1. Purpose of the tool
TopicLab AI is both an AI writing assistant and a learning tool. It helps you understand how to build a strong postgraduate research topic by identifying the independent variable, dependent variable, research site, and research participants.
The tool also helps you generate one quantitative research question, one qualitative research question, a general objective, specific objectives, the scope of the study, and feasibility warnings.
2. Research approach
TopicLab AI uses a fixed mixed-methods approach. This means the tool will always generate one quantitative research question and one qualitative research question.
The quantitative question should be answerable with measurable data such as questionnaires, test scores, rubric scores, rating scales, or SPSS analysis. The qualitative question should be answerable with interviews, open-ended responses, classroom observation, reflective journals, or thematic analysis.
3. Area of interest
Students can choose one of the following core areas: Speaking, Reading, Writing, Listening, Vocabulary, Grammar, or Pronunciation.
If your research idea does not fit these areas, select Other and type your own area of interest, such as AI in language education, translation studies, learner motivation, teacher professional development, or online learning.
4. How to enter a raw research idea
Your raw research idea does not need to be perfect. You can write it naturally, even if it is still informal or incomplete.
TopicLab AI will refine this idea into a more academic and researchable mixed-methods topic.
5. How to define independent and dependent variables
The independent variable is the factor that may influence, support, or explain change. The dependent variable is the outcome you want to measure, describe, or understand.
Independent variable: AI writing tools
Dependent variable: academic writing performance
Avoid vague dependent variables such as “student success”, “better English”, or “learning improvement”. Use more measurable outcomes such as writing performance, speaking fluency, vocabulary retention, grammar accuracy, pronunciation intelligibility, reading comprehension, listening comprehension, learner motivation, or perceived usefulness.
6. How to choose research participants and research site
Research participants are the people who will provide data for your study. Research site refers to the place or context where the study will be conducted.
Research participants: English-major postgraduate students
Research site: HUFLIT
A strong topic should clearly state both. This makes the study more focused, realistic, and suitable for a postgraduate thesis or research proposal.
7. How to describe the research problem
The research problem explains why the study is necessary. It should describe a real difficulty, gap, challenge, or issue that your study aims to investigate.
A good research problem should be specific enough to guide the research questions and data collection methods.
8. How to interpret the generated research topic
After you click Generate Research Topic, TopicLab AI will produce a refined mixed-methods research topic and a topic components table. Read the table carefully because it shows whether your topic has the essential components of a researchable topic.
A complete topic should include:
- Independent variable: the factor or intervention being studied
- Dependent variable: the outcome being measured or explored
- Research site: the context or location of the study
- Research participants: the people who will provide data
9. How to use the suggested research questions
TopicLab AI gives you two research questions because the tool is designed for mixed-methods research.
- RQ1 – Quantitative: This question should be answered with measurable data, such as questionnaire results, test scores, rubric scores, rating scales, or SPSS analysis.
- RQ2 – Qualitative: This question should be answered with interpretive data, such as interviews, open-ended responses, observation notes, reflective journals, or thematic analysis.
You can revise these questions with your teacher or thesis supervisor before using them in your official research proposal.
10. How to use the objectives
The general objective states the main purpose of the study. The specific objectives break the study into smaller research tasks.
Good specific objectives often begin with academic verbs such as:
- To examine
- To identify
- To investigate
- To explore
- To evaluate
- To determine
11. How to use the scope of the study
The scope section helps you narrow your research. It may suggest how to limit the participants, site, variables, data collection period, quantitative data, and qualitative data.
This section is important because many student topics are too broad at the beginning. A clear scope makes the study more feasible.
12. Suggested mixed-methods design
TopicLab AI may recommend one of the following mixed-methods designs:
- Explanatory sequential design: collect quantitative data first, then use qualitative data to explain the results.
- Exploratory sequential design: collect qualitative data first, then develop or refine quantitative instruments.
- Convergent parallel design: collect quantitative and qualitative data during the same phase and compare the findings.
The suggested design is only a recommendation. You should discuss it with your teacher or supervisor before finalizing your research proposal.
13. Common mistakes to avoid
- Choosing a topic that is too broad.
- Using vague outcomes such as “improve English” or “student development”.
- Not specifying the research site.
- Not specifying research participants.
- Writing research questions that do not match mixed-methods research.
- Using a dependent variable that is difficult to measure.
- Planning a study that is too ambitious for a postgraduate thesis timeline.
- Confusing a teaching activity with a researchable variable.
14. Example input and output
Example input
Raw research idea: I want to study how AI writing tools help students improve academic writing.
Area of interest: Writing
Research participants: English-major postgraduate students
Research site: HUFLIT

Research approach: Mixed-methods
Possible refined topic
Possible topic components
Independent variable: AI writing tools
Dependent variable: academic writing performance
Research site: HUFLIT
Research participants: English-major postgraduate students
Area of interest: Writing

- RQ2 – Qualitative: How do English-major postgraduate students perceive the usefulness of AI writing tools in improving their academic writing?
15. Final reminder
TopicLab AI provides a strong first draft, but your final research topic should still be reviewed by your teacher or thesis supervisor. A good postgraduate research topic must be clear, researchable, measurable, feasible, and methodologically appropriate.
