feedback by text
Introduction
While creating exercises an important issue is to give feedback to the user. You can do this by a text that's only shown when the answer is right. Following applet shows a easy example. The user has to drag a point to a given position. If the position is right, the text Correct! appears.
When clicking on the restart icon a new exercise is generated.
How do you do this?
- Point with random coordinates: Create:
a = RandomBetween(-4, 4) b = RandomBetween(-4, 4) P = (a, b) - Point to drag: Create a point A beyond the range of P
A = (-8, 1)Rightclick on the point, open the Properties of A ans select the tab Basic. Type P in the textfield Caption. - Exercise: Create a dynamic text showing the exercise. Select P in the tab Objects.
- Feedback:
- Create a text Correct!
- Open its Properties and select the tab Advanced.
- Type in the Condition to show the Object:
A = Pand Enter. - New exercise: - Online you can show the icon to restart the applet. a and b will be recalculated. - Offline you can insert a button to do this (see chapter 8).
