  3. Designs • Experimental (Quasi-experimental) • Survey (Descriptive, Analytical) • Case Study • Ethnography • Phenomenology • Mixed methods

  4. Experimental • Purpose: Causality, Theory Testing • Are set up so that causality may be examined • Intervention: the researcher does something to at least some of the participants in the research • Control: the experimenter introduces one or more controls over the experimental situation • Randomisation: the experimenter assigns participants to different groups on a random basis.

  5. Experimental Subjects

  6. Experimental x y Random

  7. Experimental Measure T1 x y

  8. Experimental Intervention X x y

  9. Experimental Measure T2 X x x y y

  10. Quasi-experimental intervention X1 (30) X2 (30) School A Y2 (30) Y1 (30) School B

  11. Quasi-experimental intervention X1 (30) X2 (30) School A

  12. Survey-descriptive • Are designed to gain more information about a particular characteristic within a particular field of study • describe or establish categories • How many? or how often?

  13. Survey - Analytical • specifically set up to explore the relationship and associations between particular concepts / variables • Less orientated towards representativeness and more towards finding explanations • Focus on theory building or testing • Asks: ‘why’ and ‘what goes with what’ ?

  14. Survey - Analytical • Correlation • the basic purpose of this form of study is to determine the relationship between variables • is bullying related to achievement? bullying achievement

  15. Survey - Analytical • Is self esteem related to achievement • However causality cannot be established with this design selfesteem achievement

  16. Case Study • Purpose: Intensive investigation of a case within its real life context using multiple sources of evidence. • An organisation, school, individual, committee • Holistic understanding of a set of issues in a particular environment and context • Yin, R. (1994). Case Study research: Designs and Methods. (2nd ed.) Beverly Hills, Ca: Sage. • Yin, R. (2004). The Case Study Anthology. Thousand Oaks, CA: Sage.

  17. Case Study Methods • Questionnaires • Documents • Observations • Interviews • Focus groups

  18. Phenomenology • Purpose: Is to interpret and represent the way that people understand specific concepts • A focus on perceptions • Aim is to get in-depth understandings • Descriptive • Patton, M. (2002). Qualitative Research and Evaluation Methods. California, Sage.

  19. Phenomenology methods • Interviews • Semi-structured • Unstructured • Often involving 2nd/3rd interviews

  20. Ethnography • Purpose: Is to interpret and represent the social world in the way that your participants interpret it • traditionally associated with anthropology • usually involves immersing yourself in a particular context or culture • Patton, M. (2002). Qualitative Research and Evaluation Methods. California, Sage.

  21. Ethnographic methods • Interviews • Observation • Group Interviews

  22. Mixed Method Designs • You can mix your methods but not your assumptions / philosophy! • Pick your MAIN method and use the other methods to SUPPORT it

  23. Mixed Methods? Positivist – Quantitative Research Representative and Predictive Interpretist – Qualitative Research Depth and Understanding

  24. Sequential Designs • stages feed into each other • normally there is a main stage QUANT qual QUAL quant QUAL quant

  25. Concurrent Designs • stages occur simultaneously • have equal importance, but different foci • requests from each stage ‘compared’ QUANT results QUAL results
