Accessibility Settings That May Help Students Navigate and Type
Additional settings that I would try with students would be the Large Mouse Cursor if students seem to lose where they are or have trouble locating the mouse. Along the same lines you can use the Highlight Text Caret to help students locate where they are typing, and also the Highlight Mouse Cursor.
It may be beneficial for teachers also to turn on the Highlight Mouse Cursor if they are demonstrating on their TVs how to do an activity.
