Sarah obtained her PGCE in Mathematics from King’s College London in 1997. Her first post was at Elizabeth College in Guernsey as a teacher of Mathematics and ICT. Over the years she gradually moved from the full time teaching of Mathematics to ICT and since 2014 to Computer Science. Her first post as Director of ICT was at St Michael’s Grammar School in Finchley, North London and since then she has held various posts as Head of Computer Science including at Ellesmere College from 2016 to 2022. Sarah has a real passion for teaching algorithmic thinking, programming and artificial intelligence. Algorithmic thinking is a style of thinking which allows the learner to think about performing a task as a computer would. It is a crucial skill which she enjoys teaching particularly to younger children.
