仁爱英语七年级上册课件篇4
我说课的内容是北师大版数学七年级上册第三章的第一节课《字母能表示什么》,我主要从“教材分析”、“教法与学法分析”、“教学过程设计与说明”、“设计追求的特色”四个方面组织说课。
一、教材分析
(一)教材所处的地位
本节课北师大出版的新课程标准实验教材第三章的第一节课,在以前的学习中学生比较熟悉对具体数的操作,这是学生初次接触用较为抽象的字母来表示数,对字母表示数含义的理解有助于代数式以及方程的列出,是学习后续知识的关键。
(二)教学目标
1.知识目标:在现实情景中感受用字母表示数的意义,明确字母可以表示任何数,会用字母表示探索的规律,能用字母表示运算律和公式。
2.能力目标:经历探索数量关系,发现规律,运用字母表示规律,并通过运算验证规律的过程。
3.情感目标:一是体会字母表示数的意义,形成初步的符号感;二是进一步感受数学魅力,在学习过程中激发学生学习数学、探索数学奥妙的内在动力和外在的积极性,并在过程中培养学生的创新意识和实践能力。
(三)教学的重点、难点
1.立足本人的分析确定的:字母表示数的意义、数学规律的探索及符号表达,这些内容也是本课的难点。
2.可能基于学生个性差异、基础差异在学习过程中感觉困难的地方也是本课的难点。在教学过程中,我将认真注意,并尽力帮学生突破。
二、教法和学法分析
我校是定点的移民子女、进城务工子女就读学校,留守生在班级中占38%,学生的个性、基础能力差异很大,加上七年级学生处于小学与初中的衔接过渡初期,所以本节课我选择引导探索与分层教学相结合的方法。在新知的引出过程中,注意由浅入深,由特殊到一般地提出问题。引导学生自主探索,尤其在形成新知生长点的时候,充分发挥分层教学法的优点,帮学有余力的发挥潜能,挖掘
潜能,在先行的基础上发挥他们“先学后教”(后教就是帮助老师教,当老师的助手,在过程中达到教学相长的功效),教师抽出精力帮助学习困难的学生,帮助有“怪问题”的学生。注重时间分配,尽量做到先学在当堂,同层竞赛在当堂,异层帮辅在当堂,练习探讨在当堂、激发兴趣在当堂。
在教学过程中,关注每一学生,让每一个学生都动起来,促成学生成为学习的主人,从而发挥学生的主体作用。
三、教学过程设计及说明
(一)情景导入:利用电子白板的幕布创设问题情境(插入背景音乐,增加形象性和趣味性):“一只青蛙1张嘴,2只眼睛4条腿,1声扑通跳下水。两只青蛙2张嘴,4只眼睛8条腿,2声扑通跳下水。三只青蛙3张嘴,6只眼睛12条腿,3声扑通跳下水。6767”,让学生把这首儿歌继续唱下去,唱几句即可,然后老师提问:在这首儿歌中假如有a只青蛙,那么请同学们思考一下,应该有多少张嘴,多少眼睛多少腿,以及多少声普通跳下水?问题设计具有一定的趣味性,引出可以用字母表示数。目的是激发学生的学习欲望,体现数学来源于实际生活,数学是从人的需要中产生这一认识的基本观点。
在这个过程中,尽量发挥不同层次学生的作用,体现出学生的自主学习、自我探讨、总结交流等主体性的过程。
(二)实验操作:用电子白板拉出问题。鼓励学生用火柴棒或木棒,按照“口”、“日”、“目”搭建正方形,然后填表,找规律。按照同层独立先竞争、异层小组后合作、全班交流分享的办法进行。
填写下表:
1
在处理问题的过程中,充分抓住新知的生长点做文章,前四个空是铺垫,后一个空是新知生长点。对学有余力的学生,要求把100变成10000填空。这样做既培养了独立思考、勇于探索的能力,又培养了学生的帮扶意识和合作品质,还激发了学生的进取精神。
(三)问题解决和方法交流:按照小组交流和班级分享的办法进行。展示出想到的各种方法,小组推荐代表发言,鼓励学生对发言进行诊断评价,及时提醒学生注意发言、评价有无不妥,充分发挥教师平等中的首席作用。在这个过程中,还注意数学学习氛围的打造,保持教师刻意打造学习氛围的意识。
(四)随堂练习。分层次推出练习。设置三组,一是必做题2个;二是挑战题2个;三是攻坚题4个。设计时注重了层次,必做体现了保底;挑战和攻坚有层次的观注了个性差异。在同层之间进行竞赛性的统计,控制了学生思考的松紧度。
随堂练习的评价由先行的学生负责,教师给予适当的提醒。基本按照学生先做----代表评价-----教师适当帮助的步骤进行。
(五)课堂小结:主要通过学生回忆本节课所学内容,从内容、应用、数学思想方法、获取新知的途径方面先进行小结。教师尽量不补尾巴。以免形成学生总结时注意力不集中,教师总结才听的局面,在学生总结不全面可以给足时间让学生补充,真正当好平等中的首席。
(六)布置作业:内容略。
控制时间,尽量让学生当堂完成,不加重课后负担,不降低学习的积极性。
四、设计追求的特色
在本节课的设计过程中,我注重把握了以下几点:
1.既研究了教法,也研究了学法,基本按照以学定教的。思路进行设计。
2.重视了新知生长点,在新知生长点创造学生思考的问题,给足思考的空间。
3.注重了先学后教,而且尽可能让学有余力的学生去教,实现将带兵,兵促兵,兵教兵的局面。
4.发挥先进的教学手段如电子白板在教学中的辅助作用。
5.发挥学生的主体地位,摆正教师平等中的首席地位。
6.尽量做到课外不留作业,作业、练习分层安排,真正关注学生的个体差异。
7.注重创设学习氛围,激发兴趣,培养兴趣,巩固兴趣。
