I have now started studying for IAAP exam Certified Professional in Accessibility Core Competencies (CPACC). While I thought I was working towards the qualification for a while now, in April I realised there has been a syllabus change in 2023. This is the latest body of knowledge available on IAAP website IAAP CPACC Body of Knowledge October 2023

Accessible Social Media: Tweets
In this blog, I am going to discuss how to make your Tweets accessible. I have created accessible and inaccessible Tweets using my account to show as examples and used Windows Narrator to record the audio of the screen reader experience.
Inaccessible Tweet

| Inaccessible Tweet with many accessibility issues |
Transcript: Inaccessible Tweet
I hope you agree with me that was not a great experience. Now, let’s try to make this tweet more accessible by adding alternative text for images, using Camel case for hash tags, adding only necessary emojis and including hash tags and Twitter handles at the end of the message.

| Accessible Tweet showing good practice |
Listen to the more accessible Tweet on the screen reader
Transcript: Accessible Tweet
Posting this tweet to demonstrate the importance of accessibility. This is more accessible. Use emojis only when necessary. Add alternative text for images hashtags in camel case at the end. Link hash no access. Link Hash poor accessibility. Thumbs up sign image. Link image demonstrating bad practice of green and red use to differentiate answers. Link image answers differentiated by red and green cannot be distinguished by a person with monochromacy achromatopsia.
The second version of the tweet is more accessible because:
- it makes it easier for the user to follow the content as there are no hashtags (or Twitter handles) in the middle of the tweet
- Camel case is used for hashtags making them read correctly
- Emojis are used sparsely making it easier for the user to understand the Tweet
- Images are described.
- Use hashtags and handles at the end of the post
- Use Camel case for hashtags
- Use emojis sparsely and only when necessary
- If you are using images, describe them by including an alternative text description
There is good
practice around the use of colour and more information on creating accessible content on the Digital Accessibility
at the University of Reading web space. View Resources about making content more accessible.

Making equations accessible
Today I watched the JISC Accessibility Clinic recording A collaborative approach to maths accessibility learning a lot about the challenges in making math or STEM content accessible.
I have used MathJax and MathML with Moodle and have blogged about it earlier in my work at UCEM.
- Using MathML with Moodle
- Mathematical Equations in Moodle
- Accessibility of Mathematical Equations with Screenreader
- Generating MathML Code for Equations with MathType
hypotenuse = (a^2+b^2)^0.5 because I am not familiar with MathML to make it work.
Then write your code
<p> \ [hypotenues = \ sqrt{a^2+b^2}\]</p>
There are no spaces between backslash and the character next to it but to show how to write the equation I am adding spaces
Then the MathJax will make it look like
\[hypotenues = \sqrt{a^2+b^2}\]
There are obviously some notations to learn.

\[...\] for displayed mathematics
\(...\) for in-line mathematics and lots more for various operations.

Find Colour Contrast
Sufficient colour contrast is important to make it easier for people to recognise foreground from background. There are three WCAG 2.1 guidelines on accessible colour contrast and they are:
1.4.3: Contrast (Minimum) AA
- Text contrast ratio of at least 4.5:1
- Large text 3:1
- 18 point text or 14 point bold text is judged to be large enough
1.4.6: Contrast (Enhanced) AAA
- Contrast ratio of at least 7:1
- Large text 4.5:1
1.4.11: Non-text Contrast AA
- UI component and graphical objects to have 3:1 contrast against adjacent colours
- Hexadecimal value
- RGB value
- Using colour picker

UCEM Accessibility Awareness Course
I really wanted to create an accessibility awareness course that is open to anyone. I learned a lot about accessibility from MOOCs such as "Access MOOC" and "Professional Web Accessibility Auditing Made Easy" by Ryerson University when these were available free for everyone. However, a lot has changed since 2016 and now most of the courses are paid for even on MOOC platforms.
My application to a funding body to create an open course was not successful. Since then I have taken the time to create this course for UCEM and I hope I would get the chance to publicly make it available with CC license.
The course consists of sections that offer seven milestone badges leading to a final Accessibility Awareness Badge.

