Write the purpose as one brief sentence that states the single aim of the study and keep it coherent with the title and problem statement.
Briefing
A strong research proposal hinges on three linked parts: a single-sentence purpose, specific objectives that translate that purpose into measurable actions, and research questions that can be answered through investigation. The core finding here is that these sections must be tightly coherent—each one should flow from the title and the problem statement, and together they determine what data will be collected, how it will be analyzed, and even which research design and instruments will be used.
The purpose of the study (section 1.3) is presented as one brief, concise statement that captures what the study intends to accomplish. It is often written as the “general objective” of the study in many institutions. Crucially, the purpose must be a single statement—having more than one purpose is treated as a structural error because the study is meant to address one problem. The purpose should also maintain coherence with the study title and the statement of the problem. An example is given where a title about comparing academic performance of bachelor of education science learners in distance versus on-campus modes at the University of Nairobi Kenya leads directly to a purpose that mirrors that comparison without adding extra aims.
Objectives (section 1.4) then narrow the purpose into specific statements of what the research will do to achieve it. Objectives provide direction and must show relationships between variables. They should be clear, unambiguous, brief, and aligned with the discipline. In social sciences, objectives are expected to be SMART—specific, measurable, attainable, realistic, and time-bound—and they are typically written using active verbs such as “to determine,” “to assess,” “to compare,” “to explore,” “to evaluate,” “to create,” “to differentiate,” and “to establish.” The transcript emphasizes that objectives must be measurable, which is why active verbs matter.
The examples illustrate how objectives connect to variables from the conceptual framework. One objective targets the relationship between the learning environment and academic performance across distance and on-campus modes, while another targets the relationship between demographic characteristics and academic performance. A further example distinguishes “relationship” from “influence”: establishing a relationship suggests a correlational survey approach, whereas determining influence may rely on descriptive statistics depending on how the analysis is framed.
Research questions (section 1.5) are described as investigative questions meant to be answered by the research, not yes/no prompts. They must align with the title, problem, purpose, and objectives; when the questions are answered, the objectives are achieved. In social sciences, the transcript highlights common questioning terms tied to problem types: “what is” and “how does” for descriptive or explanatory needs, and “to what extent” when a baseline exists and the study measures change against that reference point. It also stresses that research questions should be ordered to match the objectives, with each objective having a corresponding question. Finally, it warns against writing objective-style statements as research questions—questions like “does X influence Y?” are not research questions because they force yes/no responses; instead, objectives must be broken down into indicators derived from the conceptual framework for instrument development.
Overall, the lesson frames purpose, objectives, and research questions as a connected system: coherence prevents structural mismatch, and the wording of each section shapes design choice, instrument question types, and the logic of analysis.
Cornell Notes
The purpose of a study is a single, concise sentence stating what the research intends to achieve, usually treated as the general objective. Objectives translate that purpose into specific, measurable actions that show relationships between variables and should be SMART (specific, measurable, attainable, realistic, time-bound). Objectives are written with active verbs (e.g., determine, assess, compare) and must align with the discipline and the variables identified from preliminary literature and the conceptual framework. Research questions are investigative (not yes/no) and must match the title, problem, purpose, and objectives; answering them should achieve the objectives. Question wording (e.g., what is/how does/to what extent) signals the depth of inquiry and often affects the instrument design and analysis approach.
Why must the purpose of a study be written as a single statement, and how should it relate to the title and problem statement?
How do objectives differ from the purpose, and what makes an objective “measurable”?
What is the practical link between how objectives are worded and the research design or analysis approach?
How should research questions be constructed so they truly “investigate” rather than produce yes/no answers?
Why does the phrase “to what extent” require a baseline, and how does that affect analysis?
Review Questions
- How would you rewrite a study title into a purpose statement while ensuring coherence and avoiding multiple purposes?
- Given an objective about learning environment and academic performance, what research question wording would best match it (e.g., what is/how does/to what extent), and why?
- What is the difference between a research question framed as “does X influence Y?” and an investigative research question aligned to objectives and indicators?
Key Points
- 1
Write the purpose as one brief sentence that states the single aim of the study and keep it coherent with the title and problem statement.
- 2
Avoid multiple purposes; a well-structured proposal targets one core problem with one general purpose.
- 3
State objectives as specific, measurable actions that show relationships between variables and align with the discipline’s conventions.
- 4
Use active verbs in objectives (e.g., determine, assess, compare, explore, evaluate, establish) and ensure objectives are SMART.
- 5
Let objective wording guide design and analysis choices—for instance, “relationship” often aligns with correlational logic.
- 6
Form research questions as investigative (not yes/no) and match them to the objectives in the same order.
- 7
Do not copy objectives directly into research questions; break objectives into indicators from the conceptual framework for instrument development.
