   Assigning Weights

   Icon

   Weights affect the examinee’s score for an item. If weights are assigned to individual Answer Options, they affect the total score of an item depending on which (and how many) Answer Options are answered correctly or incorrectly. Assigning weights is optional and can be done via the Weight drop-down list.

   The default selection item is Default, which assigns a score of "1" to the item. The candidate scores "1" only when he/she selects all the correct Options and does not select any incorrect Options. Upon selecting even a single incorrect Option, he/she scores "0".

   

   If you choose to assign custom weight for the item, then you must select Item from the drop-down list. A text box appears next to the drop-down list, where you can enter the weight value for the item. The candidate scores the specified weight value only when he/she selects all the correct Options and does not select any incorrect Options. Upon selecting even a single incorrect Option, he/she scores "0".

    

   You can assign custom weights to individual Answer Options by selecting Option from the drop-down list. A Weight text box appears next to the Answer Options, where you can enter the weight value for the respective Answer Options. The weight value is a decimal number. Weights assigned to incorrect Answer Options are ignored.

   The candidate scores the specified weight value of the correctly answered Option(s), regardless whether he/she also incorrectly answers one or more Options. The maximum score of the item is equal to the sum of the weight values for the correctly answered Options.

   Item weight can be a positive decimal or integer value. It can range from ".001" to "9999".

   Option weight can be a positive or negative decimal or integer value. It can range from "-.99" to "9999".

Create a Point and Click Item

The item author specifies one or more area(s)/point(s) on the image to identify a correct response. ExamDeveloper provides an interface for users to create the questions. How they are presented to the candidate depends on the Assessment Driver used to deliver the exam. An Assessment Driver is software owned by a test delivery provider used to present items to candidates.

1. Enter the question candidates must answer in the Question Stem field. Enter the information or objective the candidate needs in order to respond appropriately.
2. Click the Select/Upload Image button above the Shape Editor to select an image for the item. The supported image types for Point and Click Questions are .JPG, .JPEG, .GIF, .PNG, .BMP, .DCM, . ODG, .TGA, .SVG, and .TIF.

3. Click the Retrieve Assets button. and then click the Attach Asset  icon for the desired asset.
   

   Icon

   For more details on attaching an image, refer to Upload an Asset.

   
   
   

4. Click OK when the image has been attached message appears and Close the Attach Asset pop-up window.
   The image is added to the Point and Click canvas editor.
   

5. Enter the Shape Labels you want to add to the image, one in each shape label field provided. Labels must contain text. You are prevented from submitting the item if any labels are empty.
   

   Icon

   The default setting is four Shape Labels, but the writer might choose to add or remove pairs. The minimum number of allowable labels is two. The writer can click the  Add Distractor icon after the stem to add a label and  Remove Distractor icon to remove the corresponding label, if the Allow Differing Option Count setting on the Questions tab of the project's Configuration page is selected.

    

    

6. Select the check boxes for the correct shape label field(s). Leave the check boxes for the incorrect shape labels as unselected.

   Icon

   In a Hot Spot item that is exported for the Athena test driver, the maximum number of clicks the candidate is able to select must be equal to the number of correct labels set on the item.

   
   
   

7. Select Hot Spot (default) or Hot Area radio button to determine how the candidate views the item in the Assessment Driver.
    
   • If Hot Spot is selected, the drop zones are not visible even when the mouse cursor is moved over them. When the candidate clicks on the asset in the Assessment Driver, a point is marked where they clicked. 
   • If Hot Area is selected, the drop zones are displayed as soon as the mouse cursor is moved over them. When the candidate clicks on any of the drop zones in the asset in the Assessment Driver, the entire drop zone is marked and becomes visible.
     
     
   In either of the above cases, candidates receive a passing score as long as they click within the drop zone.
   You are now ready to work with the inserted asset.
   
   

8. Using the editor functions described below, create the shaded areas that correspond to the correct response for each label. For every label, there must be a corresponding shape drawn on the image.

   Icon

   ExamDeveloper provides the tool to create these item types. It is important users realize while creating the item, that this is not necessarily what candidates will view. Rather, the candidate interface is dependent on the Assessment Driver that is used, and can vary between delivery vendors.

   For Point and Click Question Stems, the Asset Manager function is not available.

   The minimum number of shapes required is one.

   The shapes must be drawn within the boundaries of the image.

   
   
   

9. Specify the Blueprint, Reference, and Metadata for the item (as appropriate).
   

Editor Functions

   Swapped background image: shapes remain in the same location

   

   Note: Be aware that if shapes have been added to the image on the canvas editor, the shapes remain in place when you swap the background image. If the first image was large with shapes outside the standard viewing area of the canvas and you replace the image with a smaller image that fits within the standard canvas viewing area, the shapes remain in place. You must use the scroll bars to locate the shapes and move them within the image boundaries or delete and replace them prior to submitting the item.

   Icon

   If you zoom in or out on images that include shapes, the shapes retain their proportion to the image size.
