5.13 Multiple Selection Questions

Description

Multiple Selection questions are similar to Multiple Choice questions. However, questions can have more than one correct answer. You can create as many choices as necessary. In Multiple Selection questions, the selections are permuted each time they appear. In non-permuting multiple selection questions, however, the selection order is static.

Grading

A multiple selection question is graded fully correct if the student selects all the correct answers (and no incorrect answers). The grader applies negative credit for selecting incorrect answers. The score is calculated using the following algorithm.

  1. Score +1 for each selected correct answer and -1 for each selected incorrect answer.
  1. Sum these scores. If this result is negative, then it is replaced by 0.
  1. Divide by the total number of correct answers.
  1. Multiply by the total points for the question defined during assignment creation.

That is, for a multiple selection question the score is given by the following formula:

with the exception that if the numerator is less than 0, it is set to 0.

For example, if the correct answers are (a) and (b), and the incorrect answers are (c) and (d), then selecting all four would score 0%, and selecting a, b, and c would score 50%.

If the multiple selection question is included as a part of a multipart or question designer question, the question score is multiplied by the question part weighting to determine the grade for the question. Question part weighting is set in the question definition.

Instructions

To create a Multiple Selection question:

  1. Select the Questions menu, then New Question. The Question Editor is displayed.
  1. On the Question Type screen,
  1. Select Multiple Selection.
  1. It is recommended that you enter a description in the Question Description text field. (The description is used to label the question in the topic. If excluded, the question type is used.)
  1. You can add Algorithms, Information Fields, Hints, or Feedback. For more details, see Adding and Editing Algorithms and Adding and Editing Information Fields, Hints, or Feedback.
  1. Click Finish.
  1. On the Question Details screen,
  1. In the text box, enter the question statement.
  1. In the Choices for the answers text fields, enter the possible choices and select the radio buttons corresponding to the correct answers. To add additional choice boxes, click Add Choices.
  1. Click Finish to place a copy of your question in the web site cache and preview your question.

Example 1: Creating a Simple Multiple Selection Question

To create a simple Multiple Selection question:

1. From the Class Homepage, click the Questions menu.

2. Click New Question.

3. In the Question Type list, click Multiple Selection.

4. Enter the following for Question Name: Fictitious forces.

5. Enter the following for Question Text: Which of the following are examples of fictitious forces?

6. Click Add Choice two times under Choices for the answer.

7. Enter the following five choices:

  • Centripetal force
  • Centrifugal force
  • Frictional force
