在教学中我力求做到以下几点一、体现“活动性”,让学生在活动中体验。《新课标》明确指出:“让学生在具体的数学活动中体验数学知识。”因此,我在新授部分以学生喜欢摸子活动开始,以期激发他们学习的热情和兴趣,使学生在活动过程中感知“一定”、“可能”、“不可能”,进而能判断生活与数学中的“一定”、“可能”、“不可能”这三种情况。并能用自己的语言描述事情发生的三种情况;(然而在课堂中,让学生把这三个词语放在一起例举数学与生活中的实例吧,学生说起来还是有一定难度的,所以在教学中我只有通过自己先举例在让学生说,这时学生才能说出例子来。)最后又让学生小组合作学习感知体验可能性是有大小的,达到巩固与应用的目的。
第一步骤是:游戏引入课一开始,我先出示2支铅笔,用手捏住一端,这样让学生产生一个错觉,再放开手,让学生重新进行判断,从而得出比较2个物体的长短要一端对齐的方法。从游戏引入,能很好地激发学生的好奇心,同时又利用学生的已有经验,由学生轻松得出比较长短的方法,为下面的活动做好了知识铺垫,既有趣,又有效。第二步骤是:比长短活动有了刚才比的方法的铺垫,再让学生找找自己想比长短的东西,然后进行自由比较。在这里,主要要放手让学生发挥自主性,但由于学生年龄太小,这里教师要加强引导,所以在让学生自己比之前,我让学生先说说想到了可以比什么。在学生自己动手的时候,我也深入其中,加强指导。在反馈时,还让学生演示一下,一方面要让学生体验到交流的成就感,另一方面也是培养其他学生认真倾听的习惯。
在交流的过程中,教师要站在“导”的位置上,放手让学生说,最后总结出,解决这个问题,重点要理解问题的实质含义:究竟是谁和谁比,谁是单位“1”。本环节的设计既拓宽了解题思路,又锻炼了表达能力,同时也提高了抽象概括能力。(五)巩固拓展:实战演练,我最棒!在练习的设计上,我兼顾了习题的层次性和开放性,使不同层次的学生都参与练习,以求训练思维、培养能力、形成技能。(六)课堂总结通过学生说一说本节课自己的收获,达到对本节课知识点的梳理与整理,进一步巩固对知识点的掌握。总之,本节课教学活动我力求充分体现以下特点:以学生为主体,充分关注学生的自主探究与合作交流。教师是学生学习的组织者、引导者、合作者,对一个问题的解决不是要教师将现成的方法传授给学生,而是引导学生寻找解决问题的策略,给学生一把在知识的海洋中行舟的桨,让学生在积极思考,大胆尝试,主动探索中,获取成功并体验成功的喜悦。
这是相隔两站的里程,相对问题1而言,难度有所增加。但数量关系不复杂,而此时学生已经有了问题1扎实的画图基础,所以我直接放手,让学生选择自己喜欢的方法画图,再算一算。3、会用图,能选择恰当的方法解决实际问题学习的最高境界是学以致用,画一画的目的是帮助自己解决问题,所以在学生初步掌握借助画图理解问题的基础上,我及时向学生提问,你还想求哪段,鼓励学生小组交流,并发现总结起点相同的里程问题的解决策略。在问题3时,我还是放手自主探究,因为有了前面的基础,此时,聪明的学生已经掌握了求两站之间的里程的方法,而接受能力稍微慢一点的学生通过画一画明确算式中相减的两个数量分别表示的哪一段路程,也能解答出来,这时再乘胜追击,鼓励学生说一个算式,让其他学生求的是哪两站之间的里程,这样的设计既巩固学习方法,又进行了开拓延展,可谓一举两得。本节课学生经历、感受着,借助画图分析问题、理解问题、解决问题的优越性。让学生在尝试、探索中发展了思维,提高了能力。
一、说教材1、教学内容北师大版小学数学五年级上册第五单元的第一课时《分数的再认识(一)》。2、教材分析本课是学生在三年级初步认识分数的基础上,进行深入和拓展的。在三年级,学生已结合情境和直观操作,体验了分数产生的过程,认识了整体“1”,初步了解了分数的意义,能认、读、写一些简单的分数。本节课是在此基础上,进一步引导学生认识和理解分数,为后面进一步学习、运用分数知识做好铺垫。本课的课题是《分数的再认识》,这个“再认识”,我想应该有两方面的含义,一是进一步认识、理解分数的意义,二是结合具体的情境,让学生体会“整体”与“部分”的关系,体会“整体不同,同一个分数所对应的数量也不同”,从而体验数学知识形成的全过程。3、教学目标根据教学内容和学生的认知能力,我将本节课的教学目标制定如下:
二、教法根据教材呈现的内容,我在开展教学活动时是从以下几个方面思考。1、出示情境图,鼓励学生分析情境中的数学信息和数量关系,明确所要解决的问题,然后了解要解决这个问题需要什么样的条件,进而列出算式。2、讨论具体的计算方法。教材中呈现了两种计算方法。在这个过程中,教师可以先让学生自主进行计算,再组织讨论和交流算法之间的联系,明白分数混合运算的顺序。3、对问题的解决加以解释,即航模小组有3人。三、学法通过本节教学,学生学会运用直观的教学手段理解掌握新知识,学会有顺序的观察题、认真审题、正确计算、概括总结、检查的学习习惯。四、教学程序(一)谈话设计意图:激发学生兴趣,调动学生学习的积极性。(二)复习旧知1、复习整数混合运算的顺序。
在答案的汇总过程中,要肯定学生的探索,爱护学生的学习兴趣和探索欲.让学生作课堂的主人,陈述自己的结果.对学生的不完整或不准确回答,教师适当延迟评价;要鼓励学生创造性思维,教师要及时抓住学生智慧的火花的闪现,这一瞬间的心理激励,是培养学生创造力、充分挖掘潜能的有效途径.预先设想学生思路,可能从以下方面分类归纳,探索规律:① 从加数的不同符号情况(可遇见情况:正数+正数;负数+负数;正数+负数;数+0)② 从加数的不同数值情况(加数为整数;加数为小数)③ 从有理数加法法则的分类(同号两数相加;异号两数相加;同0相加)④ 从向量的迭加性方面(加数的绝对值相加;加数的绝对值相减)⑤ 从和的符号确定方面(同号两数相加符号的确定;异号两数相加符号的确定)教学中要避免课堂热热闹闹,却陷入数学教学的浅薄与贫乏.
