江苏高考将物理选修模块3-3、3-4、3-5定为选考内容,要求考生在这3个模块中任选2个模块作答.绝大多数的学校都选了3-3、3-5模块,原因是3-4模块得分率普遍不高.这给广大教师带来了较大的麻烦,因为模块3-5中的很多内容都与模块3-4内容有关,如3-4中的干涉、衍射、偏振等波动规律,若不讲授学生很难理解3-5中的光子和实物粒子的波动性;再如3-4中的电磁波谱(特别是在可见光区域附近)中各部分波长或频率的大小关系及它们各自的特性等知识,在3-5中均要用到.在知识模块化的背景下,淡化了模块间的联系造成前后知识脱节,难以形成系统,学生学起来吃力,教
Jiangsu college entrance examination of the physical elective modules 3-3,3-4,3-5 as the exam content requirements of candidates in these three modules optional 2 module answers.Most schools have chosen 3-3, 3-5 modules, because 3-4 module score rate is generally not high.This has brought a lot of trouble for the majority of teachers, because a lot of content 3-5 modules are related to the content of the module 3-4, such as 3- 4 in the interference, diffraction, polarization and other fluctuations, if you do not teach the students difficult to understand the photons 3-5 and the physical particle fluctuations; again 3-4 in the electromagnetic spectrum (especially in the vicinity of the visible light) The relationship between the size and wavelength of each part or the frequency and their respective characteristics and so on are all used in 3-5. Under the background of knowledge modularity, the relation between modules is weakened, which leads to the disconnection between knowledge before and after, Learn hard to teach
