Many students coming into college don’t know how to cite in MLA, APA, and Chicago style. My kids have used all three depending on their professor’s preference and the country in which they studied. Problems arose in group papers where my kid gets stuck redoing someone’s citations and re-verifying their sources because sources were improperly cited. The plagiarism checker comes in handy when identifying someone in my kid’s group lifted almost everything from the web and that section needs to be entirely rewritten and properly cited. I am less than thrilled when my kid is tied to a group paper.
