Many people need to enlarge Web pages to better see information. People with cognitive disabilities often require larger text sizes to better comprehend information as well.
To develop a best practice for teaching a Web page (text) enlargement skill, I will conduct in-person teaching to groups of people with cognitive disabilities. Specifically, I intend to teach people to use a keyboard with a Web browser to enlarge Web pages. Many browsers will enlarge pages in response to the pressing of two keys: the plus key and the Control key (IBM) / Command key (Mac).
Given a Web page that may contain images, but must contain text, learners will press two keys to enlarge page content.
Learners will open a novel Web page and, without instruction or prompting, enlarge its contents.
Component Skills To Be Taught
- locate the correct keys (2)
- hold-down one key for at least 3 seconds with sufficient force to be recognized by the computer
- hold down the one key and tap the other key by pressing it with sufficient force to be recognized by the computer, and immediately releasing it
Completing Sequential Steps
- follow a multi-step chain of behaviors
- identify the start- and end points of the behavior chain
- repeat the behavior chain
Learners must be able to:
- respond to textual-, auditory- and/or video-based instruction
- press keys with their fingers or with equivalent assistive-technology
- press the correct keys only
- open a Web page with Internet Explorer
Computers must be:
- attached to a monitor and a keyboard or equivalent assistive-technology
- using Internet Explorer as the default Web browser
- connected to the Internet
- This post is the second in a series about Teaching Web Page (Text) Enlargement. Next up: “Google Video Teaches How To Make Text Bigger”.
- On the future Clear Helper Web Site, I intend to teach all skills via the Web itself.
- Please post a comment with any suggestions.
