腹腔镜模拟教学效果评价指标体系的构建和实证研究

A comprehensive indicator system and empirical study for evaluating the teaching effect of laparoscopic simulation training

本研究通过文献调研、专家咨询法、层次分析法、因子分析法构建腹腔镜模拟教学效果评价指标体系,并对构建的指标体系进行实证研究。研究结果发现,腹腔镜模拟教学效果评价指标体系包括A1腹腔镜模拟器评价、A2实验动物操作评价、A3临床实践评价3个一级指标和相应的10个二级指标及23个三级指标。评价指标体系3个维度间的克朗巴赫α系数为0.968,各维度外在信度均大于0.72。实证研究发现:一级指标中A1~A3结果中有经验组得分高于无经验组,差异有统计学意义(P<0.05);二级指标中B1~B10这10个指标评价结果中有经验组得分高于无经验组,差异有统计学意义(P<0.01)。本研究首次成功构建腹腔镜模拟教学效果评价指标体系。该指标体系具有较好的信度和效度,后续实证研究验证了该评价体系的有效性和实用性,可用于指导后续腹腔镜模拟教学评价的进行和优化。

We reviewed and developed an indicator system framework for assessing teaching effect of laparoscopic simulation training through literature research,expert consultation,analytic hierarchy process and factor analysis.We also made an empirical study on the constructed index system.The system included 3 domains(A1:evaluation of laparoscopic simulator;A2:operation evaluation of experimental animals;A3:evaluation of clinical practice),10 second-level indicators and 23 third-level indicators for assessing teaching effect of laparoscopic simulation training.The indicator system framework has good internal consistency(Cronbachα=0.968)and external consistency(>0.72).The empirical study found that:in the results of A1-A3 in the first level indicator,the score of the experienced group was significantly higher than that of the inexperienced group(P<0.05).In the evaluation results of the 10 secondary indicators in the secondary indicators B1-B10,the score of the experienced group was significantly higher than that of the inexperienced group(P<0.01).For the first time,we have established and evaluated a comprehensive evaluation indicator system which is reliable and effective and can be used for further evaluation of teaching effect of laparoscopic simulation training.The following empirical studies have verified the effectiveness and practicability of the evaluation system.
