Notice that the writer has not only “borrowed” Chase’s material (the results of her research) with no acknowledgment, but has also largely maintained the author’s method of expression and sentence structure. The phrases in red are directly copied from the source or changed only slightly in form.
Even if the student-writer had acknowledged Chase as the source of the content, the language of the passage would be considered plagiarized because no quotation marks indicate the phrases that come directly from Chase. And if quotation marks did appear around all these phrases, this paragraph would be so cluttered that it would be unreadable.
