there's no evidence on scientific pedagogic literature that "analog ways" are better than digital when you control variables like "your kid being able to open a tab to watch a non-related Youtube video". you can't use your sample of 10 kids to say anything, nor use poor journalism done into the topic, which cites single research with less than thousand participants and bias from the author by other scientists on the field

no meta-analysis done into this topic could conclude anything beyond the digital medium being a bit more efficient on reading speed. and these studies do not account when comparing one way to the other on the plethora of ways a digital medium can expand knowledge (videos, gifs, images, interactive visualizations and so on)
