一、问题的提出建构主义认为:数学学习应是一个以自主学习为前提,以合作交流为形式,以探究建构为目的的自我感悟过程。因此在新课改中,教师应尽可能为学生大胆对教材进行科学地重组,创设一个独立思考,自主探索的时空,让学生在学习中有所体验,有所感悟,有所发现。下面就是我在《可化为一元二次方程的分式方程》的教学中做的一点新的尝试,希望能给广大教师带来一点启示。二、课前准备通过解读教材我了解到:本课的“逻辑起点”是初一已学过的“一元一次方程”和“一元一次方程的
First, the issue put forward Constructivism believes that: Mathematics learning should be a self-learning as a prerequisite for cooperation and exchange as a form to explore the construction of self-perception process. Therefore, in the new curriculum reform, teachers should try their best to boldly reorganize the teaching materials scientifically, create an independent thinking space for self-exploration, let the students experience something in the study, some insights, some found. Here is a new attempt I made in the teaching of ”Fractional Equations that Can Be Converted to a Quadratic Equation“, hoping to bring a little inspiration to the teachers. Second, the preparation before class By reading the textbooks I learned that: ”logical starting point “ of this lesson is the first one has learned ”a dollar equation and “ and ”a one-time equation
