entry should be pertinent to the subject matter and demonstrate knowledge and understanding of the topics discussed with an appropriate introduction, supporting paragraphs, and conclusions. You can use Internet articles, journals, textbooks, YouTube, etc. In fact, I strongly recommend that you utilize the UTA (University of Texas at Arlington) Library for your research as they offer a plethora of reliable and pertinent research sources.  There are many online journals and texts available to you there.  However, you should NEVER use Wikipedia for your research as anyone can alter the information on this site making it a poor source of accurate information.  Don’t forget that your posts should be listed in your own words using proper citations when indicated.
