The aim of this study was to develop and validate a scale to measure nursing students’ readiness for the flipped classroom in Sri Lanka.
A literature review provided the theoretical framework for developing the Nursing Students’ Readiness for Flipped Classroom (NSR-FC) questionnaire. Five content experts evaluated the NSR-FC, and content validity indices (CVI) were calculated. Cross-sectional surveys among 355 undergraduate nursing students from 3 state universities in Sri Lanka were carried out to assess the psychometric properties of the NSR-FC. Principal component analysis (PCA, n=265), internal consistency (using the Cronbach α coefficient, n=265), and confirmatory factor analysis (CFA, n=90) were done to test construct validity and reliability.
Thirty-seven items were included in the NSR-FC for content validation, resulting in an average scale CVI of 0.94. Two items received item level CVI of less than 0.78. The factor structures of the 35 items were explored through PCA with orthogonal factor rotation, culminating in the identification of 5 factors. These factors were classified as technological readiness, environmental readiness, personal readiness, pedagogical readiness, and interpersonal readiness. The NSR-FC also showed an overall acceptable level of internal consistency (Cronbach α=0.9). CFA verified a 4-factor model (excluding the interpersonal readiness factor) and 20 items that achieved acceptable fit (standardized root mean square residual=0.08, root mean square error of approximation=0.08, comparative fit index=0.87, and χ2/degrees of freedom=1.57).
The NSR-FC, as a 4-factor model, is an acceptable measurement scale for assessing nursing students’ readiness for the flipped classroom in terms of its construct validity and reliability.
本研究旨在开发和验证一种用于评估斯里兰卡护理学生翻转课堂准备程度的量表。
文献回顾为开发护理学生翻转课堂准备程度(NSR-FC)问卷提供了理论框架。五位内容专家对 NSR-FC 进行了评估,并计算了内容效度指数(CVI)。在斯里兰卡三所国立大学的 355 名本科护理学生中进行了横断面调查,以评估 NSR-FC 的心理测量特性。采用主成分分析(PCA,n=265)、内部一致性(使用 Cronbach α 系数,n=265)和验证性因子分析(CFA,n=90)来检验结构效度和信度。
37 项内容纳入 NSR-FC 进行内容验证,平均量表 CVI 为 0.94。两项条目得分低于 0.78。通过正交因子旋转的 PCA 探索了 35 项条目的因子结构,最终确定了 5 个因子。这些因子分为技术准备、环境准备、个人准备、教学准备和人际准备。NSR-FC 还表现出可接受的总体内部一致性(Cronbach α=0.9)。CFA 验证了一个 4 因素模型(不包括人际准备因素)和 20 项具有可接受拟合度的条目(标准化均方根残差=0.08,近似均方根误差=0.08,比较拟合指数=0.87,χ2/自由度=1.57)。
NSR-FC 作为一个 4 因素模型,在结构效度和信度方面是评估护理学生翻转课堂准备程度的一个可接受的测量量表。
