“转轴拨弦三两声,未成曲调先有情”。美妙的音乐弹奏需要情感蓄势,精彩的课堂生成需要艺术导课。一堂成功的化学课,一定要在“导”字上下功夫。教师欲使学生在不知不觉中产生兴趣,并能用一种魔力启迪学生的心智,就必需精心设计课堂教学的导语,使学生尽早进入学习的最佳状态,积极主动地探究化学科学。课堂导入方法很多,如直接导入法、实验 “Pillow string thirty-two sound, not the first melody”. Wonderful music needs emotional preparation, wonderful classroom generation needs art guide lesson. A successful chemistry class, must be in “guide ” word work hard. Teachers want to make students unknowingly interested, and can use a kind of magic to inspire students’ minds, we must carefully designed classroom teaching guide, so that students enter the best state of learning as soon as possible, and proactively explore chemical science. Many ways to introduce the classroom, such as direct import method, experiment
