【摘要】 传统大学物理实验的考核与评价主要依靠书面考试和教师观察,评价效率低,忽视实验过程,难以全面客观的评价学生实验.本文设计了一种实验过程的视频与实验数据同步记录系统,介绍系统设计、系统实现并以RLC串联电路实验为例介绍系统的应用.实验视频和数据记录为实验评价提供全面、客观的评价依据,通过对实验数据的可视化呈现、数据分析、实验细节的视频和数据联动检索,提高实验评价效率和科学性.更多还原

【Abstract】 Traditional assessment and evaluation of physical experiments relied mainly on the paper examination and teachers’ observation,which was considered to be low efficiency and have ignored the experiment process.So it was difficult to evaluate the overall experiment objectively.An synchronized video and data acquistion system was designed to record the whole experiment process.The system design and its implementation were described.As an typical example,such system was applied to the RLCseries circuit experiment.Experiment video and data record provided a comprehensive and objective basis for the experiment evaluation.The visualization of experiment data,data analysis,detailed experiment data and video retrieval could achieve diversified evaluation of the experiment,improve the efficiency and then lead to scientific evaluation.更多还原
