一、导入设计引进学生熟悉的生活内容良好的开端是成功的一半。数学教学用学生生活中熟悉的事例来开头,既能成功地导入新课,又能使学生感到亲切产生兴趣,还能培养学生运用数学知识来解决实际问题的能力。如开始教学“相遇问题”时,我先请两名学生分别站在讲台的左侧和右侧,听教师喊“走”之后,两名学生同时相向而行,当两人相遇时喊“停”。问:“这两名同学怎么了?”同学回答:“相遇了。”老师说:“对了,这节课我们就来学习有关相遇问题的应
First, the introduction of design The introduction of students familiar with the content of life A good start is half the battle. Beginning with familiar examples of student life, math teaching can successfully introduce new lessons and interest students, as well as develop students’ ability to apply mathematical knowledge to solve practical problems. When I started teaching “Encounter Problems,” I first asked two students to stand on the left and right sides of the podium. After hearing the teacher shout “Go”, the two students were facing each other at the same time and shouted “Stop ”. Q: “What happened to the two classmates?” The classmate replied: “Encountered.” The teacher said: "Yes, in this class we will learn about the encounter
