GEOTREX GEOTREX is a project conceived by Ben Church, who has taught the WJEC Geology GCSE, AS and A2 specifications at Monmouth Comprehensive School since 1989.

GEOTREX aims to facilitate networking, leading to the sharing of our best resources and ideas, making teaching and learning more effective for everyone.
