E-learning is technology-based learning, especially Web-based or online delivery of education and training. It has the potential to transform how professional training impacts employers and employees alike. Web-based learning offers particular promise in today's business environment, in which the demand for skilled workers is soaring. Online and Web-based training provides many potential benefits to both companies and employees, including lower delivery costs and minimized productivity losses, just-in-time information, personalized learning, ease of distribution, anywhere and anytime availability, and ability to track progress and performance. Before companies and workers can profit from the promise of online learning, however, the following issues must be considered: quality, learner receptivity, access, and financing. Despite these concerns, Internet-based training is expected to grow dramatically in the next several years. (KC)
