The Collaborative Learning in Teacher Training (COLTT) project attempted to address a lack of familiarity with information and communication technology (ICT) while providing much needed training for adult education professionals. The project focussed on the use of new communication technology in education. Unfortunately, the use of information and communication technology is not very common in adult education. Although web-based platforms could provide extensive innovations and improvements, they are rarely used even in collaborative learning environments. The Collaborative Learning in Teacher Training project began developing a training programme for lecturers to support their teaching methods with information and communication technology-based tools. The project also produced a handbook on how to integrate information and communication technology learning into the classroom, as well as an electronic logbook for recording class discussions and results. The courses are designed to present a clear defi nition of collaborative learning. They increase familiarity with internet-based platforms, such as how to set up e-mail conferences and use e-logbooks, while providing training on the use of already existing course materials. The whole course is built around the SIMULAB concept for internet-based communication between language students. The course includes preparatory and follow-up phases and targets adult-education teachers and trainers. After the course, participants will be able to increase their familiarity with online-based collaborative learning and initiate both national and international activities for their students. This approach to teaching is fully developed and provides an innovative contribution to the development and modernisation of European adult education.
