Calculated questions are numerical questions but based on a formula, with the numbers used selected randomly from a set when the quiz is taken. They ensure different students doing the same question will be asked different calculated variations, helping reduce cheating.

Adding a Calculated question

General

Category drop-list: A category other than the default one can be selected from the Save in category drop list if you untick the "Use this category" check-box. For example, if you have sub-categories for each element you could choose the element that the question was mapped to. (See notes on "Creating Categories" for more information).

Question name*: Enter the title of the question. Question names are only seen by course developers (not students). You could enter your element and PC mapping in the name to make it easy to locate questions related to specific performance criteria.

Question text*: Enter the question text here, including the formula fields.
See Example calculated question for a step-by-step example.

Default mark*: By default, each question is assigned 1 point.

General Feedback: You can provide general feedback in this area to give students information. You may also provide a link to more information they can use if they do not understand the questions.

Answers: The answers are given in the form of a formula. In the pictured example, the student must answer the question by multiplying the base value of the rectangle by the height value. See Example calculated question for more details.

Grade: A grade is assigned for each answer to the question. If there is only a single correct value, then the answer is graded 100%. If you provide multiple correct formula you can specify a weighting for the preferred method, e.g. 60% and 40% where the 60% answer is the preferred formula to use.

Tolerance: A tolerance may be set where complex calculations are involved. This will give students a range of accepted values above or below the intended answer that the question will accept as correct. The types of tolerances can be set to: Relative, Nominal and Geometric.

Feedback: Feedback may be provided that will appear for correct answers.

Unit Handling:  You can set whether or not the student needs to add a unit to the numerical value in order to receive a grade.

Settings for multiple tries

Penalty*: A penalty may be applied for each incorrect try if you are using either Adaptive mode or Interactive with multiple tries in the quiz. If you are using either of these and want the student to be able to achieve 100% you will need to set to 0%.

Settings for multiple tries

NOTE: Adding a penalty to a VET quiz would prevent a student that made an error from ever being able to reach "100%". For this reason penalties are not usually used with VET assessment quizzes.

Once you have completed your question, click on Save changes.
