This paper describes a study in which one specific form of follow-up, the action plan, was used to assess the effectiveness of a teachers' course with 15 German teachers of English and offers an evaluation of the plan's potential as a program evaluation instrument. The course was taught for 20, 1.5 hour sessions, in the mornings; afternoons were composed of a self-directed project, optional lectures, and local educational site visits. The action plan was introduced to participants on the last day of the course, with the objective that in 2-3 months, they would be asked to report on their progress toward the objectives they had formulated for the action plan. After 3 follow-up letters/postcards to all 15 students, 11 responses total, had been received. Analysis and comparison of action plans and responses revealed that action plans do seem to offer a feasible and economical way of gathering information that is of value to course organizers, especially regarding input to course design. The most difficult thing for the teachers was to find the time to adapt materials or to think through a different way of doing things. The action plans proved to be useful instruments for both evaluation and awareness-raising. (NAV)
