I think we should need to introduce some educational content in which people can show thier education & experience and can get some online certification from thier steem teachers, who can helps in their practical life too. (Especially for developers and freelancers)

For this as you write that steem learning challenge gose free style, it would be a free style and also easy for everyone.

And we can develop a site in which we can store the record of our participants and their certifications.

However it's just an clue of my idea, i will write in detail in my post, Have a nice day. Thank you so much for the new update.
