Calculate a grade

  • Updated

When calculating a grade you can choose to grade with a formula or to grade with a table.

  1. Click on your course or use the search bar in the Courses-section. 
  2. Click on your assignment or use the search bar. 
  3. Click on Settings in the menu at the top. 
  4. Click on Result options in the menu on the left.
  5. Click the drop-down button Grade calculation and choose Formula or Table.


Grading with a formula

  1. Fill in the grading formula. 
  2. Select the options Grade lower bound, Grade upper bound and Guess correction if desired.
  3. Click the drop-down button Rounding and choose the rounding method. 
  4. Fill in a passing grade. Standard, the formula is [1 + 9 * points / total], where points is the number of points obtained by a student and total is the total amount of points a student can obtain. Options that are available for this formula:
      • Math operators: + , - , * , / , ^
      • Logic functions: IF, AND, OR
      • Comparison operators: <, >, <=, >=, !=, =
      • Numeric functions: MIN, MAX, ROUND, ROUNDUP, ROUNDDOWN
    Using these operators and functions the following examples can be used:
      • Explanation: The following formula gives an answer of 1 if no points are gathered and increases as a polynomial.
        Code: 1 + 0.026984127 * points + 0.002050265 * points ^ 2
      • Explanation: If total number of points is lower than 45, use (points / 9) + 1 as marking formula. If total number of points is equal or larger than 45, use (4 * points / 45)+2 as marking formula.
        Code: IF(points < 45, (points / 9) + 1, (4 * points / 45)+2)
      • Explanation: The maximum of 0 and points minus 28 are compared and subsequently multiplied by 4 and divided by the total minus 28. Next, two things are added to this number: the minimum of 28 and points multiplied by 5 and divided by 28 and one (so a student will not get a mark lower than 1).
        Code: MAX(0, points - 28) * 4 / (total - 28) + MIN(28, points) * 5 / 28 + 1
  5. Click on Update. 

 

Grading with a table

You can use the grading table to convert the number of points to a mark. It is also possible to export the grading table from an assignment and import the grading table into another assignment. This can be useful if you want to share the same grading table between assignments.

  1. Click Add row and fill in a number of points, a grade and if desired a letter grade. 
  2. Click Save. 
  3. Repeat this for all scores.

error_outline Ans calculates a grade for closed questions and a grade for open questions. When these grades are calculated, they will be summed up by making use of the ratio closed open questions.

error_outline When a student gets a number of points in between two data points from the table, for example 22,0 points, the grade will be determined by the data point in the nearest vicinity. If the number of points is exactly in the middle it will be rounded down.
