General Background I first became involved in the teaching of geometry about twenty years ago,when my department introduced an optional second year course on the geometry of plane curves,partly to redress the imbalance in the teaching of the subject。It Was mildly revolutionary,since it went back to an earlier sct of precepts where the differential and algebraic geometry of cuwes were pursued simultaneously,to their mutua!advantage.
