一、问题提出元素及其化合物知识属于化学中的基础知识部分,在化学学科中发挥着重要的载体作用,这部分的教学目的是物质的化学性质及方程式的记忆,然而这部分知识庞杂、琐碎,经常出现前学后忘的尴尬局面。因此元素化合物知识成为化学教学的难点之一,也成为影响学生化学学习兴趣的重要因素。如何将这部分知识的学习变成学生易理解、易记忆、感兴趣的内容。笔者以铝及其化合物的性质教学实践归纳出一种有效的教学途径。查阅中国基础教育全文数据库的资料,发现很多有关元 First, the problem proposed elements and their compounds Knowledge is part of the basic knowledge of chemistry in chemistry plays an important role in the carrier, this part of the teaching objective is the chemical nature of the material and equation of memory, but this part of the knowledge of complex, trivial , Often appear before the school forget the embarrassing situation. Therefore, the knowledge of elemental compounds has become one of the difficulties in chemistry teaching and has also become an important factor that affects students’ interest in chemistry learning. How to turn this part of the learning of knowledge into easy-to-understand, easy-to-remember and interesting content for students? The author summed up an effective teaching method based on the teaching practice of aluminum and its compounds. Check the Chinese basic education full-text database, found a lot of relevant yuan
