The article "Online Education Remains Human Work" argues that it is and remains difficult to properly measure online learning outcomes. For example, peer-2-peer assessment does not seem to work well. Students do not look critically at their classmates' homework and are quick to give a pass. The conclusion "online education remains people work" is put down as something negative.
Online training is indeed human work, and that's a good thing! Perhaps you can use a test, online module or feedback to assess the knowledge gained. But if your goal is not just knowledge, but also change in attitude and behavior, nothing beats interaction! Interaction with someone who inspires you, gives you a pat on the back or a kick in the pants when you don't do your best. But also interaction with colleagues or other students is essential for the learning process. Can this be done online? Not through a self-study module or a recorded lecture. But by adding live online contact it is certainly possible!
There are so many tools that allow teachers to really teach online or where students can interact face2face. Effective live online sessions with real teachers and real students. No travel time but interaction. In this way online learning and teaching remains human work!
