“A resource or medium (lat.: medium = middle, midpoint) is something that is positioned between two domains. Language, gestures, paper, pencil, books, videos, ruler and compass, computer or interactive whiteboards are media and, in mathematics, they are positioned between mathematical objects (concepts, statements, algorithms) and human thinking, they mediate between mathematics and understanding” (Trgalova et al., 2018, p.143).
The term resource can be referred to a wide range of elements. Adler (2000) assumes a similar broad perspective considering both human, and material and cultural resources.
Educational resources are used in a learning environment to help and assist with people’s development and learning.
