This report analyses the progresses made by Cambodia, Colombia, Mongolia and Uganda in the development and piloting of GCED tools. Based on the needs identified through the situational analyses carried out during Phase I, the four countries have developed tailored tools to mainstream GCED in their own context and piloted them during Phase II. Through an in-depth analysis of the tools as well as of their piloting processes, this report aims at understanding the extent to which GCED concepts are embedded and integrated into these tools and the way in which these tools contribute to the overall GCED teaching and learning practices in each context.
