Avoiding Plagiarism and Citing Sources

Active learning works for this topic because citation and academic integrity are skills built through practice, not memorization. Students need to repeatedly identify, correct, and discuss citation errors to internalize why proper attribution matters in research writing.

• 3 activities
• 25 min–40 min

Learning Objectives

1. Critique a given text for instances of potential plagiarism, identifying direct quotes, paraphrases, and summaries.
2. Construct accurate citations for three different source types (book, journal article, website) using MLA 9th edition or APA 7th edition guidelines.
3. Compare and contrast the ethical implications of intentional versus accidental plagiarism in academic and professional contexts.
4. Synthesize information from multiple sources into a coherent paragraph, demonstrating proper paraphrasing and attribution techniques.

Case Study Analysis

⏱ 40 min·Small Groups

Workshop: Citation Correction Relay

Give groups a set of intentionally flawed citations -- wrong order, missing elements, incorrect punctuation -- in both MLA and APA. Groups race to identify and correct every error using their style guides. After the relay, the class reviews the corrections together and the teacher highlights the errors that appeared most frequently.

Prepare & details

Explain the ethical implications of plagiarism in academic research.

Facilitation Tip: In the Citation Correction Relay, circulate with a red pen to physically mark corrections on each team’s paper to model the peer-review process.

Setup: Groups at tables with case materials

Think-Pair-Share

⏱ 25 min·Pairs

Think-Pair-Share: Quote, Paraphrase, or Summary?

Present students with three passages from a source and three different research contexts. Individually, students decide which approach (direct quotation, paraphrase, or summary) is most appropriate for each context and explain why. They share with a partner, then the class identifies where disagreements arose and what principle resolves them.

Prepare & details

Differentiate between direct quotation, paraphrase, and summary in academic writing.

Facilitation Tip: During the Quote, Paraphrase, or Summary? activity, require students to label each example with its citation type before discussing, to make the distinctions explicit.

Setup: Standard classroom seating; students turn to a neighbor

Peer Audit: Checking Each Other's Works Cited

Students exchange their current Works Cited or References list with a partner. Using a style guide checklist, each student audits the partner's list for completeness and format. Partners discuss discrepancies and flag entries that need research to complete (e.g., missing publisher information, unclear source type).

Prepare & details

Construct accurate citations using a chosen style guide (e.g., MLA).

Facilitation Tip: For the Peer Audit, provide a checklist of common citation errors to guide students’ feedback and ensure consistency in their evaluations.

Teaching This Topic

Teach this topic by treating citation as a conversation between writers, not a set of rigid rules. Start with clear examples of how ideas flow from one source to another, then practice rebuilding citations to reinforce the connection between originality and attribution. Avoid overwhelming students with every possible rule; instead, focus on the most common errors and why they matter ethically and academically.

What to Expect

By the end of these activities, students should confidently distinguish between quoting, paraphrasing, and summarizing, and apply correct MLA or APA formatting to each. They will also develop the habit of reviewing their own and peers' citations for accuracy and ethical use of sources.

Watch Out for These Misconceptions

Common Misconception

Plagiarism only happens when you copy text word for word.

What to Teach Instead

During the Quote, Paraphrase, or Summary? activity, watch for students who classify unattributed paraphrased ideas as acceptable. Use the activity’s examples to show how paraphrasing without citation still borrows intellectual property, even when the language is original.

Common Misconception

If you put it in your own words, you don't need a citation.

What to Teach Instead

During the Peer Audit activity, watch for students who overlook paraphrased material in their peers’ drafts. Use the peer review checklist to remind them that paraphrase requires citation to indicate the source of the idea, not just the words.

Assessment Ideas

Peer Assessment

After the Peer Audit activity, have students exchange drafts and use a provided checklist to identify and correct citation errors. Collect their annotated drafts to assess their ability to recognize and fix plagiarism in practical contexts.

Quick Check

During the Quote, Paraphrase, or Summary? activity, present students with three passages and ask them to write the correct in-text citation for each, specifying whether it is a direct quote, paraphrase, or summary. Review their responses to gauge their understanding of citation formats.

Discussion Prompt

After discussing the scenario about changing two words in a sentence, facilitate a class conversation about intent and impact. Listen for students’ understanding of why even small changes to borrowed text require citation to maintain academic integrity.

Extensions & Scaffolding

• Challenge early finishers to revise a poorly cited paragraph using three different citation styles (MLA, APA, Chicago) and compare the results.
• Scaffolding: Provide sentence stems for paraphrasing and a side-by-side comparison of an original source and a paraphrased version before students attempt their own.
• Deeper exploration: Ask students to research the history of plagiarism policies in academia and present on how consequences for plagiarism have evolved over time.
