在生物学实验教学中,如何指导学生很好地完成实验内容,培养学生的生物学实验技能,可以有多种不同的方法。第一种是讲解法,即教师只用言语解释不做示范动作,学生静听后自行实验与练习。第二种是讲解示范法,即教师先用言词解释后做示范动作,学生听、观后自行实验与练习。第三种是边讲解边示范和回答问题法,即教师一边用言词解释,一边做示范动作,讲一步做一步,学生听、观后进行实验与练习,学生在实验与练习过程中,提出疑难问题,教师可随时给予解答。第四种是边讲解边示范,引导学生同步实验和纠正错误法,即教师一边解释,一边示范,每做一步让学生完成一步,直至将该实验操作一遍,然后让学生练习,教师巡回纠正学生练习中出现的错误。本试验是笔者在上海市云岭中学教学实习中提出的,目的是比较四
In biology experiment teaching, how to guide students to finish the experiment content well and train students’ biology experimental skills can have many different methods. The first method is to explain the method, that is, the teacher only uses the words to explain and not to perform the demonstration. The students will try and practice their own experiments after listening. The second is to explain the model law, that is, teachers first use the words to explain and then do demonstrations. The students will listen and observe and practice their own experiments. The third method is to explain and answer the question method while the teacher is using the words to explain, while doing demonstrations, step by step, the students to listen to and observe the experiment and practice, the students in the process of experiment and practice, difficult Problems can be answered by teachers at any time. The fourth is to explain the lesson while demonstrating and guide students to synchronize experiments and correct mistakes. That is to say, the teacher explains while demonstrating one step. Each step is done to let the student complete one step, until the experiment is performed again, and then the students are allowed to practice. The teacher tours to correct the students. Errors in practice. This experiment was presented by the author during the teaching practice at Yun Ling Middle School in Shanghai. The purpose is to compare four.
