Is a theoretical framework the same thing as a conceptual framework, and does your thesis need both? Supervisors use the terms loosely, textbooks define them differently, and the proposal template at your department probably has a heading for one of them without saying what should go under it. The theoretical vs conceptual framework confusion is costly: committees return proposals because a theory is named and never used, or because a diagram of boxes and arrows floats free of any theory. This guide gives working definitions, a comparison table, a step-by-step method for building each framework, a worked example from an e-learning study with the diagram described in text, and the objections committees most often raise.

What is a theoretical framework, and what is a conceptual framework? A theoretical framework is the existing theory (or set of related theories) a study adopts to explain the phenomenon under investigation; it comes from the literature and brings its own concepts, assumptions and predictions. A conceptual framework is the researcher’s own structured representation of the specific concepts or variables the study will examine and the relationships expected among them, usually shown as a diagram. The theoretical framework explains why the relationships should exist; the conceptual framework shows which of them this particular study will test or explore.
Theoretical vs conceptual framework: how do the two differ?
| Dimension | Theoretical framework | Conceptual framework |
|---|---|---|
| Origin | Established theory from the literature (for example, the Technology Acceptance Model, Self-Determination Theory, the Theory of Planned Behavior) | Built by the researcher from theory, prior findings and the study context |
| Scope | General: explains a class of phenomena | Specific: the variables or concepts of this study and their links |
| Form | Narrative review of the theory, its constructs, assumptions and prior use | Diagram plus a short narrative defining each element and relationship |
| Function | Justifies why the relationships are expected and how findings will be interpreted | Operationalizes the study: what is measured or explored, and how the parts connect |
| Typical place | End of the literature review chapter, or its own section | End of chapter 2 or start of chapter 3, immediately before the hypotheses or research questions |
| Needed when | The study tests or applies theory, which is most quantitative and many qualitative theses | Almost always; even exploratory qualitative studies benefit from a provisional map (Maxwell, 2013) |
| Can it change during the study? | Rarely | Yes; in qualitative work it is revised as understanding grows |
Varpio and colleagues (2020) draw the same theoretical vs conceptual framework distinction for health professions education: theory is the explanation, the theoretical framework is the chosen theory applied to the problem, and the conceptual framework is the researcher’s justification of why this particular study matters and how its parts fit. Imenda (2014) adds a practical rule: a study built on a single theory can present its theoretical framework as the conceptual framework; a study drawing on several theories and empirical findings needs a separate conceptual framework that synthesizes them.
When do you need one, the other, or both?
- Quantitative, hypothesis-testing thesis: both. The theory supplies the constructs and the expected directions; the conceptual framework turns them into the variables you will measure and the paths you will test (Creswell & Creswell, 2018).
- Qualitative, exploratory thesis: usually a conceptual framework drawn from the literature and your own experience, which Maxwell (2013) calls a tentative theory of what is going on. A formal theoretical framework is added when a theory shapes the questions, for example a study of teacher motivation framed by Self-Determination Theory.
- Design, engineering or applied projects: often a conceptual framework alone, showing the components of the system or intervention and the criteria for evaluating it.
- Grounded theory: no theoretical framework at the outset by design, and the conceptual framework is a product of the study rather than an input. State this explicitly so that an examiner does not read the absence as an omission.
📱 Discuss your proposal idea with a specialist — You are told the specialist’s field and degree before work starts, and a meeting is scheduled to review your department’s requirements.
How do you build a theoretical framework?
- Name the core concepts in your problem statement and research questions. For “why do university teachers adopt or resist learning management systems”, the concepts are adoption, resistance, perceived benefits and context.
- Search for theories that explain those concepts. Use review articles and handbook chapters, not only empirical papers; note which theories dominate your field and which have been criticized.
- Evaluate candidate theories against four criteria: fit with your concepts, explanatory power for your question, evidence of prior use in similar settings, and feasibility of measuring its constructs with your sample.
- Select and justify. Write one paragraph on why the chosen theory fits and one on why the main alternative was rejected. Grant and Osanloo (2014) describe this as choosing the blueprint before building the house.
- Derive expectations. State the propositions the theory makes about your case; these become hypotheses in a quantitative study or sensitizing concepts in a qualitative one.
The write-up usually runs 1,500 to 3,000 words: the theory’s origin and development, its constructs with definitions, its main criticisms, how it has been applied to problems like yours, and precisely how you will use it.
How do you build a conceptual framework?
- List the concepts or variables your study will actually examine, with a one-sentence operational definition of each and the instrument or data source that captures it.
- Classify them: independent, dependent, mediating, moderating and control variables in quantitative work; central phenomenon, influencing conditions and consequences in qualitative work.
- Specify each expected relationship and its source: a theory, a prior finding or a reasoned argument from the context.
- Draw the diagram. Boxes for concepts, arrows for hypothesized directions, dotted lines for exploratory relationships, and a label (H1, H2) on each arrow that corresponds to a hypothesis.
