[Athen] QTI 2.2 specification, MathML, and drop down interactions

[steve.noble at louisville.edu]

Hey Sean,



We (the APIP accessibility task force) are actually working on a best practice document for associate interaction and match interaction in the short term, and in the longer term coordinating with the AQTI architecture activities regarding prototype implementations and which aspects of user interface accessibility to incorporate in updates to the QTI specification. None of this is near completion, but I can try to touch base with those taking the lead on this work and pull you into that discussion offline, it that would help.

Thanks for the contact, Steve.

In part, I am trying to understand if it is I who is misreading the spec or if the developers are trying something that is technically conforming but functionally not usable. We are also using MathJax, although it is being used in its default implementation. We did try a number of alternative solutions (aria labels, off-screen text, etc.) as well as modifying the Angular-Bootstrap component, but nothing seemed to work.

I do need to have an immediate solution, but I would like to address the root issue. The developers keep insisting they are following the specification and because this is considered valid, the issue is believed to be with the assistive technology, not with the implementation. Unfortunately, there is little guidance as to how one should implement this specific interaction type so that it also supports accessibility.

Is there going to be an update to the APIP documentation or is it considered current for the QTI 2.2 specification?

Thanks again,
Sean

Actually, this issue has surfaced in some of our APIP accessibility task force meetings. You may want to reach out to Paul Grudnitski from Pearson ‎[paul.grudnitski at gmail.com<mailto:paul.grudnitski at gmail.com>], as he has developed some sample content where he used MathJax in a special configuration to get past this issue. This assumes that your interest is in getting something that works now in your specific implementation, as opposed to fixing the root problem for all mankind.

Sean,

It sounds like you found an interesting bug — maybe in QTI or maybe in the component coding or the browser you are using. You may find people who can help answer your question in the IMS forum for QTI:

Subject: [Athen] QTI 2.2 specification, MathML, and drop down interactions

Hello,

I have an assessment application that developers are building according to the QTI 2.2 specification. One of the interaction types is that of a dropdown choice (like a <select> menu) but implemented using Angular-Bootstrap. It is based off the following:
https://angular-ui.github.io/bootstrap/#/dropdown<https://urldefense.proofpoint.com/v2/url?u=https-3A__angular-2Dui.github.io_bootstrap_-23_dropdown&d=AwMFAw&c=SgMrq23dbjbGX6e0ZsSHgEZX6A4IAf1SO3AJ2bNrHlk&r=4WMck1ZVLo4tV0IVllcBNKXCSGU6lUERtx_4HD4DqmE&m=lZpgVCI4j4dV7RAbyJgsPr6gvi2ev39UulE4tTAhJ2g&s=VHmk1_qhD-6DkFzTrCamkasNg6U7ZqLemEE9i9z0rD0&e=>

As an example - there could be a sentence with a word missing and the dropdown menu would offer several choices so as to complete the sentence.

While this interaction type can be made accessible and works fine for text content, it fails when MathML is used to present any math content. Visually the math is presented, but the MathML content cannot be read by any assistive technologies. In fact, interacting with this component from the keyboard becomes problematic if any AT is running at the time.

As part of the IMS QTI 2.2 specification, MathML is "approved" for use in certain interaction types, one being InlineChoiceGroup in which the dropdown interaction is used. We have AT that supports MathML and yet by following the IMS QTI 2.2 specification, that content is no longer communicated to the user.

I have been reviewing the Accessible Portable Item Protocol and best practices, but this points to the QTI 2.1 specification and does not appear to provide any direction as to how to resolve such an issue.

Looking for suggestions from anyone who has any experience with these specifications.

Take care,
Sean
