The increasing technological development of computers, tablets and smartphones has enabled a rapid increase in the adoption of mobile technology for language teaching and learning, and numerous applications that provide easy access for any learner without limitations of place and time have been developed. This paper shows the study of grammatical treatment using corrective feedback supported by mobile applications. The study subjects were first-level students of the language institute, where a control and experimental study was carried out. The experimental group was evaluated with paper-based assessments and the control group with the Canvas mobile application. Subsequently, a statistical analysis was performed for data analysis. The results show that there was a 4.9% improvement in the grades of students who used the application and received corrective feedback. [For the full proceedings, see ED639391.]
