Writing the Introduction and Conclusion

Active learning works for this topic because students need to see introductions and conclusions as purposeful moves, not formulaic boxes to fill. When learners analyze real texts, workshop their own openings, and rebuild weak endings, they move from guessing what a teacher wants to understanding how these sections shape meaning for a reader.

Learning Objectives

1. Analyze published research introductions to identify strategies for establishing context, identifying a research gap, and presenting a thesis.
2. Synthesize the main arguments of a research paper into a concluding paragraph that reflects on significance without introducing new evidence.
3. Evaluate the effectiveness of different opening hooks and closing statements in research papers based on established criteria.
4. Create a compelling introduction and a synthesized conclusion for a research paper that adheres to academic conventions.

Introduction Reverse-Engineering

Provide three published introductions from academic essays or long-form journalism on different topics. Students individually annotate each for: the hook or opening move, the contextualizing background, the identification of the problem or gap, and the thesis. In small groups, they compare annotations and discuss whether all four moves were present and equally effective. Groups then draft a one-sentence description of the 'formula' the writer used.

Prepare & details

Design an introduction that effectively establishes context and presents a clear thesis.

Facilitation Tip: For Introduction Reverse-Engineering, provide one strong introduction and one weak one, then ask pairs to label which jobs each sentence fulfills before comparing notes as a class.

Think-Pair-Share: Summary vs. Synthesis

Provide two versions of a conclusion for the same paper: one that lists what each body paragraph said (summary) and one that draws a larger point from the combined evidence and identifies an implication (synthesis). Students individually identify the difference, then discuss with a partner what specific moves the synthesis version made that the summary did not. Whole-class debrief produces a shared definition of synthesis.

Prepare & details

Construct a conclusion that synthesizes main arguments without introducing new information.

Facilitation Tip: During Think-Pair-Share: Summary vs. Synthesis, give each student two one-sentence summaries and two one-sentence syntheses, then have them sort these into categories before discussing how conclusions differ.

Hook Workshop: Openings That Work

Students individually draft three possible opening sentences for their own research paper using three different strategies: a relevant statistic or finding, a specific illustrative scenario, and a direct statement of the problem or question. In small groups, they read each opening aloud and get immediate audience reaction: which created the most compelling reason to keep reading? Students choose one to develop into a full introduction.

Prepare & details

Evaluate different strategies for opening and closing a research paper.

Facilitation Tip: In the Hook Workshop, model three different hook types (question, surprising fact, anecdote), then have students draft three hooks for the same topic before selecting their strongest for peer feedback.

Conclusion Rebuild

Provide a weak conclusion (summary-only, ending abruptly, or introducing new information) and ask students to rewrite it in pairs. The revision must: synthesize the argument in a single sentence, connect the findings to a broader significance, and close without introducing new evidence. Pairs share rewrites and class votes on which best achieves all three goals.

Prepare & details

Design an introduction that effectively establishes context and presents a clear thesis.

Facilitation Tip: During Conclusion Rebuild, give students a paper with a weak conclusion and ask them to rewrite it in two versions: first as a summary, then as a synthesis, so they feel the difference in their own writing.

Teaching This Topic

Teachers should treat introductions and conclusions as rhetorical choices, not templates. Avoid teaching a single ‘right’ way to write them; instead, show students a range of professional models so they learn to adapt strategies to their purpose. Research suggests that students improve most when they revise these sections after drafting the body, not before, because the body often reveals what the paper truly delivers.

What to Expect

Success looks like students who can explain why a specific introduction works or fails, who revise their own openings to match their paper’s scope, and who craft conclusions that show what their argument collectively establishes rather than just repeating it. By the end, students should treat these sections as tools for clarity, not obligatory paragraphs.

Watch Out for These Misconceptions

Common Misconception

During Introduction Reverse-Engineering, students may assume that every introduction must start broad and narrow to the thesis.

What to Teach Instead

During Introduction Reverse-Engineering, provide examples where the thesis appears early, mid-paragraph, or after context, and ask students to mark where the thesis is introduced and how the surrounding sentences support it.

Common Misconception

During Think-Pair-Share: Summary vs. Synthesis, students may believe that conclusions only need to recap arguments.

What to Teach Instead

During Think-Pair-Share: Summary vs. Synthesis, give students a one-paragraph summary and a one-paragraph synthesis of the same argument, then ask them to highlight the differences in purpose, not just wording.

Common Misconception

During Hook Workshop: Openings That Work, students may think a hook must be dramatic or grandiose to be effective.

What to Teach Instead

During Hook Workshop: Openings That Work, provide examples of understated but precise hooks (e.g., a single surprising statistic or a carefully framed question) and have students practice crafting hooks that match their paper’s tone and scope.

Assessment Ideas

Quick Check

After Introduction Reverse-Engineering, provide two different introductions for the same research topic and ask students to identify which introduction better establishes context and presents a clear thesis, explaining their reasoning in 2-3 sentences.

Peer Assessment

During Conclusion Rebuild, have students exchange drafts of their research paper conclusions and answer: Does this conclusion synthesize the main arguments? Does it avoid introducing new information? Provide one specific suggestion for improvement.

Exit Ticket

After Hook Workshop: Openings That Work, ask students to write one sentence that could serve as a hook for a research paper on a given topic, and one sentence that synthesizes a hypothetical argument about that topic.

Extensions & Scaffolding

• Challenge students to rewrite an introduction paragraph in three different styles (problem-focused, question-focused, anecdote-focused) and explain which best fits their paper’s argument.
• For students who struggle, provide sentence stems for each job of an introduction (context, gap, thesis) and ask them to fill in the gaps before drafting their own.
• Deeper exploration: Have students analyze the introductions and conclusions of two peer-reviewed articles in their discipline, noting how each section connects to the paper’s central claim and what new insight it offers the field.

Key Vocabulary

Thesis Statement	A concise sentence, usually at the end of the introduction, that clearly states the main argument or purpose of the research paper.
Context	The background information and relevant details that help the reader understand the significance and scope of the research topic.
Research Gap	An unanswered question or an area of inquiry that has not been fully explored in existing research, which the current paper aims to address.
Synthesis	The process of combining different ideas, evidence, or arguments from the body of the paper to form a coherent and unified conclusion about the main points.
Hook	An engaging opening sentence or phrase in an introduction designed to capture the reader's attention and interest in the topic.
