The list of response areas is maintained in the Teacher section here. In the Developer area (here), the behaviour of the response areas is documented.
If a user submits a response without inputing a value, the response areas convert the responses as follows before passing them to the evaluation functions:
| Input Value Type | Default Value | Comment |
|---|---|---|
| number | undefined | [Behaviour needs updating] |
| string | undefined | [Behaviour needs updating] |
| MATRIX | " " |
empty string in all cells |
| TABLE | " " |
empty string in all cells |
| MULTIPLE CHOICE | False |
all choices set to false |
