Online Learning

The benefits of Online Learning are clear. A teacher and a student have access to limitless information and tools. I wonder, however, if there is a point where online learning ceases to be effective, sort of like the Law of Diminishing Returns? The more we utilize something, the less value we derive from it. In a given school day high schoolers have between 6-7 class periods. If all of the teachers utilized Online Learning all of the time would it have the same educational impact as if it was only used every once in awhile. Would it loses its novelty and its effectiveness? I ask myself the same questions when I look at schools and universities that only utilize online learning. Do students who use only online learning and those who use no online learning benefit has much as those who balance the two? My belief is that balance is key in education. We should utilize all tools and methods to form a balance curriculum. We don't want students to feel as if they can't learn without online learning, but we also want them to get what they can from it.
