Workbook with Audio CD: The workbook is designed to deepen and review the material from the course book. The wide range of exercises includes not only grammar, vocabulary, and phrases but also additional contrastive exercises that allow for comparisons with a previously learned foreign language and the mother tongue. Additionally, there are exercises on phonetics and vocabulary, as well as tasks for self-assessment and self-evaluation. The latter aligns with the portfolio concept of the European Reference Framework. A four-page plateau at the end of each module can be used either for self-study or in class. Here, the topics and learning material of the entire module are reviewed again, focusing on skills training and additional cultural information. A project proposal has been designed in terms of both time and content.
