Traditional experimental way of handling data has big errors and is unstable.To address these problems,an improved inflection-point method is adopted,and the differential function of origin 8.0 software is used in measuring Planck constant in photoelectric effect experiments.The results show that the correlation coefficient of the five measuring points is 0.994 59,and that the errors are dramatically reduced.Moreover,the data processed by using this method are more accurate and effective,making teaching process concrete and vivid.The effects and quality of teaching practices using this approach are,therefore,improved.
