Verification
Verification quizzes are useful for making the learner think about the question as there is no easy way to reach the answer and it has to be correct.
For example the learner can be asked to complete a calculation and submit the result into a text box, the result is verified against a known answer(s) and they receive feedback. In the event of an incorrect answer feedback can be given in the form of a hint with a correct answer being required to be successful.
As this question type requires no coding to develop in the VLE, staff must consider whether this type of quiz should be used in the HTML5 learning object or in the VLE.
Example 1
Given the following information, calculate the volume of a cylinder that is 10cm high and has a diameter of 5cm. Round your answer to 2 decimal places and type it into the box provided.
Formula: V= πr2h
The volume of the cylinder is: cm3
Example 2
In this enhanced version of example 1, the learner fills in the blank boxes then clicks on the ‘check answers’ button.
The answers are verified against a list of correct answers. Those answered turn green and incorrect answers turn red. An incorrect answer hint is also given to prompt the learner to check.
| Diameter(d) D | Height(h) H | πr2 | Units | Volume | Units |
|---|---|---|---|---|---|
| 10cm | 0.5m | cm3 | cm3 | ||
| 0.7m | 2m | cm3 | m3 | ||
| 1.5m | 10m | cm3 | m3 | ||
| 3cm | 2.5m | cm3 | cm3 | ||
| 0.75m | 10cm | cm3 | cm3 |
Formula: V= πr2h
The answer we would be looking for in this example activity is 196.35 cm3.
We could also provide a hint for an incorrect answer, for example:
Hint
Have you remembered to halve the diameter to find the radius? Have you remembered to square the radius?
Enhanced version of example 1
When the learner fills in the blank boxes and clicks on the ‘check answers’ button, their answers are verified against a list of correct answers. Those answered correctly will turn green as shown below.
| Diameter(d) D | Height(h) H | πr2 | Units | Volume | Units |
|---|---|---|---|---|---|
| 10cm | 0.5m | 78.54 | cm3 | 3926.99 | cm3 |
| 0.7m | 2m | 3848.45 | cm3 | 00.77 | m3 |
| 1.5m | 10m | 17671.46 | cm3 | 17.67 | m3 |
| 3cm | 2.5m | 7.07 | cm3 | 1767.15 | cm3 |
| 0.75m | 10cm | 4417.86 | cm3 | 44178.65 | cm3 |
Incorrect answers will turn red and a hint will be provided to the learner, for example:
Hint
Have you remembered to halve the diameter to find the radius? Have you remembered to square the radius? Have you converted all your sizes to the same units? Did you convert the volume units from cm3 to m3 where required?
