Problem:
User mistakenly thinks they are in student mode because they see the 'Student View' text, in top right, and they don't understand that it is a button to click on, which would then bring them into student mode.
Improvement Suggested:
Add label to the 'Student View' mode so that it clearly describes what happens when you click the button.
Maybe something like "Switch Role to" (example used in other LMS Moodle) ?
