Iknow that simple choice is "QUESTION_TYPE_CHOICE", and TF for true-false, can you tell me what's the key for multiple? Thanks Hi,
great article, i’ve one question: how can I implement multiple choice? Iknow that simple choice is “QUESTION_TYPE_CHOICE”, and TF for true-false, can you tell me what’s the key for multiple?

Thanks

For question types such as multiple choice, the specification requires that the response be formatted as a single alphanumeric character. That gives the content author limited options. The content can report that the user gave the answer "c" and the correct answer is "a"...but what should happen if the order of the presented questions is randomized for each user. Some content will report the first letter of the text of the answer, but that has obvious drawbacks when different responses start with the same letter. Other content simply ignores the single character requirement and reports a more descriptive value. SCORM 1.2 is a bit lax in its enforcement of these restrictions and many LMS's will accept multiple character identifiers in order to provide good reporting.<br/><br/>We recognize that this is a problem both on the content and LMS side. In the SCORM Driver, when content reports an interaction result, we ask for both a short and a long identifier. The Driver can then be configured to attempt to persist the long identifier if the LMS will allow it, but if not, it will fall back to persisting just the short identifier. This lets the content be both strictly conformant yet also provide useful information. Similarly on the LMS side, in the SCORM Engine there is a package property that controls whether or not the LMS will require strictly conformant SCORM 1.2 interaction results or if it will relax the validation and allow more descriptive values to be recorded.
