1高中数学新课程实施中的问题1.1新教材难易跨度较大在新课程的教材中,从课本的例题、练习、思考应用到拓展研究,台阶跨度较大。如必修5等差数列的学习,建议重视对学生从实际问题中抽象出数列模型能力的培养,通过必要的练习,掌握等差、等比数列中的基本数量关系,但要控制难度和复杂程度。而在书后的习题中出现了①已知奇偶项之比求公差。②已知等差数列的和求通项公式。③已知等 A new high school mathematics curriculum implementation problems 1.1 new textbooks more difficult span In the new curriculum textbooks, from textbook examples, exercises, thinking applied to the expansion of research, a larger span. Such as Compulsory 5 equal sequence, it is suggested that students should be trained to abstraction of the ability to train number models from their practical problems. By practicing the necessary exercises, it is necessary to master the basic quantitative relationships in the series of equal-difference and equality ratios. However, it is necessary to control the degree of difficulty and complexity . In the book after the exercise appeared ① Known odd or even than the ratio of tolerance. ② known arithmetic sequence and the sum of the formula. ③ known and so on
