Depicting the logic of three evaluation theories.

Here, we describe the development of logic models depicting three theories of evaluation practice: Practical Participatory (Cousins & Whitmore, 1998), Values-engaged (Greene, 2005a, 2005b), and Emergent Realist (Mark et al., 1998). We begin with a discussion of evaluation theory and the particular theories that were chosen for our analysis. We then outline the steps involved in constructing the models. The theoretical prescriptions and claims represented here follow a logic model template developed at the University Wisconsin-Extension (Taylor-Powell & Henert, 2008), which also closely aligns with Mark's (2008) framework for research on evaluation
