An overview of fundamentals, best practices and a tutorial.

Augmented Reality (AR) is a relatively new technology and is increasingly being posited as an educational game-changer, particularly - but not exclusively - in language learning. On a scale where the virtual and real world sit at opposite ends of the spectrum, AR sits in-between, combining real world elements with virtual overlays. Research suggests that an obstacle to English language learning in countries where English is not the first language (EFL) is a "...lack of authentic situations outside of the classroom for practising English communication skills" [1]. AR technology, by combining elements of real-life and virtual content could potentially overcome some of these limitations. However, as with all technologies, the use of AR in the classroom is not only confined to the learner, but also largely dependent on the willingness and skills of teachers to utilise it effectively. This study hopes to shed some light on the possible uses, benefits, and challenges that AR may present to the field of EFL learning in an Egyptian International Baccalaureate (IB) school.
In today’s technological world, human intertwinement with the rest of nature hasbeen severely diminished. In our digital culture, many people hardly have any direct experience of and sense of connection with “the real” of the natural world. The author assumes that when we want to find ways to mend this gap, arts-based environmental education (AEE) can play a meaningful role. In AEE, artmaking is regarded as itself a way of potentially gaining new understandings about our natural environment. As a reflective practitioner, the author facilitated three different AEE activities, at several times and at diverse locations. On basis of his observations, memories, written notes, audio-visual recordings and interviews with participants, teachers and informed outsiders, he interpreted the experiences both of participants and himself. To this end he employed interpretative phenomenological analysis paired with autoethnography.The artmaking activities researched here aimed to bring about a shift in focus. Participants were encouraged to approach natural phenomena not head-on, but in an indirect way. Moreover, the artmaking process aspired to heighten their awareness to the presence of their embodied self at a certain place. The research questions that the author poses in this study are: (1) What is distinctive in the process of the AEE activities that I facilitate?; (2) Which specific competencies can be identified for a facilitator of AEE activities?; and (3) Does participating in the AEE activities that I facilitate enhance the ability of participants to have a direct experience of feeling connected to the natural world?In this explorative study, the author identifies facilitated estrangement through participating in AEE as an important catalyst when aiming to evoke such instances of transformative learning. In undergoing such moments, participants grope their way in a new liminal space. Artmaking can create favorable conditions for this to happen through its defamiliarizing effect which takes participants away from merely acting according to habit (on “autopilot”). The open-ended structure of the artmaking activities contributed to the creation of a learning arena in which emergent properties could become manifest. Thus, participants could potentially experience a sense of wonder and begin to acquire new understandings – a form of knowing that the author calls “rudimentary cognition.” The research further suggests that a facilitator should be able to bear witness to and hold the space for whatever enfolds in this encounter with artistic process in AEE. He or she must walk the tightrope between control and non-interfering.The analysis of the impacts of the AEE activities that were facilitated leads the author to conclude that it is doubtful whether these in and of themselves caused participants to experience the natural environment in demonstrable new and deep ways. He asserts that most of their awareness was focused on the internal level of their own embodied presence; engagement with place, the location where the AEE activity was performed, seemed secondary. The findings show that AEE activities first and foremost help bring about the ignition and augmentation of the participants’ fascination and curiosity, centered in an increased awareness of their own body and its interactions with the natural world. The present study can be seen as a contribution to efforts of envisaging innovative forms of sustainable education that challenge the way we have distanced ourselves from the more-than-human world.

Based on the theory of embodied cognition we developed NOOT, at tangible tool that allows marking audio-moments during creative sessions. A detailed analysis of using NOOT in practice lead to a reconceptualization of NOOT within processes of external scaffolding. It also spurred a new design project focused on reflection during group sessions
Electromagnetic articulography (EMA) is one of the instrumental phonetic research methods used for recording and assessing articulatory movements. Usually, articulographic data are analysed together with standard audio recordings. This paper, however, demonstrates how coupling the articulograph with devices providing other types of information may be used in more advanced speech research. A novel measurement system is presented that consists of the AG 500 electromagnetic articulograph, a 16-channel microphone array with a dedicated audio recorder and a video module consisting of 3 high-speed cameras. It is argued that synchronization of all these devices allows for comparative analyses of results obtained with the three components. To complement the description of the system, the article presents innovative data analysis techniques developed by the authors as well as preliminary results of the system’s accuracy.
In this study, we compared the impact of audio-, video-, and text-chat interaction on target language use during online learner-learner interaction and on learner affect amongst adolescent learners of German as a foreign language. Repeated measures and ANOVA analyses revealed a high percentage of target language output in all conditions for all four tasks, especially in text- chat. Audio-chatters produced the most output and used the most meaning negotiation, compensation strategies, self-repair and other-repair strategies. Learners in all conditions gained in enjoyment, willingness to communicate and self-efficacy. Anxiety reduced for text-chatters. Task effects partly determined the quantity of L2 output, while condition effects determined meaning-oriented and form-focused processing.

Physical Education (PE) is beneficial for students’ mental and physical health, however, teenagers are increasingly becoming less motivated to actively participate in the current form of PE. Motivational studies show that collective physical activity augmented by playful interactions could encourage more participation and social engagement in physical activities (PA). In this paper, we present a within-subject field study with 20 teenagers formed into five groups sized equally. The study is conducted using Shuttlezap, a prototype that provides realtime playful audio augmentation to the process of the activity. Results show that the teenagers enjoyed playful audio augmentation and were socially engaged with an enhancement of their perception of competence. By further comparing the conditions between with and without the audio augmentation, we found that the playful audio augmentation positively contributed to the playfulness in terms of perceived relaxation and expression. We conclude with design implications for social play in the context of PE for teenagers.
