Various interactive and innovative applications generated by Augmented Reality (AR) technology have given great potentials in different learning subjects and specifically in STEM (science, technology, engineering, and mathematics) education. Nevertheless, previous studies regarding AR integration inside classrooms have shown that as a valuable technology for students' motivation and participation alone cannot automatically lead to its successful use. This study focuses on teaching and learning mathematics by taking advantage of AR technology to visualize several problems and let users interact with its contents. In this perspective, the purpose of this study is to present an instructional approach by which competencies of seventy-eight (n=78) trainee instructional media designers with a successful and appropriate integration of AR technology inside classroom contexts using HP Reveal and Blippar. In favor of designing and assessing AR applications for mathematics, the instructional media designers have shown satisfactory performance and user experience. Specifically, all AR applications seemed that enable the representation of intuitive learning scenarios and increased greatly users' interactive experience, thus encouraging their achievements and outcomes. This study contributes to the most relevant practices of teaching and learning for mathematics with the integration of AR applications which are developed by trainee instructional media designers to support successfully the educational process with several examples to be visualized by merging physical ("target tracking") with digital features and objects.
