Coggle is a collaborative, web-based application that only works online. You can use it offline after you’ve created your material in a PDF or image. It is an excellent tool to foster learners’ visual organization, improve their shared knowledge construction and create non-linear summarization. The task I’ve proposed below asks students to use Coggle to summarize information about global warming as the end of the unit, thereby they are asked to turn complex reading material into a structured visual map.
