It’s sometimes unclear whether assignments have been successfully posted to student drop-boxes. Instructors are not consistent about assignment deadlines, with some permitting late assignments and some forbidding them. The size limit for submitted assignments sometimes makes it difficult to submit program files using databases or images. Team assignments are now permitted, but it’s confusing whether team members can overwrite each other’s submissions. Some instructors post assignments on the system, but most still provide hard copies in class. Having assignment grades posted on the system as soon as they’re ready is convenient, as long as it’s secure. Calendar arrangement of due dates is confusing, allowing instructor to list assignments above their due dates. Instructor may toggle descriptions on (making interface crowded) and off (hiding info from users). Many icons are provided, but they’re small, often obscure, and have long delays before tool-tips appear. Grade screens use extremely small font, allowing display of large classes without much scrolling, but damaging readability. Student profiles list first and most recent access times, but do not log all uploads and downloads. Students may use drop-box to submit early assignments, but must notify instructor by of having done so. Instructors may input settings so graders are notified when students submit assignments. Separate logins are not required when students shift from one course’s drop-box to another’s. Student may access schedule of all events (including due dates) occurring in the next two weeks for all of student’s classes. Instructor may post announcements to individual students, project teams, and entire classes. System automatically logs out students and instructors after fifteen minutes of inactivity. Calendar of upcoming assignments may be displayed for one class or for all classes. Most pages include help documents explaining the purpose and usage of the fields on those pages. Students report increased levels of interrupted service when uploading assignment files from off campus. Users may post profiles that include a photo, a list of interests, and contact information. Instructors may retrieve logs of every participant’s access to their account for a particular class. SUBMISSIONS CONSISTENCYSECURITYUSABILITYNOTIFICATIONS
