together with a reflection on the use of these in metasurveys and metaevaluations.

      Chapter 9 is the first substantial case study chapter and examines the rise and fall of the Bernsteinian sociolinguistic research programme (Bernstein 1973a, 1973b). This research programme has been chosen to illustrate the ambitions of EER in a time of considerable optimism about its potential to change educational practice, its relatively innovative approach to empirical research and the way in which it appeared to tie together various factors involved in educational achievement in a convincing looking explanatory framework. At the same time, the weaknesses of the programme, which eventually led to its abandonment, will be looked at. The included: inadequate conceptualisation of the key organising concept of linguistic code; ignoring of factors such as acquaintance with literacy; inappropriate intervention methods of data collection and a weak empirical basis for large-scale generalisations. The case also illustrates how a research programme which is getting into difficulties tries to solve its problems through semantic redefinition rather than data collection, following predictions made by Lakatos. Some key lessons about future research in the area are drawn.

      Chapter 11 takes up the case of School Effectiveness Research (SER). From the 1970s onwards, dissatisfaction with the paradigmatic view that ‘Education cannot compensate for Society’ grew and the search was on for ways of distinguishing effective from ineffective schools. I will examine the choices available for investigating this issue and explain those that were eventually made in the dominant research programme in this area. Key methodological decisions and conceptual approaches are examined and the course of SER and its achievements and limitations are described and discussed. A number of critical issues are identified. These include the definition of ‘school effectiveness’ adopted; the limitations of the regression-based methods for measuring effectiveness, including measurement error, the problem of missing values and the problem of unstable results. Problems to do with generalisation of findings will also be broached. These include the difficulties of putting SER research into viable school improvement strategies, the interpretation of the regression-based findings for the identification of features of effective schools and the relativistic nature of the data. The chapter will include an estimation of the achievements as well as the setbacks of the SER programme.

      Chapter 13 takes us to an issue which has always plagued EER and its application. This issue, which involves the uncritical and enthusiastic acceptance of the deliverances of EER, usually followed by disappointment and the entry of a new challenger in the lists, I call educational faddism. Educational faddism is the shared responsibility of governments and policymakers, teachers and educational researchers. I will describe the pressures which make educational faddism based on EER so irresistible and also show how it has also undermined faith in EER. Ironically, this point applies to recent attempts to transcend it through the use of metasurveys which seem to provide clear deliverance of the implications of any such research. Failure to attend to Mackie’s point about causal fields, described in Chapter 8, exacerbates the difficulties in making productive use of EER in policy initiatives. However, it is also the case that failure to attend to basic canons of probity in EER can be avoided and a lot of consequent mistakes avoided if policymakers and researchers are self-disciplined enough to do so.

      Hermeneutics can be used judiciously with a more synchronously inclined form of conceptual analysis (for example in the study of conceptual variations in know-how concepts – Chapter 10) and a reflective element in the philosophical analysis of educational issues is always required to ensure that inquiries into the requirements of particular conceptions of education do not masquerade as categorial investigations. It can be particularly difficult for analysts personally committed to a particular conception of education to refrain from importing elements of their own preferred conception into categorial assertions.

      Chapter 15 takes an extended look at the relevance of the discussion of EER to teachers’ own practice. It has been argued that it is impossible, if not incoherent to ignore the findings of EER. It has also been pointed out that it is difficult to draw practical conclusions from such findings. What does this mean for teachers? It will be argued that teachers do need to be able to distinguish between good and poor quality research on the one hand and relevant and less relevant research on the
