George worked at a university with one other person from Global Volunteers where they had different groups ranging in size from about 12 to 20. These groups were not part of regularly scheduled classes and George and his partner planned the discussion topic or activity themselves. I would recommend that other North Americans also teach through Global Volunteers if they have the 19 days to spend, and we arrived two days early, which we would strongly recommend. The program started Sunday evening, but we flew in from Hong Kong on Friday morning. That allowed us to get settled, participate in tai chi early Saturday and Sunday mornings, visit the history museum, walk the wall, and find the nearest Internet cafe.
Travel afterwards is extra.
About half the people hadn't taught much before. You do need energy, imagination, and flexibility. On Monday, we spent the morning in orientation, and by afternoon we received our assignments to various different schools. Formal training was really not possible because of very different settings and expectations. Many of our students had five-six years, but mostly in structured lesson plans.
