First of all, I'm French so please excuse my grammar.

So, I'm writting a paper on using education to motivate boys to listen more in class. (Using the Silent Way and Content-Based Instruction in Teaching) This is based on the fact that many boys receive low encouragement in school to study or go further in education. I'm looking for Academic sources on the rate of dropouts from boys and academic failures in boys. Not necesserally vs girls, but it might still be relevant.

Thanks in advance!