5、请小朋友回去后把学会的儿歌念给爸爸妈妈听,请他们猜猜,儿歌里藏着多少数字?小鸡一家一共有几只小鸡?活动总结及反思1、儿歌的内容和形式比较吸引幼儿。整个活动的设计由易到难,层层递进,提问体现层次性。幼儿通过看、听、表演等形式,表现出对学习数字歌谣的浓厚兴趣。儿歌的主题贴近幼儿的生活,有利于幼儿理解、分享交流、想象扩散。在目标、内容上能与计算、德育、生活相结合,体现整合观。2、儿歌中小鸡一家还隐藏着数字"10",可以让幼儿回家和家长一起把数字"10"编入儿歌。这样使儿歌更有完整性,也能让家长参与,体现家园互动。3、幼儿在念儿歌时,有些生疏,教师可以提醒幼儿想着数字顺序、记着数字念儿歌。让孩子学会念数字歌谣的方法4、活动的过程中幼儿可能容易走神,如何抓住幼儿的注意力,让整堂课可以顺利的完成成为考验教师的难点。
◇探究提示:传统文化对现实生活是财富还是包袱,要具体问题具体分析,不可一概而论。例如,“忠”是我国古代伦理道德的最高原则,《左传》中的“临患不忘国,忠也”,要人们尽自己最大努力,为维护国家利益而献身,是积极的,对现实生活来说就是财富,应该提倡;而宋代的“君要臣死,臣不得不死”的封建忠君思想对现实生活来说是包袱,应该抛弃。2.继承传统文化的正确态度如何继承传统文化,发挥传统文化的积极作用呢?正确的态度是:“取其精华,去其糟粕”,批判继承,古为今用。面对传统文化,要辩证地认识它们在现实生活屯的作用,分辨其中的精华和糟粕。对于传统文化中符合社会发展要求的、积极向上的内容,应该继续保持和发扬。对于传统文化中不符合社会发展要求的、落后的、腐朽的东西,必须“移风易俗”,自觉地加以改造或剔除。
思考:在我们今天的生活中,应该如何认识“孝”道?(“孝”为中华民族传统道德之本。在封建社会,“孝”被异化为封建统治阶级统治人民、维系政权的一个最重要的工具;一切听命于“一家之长”的观念,使人们往往屈从于独断的权威或传统的家庭礼教,失去了独立的人格。另一方面,“孝”从它本身意义出发,所包含的尊老、敬老、养老,以及亲亲、爱人、爱国,正是中华民族的一大传统美德,是中华民族家庭和睦、邻里相亲、社会稳定的重要内在因素。因此,孝道已被列为中华传统道德教育的重要内容。)所以我们要辩证地认识传统文化在现实生活中的作用,做到“取其精华,去其糟粕;批判继承,古为今用”。对于传统文化中符合社会发展要求的、积极的、向上的内容,应该继续保持和发扬。对于传统文化中不符合社会发展要求的、落后的、腐朽的东西,必须“移风易俗”,自觉地加以改造或剔除。2、正确对待传统文化的意义
一、知识与能力:(1)了解中国古代不同时期的文学特色;(2)了解、诗,词、歌、赋等各种不同的知识内容和形式,知道和掌握一定数量的名家作品;(3)拓宽文化视野,提高赏析和运用古代文学作品的能力。二、过程与方法:(1)通过教科书及教师提供的材料以及自己的日常积累,通过阅读,讨论,分析,评论了解各个不同时期的文学发展特色。(2)通过阅读,观察,练习,欣赏,表演,评论,创作等方式积极参与教学;通过独立思考或合作学习对所学的内容进行比较,概括和阐释;学会合作学习和相互交流。三、情感态度与价值观:通过本课学习,了解中国古代灿烂的文化。通过对文学家、诗人及其文学作品的分析,把学生带进文学艺术的殿堂,感受古人的呼吸,思想,情操。增强文化修养。
苏联文学的沿革,既反映了苏联社会的伟大思想性变革,又反映了苏联文坛活跃与混乱并存的局面,特别是其所具有强烈的意识形态色彩是苏联社会深层次变化的风向标。(2)20世纪的亚、非、拉美文学20世纪亚、非、拉美文学的繁荣伴随着民族民主运动的高涨,其主流都体现了反对殖民压迫、反对社会不公的爱国主义精神。出现了许多颇有影响的作家和作品。泰戈尔是印度近现代文学的光辉代表,为印度现代民族主义奠定了基础。其代表作《戈拉》塑造了爱国的印度民族主义知识分子形象。泰戈尔是首位获诺贝尔文学奖的东方作家。鲁迅是中国文学革命的巨匠,他的《呐喊》集,昭示着中国新文学时代的到来。哥伦比亚作家马尔克斯的《百年孤独》,描绘加勒比海沿岸小城百年孤独的原因及打破这种状态的途径。
