Twenty years of productivity in ETR&;D by institutions and authors

This study was conducted to identify the most productive institutions and the most productive ETR&D authors from 1989 to 2008. Productivity scores were calculated using the number of first, second and third authorships in the journal. Arizona State University had both the highest institutional productivity score and the most authorships overall, while Florida State University had the most first authorships. Michael Hannafin of the University of Georgia ranked first in author productivity score and tied for first with Howard Sullivan of Arizona State for total authorships. David Jonassen of the University of Missouri had the most first authorships. Productivity patterns among top-ranked institutions and top-ranked authors are discussed.
