Some of the problem-solving techniques developed and used in artificial intelligence, computer science, engineering, mathematics, or medicine are related to mental problem-solving techniques studied in psychology.

or pupil is a learner or someone who attends an educational institution.

In Britain those attending university are termed "students".

In the United States, and more recently also in Britain, the term "student" is applied to both categories.

In its widest use, student is used for anyone who is learning, including mid-career adults who are taking vocational education or returning to university.

When speaking about learning outside an institution, "student" is also used to refer to someone who is learning a topic or who is "a student of" a certain topic or person.

Education is the process of facilitating learning, or the acquisition of knowledge, skills, values, beliefs, and habits.

Educational methods include storytelling, discussion, teaching, training, and directed research.

Education frequently takes place under the guidance of educators, but learners may also educate themselves.

Education can take place in formal or informal settings and any experience that has a formative effect on the way one thinks, feels, or acts may be considered educational.

The methodology of teaching is called pedagogy.
