This is basically the idea behind the present-day Internet, where information is stored and accessed through direct association of content. Yet Bush proposed his ideas in 1945, years before the Internet. Englebart saw the relevance and possibilities in Bush's concepts and coupled that with his own belief that people needed a way to access information for use in solving problems. The result was the development of the first hypermedia system. Motivation to learn is the main difference between education and training.
Education is about delayed rewards and application.
Training is immediate application to solve problems. Our learners are self-motivated to mainly satisfy themselves. We try to appeal to different levels of motivation. Some people want an overview and others want to jump right into the lesson. We provide a mix of parallel paths that can be used linearly.