- Check alignment: every research question or hypothesis must be visible in the diagram, and every arrow must appear in the analysis plan. Ravitch and Riggan (2017) describe the conceptual framework as the argument that connects the question, the literature and the method; an arrow that is never tested breaks that argument.
The narrative that accompanies the diagram is short, often one to two pages: what each element means, where each relationship comes from, and what is deliberately left out.
A worked example: e-learning adoption by university teachers
Research question: what explains university teachers’ intention to use a learning management system (LMS) for teaching, and does institutional technical support change the picture?
Theoretical framework: the Technology Acceptance Model (Davis, 1989), which proposes that perceived usefulness and perceived ease of use shape attitude toward using a technology, which in turn shapes the intention to use it. The student justifies TAM by its fit with voluntary adoption, its extensive use in education and the availability of validated scales, and rejects the Theory of Planned Behavior as the main lens because subjective norm was not central to the question, while keeping the idea of external support as an extension.
Conceptual framework, described in text: on the left, two boxes stacked vertically, “Perceived usefulness” and “Perceived ease of use”. Arrows from both run to a middle box, “Attitude toward using the LMS” (H1 and H2). A further arrow runs from perceived ease of use up to perceived usefulness (H3), as TAM proposes. From attitude, an arrow runs to the right-hand box, “Intention to use the LMS” (H4). Above the attitude-to-intention arrow sits a box, “Institutional technical support”, with a dotted arrow pointing at the H4 path to mark a moderating effect (H5). At the bottom, a small box lists the control variables, age, years of teaching and prior LMS training, with thin lines to intention.
| Hypothesis | Path in the diagram | Source |
|---|---|---|
| H1 | Perceived usefulness → attitude | TAM (Davis, 1989) |
| H2 | Perceived ease of use → attitude | TAM (Davis, 1989) |
| H3 | Perceived ease of use → perceived usefulness | TAM (Davis, 1989) |
| H4 | Attitude → intention to use | TAM (Davis, 1989) |
| H5 | Technical support moderates the attitude → intention path | Prior studies in higher education settings; reasoned extension |
Every hypothesis is an arrow; every arrow has a source; the analysis plan (regression for H1 to H4, a moderation test for H5) follows directly. That alignment is what a committee is checking.
How do you write them into the thesis?
Place the theoretical framework at the end of the literature review, after the empirical studies it helps to organize, or as a separate section if your template requires it. Place the conceptual framework immediately before the research questions or hypotheses, so that the reader meets the diagram and then the predictions it generates. Refer back to both in the discussion chapter: say which propositions the findings supported and whether the framework needs revision. A framework that disappears after chapter 2 reads as decoration.
Which objections do committees raise about the theoretical vs conceptual framework?
| Objection | What it usually means | Fix |
|---|---|---|
| “The theory is described but never used” | The theory section is a summary with no link to the questions | Add a paragraph deriving each hypothesis or sensitizing concept from a specific proposition of the theory |
| “This is a list of variables with arrows, not a framework” | The diagram has no theoretical justification | Attach a source to every arrow; remove arrows you cannot justify |
| “The diagram does not match the hypotheses” | Paths and hypotheses were written at different times | Number the arrows as H1, H2 and reconcile the table with the figure |
| “Two theories are glued together” | Constructs from different theories are mixed without integration | Explain the integration logic, or choose one theory and treat the other as the source of one added variable |
| “Where does the framework come back?” | The discussion does not revisit the framework | Add a section interpreting the findings against each proposition and proposing revisions |
| “The instrument does not measure the framework” | Questionnaire sections and constructs do not correspond | Build a specification table mapping each construct to its items |

Frequently asked questions
Can a qualitative thesis have a theoretical framework?
Yes. Many qualitative studies use a theory as a lens for the questions and the interpretation, for example framing an interview study with Self-Determination Theory. State how the theory shaped the questions and the analysis, and make clear whether you are testing it, applying it or allowing the data to challenge it.
Can I combine two theories?
You can, if you explain how they fit together and what each contributes that the other lacks. A common acceptable pattern is one main theory plus a single variable borrowed from another with a stated rationale. Avoid parallel summaries of two theories with no integration.
Do I need a diagram?
For a conceptual framework, almost always; committees expect one and it exposes misalignments quickly. The theoretical framework is normally narrative, though a figure of the original theory can help when you then show how your conceptual framework modifies it.
What is the difference between a conceptual framework and a research model?
In quantitative theses the terms are often used interchangeably. “Research model” tends to be used in information systems and business research for the diagram of hypothesized paths; “conceptual framework” is broader and includes the definitions and the rationale for each relationship.
Where does the framework go in a proposal?
Usually at the end of the literature review section, immediately before the research questions or hypotheses, so that the reviewer can see how the questions follow from it. Check your department’s template; some ask for a separate heading.
