Monitoring, evaluation, research and learning (MERL) have changed significantly over the pastdecade due to advances in technology and data. This poster summarizes prominent and emergingevaluation practices and shares and discusses findings from a collaborative research effort thatexamined the state of the field for integrating technology into transdisciplinary monitoring,evaluation, research, and learning activities between 2014-2019. We discuss research onthree waves of tech present in the MERL space between 2014 and 2019: First wave: Tech forTraditional MERL (including mobile phones, satellites, and increasingly sophisticated databases) used to do ‘what we’ve always done’. Second wave: Big Data and data scienceapproaches in MERL. Third: Emerging approaches that use new sources and forms of data;different modalities of data collection, storage, and organization; and new techniques for dataprocessing and analysis. The poster shares and discusses recommendations for future research andpractice.
