Moodle 3.2: Drag and Drop Markers Question Type
Applies to: Moodle 3.2.
Drag and Drop Markers is one of three new question types in Moodle 3.0. This question type allows students to drop markers with text onto an area on a background image. The question requires:
- The question text
- A background image
- Predetermined drop zones (circle, rectangle, or polygons)
- Markers - text answers
The instructor will upload a background image. Then using an overlaid grid pattern, determine the coordinate of the drop zone shapes. Each square of the overly grid equals 10 pixels; there are thicker lines at each 100 pixel mark. There are three basic shapes that can be used as drop zones:
- A circle requires a center point (x,y) and a radius. Example: 105, 105; 65.
- A rectangle requires the top, left corner, a width, and a height. Example: 0, 20; 170, 150.
- A polygon requires the coordinates (x,y) for each corner. Example (for a diamond): 15,90; 90,15; 165,90; 90,165.
A preview of your shape is visible after entering the coordinates, so adjustments can be made for the shapes. If a rectangles is not parallel to the top and sides of the background image, use the polygon formula for determining the drop zone.
Large background images will be reduced to a maximum 600 x 400 pixel size. When determining the coordinates for a shape, the upper left corner of the background image and overlaying grid is 0, 0 (x,y). Moving to the right increases the x value; moving down increases the y value. There are no negative values, only starting points and positive distances. It is best to make the drop zone too large than too small.
Creating the question
- From the course homepage:
- Go to the Administration block.
- Click Question Bank, then click Questions.
- On the Question Bank page:
- Select a Category to store the question.
- Click Create a new question and select Drag and Drop Markers from the list.
- Give the question a descriptive name.
- Enter the question into the text editor, using any formatting you wish.
- In the Preview section, click the background image button to upload an image.
- Larger images will be displayed at a maximum 600 x 400.
- Your image will then display under the file upload box.
- In the Markers section, add the words you want the students to drag onto the areas you select.
- Tick 'Shuffle' to randomize the display order of the choices.
- For the Number option, the common choice is "1". This allows an answer to be used only once.
- Manually to add the coordinates of the areas into which you want students to position the marker. (See available shapes listed above.)
- Once all co-ordinates have been manually entered, you can save the changes and preview the question.
