课堂教学是一门艺术,而课堂导语更是艺术中的艺术,“转轴拨弦三两声,未成曲调先有情。”一个好的开头是师生间建立感情的第一座桥梁,它既能引起学生的兴趣,又能激发学生的求知欲,为整节课的学习打下良好的基础,使整个教学活动进行得生动、活 Classroom teaching is an art, and classroom instruction is more of an art in art. “The shaft is plucking three or two strings and not being tuned first.” A good beginning is the first bridge between the teacher and the students to build feelings. It can not only arouse the interest of students, but also stimulate students’ curiosity, lay a good foundation for the study of the whole class, and make the whole teaching activity lively and alive.
