Description

Cultural-historical activity theory (CHAT) holds that human thinking and learning cannot be separated from the culturally mediated activity in which they occur. Building on Vygotsky's insight that action is mediated rather than a direct stimulus-response link, CHAT analyzes learning through activity systems: a subject pursuing an object (a motive) using tools, within a community governed by rules and a division of labor. Object formation is treated as a joint, evolving achievement of participants rather than a fixed target defined in advance — the same activity can shift meaning as different groups (e.g., students, teachers, outside partners) bring different histories and interests to it. Two concepts extend the framework for settings that cross institutional boundaries: a boundary object is something plastic enough to adapt to each group's local needs yet stable enough to hold a shared identity across groups, and dialogicality describes how meaning is made by encounters between old (there-and-then) and new (here-and-now) meanings carried into the activity by different participants.

Expansive learning, and its collective vs. system-level distinction. Fourth-generation CHAT (Engeström) treats expansive learning as the production of "new material objects, practices and patterns of activity" in response to a systemic contradiction — opposing forces materialized in the activity's own practices, not mere individual friction. A double-bind (Bateson; Engeström & Sannino) is a specific, acute form of systemic contradiction in which participants face "pressing, equally incompatible, and unacceptable alternatives" — for example, having to choose between attending a participatory process that feels tokenistic or not participating at all. Meléndez (2021) refines expansive learning into two distinct, separable levels: collective-level learning — qualitative change in a group's agency to engage in a practice (e.g., participants shifting from passive attendance to actively voicing demands) — and system-level learning — change in practices mediated through new artifacts, roles, or activity structures that outlasts and generalizes beyond the original group (e.g., a new committee structure later adopted elsewhere). The key finding motivating this split is that expansive learning can occur at the collective level without ever materializing at the system level — resolving a double-bind durably requires deliberately introducing new mediating artifacts and roles, not just expanding who is present.

Implications

Context

• Most relevant when learning spans multiple activity systems — e.g., school and workplace, classroom and community — rather than occurring inside one self-contained setting
• Useful for analyzing why an intended learning objective can drift once real participants with different motives act on a shared task

Target Learners

• Learners in project-based, community-partnered, or boundary-crossing designs where multiple groups (not just teacher and student) shape what is actually learned

Target Learning Objectives

• Explaining how a "learning object" — the content or skill a design intends learners to construct — can be jointly reconstructed, narrowed, or contested in practice
• Diagnosing tensions between a design's intended conceptual content and the meaning system participants actually adopt

Claims

• Community projects need conceptual framing to avoid narrowing the learning object [~W]
• In one participatory budgeting case, Latino immigrant participation lapsed under outreach with interpretation and was sustained only after the activity structure was redesigned [+M]

• Uneven GenAI access across teams creates a two-speed culture pressuring teams without access despite equally demanding work [~W]
• Encounters with a mismatch between client's and worker's learning cycles typically contained all or almost all learning actions of the ideal-typical expansive cycle [+W] — attached 2026-10-18 from Nummijoki et al. (2018), which proposed "Expansive learning cycle as a framework for analyzing micro-cycles in recurring work encounters".
• In encounters where both client and worker are predominantly defensive, the learning cycle stalls before implementing, reflecting and consolidating actions [~W] — attached 2026-10-18 from Nummijoki et al. (2018), which proposed "Defensive learning cycle: learning to protect routines and avert adoption of novel actions".
• In 30 home care visits implementing the Mobility Agreement, the most common cycle combination was client-expansive and worker-expansive (40%), yet at least one party was predominantly defensive in 60% of cases [~W] — attached 2026-10-18 from Nummijoki et al.

• Digital mapping tools slow down students' judging and categorizing of online material, prompting collaborative negotiation of how to make sense of a controversy [+W] — attached 2026-10-18 from Solli et al.

• Three contradictions emerged in the SimLab process — individualised emergency response, excluded non-clinical staff, and outdated CPR training — and their collaborative resolution drove organisational change [+W] — attached 2026-10-18 from O'Hare et al.

• In a theory-guided in-situ simulation programme, an interprofessional primary care team progressed through the expansive learning cycle from questioning current practice to consolidating new practices [+W] — attached 2026-10-18 from O'Hare et al. (2025), which proposed "Cultural-historical activity theory and expansive learning as a design and analysis framework for interprofessional in-situ simulation".
• The article claims tools should sustain and potentially enhance joint activity beyond the here-and-now and the face-to-face [+W]
• Early realization of a shared object/motive bonds adult course participants into a quasi-community [+W]
• LLMs redistributed educational labor while family and institutional rules left parents and professionals responsible for interpreting outputs and deciding how they entered practice [~W]
• Children's tool use progresses from unspecific manual use to specific instrumental use governed by the tool's culturally established mode of acting [+W]

The evidence by question

• Does introducing a new tool, space or programme change practice on its own, or does lasting change need the activity's rules, roles and community redesigned with it? An innovation foreign to the rest of its system tends to be rejected; lasting change needs a coordinated bundle of innovations. [+M]
• When several groups act on a shared task, does the learning object stay what the design intended, and what keeps it from narrowing? Community projects need conceptual framing to avoid narrowing the learning object [+W]

Related Theories

• Situated Learning — shares the premise that cognition is inseparable from social and material context
• Constructivism — CHAT extends constructivist ideas to joint, historically situated activity rather than individual meaning-making
• Onto-Epistemic Heterogeneity — both frameworks treat participants' distinct histories and ways of knowing as constitutive of what gets learned, not as noise to be normalized away
• Adaptive Cycles Framework — both are systems-level frameworks for change, but adaptive cycles specifically models phase and timing dynamics rather than activity-system structure
• Boundary Crossing Learning — shares CHAT's boundary-object concept but foregrounds the specific dialogical mechanisms (identification, coordination, reflection, transformation) of moving between activity systems
• Cultural-historical Activity Theory and activity-system analysis as a lens for examining PLC in mathematics
• Activity theory: a mediated activity system framework for analyzing cognition in context
• Cultural-historical activity theory (CHAT) as a framework for analyzing community service-learning

Examples

• Community-Based Learning — CHAT explains why community partnerships can produce a different learning object than the one intended if participants' meaning systems are not reconciled
• Use activity-system analysis (objectives, rules, norms, artifacts, division of labour) as a reflection tool for CSL participants
• Format learning activities as play using the three interrelated parameters of involvement, rules, and degrees of freedom
