Abstract
An online discussion board called the Collab2learn Discussion Board (DB)
enables participants’ to learn collaboratively within groups. Groups are limited in using
different feedback formats; either textual or iconic. 57 participants from an institute of
higher learning tested Collab2learn DB usability. System Usability Scale (SUS) was used to
measure Collab2learn DB usability. Its average scores were compared between two
different feedback formats (textual and iconic). Results indicated Collab2learn DB is a
usable online discussion board however further improvements need to be done especially in
the prototype’s functionalities integration and consistency.
