As an expert and parent one thing I noted during this period of time, in one hand the approach we as a parent use seems borrowing for children, which creates low level of interest among children. In other hand, by nature children themselves are willing to do something while other child is in his/her side for competition. Importantly, the focus of most parent is to tell the child what they want them to do rather than letting them to explore by themselves, which is not theoretically. So, these things become a stressful situation for children.
There are several psychological impacts on childern when they ae learning from home. As, they are not been able to spent time with their teachers much, their learning is not getting effective and they are also feeling!
This is a very difficult issue, especially for primary school children. They are dominated by external motivation to learn, they need constant emotional contact with an adult who approves of their attitude to learning tasks. They also like to show success to classmates. Therefore, when schools operate only online, their motivation to study decreases. (Sorry for the bad English)
First, by virtue of the different contexts, home & school, they 'energy' is different. School is associated with strict rules in relation to time keeping, etc. that must be strictly adhered to. Home, on the other hand, it associated more with informal activities. Covid-19 has changed all this & this change necessitated that learners change accordingly. Thus the mental/ psychological impact or adjustment.
Second, not all children have access to tools and gadget to enable their smooth transition, from the "actual classroom" to a "virtual" one. The result is such that the learning achievements are not met at the same level by all learners. This unequal access is likely to have some psychological impact on learners, upon realising this divide.
Third, the potential psychological impact on learners who do not have parents/ adults to can assist them, for various reasons. For example in RSA, there is a phenomenon of 'child-headed households'. In other cases, it could be that parents or adults are not equipped, either technologically, financially or otherwise.
All these are likely to impact learner's academic performances.
