Final answer:
Your classmate should know that re-using a paper without instructor consent can be both considered cheating and self-plagiarism, which are unethical academic practices.
Step-by-step explanation:
In regards to re-using a paper for a different class without making substantial changes or obtaining instructor permission, there are two important considerations your classmate should be aware of, as per Chapter 5:
- This practice may be considered cheating if it's done to gain an unfair advantage, as it misrepresents the amount of original work done for the course.
- The act of re-using a paper without instructor consent can also be viewed as self-plagiarism, as it involves presenting one's own previously submitted work as if it were new.
To avoid these ethical issues, your classmate should either produce original content or seek approval from the instructor, ensuring proper citation and acknowledgement of any previous work used in the research paper.
