基于扎根理论的青少年体育与健康素养评价体系构建研究

Establishment of adolescent sports and health literacy evaluation system based on Grounded Theory

目的构建青少年体育与健康素养评价体系,为学校体育与健康素养培育及评价提供科学参考。方法采用扎根理论,借助“Nvivo12.0Plus”软件对研究资料进行三级编码,运用专家咨询法对评价指标进行修正,利用问卷调查数据进行项目分析和探索性因素分析,采用结构方程模型构建评价体系。结果三级编码形成434个自由节点、33个子节点、7个节点;项目分析和探索性因素分析确立由7个维度、27个观测指标构成的评价体系框架;青少年体育与健康素养评价体系模型适配度高,模型拟合理想(GFI=0.923,AGFI=0.904,CFI=0.916,RMSEA=0.051);项目信度(SMC)大于0.25,组成信度(CR)大于0.65,收敛效度(AVE)大于0.36,模型具有良好的信效度。结论编码提取的评价指标较全面,模型具备较高的信效度,适合青少年体育与健康素养评价。

Objective To construct an evaluation system for teenagers'physical education and health literacy,and to provide scientific reference for the cultivation and evaluation of school physical education and health literacy.Methods Based on the grounded theory,the research data were coded in three levels with the help of"Nvivo 12.0 Plus"software,the evaluation index was revised by expert consultation,the project analysis and exploratory factor analysis were carried out by questionnaire data,and the evaluation system was constructed by structural equation model.Results Three-level coding formed 434 free nodes,33 child nodes and 7 nodes.Project analysis and exploratory factor analysis establish an evaluation system framework consisting of 7 dimensions and 27 observation indicators;The evaluation system model of teenagers'sports and health literacy has high adaptability and ideal fitting(GFI=0.923,AGFI=0.904,CFI=0.916,RMSEA=0.051).The item reliability(SMC)is greater than 0.25,the composition reliability(CR)is greater than 0.65,and the convergence validity(AVE)is greater than 0.36,so the model has good reliability and validity.Conclusion The evaluation index extracted from the code is comprehensive,and the model has high reliability and validity,which is suitable for the evaluation of teenagers'sports and health literacy.
