Many subjects seem almost made for virtual learning. Literature, for example, is easy to study online. With ample time given to prepare critical responses, message board literature discussions can be even more fulfilling than a traditional 60-minute lecture.

Other subjects, however, are less conducive to the online learning environment. Science experiments and athletic activities, for example, are difficult to carry out through the internet. And, a few states have decided that learning driver's ed online has the potential to be deadly.

According to an Associated Press article, a Minnesota senate committee recently rejected legislation that would allow online driver's training:

"Several states already allow online driver's ed. But owners of traditional driving schools criticized the legislation, saying online courses would give students too much opportunity to skim over important -- even possibly life-saving -- information."
