如何培养创新意识呢?一次观摩课,我看到了“等式的性质”同课异构的两种不同的展示,也看到学生的创新意识是可以在课上培养的.案例1中规中矩,平铺直叙,以知识为目的.第一位教师的教学过程如下:首先,老师根据本节课内容,创设了问题情境,给了几个问题,为研究等式的性质做好铺垫.问题1下列一元一次方程的解是多少?(1)2x=4(2)x+1=3(3)-1/3 x-5=4问题2下列式子的特征:(1)m+n=n+m(2)x+2x=3x(3)3×3+1=5×2(4)3x+1=5y
How to cultivate the sense of innovation? One observation class, I saw two different displays of “the nature of the equation ” heterogeneous with the same class, also saw the students’ sense of innovation can be cultivated in class. , Direct teaching, for the purpose of knowledge.The first teacher teaching process is as follows: First, the teacher according to the content of this lesson, created a problem situation, gave a few questions, to pave the way for the study of the nature of the equation.Question 1 The following (1) 2x = 4 (2) x + 1 = 3 (3) -1/3 x-5 = 4 Problem 2 Characteristics of the following equation: (1) m + n = n + m (2) x + 2x = 3x (3) 3x3 + 1 = 5x2 (4) 3x + 1 = 5y
