【摘要】：网络媒介素养是数字社会中公民的一项基本技能。此次研究研制反映青少年网络媒介素养水平的量表(NMLST),并应用非参数项目反应理论(NIRT)进行校正。采纳国内28省市1408例青少年样本,采用Mokken量度对项目进行分析修正,双因子结构方程模型进行因子验证。研究结果发现该量表符合单维性与单调性检验,可以根据项目反应理论进行修订。最终形成25题项青少年网络媒介素养的测评量表(NMLST-25),各题项参数具有合理的取值范围。结构方程等显示量表具有清晰的因子结构。NMLST-25的题项排序具有不变性特点,经测试后6题项构成核心题干。NMLST-25具备合适的信效度与内部结构,可提供作为青少年网络媒介素养教育的评估工具。
[Abstract]:Network media literacy is a basic skill of citizens in digital society. In this study, a scale reflecting teenagers' media literacy level was developed and corrected using non-parametric item response theory (NIRTT). 1408 samples of adolescents from 28 provinces and cities in China were used to analyze and revise the items by using Mokken measure, and the double-factor structural equation model was used to verify the factors. The results showed that the scale was consistent with the test of single dimension and monotonicity, and could be revised according to item response theory. Finally, NMLST-25 was formed, and the parameters of each item have a reasonable value range. The structural equation showed that the item ranking of NMLST-25 was invariant. After the test, the six items constituted the core question stem. NMLST-25 had the appropriate reliability and internal structure. It can be used as an evaluation tool for youth media literacy education.
