以开放教育新理念为指导思想,酸碱中和反应为基础,介绍了在中等职业学校化学与实验课程教学中,充分发掘现有教学资源,开设以实用性和探究性为主的酸碱滴定分析开放性实验课题的设计方法,讨论了在中等职业学校化学实验教学中开放性实验的组织和实施策略。 Taking the new concept of open education as the guiding ideology and the acid-base neutralization reaction as the foundation, this paper introduces that in the teaching of chemistry and experiment in secondary vocational schools, we should make full use of existing teaching resources and set up acid-base titration which is mainly practical and exploratory This paper analyzes the design method of open experimental subject and discusses the organization and implementation strategy of open experiment in chemistry experimental teaching in secondary vocational school.
