新课程标准下,要提高课堂的学习效率,课前预习必不可少。通过预习可以让学生大致了解新课的内容,重难点,从而更有针对性的进行学习,提高学习效率。然而,只有让学生拥有良好的数学预习习惯,才能更好的发挥学生的主动性、创造性,才能更好的配合课堂教学。因此,教学中,教师必须重视数学课前预习的有效实施。 New curriculum standards, to improve classroom learning efficiency, pre-class preview is essential. By previewing students can make a general understanding of the contents of the new class, heavy and difficult, so as to more targeted learning, improve learning efficiency. However, only by allowing students to have good math prep learning habits can students' initiative and creativity be better displayed in order to better cope with classroom teaching. Therefore, teaching, teachers must pay attention to the effective implementation of math class preview.
