初中学生进入课堂学习之前或学习过程中形成的错误前概念对物理学习有着不容忽视的影响,文章从学生认知发展的角度分析前概念产生的机制,并运用氢原子的能级跃迁现象解释前概念转化教学的困难性,提出基于共振思想的纠正错误前概念的教学策略,并以纠正学生中存在的“近大远小”是平面镜的成像特点这一错误前概念为例进行验证。 The concept of pre-error before or after the middle school students entered classroom learning has a significant impact on physics learning. The article analyzes the mechanism of preconception development from the perspective of students’ cognitive development, and uses the energy level transition phenomenon of hydrogen atoms to explain the The difficulty of the concept transformation teaching, proposes the teaching tactics of correcting the pre-error concept based on the resonance idea, and uses the pre-erroneous concept of correcting the “nearly big and small” which is the imaging characteristic of the plane mirror as an example to verify.
