1、人教版小学数学五年级上册梯形的面积评课角的初步认识评课梯形的面积评课梯形的面积一课，是在学生掌握了平行四边形和三角形面积计算的基础上进行教学的。学生已掌握了一定的学习方法，形成了一定的推理能力。为了充分利用原有的知识，探索、验证，从而获得新知，王丽老师给每个学生提供思考、表现、创造的机会,使他们成为知识的发现者、创造者，培养学生自我探究和实践能力。在这节课上,老师从学生的生活实际问题出发，一开始就让学生感受到生活中很多时候要计算梯形的面积，从而引发学生探究梯形面积的学习欲望。在这种内驱动力之下，学生调动自己已有的知识经验，探究出了很多种方法，培养了创新思维能力和自主学习的能力。这节课学生想出很

2、多方法推导梯形的面积公式，都是以探究平行四边形和三角形的面积为基础，学生的自主探究能力经过一定量的积累，经过长期这样的训练，学生探究所需要的时间越来越短，方法越来越多，创新能力越来越强。通过今天的听课，我对这节课进一步研究提炼，使我也认识到：在学生探究各种方法的时候，不必马上让学生统一到梯形的面积计算的规则公式中来，有套用模式之嫌。可以在最后让大家一起观察，把各种方法进行沟通、理解，再统一。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！16v8wmaw4qhhq3lhxodu8jh8jn0.,ky9j2o62gc0essmgvdrvsg
