在日常课堂教学中,如何才能增强学生的新鲜感,激发学生的学习兴趣,使学生在较短的时间内进入学习状态,课题引入是一个十分重要的环节。课题引入的质量,直接影响到一节课的教学效率和教学效果。如何进行课题引入,传统的做法是在备课时进行充分的设计,有的教师甚至还写了短小文稿,在上课时背诵来导入新课题。我们曾经也这样做过,可在多年的课堂教学中,发现这样做有许多缺陷。如,同一个“引入”对于不同的班级不一定都是适用的;用设计好的情景引入,有时与教室中的情景不相宜,本来 In the daily classroom teaching, how can we enhance the freshness of students, inspire students’ interest in learning, and enable students to enter the learning state in a relatively short period of time. The introduction of the topic is a very important part. The quality of the topic introduced directly affects the teaching efficiency and teaching effect of a class. How to introduce the topic, the traditional approach is to fully design when preparing lessons, and some teachers even wrote a short presentation, in the class to recite the introduction of new topics. We used to do the same thing. In many years of classroom teaching, we found that there were many defects in doing so. For example, the same “introduction ” may not be applicable to different classes; it is introduced with a well-designed scenario, sometimes unsuitable for situations in the classroom.
