  1. 1. Types of research and theoretical perspective of researchZuleima YañezYessica Serna
  2. 2. According to Kerlinger (1986), research can be conducted as exploratory, explanatory or descriptive.
  3. 3. Exploratory research is about putting one’s self deliberately in a place- again and again- where discovery is possible and broad, usually (but not always) nonspecialized interest can be pursued’’ Stebbins (2001)Exploratory research
  4. 4. Explanatory research has the aim of finding relationships among variables from theory based expectations whereas descriptive research aims to describe a situation or context. Malhotra & Grover (1998).Explanatory research
  5. 5. - According to Best and Kahn (2006), descriptive research is to find general attributes in the present condition.Itprovides systematic information about social phenomenaobserving and describing.Descriptive research
  6. 6. Theoretical perspective   “The philosophical stance informing the methodology  and thus providing a context for the process and grounding its logic and criteria methods and linking the  choice and use of methods to the desired outcomes”  (Crotty, 1998).
  7. 7. Although they are related, they are not the same.Each one is the base for the next one- Epistemology: theory of knowledge- Theoretical perspective: philosophical position- Methodology: strategies for conducting a research
  8. 8. Some types of theoretical perspectives- Positivism- Interpretivism- Critical inquiry
  9. 9. - The only authentic knowledge is scientific knowledge.- Researcher should be objective.- Quantitative data- Aim: offers explanations using scientific sciences. Objectivism (epistemology) Positivism (theoretical perspective) Survey research (methodology) Statistical analysis (method) (taken from Crotty, 1998)Positivism
  10. 10. Interpretivism- The methods of natural science are seen as inappropriate for study of people’s behavior.- The focus of interpretivism is not numbers; it is words.- Qualitative dataConstructionismInterpretivismEtnographyParticipantObservation (Crotty,1998)
  11. 11. Critical Inquiry- Related to interpretivism- This takes a critical look at society and tries to identify inequities and ways to remedy them.- Promotes democracy making differences in different contexts- The goal of critical inquiry is emancipation of the oppression.
