《生活方式与健康》教学设计

指导思想与理论基础：

初中生已有一定的判断对错的能力，但自制力不强，有一些不良的生活习惯，是影响他们健康的隐患。按《中小学健康教育指导纲要》和《初中生物课程标准》设计本节课。本节课《生活方式与健康》通过学生讨论交流和看幻灯等活动，认识生活方式对健康的影响，明确哪些是健康的生活方式，哪些是不健康的生活方式，从而自觉地选择健康的生活方式，改掉不健康的生活习惯。

教学活动背景分析：

初中生但在生活中进积累了一些不良的生活习惯需要通过教育进行校正。他们已有一定的判断能力和知识储备，可以通过讨论交流和看幻灯等活动进行教学，班班通电脑为我们的教学提供了较好条件。

教学目标：

1、认识生活方式对健康的影响。

2、明确哪些是健康的生活方式，哪些是不健康的生活方式。

3、引导学生自觉地选择健康的生活方式，改掉不健康的生活习惯。

教学重难点：

重点：辨别哪些是健康的生活方式，哪些是不健康的生活方式。

难点：引导学生选择健康的生活方式，改掉不健康的生活习惯。

教学对象：七年级学生 参加人数：48人

教具：PPT课件、班班通电脑等

教学步骤：

引入：大家听说过“生活方式”这个词吗？人的生活方式对健康有影响吗？有咋样的影响？这节课我们一起探讨“生活方式与健康”。（课件投影“生活方式与健康”。）

新课：1、阐明学习目标：讲述，（课件投影“学习目标”）

2、理解生活方式的概念：投影“一、什么是生活方式？…”并讲述。

3、设问“生活方式对健康有什么影响？”投影“二、生活方式对健康的影响”同学们都说有影响，那下面就请同学们分组讨论，（投影讨论题）“1.我们生活中有哪些是不健康的生活方式，对健康有什么影响？2怎样的生活方式才是健康的生活方式？”学生讨论交流。再任意请三个组在班级交流，教师点评，补充。

4、教师讲述：“同学们列出了许多不健康的生活方式，很好！不健康的生活方式还很多，世界卫生组织就精神卫生提出18种不健康的生活方式，请大家阅读了解。（投影课件：18种不健康的生活方式）。

5、讲述并投影“有人说:我一辈子吸烟，现在都九十岁了，很健康。说明吸烟对人没有危害。你能对此做出有力的反驳吗？”（学生发言，再投影文字和图片说明）。

6、再投影“有害健康的生活习惯”学生阅读，增强认识。

7、教师：“什么样的生活方式才是健康的生活方式呢？主要要做到以下六点”（投影并强调）

8、讲述并投影“选择健康的生活方式应从儿童和青少年开始…”所以（讲述并投影）“选择健康的生活方式应从我做起，从现在做起，从生活中的一点一滴做起，使自己茁壮成长，将来为中华民族多做贡献。”（投影“再见”）

教学小结：

本节课学生通过交流讨论、教师讲述、学生阅读等方式，学生充分认识到不良的生活方式对健康的危害，会自觉地选择健康的生活方式，改掉不健康的生活习惯。但本人水平有限，准备不充分，各部分衔接不够圆滑，敬请谅解。

使用建议：

要给学生足够的讨论时间。
