摘要	A logic model is a systematic, visual representation of how a program is understood to work: it lays out the logical relationships among the resources invested (inputs), the things done (activities), the products of those activities (outputs), and the changes expected to follow (outcomes and impact). Logic model analysis is the practice of building, examining and using these models to plan programs, guide implementation, and structure evaluation. Popularised by the United Way and codified in the W.K. Kellogg Foundation's widely used 2004 Logic Model Development Guide, it has become the workhorse framework of program planning and evaluation.	Theory of change evaluation is a theory-based approach that evaluates a program against an explicit map of how and why it is expected to produce its intended outcomes. Rooted in Carol Weiss's work on theory-based evaluation and the Aspen Institute's community-initiatives projects of the 1990s, it requires evaluators to articulate the full causal pathway from activities through short- and intermediate-term outcomes to a long-term goal, make the underlying assumptions explicit, and then collect evidence to test whether each link in that chain holds in practice. The theory of change serves simultaneously as a planning tool and as the framework against which the program's progress and plausibility are judged.
