Tracy Roberts talks about PLEs with no “course” (in the traditional sense), and not “designing” courses (in the traditional sense, with outcomes/objectives... and I have to stop right there!
Outcomes/objectives are still there. Some are yours, or those of other influencers, mentors, facilitators, but most are the learners. You may not value or approve of the learner's desired outcomes but they may be personally very important. Nor does your desired outcome necessarily provide any rational or motivation for the learner's learning.
There is lots to discuss about scope, make-up, inclusion, relationships, connections, content in personal learning but I don't remember anyone saying that there weren't objectives and/or outcomes. There isn't any point to all of this learning if there aren't outcomes. Any learner implicitly knows this. It may be a surprise to find out what the objectives and outcomes actually are. But that's the power of reflection.
