上海市青浦县教师进修学校教研员顾冷沅在一次调查研究中发现,白鹤中学有一位数学教师,不管什么班级交给他,不出数月,其教学成绩准会与同类班级拉开距离,高出一头。效果如此突出,秘诀何在?经过了解,原来这位数学教师的全部秘诀只在一个“快”字:学生做作业快,教师改作业快,发现问题向学生讲授快。通常,教师让学生轮换使用两个练习本,这位数学教师为了加快循环,让学生只用一个练习本。有人怀疑:这也算经验?这也算改革?是的,这也是经验,这也是改革。经过实践取得的知识就是经验,把事物中旧的不合理的部分改变成新的、能适应客观情况的做法就是改革。改革并不神秘,关键在于人们是不是自觉学习并运用科学的理论,并根据实践中得来的知识,对传统的、习惯的思想和行为,大胆地革除其旧弊。 Gu Qingyuan, a researcher at the Qingpu County Teacher Training School in Shanghai, found in a survey that there was a math teacher in Crane Middle School, no matter what class it was given to him. Within a few months, his teaching achievement would be far away from the same class, Overhead. The effect is so prominent, what is the secret? After understanding, the original secret of the mathematics teacher only in a “fast” words: students do homework fast, teachers change homework fast, find problems to teach students faster. Normally, teachers have students switch between two exercise books, which the math teacher uses to speed up the cycle and give the student only one exercise book. Some people wonder: Is this also experience? Is this reform? Yes, it is also experience. It is also a reform. Knowledge acquired through practice is experience, and changing the old irrational part of things into a new one that can adapt to the objective situation is the reform. The key to reform is that people are not consciously learning and applying scientific theories and boldly eradicating the old drawbacks of traditional and customary ideas and behaviors based on the knowledge they have gained in practice.
