If you succeed in getting this part right, your research will gain a solid foundation and your dissertation’s purpose will become a lot more comprehensible to whomever reads your work.
When talking about theory, you might sometimes also hear the term “conceptual framework”.
The framework's narrative portion should communicate your hypotheses as well as any independent and dependent variables.
It could be as straightforward as the following -- this study examines the relationship between respondents' exposure to TV and radio campaign issue ads (independent variable) and their attitude towards that issue (dependent variable).
Developing a Theoretical Model To build a good quality theoretical model, you can use the following strategies: How to Structure a Theoretical Model Your theoretical model can be structured in different ways; there are no fixed rules regarding its layout and length.
Some opt for a more visual representation of concepts and their links, while others prefer to write out their model in a text format.
For the campaign issue ad study, the schematic could consist of three components.
On the left side, under the heading Independent Variables, there would be two boxes.
A good theoretical model should link your hypotheses with theories and concepts that were discussed in the literature review section of your work.
If you feel you need more general information on the focus of your literature review, it might be helpful to read the post describing the three different types of literature review.
