Rewriting a 12% Turnitin Flag in APA 7 for Your Thesis

What does “paraphrasing” actually mean in APA 7?

When your supervisor says the sentence structure is too close to the source, they are talking about the core of APA 7 paraphrasing rules. The module guide will list “paraphrase with your own words and sentence flow” as a rubric item, and the plagiarism‑detection software looks for patterns that match the original beyond a handful of word swaps. A proper paraphrase therefore does three things:

• Changes the order of ideas, not just the order of words.
• Uses synonyms that fit the discipline’s terminology – you can’t replace “photosynthesis” with “light‑driven carbon fixation” if the source already uses that phrase.
• Credits the source with an in‑text citation that matches the reference list.

Imagine you are drafting a paragraph on wetland carbon sequestration. The source sentence reads: “Temperate wetlands store up to 0.5 t C ha⁻¹ yr⁻¹, making them significant carbon sinks.” A weak paraphrase might become: “Temperate wetlands store up to 0.5 t C ha⁻¹ yr⁻¹, making them important carbon sinks.” You have only swapped “significant” for “important,” which Turnitin will flag. A strong paraphrase could read: “In temperate zones, wetlands can capture half a tonne of carbon per hectare each year, thereby acting as notable carbon reservoirs.” The meaning is the same, but the grammatical skeleton is different, and the citation (Smith, 2022) follows the APA 7 author‑date format.

Notice the shift from a noun‑heavy construction (“wetlands store”) to a verb‑focused one (“wetlands can capture”). That shift is what graders look for when they circle “paraphrase” on the rubric. If you keep the original clause order, even with synonym swaps, you risk a “minor plagiarism” flag. The key is to rewrite the thought as if you were explaining it to a peer who hasn’t read the source.

Why does my Turnitin similarity report still flag paraphrased text?

Turnitin doesn’t just count identical words; it runs a linguistic algorithm that detects “matching phrase patterns.” The software assigns a similarity percentage based on three layers: exact string matches, near‑matches, and citation‑matched quotations. Your 12 % flag likely lives in the near‑match bucket because the algorithm recognized the same syntactic skeleton you kept.

One technical dead end many students hit is leaving the “exclude bibliography” box unchecked. That adds every reference entry to the similarity total, inflating the percentage without meaning any plagiarism. Another common mistake is using the “quick‑save” version of your draft that still contains highlighted notes from your supervisor. Those notes often repeat source wording verbatim and get counted.

To see the exact source of each match, click the “view” button in Turnitin and examine the “Match Overview.” You’ll notice a highlighted block that mirrors your own sentence structure. If the block is under 10 words but still flagged, it’s a sign the algorithm is sensitive to phrase order. The solution is to rewrite that block entirely, not just replace a couple of words.

In practice, a senior environmental science student discovered that changing “the rate of nitrogen leaching” to “the speed at which nitrogen leaches” left the similarity unchanged because the phrase order remained identical. After re‑ordering the clause to “Nitrogen leaches more quickly when…,” the match disappeared. The lesson is clear: you must alter the grammatical backbone, not just the vocabulary.

How can I rewrite to avoid plagiarism while keeping my voice?

Start by summarizing the source in a single sentence without looking at the original. Then compare your summary to the source and ask: does my version use a different subject‑verb arrangement? Does it incorporate a transition that reflects your own argument flow? If the answer is yes, you’re on the right track.

Below is a quick checklist you can run through for each paragraph of your literature review:

1. Read the source, close the article, and write the idea in your own words.
2. Identify any discipline‑specific terms that must stay unchanged (e.g., “eutrophication,” “biogeochemical cycle”).
3. Insert an APA 7 in‑text citation immediately after the paraphrase.
4. Compare your sentence to the source: if more than half the clauses are in the same order, rewrite again.
5. Run the paragraph through Turnitin’s “draft‑only” view to confirm the similarity drops below 5 % for that block.

When you hit a stubborn sentence, try the “question‑answer” trick: turn the original statement into a question, answer it in your own words, and then embed the citation. For example, the source claim “Climate models predict a 2 °C rise by 2100” becomes “What do climate models forecast for the next century? They anticipate an average warming of about two degrees Celsius (Jones, 2021).” This forces you to restructure the information.

