The What Works and Why project aimed to build digital literacy and engagement for students and teachers in Irish higher education. The basic premise was there is no ‘one-size-fits-all’ approach to the effective use of new digital technologies for teaching and learning. Staff and student digital literacy was enhanced through workshops, seminars, drop-in clinics, small-scale innovation projects, and peer-mentoring groups, which resulted in a collection of guides and resources that shared lessons on what works and why with respect to the digital dimension of teaching and learning.
