The Student Detail button allows you to see the results for a particular student on an assignment.
Navigate to the Performance page of your Instructor Portal and click on the Student Detail button for an assignment. Then select the student from the drop-down list of students in the upper left-hand corner of the Student Performance Detail box. When the drop-down list opens, you can also start typing the student's first or last name into the search box to find them more easily.
The student's results will show in the box to the right of the drop-down list of names, and all of the questions will show below. Clicking on a specific question will show the correct answer for that question as well as the student's answer to the question. On the right-hand side of the window that opens, you can also see the date and time the student submitted their last answer and the number of times they submitted an answer for that question.
