当今的教材改革已经把许多教学内容做了下移,如大学的极限、导数、简单的古典概率和统计特征等内容已编入到新一轮的高中数学教材当中,原中学里的统计常识、方程、负数、式的分解、有序数对、排列组合、运筹、集合等数学知识和数学思想已在小学数学教材中占了不小的篇幅.一、适当提高,开放练习在新课教学时就适当拓展教学的空间,适当提高对新授知识的难度,让学生的学习具有一定的挑战性和创造性.设计拓展练习应该考虑到全体学生,结合教材的内容,设计一
Today’s textbook reform has made a lot of teaching content down, such as the university’s limit, derivative, simple classical probability and statistical features have been incorporated into a new round of high school mathematics textbooks, the original secondary school statistical common sense, Mathematical knowledge and mathematical thought of equations, negative numbers, type decompositions, ordinal pairs, permutations and combinations, operations and collections have taken up a considerable amount of space in primary school mathematics textbooks. Properly expand the teaching space, the appropriate increase of the difficulty of new knowledge, so that students have a certain degree of challenge and creativity. Design and development exercises should take into account all the students, combined with the content of teaching materials, design a
