Interactive 3D model of Solar System, Planets and Night Sky: "Welcome to Solar System Scope space traveller, SSS means Astronomy for Everybody. Whether you are a student, astronomy fan or an accidental browser, you are most welcome to play with our user-friendly application. It's full of space-art graphics, has easy-to-use interface with various settings and offers interesting information. SSS will illustrate you real-time celestial positions with planets and constellations moving over the night sky. But I can see you're not just a passive spectator - and that's good, because you can actively change parameters for a better understanding of happenings in our Solar System and the Universe." in www.solarsystemscope.com
All teachers of programming find that their results display a 'double hump'. It is as if there are two populations: those who can [program], and those who cannot [program], each with its own independent bell curve. Almost all research into programming teaching and learning have concentrated on teaching: change the language, change the application area, use an IDE and work on motivation. None of it works, and the double hump persists. We have a test which picks out the population that can program, before the course begins. We can pick apart the double hump. You probably don't believe this, but you will after you hear the talk. We don't know exactly how/why it works, but we have some good theories.
