There is no single accepted definition of learning, since it depends on one's point of view or a learning paradigm. Most commonly accepted learning paradigms suggest learning is:

• a visible change in one's behavior which can be measured¹⁾
• the active process of acquisition (including insight, information processing, memory, perception) of new knowledge and developing adequate mental constructions²⁾
• a natural desire of human beings, a mean of self-actualization and developing personal potentials³⁾
• an active, socially enhanced process of knowledge construction based on one's own subjective interpretation of the objective reality⁴⁾
• the process of connecting to information sources containing actionable knowledge and maintaining those connections⁵⁾

Some other definitions of learning we found useful are listed here:

• “acquiring new or modifying existing knowledge, behaviors, skills, values, or preferences and may involve synthesizing different types of information.”⁶⁾
• “the activity or process of gaining knowledge or skill by studying, practicing, being taught, or experiencing something: the activity of someone who learns.”⁷⁾
• “all relatively permanent changes in potential for behavior that result from experience but are not due to fatigue, maturation, drugs, injury, or disease.”⁸⁾
• “a relatively permanent change in mental associations due to experience.” ⁹⁾
