最近,很多学校都学习苏联先进经验,实行了“边讲边实验”教学法。这种方法具有很多优点,受到广大学生的热烈欢迎;这种方法对提高教育质量、培养学生实验技能技巧,贯彻基本生产技术等方面,都起着重要的作用。但是,突行这种教学法也存在着一些困难,最大的困难就是准备实验的问题。因为实行“边讲边实验”,教学法,在每节课差不多都有学生实验。而且学生实验要分25组以上进行,(每两人一组。如果人多了做实验时学生就要离开座位,影响课堂秩序)每一个班就要准备25份以上的仪器,药品。如果一天有三个班上课,突验的准备工作就成了大问题。最初,我们学校既没有实验室管理员,又没有供讲 Recently, many schools have learned the advanced experience of the Soviet Union and implemented the “teaching by lecturing while teaching” method. This method has many advantages and is warmly welcomed by the majority of students. This method plays an important role in improving the quality of education, training students’ experimental skills and implementing basic production techniques. However, there are also some difficulties in this teaching method. The biggest difficulty is the problem of preparing experiments. Because of the “edge of the experiment”, teaching method, almost every class has a student experiment. And the students experiment should be divided into 25 groups or more, (every two people in a group.If more people to do experiments will leave the seat, affecting the classroom order) Each class will have to prepare more than 25 instruments, medicines. If there are three classes a day class, the preparation for the test becomes a big problem. Initially, our school neither laboratory manager, did not say
