摘要：Physics education research increasingly makes use of video data for analysis of student learning and teaching practice. Collection of these data is conceptually simple but execution is often fraught with costly and time-consuming complications. This pragmatic paper discusses the development of systems to record and permanently archive audio and video data in real-time. We focus on a system based upon consumer video DVD recorders, but also give an overview of other technologies and detail issues common to all systems. We detail common yet unexpected complications, particularly with regard to sound quality and compatibility with transcription software. Information specific to fixed and transportable systems, other technology options, and generic and specific equipment recommendations are given in supplemental appendices
