摘要
依照教学目的进行划分,把课堂上的教学互动分为3类:检验互动、启发互动和测试互动。针对其中测试互动类问卷,预留过短的答题时间会影响问卷信度,过长的答题时间又会影响课堂满意度。该文结合近3年的课堂实践数据,以层次分析法和价格敏感测试法为对象,重点分析了327个样本答题时长和一致性系数之间的关系,发现:首先课堂上答题时长和问卷信度并没有正相关性,其次平均答题时长近似服从均值为8.4 s,标准差为3.6的正态分布,最后建议数据分析类课程应开设在低年级学期。
Divided by teaching goals,teaching interaction has three types:verification interaction,enlightenment interaction and test interaction.Aiming at test interaction questionnaire,too short answer time will lower questionnaire reliability,and too long answer time will lower student satisfaction.This paper analyzes the relationship between answer length and consistency coefficient in the past three years from 327 samples,based on Analytic Hierarchy Process and Price Sensitivity Measure.First,there is not positive correlation between class answer length and questionnaire reliability.Second,average answer length nearly obeys a normal distribution with mean 8.4 seconds and standard variance 3.6.Last,data analysis class should open in junior grade.
