Graphic Gap Interaction

The Graphic Gap Interaction gives Test-Takers the opportunity to demonstrate their knowledge about geographical regions, identify facts about portions of images (people in a group photo, etc.), or show other similar capabilities in picture matching.

This interaction is one of a series of Graphic interactions (the others are covered in their own sections). All graphic interactions can be found in the Graphic Interactions menu in the Library.

Once you have generated a new Item, and clicked on Authoring in the Action Bar, follow the steps below to create a new Graphic Gap Interaction:

1. From the Graphic Interactions library near the bottom of the Interactions library on the left, drag the Gap Match icon onto the blank Item and drop it onto the canvas.

2. Choose the desired background graphic.

A Resource Manager window will appear with which you can select a background graphic. You can re-use a background already in the resource manager, or you can upload a new one. To select one from the list of previously uploaded graphics, highlight the appropriate background graphic in the resource manager list and click the green Select button. To upload a new one, click on the blue Add file(s) button to browse the files on your computer, and then upload one to the resource manager by clicking the green Upload button.

Highlight the file you have chosen as your background by clicking on it, and it will appear on the right in the preview panel. Click Select in the bottom right of the window to continue.

A new authoring window will appear with the background graphic in the center of the canvas. Above the graphic there is a question field. On the left there is an Associable Hotspot Panel for inserting selected shapes that will represent Associable Hotspots into the background graphic (these include four different shapes: rectangle, circle, ellipse, and polygon). Below the Hotspot Panel there is a trash can icon, which allows you to delete a poorly-placed or misshapen Hotspot. Below the graphic is a gap match field where the answers should be entered (in the form of graphic elements).

3. Fill in the question field, where it says 'define prompt'.

This should cover such important information as what the graphic represents, and what the test-taker is supposed to do in this interaction.

Note: The A icon on the right allows you to bold or italize text, and to insert a picture, shared stimulus, math expression or link into your question.

4. Insert the Associable Hotspots onto the graphic.

To insert a rectangle, click on one corner and drag it across the intended area the Hotspot is supposed to cover. To insert a circle or ellipse, select its center and drag outward or inward until the Hotspot is the right size. To insert a polygon, begin at one corner, then click on each corner in succession until the Hotspot is complete. You can make all the shapes bigger or smaller (or in the case of polygons change the shape), but if necessary, click on the problem Hotspot, then click the trash can to delete it, and then try again.

After inserting the Hotspots, enter the answer graphics will in the gap match field below the background graphic.

5. Click the plus sign (+) within the gap match field as many times as is needed to create the correct number of gap match slots.

Clicking the plus sign will bring up the resource manager window. As during placement of the background graphic, the immediate choices will include all recently uploaded images. Simply select one graphic for each slot, or upload the necessary graphics.

Before uploading, resize the graphics: all graphics should be roughly the same size - ideally, a width that is one-sixth the width of the background graphic. If the selected graphics are not this size, they should be resized before uploading.

Once all the images are the correct size, click on the blue Add file(s) button at the top of the list of available graphics to locate and upload all the desired image files by clicking the green Upload button below the list.

After uploading the images, select the first answer graphic for the first slot, and repeat for all subsequent slots.

6. Click Response on the right of blue interaction header to define the correct answer(s).

You can now select the correct associations between the answer graphics and the Hotspots on the graphic. To do this, drag and drop each answer graphic onto its corresponding Hotspot.

6. Click the blue Done button. Your Graphic Gap Interaction is now complete.

You can now preview your Interaction using the steps given in the Preview instructions.
