Longer essays may also contain an introductory page that defines words and phrases of the essay's topic. Most academic institutions require that all substantial facts, quotations, and other porting material in an essay be referenced in a bibliography or works cited page at the end of the text. This scholarly convention helps others (whether teachers or fellow scholars) to understand the basis of facts and quotations the author uses to support the essay's argument and helps readers evaluate to what extent the argument is supported by evidence, and to evaluate the quality of that evidence. The academic essay tests the student's ability to present their thoughts in an organized way and is designed to test their intellectual capabilities.
Traditional education represents in itself more or less stable structure, without undergoing dramatic differences in the course of years. The accumulation of knowledge goes on, of course, but only in the subjects where it is impossible to avoid, for example, history and literature, which are being expanded all the time. Curriculum for exact sciences, like physics or mathematics may not change for decades. Botkin offers another decision, which presupposes that educational system is dynamic, ever-changing structure that is being regrouped and renewed constantly, with new programs and educational disciplines appearing all the time.
