    北师大版初中八年级数学上册从统计图估计数据的代表说课稿

    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

    北师大版初中八年级数学上册认识二元一次方程组说课稿2篇

    我们遇到的往往就是这样的方程组,我们要想比较简捷地把它解出来,就需要转化为同一个未知数系数相同或相反的情形,从而用加减消元法,达到消元的目的.请大家把解答过程写出来.解:①×3,得:6936xy??,③②×2,得:3486??yx,④③-④,得:2?y.将2?y代入①,得:3?x.根据上面几个方程组的解法,请同学们思考下面两个问题:(1)加减消元法解二元一次方程组的基本思路是什么?(2)用加减消元法解二元一次方程组的主要步骤有哪些?(由学生分组讨论、总结并请学生代表发言)[师生共析](1)用加减消元法解二元一次方程组的基本思路仍然是“消元”.(2)用加减法解二元一次方程组的一般步骤是:①变形----找出两个方程中同一个未知数系数的绝对值的最小公倍数,然分别在两个方程的两边乘以适当的数,使所找的未知数的系数相等或互为相反数.②加减消元,得到一个一元一次方程.③解一元一次方程.

    北师大版初中八年级数学上册一次函数的图象说课稿

    [互动2]师:请大家从上面的解题经历中,总结一下如果已知函数的图象,怎样求函数的表达式?小组讨论之后再发表意见。生:第一步根据图象,确定这个函数是正比例函数或是一次函数;第二步设函数表达式;第三步:根据表达式列等式,若是正比例函数,只要找图象上一个点的坐标就可以了;若是一次函数,则需要找到图象上两个点的坐标,然后把点的坐标分别代入所设的解析式中,组成关于R、b的一个或两个方程。第四步:求出R、b的值第五步:把R、b的值代回到表达式中就可以了。师:分析得太好了。那么,大家说一说,确定正比例函数的表达式需要几个条件?确定一次函数的表达式呢?要说明理由。生:确定正比例函数需要一个条件,而确定一次函数需要两个条件。原因是正比例函数的表达式:y=Rx(R≠0)中,只有一个系数R,而一次函数的表达式y=Rx+b(R≠0)中,有两个系数(待定)R和b。

    ③如果某人本月缴所得税19.2元,那么此人本月工资薪金是多少元?根据所给条件写出简单的一次函数表达式是本节课的重点加难点,所以在解决这一问题时及时引导学生总结学习体会,教给学生掌握“从特殊到一般”的认识规律中发现问题的方法。类比出一次函数关系式的一般式的求法,以此突破教学难点。在学习过程中,我巡视并予以个别指导,关注学生的个体发展。经学生分析:(1)当月收入大于1600元而小于2100元时,y=0.05×(x-1600);(2)当x=1760时,y=0.05×(1760-1600)=8(元);(3)设此人本月工资、薪金是x元,则19.2=0.05×(x-1600) X=1984五.教学效果课前:通过本节课的学习,教学目标应该可以基本达成,学生能够理解一次函数和正比例函数的概念,以及它们之间的关系,并能正确识别一次函数解析式,能根据所给条件写出简单的一次函数表达式,且通过本节课的学习学生的抽象思维能力,数学应用能力都能有所提升,
