Both students and teachers are involved with marking Carousel quizzes.
First, immediately after answering a quiz, students go through and mark their answers. Exact matches and blank answers are auto-matched; for all other answers, students have to pick either NO, I WAS WRONG or YES, I'M CORRECT:
Then, once all students have marked a quiz, the teacher selects MARK QUIZ from the ACTIONS menu in their Teacher Dashboard:
WARNING: when you begin marking you lock the quiz, so make sure that everyone you want to respond has done so before you begin marking.
The teacher marking screen allows you to scroll quickly through each question to review students' self-marking. Where you disagree with the mark a student has assigned themselves you can change it using the CHANGE TO CORRECT and CHANGE TO INCORRECT buttons that show up for manually marked questions.
NOTE: you can use the slider in the top right of the screen to show only manually marked questions. This is useful for larger classes where you want to focus only on moderation and not seeing all students answers when you mark.
Once marking is completed you will be taken to an analysis screen where you can see your class's results at both question and topic level.
