生本教育理念下的化学实验教学是一种全新的教学模式,无论备课、上课还是评价反思,都重视学生的存在,突显其主体地位,实现了实验课堂教学的新跨越。鉴于化学实验教学的特殊性,生本理念下该如何实施实验教学呢?一般情况下,化学实验课堂教学模式可分为五个阶段:第一阶段:设定前置性作业,奠定实验理论基础生本教育提出的教学原则是:先学后教,以学定教。“先学后教”就是通过学生先学习,确定课堂教学的起点。学生先学的内容一般被称为“前置性 The experiment teaching under the concept of students’ education is a brand new teaching mode. Regardless of lesson preparation, class or evaluation, all emphasize on the existence of students, highlighting the dominant position and realizing a new leap in experimental classroom teaching. In view of the particularity of chemical experiment teaching, how to implement experimental teaching under the concept of student-centered philosophy? Under normal circumstances, the teaching model of chemical experiment classroom can be divided into five stages: The first stage: setting the pre-operation, laying the foundation of experimental theory The principle of teaching proposed by students is that they should learn first and then learn to teach. ”First learn after teaching “ is to learn through the students, to determine the starting point of classroom teaching. Students learn the content is generally known as ”pre-emptive
