在普通高中课程标准实验教科书·数学必修与选修的教学中,常常遇到一些内容或处理问题的思想方法学生说在初中没有学过或没有遇到过;同时也遇到初中已比较详细学习或了解过而高中还要再学习的内容,给教学带来了一点影响.现列举部分如下,并谈一点在教学中的处理方法或想法,供参考.1代数方面(1)初中降低了多项式计算、乘法公式和因式分解(十字相乘、分组分解不作要求).高中在一元二次不等式的解法中,由于初中上述内容教学要求的降低,所以不少学生对于解简
In ordinary high school curriculum standard experimental textbooks, compulsory math and elective teaching, often encounter some ideas or methods to deal with problems that students have not seen in junior high school or have not encountered; also encountered junior high school has been more detailed study or Understanding of the high school but also to learn the content, to teaching a little impact. Now cite some of the following, and talk a little teaching methods or ideas for reference.1 Algebra (1) junior high school to reduce the polynomial calculation , Multiplication formula and factorization (cross multiplication, packet decomposition is not required.) High school In the solution of one yuan quadratic inequality, due to the lower content of the junior high school teaching requirements, so many students for the solution
