Moodle 3.0, 3.2: Drag and Drop Markers Question Type
Applies to: Moodle 3.0, 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.
