1、青岛版小学数学四年级上册角的认识教学反思“角的认识”教学反思“角的认识”教学反思在角的认识这节课中让学生在观察、操作、交流、反馈等活动中逐渐体会数学知识的产生、形成与发展的过程，获得积极的情感体验，感受数学的力量，同时掌握必要的基础知识与基本技能。它让学生以认知主体的身份亲自参加丰富生动的活动，完完全全地参与学习过程，真正成为课堂的主角，从而在体验和创造中学会数学。在教学中我做到了以下几点：一、联系实际，在本节课的教学中，我从感性的实物、图片入手，抽象出角的图形，再让学生在身边的事物中寻找角，做出角，最后自主探索比较角的大小的方法，引导学生逐步深化对角的认识，了解知识的来源，同时，教学中还应引

2、导组织学生自觉运用数学知识去分析解决生活中的实际问题，使学生深切体验到数学知识与生活实际的密切联系。感悟到数学就在我们身边，它源于生活，又用于生活。二、实践操作，为了帮助学生更好地认识角，整节课我将观察、操作、演示、实验、合作探究等方法有机地贯穿于各个教学环节中。在引导学生体验的基础上加以抽象概括，充分遵循 (从)感知(经)表象(到)一认知。通过找一找、看一看、做一做、比一比、说一说，画一画，学生活泼愉快地亲自参与、亲自体验到教师根据教学内容创造的不同教育情景中，在大量的实践活动中经历知识形成过程。三、回归生活，让学生体验知识应用过程要使学生在活动中和现实生活中学习数学，发展数学。在角的认识这

3、一课中，如寻找生活中的角，把空白留给了学生，让他们的思维有更大的空间，使不同的思维方式开展大比拼。这一过程中，不仅是学生的数感、空间观等的培养都通过体验得以实现；而且正确的思维方式在剧烈的碰撞中又得到了锤炼。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！16,nxg1bbiktd.wkj8iasf.e7kji,tkw3iiir1zet,pdbqvwgrhf2yl5kfmj2ghyexfh5c40jltj,fztxm1tywfqroayax47gydn5g,m94hkezv2.cqu6.o0bom3mgw8fs47juvqwjnc8xao
