Why is the interdisciplinary approach necessary in analyzing the societal issues from the past to the contemporary?

this type of study allows the student to learn by making connections between ideas and concepts across different disciplinary boundaries. Students learning in this way are able to apply the knowledge gained in one discipline to another different discipline as a way to deepen the learning experience. The most effective approach to interdisciplinary study enables students to build their own interdisciplinary pathway by choosing courses which make sense to them. For example, it is not too difficult to find a theme which crosses over disciplinary boundaries in literature, art and history or science and mathematics. Studying topics thematically is one way to bring ideas together resulting in more meaningful learning. This can occur by allowing students to choose their own subjects and their learning is deepened when they reflect on the connections between what they are learning in different disciplines.

One of the biggest barriers to achieving true interdisciplinary study in education environments is the necessity for collaboration of educators. This can be difficult to achieve, but not impossible. Interdisciplinary teaching and learning is maximised when professionals from different disciplines work together to serve a common purpose and to help students make the connections between different disciplines or subject areas. Such interaction is in support of the constructivist paradigm which allows for new knowledge construction and a deeper understanding of ideas than disciplinary study.
