The theoretical background section of a research paper serves to review and discuss the theories, models, hypotheses, published research or other scholarly works that are most relevant to the topic being investigated. This section aims to place the current study in the context of existing literature by summarizing what is already known about the topic. A well-written theoretical background sets the foundation for the rest of the paper by identifying gaps in knowledge, unanswered questions or inconsistencies in prior research that the present study aims to address.
When crafting the theoretical background, researchers should conduct a thorough literature review to uncover the seminal and most current theories and studies related to their research questions. Reviewing scholarly literature from a variety of sources such as peer-reviewed journal articles, books, conference presentations, and scholarly reviews will provide a well-rounded overview of the landscape of ideas regarding the topic. As relevant literature is evaluated, careful notes should be taken not just on the core findings and conclusions but also on how theories, models or hypotheses have evolved over time. Identifying trends, debates, and inconsistencies in findings will help establish the need and significance for the new study.
The theoretical background should be organized in a logical manner that flows cohesively. One approach is to begin with the broadest applicable theories and concepts before focusing in on literature most precisely related to the research problem. Another strategy is to present literature in chronological order to show how understanding of the topic has developed over years. Graphics like concept maps or diagrams can help illustrate relationships between various theories or concepts discussed. Regardless of structure, paragraph transitions should smoothly guide the reader through the review of prior research.
In presenting previous studies, provide thorough but concise summaries that synthesize key elements like methods, findings, limitations and conclusions. Avoid lengthy quotes or descriptions that disrupt the flow. Integrate relevant statistics, metrics or numeric data when helpful to underscore a point. When critiquing prior works, base any analysis on factual aspects of design, methodology or analysis rather than subjective opinions. Point out inconsistencies respectfully without accusations toward other researchers.
The theoretical background review culminates by explicitly stating the gap in existing research and literature that the current study aims to address. Clearly articulate how the research questions, methods or theoretical framework of the new project advances understanding beyond prior works. This establishes the significance and necessity of the study being proposed. The section should conclude by presenting specific hypotheses or research questions that logically stem from the identified gaps and aim to make an original theoretical or empirical contribution.
Well executed, the theoretical background provides crucial context for readers to comprehend how and why the new research adds value. It demonstrates the researcher’s capacity to thoughtfully and thoroughly analyze a body of literature. Students and early career researchers especially benefit from peer feedback and multiple drafts to hone their skills in evaluating and synthesizing theories into a cohesive narrative. With practice and experience, crafting a strong theoretical foundation will establish researchers as experts in their domains and lay the groundwork for meaningful contributions through their work.
