A preliminary study examined how collaboration could be successfully incorporated as an instructional strategy in a class of adult learners. The study was conducted in a graduate-level class on technology for teachers. The class was composed of 10 current and preservice teachers. The principal content of the class was how to select, design, and use instructional technology in the elementary and secondary classroom. The use of collaboration was considered technologically competent, and training the class in collaboration was the objective. Examining how the class reacted to collaboration with regard to the model of dissemination of innovation by Everett Rogers resulted in the development of a checklist of ways to structure a conversation with learners so that concerns about the innovation of collaboration can be addressed. Checklist items are: (1) relative advantage; (2) observability; (3) compatibility; (4) complexity; and (5) trialability (i.e., can it be tried on a limited basis first). One figure illustrates the discussion. (Contains 21 references.) (SLD)
