The era foregrounds social-contextual learning, participation, and workplace-based learning, with communities of practice as a dominant lens for understanding how newcomers move toward expertise within real work contexts. There is a clear shift toward self-directed, problem-centered design and facilitation, alongside rising attention to informal and incidental learning embedded in daily activities. Historical Significance: These developments mark a move away from passive instruction toward autonomous, engaged learning anchored in social interaction and authentic tasks, laying the groundwork for lifelong learning and organizational knowledge cultures; contributions also embed critical reflection and justice-oriented aims within adult education and professional development.
