Competency based learning is rapidly replacing the old model. In competency based learning, the learner persists until the concept or skill is mastered before moving on. Pretests protect against relearning material already mastered. Post-tests certify when it is time to move forward. Software Web browsing programs such as Netscape or Internet Explorer provide support for a new kind of learning.
Web pages provide a series of steps for the journey while suggesting side trips and excursions.
In addition to enjoying a rich menu of choices, learners control the pacing and customize the experience to match skill levels and style preferences. Online learning is emergent. While quite a few software companies are rushing products forward to support the development of online learning for corporations and higher education, K-12 examples are just now appearing. The WebQuest site funded by PacBell provides online resources that show teachers how to construct their own web-rich research units. No need to attend class.
