This talk is an overview of the discontinous Galerkin (DG) method as a time-stepping procedure for classical and fractional diffusion problems. After motivating the definition of the procedure, I outline its implementation and then illustrate key properties with simple, scalar ODEs and fractional ODEs.  I then describe results for classical and fractional diffusion problems in 1D, and sketch an explanation for the observed superconvergence behaviour.
