教学情景有着“情”与“境”并列的两种涵义;创设适当的教学情景导入新课具有吸引学生注意、激发学生学习兴趣,建立学生新、旧知识、经验的联系、激活学生思维、丰富学生经验,改善学习方式等作用;导入新课适用于新授课、探究课、复习课乃至习题课等常见课型;导入新课的方式是多样的,还有待我们大胆创新和不断探索。 The teaching scenario has two meanings of “emotion” and “landscape”; creating appropriate teaching scenes to introduce new lessons attracts students’ attention, stimulates students’ interest in learning, establishes new and old knowledge of students, links with experience, activates students’ thinking, and enriches Student experience, improvement of learning methods, etc.; introduction of new lessons for new classes, inquiry classes, review classes and even exercises and other common classes; introduction of new courses are diverse, yet we have to boldly innovate and explore.
