Stephanie Castle is an IB Biology teacher at the United Nations International School in New York and an IB Assistant Examiner for Biology who has just been nominated as a ‘Teacher of the Future’ for 2013 by the National Association of Independent Schools (NAIS). She has a strong interest in how teachers can effectively use technology in their classrooms to improve learning, increase student interactivity during lessons and facilitate development of deeper understanding in their subjects. To that effect Stephanie has developed the first iTunes U course for IB Biology - www.bit.ly/17CXWUs - and a YouTube website - www.youtube.com/SCsciencevid - to specifically support the course. She entered teaching as a Science teacher through Teach First in the second cohort of the program back in 2004. Stephanie taught in a challenging London secondary school for 3 years, specializing in Biology and coordinating Key Stage 3 Science, before transitioning to the International School system.
