This paper deals with a modified weak Galerkin FEM for two-dimensional convection-diffusion problems with Dirichlet and physical conditions. The authors introduce a modified weak gradient and weak divergence, and a stabilization term without the need of being ``large enough'' constant-valued parameter. Some error estimates are presented. Three numerical examples are solved.
