What is Knowledge Obsolescence

This chapter explores first the evolution of adult learning primarily in a Western context and particularly in terms of career and technical education. The discussion includes not only lifelong and self-directedlearning, but also the various contexts and venues in which career and technical education occurs. The chapter concludes with both the challenge and promise of e-learning in the field of adult and continuing education, asking what the impact of e-learning specifically may be for learners, stake-holders, instructors, and the field itself.
