The primary aim of the study was to investigate the effectiveness of the grammar translation method in teaching reading and writing, assessing whether this technique leads to better learning results compared to conventional teaching methods. Utilizing a quasi-experimental method, the study revealed that there was a significant difference in the achievements of students in reading and writing in their pretest and posttest in the class. The findings suggested that employing the grammar translation method enhanced students' proficiency in reading and writing. Therefore, employing this approach might produce better outcomes than solely depending on the second language method, thereby enhancing students' academic performance. The results indicated that the grammar translation method was effective in teaching Reading and Writing to Technical Vocational Livelihood students, showing positive academic results. Hence, it was recommended to apply the method to additional Reading and Writing topics beyond those examined in the study. Moreover, future researchers were encouraged to adopt the methodology and investigate its effects not only academically but also across social, psychological, and physical domains.
