Learners
The intended audience includes students (western) aged 14 or above. The source materials (not the web links themselves) may have to be modified to include the books in your curriculum, but the concepts, language and supporting websites are appropriate for this age group.
This course might be used with either ESL/EFL students or native English speakers. If you choose to use this with EFL/ESL students, take time to read through the site and linked sites to insure that your students' English level is competent to digest the information contained and to prepare yourself to help them understand those portions which will inevitably present difficulty.
