Learning What Works

Public Policy & Politics

Course Overview

At its heart, policymaking is about problem-solving. It is about identifying real challenges in the wider world and creating responses to those problems. Some interventions designed and implemented by policymakers have resulted in significant benefits: policies have both improved and saved lives, preserved the environment, helped the economy to grow, and made people safer.

Course features

But not all interventions work: some simply fail, either in their design or implementation phases. This results in lost resources and time and means the problem continues. Sometimes, despite the best of intentions, policies can make things worse. Interventions that should logically work, occasionally bring about exactly the outcome the policy is designed to avoid. These policies not only waste resources needed to build and run them; they also harm people, communities, and societies.

For this reason, evaluation is critical. Understanding "what works" is essential if we are to establish whether a policy is bringing about the outcomes we want. Unfortunately, establishing "what works" is not a simple task. The very questions we ask are informed by epistemic and ontological assumptions. If we aren’t aware of these assumptions, we risk performing unnecessarily narrow evaluations that deprive policymakers of what they need to know. Furthermore, there are a host of potential pitfalls, methodological mistakes, and design issues that need to be recognised and mitigated if we are to know whether our solutions to problems are really solving those problems.

In this module, we will explore the role of evaluation in policymaking and provide an overview of the tools of evaluation. You will have the opportunity to critique existing evaluations as well as design an evaluation of your own.

Course content

Week 1: Introduction to evaluation

Without undertaking evaluation, we won’t know if we’re wasting resources on interventions that are ineffective, or even interventions that hinder us in meeting our goals. This week will centre around outlining the purpose of evaluation and how best to articulate the goal of our evaluation.

Week 2: How do we know?

One of the biggest challenges in using evaluation to determine what works is to design the research so that we are convinced that a causal interpretation is warranted. The focus of this week will on how to determine what works.

Week 3: Putting it all together: practicing evaluation

The aim of this final week is to practice applying what we’ve learned so far. We will look at several studies as a practice to thinking through evaluation design.

Learning outcomes

Upon completion of this module, students will be able to:

  • Analyse the dynamics of the political and epistemic relationship between policymakers, practitioners, citizens, and researchers.
  • Assess the claims that can be made based on different types of evidence and evaluation.
  • Appraise the quality and rigour of an evaluation.
  • Analyse evidence, identify gaps in that evidence, and select appropriate tools to fill such gaps.
