What techniques would you use to be sure that a student understands the material?

I am a U.S.F Graduate from The World Language Education department. I loved the learning process…. I am fascinated with language learning. I speak a few and am planning to learn more. I am currently an interpreter and had been for years a translator, a teacher and administrator... I have been in many countries and that opened my mind and widened my exposure to not only different languages but also to a variety of cultures…. I am teaching Arabic and French. France is often considered the language of culture. A French lesson is a cultural journey into the worlds of fashion, gastronomy, the arts, architecture and science. Learning French also offers access to the works of great French writers such as Victor Hugo or Marcel Proust, and famous poets like Charles Baudelaire or Jacques Prévert, in the original text. It means being able to hear the voices of actors Alain Delon or Juliette Binoche, and the pleasure of being able to understand the words of French songs sung by an Édith Piaf or a Charles Aznavour, and even sing them yourself. Arabic is a beautiful language whether you are a student needing help with school assignments or a fan wanting an exceptional journey that starts by learning how to write from right to left. I promise to be there for you and walk the journey with you as a native, a teacher and a lover of teaching what I know best.
