Group learning
澄清了群体学习的概念，提出区分群体学习与其他概念的特征，并构建了一个聚焦于群体层面学习基本过程（共享、存储、检索）的框架，为测量和研究指明新方向。
We clarify the construct of group learning, encouraging new directions for research. Definitions of group learning vary considerably across studies, making it difficult to systematically accumulate evidence. To reconcile disparate approaches, we first present a set of features for distinguishing group learning from other concepts. We then develop a framework for understanding group learning that focuses on learning's basic processes at the group level of analysis: sharing, storage, and retrieval. By doing so, we define the construct space, identify gaps in current treatments of group learning, and illuminate new possibilities for measurement.
