I offer you Spanish classes with an Argentinian native from Rosario. My classes are focused on learning speaking abilities, such us pronunciation and using proper Spanish expressions; and also on reading in order to gain vocabulary. We start with a text (if you already have knowledge), we read it, analyse it and learn new words and grammar. Then, we talk about it to practise speaking. If you are a new student with start with a little grammar to set the basic knowledge and continue little by little with small sentences.
The key is to be patient with the student and have a entertaining class.
