新课导入是指通过教师创设的教学情境,帮助学生在接受知识前做好心理上、知识上必要准备的一种教学活动。俗话说:“良好的开头是成功的一半。”有效的新课导入能集中学生的注意力,使之明确思维方向,激发学习兴趣,引起内在的求知欲望,使学生在学习新知识的一开始便有一个良好的开端,为接下来的学习做好准备。每节课的导入设计是否恰当, The introduction of new classes refers to teaching activities created by teachers to help students prepare for psychological and intellectual preparation before accepting knowledge. As the saying goes: “The beginning of good is half of success.” The introduction of effective new lessons can focus students’ attention, make them clear the direction of their thoughts, inspire interest in learning, and create internal desire for knowledge so that students can learn new knowledge. There is a good start from the beginning, ready for the next study. Is the introduction design of each class appropriate?
