You might read all of the reviews describing this course as intense and roll your eyes, thinking "yeah, right!", but it truly is. This is not a holiday - you will see approximately 0% of Prague most days as you tread wearily back to the Villa after classes, tired and grammared* to death. That said, it's also an incredibly rewarding experience that equips you well for the long journey ahead as a qualified teacher.
The four-week course covers various aspects of teaching theory and practice, with you thrown into a classroom on the second day with real-life students and nary else but your wits...there's an excellent support system provided by the trainers, though, and a library of resources to help you to plan and prepare. You'll prepare detailed lesson plans, assignments on grammar, language analysis, one-on-one tutoring and reflective learning. You'll pick up some survival Czech, get to grips with a young learners' lesson (What do we do? What do we do? What do we do in the moooooorrrrrnnnning?) and make friends for life. Afterwards, you might stay in Prague or you might go elsewhere. But whatever you choose, you'll feel ready and eager to teach. You can't learn everything there is to know in a month, and so in many ways this is only the beginning - but it's a great place to start. It's a challenging, frustrating, motivating course that will help to shape you into a worthy EFL teacher, I promise.
* please don't try to grammar the students to death, they're lovely.
