Introduction to Qualitative Research Methods

Introduction to Qualitative Research Methods

  • Definition: Involves the collection of non-numerical data to understand concepts, experiences, or perceptions.

Quantitative Study

  • Definition: Research that uses numbers as data and statistical analysis to measure relationships or differences between variables.
  • Characteristics:
    • Objective data (e.g., scores, frequencies, percentages).
    • Large sample sizes (30 participants and above).
    • Structured methodology (surveys/control experiments).
    • Data analysis using statistical methods.
  • Example Question: "How often do students use AI weekly?"

Qualitative Study

  • Definition: Research involving the collection of data (words, observations) to understand context, experiences, or perceptions.
  • Characteristics:
    • Subjective data (e.g., interviews, field notes).
    • Small sample sizes (10-20 participants).
    • Flexible approach (open-ended questions).
    • Analysis of words to understand meaning.
  • Example Question: "How do rural students describe their first experience with AI?"

Quantitative Research Steps

  1. Identify Topic
  2. Read Literature Review
  3. Build Hypothesis
  4. Conduct Survey/Experiment
  5. Test Hypothesis
  6. Write Report

Qualitative Research Steps

Theoretical Considerations

  • Strengths and Weaknesses of Approaches:
    • Quantitative:
    • Strengths: Suitable for testing theories, structured and systematic.
    • Weaknesses: Limited to existing theories, less flexible in study approach.
    • Qualitative:
    • Strengths: More flexible, can generate new theories/assumptions.
    • Weaknesses: Less systematic, harder to prove theories.

Exploratory Research

  • Definition: Research aiming to gain initial understanding and identify real issues for further research.
  • Characteristics:
    • Conducted on new, poorly understood topics with little previous study.

Descriptive Research

  • Purpose: Answers questions such as “what,” “who,” “when,” “where,” and “how,” but not “why.”
  • Characteristics:
    • Flexible, open structure without strict guidelines.
    • Does not require hypothesis testing.
    • Often involves qualitative data collection methods (e.g., in-depth interviews, focus groups).
    • Inductive approach to understand new phenomena.

Explanatory Research

  • Definition: Aimed at identifying causes, relationships, or effects between two or more variables.
  • Characteristics:
    • Focuses on "why" and "how" phenomena occur.
    • Tests hypotheses based on empirical data.
    • Systematic design to reduce bias, typically using quantitative methods.
    • Deductive approach building from existing theory.

Comparative Research Approaches to AI Use Among Rural Students

  • Exploratory Research:

    • Investigates awareness of AI among rural students.
    • Example Question: "Are rural students aware of ChatGPT?"
    • Flexible design, no initial hypothesis.
  • Descriptive Research:

    • Analyzes the extent and frequency of AI use.
    • Example Question: "How often do rural students use AI for school work?"
    • Structured surveys or observations.
  • Explanatory Research:

    • Investigates reasons for low AI usage (e.g., internet access, awareness).
    • Example Question: "Does lack of internet access hinder AI use?"
    • Employs experiments or statistical analysis and interviews with students/teachers.

Advantages of Qualitative Research

  • In-depth Understanding: Allows researchers to gain insights into perceptions and experiences.
  • Flexibility: Researchers can adjust questions during data collection without strict structure.
  • Participant Voice: Enables participants to share their perspectives, often overlooked in quantitative studies.
  • Exploration of Complex Phenomena: Ideal for topics that are underexplored or existing theories are inadequate.
  • Rich Narrative Data: Provides thorough and deep understanding of "why" and "how" phenomena occur, rather than just "what".
