Experimental study shows increased cognition in clients exposed to water quality publications, highlighting their educational value.
Extension, like other educational organizations, uses publications to teach clients, especially when personal contact isn't possible. How much do people learn from these publications? This experimental study looked at two Extension publications on water quality and their effect on cognition of Extension clients in Scioto County, Ohio. Cognition was defined using the Newcomb-Trefz model. Clients who read the publications showed greater cognition overall and higher levels of cognition when asked about the subject matter than those who did not read the publications.
