Scenario writing is a method to promote creative thinking and a proactive approach to dealing with the future. ATEE's Research and Development Centre "Curricula in Teacher Education" has adapted this method for use in teacher education. A Comenius funded course on Scenario writing was run over five days with teachers, teacher--educators, and persons in training management from several European countries. The paper reports the results of the summative evaluation which proves the course was very successful. In addition, on the basis of the formative evaluation indications, a detailed analysis makes clear which cognitive, motivational, and social problems are fundamental to courses like this and how these difficulties are to be dealt with.
