Following his return to Cyprus, Erduran moved onto secondary school teaching at several schools including Nicosia Girls’ School where he taught for almost 20 years. Apart from Primary and Secondary School Teaching, Erduran's career included Director of In-Service Teacher Training and Instructor at
Anadolu Open University campus in Northern Cyprus. He was a visiting teacher at
George Mason University, USA and was one of the founding members of the
Eastern Mediterranean University, the very first university of the Turkish Cypriot community. Following the
Turkish invasion of Cyprus in 1974, he helped establish a new secondary school in
Lapithos and served as its first head-teacher. Throughout his career, Erduran made numerous visits to schools in the United Kingdom, USA and Turkey. Erduran was an effective teacher who made a significant impact not only on the practice and policy of education but also on the intellectual discourse on education in Cyprus. He was a proponent of interdisciplinary and
holistic teaching. In 1954, he said: :"Teachers, above all, are responsible for raising the cultural capital of the societies that they live in. In order to nurture literate and constructive generations, teachers need awareness of not only their subject knowledge but also other subjects to broaden their vision. Academic knowledge is necessary but not sufficient as a strong cultural foundation of youngsters".
Francis Bacon’s essay “Of Studies” best captured Erduran's passion for
pedagogy and English literature: “Studies serve for delight, for ornament, and for ability” influenced his teaching philosophy in differentiating the purposes of education. He believed in everyone's potential to learn, and took it upon himself as a teacher and an administrator to find creative ways of facilitating learning. He had a rare talent for transforming complex ideas into simple, striking and animated narrative. ==Literature and journalism==
