在整个高中化学中,周期律这一章教学的重要性是无庸怀疑的。它是整个教材的理论基础,并且在培养学生辩证唯物主义的世界观方面,也起着极重要的作用。但是,往往由於教师采用教条式的教学,或者学生对起始的20种元素的性质掌握不够,有些学过的也忘了,因此教到这一章时,学生感到难学。或者在学完後印象模糊。有些只知道死记硬背。影响教学质量的提高。去年,当我教到东北版高中化学“元素周期表”这一章时,受到苏联教育部颁发的“中学化学课外作业的指示信”(译文见1953年9月号化学通报)这篇文章的启发,采用了元素性质卡片来进行这一章
The importance of teaching the cycle law throughout this high school chemistry is beyond doubt. It is the theoretical basis of the whole textbook, and plays an extremely important role in cultivating students’ dialectical materialistic worldview. However, it is often difficult for students to teach this chapter because of their dogmatic teaching or because students have not mastered the nature of the first 20 elements and some have forgotten. Or after the learning impression blurred. Some only know rote. Affect the improvement of teaching quality. Last year, when I was teaching the “Elemental Periodic Table of the Northeast High School Chemistry”, I received the “Letter of Instruction for Secondary School Chemistry Extracurricular Work” issued by the Ministry of Education of the Soviet Union (translation, see the September, 1953 Bulletin of Chemistry) Inspired, using the elemental nature of the card to carry out this chapter
