The characteristics of recent research on learning disabilities were examined in a survey of all articles on learning disabilities published in eight major journals during the last three years. The content areas addressed in this research appear to have changed dramatically from research conducted prior to 1970. There continue to be serious problems related to the manner in which learning disabled children are selected for research, and these problems are compounded by the failure of researchers to adequately describe their samples. Although general methodological problems are apparent in the design of much of the research on learning disabilities, a fairly high proportion of studies did employ true experimental designs.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
