Teaching large classes is a challenge,I face this challenge everyday as a teacher in a public secondary school.It’s hard for me to move around the class the way I wish .It’s hard to get my students to work in groups or switch places not to mention getting every student to share. Unfortunately, most courses and imported foreign educational strategies do not address this issue.Last year, I attended a very interesting workshop about this topic in the British council,I’ve learned some ideas ,but I still feel I need to learn more ,I ‘m inviting everybody to share their experience and ideas.
