Joshua graduated from the National University of Singapore (NUS) with a Degree in Arts and Social Science. Thereafter, he pursued his childhood dream of becoming a Humanities teacher at the National Institute of Education (NIE). After attaining his Post-Graduate Diploma of Education, he had the privilege of teaching at various government schools. To further sharpen his teaching pedagogies, Joshua returned to NIE to achieve his Masters of Education (MEd). Joshua believes that studying Humanities subjects is more about gaining ‘Heart-knowledge’ rather than ‘Head-knowledge’. According to Joshua, the beauty of teaching of Humanities subjects is not only the impartation of ‘Knowledge’ and ‘Skills’, but more signifcantly the inculcation of ‘Values’ that is often lacking in our modern society. Upon leaving the service, Joshua set up his own Humanities education centre which specialises in the teaching of Social Studies, History and Geography.
