My experience with helping seniors ranges from one extreme to the other.
One 95-year-old woman who had never used a computer was computer literate within an hour, exclaiming "oh, look at what I can DO!"
Another scolded me for encouraging her to get a smartphone. "It took me all night to learn to use it".
But others just say "I just don't get it".
So how do we learn?
I faced a block when I needed to minor in history in graduate school. I hated history and thought I had a poor memory.
The History Department head offered to help me. Simply, he asked me to memorize 50 dates. That's all. That simple exercise gave me the "hooks" I needed to pull everything together. I never had to work at memorizing dates again. I went to top of the department's classes.
So it is selective memory you need. Your brain will automatically connect and remember if you give it a few dozen mental landmarks.
Tap or click for a site to get grounded if you are new at computers.
Or tap or click for a $.99 ebook on how to use your brain to learn.
Another highly effective way to learn to use a computer is to sit alongside someone else who knows how. I learned programming that way.
