  • 人教版高中历史必修1鸦片战争说课稿2篇

    “第二次鸦片战争”爆发的原因的讲析,可通过出示英国在鸦片战争后在中国与洪都拉斯的正当贸易对比表,让学生观察和创设情景来得出结论。战争的经过及影响,可以通过两次鸦片战争形势图,以及一张相关的表格,从战争的根本目的、性质、过程及影响等方面来比较两次战争的异同,从而让学生理解掌握“战火再燃”其实就是中英鸦片战争的继续和扩大。并理解“第二次鸦片战争”的如何使中国社会半殖民地半封建化的程度大大加深了。并突出英法两国殖民者在占领北京期间所犯的滔天罪行。3、结:结合板书设计,让生自己总结这节课所学的内容,并通过课后习题练于讲相结合,来巩固本课知识。在此基础上对本课线索及主要知识点进行简要的梳理。4、课题延伸:教材后探究学习总结中的一段材料,即《英国驻华商务监督义律致英国外交大臣巴麦尊的机密件》,让学生究义律对中国发动鸦片战争原因的说辞来展开探讨,启发学生运用辨证唯物主义的基本观点,澄清和批驳在在一问题上的一些错误和谬论,从而提高学生辨别是非的能力和批判的能力.

  • 人教版高中生物必修1细胞增殖说课稿

    f.有丝分裂的意义(讨论分析教学),首先引导学生结合所学知识讨论有丝分裂的的作用,最后有教师归纳总结,并要求学生在理解的基础上记忆。g.无丝分裂(图形直观教学、简介),本部分内容不是教学的重点,内容也相对简单,所以我的教学方法是直接给学生展示挂图,再进行简短介绍,让学生了解即可。h.引出减数分裂的概念,为第五章学习打下基础。小结:新课讲完以后由教师对本节内容进行总结巩固和反馈:进行一些课堂练习达到巩固和反馈的作用。最后布置作业,各种难度的作业题目均设置一些,其中简单题比重大,难题要求学生选作,这样提高学生学习积极性。2教学媒体程序设计: 细胞周期的概念(多媒体课件演示周期动画)植物细胞有丝分裂(多媒体课件演示分裂各期动画)动植物细胞有丝分裂异同点(多媒体课件演示分裂各期动画)有丝分裂过程中DNA和染色体数量的变化规律(挂图演示,包括表格和函数图象)

  • 人教版高中生物必修1细胞的衰老与凋亡说课稿

    4、最后从生物的寿命引入,探讨细胞的死亡。强调细胞死亡有两种形式。(1).细胞坏死,它是由某些外界因素造成细胞急速死亡,是一种被动性死亡;(2).细胞凋亡,这是一种由特定基因控制的主动性死亡。细胞坏死与细胞凋亡在形态学和生物化学上有着明显的区别。细胞凋亡有广泛的生物学意义,比如胚胎发育期手的发育如果没有细胞的调亡就不会有纤细的手指;如果没有正常的细胞调亡,蝌蚪的尾部就不会消失,它将永远不能变成青蛙……。正常的细胞调亡还肩负着维持各种组织器官固有体积和形态的功能;还会使机体内异常的细胞得到及时清除,去处潜在的隐患;例如癌症就是异常的细胞没有及时死亡的结果……。因此细胞的正常死亡是生物体的一种非常重要的调节机制,是机体平衡细胞增殖,调节机体细胞树木恒定的方式,是必不可少的生命过程。(15分钟)5、课堂小结,可以把课堂传授的知识尽快地转化为学生的素质;简单扼要的课堂小结,可使学生更深刻地理解政治理论在实际生活中的应用,并且逐渐地培养学生具有良好的个性。

  • 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兼顾效率与公平说课稿

    (3)如何做到兼顾效率与公平?这部分知识点我结合上面的图片,设疑:“请大家对这一社会现象进行讨论,我们如何才能做到既坚持效率又兼顾公平?”导入这部分的分析。学生在讨论的过程中对如何兼顾效率与公平已经形成了一定的见解,结合图片,为兼顾效率与公平献计献策,寻求两者的最佳结合点。幻灯片展示:怎样才能做到兼顾效率与公平?第一,允许和鼓励一部分地区和个人通过诚实劳动和合法经营先富起来,带动其他地区和个人致富,最终达到共同富裕。第二,既要反对平均主义,又要防止收入差距悬殊。既要落实分配政策,又要提倡奉献精神;在鼓励人们创业致富,提倡回报社会和先富帮后富。第三,必须正确处理初次分配注重效率与再次分配注重公平的关系。在讲授过程中,还展示大量图片。结合图片分析。设计意图:体现课堂上学生的主体地位,让学生在观看中体验,在讨论中升华,从而体会构建和谐社会的重要意义。

  • 人教版高中政治必修1股票与债券说课稿

    一、说教材(一)说教材的地位和作用《股票、债券、保险》是人教版必修1《经济生活》第六课,第二框题的内容。本框题承接前面“企业与劳动者”:企业的发展资金从何而来,同时又为下一课“个人收入与分配”做好了铺垫,它在整个教材中起承上启下的作用。因此,本框题在《经济生活》中具有不容忽视的重要的地位。(二)说教学目标根据高一新课程标准要求,本教材的结构和内容分析,结合着高一年级学生的认知结构及其心理特征,我制定了以下的教学目标:1、知识目标(1)股票的含义、收益、特点和发展股票市场的意义。(2)债券的含义与分类(3)商业保险的含义与订立原则2、能力目标(1)重点培养学生辩证思维的能力,发现和分析、解决问题的能力。3、情感、态度与价值观目标培养科学理财的意识,形成“投资理财,利国利己”的观念。(三)说教学的重、难点本着高一新课程标准,在吃透教材基础上,我确定了以下的教学重点和难点

  • 人教版高中政治必修1市场配置资源说课稿

    (2)、市场调节存在固有的弊端:自发性:由于市场调节是在价值规律自发作用下进行的,在利益驱动下会产生一些违反市场原则的行为,如制造、销售假冒伪劣商品,大量排放废水、废气破坏环境,窃取他人智力成果等等。盲目性:由于人们不可能完全掌握生产各方面信息及其变化趋势,致使决策带有一定的盲目性。如某种商品有利可图则一哄而上,反之则一哄而退,从而造成资源浪费和消费得不到充分满足。滞后性:由于市场价格的形成和传递有一个过程,一旦传递到生产经营者手中进行生产调整,就有一个时间差,致使市场调节带有滞后性,成为一种事后调节。教师活动:请同学们想一想,市场的这些弊端和不足,会导致什么后果?(3)、危害教师总结:资源浪费,经济波动与混乱,分配不公两极分化等。设计意图:通过创设情景,加深对市场调节局限性的理解;要求学生结合生活实例探讨其弊端有助于加强对其产生原因和表现的记忆和理解。
