SUMMARY
Product: Coursera discussion boards
Objectives: To ascertain any usability or design problems within the Coursera discussion boards.
Methods: Heuristic analysis
Findings: I discovered 10 issues with the system. This included text that extended beyond the box it was typed into, a lack of feedback on several processes, slow uploads, and formatting problems.
Recommendations: Each of the problems identified has a solution, which includes allowing HTML formatting in post titles, creating more error messages when adding different elements to posts, including a progress bar when uploading images, and improving image editing, including cropping and an ability to add alt text for accessibility.
