Using Google Scholar will limit your search of the web to scholarly materials and help you to avoid commercial and unreliable sources. NOTE: when you find abstracts to articles which are not in full text - be sure to search the NNU Library Journal List by the Journal Title to determine whether you might have access to the full text article in one of the library databases or in the print collection.
Search these database tools by your topic to find articles. If an article is not in full text you will be provided with a link to place a request for an interlibrary loan.
Frequently, research on educational topics such as "reading fluency", "disabilities", or "student achievement" can be found in disciplines such as psychology, and social work. I would encourage you to include these in your search to ensure that you have done a thorough literature review.
