Having an up-to-date and user-friendly website is essential for any college, especially during a pandemic. Imagine that Im the chair of the Web Communications Committee that is looking at the information on a college website provided to students about their current learning options. The problem in this situation is that we are not sure that students are able to easily find the information they need to stay on their degree paths, so Im "hiring" you, as a technical communication student, to establish what information is currently available, in what format that information is provided (videos, documents, etc), how accessible it is, and then propose recommendations to the committee regarding what changes should be made. Issues to take into consideration: what information students need to know regarding their degree programs, what courses are offered in what delivery mode, how students access information, how easy it is to navigate the website and find the needed information, and how this college compares with other institutions in the information we provided to students.
