A Pivot (someone who works for Pivotal Labs) gave an excellent presentation on observational astronomy the other day. The presentation was so well done that I think it could easily inspire people to learn more about astronomy.
This is one of the questions I think about a lot. I truly believe that for education to be effective you need to tap in to intrinsic motivation. You can’t rely on extrinsic motivators like grades otherwise you run the risk of losing all motivation once the extrinsic motivators are removed.
Passion is a vague term, but it’s often to used to identify some subject or activity that people are strongly intrinsically motivated to do. You never hear people talk about passions rooted in the desire to get a good grade or a big bonus or the chance of promotion. People talk about being passionate about something because of the importance it plays in the world or how it makes them feel at fundamental level.