These beautiful badge images were created by my colleague Asma Hussain

Zoom webinar transcripts and accessibility: What our students think
97.8% of the students have watched at least one recorded
webinar session, demonstrating the importance of recorded webinars for our students.
Only 144 students (52.7%), however, had used the audio transcript, 14 students
(5.1%) were unaware of the availability of the transcript facility and 115
students (42.1%) indicated that they had not used the audio transcript
facility.
A follow-up question, ‘Did you find the transcript useful?
Why?’, was asked of the students who indicated that they had used transcripts.
Out of the 130 students who answered this free text question, 104 students (80%
of those who responded to this question) agreed that the transcripts were
useful while 14% indicated that the transcripts were not useful. Out of the 92
respondents from non-English speaking countries (excluding respondents from
majority English speaking countries), 40 responded to the free text question, ‘Did
you find the transcript useful? Why?’. Only two respondents said that the
transcripts were not useful. The large majority, 95% of students who have
English as a foreign language and responded to the question, found transcripts
a useful addition to understand what is being said in the webinars.
Many students who have used the automatic transcripts found
them to be useful.
One response stood out for me:
So useful! Amazing. The search functionality is revolutionary. If I vaguely remember something being said in the webinar but can't quite remember where or when I used to have to watch almost the entire webinar again - and it took so long to load. Now, I just type a word and everything comes up. It's amazing. Ok, the audio transcript is not always spot on, but frankly it's amazing how much it does pick up especially with different accents and pronunciation of words and acronyms. Really love it.
The study found that many students appreciated the availability of automatic transcripts despite their less-than-perfect accuracy level. Students used transcripts mainly as a tool for searching within a video. This small study shows that students used transcripts in multiple ways:
- skipping to a specific location in the video
- as notes
- as an accessibility aid
- to overcome unfamiliar accents and words such as technical terms
- to follow the pace of a fast speaker
- to study ‘on the go’ – in quiet places, for example
- to catch up if distracted
- compensating for poor audio and/or connectivity
- as an alternative format for video
- as an aid for non-native English speakers.
·
despite 31.1% of students not using any Zoom
guidance provided by UCEM, 89.3% agreed with the statement: ‘I was able to join
the Zoom session with ease’
·
97.8% of the students have watched at least one
recorded webinar session. 89.4% students agreed with the statement: ‘Do you
agree that Zoom provides good quality audio and video?’
·
of the students who have previously used
Blackboard Collaborate, 72.9% preferred Zoom
·
81.5% of students prefer facilitated webinars.
Students identified three main functions performed by facilitators in webinars:
monitoring chat and supporting the smooth run of Q&A during a webinar;
helping with technology; and helping with non-subject specific information
·
many students watch recorded webinars and want
them to be available soon after a webinar
·
there were some instances where students in
certain localities (especially parts of the Middle East) could not access the
software due to local restrictions. For these students, the recorded webinars
were made available on a video-sharing platform.
To find out more about the study, take a look at the full
research paper.

eLearning in Challenging Times: Homeschooling UK
Homeschooled your children during the COVID-19 lockdown? We would love to hear from you.
Homeschooling UK Survey is now open (anonymous 10-15mins)
In March when the UK government closed schools and imposed lockdown restrictions, to stem the spread of COVID-19, we all were hurled into a situation that we have never been in before. While adjusting to the life with new measures like social distancing; no pasta, rice, flour or toilet rolls on supermarket shelves; and setting up our “home offices” (wherever there was a space on a table top) – some of us who have young families, had to learn to “homeschool” our children while also doing our fulltime jobs.

As a mother to primary school twins, I can tell you how amazing, frustrating, infuriating and many other adjectives can be added to describe this experience. We started taking in a day at a time first. But soon we reduce that to an hour at a time as we realised even a day is too long time when doing juggling homeschooling with a full-time job.
In April when I was put on furlough I was worried how I would fill my days. But later when I started getting into proper homeschooling, I realised even the furlough time was not enough! My furlough time came at a crucial time as the twins were getting ready for their eleven plus (secondary school entrance tests).
One of the best things we did before the lockdown was collecting a box of hand-me-down books from a friend's place. These books were used workbooks. But I could copy questions (either by hand - yes, I copied them in my new found 'free' time - or using the until then under used home printer). These workbooks together with BBC Bitesize, IXL subscription and the work sent home by school kept us going until the summer school break.
The researcher inside me wanted to gather the experience of eLearning in challenging times and I was not alone there. I soon found collaborators in Japan, New Zealand, Egypt and Sri Lanka who wanted to do similar work and possibly draw comparisons. We wanted to do both homeschooing experience as well as the experience of higher education students – however, with the pressing needs of "Transform" project at work (where we transformed all our Autumn 2020 offering) I was only able to progress on the homeschooling study.
So far, we have launched two surveys:
The survey is designed as an anonymous survey and to take no more than 10-15 mins of time. We hope to gather homeschooling experiences from parents and caregivers of young people.
If you have homeschooled a young person during the school closure period due to COVID-19 pandemic and you are a resident of UK (or Sri Lanka) please can you participate in our survey please?

