化学是职业高中教学的一门基础性学科,且学生在校时又要注重职业技能的形成,这就意味着职业高中的化学教学与普通高中的化学教学有着质的不同。一方面需要通过化学知识的传递去提升学生的化学素养,另一方面都没有必要积累太过丰富的化学知识。这就给职业高中化学教学提出了新的更高的要求,即化学教师要通过自身的化学教学,让学生拥有化学观念并使其为学生的专业学习服务。所谓化学观念,是指化学学习过程中形成的关于结 Chemistry is a basic discipline in vocational high school teaching, and the students pay attention to the formation of vocational skills when they are in school. This means that there is a qualitative difference between chemistry teaching in vocational high schools and chemistry teaching in ordinary senior high schools. On the one hand, chemical knowledge needs to be passed to enhance the students’ chemical quality, on the other hand, there is no need to accumulate too rich chemical knowledge. This puts new and higher requirements on chemistry teaching in vocational high schools, that is, chemistry teachers should pass their own chemistry teaching to let students have the chemical concept and make them serve students’ professional learning. The so-called chemical concept, refers to the chemical learning process formed on the knot
