Course Change Explorer: Accessibility Improvements

The detail comparison page within the Course Change Explorer now aligns with Web Content 2.2 (WCAG) Accessibility Guidelines.

How It Works

The Course Change Explorer provides users with a report from which to view the changes in an institution's courses between two catalogs. After selecting two data sets to compare, users are presented with lists noting the courses that changed, were dropped, or were added.

The Changed list reports all courses that have undergone a change in title, description, units, prerequisites, corequisites, lecture hours, lab hours, recommendations, terms offered, or grade basis. After selecting a course, the user can view a side-by-side comparison of the course details. In a third column, text added to Dataset 1 appears highlighted in blue, providing users with a visual cue as to what has changed. The text dropped from Data Set 1 is highlighted in pink.

CollegeSource has updated the COMPARE DETAIL page to align with Web Content 2.2 (WCAG) Accessibility Guidelines, which stipulate that color should not solely be used to convey differences in information to users. Now:

• Changes are announced to screenreader users, making it easier to understand the differences in data sets without relying on visual cues.
• Dropped text will include a horizontal line ("strikethrough") through it in addition to being highlighted pink.
• Added text will be bolded and highlighted in blue.

For further information, see Course Change Explorer. If users do not see changes right away to the Course Change Explorer, CollegeSource recommends clearing the browser cache.