Research in Distance Education (and eLearning) Conference RIDE2020
This year RIDE2020 was on 13th March and at a time when everyone is starting to worry about the spread of Corona virus. When I left Reading I knew there will be few people because on the train to London I got a seat! Circle line from Paddington too was very quiet. On the train I was thinking how to greet people now that most people are not comfortable with shaking hands.

| Tweet from Friday 13 March 2020 |
It was lovely to meet so many known faces and also to grow my network by getting to know like minded others. It was great to listen to Prof. Allison Littlejohn and getting to know some interesting and highly relevant work conducted by the London Knowledge Lab (such as iRead and Connecting Displaced People). Afternoon keynote was by Prof. Martin Weller, which was presented remotely. He talked about Open ed as the anti-disruption.
My presentation about how transcripts were used by students at UCEM was the last presentation on the day in one of the parallel sessions. My slides Automatic Transcripts: Student and Tutor views from Built Environment Education are shared in SlideShare. Despite my session being the last, there was good engagement and questions from the audience, I think especially because accessibility is an area that is very relevant in the UK with the new accessibility regulations - The Public Sector Bodies (Websites and Mobile Applications) Accessibility Regulations 2018.
This conference amidst the Covid-19 spread showed that perhaps we need to re-think about attending conferences in person when there is long distance travel involved - especially air travel. Perhaps, we can reduce air travel and be more green and sustainable by presenting our work online. Martin presented his keynote remotely and it was done skillfully. The keynote was engaging and it showed even the keynotes at conferences can adapt to Covid-19 and can also adapt to fight against climate change. Two other sessions I attended too was presented via Zoom and they worked almost perfectly. Once in a while there was few words that we missed due to poor connectivity but it didn't harm the experience.
My next conference is OER20 which is also going to be held online due to Covid-19. So this year many conferences will be run more environment friendly way. Perhaps this crisis is a wake-up call for us to think about being more sustainable and green in attending conferences?

Understanding Accessibility of PDFs
So I spent some time studying the WebAIM PDF Accessibility and PDF - the Print Devil's Format? and trying to create an accessible PDF from a document that wasn't read properly by the screen reader. Here I am sharing what I learned hoping it will help someone else too.
Best Thing to do ..
- headings
- alternative text for images
- table structures (make sure table header row etc is indicated)
- descriptive links
- lists
- columns
- text size, font (San Serif fonts are easier to read), spacing and justification (left justified letters are easier to read)
- colour contrast
- not using colour to differentiate meaning
- document title
- document language

Content vs Tag Order
According to WebAIM tutorial's Repair the Content and Tag Order section, the changes made in the Order pane is reflected in both Order pane and Tags pane but they say it can be unpredictable and it is best to complete Order pane first and then verified in the Tags pane.
Table Editor
With Reading Order dialog open you can either select the table and right click to elect the Table Editor or Select the Table Editor from the Reading Order dialog itself. You can also select Edit Table Summary from right click menu to add a summary to the table.In the Table Editor, borders of the table will be highlighted. In the Table Editor mode you can right click to show Table Cell Properties. Now you can specify whether the cell is a Header Cell or a Data Cell. If the Cell is a Header Cell, then assign the scope as appropriate.
After making the changes, verify table structure with the Tags Panel. Tables with multi-level row or column headers or cells spanning multiple columns or rows may need careful work to ensure they will be presented correctly by screen readers.
I have only given a quick introduction to using the Table Editor. In Adobe Help site PDF Accessibility Repair: Examine and Repair Tables is a good tutorial to follow.
Set Alternate Text
To show the Accessibility Tools panel for the first time go to Tools Tab > Accessibility and Add the accessibility tool. From the Accessibility pane select Set Alternate Text Tool. It will identify all images and allows you to add alternate text for these.Accessibility Checker
I am not still sure I am fully confident on making a PDF file accessible. At least I know what and where to look for if something isn't working right :)

Good practice for accessibility
I came across Lee Fallin and Sue Watling 's Designing for diverse learners poster where they have adapted work from Accessibility Poster Series from the Home Office Digital. I am promoting accessible materials at UCEM and was looking to put up some posters in the Hub area (communal space) to remind my colleagues of accessibility good practice when I found Lee and Sue's poster shared with CC license.
Though I have published some of my work with CC license in open access journals, this is my first re-mix of CC licensed work . I wasn't sure how much of a change was considered a re-mix. So after talking to Lucy, Information Governance Manager at UCEM I am confident in publishing it with share-alike license similar to the work I adapted. Asma, our Graphic Designer at UCEM, helped me by designing it with her graphic design software and saving it as a PDF.

