论文部分内容阅读
新颖的题目是中学数学教学不可或缺的基本素材,也是广大一线教师孜孜搜求的稀缺资源.什么是新题?似乎不大好下定义,但我们一线的老师又都心知肚明.我们以为,“新”题是相对“旧”题、相对传统题目而言的,无论是题目的背景,题目的解法,还是题目的价值(思维价值、教学价值、训练价值),只要有不同于传统题目之处,都可以纳入我们此处的关注范畴.本栏目将每期刊登6道题目,人教版,北师大版,华东师大版七、八年级各一道,内容尽量保持与教学同步,希望对广大读者有所帮助,也欢迎大家为本栏目踊跃撰稿.
The novel subject is the basic material that is indispensable for middle school mathematics teaching. It is also a scarce resource for the vast number of front-line teachers. What is a new question? It seems that it is not well defined, but our front-line teachers are all well aware. We think, The “new” question is relative to the “old” question, as opposed to traditional questions, whether it is the background of the question, the solution of the question, or the value of the question (thinking value, teaching value, training value), as long as it is different The traditional topics can be included in our focus here. This column will publish 6 topics per issue, PEP, Beijing Normal University, and the 7th and 8th grades of East China Normal University. The teaching is synchronized, and it is hoped that it will help the readers. We also welcome you to contribute to this column.
