1、青岛版小学数学五年级上册三角形的面积听评课记录-微课拍摄脚本（编辑）设计模版三角形的面积听评课记录 在本次教研活动我有幸执教三角形的面积一课，在教学后，我感觉这节课教学目标达成度较好，重难点处理恰到好处，但微课程的利用效率不高，有些与课堂内容重复，有待改进。下面是各听课老师的点评。 杨洁老师：合作探究有层次、有深度。在推导三角形的面积公式时，给予学生充分动手操作的机会。让学生在动手操作的过程中感受、感悟两个完全一样的三角形可以拼成一个平行四边形。韩老师安排了两个活动，让学生充分动手操作。第一个“拼一拼”，让孩子们动手摆，尝试着把三角形转化成我们学过的图形。当孩子们有了一定的基础后，又进行了第二

2、个活动“比一比”，更深层次的让学生通过比面积、比底和高，然后推导出三角形的面积公式。整个活动中，台下交流的井然有序，台上展示的淋漓尽致，学生表现出了充分的自信心。这一环节适时的小组合作,给学生提供了充分的自主学习的活动空间和广泛交流的机会,不仅突出了重点、突破了难点，还真正体现了学生学习的主体性和小组合作的有效度。 李倩老师：练习的设计具有很强的目的性和多样性。整节课安排了，基础型练习、提高性练习、操作探究性练习。多样化的练习既巩固了新学的知识，又训练了孩子们思维的灵活性。薛静老师：教学过程渗透了数学文化。在学生合作推出了三角形的面积公式后，韩老师利用微课程展示了用一个三角形推出面积公式的方法

3、。练习环节，由易到难，层层递进。对于新知掌握起到了很好的巩固，并做了有效提升。这样的练习设计，对于学生数学思维的发展起到了很好的促进作用。这节课中韩老师对知识点的把握很到位，我个人觉得还有一点点需要改进的地方，比如在学生的探究过程中，老师放手了，但是放手的力度还不够。还有课堂上与学生思维的准确对接、学生的姿态纠正、课堂语言的语速等等。结束语！祝大家学到有用的知识，提升自己的能力，实现自己的梦想，踏踏实实干好每一件事，为美好的明天而努力！16f5ulh0cqczl,kbcz,8j4yq0mr,buq7pelzheb02675rb50umwcu9yatr9xe8ernaxfol4m.bg0tidb
