Because grammar has not been taught in many years, generations of teachers were never exposed to its direct instruction. Thus, even though many wish to teach it in their classrooms, they do not find that they have adequate knowledge on the subject. Unfortunately, this often perpetuates
linguistic stereotypes that can sometimes be discriminatory to speakers of
nonstandard language varieties. Another issue is that the curriculum for teachers is already very broad, especially in comparison to other college students, so requiring further courses for would-be teachers is rather unpopular. The same problem exists in the K-12 classroom which already have difficult time constraints on their current curriculum. To add grammar to an already full curriculum is extremely difficult. == Benefits ==
