Quiz tips and tricks
Regrade is found on the Results Tab of a Quiz. Regrade is used to force Moodle to recalculate points awarded for correct and incorrect responses to quiz questions after the quiz has been taken by students. It is useful in making corrections to points awarded due to teacher error or because of unexpected correct responses in short answer questions.
The most efficient way to use regrade would start with Item Analysis (Overview tab of a Quiz). A teacher can view the item analysis page and look for anomalies in the numbers of students that chose the correct and incorrect responses. These anomalies can draw attention to any mistakes made during question creation. For example, during the creation of a question, a teacher may inadvertently tag a wrong answer as a correct one or make a typing error while entering the correct answer for short answer questions.
The analysis can also point out alternate, yet correct, answers to short answer questions that were not included when it was created. When viewing the analysis page, teachers can pinpoint other correct responses made by students.
Questions needing correction or additions can be edited by clicking on the question ID number on the item analysis page. Teachers can even look for common misspellings in the correct response and, depending on his or her policy, can award partial or full credit to students for the misspelled response.
Once analysis is complete, and all questions needing editing have been edited, clicking on regrade will update the scores for all students that the edits affect. This method ensures fairness in scoring on the current quiz and future quizzes while it minimizes the need for “Make comment or override grade” in the individual overview of a students attempt.
