I've been considering what interested my 11-year-old {female} self about programming. The question keeps popping up, and the only answers I've seen are so vague that I feel something of a moral obligation to offer my own specific insight.
To put my experience in context, I didn't know a single soul interested in programming IRL. So the only way I could have come to it is from a deeply genuine place.
In my adult life, I've heard many men talk about their excitement for coding/programming at a young age, and it is almost always about the love of simply building things. Because building is fun.
Unfortunately, my experience could not have been more different. Reflecting on my thought processes at that age, I remember it being entirely about 2 things:
1. Expression. Nothing could have sounded more dull than building aimlessly-- I wanted to DESIGN. (My definition of this being "carrying out a specific communicative purpose through look and function.") I wanted to make a website that demonstrated my tastes and values to my friends. (Which is likely why I went straight to websites and not desktop software.)
2. Social dynamics. Similar but different to the aforementioned point, I wanted to actually affect other people with what I was making. As a young girl, that typically meant impressing potential friends and boyfriends. I had a poetry site at one point. I made sites for a fake band my girl friends and I talked about forming. I had tons of blogs. I really should have segued into games at that time, as that would have fallen in the same category, but sadly I did not.
That said-- while I know every human being is different, I was what you'd consider a "girly girl." So I believe the difference between myself and a young boy was quite pronounced in a stereotypically feminine direction-- which is where one should be investigating a subject like this, in my opinion.
