AR offers disabled persons the possibility to replace or repair non-existent senses. Visual messages can be transmitted to individuals with hearing problems to assist them in detecting missing audio signals, or aural signals to blind persons to assist them in finding their way/unfamiliar visual events.
AR is expected to have a key role in sectors like education. A paper recently published in Education Sciences explored the future of AR in science teaching and learning based on the preschool and primary teacher students’ views.
The teacher students as prospective educators acknowledged the significant benefits of AR integration for their future students, specifically emphasizing the AR-enhanced materials’ potential in science classrooms to have positive cognitive and motivational effects. They also believed that AR integration would increase their students’ active engagement and interest.
The finding was consistent with earlier studies which reported that AR enhances students’ engagement and interest based on the views of in-service primary and secondary teachers. The teacher students recognized that their involvement in AR-enhanced material development heightened their engagement and interest in the course, expanded their knowledge, and fostered a sense of innovation.
Common benefits of AR identified by teacher students for themselves and their future students include enhanced engagement and knowledge acquisition. This was a promising outcome as recognizing the technology’s effectiveness could encourage teacher students to incorporate AR into their teaching practices. The teacher students perceived that applications like ARTutor application, utilized for AR-enhanced material creation, were easy to use for themselves as creators and their future students as readers.
This finding was consistent with literature which states that such applications can be easily used by teachers to create augmentations and by students to view the digital content. Moreover, the teacher students also identified opportunities for their future students, mostly in upper primary school, in using ARTutor as creators/co-creators.
Lastly, the teacher students acknowledged AR integration challenges related to technical difficulties in the classroom, the significant amount of time required for AR-enhanced material creation, and such materials’ potential to divert the attention of students from learning objectives. These challenges can be addressed by improving the training courses dealing with these issues and offering greater support to teachers in practice to enable them to mitigate these issues.
In conclusion, AR is poised to revolutionize how we interact with the world, driven by advancements in hardware, artificial intelligence, and 5G. While challenges like privacy and content standardization persist, the potential benefits for individuals and society are immense.
