Required reading is an important aspect of teaching literature in the subject of Croatian Language and Literature. Its primary task is to develop and support the student’s motivation and love for reading by providing encounters with valuable literature. Required reading methodology has been unaltered for a long period of time, so there is a need for new and more efficient ideas. Creative approach to required reading is a concept which promotes innovations in literature methodology, with the student’s motivation and curiosity as its starting point. One of its principles is integration – a constructivist approach which advocates meaningful linking of knowledge and skills from different areas across the teaching and learning process. Ideas of integrated approach were established within the constructivist movement, starting at the end of the nineteenth century, and they are still relevant in contemporary educational trends. Integration is a complex organisational form, so the teaching practice may need concrete guidelines for its implementation. Apart from giving an overview of integration theory, its development and characteristics, this paper will try to explore the possibilities for organising integration based on required reading. It considers the integrative potential of literature in the light of diversity of its artistic and informational components, and links it to general terms of organisation and realisation of interdisciplinary teaching. The study will also present a proposal of an integrated teaching unit based on a required reading work for the fourth grade of primary school – Pippi Longstocking by Astrid Lindgren. The main idea of this work is that exploring the integrative possibilities of literature could be an accessible and valuable starting point for making progress in teaching practice.
