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).
Functional Objective
Given a Web page that may contain images, but must contain text, learners will press two keys to enlarge page content.
Outcome Measure
Learners will open a novel Web page and, without instruction or prompting, enlarge its contents.
Component Skills To Be Taught
Pressing Keys
Learners will:
- 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
Learners will:
- follow a multi-step chain of behaviors
- identify the start- and end points of the behavior chain
- repeat the behavior chain
Prerequisites
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:
- IBM-compatible
- attached to a monitor and a keyboard or equivalent assistive-technology
- using Internet Explorer as the default Web browser
- connected to the Internet
Notes:
- 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.
