Tutor: Seán Murphy

I have been teaching Maths, Physics and Applied Maths to Leaving Cert Honours level for the last twelve years in CBS Ennistymon, Co. Clare. I also teach Junior Cycle Science and Coding. I have a website www.hardsums.ie where I share my teaching resources for these subjects with other teachers/students.

From 2012 – 2015, I worked as a local facilitator for the Project Maths Development Team. This involved giving courses for Maths teachers in the Limerick and Clare Education Centres. In the last two years, I have also worked for various Education Centres giving teacher courses in Leaving Cert Honours Maths and Junior Cycle Coding.

In my role as chairman of the Clare/Limerick branch of the IMTA (Irish Maths Teachers’ Association) over the last 5 years I have organised events such as MathsFest 2018 in Limerick (see www.mathsfest.ie) and TEAM Maths Quizzes for Leaving Cert students. I also maintain the website www.clareimta.ie for sharing resources with maths teachers

I have also previously given Easter Revision Courses for Leaving Cert Honours Maths students in Ennis, Co. Clare, and at Brú na Páirce, Killarney.

Before changing career to teaching in 2003, I worked as an Electronic Engineer for Parthus/Ceva Inc. ( https://www.ceva-dsp.com ) for 7 years.
