An app for evolving conversations
Talkwall is based on research about a specific kind of conversation or dialogue. These dialogues take place in learning situations, evolve for participants and are often lead by teachers.
Design principles for Talkwall
Microblogging: Messages written by students are limited to 140 characters. This means students cannot copy text directly from a source and must summarize. Once concepts are identified, they can marked with a hashtag, and become tags in the Talkwall. Tags can be used to filter messages.
Visualization: Going from messages in a conversation to organizing messages is an important step. In Talkwall, messages can be dragged onto the wall and organized in relation to each other.
Shared screens: Teachers, or whoever sets up a Talkwall, can easily share visualizations of the messages with students using a projector or big screen.
Talkwall was developed as a result of education research in the field and collaboration with teachers. Developers used an iterative design process, where each new version was tried out in the classroom, user experiences collected, and new featured added. An early version of Talkwall was developed for the TWEAK project.
