人教版新编九年义务教材《中国历史》第1册第1课,在现行教材的基础上,增设了“怎样计算年代”这个知识点。年代计算是学生必须具备的一项基本技能。新教材把这一知识编写进教材,既利于学生加强记忆、掌握历史知识,也利于减轻教师教学头绪。但是,在新教材的试用过程中,有的老师和部分学生,对教科书中年代尺的表示方法、年代和世纪的定义以及教师教学用书中年代的计算方法,有一些不同看法,纷纷给教科书的编著者写信询问。下面,就这一问题谈谈本人的几点看法。 People’s Education Edition New compilation of nine-year compulsory teaching materials “Chinese history” first book first class, based on the existing teaching materials, an additional “how to calculate the age” of this knowledge. Calculation of age is a basic skill a student must possess. The new textbook compiles this knowledge into teaching materials, which not only helps students to strengthen their memory, grasp historical knowledge, but also help reduce the teaching clue of teachers. However, during the probationary process of new textbooks, some teachers and some students have different opinions on how to represent the chronology of textbooks, the definition of age and century, and the calculation method of the age of teachers’ teaching books. Writers write to ask. Below, talk about my own views on this issue.
