

  • 人教版高中历史必修1甲午中日战争说课稿

    3.甲午中日战争中国战败的原因 对于“中国战败的原因”这一难点的突破,主要通过设置问题“中国之败败在实力逊于日本吗?”通过幻灯片全方位分析其实中国的综合国力当时是强于日本的。并且在战前,日本毫无取胜的把握。让学生结合刚学习过的战争原因和经过进行讨论,从多方面分析中国战败的原因。经过讨论,学生可以得出以下结论:避战自保方针,没有积极备战,将领临阵脱逃,教师肯定并总结答案进行补充。中日对比:中国士兵出身农民,军事训练落后,散兵游勇;日本士兵出身武士,训练有素;中国将领大多临阵脱逃,并相互猜忌,受当时恶劣的官风影响;李鸿章深知北洋海军实情,缺乏军费,军备废弛。为政治资本奉行避战自保政策,慈禧太后挪用海军军费过寿,支持李鸿章。使中方处于被动的局面,一再贻误战机。而日本在天皇的带动下,全民备战,做了充分的战争准备。

  • 人教版高中生物必修1细胞分化说课稿

    在讲述细胞分化的意义时,也可以用实例来解决,工厂的生产车间里不同的工人干着不同的工作,一件产品的产出需要这些工人才能创造出来,一个生物体就像一个车间一样,不同的细胞各司其职,相互合作。工人的分工是主管调解出来的,而不同细胞的出现就是细胞分化的结果,所以说,细胞的分化是生物体发育的基础。在讲到细胞全能性的时候,要多给学生举些关于细胞全能性的例子,如植物组织培养、克隆技术等等,让学生从实际的例子中真正的悟出细胞全能性的含义。此外,还要重视教材中的疑问,适当对题目进行引申,使它的作用更加突出,有利于学生对知识的串联、积累、加工,从而达到举一反三的效果。怎样来解释细胞的全能性呢?这主要以讲授法来解释了,细胞全能性的体现需要在组织或器官离体后才能体现出来,每个细胞都包含着生物体的全套遗传基因,通过基因选择性的表达,使离体的组织或器官通过分裂和分化逐渐发育成完整的植株。

  • 人教版高中政治必修1信用工具和外汇说课稿

    一、对教材内容的处理根据新课程标准的要求、知识的跨度、学生的认知水平,我对教材内容有增有减。二、教学策略的选用(一)运用了模拟活动,强化学生的生活体验,本框题知识所对应的经济现象,学生已具有了一定的生活体验,但是缺乏对这种体验的深入思考。因此在进一步强化这种体验的过程中进行了思考和认知,使知识从学生的生活体验中来,从学生的思考探究中来,有助于提高学生的兴趣,有助于充分调动学生现有的知识,培养学生的各种能力,也有助于实现理论知识与实际生活的交融。(二)组织学生探究知识并形成新的知识我从学生的生活体验入手,运用案例等形式创设情境呈现问题,使学生在自主探索、合作交流的过程中,发现问题、分析问题、解决问题,在问题的分析与解决中主动构建知识。也正是由于这些认识来自于学生自身的体验,因此学生不仅“懂”了,而且“信”了。从内心上认同这些观点,进而能够主动地内化为自己的情感、态度、价值观,并融入到实践活动中去,有助于实现知、行、信的统一。

  • 人教版高中政治必修1税收及其种类说课稿

    在学生明确了税收的含义之后,我将分别对税收的三个基本特征进行解析。在讲解了之后,并分别用实例对其进行说明,加深学生对知识点的印象。最重要的是,总结出关键的字眼,使得学生能够清晰的区分出税收的三个基本特征。将强制性概括为依法征税、依法纳税;无偿性概括为不具有偿还性和返还型;固定性概括为规定应不应纳税、纳什么税、纳多少税。并跟学生指出,强制性是基本前提,无偿性是核心。由此根据书上的内容,推导出税收的三个基本特征相互之间的关系,即:三者缺一不可,统一于税法。而且,无偿性要求强制性,强制性保障无偿性;而无偿性与强制性又共同决定固定性。从而结束新课讲授。3、课堂总结根据板书内容重新回顾本课学习的主要内容,包括税收的含义,以及税收的三个基本特征和它们之间的相互关系。4、作业布置让学生预习税收的种类的内容,尤其是增值税和个人所得税。同时了解父母每月所缴纳的个人所得税和怎么计算的。
