Interdisciplinary work in history education combines teaching materials and approaches from other subjects and integrates these in the learning process. In addition the history classroom may invite pedagogical input from other subjects, for example by inviting a teacher from another subject. Using teaching materials from other subjects extends the definition of what a historical source is. Using such extended types of sources broadens the concept of what history is about. Using historical thinking in dealing with extended types of sources shows students that history is embedded in/ part of all aspects of life, thus inviting them to use historical skills when being engaged in everyday life situations that are not traditionally seen as being part of history education. Pedagogical input from other subjects shows students of history how historical materials are used by other subjects. In this way the pedagogies of other subjects may enhance the quality of history learning, because it adds more perspectives to working with history.
