I have been working in the Educational Technology field within Higher Education for eleven years. A big part of my job is finding new and innovative ways of integrating technology into current teaching and learning methodology. This can include assisting academic staff with Virtual Learning Environments/Learning Management Systems (Blackboard), implementing specific software packages, maximising current technologies and championing new ones. I find this profession both riveting and rewarding. I really enjoy life on the cutting edge, but I also enjoy being able to help staff achieve small and meaningful efficiencies; sometimes that makes all the difference.
