Table 1 Two lenses to look at dimensions of the blend

Offline (face-to-face) and online (virtual) learning environments

Spaces (face-to-face, online, autonomous) and time (synchronous, asynchronous) for student-teacher-content interaction

Self-paced (learned controlled) and live, collaborative learning (among many learners)

Pedagogy (conventional, inverted) and locus of control (teacher, students, group)

Structured (formal) and unstructured (informal) learning

Media to attain knowledge (expository, active, interactive media)

Custom content (adaptive, flexible) and off-the-shelf content (generic)

Learning experiences (formal, non-formal, informal)

Learning (before a new job-task), practice (using job-tasks or simulation models), and performance support (Just-in-time coaching)

Learning environments (personal / networked, at work / at home, virtual classroom / physical classroom)
