2 Campbell ..a society that would use social science methods andevaluation techniques to vigorously try out possiblesolutions to recurrent problems and would make hard-headed, multidimensional evaluations of outcomes, andwhen the evaluation of one reform showed it to have beenineffective or harmful, would move on and try otheralternatives (Campbell, 1999a:9). A family of research methods which seeks tosystematically investigate the effectiveness of ways that improve socialconditions (Rossi, Freeman and Lipsey, 1999:20)What is evaluation ?
3 Types of evaluation Impact (or summative) evaluationsDoes the policy (programme, intervention)work? How large is the likely effect size? Process (or formative) evaluation How,why, and under what conditions does thepolicy (programme, intervention) work? What is the Policy Question? Effectiveness of What? Intervention effectiveness - what works? Resource effectiveness - at what cost/benefit? Likely diversity of effectiveness across different groups what works for whom and when? Implementation effectiveness - how it works? Experiential effectiveness - public s views of policy4 Evidencefor PolicyTheoriesof ChangeHow is the policy supposed to work?
