This article focuses on communities' contributions to a way of learning that seems to be common in many Indigenous communities of the Americas and among people with heritage in such communities: "Learning by Observing and Pitching In" to family and community endeavours (LOPI). We briefly contrast this with community contributions in "Assembly-Line Instruction," a way of learning that is common in Western schooling, to highlight the distinct contributions of community in these two ways of learning. We theoretically situate the two ways of learning, considering communities and individuals as mutually constituting aspects of the process of life, not as separate entities. Then we discuss the contributions of community to the reasons that people participate, how they interact, and the underlying theory of learning and purpose of learning in LOPI. We briefly address the role of community in how people communicate with each other and evaluate learning. To conclude, we consider the prevalence of LOPI both within Indigenous-heritage communities of the Americas and elsewhere, and our hopes for the contribution of describing this way of learning.
