Week 3 Discussion

Discussion: Theory, Research, and Evidence-Based Practice

As they explore the world around them, young children often
want to know the “why” and “how” of the things they observe. This is similar to
what researchers do when they approach a new problem. Researchers develop new
theories or build on old ones to explain the “why” of the world around them.
They use models and conceptual frameworks to help explain “how” the processes
and events they observe occur. Together, theories and models provide an
understanding of the world and allow researchers to explore it in meaningful
ways.

Virtually all research questions can benefit from the use of
an existing theory or model. Researchers should consider their research
questions and select the most suitable theory or model, which then serves as a
foundation for the research design. The selection of a theory or model is an
important part of the research process.

In this Discussion, you focus on the role of theory and
models in research and evidence-based practice.

To prepare:

Review the information in Chapter 6 of the course text.
Focus on the various conceptual theories and models that are currently used in
nursing research.

Select one of the theories or models described that is of
interest to you.

Using the Walden Library, search for and identify a research
article that uses the theory or model you selected.

Reflect on how the theory or model provides structure to the
research study described in the article.

Now, think about an issue in your practice area that you
would be interested in exploring through research.

Review this week’s media presentation and consider
strategies for locating and identifying a relevant theory or model for a
research study.

By Day 3

Post a summary of the article that you located and explain
how the theory or model that you selected was used in the research study.
Assess the value of basing research on an established theory or model.

Read a selection of your colleagues’ responses.

By Day 6

Respond to at least two of your colleagues on two different
days using one or more of the following approaches:

Ask a probing question, substantiated with additional
background information, and evidence.

Share an insight from having read your colleagues’ postings,
synthesizing the information to provide new perspectives.

Offer and support an alternative perspective using readings
from the classroom or from your own review of the literature in the Walden
Library.
