The purpose of this study was to investigate the impact of augmented reality applications in the Diploma Program Educational Technology course on students' academic achievement and attitudes towards these applications. A quasi-experimental design with a pretest-posttest was utilized on an experimental group and a control group. In addition, the experimental group completed the attitude scale prior to and after the implementation of the AR instructional program. The participants consisted of 99 male and female students from two sections the mentioned course. Through random assignment, the experimental group (50 students) received instruction using AR applications, while the control group (49 students) was taught using traditional methods. The collected data were analyzed statistically using ANCOVA, and the results showed statistically significant differences at a significance level of 0.05 (a) between the experimental and control groups in the achievement test, indicating a positive effect of using AR applications in teaching in favor of the experimental group. Additionally, statistically significant differences were found in the attitude scale for the experimental group, favoring the post-application phase, indicating positive attitudes towards AR applications. The study recommends the integration of AR applications in university courses for Diploma students according to their specializations. Furthermore, it recommends conducting training courses for Diploma students and educators to bridge the gap between theoretical knowledge and practical application of technological tools in teaching.
