My name is Eva, and I am a qualified Spanish and English teacher. I was born in Madrid, a lively and friendly city that I highly recommend you visiting.
As a teacher, I am sure that the best method to learn a language, apart from that of getting immersed in the native speaking country and its culture, is the one based on the communicative approach which enables the learner to acquire the necessary oral and listening skills to establish an efficient communication. Besides, implementing a task-based learning approach will not only help you to develop the skills mentioned but also the necessary ones for writing and reading in the target language. Nevertheless, the methodology to be used during your lessons will always be designed according to your goals, needs and likings: (conversation, real-life situations or grammar-focused lessons).
For those who are scared of grammar, I have good news since we will tackle it through the cognitive approach. So forget about the endless lists of exceptions and uses.
