[Athen] Accessible Math formulas in Blackboard

[Russell Solowoniuk]

Hi all,

I'm working with one of our eLearning specialists. They are trying to make their STATS 151 Blackboard course more accessible. In the past they were pasting screenshots of the formulas into the course, which isn't at all accessible.

Now they are using the built-in Blackboard equations editor. The formula still goes in as a graphic, but the actual formula is placed into the alt text for that image. Below is an example, and I wonder if anyone familiar with Math can check this to see if it would be considered accessible? I read in a few places that this method is acceptable.

Descriptive Measures for Population and Sample

Population mean

[mu equals fraction numerator sum for blank of x subscript i over denominator N end fraction]

Population mean
[mu equals fraction numerator sum x subscript i over denominator N end fraction]

Population standard deviation
[sigma equals square root of fraction numerator sum for blank of left parenthesis x subscript i minus mu right parenthesis squared over denominator N end fraction end root]

=
[square root of fraction numerator sum for blank of x subscript i squared over denominator N end fraction minus mu squared end root]

[x with bar on top equals fraction numerator sum for blank of x subscript i over denominator n end fraction]

There's more to this formula, but just want to see what you all think. In the Blackboard course, I am able to read the alt text tags as if it were just text, but I noticed in the images I pasted above, I am not able to do this.

Thanks,

Russell
