课堂教学是学校教学的基本形式,上好每堂课是提高各科教学质量的关键。我们围绕改进化学课堂教学这一中心环节,选定《氢气的性质和用途》这节教材为研究对象,开展了一系列的研究活动,并用电视录象手段记录研究的全过程,想为高效率地培养合格的化学教师做点探索工作。初三化学课本第二章第三节《氢气的性质和用途》这段教材,不仅涉及具体物质和基本概念这两类最重要的典型化学教材,而且是初中化学教学中的一个难点。如果未来的中学化学教师在高师学习期间,具有驾驶这种教材的教学能力,那么,处理其他类似 Classroom teaching is the basic form of school teaching, every class is a key to improving the quality of teaching in all subjects. We focus on improving the central part of chemistry classroom teaching, selected “hydrogen nature and use of” textbook as the research object, launched a series of research activities, and video recording means the whole process of research, want to be efficient To train qualified chemistry teachers to do some exploration work. The third day of the third chemical textbook “The nature and use of hydrogen” This textbook, not only involves the specific material and the basic concepts of the two most important types of typical chemical textbooks, and chemical teaching in junior high school is a difficult point. If future high school chemistry teachers have the teaching ability to drive this textbook while studying in higher normal school, then dealing with other similar
