[6] The proposed interactive e-learning community (iELC) is a platform that engages physics students in online and classroom learning tasks.
[14] The discussion trees in D-Agree, inspired by issue-based information system, contain a combination of four types of elements: issues, ideas, pros, and cons.
For instance voting, targeted notifications, user levels, gamification, subscriptions, bots, discussion requirements, structurization, layout, sorting, linking, feedback-mechanisms, reputation-features, demand-signaling features, requesting-features, visual highlighting, separation, curation, tools for real-time collaboration, tools for mobilization of humans and resources, standardization, data-processing, segmentation, summarization, moderation, time-intervals, categorization/tagging, rules and indexing can be leveraged in synergy to improve the platform.
Research demonstrates that such spaces can even undermine deliberative participation when they allow hostile, superficial and misinformed content to dominate the conversation (see also: Internet troll, shitposting).
[4] Online citizen communication has been studied for an evaluations of how deliberative their content is and how selective perception and ideological fragmentation play a role in them (see also: filter bubble).
One sub-branch of online deliberation research is dedicated to the development of new platforms that "facilitate deliberative experiences that surpass currently available options".
