What many of us do not realize is that knowledge has a half-life. To understand what this means let us presume that a teacher provides students with 90% of the required knowledge on a subject in the course of an academic year. Suppose the students, on an average, internalize 80% of what they learn. But the half-life of knowledge is, according to new research, between six to eighteen months, on an average. In other words, only half of what was initially internalized is recalled after this period. The most powerful tool available to combat the problem of the half-life of knowledge is that of online learning. The growing understanding of the power of online learning as a tool to combat the half-life of knowledge will carry it into the future. And the entry of new technologies and fields of study that are best suited for online learning will expand the size and power of online education in ways that we cannot imagine today.
