English learning around the world

This is my field, so I know in theory how eager people are to learn English.  However, my experiences on this trip made it even more vivid.  I saw eager students, from pre-school to middle-age.  I saw bad teachers (being a native-speaker of English may get you hired, but it does not automatically equip you to teach).  I saw great teachers.  I saw all kinds of classes in different locations.  Here are a few samples from the streets of Hanoi.
