We analyze nonconforming finite element approximations of stream-
line-diffusion type for solving convection-diffusion problems. Both the
theoretical and numerical investigations show that additional jump
terms have to be added in the nonconforming case in order to get
the same O(h k+1=2 ) order of convergence in L 2 as in the conforming
case for convection dominated problems. A rigorous error analysis
supported by numerical experiments is given.
