This articles covers Brightspace functionality that can accommodate negative marking (multiple-select type question).
Note: There is no option in Brightspace to get less than zero.
There are three possible grading options for multi-select questions:
- All or nothing - Users receive full points for the question only if they select all the correct answers and none of the incorrect answers. Users receive zero points for the entire question if they miss any correct answers or select any incorrect answers.
- Right minus wrong - Users receive points equal to the number of right answers they choose minus the number of incorrect answers they choose. Users can receive a minimum of zero on a question; they cannot receive a negative mark.
To calculate how much each answer is worth, the system takes the total number of points assigned to the question and divides it by the total number of answer choices.
For example, if a question is worth 10 points total and has 5 answer choices, each choice is worth 2 points (10/5=2). Correct answers are worth +2 points each and incorrect answers are worth -2 points each. If the user selects 3 correct answers and 2 incorrect answers, they would receive 2 points for each correct answer and lose 2 points for each incorrect answer, resulting in a total score of 2 points for the question [3(2)+2(-2)=2]. - Correct answers - Users receive points for each correct answer they select and for each incorrect answer they leave blank. Incorrect answers selected, and correct answers left blank, are not counted.
There are three possible grading options for short answer, multi-short answer, and fill in the blanks questions:
- Case Insensitive - Auto-grading searches for a matching character pattern in the answer text with or without letter case correctness.
- Case Sensitive - Auto-grading searches for a matching character pattern in the answer text that must have letter case correctness.
- Regular Expression - Auto-grading uses meta-characters to search for one or more matching strings in the answer text's character pattern. What you set as meta-character parameters helps determine letter case sensitivity.
There are three possible grading options for matching and ordering questions:
- Equally weighted - The total point value is divided equally among all possible correct matches. Users receive equally weighted points for each correct answer.
- All or nothing - Users receive full points for the question if they select all of the correct answers and none of the incorrect answers. Users receive zero points if they miss any correct answers or select any incorrect answers.
- Right minus wrong - Users receive points equal to the number of right answers they choose minus the number of incorrect answers they choose. To determine how much each answer is worth, the system takes the total number of points assigned to the question and divides it by the total number of answer choices. For example, if a question is worth 10 points and has 5 answer choices, each correct answer is worth 2 points, and each incorrect answer is worth - 2 points (10/5 = 2). If a user gives 3 correct answers and 2 incorrect answers, 2 is the total number of points received for the question [(3*2)+(2*-2)]. Users can receive a minimum of zero on a question; they cannot receive a negative mark.
