传统习题课重在解决教科书、练习册余下的习题 ,新教材没有更多的习题供师生“题海战” ,正好给了师生创造的最佳契机 ,但如果不对新课程理念下的习题课作一番精心设计 ,也许又会变成变相的“题海术” .“问题是教学的心脏” ,数学教学始终离不开问题 ,而温故知新、重在发展的 The traditional exercise class focuses on solving the remaining exercises in textbooks and exercise books. The new textbook does not have more exercises for teachers and students to “combat the sea of ​​questions.” This is exactly the best opportunity for teachers and students to create, but if it is not an exercise class under the new curriculum concept After careful design, it may turn out to be a disguised “sea-magazine.” “Problems are the heart of teaching.” Maths teaching is always inseparable from the problem.
