Thanks @e0d for your proposal!
I have a few remarks of proposal for discussion about your mapping proposal

I agree that it is not a result information. Have you checked that no extensions already exists for this ?

I did not see an extensions that seemed appropriate. I wonder if this data is just too unnatural to include in an xAPI statement.
@ormsbee do you have any specific recollection as to why this data was included in native Open edX events?

I don't have a recollection of it, but my guess would be because it matters for later analysis whether a student got the problem without hints, whether the hints helped them to get the correct answer, and which hint did so.

A best practice on xAPI is to use a parent in the contextActivities to describe from where the event was generated. Here this information is partially already contained in the parent. Some precision there is necessary. The use of extensions should be as minimal as possible

I suppose we must decide what is the appropriate parent for a specific question. Is it the course, sub-section, "assessment," something else?

@ormsbee I'd love your thoughts on this. I'd also like to consider how this might change as ALUs are developed.

I think it has to be the assessment/sequence/subsection the problem is contained in. Per the spec:
For example: a Statement about a quiz question would have the quiz as its parent Activity.
In a more ALU-centric world, I think this still works–problems will almost always be invoked as part of some larger thing.

Maybe could we use this existing extensions?

The attempt-id extension seems appropriate for identifying a specific attempt. This field in the tracking logs represents the count of attempts that a user has made.

Are you suggesting using school or school-center instead of org? The extensions seems a bit of a hodge-podge at times. I'm not sure who AcrossX are and am not sure if there's a special meaning in the navy for "school-center."
I agree that we should use existing extensions where possible.

@quitterie-lcs thoughts on whether http://adlnet.gov/expapi/activities/assessment or http://adlnet.gov/expapi/activities/cmi.interaction would be better here?
There was a problem hiding this comment.
I would say that CMI Interaction is more appropriate as it is a more general interaction concept that is, in this situation, applied to an assessment

If we're using a URL here, it might be useful to prefix /xblock/ to the path. That has the advantage of namespacing, as well as mapping to a real URL that renders the XBlock in question, e.g. https://demo.openedx.overhang.io/xblock/block-v1:edX+DemoX+Demo_Course+type@problem+block@303034da25524878a2e66fb57c91cf85
Opening this to facilitate a conversation about xAPI mapping of the problem_check event.
