The objective of this study was to determine the usefulness of augmented reality (AR) in teaching. An experiment was conducted to examine children's learning performances, which included the number of errors they made, their ability to remember the content of what they had read and their satisfaction with the three types of teaching materials, including a picture book, physical interactions and an AR graphic book. The three teaching materials were aimed to respectively demonstrate the characteristics of six bacteria with 2D graphics, 3D physical objects, and 3D virtual objects. Seventy-two fifth-grade children were randomly selected to participate in the study, and they were divided into three groups, each of which used the assigned teaching material to learn the name of the six different bacteria in intervals of 1, 2 and 3 min. Results showed that the AR graphic book offers a practical and hands-on way for children to explore and learn about the bacteria. Follow-up interviews indicated that the children liked the AR graphic book the most, and they preferred it to the other materials. Lay Description What is currently known about Augmented Reality and learning? Augmented reality (AR) provides a new perspective for learning by allowing learners to visualize complex spatial relationships and abstract concepts., What the paper adds to the subject matter? AR improves learning performances to a similar extent as the most used teaching materials (both picture books and physical interactions) do., AR not only facilitates learning but also increases learning motivations better than conventional teaching materials do. The implications of study findings for practitioners. If children feel bored about reading textbooks, give them AR (because AR effectively enhances learning and children are more motivated when using AR)., AR teaching material is a good alternative to conventional picture book and physical interactions.

Mobile computers are now increasingly applied to facilitate face-to-face collaborative learning. However, the factors affecting face-to-face peer interactions are complex as they involve rich communication media. In particular, non-verbal interactions are necessary to convey critical communication messages in face-to-face communication. Through gathering discourse and non-verbal interaction records, this study explores the peer interactions supported by two collaborative applications: one with mobile computers and the other with shared-display groupware ( SDG). The results show that the students tended to interact with each other according to a distributed and an unsocial interaction pattern when using the application with mobile computers. In contrast, the students who learned with the SDG demonstrated a shared interaction pattern, whereby they often jointly focused on and referred to the shared work. The analysis of the students' work further found that a higher level of discussion was generally associated with the shared interaction pattern. The results seem to support SDG as being useful in augmenting face-to-face peer interaction supported by mobile computers. The implications derived from the findings also support the argument that non-verbal interaction records are useful for quantitatively and qualitatively analysing face-to-face peer interactions.

This study presents a look-ahead release planning approach on the basis of AutoMod simulation model for a sixth-generation thin film transistor liquid crystal display color filter (CF) fab in north Taiwan. The studied CF fab has two identical lines with the processes of black matrix (BM), color layer [red, green, and blue (RGB)], indium tin oxide, and photo spacer (PS). These two lines share two supporting processes, multi-domain vertical alignment (MVA) and laboratory (LAB). MVA has the capability and flexibility to provide the functions of RGB and PS, whereas LAB can provide the functions of BM and RGB. The production release planning becomes cornplex because of the equipment flexibility in supporting each other. An AutoMod simulation mode[ is therefore developed and validated using real data from the fab. The AutoMod simulation model is well representative of the real system with less than 10% difference in throughput in all production stations. Using simulation to look ahead, a production controller can predict potential equipment idleness and make adjustment to better utilize equipment capacity. On the basis of simulation with design of experiments, the proposed simulation-based look-ahead release plan is demonstrated to be effective in improving system throughput. [ABSTRACT FROM AUTHOR]
