每一节数学课的教案,都有一个课题。数学课题一般在每节课的开头几分钟内告诉学生。而用什么方法告诉学生,则是一种艺术。数学课题的引入方法较多,这里仅就常用的“开门见山”、“豁然开朗”谈谈体会。所谓“开门见山”,即是教师上课时,直接向学生宣布本课课题,并用简明的语言介绍本节课的安排程序,然后按照预先拟定的课时计划进行教学。这种方法干脆利落,节省时间,容易发挥教师上课的主导作用。上练习课、复习课常用这种方法。
Each section of math lesson plans, there is a problem. Math topics generally tell students within minutes of each lesson. What is the way to tell students, it is an art. There are many ways to introduce math problems, just to talk about the commonly used “straight to the point”, “suddenly”. The so-called “straight to the point,” that is, teachers in class, the students directly to the announcement of the subject, and a concise language to introduce the arrangements for this lesson, and then follow the pre-defined lesson plans for teaching. This method altogether neat, save time, easy to play the leading role of teachers in class. On the practice class, review class commonly used this method.
