Contamination in Trials of Educational Interventions

Educational trials

Hewitt C, Ramsay UEAC, Song F.
GSID: PM8e1wTK5-MJ
C Hewitt, A Howe, UEAC Ramsay, F Song, UEAJ Miles… - academia.edu

… Different combinations of the components of the contamination process favour either cluster or individual randomisation and should be considered when designing trials. Empirical evidence of the process of contamination during educational trials would be valuable. …

H Ainsworth, CE Hewitt, S Higgins… - Educational …, 2015 - Taylor & Francis

… In educational trials, the outcome of interest is usually a form of educational test. Often, several educational tests are given to assess outcome. It is important, however, that a single test is identified as the main outcome variable...
