Since augmented reality (AR) has been increasingly applied in education recently, the investigation of students' learning experiences with AR could be helpful for educators to implement AR learning. With a quantitative survey using three questionnaires, this study explored the relationships among 153 students' perceived cognitive load, motivation, and attitudes of perceived control, perceived usefulness, behaviour of learning, and behaviour of AR learning, when they engaged in an AR book reading activity. The results indicated that, in general, the students perceived less cognitive load, stronger motivation, and more positive attitudes towards the experiences when reading an AR book. However, dissimilar to past studies, the perceptions of low level cognitive load cannot be guaranteed to lead to positive intentions to learn. Interestingly, motivation mediated the relationships between the students' perceived cognitive load and behavioural intention to learn. Only when the students' perceptions of motivational factors such as attention or confidence were significant did the perceived usefulness and cognitive load play a role in their behavioural intentions to take part in future AR learning. The findings of this study may provide insights for future AR-related studies to explore the role of cognitive load in learning performance with consideration of motivational factors.
Introduction Augmented reality learningAccording to the Horizon Report by the New Media Consortium (NMC), augmented reality (AR) represents a large amount of the investment undertaken by the technology industry and is indicated as one of the important developments taking place over the next few years (Johnson et al., 2016). Following the trend of technology development, several educational studies have endeavored to explore what role AR, a technique of blending virtual information with the physical environment for presentation in real time, plays in learning. The findings of these studies have mostly indicated the advantages of AR technology, and have further addressed the positive influences of AR on learning effectiveness in fields such as science and engineering learning (e.g., Behzadan & Kamat, 2013;Chiang, Yang, & Hwang, 2014;Lu & Liu, 2015;Sommerauer & Müller, 2014) and medical science (e.g., Lapeer et al., 2014;Ferrer-Torregrosa, Torralba, Jimenez, García, & Barcia, 2015). Relatively few studies have probed how AR technology integrated with paper books (called AR books) can assist students' reading. In 2011, Abas and Zaman reported that the AR book system with scaffolding models they developed could help students to read a story book, particularly those with low reading ability. Similarly, in Vate-U-Lan's study (2012), it was found that the students' comprehension of the content of the book was enhanced by using AR technology. A recent study also indicated that, in the AR learning context, children's imagination regarding the content of AR books could be extended (Cheng & Tsai, 2014). Since the role of AR in reading has been highlighted by...
