Paul Dummett is a teacher and writer based in Oxford, UK, where he ran his own school teaching English to professionals from 1996 to 2006. He currently teaches refugee children in Palestine and Jordan with The Hands Up project. His main interests are the use of images and narrative in language teaching and how these can aid deeper learning and memory. Seeking out writing projects that explore these interests he has found a natural home at National Geographic Learning, co-authoring titles such as Life and Keynote and acting as a Course Consultant for Look, a seven-level primary series. He enjoys travel, exercise and live music/spoken word performance. Helen Stephenson first taught business English in the 1980s. She has written in-house training courses and a course for upper-secondary students. She teaches at the Universitat Oberta de Catalunya. Lewis got his first taste of teaching English in Barcelona in the late 1980s. The experience inspired him to get a Master's in TESOL, after which he taught at a university language centre in Arizona and then a manufacturing company in Japan. In 1995, he took an editorial job with a major publisher in Hong Kong developing materials for Asia, and in 1997 became a freelance editor, project manager and writer in the UK. He has worked on books, videos, tests, audio materials, worksheets, apps and online materials for English learners of all ages across the world. He currently lives in York.
