Rather than starting with the solution, students should first be taught to research and investigate the problem.
I’ve loved electronics ever since I was a kid. In 6th grade, after saving up for five years, I built a PC that was better than any computer I could find. Throughout middle school, I tinkered with wiring and welding and electronics (as you can see by the piles of unused Arduino boards and leftover electronics in my room). It was easy to make something for myself—an awesome PC—but making something other people wanted wasn’t as easy.
