课堂教学是一个包含教材知识结构,学生认知结构和课堂教学结构的多层次的体系,主要由教师、课程、学生、教学媒体和化学实验这五个元素组成,其中课堂教学结构是课堂教学的主结构,是指在一定的思想理念下,老师为了完成教学目的和任务,通过对教学的各种要素进行设计的固定的教学流程,这是一整套的教学方法体系,也是实施教学的一种重要方法和途径,因此,根据时代的发展、学生认知水平的提高和课堂教学动态化的要求改变传统的化学教学结构模型就显得尤为重要.
Classroom teaching is a multi-level system consisting of textbook knowledge structure, student’s cognitive structure and classroom teaching structure. It consists of five elements: teacher, course, student, teaching media and chemistry experiment. The classroom teaching structure is classroom teaching The main structure refers to the fixed teaching process designed by the teacher to complete the teaching purpose and tasks and the various elements of teaching under a certain ideological conception, which is a set of teaching method system and also a kind of implementing teaching Therefore, according to the development of the times, it is very important to change the traditional model of chemistry teaching structure according to the improvement of students’ cognition level and the requirement of dynamic teaching in the classroom.
