Research & Credible Sources

Learning goals

• I can evaluate whether a source is credible using criteria like author expertise, publisher, and evidence of bias.
• I can paraphrase and cite information from a source without plagiarizing.

Not every source deserves your trust, and learning to tell a credible source from a shaky one is one of the most useful skills of the internet age. A credible source is accurate and trustworthy — usually written by someone with real expertise, published by a reputable organization, and willing to show the evidence behind its claims. To judge one, get in the habit of asking a few blunt questions.

Ask: Who wrote this — a named expert with relevant training, or nobody at all? Where was it published — an established, reviewed organization, or a random blog or anonymous post? Does it *show* its evidence, or just assert things? And does it show obvious bias — a slant toward one side that colors how fairly it presents information, or a sense that it's trying to sell you something? A source can be biased and still useful, but you need to know the slant is there so you can read it with clear eyes.

Good research isn't only about judging sources — it's about gathering well. Use specific, precise search terms instead of vague ones, and never lean on a single source. Check two or three on the same question, and treat any claim that seems surprising or too good to be true as a flag to verify elsewhere before you trust it. Real confidence comes from several solid sources agreeing, not from one lucky hit.

When you use what you find, you have to know the line between a true paraphrase and plagiarism. Plagiarism is presenting someone else's words or ideas as your own — and it's sneakier than just copying whole sentences. Swapping out a few words while keeping a source's original sentence structure and most of its vocabulary still counts as plagiarism, even though it 'looks' different. That near-copy is the trap students fall into most.

A true paraphrase, by contrast, means fully restating the idea in your *own* words and your *own* sentence structure — and here's the part people forget: you still cite where it came from, because the idea itself belongs to its original source even after you reword it. (Quoting works too, as long as you use quotation marks *and* cite.) These habits aren't just school rules: every time you fact-check something before resharing it online, you're using the very same credibility skills, and giving credit honestly is what separates real research from stealing.

Turn a broad topic into a question with a manageable place, time, population, and purpose. A question should require inquiry rather than assume its answer.

Plan sources by the information they can supply: firsthand records, scholarly or professional interpretation, and competing positions. Keep a search log with queries, decisions, and gaps.

Revise the question when evidence changes the scope. An unanswered question is not failure; document what the available sources cannot establish.

A practical method: read once for literal understanding, mark a relevant detail, write a tentative response, then test it against another detail. In a language task, identify the intended meaning before changing the sentence. In a research task, record what each source actually establishes before synthesizing.

For Grade 8, the application expectation is: Explain one inference with two details. Use a short quotation and your own reasoning. Plan a response of about 120–180 words when a task calls for a developed paragraph; a sentence-editing task may need much less. These lengths guide planning rather than replace the success criteria.

This unit connects to the course reading library. The story “The Spare Key” develops this grade’s inquiry into trust, community & responsibility. The argument packet includes differently situated sources; distinguish fictional exercise evidence from historical records in your book study.

Worked examples

Avoid these mistakes

• “Why are all public displays misleading?”
• The question assumes a universal answer. Specify a display and ask how excerpt selection affects the representation of speakers.
• Treating a model answer as the only acceptable wording or using an unattributed quotation.

Words to know

credible source

A source that is accurate and trustworthy, typically written by someone with real expertise or backed by solid evidence.

bias

A slant toward one side that can affect how fairly information is presented.

plagiarism

Presenting someone else's words or ideas as your own without giving credit.

paraphrase

Restating someone else's idea fully in your own words and sentence structure, while still citing where it came from.

Primary vs. secondary sources: why the best research uses both

A primary source is firsthand — original data, a direct interview, an original document, a raw dataset. A secondary source analyzes or summarizes primary sources — a news article explaining a scientific study, for instance, rather than the study itself. Secondary sources are often easier to read and helpful for context, but they add a layer of interpretation (and sometimes error) between you and the original information. Strong research usually uses secondary sources to get oriented, then checks claims against primary sources when precision matters — rather than relying on secondhand summaries alone.

Credible... but outdated: currency as a hidden fourth credibility check

Author expertise, publisher reputation, and evidence are the standard credibility checks — but for fast-changing topics (technology, health guidelines, population statistics), there's a fourth check: currency, meaning how recent the source is. An article by a genuine expert, published by a reputable outlet, can still mislead readers if it's ten years out of date on a topic that's since changed significantly. Always check a source's publication date and ask whether the topic is the kind that could have shifted since then.

Patchwriting: the sneaky near-plagiarism that swaps a few words

There's a specific, common trap between honest paraphrasing and outright copying, sometimes called patchwriting: keeping a source's original sentence structure and most of its vocabulary, but swapping in a synonym here and there. 'Sea levels have risen approximately eight inches since 1900' patchwritten becomes 'Ocean levels have gone up about eight inches since 1900' — different enough to feel like your own words, but still built on the original's exact structure and reasoning. True paraphrasing rebuilds the sentence's structure entirely, not just its word choices.

Mini-analysis: spotting patchwriting versus a true paraphrase

Original source sentence: 'Researchers discovered that students who read for pleasure for at least twenty minutes daily showed measurably stronger vocabulary growth over a single school year.' Patchwrite (too close): 'Scientists found that kids who read for fun for a minimum of twenty minutes every day showed noticeably better vocabulary development across one school year.' True paraphrase: 'A year-long study found a clear link between daily pleasure reading and vocabulary gains, even with just twenty minutes a day (Author, Year).'

The patchwrite keeps the original's sentence shape and swaps synonyms one-for-one ('researchers' becomes 'scientists,' 'discovered' becomes 'found'). The true paraphrase restructures the idea completely, states it in a genuinely new sentence, and adds a citation. Only the true paraphrase would be considered original writing that properly credits its source.

Common mistake: not knowing what counts as 'common knowledge'

Not every fact needs a citation — widely known information, like 'World War II ended in 1945' or 'the heart pumps blood,' is considered common knowledge and doesn't require one. But a specific statistic, a particular study's conclusion, or an expert's original analysis absolutely does, even if you paraphrase it perfectly. A useful test: if you learned the fact from one specific source and couldn't have written it without that source, cite it. If it's the kind of fact found unchanged in dozens of general references, it's likely common knowledge.

In the real world

Every time you fact-check something you saw on social media before sharing it, you're using these same credibility-evaluation skills.
