While completing your online degree or certificate, you’re most likely going to use the Internet for the majority of your research. Just about anybody can post to the Web, so it’s important that you’re critical of the sources you decide to use. Cross-check your information on several different sites in the webosphere before validating.
Also, if the information is taken from a Web site that has no clear professional or scholarly affiliation, check if the information is supported by hyperlinks to the original source or references for the writing. If so, you should click on these links and use those Web sites as a reference rather than the original site.
