This material aims to develop the argumentative writing competencies required in graduate education programs. Its organizing framework is the EEIR Model: State, Explain, Illustrate, Reason, which provides a coherent structure for constructing and evaluating academic arguments.
What Is an Academic Argument?
In graduate academic writing, an argument is not simply an opinion or a personal position. It is a rigorous intellectual construction that integrates evidence, logical reasoning, and field knowledge to support a claim before a specific academic community.
For a master’s student in education, arguing means participating in disciplinary conversations with one’s own voice: recognizing existing debates, positioning oneself critically in relation to them, and contributing with well-grounded analysis.
Core Definition
An academic argument is a structured series of claims supported by evidence and reasoning that seeks to persuade a specialized audience of the validity of a position on a debatable topic within a disciplinary field.
Arguing, Opining, and Informing
These three intellectual operations are frequently confused in graduate writing. The table below clarifies their differences:
| Type of writing | Main characteristic | Example in education |
| Informing | Presents data, facts, or concepts without taking a position. Describes the state of the question. | “Secondary school dropout rates increased 12% between 2018 and 2022.” |
| Opining | Expresses a personal position without the obligation to support it with systematic evidence. | “I think teachers should receive greater institutional support.” |
| Arguing | Defends a position with evidence, reasoning, and acknowledgment of the disciplinary debate. | “Ongoing teacher training policies significantly reduce school dropout when articulated with adequate working conditions (García & López, 2021).” |
The EEIR Model: State, Explain, Illustrate, Reason
The EEIR Model organizes the components of the academic argument into four interdependent operations: stating a thesis, explaining the reasons that support it, illustrating each reason with evidence, and reasoning through the link between evidence and claim.
This model applies both at the paragraph level—where each argumentative unit replicates the structure—and at the level of the full text, in which the global thesis is developed through articulated sections.
General Structure of the EEIR Model
STATE (Thesis or Claim) The main assertion the text defends: debatable, specific, and sustainable.
EXPLAIN (Reasons or Explanations) The secondary claims that answer the question: why is the thesis valid?
ILLUSTRATE (Evidence or Illustrations) The data, studies, examples, or theoretical arguments that demonstrate the validity of each reason.
REASON (Link with the Rest of the Argument) Explanation of relevance or link with the next claim.
STATE: The Thesis or Claim
The thesis—also called the central claim—is the main assertion the text seeks to defend. In graduate writing, the thesis must meet the following characteristics:
- Debatable: it cannot be a verifiable fact or an obvious truth.
- Specific: delimited in scope, context, and theoretical perspective.
- Arguable: capable of being supported with evidence from the field.
- Relevant: significant for the academic debate in education.
| Weak claim (avoid) | Strong claim (model) |
| Education is important for development. | Teacher training based on communities of practice improves learning outcomes in contexts of high social vulnerability (Wenger, 1998; Ávalos, 2011). |
| Teachers need more training. | The implementation of peer mentoring in initial teacher training reduces the gap between theory and pedagogical practice in the first years of professional practice. |
| Constructivism is a theory of learning. | The integration of the Vygotskian sociocultural approach in rural secondary education requires methodological adaptations that the current literature does not sufficiently address. |
| Technology changes education. | The use of digital platforms in multigrade classrooms reproduces or amplifies educational inequalities when not accompanied by contextualized teacher training. |
EXPLAIN: Reasons or Explanations
Reasons—also called explanations—are the secondary claims that justify the thesis. Each reason answers the question: why is the central claim valid? They must connect logically with the thesis and with each other.
Example of Reason Structure
Thesis (claim): Formative assessment improves deep learning in higher education.
Reason 1 (explanation): Because it enables timely feedback that adjusts the student’s cognitive processes.
Reason 2 (explanation): Because it promotes metacognition and self-regulation of learning.
Reason 3 (explanation): Because it reduces anxiety associated with summative assessment and encourages intellectual risk-taking.
ILLUSTRATE: Evidence or Illustration
Evidence—also called illustration—is the empirical or theoretical support that sustains each reason. In educational research, the types of illustration include the following:
| Type of evidence / illustration | Description | Typical sources in education |
| Quantitative empirical data | Statistics, test results, cohort analyses, measurements of educational variables. | Large-scale studies, PISA, experimental or quasi-experimental research. |
| Qualitative data | Narratives, interviews, observations, discourse analysis, case studies. | School ethnographies, educational phenomenology, action research. |
| Theoretical evidence | Conceptual frameworks, established theories, explanatory models of the field. | Sociocultural theory, curriculum theory, critical pedagogy. |
| Systematic review | Synthesis of multiple studies on the same educational phenomenon. | Meta-analyses, systematic reviews, state-of-the-art reviews. |
| Educational policy evidence | Normative documents, curricula, institutional assessments. | National policies, curricular frameworks, reports from international organizations. |
REASON: Bridge Between Illustration and Claim
The reasoning is the explicit link that explains how the evidence supports the reason and, ultimately, the thesis. In master’s academic writing, this link cannot be assumed: it must be stated clearly.
