This course provides instruction and strategies to support you in developing a course that is inclusive to students with a wide range of abilities, including students with disabilities. We cover effective practices to increase inclusion and avoid some of the common accessibility issues that can arise in an online course. In particular, Basics of Inclusive Design Online covers course organization, the accessibility of Microsoft Office and PDF documents, making course instruction pages accessible, captioning of videos, making images accessible, and designing for learning differences. We also discuss how inclusive course materials can help all students, including students without disabilities. This course will appeal to those who want both a broad overview of the range of accessibility considerations and also a step-by-step guide of how to check documents for accessibility, caption a video, or prepare course content for non-visual users.

Week 2: Accessible Documents
Following a review of online accessibility issues, in this week we will explain the steps to create and remediate course documents in MS Word, PowerPoint, and Adobe PDF documents. The assignment will provide you with an opportunity to apply these skills to actual documents.

PDF files are a common way of providing course content to your students.
An accessible PDF file is a file that contains structure, text and
alt text that can be communicated to assistive technology like screen readers.
If the assistive technology can tell that this information is there,
it can convey the content to your students.
In this video I'm going to show you how to recognize when there is real text in your
existing PDF files and not just images of text.
And I'll introduce to PDF tags and alt text.
You'll probably find some of these ideas familiar from our previous video on making
accessible word documents.
Then I'll show you how to create accessible PDF files and
share some step-by-step guides with you.
And last but not least, I'll show you how to check for
accessibility of the PDF files you create.
Some PDF files are image only files containing scans or
images of the original content.
These types of PDF files are inaccessible for
those using assistive technologies, as there is no structure, alt text or
computer text for the assistive device to convey.
To check to see if a PDF is image only,
you can try to select or highlight the text in the documents.
Notice in this example of an image only PDF, my attempts to select the text
results in just drawing a highlight box rather than highlighting lines of text.
Here is a PDF that includes real text not an image of text.
When I try to highlight the text I'm able to highlight individual words, lines and
entire paragraphs of text.
If I wanted to I could copy and paste this text into a Word document or
an email and it would recognized as text by the other software.
Image-only pdf files can be difficult for
all of your students as scanned text can be visually difficult to read and
prevents the use of commonly used tools like Adobe's Read Aloud feature.
We recommend avoiding the use of image-only pdf files in your courses.
For a PDF to be accessible it needs to have real computer text,
not an image of text.
It needs structure indicated by tags, we'll talk more about tags in just
a moment, and it also needs to have alt text for any images within the documents.
If your PDF file contains real computer text,
not just an image of text, you can allow assistive devices to recognize this text
by adding structure through the use of tags.
Tags are similar to Styles in Microsoft Word and
for those of you familiar with HTML, PDF tags are similar to HTML tags.
It's a way of labelling the components of your file content as headings,
text, tables, figures and so on.
It also provides the ordering for
how content can be presented to those using screen readers.
Content that is tagged as an image can also be given alt text,
a concise description of the relevant information conveyed by the image.
By adding tags and alt text to your PDF file,
assistive devices can convey all of the content to the user.
If you generate a PDF from a Microsoft Word 2010 or 2013 document,
you can transfer a use of styles and alt text when you generate a PDF file.
You need to make sure you have some specific options selected
when you generate the PDF file.
Specifically, create bookmarks using headings and
document structured tags for accessibility.
With these options selected your use of styles will convert to tags and
your alt texts will carry over into the PDF file.
You can find step-by-step instructions for generating tagged PDF files for
Microsoft Word 2010 or 2013 in the resources for this module.
If you do not have access to the original document that a PDF file was generated
from, but still need to make the PDF file accessible, you'll have to add tags and
alt text directly to the PDF file using Adobe Acrobat Pro or
equivalent Adobe products.
You can find step-by-step instructions for tagging and
adding alt text to a PDF file in the resources for this module.
If you use a Mac, and would like to make an accessible PDF
from the content created in Word for Mac, your styles and
alt texts will not transfer to a PDF file, and will not result in an accessible PDF.
You will need to generate a PDF file from your Word document and
then add tags and alt text directly to the PDF file using Adobe Acrobat Pro or
equivalent Adobe product.
You can use the same step by step instructions for tagging, and
adding alt text to a PDF available in the resources for this module.
Adobe Acrobat products contain an accessibility checker
to help ensure that you have accessibility information in place for your documents.
To run the accessibility checker in Adobe Acrobat Pro,
select the accessibility tool, full check, then start checking.
A list of issues will appear on the left.
In this document we have not yet added tags, or alt text, so
there are many issues found.
In this second document, we have added our tags and alt texts so no issues are found.
You can also check that the accessibility information is available to assistive
technology by seeing if you can listen to your content with a screen reader.
There are many screen readers available,
including free options like NVDA for PCs and Voiceover for Mac.
Remember to check out the resources available in this module for step-by-step
guides and tutorials for making accessible PDF files from Word documents.
