I'm an American English teacher who has been teaching English for over 25 years and living abroad in Madrid, Spain, since 1993. I graduated with a degree in Sociology from Oklahoma State University in 1990 and was certified as an English teacher in 1994.
I assign optional homework for intermediate-proficiency level students. I usually propose a new topic for the following week's class and, for example, recommend Netflix documentaries, articles, etc. based on the topic.
Homework for Elementary and pre-intermediate students is optional, but if you don't do the homework, you probably won't progress very much.
Our first short session will be free-of-charge because I would like to get to know you and your requirements before we start.
