Cumulative brainstorming – this collaborative activity promotes deep learning by encouraging students to build on or critique each other’s ideas. The students work in group. Each group get a different topic, question or problem and has about five minutes to write down some ideas about the topic. After that the group get another topic, continue and accumulate the ideas that previous group has already started.
In this setting the groups are working separately but the ideas have to be accessible immediately to other groups. It is recommendable to use groups (e.g. breakout rooms or channels) and one collaborative space – whiteboard (for instance MS Teams), padlet, miro or similar with distinguishable areas of topics.
