In education, realia (/ r iː ˈ eɪ l ɪ ə /) are objects from real life used in classroom instruction by educators to improve students' learning. [1] A teacher of a foreign language often employs realia to strengthen students' associations between words for common objects and the objects themselves. In many cases, these objects are part of ...
Object lessons were important elements in teaching during the Victorian era of the mid- to late-nineteenth century. [4] Elizabeth Mayo's books Lessons on Objects and Lessons on shells, which were about object lessons and were published during the Victorian Era, were revolutionary as they were the first to explain education to infant teachers.
In mathematics education, a representation is a way of encoding an idea or a relationship, and can be both internal (e.g., mental construct) and external (e.g., graph). Thus multiple representations are ways to symbolize, to describe and to refer to the same mathematical entity. They are used to understand, to develop, and to communicate ...

In mathematics, a representation is a very general relationship that expresses similarities (or equivalences) between mathematical objects or structures.Roughly speaking, a collection Y of mathematical objects may be said to represent another collection X of objects, provided that the properties and relationships existing among the representing objects y i conform, in some consistent way, to ...
Another way to define similarity, best known from geometry, is in terms of transformations. According to this definition, two objects are similar if there exists a certain type of transformation that translates one object into the other object while leaving certain properties essential for similarity intact.
A similar perspective is viewing representation as part of a larger field, as Mitchell, saying, "…representation (in memory, in verbal descriptions, in images) not only 'mediates' our knowledge (of slavery and of many other things), but obstructs, fragments, and negates that knowledge" [8] and proposes a move away from the perspective that ...