EEIR Formula Applied: State + Explain + Illustrate + Explicit Reasoning
STATE: Formative assessment improves deep learning.
EXPLAIN: Because it enables timely feedback that adjusts cognitive processes.
ILLUSTRATE: Black and Wiliam (1998) reviewed more than 250 studies and found that formative feedback practices produce significant gains in academic performance.
REASON: This finding is especially relevant in higher education because university students have greater metacognitive capacity to process and apply feedback, which amplifies the effect documented at earlier levels.
Additional Aspects
Acknowledging the Counterargument
A mature academic argument does not ignore opposing positions: it recognizes them, presents them fairly, and refutes them with evidence, or integrates them by qualifying the claim. This element distinguishes graduate writing from earlier levels.
- Concession: acknowledging the partial validity of a counter-argument.
- Refutation: showing why the counter-argument is incomplete, limited, or incorrect.
- Qualification: adjusting the claim to make it more precise in light of the critique.
Example of Concession and Refutation
“While it is true that implementing formative assessment requires additional planning time—which represents a real limitation in high-workload contexts (Torres, 2019)—longitudinal evidence indicates that the initial investment is offset by greater efficiency in subsequent cycles and a reduction in failure rates (Hattie & Timperley, 2007).”
Argumentative Models for Graduate Study
There are different frameworks for structuring academic arguments. The following are the most widely used in graduate writing in education sciences, and all are consistent with the logic of the EEIR Model.
The Toulmin Model
The problem Toulmin wanted to solve
Classical formal logic works with syllogisms: All men are mortal / Socrates is a man / therefore Socrates is mortal. This works well in mathematics or pure philosophy, but in real life—in law, in science, in political debate—arguments do not work that way. We almost never have absolute premises, and there are almost always exceptions, contexts, and degrees of certainty.
Toulmin said: we need a model that describes how people actually argue, not how they should argue in an ideal world.
The six components, with a single example
Imagine you argue: “Juan is probably a good teacher.”
| Component | What it does | In the example |
| Claim | What you want to prove | “Juan is a good teacher” |
| Data | The evidence you have | “Juan has ten years of experience and his students learn” |
| Warrant | The implicit logical bridge between data and claim | “Experience and learning outcomes are indicators of teaching quality” |
| Backing | Why to trust that warrant | Research on teacher effectiveness (Hattie, Darling-Hammond, etc.) |
| Qualifier | How strong the claim is | “Probably”—not absolute certainty |
| Rebuttal | When the claim does not apply | “Unless his methods are outdated or the context is very different” |
The central idea: arguments are “field-dependent”
This is perhaps the most original contribution. Toulmin observed that what counts as valid evidence changes by domain. In law, the standard is “beyond reasonable doubt.” In medicine, it is controlled clinical evidence. In education, it may be qualitative classroom studies. There is no single universal criterion of validity.
This was controversial at the time—logicians did not easily forgive him for abandoning formal logic—but it proved enormously influential in rhetoric, communication, and precisely in graduate academic writing.
| Component (Toulmin) | EEIR Equivalent | Function | Example in education |
| Claim | STATE / Thesis | The position being defended. | Ongoing teacher training reduces school dropout. |
| Data | ILLUSTRATE / Evidence | Information that supports the claim. | Ávalos (2011) shows a positive correlation between teacher professional development and student retention in Chile. |
| Warrant | Bridge of EXPLAIN | Principle connecting data to claim. | Teachers with greater professional development use more diverse and responsive pedagogical strategies. |
| Backing | Framework of ILLUSTRATE | Theoretical foundation of the warrant. | Theory of collective teacher efficacy (Bandura, 1997); communities of practice (Wenger, 1998). |
| Qualifier | Limit of STATE | Condition that bounds the claim. | Especially in contexts of high socioeconomic vulnerability. |
| Rebuttal | Counterargument | Condition that would limit the claim. | Unless training is not accompanied by decent working conditions and leadership support. |
The PEEL Model
The PEEL model does not have a single clearly identified author. It emerged as a practical pedagogical tool in academic writing instruction contexts in Australia during the 1980s, developed collectively by teachers, without any individual theorist publishing it as their own intellectual work.
