Hi @AFSRetire, glad to see you're interested in Academy's framework! (For those who don't know, I am the sole Web Designer/Developer over on Academy). After taking a look at our site, app and learning experiences, this is how I would look at modeling your idea off of Academy.
The HubSpot Academy team has a few different ways in which we deliver/host our trainings online.
Website:
First, is our website. academy.hubspot.com currently is a place in which we host training which we want to help bring to the world (and use to generate traffic), as well as be a place for which we can innovate and try new ideas. As far as content goes on here, you'll see a few:
- Master Classes. See them here: http://academy.hubspot.com/mas
ter-class - HubSpot Software Certification Classes (These are also in the Academy app, which I'll talk about in a minute). You can see them here: http://academy.hubspot.com/buy
er-personas-videos-training - Modular Training Courses, see them here: http://academy.hubspot.com/mod
ules/optimizing-website
Modular Training:
I was actually the only person who developed/coded on this interface so I can speak a lot on how it works and what it does. To start, Modular Training was built to be extremely lean, because we needed it to run a lot of custom javascript, so this is all the actual layout is.
We are utilizing the Flex Column module pretty heavily. What this module allows you to do is load prebuilt modules into the template from the edit page interface. This allows me to put up guardrails of design, so everything looks consistent, but still allows our professors to create a module according to their lesson plans. When the page loads, all of the modules are pushed into an array, so that we can access them as a group when we append it into the side tabs. Since the custom modules only hold the information that shows in the panel, we need to pull data like the name, icon, and content type from the module to print onto the navigation. The we utilized a custom tabber design that I created to allow us to tab through the module.Learning Center:
Secondly, we have our own Academy app which we developed here in house. This currently is the place in which all of our certification courses live. There are benefits to developing this type of in-app system because you can better track users who sign up, their progress (course/class compeltion rates), and their likelihood of returning. And lastly, if you're also a software company, you can tie their behavior with educational content to their app usage, retention, and other metrics that matter to your company.
Hope this helps you out! Let me know if you have any other questions, or if you want any more explanations
