一、突出从解决实际问题出发,让学生自主探索如在“平移与旋转”这一节的教学中,我向学生展示了大量学生所熟悉的图形,并让学生例举了生活中所熟悉的平移和旋转的现象,在此基础上,让学生就自己对平移和旋转的认识发表见解,从而得到平移和旋转的一些直观的基本特征。当学生对平移和旋转有了一些浅显的认识后,再利用教材上的做一做,让学生动手操 First, highlighting the solution to practical problems, allowing students to explore their own As in the “translation and rotation,” this section of teaching, I show students a lot of students are familiar with the graphics, and let students give examples of life Familiar translation and rotation phenomena, on the basis of which students are allowed to express their own knowledge of translation and rotation, derive some of the intuitive basic features of translation and rotation. When the students have some plain understanding of the translation and rotation, and then use the textbooks to do one to make students hands-on
