Basics of Inclusive Design for Online Education

classificações

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 5: Uncovered Topics, Resources & Review

This final week of the course will cover topics not covered in earlier lessons: keyboard accessibility, color contrast and the accessibility of Learning Management Systems (LMS). The assignment will ask you to use a resource we have covered and one discovered by you to address one of a number of accessibility scenarios.

This is the fifth and last module of this MOOC.

We've covered a variety of issues about making courses accessible and inclusive.

But with just five weeks, our treatment of this topic is by no means comprehensive.

We try to touch upon some key issues that often create obstacles for

students with disabilities and if addressed

can make a significant improvement in the inclusiveness of a course.

In this last week's lessons, we will briefly cover some topics we have not

covered, including keyboard accessibility, color contrast and

the accessibility of learning management systems.

We'll conclude this week's lessons with resources that will allow you to go

further into creating inclusive courses for your students.

Our assessment for this module will ask you to use these resources to research and

propose solutions to situations that inhibit accessibility.

Let's look now at keyboard accessibility, a topic we have covered only briefly.

Keyboard accessibility means the ability to navigate and

operate the controls of an application or web page using only the keyboard.

Keyboard navigation is crucial for individuals who do not have the dexterity

to use a mouse and for individuals who are blind.

There is no tool or automated method for

testing the keyboard accessibility of an application or web page.

This is a test that needs to be conducted by hand.

I'll add that automated tools such as achecker which we'll talk more about later

can detect the use of JavaScript on a web page and warn you to check for problems,

but it cannot determine if a particular page or script is keyboard accessible.

Problems with keyboard accessibility are more likely to occur on websites that use

JavaScript for creating controls and user input on a page.

Problems are also more likely to occur with proprietary technologies,

such as Flash or complex widgets such as media players.

To check the keyboard accessibility of a web page or application, put your

mouse to the side or disconnect it and use the keyboard to navigate and interact.

First, try tabbing through the page on screen.

On a web page, can access all the links, navigation and controls,

such as form elements, search, for example?

Is the page arranged logically for a keyboard user?

In other words, do you progress through the page in a logical manner or

do you jump from the top of the page to the bottom and

then perhaps back to the middle?

Is there a visually perceptual keyboard focus?

In other words,

can we tell our place on a page when we move through it using the tab?

Web pages and applications that follow best practices present a clearly

visible border or other visual cue, such as a change in foreground or

background color, around or within the current object of focus.

One of the better implementations of this is on the WebAIM site,

which I am now showing.

WebAIM is an organization that provides a wealth of resources around web and

document accessibility.

As I tab through the WebAIM home page, every link or

control provides visual feedback as it receives keyboard focus.

The clickable image at top left and the text space navigation on the right and

the search field present a distinct new border as they receive keyboard focus.

Some items display a red font upon focus providing additional visual feedback.

Note that I can also enter text into the search field and tab search button and

press Enter to initiate the search.

Pressing Enter on any of the navigation elements or

other links will also activate that link, the same as a mouse click.

One particularly useful feature is a skip to main content link at the top left

of a page, which is the first item that a keyboard user encounters.

This link allows a user to jump past the branding and

navigation element in the page directly to the main content.

In this case, I am brought directly to the results for

my previous search on the term keyboard.

A keyboard user with vision should be able to easily determine their location on

the page and interact with the links, and controls on the page.

A blind user operating a screen reader would also be able to interact and

navigate the page, although their feedback would provided by the screen reader audio

and not visual feedback.

Note that Mac OS users may need to turn on keyboard functionality in their browser

through preferences within Safari or with Apple system preferences for Firefox.

The link displayed here and also in the resource section of this module will point

you to an article which provides step by step instructions on this issue.

For an example from the other end of the accessibility spectrum,

I'll display the homepage of The Daily Beast.

As I tab through the page, I know I'm progressing through the page,

because the status bar,

bottom left is showing me changing URLs of the different links I'm landing on.

However, I have no visual feedback that I am moving through the page.

You can conduct this type of test yourself within any application or web page.

If you could conduct only one test of accessibility, a test for

keyboard accessibility might be the most revealing.

That's because keyboard accessibility is required for

both screenreader users and those unable to operate a mouse.

A lack of keyboard accessibility indicates a fundamentally inaccessible page or

application.

In the next video, we'll talk about the last unaddressed issue on our agenda for

this lesson.

Poor color contrast.
