Professor John Coolahan was a central figure in educational reform in Ireland and his work has profoundly reshaped the educational landscape across the last four decades. Entitled ‘Pushing Boundaries, Expanding Vistas/: Celebrating the Work of John Coolahan’, this edited book comprises the proceedings of a colloquium held in Maynooth University in October 2017. At this colloquium, a range of contributors provided inputs on the multifaceted ways in which John Coolahan has contributed to education. Each contributor to the book focuses on a distinct aspect of John’s contribution to education, including his role as an educator, a policy maker, an historian of education, a champion of the arts in education and as a researcher. Edited by Dr Thomas Walsh and Dr Rose Dolan, chapter contributors include Mr John Bean, Professor Sheelagh Drudy, Ms Catherine Byrne, Professor Marc Depaepe and Ms Niamh Bhreathnach. John contributes the final chapter of the book, reflecting on the key developments in the transformation of the education system in recent decades.
