現在中學校裹,數學教學中關於批改數學練習本問題,確是一個嚴重的,亟待研究解决的問題,數學練習本怎樣處理才能費力小而收效大?這就是要研究和討論的重點,如果僅採取了“檢查和抽改”的方法,似乎不够負責的,因為練習本中的錯誤是很多的,想像不到的,不但基本關係和運算上有限多的錯誤,像2(x+5)=2x+5,
Now in the middle school, mathematics teaching is really a serious question about correcting mathematics exercise books. It is urgent to study and solve the problems. How can a mathematical exercise book be handled with less effort and more results? This is the focus of research and discussion, if only The method of “checking and revising” seems to be not responsible enough because the mistakes in the exercise book are many and unimaginable, not only the basic relationship and the operation of a limited number of errors, like 2(x+5)= 2x+5,
