The Libro del Profesor for this level is not merely an answer key; it is a comprehensive pedagogical guide designed to support the teacher before, during, and after class.
1. Detailed Lesson Plans The guide provides a structured breakdown of every unit in the textbook. It suggests sequencing for activities, estimated times for each task, and explicit instructions on how to exploit the material effectively. This is particularly useful for new teachers who are still mastering classroom management at an intermediate-high level.
2. Answer Keys and Transcripts For efficiency, the PDF contains the solutions to all activities found in the student's book and the integrated workbook. It also includes full transcripts of the audio and video materials, allowing the teacher to prepare listening comprehension exercises in advance and anticipate student questions.
3. Photocopiable Materials One of the most valuable sections of the teacher's guide is the bank of photocopiable worksheets. These are extra activities designed to reinforce grammar, vocabulary, and communicative skills. They are excellent for homework assignments or for filling extra time in class when students need more practice on difficult concepts.
4. Assessment and Evaluation The guide typically includes assessment rubrics and tips for evaluating student progress. It helps teachers align their testing with the B2.1 competency goals, ensuring that exams accurately reflect the learning outcomes of the unit.
Use the answer keys to create self-correcting Google Forms. Students complete an exercise from the student book, then scan a QR code you create (pointing to the answer key image from the PDF) for instant feedback.
Q: Is the "Libro del Profesor" the same as the "Cuaderno de Ejercicios"? A: No. The Cuaderno is for students (homework). The Libro del Profesor is your teaching guide. Do not confuse them.
Q: I have the standard "Aula 4" (not Plus). Is the Plus teacher's book compatible? A: No. The "Plus" edition reorganized roughly 30% of the units and changed many audio tracks. Using the old teacher's book with the new student book will cause confusion.
Q: Can I share the PDF with my department colleagues? A: Legally, no. A digital license is typically for one user. However, many schools buy a "Department License" from Difusión directly, which allows 5-10 teachers to access the PDF simultaneously.
Each of the 10 units (e.g., "¿Y tú qué dices?", "Historias para contar") is mapped out. The guide provides:
A: If you legally own the digital license, yes. But 180 pages is costly. Print only photocopiable sections.
Before delving into the teacher’s guide, it is important to understand the context of the XL version. Aula Internacional Plus 4 XL is an expanded edition of the classic B2.1 textbook. It integrates the student's book, the exercise book, and a substantial number of additional resources into a single volume. Because of this density, the role of the Libro del Profesor (Teacher's Book) becomes even more critical, as it helps educators navigate the abundance of material available in the student's edition.
The "XL" truly shines here. You will find 20-30 photocopiable masters, including:
