Quiz — Chapter 16: Theses and Dissertations

Target: 70%+ before moving on. Answers are hidden — attempt each before expanding.


Section 1 — Multiple Choice

1. Which best captures how a thesis differs from a research paper?

A. A thesis is simply longer than a paper. B. A thesis answers a whole question and must make an explicit original contribution, where a paper reports one result. C. A thesis uses IMRaD and a paper does not. D. A thesis is written for a general audience.

Answer **B.** The three real differences are scope (a thesis answers a question; a paper reports a result), depth (a thesis shows and justifies its scaffolding), and original contribution (stated in one sentence). A is the surface symptom, not the cause — length is a *consequence* of the three differences. C is backwards: papers commonly use IMRaD; a thesis builds its own structure. D is false. See §16.1.

2. "This dissertation explores the role of automation in supply chains." The main problem is that it is:

A. Too narrow to fill a dissertation. B. A topic, not a claim — it cannot be wrong, defended, or known to be finished. C. Written in passive voice. D. Missing citations.

Answer **B.** "Explores the role of" describes a topic. A thesis statement is a *claim* — an assertion that could be wrong and that the work will defend ("this dissertation shows that X, under conditions Y, achieves Z"). You cannot disagree with a topic or know when it is done. See §16.1–16.2.

3. The proposal is best understood as:

A. A formality you must complete before real work. B. A contract: committee approval means the agreed work, done reasonably, constitutes a thesis. C. A detailed draft of your introduction. D. A funding application.

Answer **B.** The proposal converts the open-ended fear ("is this enough?") into a bounded agreement, and its scope-boundary sentence protects you from creep. A undersells its value. C is wrong — the introduction is rewritten last and looks nothing like the proposal. D confuses it with [Chapter 17](../chapter-17-grant-proposals/index.md)'s grant proposal. See §16.4.

4. Which is the single most important sentence to include in a thesis proposal?

A. A summary of every source you have read. B. The scope boundary — an explicit statement of what the work is not about. C. A guarantee that the results will be positive. D. A list of your qualifications.

Answer **B.** The written, agreed scope boundary is the cheapest insurance in graduate school — it is what you point to when scope creep arrives disguised as a helpful suggestion. An unwritten boundary is a wish, not a boundary. C is impossible and dishonest. See §16.4–16.5.

5. In a realistic two-year thesis schedule, the last third of the calendar is mostly:

A. Running the final experiments. B. Writing the first draft of the results chapters. C. Revision, advisor and committee feedback, and defense preparation. D. Choosing the topic.

Answer **C.** This scales [Chapter 5](../../part-01-writing-is-thinking/chapter-05-writing-process/index.md)'s "protect your revision time" to project length. Treating the deadline as the day the *writing* finishes — rather than the day the *revising and defending* finish — is the classic schedule-collapse error. See §16.5.

6. The literature-review chapter is hard primarily because it requires:

A. Reading more sources than anyone could manage. B. Synthesis — organizing sources by theme and argument toward a gap — rather than summary. C. Perfect grammar. D. Citing in IEEE format.

Answer **B.** It fails when it marches source-by-source ("X found…; Y found…"), which is summary, not synthesis ([Chapter 15](../chapter-15-literature-reviews/index.md)). Its thesis-specific job is to build the gap so airtight the reader becomes impatient for your contribution. See §16.7.

7. The standard that tells you what to include in (and cut from) the methodology chapter is:

A. Include everything you did, in order, all day. B. Reproducibility — a competent stranger should be able to replicate your work from the chapter alone. C. Brevity above all. D. Match the length of the results chapter.

Answer **B.** Reproducibility is the unforgiving standard: every choice that affects the result must be stated; every choice that does not can go (or move to an appendix). The methodology fails by including too *little* — the curse of knowledge hides "obvious" detail. See §16.7.

8. The literature-review and methodology chapters fail for opposite reasons. Those reasons are:

A. Too much detail in both. B. The lit review includes too much (every source); the methodology includes too little (omits reproducible detail). C. Both include too little. D. The lit review is too short; the methodology is too long.

Answer **B.** The same underlying principle — serve the reader, not the writer — points in opposite directions: ruthless *selection* toward an argument (lit review) versus exhaustive *specification* toward replication (methodology). See §16.7.

9. A thesis defense is primarily testing:

A. Whether your thesis is flawless. B. Whether you can recite your thesis from memory. C. Ownership — whether you understand and can justify your own choices and limitations. D. Whether your slides are well designed.

Answer **C.** The committee already knows the flaws; they are testing whether you do — whether the work is genuinely yours. For each major choice, be ready to say why this way, what alternatives you rejected, and what you'd do differently. See §16.8.

10. When asked about a real limitation during a defense, the strongest move is to:

A. Minimize it ("it's just an edge case") and pivot to your strengths. B. Name it, show where you acknowledged it, justify the trade-off, and point to bounded future work. C. Apologize and concede the thesis is flawed. D. Claim there are no limitations.

Answer **B.** Owning a flaw beats hiding it because the committee will find it regardless; the only variable you control is whether you found it first. Minimizing (A) signals you don't understand it; D destroys credibility instantly. See §16.8.

11. "While I'm at it, I might as well also test…" is flagged in this chapter as:

A. A sign of admirable thoroughness. B. A classic symptom of scope creep that should trigger the two-question test. C. The correct way to expand a thesis. D. Something only weak students say.

Answer **B.** It is "the most expensive seven words in graduate school." Run it through the two tests: does the claim fail without it? does the timeline survive it? If the claim survives without it, or the timeline doesn't survive it, it is future work. See §16.5.

12. Why are a thesis's introduction and conclusion usually finalized last?

A. They are the least important chapters. B. They must accurately describe an argument that doesn't fully exist until the middle chapters are done. C. They are the easiest to write. D. Committees don't read them.

Answer **B.** You discover your real contribution by doing the work; an early introduction is a guess. Writing it last lets you promise exactly what the thesis delivers — no over-promising. Sequence of *writing* differs from sequence of *reading* ([Chapter 5](../../part-01-writing-is-thinking/chapter-05-writing-process/index.md)). See §16.3.

Section 2 — True/False with Justification

State true or false and justify in one sentence.

T1. An original contribution requires an idea no one has ever had before.

Answer **False.** It requires *new, defensible knowledge* — a method, result, dataset, synthesis, refutation, or new application — and the ability to state in one sentence what is new. Most contributions are modest increments, and that is expected. (§16.1)

T2. A thesis statement that admits exceptions ("the method works except in fog") is weaker than one that claims to work always.

Answer **False.** Honest, bounded exceptions are a *strength* — they signal the scope was narrowed enough to be believed. A claim that works *always* is usually one that hasn't been scoped or tested honestly. (§16.2)

T3. The most common reason theses stall is intellectual difficulty — the ideas are too hard.

Answer **False.** The ideas are usually fine; theses stall on *scope and schedule* — scope too big to finish, all writing saved for the end. A thesis is a project-management problem as much as a writing one. (§16.5, §16.9)

T4. Because a thesis is long, some padding and restating are acceptable to reach the expected length.

Answer **False.** Length must come from a contribution that requires it, never from padding. Every extra page is a page the committee can question, so padding makes the defense *harder*. "Every sentence must earn its place" does not relax at 180 pages. (§16.9)

T5. Your advisor taking three weeks to return a draft is usually a verdict that your work is poor.

Answer **False.** It is usually a *queue*, not a verdict — advisors balance your thesis against grants, students, and teaching. Build weeks of turnaround into your schedule, and remember that a draft covered in red is an investment, while a thirty-second "looks fine" may mean it wasn't read. (§16.6)

T6. The proposal's introduction and the final thesis's introduction should be essentially the same document.

Answer **False.** The final introduction is written (or rewritten) *last*, because it must describe the contribution you discovered by doing the work — which the proposal could only guess at. Amara's final introduction looked nothing like her proposal's. (§16.3–16.4)

Section 3 — Short Answer

Two to four sentences each. A model answer and one-line rubric follow.

