良好的开端是成功的一半。巧妙的导入是课堂教学的开端,也是引入新课的艺术再现。良好的导入不仅能够激发学生的学习兴趣,而且能使学生在轻松愉快的气氛中不知不觉地进入新课的学习,从而达到预期的效果。 Well begun is half done. Clever introduction is the beginning of classroom teaching, but also the introduction of a new class of art reproduction. A good introduction can not only stimulate students’ interest in learning, but also enable students to unknowingly enter the new lesson in a relaxed atmosphere so as to achieve the expected result.
