人教版高中生物必修2伴性遗传说课稿
（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1细胞的癌变说课稿
5．5癌症的预防作为本节最重要内容，且与生活息息相关，我采用老师引导、学生讨论总结的方法进行教学。从生活各方面总结出保健良方 ，既对知识有很好应用，又体现对生命的热爱。此时，本节课达到高潮，同学们意气风发，热烈讨论，实现本节课的教学目标。5．6 癌症的治疗通过讲述癌症治疗方法的副作用，激发学生探究生物学欲望，激励学生立志除癌。 在此，我选用一则关于一名癌症晚期病人运用心理疗法成功战胜癌症的故事，在于对不同层次的学生进行多方面启发教育，体现面向全体学生的课程理念。5．7 愉悦总结，及时反馈本节知识点零散，我将带领学生回忆浏览本节内容，使零散知识点系统化。在课堂反馈环节，我通过简单练习采用分组竞答的方式把握学生对知识的掌握程度，并给予表现突出的学生适当奖励，这是本节课第三个亮点。竞答既使课堂显得紧凑、集中，又有利于形成学生的竞争意识，还使得学生的知识得以巩固应用。
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。
人教版高中生物必修2DNA的复制说课稿
设问：DNA复制后两个子代DNA分子与亲代DNA分子是否完全相同？为什么？通过设问，让学生进一步理解和巩固DNA复制的全过程。接下来让学生总结出DNA复制的四大基本条件：① 模板：开始解旋的DNA分子的两条单链；② 原料：是游离在核液中的脱氧核苷酸；③ 能量：是通过水解ATP提供；④ 酶：酶是指一个酶系统，不仅仅是指一种解旋酶。最后通过以上分析，总结出DNA复制的意义以及在生活中的应用：意义：DNA通过复制，使遗传信息从亲代传给子代，从而保证了物种的相对稳定性，保持了遗传信息的连续性，使物种得以延续。应用：目前DNA分子广泛应用于刑事案件侦破等方面：如：DNA分子是亲子鉴定的主要证据之一。把案犯在现场留下的毛发、血等进行分析作为破案的证据，与DNA有关。五、设计课堂练习：设计一题典型课堂练习：即有关半保留复制及计算的习题：

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。
