论文部分内容阅读
高中二年级第八章光的本性第九章原子和原子核一、教学变动情况这两章教材与原课本相比,只在以下几方面有小的变动。第九章有三处原课本上打*号的选修部分现改为必修,即第二节的“能级”部分,第九节和第十节的前半部分,另有原课本中必修的第三节的前半部分(玻尔理论对氢光谱的解释)现改为选学,总的意图是在不过多加重学生负担的情况下加强关于原子和原子核能量部分的教学。练习题部分,第八章练习二及本章末的习题中各增加两个基本练习题,各删去一个选做题,被删去的选作题内容涉及正文中选学部分的知识,并且与以前学过的内容相联系,删去的目的显然是告诉我们,即使给学生讲授选学部分的内容,也不必让学生做难度较大
The eighth chapter of the second grade of high school The nature of light The ninth chapter of the atom and the nucleus First, teaching changes The two chapters of the textbook compared with the original textbook, there are only minor changes in the following aspects. In the ninth chapter, there are three elective parts of the original textbooks marked with *, which are now compulsory, that is, the “energy level” section in the second quarter, the first half of the ninth and tenth sections, and the third required in the original textbooks. The first half of the festival (Bohr theory’s interpretation of the hydrogen spectrum) is now changed to elective. The general intention is to strengthen the teaching of the atomic and nuclear energy part without overburdening the students. In the exercises section, in Chapter 8 Exercise 2 and in the exercises at the end of the chapter, two basic exercises are added. Each of the selected exercises is deleted. The selected topic is related to the knowledge of the selected part of the text, and is related to the previous The contents studied are related. The purpose of the deletion is obviously to tell us that even if students are taught about the content of the selection part, they do not have to make it difficult for students to do it.
