“前概念”干扰是构建新概念的主要思维障碍,需要运用批判性思维的策略加以排除.物理思维具有高度的批判性,既是高中物理学习的重要基础,也是学生形成优秀思维品质的必要基础.在“加速度”教学中,引导学生对相似“前概念”进行反思,提练物理思想方法,进行思维能力的训练,促进学生的批判性思维意识的提升. Disturbance is a major obstacle in thinking to construct a new concept and needs to be excluded by using a critical thinking strategy.Physical thinking is highly critical and is not only an important foundation for high school physics learning but also a necessary for students to form good thinking quality In the teaching of “acceleration”, students should be guided to reflect on similar “preconceptions”, to train students in thinking skills through physical thinking and to promote their critical thinking.
