Using Scratch-Off Questions

Scratch-off Mode

In FeedbackFruits, a scratch-off type question is an interactive multiple-choice question where students select an answer and receive immediate feedback. When Scratch-off questions mode is enabled, multiple choice questions reveal only whether the selected answers are correct after submitting. This is also known as the Immediate Feedback Assessment Technique (IF-AT), which is fundamental to the Team Based Learning pedagogy.

If the selected answer was incorrect, this is revealed to the student, but the other answers remain veiled. The student can retry by selecting another answer, but has lost half of the points. When correct they can still save the remaining 50% of the score that's available. But if they miss again, they lose again half of the available score. This halving of the reward continues until the student has exhausted the options. For the last remaining answer no grade is rewarded. This grading mode is known as decremental scoring, and is integral to scratch-off questions.
