现在老师们习惯将依据“课标”编写的教材称之为课标教材,而将过去依据“教学大纲”编写的教材称之为大纲教材。笔者经历过这两种教材的小学数学教学。课标教材对大纲教材作了较大的修改,以下三个知识点(以下称“二规律一性质”)课标教材就从语言表述上作了修改:教材的以上修改引起了老师们的关注和思考,主要看法有两种:1.有的认为大纲教材的表述没有错,没有必要修改,修改后还易引起多种不同说法的混乱。在大纲教 Teachers are now accustomed to teaching textbooks written on the basis of “class standard” as the standard textbooks, whereas the textbooks written in the past based on the “syllabus” are called outline textbooks. I experienced these two textbooks in primary school mathematics teaching. The standard textbooks have been greatly revised. The following three knowledge points (hereinafter referred to as the “two laws and a nature”) have been revised from the language description. The above revisions of the textbooks have caused the teachers , There are two main opinions: 1. Some people think that the outline teaching material is not wrong, there is no need to modify it, and it is still easy to cause confusion of many different opinions after the revision.
