Modelling in physics teaching via stop motion production with the Raspberry Pi compute

Abstract In this work we present a cost effective apparatus for producing frame by frame animation (stop motion) as a didactic tool for Physics teaching. The apparatus dedicated to capture and exhibit stop motion is built with a Raspberry Pi computer and has an interface which allows students to a simplified handling and to an immediate playback of the modeled results. We review different tools for modeling dynamic situations and we also present characteristics that make advantageous the usage of stop motion on Physics teaching. We draw a short historical landscape of frame by frame animation and then we describe in detail how to build the apparatus and how to install a custom dedicated software we developed, in order to enable its replication and use in Physics classrooms.

摘要 本研究提出一款经济实用的逐帧动画（stop motion，定格动画）制作装置，作为物理教学的演示教具。该专用于定格动画拍摄与展示的装置基于树莓派（Raspberry Pi）计算机搭建，配备简化操作的交互界面，可让学生便捷操作并即时回放建模所得结果。本文梳理了多款用于动态场景建模的工具，并阐述了定格动画应用于物理教学的显著优势。随后，本文简要梳理逐帧动画的发展简史，详细介绍该装置的搭建步骤，以及我们开发的定制专用软件的安装方法，以期为该装置在物理课堂中的复制与应用提供便利。
