Context

+

Maths, Stats and Physics has around 900 undergraduate students and around 100 taught modules.

+

In MSP, over 13% of students have an SSP, compared to 6% in Engineering and 7% in Computing. Many students without SSPs would benefit from accessibility improvements.

+

Maths is different: typesetting mathematical notation is hard, and typesetting maths in accessible formats is even harder.

+

Lecturers typically prepare material in LaTeX or write by hand in lectures.

+
+ +
+

Chirun

+

Chirun is a tool to produce accessible course material from LaTeX or Markdown source, developed here.

+
+ Chirun +

+
+
+ +
+

The beginning

+ +

We introduced Chirun in 2017 to support an incoming student with long list of accessibility requirements.

+

To speed things up, we paid students to type up existing handwritten notes in LaTeX.

+

Aim: improve accessibility for all teaching, not just this student. Provide a consistent level of accessibility that enables almost all students to access their material without adjustments.

+
+
+

๐Ÿฅ• The carrot

+ +

I talked at the school's all-staff meetings about how students struggle with existing material and how to use our tools to produce accessible content.

+

We offered support to anyone who wanted it: we'd take their material and make it accessible.

+
+ +
+ + + +
+ +
+

๐Ÿ˜‡ (some) Lecturers take accessibility very seriously

+ +

Many lecturers responded positively and gave us material to run through Chirun.

+

A handful of lecturers understood the brief and produced accessible material on their own. Thanks!

+

Some used their own tools, such as Bookdown.

+

After a year, some modules had all material available in accessible formats.

+
+ +
+

๐Ÿ˜  (some) Lecturers don't take accessibility seriously

+

After two years, take-up was very low: less than 25% of modules were acceptable.

+

Common complaints:

+
+ +
Why should I do all that for one student?
+
Every student deserves to learn!
+ +
Is this student even any good?
+
Doesn't matter!
+ +
I'm overworked and don't have time to do this.
+
So let us help!
+ +
I don't know what to do.
+
Let us show you!
+
+
+ +
+ + + +
+ +
+

๐Ÿงน The stick

+

Using my Canvas admin role, I audited every module twice a semester.

+

I passed findings on to the director of education and directors of discipline, who talked directly to lecturers.

+

I emailed individual lecturers offering to take the job off their hands if they'd send me their material.

+
+ +
+

โœ”๏ธ This mainly worked!

+

Now, more than two thirds of modules have all material available in accessible formats.

+

Many physicists use PowerPoint and I can only offer them advice. ๐Ÿคท๐Ÿป

+

We've moved on to looking at other aspects of accessibility: in-person delivery, communication, lecture recordings, โ€ฆ
