必修三第二章第1节《通过神经的调节》教案

第二章第1节通过神经系统的调节 一、教材分析:本节内容是生命活动调节的第一节,因此在教材中占据了承上启下的重要的地位。但是本节课内容比较抽象,不直观,学生不易理解。因此要借助多媒体的辅助,观看神经冲动在神经纤维上的传到,及突触间的传递过程。 二、教学目标 1.知识目标: 1.概述神经调节的结构基础和反射。 2.说明兴奋在神经纤维上的传导和在神经元之间的传递。 3.概述神经系统的分级调节和人脑的高级功能。 2.能力目标:能设计关于神经传导方向的实验 3.情感、态度和价值观目标:通过学习用过神经的调节,来体会生命活动调节的准确性,及复杂性 四、学情分析 我们的学生属于平行分班,但学生已有的知识和水平有差距,且本节课内容抽象,特别是兴奋的产生、传导过程,很难理解,最好借助多媒体,动画展示兴奋产生、传导的过程,有利于学生理解。 五、教学方法 1.多媒体动画展示。 2.学案导学:见后面的学案。 3.新授课教学基本环节:预习检查、总结疑惑→情境导入、展示目标→合作探究、精讲点拨→反思总结、当堂检测→发导学案、布置预习 六、课前准备 1.学生的学习准备:预习“通过神经系统的调节”把握神经调节的方式,神经调节的结构基础、反射弧的构成、突触、突触小体等基本概念;初步理解兴奋的产生、传导过程。2.教师的教学准备:多媒体课件制作,课前预习学案,课内探究学案,课后延伸拓展学案。3.教学环境的设计和布置:两人一组,多媒体教师教学。 七、课时安排:1课时 八、教学过程 (一)预习检查、总结疑惑 检查落实了学生的预习情况并了解了学生的疑惑,使教学具有了针对性。 (二)情景导入、展示目标。 导入:利用教材P16[问题探讨]导入新课 我们来看本节课的学习目标。多媒体展示学习目标,强调重难点。然后展示探究的问题,已经布置学生们课前预习了这部分,检查学生预习情况并让学生把预习过程中的疑惑说出来。 (三)合作探究、精讲点拨。 探究一:神经调节的结构基础和反射 教师设置下列问题引导学生讨论和思考: ⑴人和动物各器官系统的协调,以及对外界刺激作出反应主要是通过神经系统来完成的,那么神经调节的方式是什么呢? ⑵什么是反射?你能举出几个反射活动的实例吗?草履虫能够趋利避害,含羞草叶被触碰后会下垂,这属于反射吗?如果有人用针刺了你一下,你感到了疼痛,这属于反射吗?用针刺激离体蛙的腓肠肌,肌肉会收缩,这属于反射吗?
