说课稿结束语【第一篇】
一年一度的寒假生活即将到来,在寒假中,为了加强幼儿的安全防范意识,保障幼儿的身心健康,确保幼儿的安全,让幼儿度过一个安全快乐的假期,特此设计此教学。
1、认知目标:通过观看课件让幼儿懂得安全的重要性。
2、能力目标:提高安全意识和自我保护能力。
3、情感目标:引导幼儿乐于探索、交流与分享,激发兴趣。
重点:通过观看课件学习假期安全的相关知识。
难点:通过学习提高幼儿的安全意识和自我保护能力。
有关交通安全、防溺水安全、燃放烟花爆竹等相关课件。
直观法、谈话法六、说教学活动设计教学活动:
(一)假期中的打算谈话引入,小朋友们,我们的寒假生活即将到来,老师想了解一下放了假你们想做些什么事情呢?教师引导幼儿说出自己想做的或是喜欢做的事情(教师要鼓励幼儿大胆表述)
教师小结:刚才小朋友们说出了许多假期中的打算,但是无论小朋友们做什么事情都要时刻注意安全。
教学活动:
(二)组织幼儿探讨怎样快乐地度过假期在这一活动中,通过前面幼儿说出怎样来玩,教师进一步引出我们在做这些事情时应怎样保护自己?(教师引导幼儿互相说一说)这一环节可以培养幼儿的表达能力。
教学活动:
(三)教师总结幼儿假期中应注意的安全主要从以下四个方面来讲安全:交通安全、防溺水安全、电方面的安全、火的安全。
1、教师出示有关交通安全方面的课件,引导幼儿观看,随之教师小结在交通安全上应注意:
(1)自觉遵守交通规则,不在公路上跑闹、玩耍;
(2)不得独自横穿公路,要有大人的陪同;
(3)文明乘车,在车内不随便扔果皮,更不能把头伸出车窗外。此环节可以增强幼儿的交通安全意识。
2、课件出示溺水事故片段,引导幼儿仔细观看,教师再小结在防溺水安全方面应注意:
(1)小朋友严禁到水库、池塘、河流等戏水、打捞东西,不能独自或结伴到池塘边、河流、玩水、滑冰。
(2)如果发现有小朋友不慎掉进水库、池塘、水井等,我们不能擅自下水营救,应大声呼成年人来相助或拨打"110"
3、老师引入电方面的安全在此环节中让幼儿想一想有哪些家用电器,我们要不要随便触摸家用电器,引导幼儿说出不能随便触摸家用电器受伤,尤其是电线、灯头、插座等。
4、老师出示小朋友放烟花爆竹的图片,进一步引出火的安全。
(1)不能私自燃放烟花爆竹,避免失火或受伤。
(2)不准玩火,不得携带火种,以免发生火灾,发生火灾时及时拨打"119"。
(3)冬季做好煤气中毒预防工作。

说课稿结束语【第四篇】
各位领导老师好
我今天说课的内容是免疫调节,下面我将从教材分析、教法和学法、教学设计、板书设计等几个方面来对本课题进行说明。首先我对本课题的教材进行分析,随着课改的进行,新课标将免疫调节列为必修三第2章的重要内容,从内容看,神经体液免疫共同完成人和高等动物生命活动的调节,对维持人体内环境的稳态有重要的作用。同时本节内容又与日常生活密切联系,并且近几年高考中时有出现,因此,学好本节课意义重大。
基于对教材的理解和分析,我从知识、能力、情感三方面确定了如下的教学目标。首先知识方面,我认为学生应该掌握免疫系统的防卫功能,理解体液免疫和细胞免疫的过程以及两者之间的关系。其次能力方面,要培养学生的比较归纳和自主学习的能力;再次情感方面就是要学生关注自身健康,珍爱生命,确立积极的生活态度和健康的生活方式。
在吃透教材的基础上,结合学生的认知结构,我制定了本课的重难点:重点是免疫系统第三道防线的防卫功能,难点就是体液免疫和细胞免疫的过程及其关系。
下面我再从教法和学法上谈一下,我准备采用讲解法:归纳法:图示法:比较法等教学方法达到教学目标。学生通过初中有关免疫知识的学习,对人体的三道防线有了初步的认识,但对免疫调节的了解还是很浅。因此,教学中可以充分利用学生已有的知识,通过适当的教学策略,使新知识有效地整合进学生原有的知识体系中,具体的用到:主动学习法:让学生自主观察流程图,并尝试提出问题;比较归纳法:比较两种免疫的不同,归纳出特异性免疫的具体步骤。
我将具体说一下本次说课的第三部分—教学设计,我将分为如下几个环节
联系学生已有的知识,创设问题情景——我们的身体被大量的病原体包围着,1、病原体侵入机体后,会影响内环境的稳态吗?
2、人体靠什么来消除病原体对内环境的影响呢?通过创设问题情景,激发学生的探究欲望,主动地参与学习过程,从而导入新课——人体的免疫调节
进入第二环节,创设情景,讲授新课
①利用课件展示,学生讨论人体有哪些途径来抵御病原体的攻击。通过自主学习总结出人体免疫系统的三道防线,让学生体验到自主学习的成功。并提出新问题:第三道防线如何产生抗体?抗体又是如何发挥作用的?激发学生的探究欲望,积极参与教学过程。
②引导学生分析得到结论:抗体是机体受抗原刺激后产生,并与抗原发生特异性免疫的球蛋白。抗体分布在体液中,所以这种免疫称为体液免疫.进一步提出问题:产生抗体的主要路径有哪些?记忆细胞对身体的免疫具有什么意义?
③有些微生物如病毒和细菌是寄生在宿主细胞中,而抗体是不能进入宿主细胞的,那么机体如何消灭这些病原体呢?通过多媒体展示细胞免疫过程,提出新的问题:t细胞和效应t细胞的关系以及作用,最终消灭病原体的是什么?细胞免疫和体液免疫是否独立?它们有什么关系?通过这些问题的设置,将复杂的问题简单化 将抽象的过程系统化,将知识提升为学生的技能
④然后列出体液免疫和细胞免疫的区别与联系并对免疫系统的组成进行归类
最后,说我的板书设计,也是我说课的第四部分,我将这样设计本课的课堂板书…我认为这样的设计比较直观系统,一目了然。简要体现了教材中的知识点,便于学生理解。