It is informally attributed to the PEEL project (Project for Enhancing Effective Learning), a collaborative initiative by secondary school teachers in Melbourne who sought to improve their students’ writing and thinking. But it is more of a pedagogical convention that was consolidated and disseminated through its practical utility than a theoretical proposal with an author and reference text.
The PEEL model organizes each argumentative paragraph into four movements. Its correspondence with the EEIR Model is direct: Point = STATE, Evidence = ILLUSTRATE, Explanation = EXPLAIN, Link = articulation with the global thesis.
| Component (PEEL) | EEIR Equivalent | Function | Example |
| Point | STATE | Central claim or idea of the paragraph. | Formative feedback increases intrinsic motivation in learning. |
| Evidence | ILLUSTRATE | Data, citations, or examples that support the point. | Hattie (2009) identifies feedback as one of the highest-effect factors on educational achievement (d=0.73) in a meta-analysis of 800 studies. |
| Explanation | EXPLAIN | How and why the evidence supports the point. | When students receive specific information about their performance, they adjust their cognitive strategies and perceive greater control over their learning. |
| Link | Articulation | Connection to the thesis or the next paragraph. | Therefore, formative assessment not only improves academic performance but contributes to the development of autonomous learners—the central thesis of this work. |
The They Say / I Say Model
Gerald Graff and Cathy Birkenstein published They Say / I Say: The Moves That Matter in Academic Writing in 2006. Graff is an academic with an interesting trajectory: he was a professor of literature at the University of Chicago and is known, among other things, for arguing that universities should explicitly teach the conventions of academic discourse rather than taking them for granted. Birkenstein is his collaborator and shares affiliation with the University of Illinois at Chicago. The book grew directly from that conviction.
The central idea
Graff and Birkenstein start from a simple but powerful observation: weak academic writing tends to begin from scratch, as if the author were the first to think about the topic. Strong academic writing, by contrast, always enters into conversation with something that has already been said.
Their argument is that all academic texts, at their core, have this structure:
Someone argues X. However / Moreover / Therefore, I argue Y.
The “they say” is not decorative: it is what gives meaning and urgency to the “I say.” Without it, the argument floats in a vacuum.
Templates as a tool
The most distinctive feature—and the one that generated some controversy—is that the book offers literal templates for making these moves:
- “A number of scholars have argued that… However, I contend that…”
- “While X insists that… I agree/disagree because…”
- “This is not to say that… My point is rather that…”
Some critics said this mechanized writing. Graff and Birkenstein responded that the conventions of academic discourse already exist and are implicit: what the book does is make them visible for those who did not learn them through immersion. It is, in that sense, a democratizing project.
Why it connects well with the EEIR Model
The specific contribution of Graff and Birkenstein to the EEIR Model is that it resolves a question the model alone does not answer: where does the claim come from? The answer is: from listening first. The claim is not constructed in a vacuum but in response to what others have already said. This compels the writer to read the literature not as information to be summarized, but as interlocutors to be responded to, nuanced, or contradicted.
In practical terms for a master’s student: before writing your thesis, you need to know precisely what authors in the field say about your topic—not to cite them as decoration, but so that your claim is an intelligible response to that conversation.
They Say / I Say Structure Applied to the EEIR Model
THEY SAY (context of the claim): “Several authors argue that school failure has primarily socioeconomic roots and that pedagogical interventions have a marginal impact in contexts of high poverty (Coleman, 1966; Bourdieu & Passeron, 1977).”
I SAY (STATE): “However, research in culturally relevant pedagogy suggests that when teaching practice incorporates community funds of knowledge, the effects of structural inequality on learning can be significantly mitigated (González et al., 2005; Paris, 2012).”
EXPLAIN AND ILLUSTRATE: The reasons and evidence supporting this claim are developed below.
Constructing the Claim (Thesis)
The claim or thesis is the heart of the argument. In master’s writing, it is not the “topic” of the work but the specific, arguable position that will be defended through the explanations and illustrations of the text.
Characteristics of the Master’s-Level Claim
- Debatable: there are reasonable opposing positions in the literature.
- Specific: delimits the phenomenon, context, population, and approach.
- Analytical: goes beyond description and proposes an interpretation.
- Theoretically positioned: inscribed in a recognizable perspective of the field.
- Significant: contributes to the existing disciplinary debate.
- Sustainable: can be supported with available evidence and appropriate methodology.
