<h1>Context</h1>
|
||||
<p>Maths, Stats and Physics has around 900 undergraduate students and around 100 taught modules.</p>
|
||||
<p>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.</p>
|
||||
<p><strong>Maths is different:</strong> typesetting mathematical notation is hard, and typesetting maths in accessible formats is even harder.</p>
|
||||
<p>Lecturers typically prepare material in LaTeX or write by hand in lectures.</p>

|

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

<h1>The beginning</h1>
|
||||
|
||||
<p>We introduced Chirun in 2017 to support an incoming student with long list of accessibility requirements.</p>
|
||||
<p>To speed things up, we paid students to type up existing handwritten notes in LaTeX.</p>
|
||||
<p><strong>Aim:</strong> 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.</p>

<h1>🥕 The carrot</h1>
|
||||
|
||||
<p>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.</p>
|
||||
<p>We offered support to anyone who wanted it: we'd take their material and make it accessible.</p>

<h1>😇 <small>(some)</small> Lecturers take accessibility very seriously</h1>
|
||||
|
||||
<p>Many lecturers responded positively and gave us material to run through Chirun.</p>
|
||||
<p>A handful of lecturers understood the brief and produced accessible material on their own. Thanks!</p>
|
||||
<p>Some used their own tools, such as Bookdown.</p>
|
||||
<p>After a year, some modules had <strong>all</strong> material available in accessible formats.</p>

<h1>🧹 The stick</h1>
|
||||
<p>Using my Canvas admin role, I audited every module twice a semester.</p>
|
||||
<p>I passed findings on to the director of education and directors of discipline, who talked directly to lecturers.</p>
|
||||
<p>I emailed individual lecturers offering to take the job off their hands if they'd send me their material.</p>

<h1>✔️ This mainly worked!</h1>
|
||||
<p>Now, <strong>more than two thirds</strong> of modules have all material available in accessible formats.</p>
|
||||
<p>Many physicists use PowerPoint and I can only offer them advice. 🤷🏻</p>
|
||||
<p>We've moved on to looking at other aspects of accessibility: in-person delivery, communication, lecture recordings, …</p>
