How partial credit works in LearnJCU

Enabling the Allow Partial Credit option for a question allows a proportion of the total possible marks for a question to be awarded if the answer is judged to be partially correct.

All manually-graded questions can be assigned partial credit. It is up to the person marking the question to judge how many points to award.

The following automatically-graded questions also allow partial credit: Calculated Formula, Fill in Multiple Blanks, Jumbled Sentence, Matching, Multiple Answer, Multiple Choice, Opinion Scale/Likert, Ordering, Quiz Bowl.

Example: Partial credit calculation for a multiple answer question

Rules for determining partial credit

  1. Total score for the question is equally divided among the number of correct answers, ie. Equal part marks

  2. An equal part mark is awarded for each correct answer

  3. An equal part mark is deducted for each incorrect answer (so a student will be deducted the same value for an incorrect answer as they are credited for a correct answer)

  4. No marks are awarded if no answer is given.

Example 1

Question: The separation of powers...

  1. means that the three arms of government should be independent from each other and exercise their powers in a mutually exclusive manner

  2. is a feature of the Westminster system

  3. only operates in the Commonwealth not the States

  4. was introduced by William the Conqueror

  5. refers to the separate legislative powers held by Commonwealth and States

Correct Answer: a and b

Given Answer: b and d

Possible points: 5

There are 5 possible answers, 2 of which are correct. So, an equal part mark is 2.5. (ie. 5 / 2). The two correct answers are a and b. A student answered b and d, so scores one part mark for her correct answer (d) and loses one part mark for her incorrect answer (c).

Partial credit calculation: 2.5 – 2.5 = 0.

Example 2

Question: The Australian Constitution...

  1. was enacted by the UK Parliament

  2. embodies the doctrine of separation of powers because it provides for the establishment of Australia's three arms of government and outlines the scope of their powers

  3. is a source of validity for the laws enacted by the Commonwealth Parliament

  4. contains a clause (section 109) which helps resolve inconsistencies between the laws of two or more Australian States

  5. was enacted by the new Commonwealth of Australia Parliament in 1901

Correct Answer: a, b, c

Given Answer: a, b, c, d

Possible points: 5

There are 5 possible answers, 3 of which are correct. So, an equal part mark is 1. 67. (ie. 5 / 3). The three correct answers are a, b and c. A student answered a, b, c and d, so scores three part marks for his correct answers (a, b, c) and loses one part mark for his incorrect answer (d).

Partial credit calculation: 1.67 +1.67 +1.67 –1.67 = 3.33
