There is an Education assignment in progress at present where students need to find a single-subject design research article. The academic has given a list of some single-subject design journals. See the list below. Students will generally not have any success using “single subject design” as a search phrase. The journals are all in the Education Research Complete (ERC) database. If they use ERC, they can search for their topic and limit the results to one or more of these journals.

eg: first box:Education and Treatment of Children (change Select a Field to be SO Publication name)
second box: their topic . I tried autism and got 41 articles.

Students will still need to trawl through the results to see if the articles are acceptable. They need to check that they have results that list each subjects results individually. So, more than 1 person can be in the study…they just need to have results displayed separately for each individual.
