Open Forum
Open forum are designed to increase engagement and provide a modern alternative to standard Moodle forums.
Open forum reduce complexity and work like the modern messaging systems students use every day on the web and their mobile devices.
Unlike standard forums advanced forums are responsive, so users can read and post from their mobile or tablet. Advanced forums have been specifically designed to improve the usability and accessibility of Moodle forums.
Posting and replying are all done via ajax to save page loads, take less clicks and increase engagement, while maintaining the user's context in a discussion thread.
Open forums contain a number of additional features including the ability to see who has engaged in a discussion before you open it, a setting to show recent forum posts on the course page, subscribing to individual threads, private replies and an option to allow anonymous posting, post bookmarking, along with all the features standard Moodle forums have.
Open forums are design by Blackboard in partnership with The University of Montana.
