(一)说教材 《虞美人》选自高中语文统编版必修上册·古诗词诵读。《虞美人》是词中的代表作品,是李煜生命中最为重要的一首词作,极具艺术魅力,对于陶冶学生的情操,丰富和积淀学生的人文素养意义非凡。(二)说学情总体来说,所教班级的学生基础不强,学习意识略有偏差,在学习过程中需要教师深入浅出,不断创造动口、动手、动脑的机会,他们才能更好地达成教学目标。(三)说教学目标根据教学内容和学情分析,确定如下教学目标(1)探究这首词的内涵,了解李煜及其创作风格。(2)通过对本词的品析,提高词的鉴赏能力。(3)通过对比阅读,体会李煜词 “赤子之心” 、“以血书者”的特色,体味其深沉的亡国之恨和故国之思。
目的:进一步理解追击问题的实质,与课程引入中的灰太狼追喜羊羊故事呼应,问题得到解决。环节三、运用巩固活动内容:育红学校七年级学生步行郊外旅行,1班的学生组成前队,步行速度为4千米/小时,3班的学生组成后队,步行速度为6千米/小时,1班出发一个小时后,3班才出发。请根据以上的事实提出问题并尝试回答。问题1:3班追上1班用了多长时间 ?问题2:3班追上1班时,他们离学校多远?问题3:………………目的:给学生提供进一步巩固建立方程模型的基本过程和方法的熟悉机会,让学生活学活用,真正让学生学会借线段图分析行程问题的方法,得出其中的等量关系,从而正确地建立方程求解问题,同时还需注意检验方程解的合理性.实际活动效果:由于题目较简单,所以学生分析解答时很有信心,且正确率也比较高,同时也进一步体会到了借助“线段图”分析行程问题的优越性.
一.学生情况分析对于三角形的内角和定理,学生在小学阶段已通过量、折、拼的方法进行了合情推理并得出了相关的推论。在小学认识三角形,通过观察、操作,得到了三角形内角和是180°。但在学生升入初中阶段学习过推理证明后,必须明确推理要有依据,定理必须通过逻辑证明。现在的学生喜欢动手实验,操作能力较强,但对知识的归纳、概括能力以及知识的迁移能力不强。部分优秀学生已具备良好的学习习惯,有一定分析、归纳能力。
2、课标要求对于本节课内容课标要求:探索并掌握两个三角形全等的条件;注重所学内容与现实生活的联系,注重经历观察、操作、推理、想像等探索过程。初步建立空间观念,发展几何直觉;在探索并掌握两个三角形全等的条件,与他人合作交流的过程中,发展合情推理,进一步学习有条理的思考与表达。二、学生分析 1、七年级学生的理解能力和思维特征和生理特征,学生好动性,注意力易分散,爱发表见解,希望得到老师的表扬等特点,所以在教学中应抓住学生这一生理心理特点,一方面要运用直观生动的形象,激发学生的兴趣,使他们的注意力始终集中在课堂上;另一方面要不断创造条件和机会,让学生发表见解,充分发挥学生学习的主动性,体现学生的主体地位。
1.小明调查了班级里20位同学本学期计划购买课外书的花费情况,并将结果绘制成了下面的统计图.(1)在这20位同学中,本学期计划购买课外书的花费的众数是多少?(2)计算这20位同学计划购买课外书的平均花费是多少?你是怎么计算的?反思?交流*(3)在上面的问题,如果不知道调查的总人数,你还能求平均数吗?2.某题(满分为5分)的得分情况如右图,计算此题得分的众数、中位数和平均数。活动4:自主反馈1.下图反映了初三(1)班、(2)班的体育成绩。(1)不用计算,根据条形统计图,你能判断哪个班学生的体育成绩好一些吗?(2)你能从图中观察出各班学生体育成绩等级的“众数”吗?(3)如果依次将不及格、及格、中、良好、优秀记为55、65、75、85、95分,分别估算一下,两个班学生体育成绩的平均值大致是多少?算一算,看看你估计的结果怎么样?*(4)初三(1)班学生体育成绩的平均数、中位数和众数有什么关系?你能说说其中的理由吗?