S1. A friend's thesis statement reads: "This dissertation studies the effects of social media on teenagers." In two or three sentences, explain why this will cause problems and give one specific narrowing question you would ask.

Model answer & rubric It is a *topic*, not a claim — "studies the effects of" cannot be wrong, defended, or known to be finished, and "social media," "effects," and "teenagers" are each the size of a career, so the project has no boundary and will wander for years. A narrowing question: *which* effect (sleep, anxiety, attention?), measured *how*, on *which* platform, for *which* teenagers? Forcing one answer to each deletes most of the possible thesis. **Rubric:** Names "topic vs. claim" + identifies the un-bounded breadth + asks a question that actually cuts scope.

S2. Explain, in your own words, why "future work" is not a graveyard but a useful tool for managing scope creep.

Model answer & rubric "Future work" is how you say *yes* to a good idea and *no* to the delay it would cause. When an addition is genuinely interesting but the thesis claim survives without it (or the timeline can't absorb it), naming it future work preserves the idea, credits its value, and keeps your project finishable. It converts a derailing temptation into an honest, generous place for ideas to wait until your next project. **Rubric:** Frames future work as a *decision tool* tied to the two-question test, not as discarding ideas.

S3. Why does owning a limitation beat hiding it in a defense? Give the mechanism, not just the advice.

Model answer & rubric The committee are experts who read the document, so they will find the weaknesses regardless — the only variable you control is whether you find them first. Surfacing a limitation proactively demonstrates the exact quality the defense tests (command of your own work) and converts an interrogation into a colleagues' conversation, whereas hiding it forces the committee to dig, and the digging is what feels adversarial. **Rubric:** Identifies "they'll find it anyway" + links proactive disclosure to demonstrating ownership.

S4. A student says: "I'll do all my research first, then write the whole thesis at the end." Name the two distinct dangers (one of them tied to this book's central thesis).

Model answer & rubric First, *writing is thinking* (the book's central thesis): you don't know whether your argument holds until you try to write it, so a fatal gap discovered while drafting at the end leaves no time to run the missing experiments. Second, a year of unwritten research is a year of accumulating risk — illness, a failed instrument, a competing publication — against a document that doesn't yet exist. The fix is to draft each results chapter as its experiments finish. **Rubric:** Both dangers present; one explicitly ties to writing-as-thinking; ideally names the fix.

Section 4 — Applied Scenario

A1 — Narrow and bound (rubric-graded). A first-year student hands you: "This dissertation will investigate how artificial intelligence can be used in education." Write (a) a single one-sentence claim that could be wrong and looks finishable in two to three years, and (b) a one-sentence scope boundary naming at least two specific exclusions.

Rubric - **Claim (4 pts):** Is it an assertion that could be false (not a topic)? Does it name a specific technique, task, audience, and a measurable outcome? Could you picture the evaluation? (Full marks only if all four.) - **Scope boundary (3 pts):** Does it name *specific* exclusions (not "other factors")? Are they framed as future work, not apologies? - **Finishability (1 pt):** Could a reasonable committee believe this is doable in 2–3 years? - *Strong example:* Claim — "An adaptive-hinting feature in an intro-programming tutor reduces time-to-correct on debugging exercises compared to static hints, for first-year non-majors." Boundary — "This work does not address grading automation, other subjects, or long-term retention; those are future work."

A2 — Defend an answer (rubric-graded). Examiner: "You only validated your method on one dataset. How do you know it generalizes?" Write a 3–4 sentence answer that demonstrates ownership.

Rubric - **Names the limitation honestly (3 pts)** — no minimizing ("it's fine"), no defensiveness. - **Shows it's already acknowledged / reasoned (2 pts)** — points to where you flag it, or explains *why* generalization is uncertain. - **Justifies the scoping decision (2 pts)** — why one dataset was the right call for a single thesis. - **Points to bounded next step (1 pt)** — names the future validation and how you'd do it. - A bluff or a pivot to strengths scores 0 on ownership regardless of polish.