Formulas for Constructing the Claim
The following formulas are starting points, not rigid templates. They serve to generate and evaluate preliminary versions of the central claim.
| Type | Formula | Example in education |
| Causal | [Phenomenon A] produces / increases / reduces [phenomenon B] in [context] because [mechanism]. | Teacher training in communities of practice increases student retention in vulnerable contexts because it strengthens the collective efficacy of the teaching staff. |
| Comparative | [Approach A] is more effective / relevant than [B] for [objective] in [context]. | Project-based learning is more effective than direct instruction for developing research competencies in graduate students in Latin American contexts. |
| Critical-evaluative | Although [dominant position], evidence indicates that [alternative position] in [specific conditions]. | Although school management models based on standardized metrics have dominated educational policy, qualitative evidence indicates that distributed pedagogical leadership generates a greater sustained impact on classroom improvement. |
| Propositional | [Documented problem] requires [intervention / approach] that [current literature does not yet address]. | Educational support for students with discontinuous migratory trajectories requires a flexible pedagogical model that current curricular regulations do not contemplate. |
Steps for Refining the Claim
- Identify the debate: What do authors in the field discuss about this topic? Read carefully for the points of tension, disagreement, or gap in the literature. The claim is born from that debate, not from a vacuum.
- Take a position: What is your response to the debate? Choose a well-grounded position, not simply a neutral or descriptive one.
- Specify the scope: Under what conditions is your claim valid? Add qualifiers that delimit context, population, and conditions of applicability.
- Test the claim: Could a reasonable person disagree? If no one in the field could disagree, the claim is not arguable: it is a fact or a tautology.
- Verify sustainability: Can you support it with explanations and illustrations? Check whether you have or can obtain sufficient evidence to sustain each reason that explains it.
Common Argumentative Errors in Graduate Study
Recognizing argumentative errors is a central competency in master’s writing, both to avoid them in one’s own texts and to identify them critically in the literature.
Structural Errors of the Argument
| Error | Description | How to correct it |
| Implicit claim | The text does not clearly state the position it defends. | State the thesis explicitly at the outset and recall it in the conclusion. |
| Circular argument | The conclusion restates the premise without adding new reasoning. | Introduce external evidence (illustration) that breaks the circle and justifies the reason. |
| Logical leap | The conclusion does not necessarily follow from the evidence presented. | Specify the reasoning that connects illustration to reason and reason to claim. |
| Overgeneralization | A universal conclusion is drawn from partial evidence. | Qualify the scope of the claim with explicit conditions and limits. |
| Straw man | A distorted version of the counter-argument is refuted. | Present the opposing position fairly and completely before refuting it. |
| Appeal to authority without illustration | A recognized author is cited without presenting the specific evidence they contribute. | Cite the author’s specific data or argument and explain its relevance to your claim. |
Argument Checklist (EEIR Model)
Checklist: State, Explain, Illustrate
STATE (Thesis or claim) ☐ My claim is debatable: it is not a fact or an obvious truth. ☐ My claim is specific and delimits context, approach, and scope. ☐ It is clearly stated in the introduction. ☐ It is revisited and reinforced in the conclusion.
EXPLAIN (Reasons or explanations) ☐ Each reason answers the question: why is my claim valid? ☐ The reasons are ordered with internal logic (from most general to most specific, or from lower to greater complexity). ☐ The reasoning connecting each reason to the claim is explicit. ☐ There are no logical leaps or unjustified generalizations.
ILLUSTRATE (Evidence or illustrations) ☐ Each reason is supported by at least one relevant illustration. ☐ Sources are current and appropriate to the disciplinary field. ☐ Evidence is cited correctly according to the indicated system (APA or other). ☐ I explain how each illustration supports the corresponding reason: I do not let it speak for itself.
COUNTERARGUMENT ☐ I acknowledge the relevant opposing positions in the field. ☐ I present them fairly, without distortion. ☐ I refute them with illustration, concede their partial validity, or qualify my claim.
Academic Language and Argumentative Connectors
Academic language for argumentation includes a repertoire of expressions that articulate the parts of the EEIR Model, signal the author’s position, and establish dialogue with the field’s literature.
