论文部分内容阅读
通过通报的介绍,与友校的经验,我们于大前年举行了一次复习展览。以后每学期按期举行,并在平日选定一些专题作展览,陈列在图书馆的阅览室,与实验室门前通路上。如酸,硷,盐性质比较,金属非金属标本,煤,石油等专题。在摸索过程中,首先是贪多,选好看的,整套的多排,以致内容分散。以后又过于简略。首先是安排实验,再考虑给予思考题。后来是整理综合成为几个项目,分别拟具思考题,再研究陈列些什么东西。每次进行筹备计划性逐渐加强,考虑的问题也比较集中。(1)准备复习展览的陈列,应在钻研教材的基础上,明确重点,选择主要教材,和能说明本质的实验装置和直观教具。只有掌握化学教材的理论体系,才能给予同学生系统的巩固的科学知识。从卤素到硫氮碳
Through the introduction of the briefing and the experience of our school, we held a review exhibition in the year before. After each semester on schedule, and in the week to select a number of topics for exhibitions, display in the library reading room, and laboratory access in front. Such as acid, alkaline, salt nature comparison, metal non-metallic specimens, coal, petroleum and other topics. In the process of exploration, the first is more greedy, select the right-looking, the whole set of multi-row, resulting in fragmented content. After too brief. The first is to arrange experiments, and then consider giving questions. Later, it was to organize the project into several projects, each with its own questions for study and then to study what was on display. The planning of each preparation gradually strengthened, the issues considered are also more concentrated. (1) To prepare for the review of the display of the exhibition, a clear focus should be made on the basis of the study of the teaching materials, the selection of the main materials, and the experimental apparatus and visual aid capable of illustrating the essence. Only by grasping the theoretical system of chemistry teaching materials can we consolidate the scientific knowledge of students systematically. From halogen to sulfur nitrogen
