“I have a better understanding of how students learn and feel much better prepared now to teach English in the United States“
“I was very pleased with the whole experience. The grammar and phonology modules were great in-depth reviews. The methodology module was an excellent step-by-step guide of how to plan a lesson. I have a better understanding of how students learn and feel much better prepared now to teach English in the United States.
