基于微观粒子运动本质再探核外电子运动的教学设计与实施

Teaching Design and Implementation of Extronuclear Electron Motion Based on the Essence of Microscopic Particle Motion

高中选择性必修阶段对核外电子运动再探究需要在学科理解视域下认识核外电子运动的本质规律。通过原子结构模型的演变过程抽提核外电子运动的本原性问题,在本原性问题解决的学习任务中引导学生发展性地建构原子结构模型。基于微观粒子运动的本质认识核外电子的运动特征和描述方式,建构核外电子运动的微观认识视角。

The re-exploration of the extranuclear electron movement needs to understand the essential law of the extranuclear electron movement from the perspective of disciplinary understanding in the selective compulsory stage of high school.Through the evolution process of atomic structure model,the original question of electron movement outside nuclear is extracted,and the students are guided to construct atomic structure model developmentally in the learning task of primitivism problem solving.Based on the nature of the motion of microscopic particles,the motion characteristics and description of the extranuclear electrons are understood,and the microscopic perspective of the motion of the extranuclear electrons is constructed.
