I think it depends on some factors. I work from home so my son could ask help from me when he needs to clarify some of his lessons in school. He also has access to devices and fast internet. He could search for things he doesn't fully understand as well. I would say that for him, remote learning is effective. I've seen some of his classmates struggle. Their parents are out working, so they sometimes call my son for help or chat in their group chat to ask help in assignments. Also, children have different learning curves. Some might do better with face-to-face setup.
