If you are learning Spanish you could find a reference book to guide you in the process very helpful; a book full of clearly explained language lessons, with many examples and exercises, but how to find the right one?
During my years as a Spanish teacher I worked with a lot of textbooks. But the one that I used the most was Aula Internacional.
Aula Internacional 1 is a textbook which follows the Common European Framework of Reference for Languages (CEFR). This means that all the topics are following a syllabus approved by big institutions. It also means that you’ll find all kinds of activities to train all your Spanish skills: writing, reading, speaking and listening.
But as with many textbooks, Aula Internacional is meant to be taught or guided by a teacher. In fact, all the text is in Spanish. So if you want to use it as a self-taught and don’t know a little bit of Spanish it may be hard for you to begin.
This is why I recommend to use materials from Difusión, a Spanish publishing house specialized in textbooks and materials for students of Spanish as a foreign language. All of them are digitally enabled, provide full mobility, and are also available in traditional print format.
