3ie How-To Videos

3ie’s How-To videos use a simple step-by-step approach for explaining theoretical concepts.

The How-To videos on impact evaluation draw from examples of impact evaluations to show you how to apply  technical concepts.

The videos in this series explore various topics related to designing, implementing and using impact evaluations. A short quiz at the end of each lecture will help you assess your understanding of the subject covered in the video.

We will be constantly updating our list of videos, so please keep visiting this page.

Video 4: How to use an evidence gap map

Speaker: Birte Snilstveit, senior evaluation specialist, 3ie 

Thousands of impact evaluation reports and systematic reviews on different development programmes are published every year. But this research lies scattered in journals, databases and websites. How can we then quickly consolidate what we know and don’t know on specific development themes or sectors?

In this video, 3ie’s Birte Snilstveit shows how the innovative 3ie evidence gap maps (EGMs) can address this challenge. EGMs consolidate what we know about what works in particular development sectors or thematic areas. 

They provide a visual display of completed and ongoing systematic reviews and impact evaluations in a sector or sub-sector, structured around a framework of interventions and outcomes. EGMs are a useful tool for development decision makers, researchers and donors looking for evidence to inform programme investments and identify where there is an urgent need for more research or rigorous evaluation. 

3ie’s interactive online platform allows users to explore the evidence included in a particular EGM, including links to each included study and review. To know more about evidence gap maps and how to conduct them, click here.

Video 3: How to manage a randomised evaluation

Speaker: Professor Howard White, Former Executive Director,3ie

Managing a randomised evaluation can involve addressing several challenges on the ground. In this video, Professor Howard White explores specific issues such as the need for securing the buy-in of key stakeholders, ensuring realistic timelines and overcoming opposition to randomisation.

Video 2: How to design a randomised evaluation

Speaker: Professor Howard White, Former Executive Director, 3ie

Randomised evaluations generate rigorous evidence on the impact of a programme. In this video, Professor Howard White explains the different designs of a randomised evaluation and shows how to choose the right design for an intervention.

Video 1: How to build a theory of change for an impact evaluation

Speaker: Professor Howard White, Former Executive Director, 3ie

A comprehensive theory of change is integral to designing a high quality and policy relevant impact evaluation. In this video, Professor Howard White uses the example of a school feeding programme to illustrate the steps involved in building a theory of change for an impact evaluation.
