Say Hello to Research!
- What Research Is and What It Isn't
- The Role and Importance of Research
- An Introduction to Scientific Inquiry
- Different Types of Research
"A process through which new knowledge is discovered"
What Research Is...
Why is Research Important?
- Develops evidence base for practice
- Builds our profession knowledge base
- It is a compassionate, problem-solving, and
practical endeavor that follows professional ethics
- Likely to encounter numerous situations in your career when you'll use your research expertise
and wish you knew more of it
The Scientific Method
Types of research:
* based on the work of others
* can be replicated
* based on some logical rationale and tied to theory
* generates new questions or is cyclical in nature
* an apolitical activity that should be taken for the betterment of society
What It Isn't...
* plagiarizing other people's work
* falsifying data to prove a point
* misrepresenting information
* misleading participants
Asking the Question
"Raising a question or identifying a need that arises as the result of curiosity... Questions are informally stated and intended as as a source of discussion and stimulation about what direction the research topic should take."
For example, "What effects does using Facebook have on the development of friendships?"
Identifying the Important Factors
Select factors that: 1) Have not been investigated before 2) Will contribute to the understanding of the questions you are asking 3) Are available to investigate 4) Hold some interest for you personally or professionally 5) Lead to another question
- Age - Gender - Ethnicity - Level of education
- Access to types of Social Media
- Number of self-identified close friends
- Parental attitude toward social media
- Family configuration
- Family Communication patterns
Formulating a Hypothesis
"A hypothesis results when the questions are transformed into statements that express the relationship between variables such as "if...then" statement."
For example, "Adolescents who use Facebook as their primary means of maintaining social contact have fewer close friends."
Collecting Relevant Information
This will confirm or refute the hypothesis.
For example, "The number of friends an adolescent might have. And the quality of those relationships."
Testing the Hypothesis
"An important point to remember is that you set out to TEST the hypothesis, not PROVE them."
"The job of all the tools that researchers have at their disposal is to help separate the effects of the factors being studied from other unrelated factors"
Working with the Hypothesis
Examine the results, which will confirm or refute the hypothesis.
For example, "Involvement in social media has no impact on social skills or social relationships."
Reconsidering the Theory
Theory: "A set of statements that predict things that will occur in the future and explain things that have occurred in the past"
For example, "Social learning theory which places special importance on the role of modeling"
Asking New Questions
"It might be a simple variation on a theme (Do males use social media in a different way than females?) or a refinement of the original question. "
Marcy Higareda, MSW
Nonexperimental Research: Research in which no manipulation of variables is involved and no cause-and-effect relationship is studied
Experimental Research: Research that examines cause-and-effect relationships through the use of control and treatment groups.
