《图形与位置》的教学反思

《图形与位置》的教学反思 本课的学习是在充分体验的基础上，学习用上下、左右、前后描述物体的性对位置，能在实际生活中正确辨认和运用。尊重生活经验，素材有童趣，强调学生主动参与活动，重视亲身体验。教材利用学生熟悉的游戏和身边常遇到的一些现象，启发学生借助已有经验学习有关方位的初步知识。 在一年级学生的生活经验里，已经积累了一些判断左右的方法和经验：吃饭时用右手拿筷子、写字时用右手握笔、况且大多数孩子在家庭、幼儿园已经了解了一些判断左右的方法，然而这种认识只是粗浅的、感性的，对不同的孩子来说层次也是不同的。基于以上分析，我在本课的设计中本着借助经验，重视体验，联系实际的原则进行设计，组织学生动手操作和主动观察的数学活动，吸引学生在亲身体验中学习知识。我设计了一连串的游戏活动，每个游戏活动既是一个新问题的提出，又为下面的游戏开展做好铺垫、准备，可谓环环相扣，层层递进，有水到渠成之感。学生们正是在一个个的游戏活动中深化了认知，锻炼了思维，增长了智慧。学生在游戏中学会了用前后左右上下来描述事物的相对位置。首先借助给大树找朋友的活动，唤起学生已有的生活经验开展学习，然后的游戏中重视体验，让学生亲身体验参与进来，在体验中学习知识。在活动中设计生活中实际的问题，让学生联系所学知识解决问题，并在应用中逐步巩固知识。同时在各个环

节中及时对学生进行评价，要有表扬性的语言，又有小红花，这样来激励学生的学习，更能提高学生的学习积极性。 然而，在课堂上我虽尽量按照新课标的要求去做，却也有许多不尽人意的地方。 首先，学生是学习的主人，教师是教学活动的组织者、引导者与合作者。学习过程是学生思维活动的过程，是学生在一定的条件下对客观事物的反映过程，是一个主动的建构过程。在课堂上我也努力去发挥学生的自主性，引导学生主动参与。但我始终有种牵着学生鼻子走的感觉，没有充分放手。 其次，对于时间的掌握上还需加强。例如在游戏二看谁的反应快的处理上稍显仓促，没有让学生更多的参与，尤其是对学生同桌互动上用时较少。 再次，对细节的处理上欠妥，数学是一门严谨的学习，老师的语言不可以有随意性，同样对每一个小环节的处理上也是不容一点马虎，要正确的处理知识。例如在本课的教学中，当我面对面教给同上下左右拍手活动时，同学们跟我做同样的动作而忽视了给学生解释镜面示范的道理。 一节课下来，感觉教学目标已基本完成，但是在一些细节性问题的处理上还欠妥当，有时学生说不来的情况下，自己很着急，险些替他们说出来，而对如何引导到正确的地方来做到很不够。今后，我将朝这个方向继续努力。

重点交流方法：先量出镇政府与各村庄之间的图上距离，再根据比例尺算出它们之间的实际距离。 3．提出问题（2）。 学生实际测量，并利用前面得到的距离及角度数据，描述各村庄的位置。 学生甲：刘庄在镇政府北偏东30°方向1350米处。 学生乙：郝庄在镇政府南偏西40°方向750米处。 ．．．．．． 4．提出问题（3）。 让学生在教材上标出汽车站的位置，然后交流。 三、用数对表示位置 1．出示教材第81页例2。 A（l，6）B（2，l）C（7，2）D（6，7）E（6，6） 2．提问：毎个字母中的数对表示什么意思？ 学生回答。 学生甲：Ａ的位置在第1列第6行。 学生乙：括号中的数字，第一个数表示第几列，第二个数表示第几行。 ．．．．．． 3．在教材中的坐标纸上描出A、B、C、D、Ｅ各点的位置。 在展示台上边展示边交流，重点说一说是怎样根据数对确定五个点的位置的。 四、巩固与练习 完成“练一练”第1、2、3题。 五、全课总结 今天我们复习了哪些知识？

图形与位置教学设计

图形与位置教学设计 《图形与位置》总复习教学设计 〔教材分析〕 《图形与位置》是人教版新课标实验教材六年级下册的教学内容，本课教学内容是基于学生在学习掌握了东、南、西、北，东南、东北、西南、西北八个方向，能运用数对、方向和距离等方法确定物体的位置、识别简单的路线图、以及比例尺的计算等知识的基础上进行的和回顾。通过系统的梳理，使学生进一步掌握确定位置的多种方法，培养学生的方向感与距离感，使他们能够辨认方向、确定位置，看懂和描述路线图。发展空间观念，提高解决实际问题的能力，为进一步的学习和发展奠定基础。 〔学情分析〕 学生已具有识别、确定物体位置的认识基础。但由于各知识点在安排上比较独立，各个教学段的目标和要求也不一样，学生的学习呈现一种断续、独立的状态。虽然各知识点看似简单，但学生遗忘快、掌握得不够扎实。不过，随着年龄的增长，他们的语言表达能力、动手操作能力和自主探索能力已有所提高。现在复习阶段的主要任务就 是要帮助学生理清各种表示物体位置的方法，沟通各知识之间的联系, 能综合运用所学知识灵活解决实际问题。

〔设计思路〕 本课以学生的发展为主线，让学生经历从生活到数学，又从数学到生活的过程，着眼于体验数学。利用课前预习忆一忆；梳理建构想一想、说一说、比一比；实践应用讲一讲、算一算、量一量、画一画扎扎实实地让学生在活动中建立空间观念，在情境中构建知识体系。 在复习部分，通过创设各种活动情境，为学生提供探究的空间和时间，鼓励学生自主探索、合作交流。力求让学生通过观察分析、独立思考、合作交流等方式，进一步全方位地复习确定物体的相对位置。 在应用知识解决问题部分，将图形与位置的问题放在了学生熟悉的现实生活中，让学生学会在现实情境中学会用不同的方式探索和思考问题，不断激发学生学习数学的积极情感，提高自己的思维水平，强化学生的空间观念，培养学生的数学应用意识。 〔复习目标〕 1、使学生能比较系统地运用各种描述的方法描述并确定物体的位置，体会用不同的方法确定位置，感受物体位置的关系是相对的；并能综合运用比例尺的知识确定物体之间的图上距离或实际距离。
