Pre-tests applied to 70 students of penultimate year showed a low level of grammar competence in topics as present perfect, tag questions, passive voice, used to and second conditional. Structured input grammar activities were incorporated in the experimental group of 35 students, while conventional strategies were applied in the control group of 35 individuals. There were 25 interventions of forty minutes in total to introduce input activities such as binary options, surveys, supplying information, matching, selecting alternatives, ordering, and ranking to facilitate the internalization of linguistic forms. The process culminated with a post-test to experimental and control group to compare and analyze the grades of both groups. The results demonstrated that a better average was achieved in the group to which structured input grammar activities were incorporated. In consequence, the incorporation of structured grammar activities has had significant impact on grammar competence of students.enLENGUA INGLESA - ENSEÑANZALENGUA INGLESA GRAMÁTICAADQUISICIÓN DE SEGUNDO LENGUAJEmasterThesis
