This is a very detailed explanation of plagiarism. I like the outside resources that were used and the New York Times video is a great visual and audio representation of the subject matter.
Because the information covered is extensive and in depth, you might consider entering “check point” questions for the student to make sure they are not getting lost and that they understand each type of plagiarism before moving on. It gives them the opportunity to go back and review concepts before moving on to the next section.
The case studies are great as well. One area that potentially you could add to this section is a highlighting tool of sorts. That way as the student is reading they can mark areas that look like the reason for the plagiarism or even as another visual reference point for them.
