Knowing the difference between concepts, models and theories will help you understand research

and communicate intelligently with other professionals.

There are a number of ways to define concepts.

Essentially a concept is a description of an event, situation or experience.

Typically these descriptions of concepts are abstract and complex.

Some concepts are more understood than others.

It is important to define concepts so we can communicate.

For example, my husband and I have different views on what defines a garage and a shed.

Since we own properties with both our different definitions have caused some communication

issues.

When I talk about needing to clean the garage sometimes the wrong building gets cleaned.

Research studies should present a conceptual or theoretical framework in the introduction

portion of the article.

These frameworks tell you where the researcher is coming from and define the concepts under

study.

It helps to know how a researcher views the concepts under study so you can determine

if you or other studies you are looking at define these concepts in the same way.

That way you know if they are studying a shed or a garage.

Sometimes researchers will describe what is known about the concepts without a model or

theory.

In this case it is called a conceptual framework.

Other times they will present at specific model or theory to describe how the concepts

that they will be studying relate to one another.

However, before models and theories can be developed, concepts need to be defined.

There are specific methods to define concepts for research.

The methods chosen will depend on your beliefs about the nature of the concept.

If you believe concepts are concrete, measurable and do not change your approach will search

for the truth about the concepts.

Concepts that are defined in this way may be the variables under study in quantitative

research.

However, if you think that concepts are influenced by context, recognisable (but not measurable)

and dynamic your approach would be much different.

Concepts that are defined in this way would be more congruent as a framework for qualitative

research.

To find out more about how concepts are developed please visit the video on your screen.

Often research will examine the relationships between and among various concepts.

A framework that shows these relationships may be in the form of a model or a theory.

Models are usually developed based on qualitative research.

They demonstrate the researcher's interpretation of how concepts are related to one another.

You may find models in the findings section of some research articles.

Sometimes models are based on understandings that are not from specific research studies.

For example, the picture on this slide represents a model of my understanding of the difference

between concepts, models and theories.

Theories on the other hand are more tested than models.

They are systematic and are used to explain, predict, describe and prescribe phenomena.

They look a lot like models so sometimes people confuse these two terms.

Theories are tested and measured, most of the time with quantitative research, in order

to prove the relationships between concepts.

It takes a lot more than one research study to prove a theory.

Qualitative research can also be done to support theories.

The more research that supports a theory the better it is.

Remember, Concepts need to be defined in order to build a model or a theory.

Both models and theories show proposed relationships between concepts.

The difference between a model and a theory is the amount of "proof" that exists for them,

which stems from how they were developed.

Models are not considered proven.

Theories are considered proven and supported by multiple research studies.

That is why they are viewed as a more systematic representation of phenomena.
