The Non-Formal Learning Handbook for Volunteers and Volunteering Organisations is an outcome of the project Volunteers at the Interface between Formal and Non-Formal Education. The main aims of this Erasmus+ Key Action 2 project have been to create synergies between formal and non-formal education, promote the use of non-formal, participatory learning methods in formal educational settings and thereby address the learning needs of children and youth, in particular young people at risk. In doing so, the project has strived also to strengthen the contributions of the large numbers of volunteers engaged in formal education projects worldwide. Spanning 20 months from 1st October 2015 to 31st May 2017, the project has involved ICYE National Committees in 15 countries (Austria, Bolivia, Colombia, Denmark, Finland, Ghana, Iceland, India, Italy, Mexico, Nepal, Poland, Slovakia, South Africa, UK) and 12 formal and non-formal education host organisations, where 14 EVS volunteers learnt, introduced, and experimented with a non-formal learning approach and methodology in the diverse groups they worked with (children in kindergartens, the differently abled, young people with special needs…) for an 8-month duration from 1st April – 30th November 2016. This handbook was developed at the Final Evaluation in La Paz, Bolivia in March 2017 by the taskforce of the above-mentioned project and representatives of two host organisations. It is based on the programmes and methods developed at the multiplier training in Vienna, Austria in February 2016, and the feedback received from the teachers, educators and EVS volunteers in the project. The handbook offers a selection of 40 non-formal learning methods to enhance academic achievement, intercultural learning, physical and emotional development of children and young people. The descriptions of the methods provide a “source”, for which you will often find the name of an EVS volunteer or a host organisation — as these methods were used during the EVS and/or recommended by them. We would therefore like to thank the volunteers and host organisations not only for their invaluable feedback but also for helping us make this handbook a reality. We also extend grateful thanks to Grenzenlos-ICYE Austria and ICYE Bolivia for hosting the international multiplier training and final evaluation respectively. Our sincere thanks goes to the European Commission, which co-funded the project and enabled members of the ICYE Federation to build bridges between the two streams of education. We hope that the handbook can make learning an interactive and collaborative process so that education can contribute more fully in today’s ever-changing world.
