  Textbooks frequently extol plate tectonics theory without questioning what
might be wrong with the theory or without discussing a competitive theory. How
can students be taught to challenge popular ideas when they are only presented
a one-sided view? In just a few pages, I describe more than a century of
geodynamic ideas. I review what is wrong with plate tectonics theory and with
Earth expansion theory, and describe my new Whole-Earth Decompression Dynamics
Theory, which unifies the two previous dominant theories in a self- consistent
manner. Along the way, I disclose details of what real science is all about,
details all too often absent in textbooks and classroom discussions. In these
few pages, I only touch on highlights and just part the curtain a bit so that
teachers might glimpse ways to bring to their students some of the richness and
excitement of discovery that becomes evident when one begins to question
prevailing, currently popular perceptions of our world.
