這篇文章是某砲兵速成中學一位數學教師的教學經驗。普通中學是不可能進行這樣多的數學練習的。但是,這篇文章中所提到的系统地聯貫地佈置習題的經驗,以及在各個教學階段對不同程度的學生採取幾種練習的經驗,都很值得我們中學的數學教師參考。我們的經驗證明,在數學教學中為要培養學生的思考力及善於運用既有知識於實践的技能與熟練技巧,必须發揮教師的主導作用,認真地、正確地組織、指導學生做練習。在這裏,如系统地聯贯地佈置練習,正确掌握練習題的深淺、難易和複雜程度,保證練習題和練習方式的多樣性等等,都是教師應該注意掌握的問題。现在,把我自己在這些方面的一些粗淺的認識介紹出來,希望同志們指正。 (5)周教员有人民幣七萬元,他以五分之一的錢買筆記本,又用剩下的四分之三買鋼筆,問他買鋼筆用去多少元? (6)問他還剩多少元? 全班四十五人在三十分鐘內都正確地作出了所有的答案。最後一個問題,全班共列出了八種不同的算式:
This article is a teaching experience for a math instructor at a middle school schooler. Ordinary high school is impossible for such a lot of math exercises. However, the experience of systematically and systematically arranging exercises mentioned in this article, as well as the experience of exercising several exercises at different levels of students in all stages of teaching, is well-suited to our secondary school mathematics teachers. Our experience proves that in mathematics teaching, in order to cultivate students’ thinking ability and skills of applying existing knowledge in practice, we must play a leading role of teachers and conscientiously and correctly organize and guide students to practice. Here, it is a problem teachers should pay attention to systematically and practically arranging exercises, correctly understanding the depth, difficulty and complexity of exercises, and ensuring the diversity of exercises and exercises. Now, I will introduce some of my superficial understanding in these areas and hope that the comrades will correct me. (5) Week teacher has 70,000 yuan, one fifth of his money to buy a notebook, but also with the remaining three quarters to buy a pen and asked him how many dollars to buy a pen? (6) Ask him left How Many? The forty-five members of the class correctly made all the answers in thirty minutes. The last question, the class lists a total of eight different formulas:
