大学生高仿真实践学习策略量表的开发及信效度初步评价

Preliminary evaluation on reliability and validity of college students′high fidelity practical learning strategy scale and its development

[目的]开发大学生高仿真实践学习策略量表,对量表信效度进行初步评价。[方法]对某校参与SimMan综合模拟人实践教学的312名护理专业学生进行实测,利用探索性因子分析明确量表的因子结构,对量表效标关联效度、Cronbach′sα系数及折半系数进行分析。[结果]经探索性因子分析后删减2个条目,形成包括信息加工策略、自评策略、情感策略3个公因子的大学生高仿真实践学习策略修订量表(因子累积方差贡献率为59.867%);课堂参与行为、学习风格(除独立学习风格)均与学习策略呈正相关(P<0.05);量表Cronbach′sα系数为0.868,信息加工策略、自评策略、情感策略因子Cronbach′sα系数分别为0.870,0.848,0.457,量表折半系数为0.871。[结论]大学生高仿真实践学习策略量表的信效度均较理想,但对于情感策略因子的内在一致性问题有待在量表使用过程中进一步改进。

Objective： To develop a high fidelity practical learning strategy scale for college students and evaluate its reliability and validity. Methods： A total of 312 nursing students were tested who participated in SimMan synthetic simulator practice teaching in a university.The factor structure of the scale was determined by exploratory factor analysis.The scale′s criterion correlation validity,Cronbach′s a coefficient and split half coefficient were analyzed. Results： Two items were deleted by exploratory factor analysis.The scale was established with three common factors：information processing strategy,self-assessment strategy and affective strategy（cumulative variance contribution rate of factor 59.867%）.Classroom participation behavior and learning style （except independent learning style）were positively correlated to learning policy（ P 〈0.05）.The scale′s Cronbach′s α coefficient was 0.868,and the Cronbach′s α coefficient of information processing strategy,self-evaluation strategy and affective strategy factor were 0.870,0.848 and 0.457 respectively.The scale′s split half coefficient was 0.871. Conclusions： The reliability and validity of college students′ high fidelity practical learning strategy scale is satisfactory,but the internal consistency of the affective strategy factors need to be further improved.
