Educational technology is defined by the Association for Educational Communications and Technology as "the study and ethical practice of facilitating learning and improving performance by creating, using, and managing appropriate technological processes and resources".

Learning is the act of acquiring new, or modifying and reinforcing existing, knowledge, behaviors, skills, values, or preferences which may lead to a potential change in synthesizing information, depth of the knowledge, attitude or behavior relative to the type and range of experience.

The ability to learn is possessed by humans, animals, plants and some machines.

Progress over time tends to follow a learning curve.

Learning does not happen all at once, but it builds upon and is shaped by previous knowledge.

To that end, learning may be viewed as a process, rather than a collection of factual and procedural knowledge.

Learning produces changes in the organism and the changes produced are relatively permanent.
