David Paterson
David is assistant head and a teacher of chemistry/physics at Aldenham School, Elstree.
David has a particular interest in the use and improvement of practical work in effective science teaching, assessment, and in teacher training and development. He is a fellow of the Royal Society of Chemistry and was awarded the RSC Schools Education Award in 2020.
During his teaching career, David has been head of chemistry, physics and science at state comprehensive schools in Hertfordshire. He was chemistry subject advisor at the UK exam board OCR before returning to the classroom in 2017. He works closely with CLEAPSS, developing practical guidance and training for science teachers across the UK.
