  • 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。

  • 人教版高中政治必修1新时代的劳动者说课稿

    第一环节:关于劳动光荣和就业的意义。这两个问题学生在自主阅读的基础上,教师设疑,给出两个人物事迹,一是农民工刘俊刚把青春献给第二个家乡的城市美容师;一是北大学子李彦宏自主创业,创建百度公司,启发学生比较、思考。很多学生倾向于要做李彦宏,教师则适时引导:难道清洁工的劳动不重要吗?经过辩论,归纳出劳动和就业的意义。接着利用教材中李师傅的事例,进行问题探究,“李师傅找不到工作的原因是什么?”从主客观两方面分析,带着问题进入到下一环节学习。第二环节:突出重点。多媒体展示:通过数字的列举及对占有材料的分析,既看到了我国就业形势严峻,也介绍了国家关注民生,实施积极的就业政策。在此基础上,教师启发学生归纳“我国就业严峻的原因及对策?”学生把教材理论与生活中的现实材料相结合,进行探究,得出就业形势严峻的主要原因及其相应对策。

  • 人教版高中政治必修3聚焦文化竞争力说课稿

    (1)文化与经济、政治在经济基础上相互影响。①经济、政治和文化是社会生活的三个基本领域。其中,经济是基础,政治是经济的集中表现,文化是经济和政治的反映。一定的文化由一定的经济、政治所决定,又反作用于一定的政治、经济,给予政治、经济以重大影响。②经济发展是文化发展的基础。但这并不意味着文化的发展始终与经济的发展亦步亦趋。如同不能简单地把精神文明看作是物质文明的派生物和附属品一样,也不能简单地认为文化是经济、政治的派生物和附属品。文化有其自身的传承性和相对的独立性。那种认为只要物质条件好了,精神文化自然而然地就会好起来,物质条件差一点,精神文化就不可能搞好的观点,不符合历史发展的事实,是不正确的。③掀开历史的画卷,文化既有古今和地域之别,又有先进与落后、腐朽之分。不同的文化,对经济、政治的影响不同,对社会发展的作用也不同。不同民族的文化,影响不同民族和国家各具特色的发展道路。
