Real-time composer-performer collaboration as explored in Wilderness, a dance and audio installation
Description
From fall 2010 to spring 2011, the author was the pianist in twenty public performances of Wilderness, a site-adaptable dance and audio installation by choreographer Yanira Castro and composer Stephan Moore. Wilderness's music was generated as the result of an algorithmic treatment of data collected from the movements of both dancers and audience members within the performance space. The immediacy of using movement to instantaneously generate sounds resulted in the need for a real-time notational environment inhabited by a sight-reading musician. Wilderness provided the author the opportunity to extensively explore an extreme sight-reading environment, as well as the experience of playing guided improvisations over existing materials while incorporating lateral thinking strategies, resulting from a real-time collaboration between composer and performer during the course of a live performance. This paper describes Wilderness in detail with particular attention focused on aspects of the work that most directly affect the pianist: the work's real-time notational system, live interaction between composer and performer, and the freedoms and limitations of guided improvisation. There is a significant amount of multi-media documentation of Wilderness available online, and the reader is directed toward this online content in the paper's appendix.

Virtual Reality (hereafter VR) and Mixed Reality (hereafter MR) have opened a new line of applications and possibilities. Amidst a vast network of potential applications, little research has been done to provide real time collaboration capability between users of VR and MR. The idea of this thesis study is to develop and test a real time collaboration system between VR and MR. The system works similar to a Google document where two or more users can see what others are doing i.e. writing, modifying, viewing, etc. Similarly, the system developed during this study will enable users in VR and MR to collaborate in real time.
The study of developing a real-time cross-platform collaboration system between VR and MR takes into consideration a scenario in which multiple device users are connected to a multiplayer network where they are guided to perform various tasks concurrently.
Usability testing was conducted to evaluate participant perceptions of the system. Users were required to assemble a chair in alternating turns; thereafter users were required to fill a survey and give an audio interview. Results collected from the participants showed positive feedback towards using VR and MR for collaboration. However, there are several limitations with the current generation of devices that hinder mass adoption. Devices with better performance factors will lead to wider adoption.

Description
From Marathon to Athens was inspired by the legend of Pheidippides, a Greek messenger who ran approximately twenty-six miles between the cities of Marathon and Athens in ancient Greece to deliver an important wartime message. According to the legend, he died shortly after completing the journey. The marathon races of today were inspired by his story, though it may be more myth than reality. There is a great deal of inherent drama in the undertaking of such a feat, whether it be a marathon or any other test of strength and endurance. There is the rush of adrenaline when it begins, followed by the excitement and exhilaration of the first few miles. Then, there is a period of settling in and finding a groove - when the runner realizes that there is a long way to go, but is determined to pace him or herself and stay strong. All too often, there is the "wall" that appears about three-quarters of the way through, when it seems that there is no strength left to finish the race. Finally, there is the final push to the finish line - where the runner decides that they are going to make it, in spite of fatigue, pain, or any other obstacle. In this piece, I used a simple melody that was very loosely modeled after a melody from ancient Greece (the tune inscribed on the Epitaph of Seikilos). I used both Phrygian and Dorian modes, which, according to Plato, were most appropriate for soldiers. Throughout the piece, I used different instruments, mostly percussion, to represent the heartbeat of the runner. In the legend, the runner dies - in the piece, the heartbeat becomes very fast and then rather erratic. It then slows and, finally, stops. Though I find the story of Pheidippides inspiring, I wish all marathon runners and athletes of every kind (myself included) a safer and happier outcome!

Description
Second Language Learners face a unique set of challenges when it comes to the learning process. This dissertation study specifically focuses on those challenges and how to train teachers working within a co-teaching model in an international school in Bangkok, Thailand. Using the ideology proposed by Stephen Krashen as a part of his Input Hypothesis Theory and framing the results through the lens of Albert Bandura’s Self-Efficacy Theory, I studied the effects of a professional development model that focused on phonemic awareness, comprehensible input, and a collaborative teaching approach. Using this as my methodological framework, I found that teachers were able to improve their teaching skills and become more confident in their approach when provided with training that gave them specific responsibilities to address within the process of teaching. Through the use of pre-post surveys, interviews, and observations, I was able to examine how resource sharing and collaborative lesson planning allowed teachers to be more confident in their approach to teaching and their abilities to support students that were attending an international school that was a part of one of the most successful and academically rigorous networks of schools in the United States of America. It was through an intentional designation of tasks and a collaborative training approach that teachers were not only able to better understand the needs of their students but also find ways to work with and learn from one another in the training process. Ultimately, I discovered that allowing teachers to share resources and best practices allowed them to build quality and far more engaging lessons for their students.

Collaborative Video Viewing (CVV) transforms passive video-based learning into an engaging, active process. While collaborative modes have different affordances that could potentially influence knowledge co-construction, no study has directly assessed the impact of collaborative modes in CVV activities. Therefore, this current study seeks to investigate how collaborative modes influence learning outcomes, learning engagement, group interaction and the co-construction process.The study utilized a within-subject, counterbalanced experimental design, in which each participating undergraduate student was paired in dyads. These dyads were assigned to engage in two separate CVV sessions: one using synchronous voice-based collaborative mode (SV) and the other using asynchronous text-based collaborative mode (AT). After each session, participants completed a test consisting of retention and application questions. ANCOVA was utilized to analyze the test scores.
To ascertain if the different scores were a result of varying levels of learning engagement, dyad discussions were coded using ICAP coding (Chi & Wylie, 2014). Furthermore, to delve deeper into the group interaction mechanism in SV and AT, a codebook was developed to analyze the discourse that occurred during dyad interaction. Sequential analysis and thematic narrative analysis were employed to visualize interaction patterns and the co-construction process.
The findings indicated that, generally, SV dyads performed better on application scores and have significantly higher interactive learning engagement than AT dyads. In line with ICAP predictions, the higher-score groups in both SV and AT engaged in more generative processes, leading to more constructive and interactive comments than lower-scoring groups. In terms of group interaction, both SV and AT primarily use descriptive discourse for co-explanation. However, the SV groups exclusively introduce discourse expressing uncertainty, which subsequently leads to group negotiation. The study identified distinct knowledge co-construction phases, including (a) co-explanation, (b) negotiation, and (c) application. Although the co-explanation phase is the most frequent in all dyad scores in both SV and AT, the negotiation phase appears to differentiate low-high score dyads from high-high score dyads.
These findings hold research implications for understanding learning engagement and group interaction in various online collaborative modes, as well as for the instructional design of active video-based learning through collaborative video viewing.
