The greatest obstacle to effective remote learning, as per this section, is distraction. Obviously, this particular course was created to address concerns during the COVID pandemic. However, what I (and most teachers that I work with) learned from remote learning during COVID, is that it is largely ineffective. I disagree entirely with the assertion that this is the education of the future. Rather, this is another example of industry selling technology for the sake of technology, and getting fat off of taxpayers dime, regardless of indicators of significantly lower performance and retention during remote learning.
