在课堂上,常常会出现意外:教师说错话、写错字、记错公式,学生偶尔会做小动作等等。虽说这些都是小事,但它来的突然,教师如果不及时巧妙处理,容易陷入被动局面。如何巧妙处理,下面几例值得借鉴。一、巧借提问渡难关数学教师王老师在上“和差化积”这一节课时,先将公式写在黑板上,正准备讲课,发现学生在交头接耳、小声议论。王老师再一看黑板,心一下提上来,原来自己将四个公式的系数全写错了。此时自己改吧,有失面子,而不改又不行。在这节骨眼上,王老师讲话了:“上节课我们讲解了和差化积的四个公式,同学们还能记住吗黑板上的公式对不对请李莉同学来回
In class, accidents often occur: teachers make mistakes, write typo, remember formulas, students occasionally make tricks and so on. Although these are small things, but it came suddenly, if teachers do not promptly clever treatment, easy to fall into a passive situation. How cleverly handled, the following few examples worth learning. First, the clever question by cross the difficulty of mathematics teacher Wang on the ”and the difference plot “ This lesson, the first formula is written on the blackboard, is preparing to lecture, found that students whispering, whispering. Wang again look at the blackboard, heart to mention it, the original four coefficients of the formula all the wrong. At this point to change it, lose face, but not change it. At this juncture, Teacher Wang talked: ”In the last lesson, we explained four formulas of difference product, can students still remember the formula on the blackboard?
