鲁教版初中化学教材在山东省使用的这几年时间里,作为一线教师的我们对其不断地学习、解读和挖掘,觉得收获颇丰,尤其是对“化学变化”的教学研究,本人发现它在教材中有着很重要的教学价值。一、“化学变化”在教材中的安排“化学变化”贯穿在鲁教版化学教材始末,从了解生活中存在的化学变化实例来认识“化学变化”这个概念、从实质、物质组成、结构等方面深化理解“化学变化”、从质量守恒定律角度定量研究认识“化学变化”实质、再到人为控制
In the past few years, Shandong Province, as a first-line teacher, we constantly learned, interpreted and tapped the chemistry teaching materials of the Shandong-based version of the textbooks of the Shandong-based version of the textbooks. We think it is a rewarding achievement especially in teaching and research on “chemical changes” I found it in the teaching material has a very important teaching value. First, the “chemical changes ” in the textbook arrangement “chemical changes ” throughout the textbooks in chemistry teaching, from the understanding of the chemical changes in life examples to understand “chemical changes ” concept, from the essence , Material composition, structure, etc. to deepen understanding of “chemical changes”, from the perspective of the law of conservation of mass quantitative understanding of “chemical changes” essence, and then to artificial control
