RESEARCH TERMS

The many methods used all have names. In a brave attempt at getting my head around these I’ve started this list for the terms I stumble upon in H809 and related reading.

CRD : A cluster randomised design – by class as it is impractical to teach different things to the same group. (Torgerson and Torgerson 2001. p. 321)
CCT : Case Control Trial – A characteristic of this approach is that the two sets of schools may well be different in a number of aspects other than the intervention being tested, and this may affect the results. i.e. Schools needed to have been either chosen randomly or chosen because the had a similar intake and similar results.
Epistemological : the study or a theory of the nature and grounds of knowledge especially with reference to its limits and validity. (Merriam-Webster)
Ethnography : studying a particular culture by learning to live the life of its members (Hammersley & Atkinson, 1994).
Exploratory RCT: The explanatory trial design is probably the one with which most people are familiar.   (Torgerson and Torgerson 2001. p. 320)
Evidence based research: Randomized Control Trials  (RCT) – as Dr B. Price Kerfoot et al (2006-2012)
Interpretive paradigm: qualitative methods.
IRD. An individual randomised design – as with Spaced Education at Harvard Medical School under Dr. B. Price Kerfoot. (Torgerson and Torgerson 2001. p. 321)
Positivism: a belief in the application of a particular model of the methods of the natural sciences. In Wegerif: verification of hypotheses, numerical measurement, tests of statistical significance and experiments.
The pragmatic RCT : the environment in which the trial is conducted is kept as close to normal educational practice as possible, though the sample has to be far larger to detect smaller changes. (Torgerson and Torgerson 2001. p. 320)
Quantitative: of, relating to, or involving the measurement of quantity or amount. (Merriam-Webster) Coding schemes and publicly verifiable criteria to make categorisations. (Wegerif and Mercer.  1997. p. 271)
Qualitative: of, relating to, or involving quality or kind. (Merriam-Webster) Interpretative method (Torgerson and Torgerson, 2001) Interpretative analysis of transcribed speech = qualitative.  Are the techniques valid? The study of shared knowledge over time. Crook (1994) ‘Qualitative analysis can be effective for generating theories but not so effective for rigorously testing them (Hammersley, 1992).
