We are getting a bit off-topic (which is not necessarily bad), but I wanted to follow up on Woravut's comments:

It certainly makes sense from the teacher's perspective that large class sizes have a negative effect. The was a study published in 2012 entitled "The effects of class size on English learning at a Thai university" which found that class size does indeed have a negative correlation with student grades -- the larger the class, the worse the grades. As the paper points out, grades don't necessarily mean learning, but it's at least something to back up your ideas. If anyone is interested in reading more, the paper can be found at

This is a great point as well. A study on English learners in Hong Kong in 2012 found that "Students reported that smaller classes promoted a strong sense of security within their classroom community and seemed to weaken students’ fears of negative evaluation from their peers and teachers. Students also reported that they felt more confident about participating in English lessons and these perspectives were supported by evidence from classroom observations."
