Which action should a librarian avoid to help prevent plagiarism?

The action that should be avoided to help prevent plagiarism is making a telephone call to each family. While communication with families can be beneficial in many contexts, a one-on-one telephone call to every family may not be the most effective strategy for addressing the issue of plagiarism. It lacks the broad reach and educational impact that other methods offer.

On the other hand, making a classroom presentation on proper citation is a proactive approach that informs students about how to appropriately credit sources, thereby reducing the risk of plagiarism. Providing resources for research equips students with the necessary tools and information to conduct their work ethically. Organizing a workshop on academic integrity fosters a deeper understanding of ethical scholarship and enhances students' awareness of the importance of honesty in academic work. These actions would be far more effective than individual phone calls in creating a culture of integrity and understanding regarding plagiarism among students.
