“AP is my favorite course to teach because it allows me the creativity and flexibility to touch on themes covered in other AP courses in a personalized and meaningful way.  With reference to teaching AP, split-level classes are a reality for me and I am happy to share my resources and tips on how I address the III/IV split.  Additionally, I am a fan of French music and cinema and enjoy sharing my latest interests and how I integrate them into my program.  I like to present with a fully loaded website of materials that I encourage teachers to use in order to create a thematic unit while at the summer institute.”
