The project "Developing methods of teaching tadelakt and natural building and creating wider opportunities for adults to learn it" focuses on different teaching methods of natural waterproof technique tadelakt and other fields of natural building. This is a popular topic among adult learners, there are many courses about it. But in modern world there is a need of using other methods of teaching than physical courses and therefore during the project we work out an Internet step-by-step guide about tadelakt in English, Estonian, Spanish and Portuguese. It will consist of text with photos and videos and it will be freely available on each partner's webpage. The project has three partners from Estonia, Spain and Portugal. All the partners are active in the field of natural building and in adult learning. During the project the staff of each partner organisation gets new language skills, practical skills, teaching methods and an international experience of cooperation. Those results are achieved with the communication between the partners during the project and especially with the activities during the project meetings: workshops of natural building and tadelakt, exploring the works of other partners, testing teaching methods on each other, etc. This all helps to create the main output of the project - the tadelakt step-by-step guide. This is jointly developed during and between the project meetings, each partner has its part it the development. The Estonian partner integrates also unemployed low-skilled persons to the development process, by testing on them the methods described in the guide. Including unemployed persons in this process has two purposes: making the guide understandable for everyone by testing it on people who do not know anything about tadelakt and meanwhile working out a better work practice programme for re-skilling the unemployed persons. The project has the following objectives: making learning tadelakt more available for adult learners on European level, offering more tailored learning opportunities for unemployed low-skilled persons, partner organisations are more able for international cooperation and carrying out international workshops, higher knowledge about the benefits of natural building, creating healthier and greener environment.
