Criticism

[1] Criticism falls into several overlapping types including "theoretical, practical, impressionistic, affective, prescriptive, or descriptive".

[1] When criticism of this nature is constructive, it can make an individual aware of gaps in their understanding and it can provide distinct routes for improvement.

[3][4][5] Research supports the notion that using feedback and constructive criticism in the learning process is very influential.

[9] Another distinction that is sometimes made is that critique is never personalized nor ad hominem[9] and is presented in a way that encourages rebuttal or expansion of the ideas expressed.

The term originated in the 17th century, derived from the practice of throwing bricks as projectiles at a person who was disapproved of.
