所谓教学难点,是指学生感到难以理解或接受的内容。造成学生数学学习困难常见的原因有知识本身的抽象、复杂导致难以理解,容易混淆且不便记忆、学生相应的能力较薄弱等。数学课堂实现高效就必须突破自主学习中的重难点,找到学习的突破口。数学教学的重要任务之一,就是根据具体教学内容的特点和学生实际,准确确定学生学习中的难点,采取有效措施,帮助学生消除学习中的困难。因而可以说,学生的学习难点即是教师的教学难点。课堂教学中, The so-called teaching difficulties, refers to the students feel difficult to understand or accept the content. Common causes of students’ math learning difficulties are the abstraction of knowledge itself, complexity leads to difficult to understand, easy to confuse and inconvenience memory, the corresponding ability of students is weak and so on. In order to realize the high efficiency of mathematics classroom, we must break through the heavy and difficult points in autonomous learning and find a breakthrough in learning. One of the important tasks of mathematics teaching is to accurately determine the difficulties in student learning based on the characteristics of specific teaching contents and students’ actual conditions and to take effective measures to help students eliminate the difficulties in learning. Thus it can be said that students’ learning difficulties is the teaching difficulty of teachers. In classroom teaching,
