Academic Research Vocabulary
Part of the Science & Technology vocabulary group in Teacher-In-A-Box, this lesson explores the vocabulary used to describe the research process, sources and evidence, writing and citation, methodology, and publishing and peer review — language useful for talking about academic work in almost any field or institution.
Connected vocabulary, not a glossary
Academic research vocabulary works as a system.
Talking about academic research means talking about how an idea is tested (hypothesis, theory), where information comes from (source, evidence), how other people’s work is acknowledged (cite, quote), how a study is designed (methodology, sample), and what happens once the work is finished (publish, peer review).
This lesson groups vocabulary by what it’s used to describe — the research process, sources and evidence, writing and citation, methodology, and publishing and peer review — and shows how the words in each area relate to and differ from one another. Citation styles, methodologies, and publishing conventions vary between fields and institutions, so this lesson focuses on vocabulary that applies to academic research in general rather than one specific field or style guide.
You will leave this lesson able to talk about academic work more precisely, whatever field or institution it takes place in.
1. The research process
Vocabulary for how an idea moves from a question to an answer.
research — careful, systematic study of a topic in order to discover new information: “Her research took over a year to complete.”
data — facts or information, especially numbers, collected for analysis: “The data showed a clear pattern.”
analyze — to examine something carefully in order to understand it: “He analyzed the results before writing his conclusion.”
hypothesis vs. theory
hypothesis / theory — a hypothesis is a specific, testable proposed explanation or prediction that can be investigated using evidence; a theory is a broader explanatory framework supported by a substantial body of evidence: “Her hypothesis was tested through several experiments, while the broader theory it related to had already been supported by decades of research.”
2. Sources and evidence
Vocabulary for where information comes from.
source — a document, person, or record that provides information: “She checked several sources before writing her summary.”
evidence — facts or information that support a claim or conclusion: “The evidence supported her hypothesis.”
reliable — able to be trusted, based on how the information was gathered: “He preferred reliable sources over ones he couldn’t verify.”
primary source vs. secondary source
primary source / secondary source — a primary source is original or firsthand material or evidence produced by the people, research, event, experiment, observation, or period being studied, such as an original research article, a dataset, an interview, or a historical letter; a secondary source analyzes, interprets, discusses, or summarizes primary sources or original research rather than being one itself: “She read a secondary source first, then went back to the primary research it discussed.”
3. Writing and citation
Vocabulary for acknowledging other people’s work.
paraphrase — to restate someone else’s idea in your own words: “He paraphrased the article instead of copying it directly.”
reference — a note that identifies where information came from: “Each reference appeared in a list at the end of the paper.”
citation — a formal way of crediting a source, often following a specific style: “Her citations followed the format required by her department.”
cite vs. quote
cite / quote — to cite is to credit a source for an idea, whether or not you use its exact words; to quote is to reproduce someone’s exact words, usually in quotation marks: “She quoted one sentence directly and cited the rest of the article for background.”
4. Methodology
Vocabulary for how a study is designed.
methodology — the overall approach and set of methods used in a piece of research: “She explained her methodology in the second chapter.”
method — a specific technique or procedure used to collect or analyze information: “He used a different method to check his results.”
sample — the people, items, cases, or observations selected for study; in some research, the sample is intended to represent a larger population: “The study’s sample included people from several regions.”
qualitative vs. quantitative
qualitative / quantitative — qualitative research focuses on descriptions, opinions, and experiences that aren’t primarily numerical; quantitative research focuses on numerical, measurable data: “She combined qualitative interviews with a quantitative survey.”
5. Publishing and peer review
Vocabulary for what happens once the work is finished.
How a paper is reviewed, formatted, and published varies between fields and institutions, so this lesson focuses on the general vocabulary rather than any one process.
publish — to make written work publicly available: “She hoped to publish her findings by the end of the year.”
journal — a publication, often periodic, that shares research within a field: “His article appeared in a well-known journal.”
peer review — a process in which other experts in the field evaluate a piece of research before it’s published: “The paper went through peer review before it was accepted.”
Vocabulary in context
See the vocabulary working together.
Here is a short passage using several words from this lesson together.
She began with a hypothesis about how the two factors were related, then reviewed several primary and secondary sources for background. After collecting her data, she chose a qualitative methodology to analyze it, carefully citing every source she used along the way. Once her draft was ready, she revised it several times before submitting it to a journal, where it underwent peer review.
Unpacking what this vocabulary communicates:
hypothesis about how the two factors were related → describes a specific, testable proposed explanation guiding the research.
primary and secondary sources → describes gathering both original and analytical material.
qualitative methodology…citing → describes both the research approach and the practice of crediting sources.
draft…revised…journal…peer review → describes the stages between finishing writing and formal publication.
The passage doesn’t name a specific field, institution, or citation style, so the vocabulary can be applied to almost any academic project.
Don’t confuse these
Choosing the right word changes what a sentence communicates.
hypothesis / theory
A hypothesis is a specific, testable explanation or prediction; a theory is a broader explanatory framework supported by substantial evidence.
primary source / secondary source
A primary source is original or firsthand material or evidence, such as a dataset, interview, or original article; a secondary source analyzes, interprets, or summarizes primary sources or original research.
cite / quote
To cite is to credit a source generally; to quote is to reproduce someone’s exact words.
qualitative / quantitative
Qualitative research focuses on descriptions and experiences; quantitative research focuses on numerical, measurable data.

Common errors
Mistakes are useful when you understand why they happen.
I did a research on this topic.
I did research on this topic.
“Research” is normally uncountable, so it doesn’t take the article “a.”
I need to research about the topic more deeply.
I need to research the topic more deeply.
As a verb, “research” is followed directly by its object — no “about” is needed.
The theory is based in strong evidence.
The theory is based on strong evidence.
The fixed preposition is “based on,” not “based in.”
Peer review make the process more reliable.
Peer review makes the process more reliable.
“Peer review” is treated as a singular subject, so the verb needs an “-s.”
She cite three sources in her essay.
She cited three sources in her essay.
Use the simple past tense “cited” to describe a completed action.

Quick review
Five areas, connected by the process of academic research.
The research process — hypothesis vs theory, plus research, data, and analyze.
Sources and evidence — primary source vs secondary source, plus source, evidence, and reliable.
Writing and citation — cite vs quote, plus paraphrase, reference, and citation.
Methodology — qualitative vs quantitative, plus methodology, method, and sample.
Publishing and peer review — publish, journal, peer review, draft, and revise.
Watch for — hypothesis vs theory, primary vs secondary source, cite vs quote, qualitative vs quantitative.
Remember
Citation styles and publishing conventions vary between fields and institutions, but the vocabulary for talking about research stays widely useful.
Which citation style, methodology, or journal someone uses depends on their field, but vocabulary such as hypothesis, cite and peer review is useful across almost any academic context.
