    Some recent work indicates that more than 50% of today's college
freshmen
are operating on the concrete level - they do not abstract.  Work done by
Jensen,
et al., indicates that many *never* achieve the abstract operations stage.

    Many - if not most - of my college astronomy students are unable to form
a
mental picture of the relationship between the earth, sun and moon.