In this version of work, we wanted to say why we needed to do each of these suggested accessibility enhancing steps. For example, we should not use colour as the only means to convey meaning (e.g. red letters for wrong answers and green letters for correct answers) because colour-blind learners may not be able to access the content as they may not be able to distinguish the different colours. I think giving reasons why something needs to be done in a certain way makes it more real as people can make connections.
This poster was designed to be visual as we are hoping to print it and display it at UCEM. I also created an accessible version of this poster in a text only version which can also be downloaded.
Again I want to thank Lee and Sue for their amazing work. Had they not shared this with CC license we would not have been able to adapt it.

Visiting Sri Lanka with Gluten Intolerance
![]() |
| Elephants (@pen_ash from Pixabay) |
In Sri Lanka, I have not seen shops actively catering to various food intolerance - may be due to the low demand?
My colleague is back safe and sound and have not have had any problems with food and she thanked me for the translations. So they have been proven ;)
The statements my colleague wanted me to translate are here:
- I would like plain boiled rice please. Talking with her what she actually wanted to say was "Give me plain rice portion. Not fried rice" so I translated that to Sinhala
මට à¶±ිà¶šං à¶¶à¶් (à¶´්à¶½ේà¶±් රයිà·ƒ්) à¶‘à¶šà¶š් දෙà¶±්à¶±. à·†්රයිà¶©් රයිà·ƒ් à¶‘à¶´ා. - I cannot eat any wheat flour or I will get sick. In Sri Lanka, people generally call wheat flour as bread flour and some people may not even recognise what wheat flour is. So this was my translation for her.
මටà¶ිà¶»ිà¶Ÿු à¶´ිà¶§ි (à¶´ාà¶±් à¶´ිà¶§ි) වලිà¶±් හදපු à¶šෑම à¶šà¶±්à¶± à¶¶ැà·„ැ, à¶šෑà·€ොà¶් මම à¶½ෙà¶© à·€ෙනවා. - I cannot eat any bread or I will get sick. Here I added flat bread, which is popular in Sri lanka as these are also made of wheat flour.
මට à¶´ාà¶±්, à¶»ොà¶§ි à¶šà¶±්à¶± à¶¶ැà·„ැ, à¶šෑà·€ොà¶් මම à¶½ෙà¶© à·€ෙනවා - I cannot eat any soy sauce, barley or vinegar either.මට à·ƒෝයා à·ƒෝà·ƒ්, à¶¶ාà¶»්à¶½ි à·„ෝ à·€ිà¶±ාà¶šිà¶»ි à¶šà¶±්à¶± à¶¶ැà·„ැ.
- Does this food have any wheat flour in it?
මේ à¶šෑමෙ à¶ිà¶»ිà¶Ÿු à¶´ිà¶§ි (à¶´ාà¶±් à¶´ිà¶§ි) à¶ිà¶¶ේද?

