减负增效背景下化学教学要转变传统的教学模式,构建新的中学化学教学模式,从而提高课堂教学的有效性,促进学生的全面发展。基于现代建构主义理论,探究减负增效背景下化学实验教学情境的创设及其功效。
In the background of reducing the burden and increasing the efficiency, the chemistry teaching should change the traditional teaching mode and construct a new chemistry teaching mode in the middle school so as to improve the effectiveness of classroom teaching and promote the all-round development of students. Based on the theory of modern constructivism, this paper explores the creation and effectiveness of the chemistry experiment teaching situation under the background of reducing the burden and increasing efficiency.
