What is essential for the teacher to instruct students about citing sources?

The correct choice emphasizes the importance of teaching students to use quotations effectively and document their sources properly. This skill is crucial in academic writing as it allows students to support their ideas with evidence while also giving credit to the original authors. By learning how to quote and cite sources accurately, students develop their writing skills, enhance their credibility, and understand the importance of intellectual property. This instruction fosters a sense of academic integrity and helps students to build a foundation for conducting research and engaging in scholarly discussions.

On the contrary, memorizing source titles lacks practical application in writing and fails to teach students how to integrate sources into their work. Listing authors without any context does not provide the necessary information for readers to find the sources, rendering the citations ineffective. Discouraging the use of sources altogether would prevent students from engaging with existing literature, thus hindering their critical thinking and analytical abilities.
