We lived in Central Asia for 14 years where we were the Founders/Directors of an NGO working with university students, "Greenhouse Club." At our student center we taught many skills but the main thing most everyone wanted to learn was the English language. We taught English at our center, in universities, in remote villages and often ended up teaching impromptu mini-lessons at the bazaar. :)
Not long ago we moved back to America and even though we spent our childhoods here we found adjusting to life as adults very difficult to navigate culturally. Many of the lessons in this course were formed out of our hope that others coming to America for the first time would learn not only necessary vocabulary but gain an understanding of everyday American societal systems.
