FORMULATING THE PROBLEM
    Experimental Designs
    Quasi-Experimental Designs
    Operationalizing Success/Failure
    Qualitative Evaluations

    Evaluation research follows the logic of experimentation: we measure the starting condition, we launch an intervention intended to change the starting condition, and we measure conditions afterward.

    The discussion of experimental designs in Chapter 8, then, is relevant to evaluation research, and this section will review some of those designs with an eye to how they could be used in evaluation research.

    We'll also see that evaluation research need not always be quantitative, and we'll look at some qualitative methods that can be used.
