导入法是引起学生注意,激发学习兴趣,引起学生动机,明确学习目的和建立知识间联系的教学活动方式。它能将学生的注意力吸引到特定的教学任务和程序之中,所以又称为定向导入。由于数学高度抽象性和严密逻辑性这一特点决定了学生在学习数学时极易产生枯燥乏味的感觉,从而削弱乃至 The introduction method is an instructional activity that attracts the attention of students, stimulates interest in learning, leads to student motivation, defines the purpose of learning, and establishes links between knowledge. It can attract students’ attention to specific teaching tasks and procedures, so it is also called directed import. Because mathematics is highly abstract and tightly logical, students are apt to have a dull feeling in learning mathematics, which weakens them.
