长期以来,在中学化学课堂上,仍然有很多教师采用传统的教学方法,学生在课堂上只能被动接受教师提供的化学知识,此种教学模式限制了学生的自主创新。元素化合物这部分内容是化学学科中非常关键的部分,与其他理论知识相互配合,是学生养成元素观、变化观等观点的关键,同时也是掌握基本化学概念的载体。但元素化合物内容知识较多,涉及的化学现象与化学反应也不太容易掌握,很容易导致思维混乱,在解决问题时
For a long time, there are still many teachers in traditional chemistry teaching in middle school chemistry class, in which students can only passively accept the chemical knowledge provided by teachers. This kind of teaching mode restricts students’ independent innovation. Elemental compounds This part of the chemical discipline is a very critical part of the interaction with other theoretical knowledge is the concept of students to develop elements of the concept of change is the key point, but also master the concept of basic chemistry carrier. However, the content of elemental compounds more knowledge, involved in chemical reactions and chemical reactions are not easy to grasp, it is easy to lead to confusion thinking, in solving problems
