Most kids need the structure of the in-person school to be motivated to learn day by day, over a long period. If you give them a playlist and a bunch of problems to solve they will feel overwhelmed and alone.
The High School Survey of Student Engagement finds that 66% of high school students are bored in class every day. Seventeen percent say they're bored in every class every day. Two percent claim they're never bored. 82% say the material isn't interesting; 41% that it isn't relevant[1]. Middle school students are bored 36% of the time during schoolwork, versus 17% for other activities.
