Adaptive Learning Technologies are the Future of Education

Studies have shown that students flourish when they receive one-on-one interaction with an instructor. Unfortunately, as class sizes have multiplied, that direct interaction between student and teacher has become increasingly difficult to achieve. Without that close interaction, it becomes difficult for a teacher to identify which students are struggling and which are excelling on an individual basis. Worse yet, students performing somewhere in the middle may miss out on opportunities to excel because they aren't getting the guidance they require.
It is too much for one teacher to handle on his own, which is why more schools are looking to adaptive technologies to help them teach. Adaptive technology isn't a new concept, and has been around since the 1970s. It was only in more recent years, though, that the technology has become sufficiently advanced and inexpensive to make it a realistic option.
