Adjusting the Scoring Weight of Question Responses

MINI LESSONS ›› Quiz Related Topics ››

MINI LESSON

When ToolBook calculates the score of a question, the process is more complex than just generating 0 points for a wrong response and 1 point for a correct response. The reason it is more complex is so that you can provide a point value for a partially correct response.


The following examples will demonstrate how weighting works within a question.


Note that for each example below:



Multiple Choice (multiple responses, with only 1 correct)

This is the default configuration for a Multiple Choice question object in the catalog. It allows you to display several possible answers and is configured so that only 1 of them is correct and only one is allowed to be chosen by the learner.


This configuration starts by ensuring that the Multiple choice/multiple correct option on the Answers tab is not checked. This setting being unchecked will prevent the user from choosing multiple answers.


 


The Scoring tab is where you will find the ability to alter the scoring weight of each response.


As seen below, with this question set to Automatic scoring, the correct response is worth 100% of the Highest Possible Score, and the incorrect responses are worth 0% of the Highest Possible Score.


 


 


With this configuration a correct response will result in a value of 1 point for this question and an incorrect response will result in a value of 0.

TURNING OFF THE AUTOMATIC CHECKBOX

If you turn off the Automatic checkbox, you are free to manually set the weight value for any of the possible answers.


For example if Choice #2 is somewhat correct, you might decide to set the weight for this response at 50%, which would generate a score of .5 points if chosen by the learner.


Multiple choice (multiple responses, with multiple correct)

This configuration for a Multiple Choice question allows you to display several possible answers and is configured so that more than 1 can be correct, and allows the learner to choose more than one answer.


This configuration starts by ensuring that the Multiple choice/multiple correct option on the Answers tab is checked. This setting being checked will allow the user to choose multiple answers.


 


The Scoring tab is where you will find the ability to alter the scoring weight of each response.


As seen below, with this question set to Automatic scoring, the correct response is worth 50% of the Highest Possible Score, and the incorrect responses are worth -50% of the Highest Possible Score.


Why 50%?


This values comes from the full value of 100% divided by the number of correct responses. So 100 divided by 2 = 50.


 


 


Below is a grid showing the score for each possible answer combination to this question, assuming the Automatic checkbox is turned on:


Choice #1    Choice #2    Choice #3    TOTAL PERCENTAGE

---------    ---------    ---------    ----------------

50%                                    50% or .5 points

50%          50%                       100% or 1 point

50%                       -50%         0% or 0 points

50%          50%          -50%         50% or .5 points

             50%                       50% or .5 points

             50%          -50%         0% or 0 points

                          -50%         *-50% but reports as 0 points


* Since Lowest Possible Score is currently configured to be 0 points, score is reported as 0.

TURNING OFF THE AUTOMATIC CHECKBOX

If you turn off the Automatic checkbox, you are free to set the weight value for any of the possible answers.


For example you could configure Choice #1 to be worth 75% and Choice #2 to be worth 25% (both combined resulting in 100%).
