Question 1: The Nature, Characteristics and Types of Research
Research is the engine behind knowledge creation, and every effective teacher benefits from
understanding what it truly is. The questions in this section examine research as a disciplined
activity, its essential qualities, its two dominant traditions, the sources from which problems
arise, and the qualities that make a research question worth pursuing.
1.1 Definition of Research
Research is a deliberate, structured process of asking questions about the world, collecting
evidence relevant to those questions, and using that evidence to build reliable understanding.
It goes well beyond ordinary curiosity or guesswork: where a curious person might wonder
whether a new teaching strategy improves comprehension, a researcher will design a study,
gather data systematically, and subject the findings to scrutiny before drawing conclusions.
In short, research is a way of knowing that insists on evidence and transparency at every
step.
What sets research apart from other forms of inquiry is its commitment to method. A re-
searcher does not simply observe and speculate; instead, each step from problem statement
to data collection to analysis follows a principled logic that others can examine, critique,
and replicate. This reproducibility is what allows knowledge to accumulate across time and
across different contexts. When a South African educator reads a study conducted in Kenya,
for example, the shared methodology is what makes the findings meaningful and transfer-
able.
Research is also a social enterprise. Findings are submitted to peer review, shared at con-
ferences, and published so that the wider community can test, extend, or challenge them
(Drozdz and Ladomery, 2024). This cycle of production and critique is precisely what elevates
research above personal opinion, making it the foundation of both professional practice and
policy.

Validity
Validity is the degree to which a research study actually measures or investigates what it
claims to investigate (Cohen, Manion and Morrison, 2008). A study on learner comprehen-
sion, for instance, would lack validity if its assessment tool measured only memorisation
rather than genuine understanding. Validity matters because findings built on a flawed mea-
surement base mislead practitioners. In educational research there are several dimensions
of validity, including content validity (whether the instrument covers the full scope of the
construct), internal validity (whether observed effects can genuinely be attributed to the vari-
able of interest), and external validity (whether findings can be transferred to other settings).
Threats to validity such as sampling bias, poorly designed instruments, and uncontrolled
variables can be reduced through careful planning (Cohen, Manion and Morrison, 2008).
Reliability
Reliability refers to the consistency and reproducibility of research findings: if the same study
were conducted again under the same conditions, it should yield substantially similar results
(Cohen, Manion and Morrison, 2008). In quantitative terms, a reliable measuring instrument
is one that produces stable scores across repeated administrations. In qualitative terms,
reliability is associated with dependability: detailed documentation of methods allows an
independent researcher to follow the same trail of decisions and arrive at comparable con-
clusions. Reliability and validity work together; a reliable instrument is not automatically valid,
but an invalid instrument cannot be reliable in any meaningful sense.
Key Distinction
Validity vs Reliability: Validity asks whether the research measures the right thing.
Reliability asks whether it measures that thing consistently. A thermometer that al-
ways reads 2 degrees too high is reliable but not valid; a broken thermometer that
occasionally gives the correct temperature is valid by chance but not reliable.
1.3 Qualitative vs Quantitative Research
Qualitative and quantitative research represent two distinct traditions, each with its own
philosophical assumptions, methods, and purposes. Understanding the difference helps a
researcher choose the approach most suited to the question being asked.
