World café (conversation)
A world café is a structured conversational process for knowledge sharing in which groups of people discuss a topic at several small tables like those in a café. Some degree of formality may be retained to make sure that everyone gets a chance to speak. Although pre-defined questions have been agreed upon at the beginning, outcomes or solutions are not decided in advance. The assumption is that collective discussion can shift people's conceptions and encourage collective action. Events need to have at least twelve participants, but there is no upper limit. For example, in Israel in 2011 an event called 1000 Tables was hosted in several cities on a single day as part of a series of social justice protests held around that time, and around a thousand people participated. Knowledge café 
A knowledge café, as developed by David Gurteen, has small tables, and a single open ended-question for all of the groups to discuss. The aim is to maximise time spent in conversation, so that time spent with any one person presenting is minimised. Discussion at each table is open and there is no formal attempt to capture what is said—the value is in the conversation itself. Modified world café 
Modified world café is a variant developed in 2019 and structured in two rounds which have the same length and an equal number of tables. Each group is provided with a goal to work on and each round is ended by plenary presentation. After the intermediate presentation, all members of each group except one (called the "host") are asked to move their seats to a new table and start a new round of discussion that is concluded by a final plenary presentation. Application in Japanese clinical clerkship and postgraduate (residency) clinical teaching showed a relevant increase of the perceived usefulness and consent in respect of the product of the discussion groups.
