    (1观察图解,色盲基因在性别间是如何传递的呢?(女--女、女--男、男--女)(2)为什么不能由男性传给男性?(色盲基因是在X染色体上,因此色盲基因是随X染色体的传递而传递。)(3)男性的色盲基因怎样才能传给男性呢?(通过女儿,传给外孙即交叉遗传)(4)从图解看色盲在男女中的发病情况怎样?(男性多于女性)(5)从社会调查也是这样,你是否能从基因和染色体的角度加以解释?(提示:女性染色体的构成,结合基因位置及显隐性进行分析)归纳特点:归纳出色盲基因遗传的特点并扩展到X染色体隐性遗传的特点上。色盲基因遗传(X隐性遗传)的特点:(1)男患者多于女患者(2)交叉遗传(3)女病儿子必病,男正女儿必正等。问题探讨:利用“遗传图解”结合“问题链”继续探讨,拓展到抗维生素D即X 染色体显性遗传的特点。(6)色盲基因在X染色体上属隐性基因,子代表现男多于女,对应的正常色觉基因则属于X显性基因,子代表现应如何?(女多于男)

  • 人教版高中生物必修2染色体变异说课稿

    四、说教学程序(一).温故知新、导入新课复习提问:基因突变导致生物变异的原因是什么?回答:基因突变是基因结构发生改变,从而使遗传信息改变,使蛋白质结构改变、生物性状改变,即生物发生了变异。那么,基因是什么?它和染色体又有何关系?回答:基因是有遗传效应的DNA片断,染色体是DNA的载体,基因在染色体上呈线形排列。引出新知:对于一个生物体来说,正常情况下,其染色体的结构和数量都是稳定的。但在自然条件或人为因素的影响下,染色体的结构和数量均会发生改变,从而导致生物性状的改变,这就属于染色体变异。(二).把握重点、突破难点重点的把握:1、染色体结构的变异播放影片:猫叫综合征幼儿。让学生观察: 患儿哭声轻、音调高,很像猫叫。教师补充: 患儿的征状---两眼较低、耳位低下,存在着严重的智力障碍。阐述病因---染色体片段缺失

  • 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。

    环节三 案例分析 突破难点我将用多媒体展示两组反映中学生参与民主管理的一些作法的图片,和教材26-27页的三个镜头,然后请同学们根据图片和材料探究以下问题: 1. 联系自身实际谈谈这些做法对我们有何启示? 2.实行农村村民自治和城市居民自治有什么意义呢? 3. 我们在实际生活中应怎么做?这样,通过图片和材料的展示,点明了公民参与民主管理的意义,以此来诱发学生已有的真切体验,感受其境,增强学生共创想和文明社区的积极性和情感。同时,我们也希望学生在学习本课的知识后,又能做到学以致用,把所学的知识真正用到社区管理中,为所在社区管理提合理建议,从而真正实现了知识从生活中来,又回到生活中去的理念。环节四课堂小结 课后延伸将用多媒体展示本节课的知识框架,并注重引导学生将今天所学新知识与前面知识联系起来,帮助学生从宏观上把握各知识点之间的关系,有利于学生理解记忆,以此来帮助教师在第一时间掌握学生学习信息的反馈,同时培养学生归纳分析能力、概括能力。

    二、学生情况分析(说学法)1、学生学习基础分析:学生通过对《生活与哲学》前面三个单元的学习,初步掌握了运用唯物论、辩证法、认识论的观点去认识问题、分析问题的能力;再通过对第十一课的学习,学生对马克思主义的历史观有了初步的理解,初步树立了正确的理想信念,这为本课教学目标的落实奠定了知识基础。 2、学生能力分析 :高二学生拥有一定生活体验,具备一定的信息收集和筛选能力、阅读能力、语言表达能力、对问题的一定的探究能力,同伴合作能力和具备初步逻辑思维能力。3、学生心理分析:在我国现阶段,以为人民服务为核心的社会主义道德建设过程中涌现了大批的先进人物和道德典范,但同时由于社会价值的多元化,个人主义、享乐主义、拜金主义等资本主义腐朽思想也同样在影响着当代的中学生。

    (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。主要通过几幅漫画让学生思考其中的哲学道理,开始接触哲学。漫画一:种瓜得瓜,种豆得豆,种鸡蛋得??漫画二:甲:下雨好极啦!乙:下雨糟透了!漫画三:——狂妄之徒,你竟然坏了祖上规矩!在引导学生思考、体验问题的过程中,可以使学生逐步学会分析、解决问题的方法。这样做既有利于发展学生的理解、分析、概括、想象等创新思维能力,又有利于学生表达、动手、协作等实践能力的提高,促进学生全面发展,力求实现教学过程与教学结果并重,知识与能力并重的目标。

  • 人教版高中历史必修2罗斯福新政说课稿2篇

    1、教材的地位作用本课是新人教版普通高中历史必修Ⅱ第六单元第18课的内容,阐述罗斯福新政的背景、措施、影响。从单元知识安排看,本课与第17课《空前严重的资本主义世界经济危机》、19课《战后资本主义的新变化》共同诠释第六单元课题——《资本主义世界经济政策的调整》。说明了“资本主义经济理论和政策随着资本主义发展而不断调整的特点”,凸显了“市场调节”和“国家干预”在经济发展中的重要性。从知识体系看,它是学生学习了第一次工业革命后自由资本主义、第二次工业革命后的垄断资本主义等之后出现的,既是对上述知识的巩固与综合运用,又为学生学习必修二的相关内容打下基础,有承上启下的作用。本课三个子目从逻辑上看又是递进关系。第一个子目“临危受命”承上启下,说明了罗斯福上台的历史背景具有临危受命的特点,第二个子目“实施新政”讲述了罗斯福新政的主要内容,第三个子目“摆托危机困境”主要讲述了罗斯福新政的影响。

  • 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。
