It is unfortunate, but the reality is the kids that were just trying to slide along and were being passed as a courtesy in classes instead of based on actually deserving to graduate to the next grade we always be a lost cause because even if you put a student like that in a the best classroom in the world, the home environment where education is not considered important is still there. And your student is only in a school 6 or 7 hours a day 5 days of the week for about 9 months per year... but the rest of the time they have the parents that don't care... Which ones have the most influence? It isn't the school.The kids that are at failing schools are going to be disadvantaged in the same way they have in the past. The kids who have parents or guardians who have never taken an interest in their education are going to be disadvantaged in the same way they have in the past. The kids who don't pay attention in school or skip class are not going to start paying attention now, whether they have access to online learning or not.
The disadvantages have existed for some time. I guess they are just more noticeable now in this situation.
When trying to survive in times like this the best option is to see how to get the ones that are trying as much education as they can get, the others are already a lost cause and now isn't a good time to try and deal with it. Lord knows while it is a problem, it is one that can't be fixed in the best of times let alone right now.
