在线学习

By 2006, nearly 3.5 million students were participating in online learning at institutions of higher education in the United States. Many higher education, for-profit institutions, now offer online classes. By contrast, only about half of private, nonprofit schools offer them. The Sloan report, based on a poll of academic leaders, says that students generally appear to be at least as satisfied with their online classes as they are with traditional ones. Private Institutions may become more involved with online presentations as the cost of instituting such a system decreases. Properly trained staff must also be hired to work with students online. These staff members must be able to not only understand the content area, but also be highly trained in the use of the computer and Internet. Online education is rapidly increasing, and online doctoral programs have even developed at leading research universities.

学习的生理学

Thought, in a general sense, is commonly conceived as something arising from the stimulation of neurons in the brain. Current understanding of neurons and the central nervous system implies that the process of learning corresponds to changes in the relationship between certain neurons in the brain. Research is ongoing in this area.

It is generally recognized that memory is more easily retained when multiple parts of the brain are stimulated, such as through combinations of hearing, seeing, smelling, motor skills, touch sense, and logical thinking.

Repeating thoughts and actions is an essential part of learning. Thinking about a specific memory will make it easy to recall. This is the reason why reviews are such an integral part of education. On first performing a task, it is difficult as there is no path from axon to dendrite. After several repetitions a pathway begins to form and the task becomes easier. When the task becomes so easy that you can perform it at any time, the pathway is fully formed. The speed at which a pathway is formed depends on the individual, but is usually localized resulting in talents.
