It is my view that online teaching should always be informed by infrastructure limitations of our learning management systems (LMS) and our institutions. By infrastructure limitations, I mean both the physical infrastructure, as in the local and cloud servers that host our LMS and the physical connection of our campus to the internet, as well as the digital infrastructure of the LMS itself, or the availability of specific features of the LMS under the strain of multiple users under less than ideal conditions. To this end, this piece will focus on structural considerations where online teaching is concerned.
I will address concerns with physical infrastructure first. Most institutions have a sufficiently robust infrastructure to meet the needs of both students and faculty. In fact, most institutions rarely exceed the capacity provided by their local internet connections. As an example, the closest my institution has come to exceeding its capacity for internet connectivity was during the recent release of major updates to the first-person shooter, Call of Duty: Warzone, and the MMORPG Division 2. With students and faculty away from campus, and not using the institution’s connection, there is little risk to exceeding the institution’s available capacity.
Not every institution has a robust internet connection: many rural or underfunded institutions may not have sufficient capacity to maintain stable connectivity to their web-hosted portals. Library websites, institutional websites, and other crucial forms of information made available to students and faculty through institutional web portals may become unavailable during times of increased load. While this does not directly impact student use of online learning and LMS, it does impact student ability to access those LMS and online resources should they not have the resources themselves bookmarked.
These issues can be resolved relatively quickly under normal conditions: IT can establish alternate portals to ensure availability or can take actions to limit the strain on web portals by through other technological remedies. However, these are not normal conditions. The speed at which our IT support personnel can respond to overloaded or crashed websites is dependent upon the availability of those personnel, and their ability to address a problem remotely as many may not be on campus during the pandemic. Further, in a remote work situation, with IT Help Desk lines forwarded to personal or home phones, IT support may be quickly overloaded with requests to address crashed websites or portals and may be unable to respond with their typical speed.
As someone who has worked with and for campus information technology services as a faculty and an employee, here are some recommendations to minimize the strain on IT personnel.
- Reach out to your senior most IT personnel to determine the best means to submit help requests in the event of a remote work situation. Standard mechanisms may be inadequate or insufficient to handle a large volume of requests.
- Reach out to your senior most IT personnel to determine the appropriate information to submit in the event of outage. Not all information will be valuable to address the issue and providing the most helpful information to your IT personnel can speed their response to your issue.
- Be patient with your IT personnel as they may be experiencing increased call volume. That was a joke, but one that is grounded in reality: your IT help center and help desks may be overloaded in the event of a major outage.
- Your IT personnel may not be able to address every issue that arises with online teaching or with your LMS. Some issues must be outsourced to the LMS providers, particularly if the LMS operates on a software-as-a-service model.
- If you have concerns about your specific LMS installation, consult the LMS help pages. As an example, for Blackboard, consult blackboard.com for specific advice.
The other aspect of infrastructure concerns that educators should bear in mind are the infrastructure limitations of the LMS itself. To understand this point, we have to take a walk through the architecture of a LMS, Blackboard in this example. That said, it needs to be stressed that each of LMS has different attributes and features which means that the infrastructures have different kinds of limitations and should be considered differently.
