Document Summary
Importance of evaluation: slow to develop in criminology despite its importance, evaluation has been slow to develop in criminology. Historically we have been able to come up with programs, but not evaluating them (whether they are successful or not). For example, the report on youth crime:280 programs, 500 million in funding, between 2002-2006. Majority of those studies were not evaluated, only 113 (40%) were subject to some kind of evaluation effort. How should we go about evaluating individual programs? (methodologies) Positivism: production of scientific knowledge the claim to be scientific in preventing crime. How should we go about evaluating individual programs? (methodologies: evaluation methodology: experimental and quasi-experimental design what"s most important is the methodology itself. Experimental designs: rcts as the gold standard the best experiments come from randomized control trials. This has a high degree of internal validity because it is random. Quasi-experimental designs there is an experimental and control group but no random assignment.
