“…The following studies are examples of AR applications as teaching aids for various purposes. First, there were studies conducted to see the suitability and sustainability of AR applications as an instructional tool to improve student's learning outcomes (e.g., Y. C. Chen, 2019;Hung et al, 2017;Shieu et al, 2019) and it is potential to assist laboratory activities or practical skills (e.g., Bazarov et al, 2017;Herlandy et al, 2019). In addition, there were also studies to see if AR applications are effective in reducing the cognitive load (e.g., Buchner & Zumbach, 2018;Sambodo et al, 2018), increasing students' positive feelings and other affective domains in learning the subject matters (e.g., Baloch et al, 2018;Hanafi et al, 2017;Sambodo et al, 2018).…”
