This means they either use simple but inappropriate techniques that they can understand or they use complex appropriate techniques that they do not understand. The use of simple techniques leads to the criticism that these approaches are too reductionist to ever capture social reality in any meaningful way... Hilary Browne Wed, 31 October 2007 16:00 +0000 http://www.cmm.bristol.ac.uk/research/Lemma/index.shtml#contextual Multillevel contextual studies look at the effects of group-level (L2; eg, schools, classes, families, neighborhoods, etc) characteristics on individual-level (L1) measures Hilary Browne Wed, 31 October 2007 16:00 +0000 http://www.cmm.bristol.ac.uk/research/Lemma/index.shtml#modelimpact Value added analyses of school performance typically assign students to the school where they take the outcome test or examination. A particular problem with this is that this ignores the fact that many pupils move school between the time that they take the prior test or examination and the time that they take the outcome test. For example, for GCSE outcome in England where an 11-year old test score is used to adjust for prior achievement, up to 40% may have changed school in some areas. Ignoring this will tend to reduce the amount of variation estimated at the school level and distort inferences in terms of school effectiveness. The paper demonstrates this effect, using multiple membership models with data from English Local Authorities provided by the National Pupil database. It also shows that rank orderings of schools are almost unaffected when the proper analysis is carried out.
