教材: 子集目的: 让学生初步了解子集的概念及其表示法,同时了解等集与真子集的有关概念.过程: 一 提出问题:现在开始研究集合与集合之间的关系.存在着两种关系:“包含”与“相等”两种关系. 二 “包含”关系—子集1. 实例: a={1,2,3} b={1,2,3,4,5} 引导观察. 结论: 对于两个集合a和b,如果集合a的任何一个元素都是集合b的元素,则说:集合a包含于集合b,或集合b包含集合a,记作aíb (或bêa)也说: 集合a是集合b的子集.2. 反之: 集合a不包含于集合b,或集合b不包含集合a,记作aëb (或bëa) 注意: í也可写成ì;ê也可写成é;í 也可写成ì;ê也可写成é。3. 规定: 空集是任何集合的子集 . φía 三 “相等”关系1. 实例:设 a={x|x2-1=0} b={-1,1} “元素相同”结论:对于两个集合a与b,如果集合a的任何一个元素都是集合b的元素,同时,集合b的任何一个元素都是集合a的元素,我们就说集合a等于集合b, 即: a=b2. ① 任何一个集合是它本身的子集。 aíaì¹② 真子集:如果aíb ,且a¹ b那就说集合a是集合b的真子集,记作a b③ 空集是任何非空集合的真子集。④ 如果 aíb, bíc ,那么 aíc 证明:设x是a的任一元素,则 xîa aíb, xîb 又 bíc xîc 从而 aíc 同样;如果 aíb, bíc ,那么 aíc⑤ 如果aíb 同时 bía 那么a=b 四 例题: p8 例一,例二 (略) 练习 p9 补充例题 《课课练》 课时2 p3五 小结:子集、真子集的概念,等集的概念及其符号 几个性质: aíaaíb, bíc þaícaíb bíaþ a=b 作业:p10 习题1.2 1,2,3 《课课练》课时中选择

七彩蝴蝶 第三教时
一、 教学目标:
1、通过美术欣赏和美术表现,使学生感受美的存在。
2、提高学生对美的感受力和艺术表现能力,并能在审美活动中充分拓展他们的思维和想象力。
二、教学重点、难点:
1、通过感知蝴蝶的形态和多姿的花纹及色彩,练习对颜色的综合运用。
2、理解对称的形态,找出规律,展开不同的评价方式。
三、教学准备:
课件、彩纸、剪刀等
四、教学过程:
(一)、猜一猜:
课件:表现蝴蝶的生长变化的过程:(每出示一个过程就猜一猜)毛毛虫的蠕动—结茧—蜕变化蝶---飞舞在花丛中的蝴蝶。
(二)、看一看:
出示不同形态、花纹、色彩的蝴蝶图片或标本视频展示,学生讨论,对蝴蝶的特征进行分析,归纳蝴蝶的基本形态,蝴蝶的共同特征是什么? ----对称。并举出例子。
(三)、听一听:
倾听乐曲:《扑蝶》引导学生感受乐曲,表达自己的感受,为乐曲命名。
(四)、读一读:
“蝴蝶飞,我不追,蝴蝶落,我不要。”这是农村学生看见蝴蝶时哼唱的童谣。或者朗读“小蝴蝶,穿花衣,猫抓你,飞到西,飞到我的手心里,鸡吃你,说说话,飞到东,放了你。
(五)、赏一赏:
课件:你知道很多艺术家都喜欢以蝴蝶为题材进行创作,你能说出几钟吗?(剪纸、舞蹈、工艺品、手饰等)课件欣赏。
(六)、演一演:
欣赏一段蝴蝶飞舞的录象:蝴蝶飞舞时的动态是怎,怎样的?谁来模仿一下。
(七)、做一做:
我们可以采用什么样的表现手法来表现蝴蝶呢?
老师示范剪纸:1、将彩纸对折
2、用铅笔画出蝴蝶的半边轮廓
3、用剪刀剪下轮廓。
4、将蝴蝶贴在作业本上,再添画。
学生用剪纸的方式完成一只蝴蝶。学生制作,教师巡回指导。
五、课堂总结、下课。
教学反思:
有人说,孩子的模仿能力非常强。教师一示范,学生自然就会跟着模仿。所以有人提议,为了培养学生的创新思维、创造力。教师在课堂上最好不示范,鼓励学生大胆创新,就算要示范,也要一示范完就把范作收起来,避免学生临摹。教师示范,学生就会跟着模仿,这种情况确实存在。虽说模仿也是一种学习,但是一味的模仿,就会阻碍创新思维、创造能力的发展。还有人说,教师的示范、演示是对学生能力、智力的不信任。所以示不示范是一直困惑着我的一个大问题。在平时的课堂上,我一般的做法是绘画内容不示范,大的原则是以引导学生回忆、想象为主,偶而示范一下难点而已;手工制作就完整示范整个制作过程。我也不知这样处理是否妥当。但在实际的课堂教学中,我觉得应关注学生的实际情况,因材施教,具体问题具体分析。在今天《七彩蝴蝶》这一课中,我在二(1)班授课时重点示范了剪蝴蝶,并且让学生完整看完我的操作过程,结果留给学生制作时间太少,在课堂上学生无法完成今天的作业。下午在二班我就尝试不示范,让学生自主创作。也有学生自己开始动手制作起来的,也有画的。但是还有很多学生不会制作而又不满足于绘画,他们对于手工制作有更大的兴趣。这时不会制作的学生会很困惑、很苦恼,他们一般会手举工具材料围到讲台前,很焦急地央求示范一下:“老师,怎么做的,这是怎么做的呢?”“帮我做一下啊!”“老师,做一下给我们看吧!”而且学生的人数还不少,有些是真不懂,有些是来凑热闹的,更有一些本来已会做的,看到老师在示范,他们也要来看个究竟,生怕有更好的方法没学到。针对这个问题,在课后我又想到了另外一个方法,那就是我在教学生剪蝴蝶花纹时所采用的:鼓励会做的学生充当“小老师”,帮带不会做的学生。一开始教师就不示范,让生生之间互动起来,自主探讨方法方式,自由选择帮带对象。当然以上的方法可不可行,就有待于接下来的实验吧!希望我在以后的教学实验中探索出更多更适合学生发展的好方法。