探究活动二的安排,是要让学生明确只靠实验得出的结论,可能会以点带面,从而进一步说明学习推理的必要性。并小结出:如果要判断一个结论不正确只要举一个反例就可以了。探究活动三的安排是说明只靠实验得出的结论也不可靠,必须经过有根有据的推理才行。活动交流:(1)在数学学习中,你用到过推理吗?(2)在日常生活中,你用到过推理吗?这是一座桥梁,把课堂引向推理的方法。例题的安排,可以让学生学会简单的推理方法,同时增强学生的学习兴趣。课堂练习:①游戏:苹果在哪里?②判断:是谁打破玻璃?把练习变成游戏的形式,也是为了增加课堂的趣味性,提高学生的学习兴趣。课堂小结:进一步明确学习推理的必要性。课后作业:①课本习题6.1:2,3。②预习下一节:定义与命题
Ⅵ.活动与探究某种“15选5”的彩票的获奖号码是从1~15这15个数字小选择5个数字(可以重复),若彩民所选择的5个数字恰与获奖号码相同,即可获得特等奖.小明观察了最近100期获奖号码,发现其中竟有51期有重号(同一期获奖号码有2个或2个以上的数字相同),66期有连号(同一期获奖号码中有2个或2个以上的数字相邻).他认为获奖号码不应该有这么多重号和连号,获奖号码可能不是随机产生的,有失公允.小明的观点有道理吗?重号的概率大约是多少?利用计算器模拟实验可以估计重号的概率.[过程]两人组成一个小组,利用计算器产生1~15之间的随机数.并记录下来,每产生5个随机数为一次实验,每组做10次实验,看看有几次重号和连号.将全班的数据汇总集中起来,就可估计出1~15之间的整数中随机抽出5个数出现重号和连号的概率.
(四)提高应用已知:在△ABC中,已知∠ACB=90°,CD⊥AB于D,请找出图中的相似三角形,并说明理由。设计意图:训练学生灵活运用知识的能力(五)小结反思1.、相似三角形的判定方法一:如果一个三角形的两个角分别与另一个三角形的两个角对应相等,那么这两个三角形相似. 2、在找对应角相等时要十分重视隐含条件,如公共角、对顶角、直角等. 3、掌握由平行线构造的两类相似图形:一类是A字型,另一类是X型. (回顾定理,强调两个基本图形,培养学生养成认真观察,注意寻找图形中的隐含信息的意识) 4、 常用的找对应角的方法:①已知角相等;②已知角度计算得出相等的对应角;③公共角;④对顶角;⑤同角的余(补)角相等.
准备200张卡片,在上面分别写上1,2,3,…,200,将卡片装入布袋里.第一次从布袋中盲目地取出一张,把号码记下,这个号码就算是消息的发布者,暂时不放回。第二次,从布袋中盲目取出三张,记下号码,这算是第一批听到消息的三个人,留一张暂时不放回(这张卡片代表下一次传播消息的人),另两张放回。把第一张卡片放回,然后第三次从布袋中盲目取三张卡片,记下号码.这算是第二批听到消息的三个人.留一张暂时不放回,其余两张放回.把第二次摸出的并暂时留下的一张卡片收回,然后第四次从布袋中摸……看一下,15次后,有没有被重复摸出的?上述消息传播问题是很有实用价值的,比如,在医疗事业中,必须十分注意疾病的重复感染问题,因为传染病的传播就像消息传播一样,既然重复听到消息的可能性是很大的,当然重复感染的可能性也是很大的。
本环节运用了一个阶梯式的问答方法,帮助突破本节课的难点。同时,从具体的实际问题入手,由特殊问题到一般规律的揭示,不仅解决了难点问题,而且从另外一个角度讲也渗透给了学生的数形结合思想,还有利于学生主动探索意识的培养。4、自主评价本环节主要是应用本节课所学的知识以及所积累形成的学习经验和体验解决问题的过程,即课堂巩固训练。在练习题的选择上,由简单到复杂。先是结合图象获取信息进行简单的填空和选择,此题属于A组题型,检验学生的掌握情况;然后进行了一道B组题,关于“一次函数与一元一次方程的关系”知识点的灵活运用,进一步通过练习体会它们的关系。5、自主发展:最后一道则是特殊的区别于之前所学习的分段函数练习,发散学生思维问题的训练。让学生体会分段函数的特点,并掌握求分段函数解析式的方法。
接下来请同学们改造这五个句子,变成“如果??,那么??”句式,其实就是一个语文环节中的造句,同学们很活跃,纷纷举手发言。课堂检测练习我用到的是课本221页习题6.2第1、2题,有个别同学会做错,做错点在于对判断还把握不够到位,还有少数同学对定义与命题的理解产生混乱。据此,我提出:定义与命题两个概念该如何区别?同学们举手发言:定义是一个描述性的概念,而命题是判断一件事情的句子。还有同学说道:定义就是一个“??叫??”的句式,命题就是“如果??那么??”的句式。在教学中,学生对定义与命题的把握还是比较清楚的。大部分学生可以口头完成导学案设计的题目。能够迅速的把一个命题转化成“如果?那么?”的形式.利用疑问句和祈使句的特点,判定不是命题的语句.迅速的掌握情况还是比较可以的。
