I am Lebanese by birth but consider Africa as a second home, as I have been living in Lagos since 2004. I have been teaching at the American International School of Lagos (AISL) since 2008, where I teach foreign languages at the high school level. I piloted the first Arabic program at AISL in 2015/16. I am currently teaching French, Arabic, and the IB courses of ab initio French and ab initio Arabic. For the past three years I have been a presenter at our school’s Nigerian International School Conference where I have presented various workshops on teaching foreign languages with a modern approach. In my lessons, I always connect and integrate the diverse cultures of my students, which enrich our learning environment. I often invite guest speakers from the AISL community to share and talk about their expertise. I have learned valuable teaching methods and strategies, and I had the chance to be involved in multiple professional development and workshops opportunities in the US and other parts of the world. My professional interest is to focus on project based learning, and encourage my students to be actively involved in their own learning, by deepening their knowledge through active exploration of authentic and real-world challenges.
