The document discusses several frameworks for conceptualizing mobile learning, including:
1. Koole's FRAME model which considers the overlap between the learner, social, and device aspects of mobile learning.
2. Activity theory which views learning as situated within a social context and influenced by mediating tools/artifacts. Mobile devices can expand the tools available for learning activities.
3. The sociocultural theory of learning which emphasizes that learning occurs through communication and collaboration between learners, teachers, and experts. Mobile devices can facilitate these interactions.
The document analyzes how these frameworks apply to different contexts of mobile learning like museums, field studies, and problem-based learning.
