《圆柱与圆锥》是人教版《义务教育课程标准实验教科书数学六年级下册》第二单元第六课时的教学内容。根据课程标准对空间与图形教学的要求,本人按照“引出问题—联想猜测—实验探究—导出公式”的思路设计教学,在猜测的基础上进行实验和推理,注重了学生研究方法和思维方式的训练,提高了学生的自主能力。 “Cylinder and cone” is a humanistic version of “compulsory education curriculum standard textbook sixth grade mathematics” second unit sixth class teaching content. According to the requirements of curriculum standard for teaching of space and graphics, I designed the teaching according to the idea of ​​ “leads to the problem - the association speculation - the experimental inquiry - the derivation formula ”, carries on the experiment and the inference on the speculation basis, pays attention to the student research method and the thinking Way of training to improve the autonomy of students.
