一、分层教学的实施1.根据教学大纲,制定分层教学目标,实施备课分层《一元二次方程》这一章的教学,要求A层面学生能判断一元二次方程,知道根的概念,会把方程化为一般形式,掌握一元二次方程的解法的操作步骤.B层面学生,则要求他们从理解公式推导的过程中深刻理解公式,能领会知识点之间的联系,灵活运用各种方法解方程.应要求C层面学生会推导公式,可以在具体的复杂题型中灵活运用,并掌握在此过程中所用到
First, the implementation of a layered teaching 1. According to the syllabus, the development of hierarchical teaching objectives, the implementation of lesson preparation layered “one yuan quadratic equation” chapter of the teaching, requires A level students can determine a quadratic equation, to know the concept of the root , will turn the equation into a general form, grasp the operation steps of the solution of the one-dimensional quadratic equation. The B-level students require that they deeply understand the formula from the process of understanding the formula derivation, can understand the connection between the knowledge points, and use each A method for solving equations. The C-level student council shall be required to derive formulas that can be flexibly used in specific complex questions and used in this process.
