课堂环境和气候本质上是课堂水平（L2）的结构，但应用研究人员有时不恰当地代表他们的学生水平（L1）的反应，在单级模型，而不是更合适的多层次模型。在这里，我们专注于重要的概念问题（气候和上下文变量之间的区别;使用课堂L2，而不是学生水平的L1措施）和更合适的多层次模型。为了说明这些问题，我们考虑了两个L2课堂气氛变量和一个L2课堂环境变量对两个L1学生水平的结果为2261名学生在128个班级的影响。通过这个例子，我们说明了如何应用进化的双潜在多水平模型来（a）评估基于课堂气氛和背景测量的多个指标的L1和L2结构的因素结构，（B）控制L1和L2的测量误差，（c）L1反应汇总形成L2结构的控制抽样误差（学生水平的平均反应，形成课堂水平的结构），（d）提供指导方针，适当的分析课堂气氛作为一个第二语言的结构。[可提供本条的补充材料。请访问出版商的《教育心理学家》在线版，获取以下免费补充资源：当前调查的实质性基础以及方法的更详细描述。]
Classroom context and climate are inherently classroom-level (L2) constructs, but applied researchers sometimes-inappropriately-represent them by student-level (L1) responses in single-level models rather than more appropriate multilevel models. Here we focus on important conceptual issues (distinctions between climate and contextual variables; use of classroom L2 rather than student-level L1 measures) and more appropriate multilevel models. To illustrate these issues, we consider the effects of two L2 classroom climate variables and one L2 classroom contextual variable on two L1 student-level outcomes for 2261 students in 128 classes. Through this example, we illustrate how to apply evolving doubly latent multilevel models to (a) evaluate the factor structure of L1 and L2 constructs based on multiple indicators of classroom climate and context measures, (b) control measurement error at L1 and L2, (c) control sampling error in the aggregation of L1 responses to form L2 constructs (the average of student-level responses to form classroom-level constructs), and (d) provide guidelines for appropriate analysis of classroom climate as an L2 construct.
