I like to use a method based on communication and cognitive grammar, which consists on teaching grammar through images that helps retain grammar knowledge more easily and avoids confusing and, sometimes, contradictory rules.
I adapt each leeson to each student, so as to carry them on in a comfortable, suitable atmosphere. I'll provide any necessary material for the lesson via e-mail, Google Drive or so, so you can review them before the lesson starts. Grammar and vocabulary are obvious relevant points when it comes to talk about languages, but I also love to include useful expressions, tricktips to get the knack of conversation and cultural notes about Spain and Central-South America. I also like to practice writing, listening, reading and speaking skills in each class, but I focus on improving lacking areas of your proficiency in Spanish.
So, why don't you pick up a lesson and try it out? I'll be waiting for you!