Linguistic Resources by Function in the EEIR Model
| Function in the EEIR Model | Common expressions |
| STATE — Introducing the claim / thesis | This paper argues that… / The present analysis contends that… / Unlike what X proposes, it is argued here that… / The central thesis is that… |
| ILLUSTRATE — Introducing evidence | According to the data from… / As studies by… demonstrate… / The research by X confirms / suggests / indicates that… / The findings of X support this position by showing that… |
| EXPLAIN — Formulating explicit reasoning | This means that… / This implies that… / It follows that… / This finding is relevant because… / This data supports the claim given that… |
| COUNTERARGUMENT — Introducing the opposing position | Some authors argue that… / The dominant position in the field holds that… / It cannot be ignored that… / It is true that… |
| CONCEDE AND REFUTE | While it is true that X, the evidence suggests that Y… / Although X has validity in certain contexts, when… / Despite X pointing to real limitations, the analysis of Y indicates… |
| QUALIFY the claim | This conclusion applies especially when… / Results should be interpreted with caution given that… / In contexts where X, this argument may not apply because… |
Verbs for Citing with a Critical Position
In master’s writing, the way you introduce other authors’ ideas reflects your critical position toward them. It is not the same to say “X says” as “X demonstrates” or “X suggests without sufficient evidence.”
| Type of verb | Examples | When to use them |
| Neutral (reporting) | states, notes, indicates, mentions, describes, presents | To report without initially taking a position: basis for the “They say” section. |
| Supporting (strong ILLUSTRATE) | demonstrates, confirms, verifies, evidences, substantiates, validates | To present illustrations that directly support your reason or claim. |
| Arguing (another’s STATE) | argues, proposes, contends, defends, posits, postulates | To show that another author also defends an arguable position. |
| Questioning | questions, problematizes, critiques, refutes, contradicts, challenges | To show the debate or tensions in the field; basis for the counterargument. |
| Qualifying (weak ILLUSTRATE) | suggests, implies, points toward, tends to show, hints | To qualify the scope of an illustration: a sign of epistemic honesty. |
Application in Graduate Academic Genres
The EEIR Model applies specifically depending on the textual genre. In a master’s program in education, the most common genres are the following.
The Argumentative Essay
The argumentative essay is the central genre of graduate training. Its structure replicates the logic of the EEIR Model at the level of the full text.
| Section | Function in the EEIR Model | Expected content |
| Introduction | STATE | Contextualizes the debate, presents the relevance of the topic, states the central claim, and announces the structure of the argument. |
| Review of the debate | Context of STATE (They say) | Presents and analyzes existing positions in the literature, identifying agreements, tensions, and gaps that motivate the claim. |
| Development of the argument | EXPLAIN + ILLUSTRATE | Develops each reason with its evidence and reasoning, in logical order or increasing complexity. Each paragraph replicates the EEIR model. |
| Acknowledgment of counter-arguments | Counterargument | Presents the strongest objections and refutes them with illustration, or integrates them by qualifying the claim. |
| Conclusion | Revised STATE | Revisits the claim in light of the developed argument and identifies implications for practice, research, or educational policy. |
The Theoretical Framework as Argument
In a master’s thesis, the theoretical framework is not a summary of theories: it is an argument about which perspectives are most appropriate for analyzing the investigated phenomenon and why. It follows the logic of the EEIR Model.
Argumentative Structure of the Theoretical Framework (EEIR Model)
STATE: justification of the theoretical perspective adopted—why these concepts and not others?
EXPLAIN: articulation and definition of the central concepts—how do they relate to each other and why do they constitute the best scaffolding for this research?
ILLUSTRATE: dialogue with alternative perspectives—what other theories exist, what evidence supports each one, and why was the adopted perspective chosen?
Applicability: demonstration that the chosen concepts allow analysis of the phenomenon in this particular context.
The Discussion of Results as Argument
The discussion section in a thesis or research article is where the argument reaches its greatest complexity. It is not about repeating the results, but about arguing what they mean in relation to the literature.
- STATE: analytically formulate what the data reveal—do not describe them, interpret them.
- EXPLAIN: reason why what the data show occurs in light of the theoretical framework.
- ILLUSTRATE: connect findings with theory and contrast with studies in the field.
- Implications: draw consequences for practice, policy, or future research.
A closing reflection
Argumentation is not a skill reserved for advanced researchers or seasoned writers. It is the fundamental intellectual operation through which any researcher—at any level—makes their thinking visible, accountable, and open to dialogue. A master’s student who learns to state a defensible claim, explain the reasoning behind it, ground it in evidence, and engage honestly with opposing views is not simply learning to write better: they are learning to think in a way that the academic community can respond to, challenge, and build upon. This is what distinguishes a contribution from a report, and a researcher from a summarizer. The EEIR Model offered in this guide is not an end in itself—it is scaffolding. The goal is to internalize its logic so deeply that it eventually dissolves into the writing, leaving behind only the clarity of an argument that knows what it claims, why it claims it, and what it is willing to defend.
