Rating of previous courses

[olisand]

As a possible course participant, I want to see the rating of a previous course instance, so that I can decide if I want to take this course.

One issue that might arise from that could be "I want to compare the rating of a given topic trained by different nodes to choose which one to attend" and that will create unwanted competition.

Decoupling different factors that could contribute to course rating is not straightforward. This information may be misleading to the reader.

If required I would suggest breaking down rating into multiple scales or factors that could impact the perceived quality of the course.

Some factors include:

• Participants being selected vs first-come-first-served
• (Team of) Instructors
• Facility and equipment used (audio/video equipment, room configuration)
• Format (online, in-person, online + in-person, distributed (multi-site), ...)
• Accessibility (accents, captioning, platform for delivery ...)
• Quality or "Version" of training materials (they tend to improve after every event)

If the purpose is to share publicly the rating for a past training even, I'm not sure if decoupling is necessary. I'm imagining this would work like the reviews on Google Maps (or many other platforms):

Course title 4.20 ⭐⭐⭐⭐

My point, and I believe Olivier's above is that a single value can be misleading to the reader and lead to competition between nodes.

If the issue is a matter of UI, I would vouch for having a hover panel where the score would be shown split by different aspects. Motivation for the latter includes, providing a better understanding of what is impacting the score, rather than an opaque number.

A bit like Amazon score breakdowns, but with categories.

If defining scores by category is too challenging, I would find even the Amazon-like breakdown more useful than the aggregated one.
