论文摘要
在本科或高中的教学宇宙学需要简化和类比，不可避免地会使教师与不断扩展的宇宙的至少一种教学解释接触。到目前为止，最受欢迎的解释认为，扩展的宇宙中的星系是静止的，而空间本身则扩展，从而导致越来越多的距离宇宙扩张的距离。替代性相对论爆炸解释将宇宙扩张视为（相对论）星系运动的模式。本文的目的是考虑到有益的锚定概念和可能导致误解的潜在有害的概念，从潜在的学生先入之视的角度讨论两种相互竞争的解释。
Teaching cosmology at the undergraduate or high school level requires simplifications and analogies, and inevitably brings the teacher into contact with at least one of the pedagogical interpretations of the expanding universe. The by far most popular interpretation holds that galaxies in an expanding universe are stationary, while space itself expands and thus causes the growing distances that characterize cosmic expansion. The alternative relativistic explosion interpretation regards cosmic expansion as a pattern of (relativistic) galaxy motion. The aim of this article is to discuss the two competing interpretations from the perspective of potential student preconceptions, taking into account both beneficial anchoring conceptions and potentially harmful preconceptions that can lead to misconceptions.
