    Coding lessons at the British International School of Boston

Karen McWilliam


IBDP Coordinator and English Teacher

Throughout my career, I have had the pleasure of teaching in outstanding IB accredited schools, both in the UK and internationally. I have been teaching for almost a decade now, and in that time I have expanded my love of English to include complementary subjects such as Drama, Media Studies, Film, and Theory of Knowledge. After completing my Bachelor of Arts in American Studies at the University of Birmingham, I worked in London for several years in a sales role before returning to university in Canterbury to complete my PGCE in Secondary English. I taught at a mixed-gender, selective state school called Dane Court in Broadstairs for the first four years of my career and then moved to Shanghai to begin teaching at Dulwich College Shanghai for the next four. My role as IBDP Coordinator and English teacher at the British International School of Boston is extremely rewarding, both professionally and personally, and our exceptional students are a delight. 

Throughout the years, I have held various roles within the school community, from Deputy Head of Year, to Assistant Head of English, as well as Extended Essay Coordinator. Each of these roles has allowed me to interact with students with a variety of needs and challenges, and helping them to achieve their personal best – a philosophy that continues to inspire my teaching.

Outside for the classroom, I have directed plays and sung in choirs for the school I have taught in. I was an assessor for the Duke of Edinburgh’s International Award which led to me hiking The Great Wall of China and the mountains and gorges of the Yunnan province of China as well as cycling the east coast of Taiwan and across the Tibetan Plateau. I can usually be relied upon to say yes to a challenge – no matter how silly I look doing it! In my free time, I love to explore all manner of things: food, literature, architecture, nature, history… All the things Boston and New England are so famous for!

I am thrilled to be continuing my own IB World School education at BIS Boston! I think international communities provide wonderful opportunities for promoting learning across cultures, sharing different perspectives, and helping students become global citizens. I look forward to continuing my own learning alongside my students and fellow colleagues.
