Reading is a BIG component of teaching any language – first or second. Reading, especially in a foreign language, can be quite difficult for learners. I have been working on earning my TESOL certificate through the American TESOL Institute (ATI). One of the modules I had to complete was about teaching reading.
Reading can be especially difficult since not every student reads at the same level. Some are able to read at higher levels than their peers, and others may struggle.
