从初一学生的年龄特征和心理特点来看,上好绪论课,对于激发学生的学习兴趣,培养他们科学的学习方法,树立远大理想都有着十分重要的作用。我在上《生物》新教材绪论“探索生物的奥秘”一课时,重视了以下四点 一、设计新颖的导言 上课伊始,我便以趣话“鸡与蛋”开场:据说早在古希腊时代就有人提出是先有鸡还是先有蛋的问题,由于蛋是鸡产的,鸡又是从蛋中孵出的,所以这个问题始终像一只怪圈困惑着人们。接着我又设置了下列几个问题:植物的叶儿为什么是绿的?花儿为什么十分鲜艳?俗言道:“种瓜得瓜,种豆得豆”;而又言: “一母生九子,九子各别。说的各是什么现象?地球上的生物从最低级的细菌病毒到万物之灵的人最初是从何而来的?”通过设置以上悬念,顺势导入新课,向学生说明要解决上述问题,必须具备生物知识。简炼新奇有趣的导入,及时将学生的注意力吸引到课堂上来,使学生积极主动的思考问题,从而唤起了学生获取生物知识的渴望,产生了寻取解决问题钥匙 Judging from the age characteristics and psychological characteristics of the junior students, the good introduction class has a very important role in stimulating students’ interest in learning, cultivating their scientific learning methods and establishing lofty ideals. When I was in the “Biology” new textbook introduction “The Mysteries of Exploring Creatures” lesson, I paid attention to the following four-points. I started with a novel design. At the beginning of my class, I started with the interesting words “chicken and egg”: it is said that as early as the ancient Greek era Some people have raised the question of whether there is a chicken or an egg first. Since the eggs are produced by chickens and the chickens are hatched from eggs, the question always seems like a strange circle confusing people. Then I set up the following questions: Why is the leaf of the plant green? Why is the flower bright? The common saying goes: “Take melons and get beans and beans,” and say: "A mother of nine Nine children are different. What is the phenomenon of each? What did the Earth’s creatures from the lowest level of bacteria and viruses to the spirit of the universe come from?” By setting the above suspense, he introduced the new class to the students. Explain that in order to solve the above problems, you must have biological knowledge. Concise new and interesting introductions, promptly attract students’ attention to the classroom, and enable students to actively think about issues, thereby arousing the students’ desire to acquire biological knowledge and generating the key to finding solutions to problems.
