Mandarin is one of the seven third-language courses offered in UiTM and has the largest number of students among the seven languages. In certain faculties at UiTM, the results of the Mandarin test were poorer. Hence, this project was conducted to improve the results of Basic Mandarin 1 in certain faculties in UiTM. The study was conducted at UiTM Selangor, comprising of Shah Alam, Puncak Perdana and Puncak Alam campuses. Based on the analysis from the Student Information Management System (SIMS) at UiTM, the score of the Basic Mandarin 1 writing test was found to be the lowest compared to the scores of the listening test, reading test and language project. In addition, the percentage of students who received Grade A in the faculties for the study was less than 15% while the number of students who received Grade C was over 30%. Therefore, the e-Kosa Kata app using Microsoft Sway was developed to help students memorize and remember vocabulary through digital devices. A questionnaire was also distributed to obtain students’ feedback on the effectiveness of the e-Kosa Kata. A total of 228 respondents from four selected faculties participated in the study. The findings showed that there was an increase in writing test scores and the percentage of students who received Grade A after using e-Kosa Kata. Additionally, the e-Kosa Kata app also benefits the environment, students, lecturers, departments and university. The app has the potential to be widely used among students as well as the general public who are interested in learning basic Mandarin
