A classroom, an educational commons, a language model and a body of Indigenous ecological knowledge differ radically in form, yet all demonstrate that cognition is relational. What can be learned depends upon who may contribute, what resources are shared, which distinctions are valued and which infrastructures remain visible enough to be questioned. Educational commons establish the political ground of this relation. Knowledge becomes common not because it is merely accessible but because participants acquire some capacity to shape the process through which it is produced and maintained. Redistribution, recognition and participation define a governance structure for learning. The commons therefore opposes both privatisation and passive consumption by treating educational environments as collective institutions. Thinking infrastructures complicate this picture because participation can occur inside systems whose internal operations remain opaque. GenAI distributes cognition across human and computational actors, but it also introduces valuations that may quietly reorganise what counts as good writing, legitimate knowledge or efficient thought. Infrastructure literacy is therefore not supplementary digital competence. It is the capacity to perceive how technical arrangements participate in the production of judgement. Indigenous Knowledge extends infrastructural learning beyond formal institutions and technological systems. Knowledge may reside in recurrent observation, land relations, collective memory, seasonal practice and intergenerational transmission. Its durability depends on social and ecological continuity. Extracting information while severing those relations can preserve statements while destroying the knowledge infrastructure that gave them meaning. Socioplastics can treat learning as a property of the corpus itself. A field learns when new sources do more than accumulate: they alter relations, expose blind spots, generate new paths and force existing categories to become revisable. Readers, indexes and cross-field essays can create temporary common spaces where different regimes of knowledge meet without being subordinated to a single method. The infrastructure should make its own acts of valuation visible enough to be contested. Infrastructural learning adds a recursive capacity to Socioplastics. The field does not merely store knowledge about infrastructures; its own classifications, interfaces and generative tools become objects of education and revision. Learning occurs when users can understand how routes were produced, how sources were selected and how alternative relations might be constructed. The concept adds an epistemic commons in which knowledge remains productive because the conditions of its production are themselves open to study.
