导言是上好一节课的关键。对于一节课来说,导言既可以通过上节课的旧知识,引入新知识,又可以为新授课埋下伏笔,设下悬念。它是联系新旧知识的纽带,它在已有知识和新授知识之间架起了一个桥梁。应该说,一节精彩的授课,导言的作用是不可忽略的。它是一节好课的点睛之笔。因此,恰当地选择导言的材料,就显得尤为重要。恰当的导言材料,能够激发学生的学习兴趣,调动学生的学习积极性,发挥学生的主动性和创新意识,并能扩展学生的视野,使新旧知识能够自然衔接,并能顺利地过渡到新授课。
The introduction is the key to a good lesson. For a lesson, the introduction can not only introduce new knowledge through the old knowledge of the previous lesson, but also lay a foundation for new teaching, set up suspense. It is a link between new and old knowledge, and it bridges the gap between existing knowledge and new knowledge. It should be said that a wonderful lesson, the role of the introduction can not be ignored. It is the crowning touch of a good lesson. Therefore, it is particularly important to select the materials of the introduction appropriately. Proper introductory material can stimulate students’ interest in learning, motivate their enthusiasm for learning, give full play to the students’ initiative and sense of innovation, expand students’ horizons, bring new and old knowledge into harmony, and make a smooth transition to new lectures.
