使学員获得布列和解答一次方程的技能和熟练技巧,是初中代数教学中的中心問題之一。同时布列一元一次方程也是学員学习初中代数的一大难点。因此,如何进行布列一元一次方程的教学是初中代数教学的一項重要问题。一、学員学习布列一元一次方程中的困难 1.用算术解应用题的思维过程布列方程。学員在初学代数时,对用代数解应用題的特点,及用代数解应用題和用算术解应用題有何异同,不能一下领会,在布列方程时往往仍按算术解应用題的思維过程分析题目,仅在形式上把算式写成等式即算式=x(已知数組成的式子=x)。如在解答問题“甲乙两人同时从相距60里的两地相对而行,甲每时走12里,乙每时走
It is one of the central issues in the teaching of algebra in junior high school that students are given the skills and proficiency skills required to formulate and solve an equation. At the same time, it is also a major difficulty for students to learn junior high school algebra. Therefore, how to carry out the teaching of one-dimensional equations is an important issue in junior high school algebra teaching. First, the students learn the difficulties in the formation of a one-dimensional equation 1. The mathematical equations are used to solve equations of thought. Students in the algebra of algebra, the characteristics of the use of algebraic solution to the problem, and the use of algebra to solve the problem and the use of arithmetic to solve the problem of similarities and differences, can not understand it, in the form of mathematical equations often still apply the thinking of the problem The process analysis subject only formulates equations as equations = x (formulas of known numbers = x). For example, when answering the question, "A and B are both facing each other from the two places 60 miles apart, A goes 12 miles each, and B walks each time.
