“…It also seems reasonable to conclude that learning about the solar system, like so many other areas of science, is a constructive process, one that appears to take place mainly through acts of personal and social cognition rather than direct transmission (Sharp, Bowker, & Merrick, 1997). Interestingly, while the solar system presents its own particular challenges for primary aged children, the same is also true of high school students (Suzuki, 1998;Taylor, Barker, & Jones, 2003;Trumper, 2001), teachers and trainees (Parker and Heywood, 1998;Spiliotopoulou & Ioannidis, 1996;Summers & Mant, 1995;Trumper, 2003), and members of the general public (Acker & Pecker, 1988;Durant, Evans, & Thomas, 1989;Lightman, Miller, & Leadbetter, 1987). The constructive nature of children learning about the solar system will, of course, be investigated further here, together with the notion of chaos in cognition.…”
