指向模型建构能力培养的高中物理BOPPPS模式教学设计研究——以“带电粒子在匀强磁场中的运动”为例

Research on BOPPPS Model Teaching Design for High School Physics Focusing on Model Construction Ability Cultivation—Taking “The Motion of Charged Particles in a Uniform Magnetic Field” as an Example

摘要: 在高中物理教学中，培养学生对问题进行模型建构的能力，是发展学生科学思维核心素养的重要途径之一。本文以“带电粒子在匀强磁场中的运动”为载体，基于BOPPPS教学模式开展教学设计，构建“情境感知–模型抽象–数理表征–迁移应用”的模型建构能力培养教学路径，并将教学设计用于教学检验效果。本文认为，BOPPPS的六个环节能够为物理中模型建构教学提供环节支持，初步实施也表明这种教学设计能够有效提高学生对物理问题的模型建构能力，但在实施过程中需灵活处理线性环节与建模思维非线性迭代之间的张力。本文中的教学设计为高中物理建模教学提供了可操作的范例。

Abstract: In high school physics teaching, it is one of the important ways to develop their core scientific thinking literacy by cultivating students’ ability of model construction for problems. This article takes “the motion of charged particles in a uniform magnetic field” as the carrier and carries out a teaching design based on the BOPPPS teaching mode, constructing a teaching path for cultivating model construction ability that is “situational awareness-model abstraction-mathematical representation-transfer application”, and testes the effectiveness of the teaching design through teaching. This article argues that the six links of BOPPPS can provide link support for model construction teaching in physics. The preliminary implementation also shows that this teaching design can effectively improve students’ ability to construct models for physical problems. However, in the implementation process, it is necessary to flexibly handle the tension between linear links and nonlinear iteration of modeling thinking. The teaching design in this article provides an operable example for high school physics modeling teaching.