Research and Innovation in Distance Education, and eLearning (RIDE) 2019
The opening keynote was presented by Maren Deepwell, Chief Executive of the Association for Learning Technology She revealed some of the results from ALT survey and trends identified 2014-2018. Highlights were that lecture capture was up 20% and assistive technologies up by 7%. She also talked about the gender bias and suggested the reading Invisible Women: Data bias in a world designed for men by Caroline Criado Perez.
Then when it came to the parallel sessions we decided to go to the three different tracks so that we would be able to cover the whole conference between the three of us - however, in hindsight this was not a great approach as some presentations were not very engaging at all.
David Baume's session What information capabilities do your graduates need and what practices and policies will help them to achieve these? was an interactive session which discussed the importance of guiding students to build information literacy skills. We are trying to be helpful by providing our students with the most relevant articles - especially as distance educators we want our students, often time poor learners who are at higher risk of drop-out (than mainstream university students), to succeed. You provide all materials and students do not have to search for reverent material. So by being more helpful are we hindering them and their skills development in information literacy? David used the analogy of teaching his granddaughter crossing the road. How he helped her realise what were the dangers to look out for. Yes a car is a danger but only if it is moving towards you not away from you. The narrowing down process is where you can help your learner develop their own judgement. So in the first year we can provide most of the materials required but as they move on to second and third year give them more chance of putting their Information Literacy skills to work. It really made me think of our practice at UCEM. With our No Student Left Behind initiative, we have tried hard to provide as much support to students as possible, but are we inadvertently hindering them? Information Literacy skills are not just for the induction week/module - we need to support our students to build their skills over the course of their studies with us.
By the way, now I am using David's method of narrowing down process with my twins teaching them how to cross the road so it was a very worthwhile session :)
Then I attended Sarah Sherman's On your marks, get, set, study! Preparing students to be digitally ready for learning where she presented a course with 4 units they have put together for the UoL institutions.
- Unit 1: General Technology
- Unit 2: Learning Technologies
- Unit 3: Access, sharing and safety
- Unit 4: Getting organised.
This Moodle course is an openly licensed one and Sarah offered other institutions to adapt it. Kate has already expressed UCEM's interest in a Tweet.
Plagiarism in Distance Learning: Causes and measures for control presented by Ayona Silva-Fletcher and Clare Sansom was another presentation I really looked forward to since looking at the programme. In this they talked about a research project they have undertaken at UoL after seeing 274% increase in plagiarism cases at University of London World Wide during the past five years. In the study, they have contacted programme directors for UoL institutions with a survey to get an understanding of the plagiarism problem. In their presentation they presented plagiarism as a spectrum from clone, remix, find and replace, 404 error (made up references) to re-Tweets (too much of a chunk stuck in assignment). Some of the main reasons for plagiarism as revealed by this study were:
- Lack of knowledge (cultural background, insufficient engagement with materials, ignorance of self-plagiarism)
- Not enough time
- Pressure
All in all the event was a great learning opportunity giving me food for thought.

Supporting Student Success Event at Centre for Distance Education University of London
Yesterday, Fiona and I went to Supporting Student Success Event organised by the Centre for Distance Education, University of London which was really useful. The event had two parallel sessions and we attended different ones hoping to make the most of it.
In this blog post I am going to share my learning from Dr. Ormond Simpson's work.
Dr. Ormond Simpson presented a report about feedback from students with disabilities. I have not been able to locate the document online yet, but once I find it, I will link to the report in the blog post. The report was titled Disability the student voices: feedback from disabled students. The data for the report had been collected by sending an anonymous survey link to current students who have declared a disability. Though this does not reflect on views of students with disabilities who have dropped-out, it gives us a view to the struggles these students have to face in accessing learning.
The range of disabilities reported in this survey showed the varied individual needs and the need to support students for their specific needs. It was also the first-time I heard from a student with light-sensitivity as a disability.
Looking at some of the recommendations from the report, I can see that we, at UCEM, are already practicing some of these while there are other recommendations that we need to embed into our practice.
An important issue raised in the discussion was the ability to share information. Especially with GDPR coming into force it was reported that the details of disability declared to the university by the student during the application process does not get conveyed to the tutor on the course or the course directors. This has resulted in students not being offered the support they should have and students thinking that the university nor the lecturers cared about them.
I find it difficult to understand why GDPR or other data protection laws should affect the lawful use of declared disability data to support a student in a course. Perhaps we should seek consent to share the data with the tutor who is supporting student in the course. In my view, if a student has disclosed a special need, they would expect the course team to support them.
Unless the tutor is made aware, how would they "know" that this student has special needs especially at a distance. For example, if the university has special software to support special needs students but the tutor does not know that the student should be given a copy of this software it would affect the student's experience of learning. Alternatively the software could be made available to everyone, but that could be very costly and in fact unnecessary information for a large group of students.
It is easy to say XYZ is inhibiting us supporting student success but I believe we can find effective ways to overcome such barriers and research events like these bring the issues to light so that they can be addressed.

Creating videos using whiteboard apps
![]() |
| Writing on a whiteboard |
I then tried Doceri which did offer me the opportunity to create a free account without a time limit. You can select the resolution I selected the optimised one for iPad screen. It also allowed me to download my creation. However, need to pay if you want to remove the watermark. This is my Doceri creation - Using Doceri App on iPad Quick Demo.
Next I tried ShowMe. Out of the two apps I liked ShowMe but it does not allow you to download or privately save your creation with a free account. Here you can see my Demo of ShowMe app on iPad.
Despite the recommendations I received about Explain Everything I didn't feel I wanted to register and try out a tool that gave me only 14 days of free trial. On the other hand even though ShowMe did not allow me to download my creation I liked that app the best I think it is because I didn't like the frame used in Doceri at all.
There are so many tools out there - many apps. But you have to invest the time to go explore.
