I have noticed that when I read something is different than when I watch someone teaching it either through video or audio presentation. I noticed that when I watch videos of a specific topic, the presenter as if he/she is presenting a new meaning that I'm not aware of,( highlighting the key points) even though I read the same topic. So, do you feel the same way, that reading something isn't the same as seeing someone teaching it ? If so, how can I identify the key points in any scientific topic ?
Thanks in advance!
