摘　　要：密立根油滴实验室高校大学物理实验中具有重要意义的实验,目的在于测量元电荷的数值,实验设立旨在培养高校学生创新性的科研思维和严谨的科学态度。立足于目前密立根油滴实验的教学现状,本文提出一种基于“线上—线下”双模式结合的密立根油滴实验教学方法,首先通过线上实验预习平台,学生自主进行实验的学习和演练。然后线下实验授课平台重点讲解实验原理、实验注意事项和实验数据的处理,充分培养学生的自主学习能力和动手能力。此外,本文创新性地提出一种“误差反馈剔除法”对实验所测的数据进行处理,此方法对受干扰的测量数据具有极强的鲁棒性,实验证明相比原有的倒推法,采用剔除法处理数据后实验的精度有较大的提升。Millikan Oil Drop experiment is of great importance in the university laboratory course,setting up to measure the numerical value of elementary charge.The experiment aims to cultivate the innovative scientific research thinking and rigorous scientific attitude of students.Based on the current teaching status,this paper proposes a Millikan oil drop experiment teaching method based on the combination of"online-offline"dual mode.Firstly,students can independently learn and practice the experiment through the online experiment preview platform.Then,the offline experimental teaching platform focuses on explaining the experimental principle,experimental matters for safety notes and experimental data processing,so as to fully cultivate students'independent learning ability and hands-on ability.In addition,this paper innovatively proposed an"error feedback elimination method"to process the measured data in the experiment.This method has a strong robustness to the interfered measurement data.Experiment show that,compared with the original backward induction method,the experimental accuracy of the data processed by the error feedback elimination method has been greatly improved.
