俗话说“良好的开端等于成功的一半,”教学何其不是如此。就说一堂40分钟的课,怎样开好头,揭示课题,导入新课,是课堂教学的重要一环。有经验的教师非常重视导入新课的艺术性,他们往往运用“悬念”的手法,造成学生渴望、追求新知的心理状态,激发学生的兴趣,起到一石激起千层浪的良好效果。但也有不少教师忽视新课的导入工作,新课的提出有的只是吹皱了一池春水,余波甚微,有的甚至毫无余波。这样,便不能调动学生学习积极性。针对这一情况,本文想列举数例说明运用“悬念”导入新课的方法及其作用。
As the saying goes, “a good start is equal to half the success,” teaching is not the case. Speaking a 40-minute class, how to make a good start, reveal the topic, the introduction of a new lesson is an important part of classroom teaching. Experienced teachers attach great importance to the artistry of introducing new lessons. They often use the technique of “suspense”, causing students to desire, pursue the psychological state of new knowledge, stimulate students' interest and play a good role in provoking a wave of waves. However, many teachers have neglected the introduction of the new course. Some of the new courses just blow out a pool of spring water with a small aftermath and some even have no afterthoughts. In this way, we can not arouse the enthusiasm of students. In response to this situation, this article lists a few examples of the use of “suspense” into the new lesson method and its role.
