In my class, I offer my students a French course with a real French speaker. I also happen to study French teaching at the Hogeschool Utrecht and used to teach to my classmates back in High School. In my class, the students choose wether he/she/they wants to talk (E.G basic conversation to improve their understanding of the frenchspeaking ), study (E.G course+homework+test) or if they just want to have fun while studying (E.G playing french games or watching, listening to french music/films). As a French studying French teaching, I can assure you that you or your kids will be improving in French no matter what.
