Week 2 Philosophical foundations, language and thinking processes Flashcards
(33 cards)
Ontology
The study of what exists, and how we understand and categorise the things that exist. What we think is real and exists. What is reality?
Epistemology
How we come to have knowledge of the world, and the rules for knowing. What are the ways of discovering what exists?
Selecting a research tradition
How do researchers decide on which tradition to use? (PPLP)
- Purpose of the research
- Preference for knowing
- Level of knowledge development
- Practical considerations
Methodology:
Overall framework related to the associated paradigm
Methods
Techniques used to collect and analyse data
Tools
The devices used to collect data
Methodological design:
The plan for conducting the research
Experimental type designs
- The research design is the plan that specifies and structures the action processes used to answer the research question
- The purpose of the design is to control or restrict the extraneous influences on the study
- This allows the researcher a degree of certainty that the observations or outcomes of the experimental type research are not random but actually reflect the reality that is being examined
Sequence of experimental type research
- Problem statement - Theory - Research question - Design - Data collection - Data analysis - Reporting
Concepts:
Words or ideas that symbolically
represent observations and experiences
Conceptual definition:
Stipulates the meaning of concepts or constructs in words, the relationship between different concepts or constructs, and the theoretical framework that the concepts or constructs can be seen in
Operational definition:
Stipulates how the concepts in the research are observed or experienced which in experimental type research means specification of how the construct will be measured
Independent Variable:
Is the cause. Its value is independent of other variables in the research
Dependent Variable:
is the effect. Its value depends on changes in the independent variable Intervening (extraneous or confounding)
Variable
Is any variable that the research is not investigating that can potentially affect the outcomes of your research study
Hypothesis
is a statement that can be tested • indicates what the researcher expects to find • can be directional
Positive hypothesis
(both variables increase or decrease) e.g. as temperature increases research exam scores increase
Inverse hypothesis
(one variable increases and one variable decreases) e.g. as temperature increases research exam scores decrease
Bias
Unintended or unavoidable effects on the study outcomes
• When bias is present and not accounted for the researcher may draw incorrect conclusions from the research
Systematic error (or bias) can occur in three different areas of the research design:
- the way participants are selected
- how variables are measured
- the method of data analysis
Plan of the design-manipulation
- Manipulation is the action process of altering the independent variable so the effect of its presence, absence or variation can be observed and measured
- Manipulation is usually seen in experimental type designs investigating the effects of an intervention (independent variable) on a defined set of outcomes (dependent variable)
Plan of the design-control
- Control is a set of action processes that direct or manipulate factors to achieve an outcome \
- Control in experimental type designs is used to minimize the extraneous influences (intervening variables or bias) on the dependent variable
Some ways experimental type designs use control are:
- using established inclusion and exclusion criteria for participants
- using valid and reliable measurement tools
- training research assistants in how to collect data
- the use of a control group -random assignment
Validity
Validity refers to the extent to which your study answers the research question
