This guide has been developed by a working group of the Network for In-tercultural Learningin Europe (NILE)2. The network intends to address the challenges of intercultural learningacross Europe and this guide aims to supportpractitionerswho are contributing to the development of this approach to learning. In the field of adult education and lifelong learning a common feature of learning groups is diversity. Although diversity is always visible in any teaching or learning situation because individuals have different learning styles, preferences and varied life experience, it must also be acknowledged that in many European countries constant migration and mobility have also brought an additional cultural dimension to the situation the teacher or fa-cilitator faces. Although this diversity is not always obvious, factors such as different value systems affecting for example, how men and women relate to each other or how the role of the teacher is perceived can have a major influence on the learning process and outcomes.
