When gathering data, a questionnaire is utilized as a research tool and distributed. This study looks at the mistakes that students made on the pre-test. As the preferred sampling technique, judgmental sampling is used. The investigator then uses the Cognitive Code Method and Mobile Assisted Language Learning to combine pedagogical intervention after classifying and tabulating the errors. Ultimately, a post-test that acted as an achievement exam is used to evaluate the impact of the instructional intervention and the performance gap between the experimental group and the control group.
