This study aimed to clarify the relationship between media, learners' perception of social presence, and output in communicative learning using synchronous computer-mediated communication (SCMC). In this study, we developed four types of SCMC: videoconferencing (image and voice), audioconferencing (voice but no image), text chat with image (image but no voice), and plain text chat (no image and no voice). Each system allows learners to be conscious of and utter a target formulaic expression. I investigated the effect of each system on psychological perception and productive output as well as the relationship between perception and output. The results show that image and voice promote consciousness of natural communication and relief, while a text-mediated system enhances confidence in grammatical accuracy. In order to clarify the relationship between media, affective side, and output, path analysis was conducted using SPSS Amos 7.0. The results indicated that voice communication strongly affects both learners' affective side and output. The existence of a partner's image enhances the consciousness of natural communication, which leads to a number of self-corrections, an aspect of learning performance. However, voice communication has a negative effect on confidence in grammatical accuracy. (Contains 4 tables and 5 figures.)

Background: Augmented reality has been widely applied in various fields, and its benefits in language learning have been increasingly recognized. However, the investigation of effective learning behaviours and processes in augmented reality learning environments, taking into account temporality and analysis of differences in learning behaviours between learning achievements from the perspective of learning strategies, is still a topic that requires further research. Objectives: The goal of this research is to explore effective learning processes in AR language learning environments and learning behavioural patterns of learners with different performance levels via LA taking into account temporality. Methods: We used the learning application designed and developed in previous studies to understand the learning process and behavioural patterns of acquiring Japanese compound verbs with augmented reality. Lag sequential analyses were conducted to analyse the learning behavioural transitions using learning data. Additionally, frequent sequences were analysed using frequent sequence mining to compare the learning behavioural patterns of learners with different learning performances. Results and Conclusions: We investigated the learning process and behavioural patterns and discussed the language learning strategies employed in the augmented reality learning environment. The results indicated that learners primarily performed strategies of performed expressions, recombining, and structured reviewing in AR compound verb learning activities. Furthermore, the results revealed the different types of strategies applied by different learning performance learners, whereby the low group learners used the least variety of strategies, and the middle and high group learners employed repeating and deductive reasoning strategies that were not followed by the low group. Lay Description: What is already known about this topic: The development of information and communication technologies have made augmented reality (AR) technology gradually known and applied.The use of AR is increasingly gaining attention in language learning owing to advantages of increasing motivation and satisfaction, learning performance of language skills and improving interaction among materials, learners and teachers.Learning Analytics (LA) plays a key role in analysing learning data.LA studies in language learning are almost always used to monitor data such as attendance and amount of learned vocabulary. What this paper adds: Employing temporal LA techniques of lag sequential analysis and frequent sequence mining to investigate learners' behavioural patterns and processes.Learning behavioural patterns in AR learning environments were discussed from the perspective of language learning strategies.The three main learning behavioural patterns of analysing expressions, recombining, and structured reviewing in the learning process were confirmed.High performance level learners used the greatest variety of learning strategies. Implications: A new category of language learning strategies under technology‐enhanced language learning is required.Different learning strategies should be instructed for the learner's performance in the AR learning environment.Based on a full understanding of the role of AR system features, it is crucial to conduct instructional designs for language learning using language learning strategies.

This study examines potential designs in the usage of synchronous computer-mediated communication (SCMC) for communicative language learning in learner-centered communication. In this study, we compared four types of SCMC: text-based chat with and without interlocutors' image, video conferencing, and audio conferencing, each supporting of the use of formulaic expressions concerning communication strategies. We investigated the effect of each type of SCMC on four features of language learning: perceived consciousness of social presence; perceived consciousness of language learning in communication; productive performance; and consciousness of learning objectives. The results showed that the interlocutor's image has a main effect for social presence as well as on some aspects of productive performance, and that the use of voice has a significant effect on perceived consciousness of language learning in communication, productive performance and consciousness of learning objectives. In addition, an interaction effect was confirmed on perceived consciousness of social presence and productive performance. It can be said that social presence aids second language communication in learner-centered communication; however, it can inhibit consciousness of learning context and learning objectives.

Abstract This paper reports research results of the proposed experiential learning using a game-based educational material. The educational material was an application running on a mobile device and was supported for learners to study university library instruction. During the experiential learning, the learners answered several quizzes provided from the educational material. The quizzes were including experiential contents such as actually to find an academic journal or to reserve a learning room. In order to evaluate learning effectiveness of the experiential learning, this research made a comparative experiment. The experimental group used the educational material and the control group used another educational material of e-learning (non-experiential) but the contents was almost same as the contents of the experiential learning. The comparative experiment took several evaluation elements such as pre-/post-test scores, delayed-test scores and learning motivation scores based on IMMS of ARCS model. The experimental results revealed that experiential learning was superior for the several elements of these metrics. This research, furthermore, analyzed learner's operation data to the educational material and learner's behavior data during the learning in the experimental group. The analyzing results showed three types of the learning behaviors and indicated that an instructor needs to adopt suitable instructional design to each type to bring superior learning effectiveness.
