To improve student performance on the subjects studied, the fields of education and technology cannot be separated. Although technology has been used in Third Language Subject Education for a long time, student performance has been seen to decline from 2020 to 2021. In fact, the use of augmented reality (AR) multimedia technology continues to remain uncommon, particularly in third-language subjects at Universiti Teknologi MARA (UiTM). Due to the paucity of studies on the impact of using AR technology in the third language on student performance, this needs to be investigated. The use of AR in education and training can speed up instruction, be lightweight and portable, have clear content, and cost less to print. The purpose of this research is to determine how the use of AR-oriented multimedia technology affects student performance in third-language learning methods and lecturer roles. Data from questionnaires is collected using quantitative methods. SmartPLS 3.0 was used to analyse the data. A total of 387 UiTM students who took a third language course participated in the study. The analysis revealed that the use of multimedia had a significant impact on student performance, with the exception of the teaching strategy factor, which had no effect on student performance. Future proposals to broaden AR research into other areas of social science.
