  While Newtonian gravity is an adequate model for current geophysical
exploration, Einsteinian gravity, based on the connection between free fall and
warped time, has superseded Newtonian gravity as our best understanding of the
universe. Einsteinian gravity is fundamental to GPS navigation and is a useful
tool for geodesy. The Einstein-First Project is pioneering new curriculum
material that seeks to teach students, from ages 11 upwards, the Einsteinian
paradigm for gravity. By developing models, analogies and classroom activity
based learning, we have found that students are fascinated and easily cope with
concepts that adults, indoctrinated with Euclidean-Newtonian concepts, find
difficult and confusing. This paper reviews the Einstein-First program, its
methods and results of studies with students. We show that the majority of
students demonstrate improved conceptual understanding and improved attitude to
physics and that female students who enter the program with lower scores than
male students, increase their performance to be level with the male students.
