Teaching a language, and in particular teaching a language as a foreign language, depends on how we perceive the language itself. As Professor Douglas Brown says in his book "Principles of language teaching and learning", "there are no recipes. There isn't a guaranteed and easy method to reassure success. Every apprentice is unique. Each teacher is unique. And every relationship between teacher and trainee is unique". This means that teaching a language as a foreign language, as well as the teaching process in general, is a constant effort to achieve the best result possible using the appropriate means and methods. "Teaching / Learning Foreign Language," according to Evangelia Kaga, "is not a process of transmitting and mechanistically engaging knowledge, but a synthesis of methodological approaches and pedagogical practices, so that the students acquire the motivation to learn and use language as a means of communication and access to new knowledge and information".
