研究目的:

本研究旨在探究麻醉危机管理模拟教学中,训练环境生态效度对学习迁移效果的影响。在Jeffries模拟教学理论框架指导下,通过严格标准化教师因素、学生因素、教学实践及模拟设计其他要素,将“训练环境”作为核心自变量进行操纵。主要目的为:比较在真实手术室环境(高生态效度)与标准模拟中心环境(常规生态效度)中完成相同危机管理模拟训练后,麻醉规培学员在干预结束后1周的非技术技能表现差异,从而检验环境生态效度对技能学习迁移的因果效应,为优化模拟教学资源配置与培训场所选择提供科学依据。  

Objectives of Study:

This study aims to investigate the impact of training environment ecological validity on the transfer of learning in anesthesia crisis management simulation. Guided by the Jeffries Simulation Framework, the "training environment" is manipulated as the core independent variable while standardizing instructor factors, student factors, teaching practices, and other simulation design elements. The primary objective is to compare the non-technical skills performance of anesthesia residents one week after intervention between those trained in a real operating room (high ecological validity) and those trained in a standard simulation center (conventional ecological validity), thereby testing the causal effect of environmental ecological validity on skill transfer. The findings will provide scientific evidence for optimizing simulation resource allocation and training venue selection.
