The research question will suggest much about the methods required and the methods chosen must provide valid data for the subject studied.

 

Research methods need to be:

  • Appropriate for the setting;
  • Those that will answer the question;
  • Achievable in relation to the resources available (often most significantly in relation to time and finance);
  • Acceptable to participants, and fall within ethical codes for the field;
  • Appropriate to the researcher's skills (but also suit their style of working).
Types of research methods

In broad terms, research methodology may be:

  • Quantitative: data is in the form of numbers, eg the number of times a child shows a particular behaviour;
  • Qualitative: data is in the form of opinions and experiences, eg parent/carer perceptions of their son/daughter's transition process;
  • A mixture of both.

It is not necessary to use only one method; in fact researchers commonly use a combination. An inquiry may explore an issue (for example, 'what are the most challenging times of day to engage pupils in sedentary activities?') through a questionnaire, and then seek to explain it through follow-up interviews and observations.

The purpose of a research study will shape the methodology used, depending on whether the inquiry seeks to:

  • Explain (the causes/consequences/processes of something);
  • Predict (an outcome);
  • Explore (the experience of something);
  • Evaluate (the efficacy/efficiency/worth of something);
  • Describe (the nature of something, how something happens);
  • Test (a theory/assumption).
Calibrating the research question

The way a research question is posed will affect the methodology used to answer it. It is important to identify exactly what you are attempting to find out.

 

For example:

  • What causes a cup of water to overflow? (exploratory);
  • How much water causes a cup to overflow? (test);
  • What happens when a cup of water overflows? (explanation);
  • Is cup A more likely to overflow than cup B? (comparative evaluation).

All of the examples are studies of a cup of water overflowing. But the nature of the question suggests different methods to seek an answer.

Factors that can affect a research study

Even within a particular approach, a number of factors can still potentially affect the results of a research study.

 

An exploratory study of pupil attitudes towards exams may yield different results depending on whether a questionnaire, individual interviews or focus groups are used.

Q

Identify how you think that these different approaches may influence findings.

Mixing research methodologies: advantages

A mixture of qualitative and quantitative methodology can have a number of advantages, including:

  • If the results of both methods relate to the same issue, each can confirm the accuracy of the other (known as triangulation);
  • Quantitative data may provide the outcome ('what'), which can then be supported by qualitative data to explain the process ('why' and 'how');
  • Quantitative data often focuses on the researcher's concepts, which can be moderated by qualitative data giving others' perspectives;
  • Qualitative studies often need to be small scale, but additional quantitative data can support generalisation of findings.
Types of research

Research projects come in a multitude of types and sizes. When you read published

research, the researchers may describe their studies using descriptions such as experiment, quasi-experiment, case study, action research, ethnographic study or grounded theory, amongst others. What do these terms mean?

Whilst class-based or school-based inquiry tends to be of small scale, there is still a range of approaches that could be applicable in these settings.
