【案例一】(源自2012年习水县教师考学(初中)数学试卷)某节市级数学评优课,课题是《用方程组解决问题》(第一课时),有位老师是这样做的:他自编了三道题并用当前最火的动画片《喜羊羊和灰太狼》中的灰太狼和红太狼的一段对话,串起三道应用题,让一名同学戴上灰太狼的头套扮演灰太狼,一名同学戴上红太狼的头套扮演红太狼,每逢问题的呈现,两位同学就站起来学着灰太狼和红太狼的声调来对话,并引出问题,凡是答对问题的同学都能得到老师精心准备的奖品,结果全班同学学习积极性大增,纷纷举手要求发言,课堂气氛也非常热烈。请对该课例作出分析。
Case 1 (from the 2012 Xishui County teacher examination (junior high) mathematics papers) a city-level mathematics assessment class, the subject is “to solve the problem with equations” (the first class), a teacher is like this He wrote three questions and made three dialogues with a series of dialogues between Big Wolf and Red Wolf in the current hottest animated film “Pleasant Goat and Big Big Wolf,” so that a classmate wore a wig Gray Wolf, a classmate wearing Red Wolf’s headdress plays the Red Wolf, every problem appears, the two students stood up and learned the sounds of Big Wolf and Red Wolf to dialogue, and leads to problems, those who answer the question students Can get the prizes carefully prepared by the teacher. As a result, the students in the class have greatly increased their enthusiasm in learning and have raised their hands to speak. The classroom atmosphere is also very warm. Please analyze the lesson.