One common mistake is over‑quoting short phrases that are not unique to the source. In environmental science, phrases like “greenhouse gas emissions” appear everywhere. If you quote them, you waste citation space and raise the similarity score unnecessarily. Instead, treat such generic terms as common knowledge and only cite when the surrounding analysis is specific to the source.

What’s a realistic schedule to overhaul my literature review?

Time pressure is the real enemy of good paraphrasing. Break the task into bite‑size chunks and assign a deadline to each. Here’s a skeleton you can start tonight:

• Day 1 (2 hours): Export the Turnitin report, highlight every flagged block, and copy the original source sentences into a spreadsheet.
• Day 2 (3 hours): For each highlighted block, write a one‑sentence summary without looking at the source.
• Day 3 (2 hours): Transform each summary into a full paragraph, inserting APA 7 citations as you go.
• Day 4 (1 hour): Run the revised sections through Turnitin’s draft check; note any remaining matches.
• Day 5 (2 hours): Polish language, ensure consistent tense, and double‑check the reference list formatting.

Adjust the hours based on your other coursework, but keep the sequence intact. Skipping the “write a summary without looking” step is the fastest route to another 12 % flag, because you’ll be tempted to copy the original phrasing.

If you find a particularly dense paragraph, allocate an extra 30 minutes on Day 3 to split it into two smaller ideas. The goal is to finish with a version that, when you run the final check, shows a similarity score under 5 % for the literature review portion.

Story 1: The cautious paraphraser who rewrote everything

A sophomore in environmental science submitted a draft literature review that scored 12 % similarity. The supervisor warned that the sentence structures mirrored the sources too closely. The student spent a weekend reading each source, then wrote a one‑sentence “idea note” for each paragraph, deliberately avoiding the original wording. After a full rewrite, the Turnitin report dropped to 3 %. The supervisor praised the fresh voice and the clear citation style. The student learned that “changing every third word” is not enough; you need to rebuild the logical flow.

What happened next? The revised draft earned a “Pass with Distinction” on the rubric’s “Paraphrase Quality” row, which required a score of 4 / 5. The student also discovered that the “exclude bibliography” box in Turnitin saved an extra 2 % similarity that would have otherwise been deducted from the final grade.

Story 2: The shortcut seeker who kept the original skeleton

A senior who juggled a part‑time job tried to meet the deadline by swapping synonyms in the original text. The revised paragraph still read, “Temperate wetlands store up to 0.5 t C ha⁻¹ yr⁻¹, making them significant carbon sinks,” with only “significant” changed to “major.” Turnitin flagged the same block, and the supervisor returned the draft with a note: “Rewrite the sentence structure, not just the words.” The student rushed a second rewrite, but kept the same clause order, leading to a second similarity flag of 9 %.

After a meeting with the writing center, the student learned to use the “question‑answer” method and to break the paragraph into two separate ideas. The final version read: “In temperate regions, wetlands can capture half a tonne of carbon per hectare each year. This capacity makes them valuable carbon reservoirs (Lee, 2020).” The similarity fell to 4 %, and the supervisor marked the work as acceptable, though with a comment to watch future drafts.

Which story matches your situation and what should you do next?

If you spent the night swapping synonyms and still got a 12 % flag, you are in the “shortcut seeker” camp. The immediate step is to identify the flagged sentences, write a brief idea note for each, and then reconstruct the sentence using a different grammatical pattern. If you already drafted a full rewrite but are unsure about the structure, you belong to the “cautious paraphraser” group. In that case, run a final Turnitin check on each paragraph individually to catch any lingering near‑matches.

Both stories converge on three practical lessons:

• Never rely on word‑level changes; focus on clause‑level restructuring.
• Always include an APA 7 in‑text citation right after the paraphrase.
• Use Turnitin’s draft mode to verify each block before the final submission.

Pick the checklist from the “Integrity Fear” section and apply it to the flagged sentences. If you finish the rewrite within the five‑day schedule, you’ll have a polished literature review ready for your supervisor’s final sign‑off.
