[BlindMath] Accessibility for Stats courses

Wed Sep 13 14:48:25 UTC 2017

Tex4HT is great, but it cannot solve the problem of missing or incorrect information - which is what I have found to be the only significant problem in transforming LaTeX to MathML. 

* Biggest problem: When the author has used macros but you do not have the macro definitions, there's not much any application can do. The only solution I know is to enlist an expert to help. An expert in the field who also understands Latex may be able to recognize what the author's intent was and then create a macro definition package for you. 
* Smaller Problem: It is easy to use symbols in Latex that look right but are not. One that I remember is the use of wrong bars around determinants. MathML is a bit particular about such symbols, and I have seen some strange equations resulting from the use of wrong bars.  Fortunately once one understands the problem it is easy to do a search-and-replace on the Latex to put in the right symbol.
* Smallest problem: There are some Latex symbols that do not have unicode equivalents. I do not remember any examples but I know there are some. This is unusual but it can happen. Solution is to replace it with  a different symbol that has a unicode equivalent.

Good luck.

John

Yes, it does support MathML. I have not tried it, however, so the best I can do is to refer you to the documentation for the details.

As an aside, does tex4ht support Math ML? Would be useful for some documents I’m working on.

This was helped along by the use of both pdf and HTML formats during the authoring process. I used this strategy a lot over the years because the HTML is easy for me to digest.

All single and double quotes were coming out in very peculiar ways and my attempt to alter the character encoding to fix that yielded an article with no line breaks. I would happily read that version if it were a matter of personal consumption, but I'm trying to fix it for putting on the web like the first one above. TO do so means losing many of the journal's style features that have little value to a blind reader. I've needed to suppress those for the conversion to HTML.

> This is the paper that was inspired by the experiences of people on this list (and others) as well as a summary of many tools suggested by people on this list. It is filtered to the problems and solutions found in statistics courses specifically because that relates to the authors’ expertise, and it was published in the Journal of Statistics Education with the intention that the instructors of statistics courses are our primary audience. This paper has been used by blind students as a tool for making their pathway through a statistics course all that much easier and more successful. I’ve had positive feedback from students, parents, and most often, from instructors about the paper. In the end, I feel that we achieved more than just an academic research output. As academics, Theodor and I put our colleagues on notice that they can and should be prepared to assist a blind student coming into their classroom. We acknowledged this list as a primary tool for communication of ideas and solutions and I believe what we did was entirely in keeping with the general culture of this community. We did it our way; others will use a different tool to help us all get more blind students succeeding in STEM disciplines.

There are numerous individuals that have made contributions on this list that I have valued. I consider myself fortunate to have met quite a few of them at the NFB Convention in July.

> I’ve never said succeeding in STEM is easy. It isn’t for sighted people either, but they do find it easier than we do as blind people. I do think the difference in success in STEM versus other disciplines is reducing though, in part because so many other disciplines are incorporating things that were previously in the domain of the STEM geeks. The question for me, which remains unanswered, is whether that difference is widening for blind people. I think it has over the last twenty years or so, but I do believe the tide is turning.
