I am teaching abroad to non-native English speakers with a large variance of language skills.
I teach both pre-calculus and AP calculus (AB & BC). For both of those classes I define the new terms. I use word problems, have them read from the textbook, take notes in English during class, have the students speak English in class, and teach the class in English.
I am asking this question because my CP told me I need to embed more English into my lesson, so the students learn English.
So what are some techniques to embed English into a mathematics lesson, and what skills and lessons have you learned from teaching mathematics in an ESL environment?
