Context Counts: Effects of Work versus Non-Work Context on Participants’ Perceptions of Fit in E-mail versus Face-to-Face Communication

There is a general need to understand better how context can affect evaluation, usage, and productivity of IT in research and practical settings. This paper investigates how perceived effectiveness of e-mail-style computer-mediated communication (CMC) differs between work and non-work contexts of use, and contrasts these differences with perceived effectiveness of face-to-face communication (FtFC). From the prior literature, we identified seven major activity domains that are prominent in CMC research. We developed a set of activity scales and corresponding measures of normative cognitive effort (NCE) for these domains and conducted an initial study to evaluate the overall instrument. In a second study, we measured perceived effectiveness of the communication mode within each activity domain among subjects who had communicated via e-mail and FtFC over a 15-week period. Some subjects communicated to support team-based software development (work context), and others communicated for personal interest (non-work context). We find communication technologies, activities, and contexts of use jointly determine perceived effectiveness; context influences perceived effectiveness primarily through interactions; and NCE successfully predicts perceived effectiveness based upon normative differences among activities. Our findings extend prior research in the area of task-technology fit to incorporate context effects, suggest that context is an important consideration in designing research, and introduce NCE as a method for predicting fit that can be applied even prior to system design. We conclude that the differential effects of work vs. non-work contexts are too large to be ignored, and we recommend an increased focus on context effects in CMC research and practice

Factors influencing the success of computer mediated communication (CMC) environments in university teaching: a review and case study

Despite its potential benefits, the effectiveness of CMC when used to support learning in higher education is very variable, making it important to identify those factors which best predict successful implementations. A review of the literature from the past few years, presented in the first half of this paper, suggests that, consistent with Activity Theory (Leont'ev, 1978), the critical factors are those which provide a context and rationale for online communication by helping users to establish a shared purpose. However, generating empirical support for this hypothesis presents two kinds of methodological problem: specifying the methods and measures necessary to discern the existence and impact of shared purpose; and dealing with the difficulties of making controlled comparisons in this area. The second half of the paper illustrates, via an implementation case study, something of how these methodological problems might be resolved, and presents evidence in favour of the central importance of shared purpose

The efects of peer corrective feedback trainning in face to face interaction and synchronousvideo-based computer-mediated comunication

Tesis (Profesor de Inglés para la Enseñanza Básica y Media y al grado académico de Licenciado en Educación)This quasi-experimental study was conducted in a private school, in Santiago, Chile, with four groups formed by 9th graders with the same L1 (Spanish) immersed in an EFL context. The purpose of the study was to examine ways in which the potential of peer interaction on learning is maximized. Specifically, the study examined two instructional techniques, both of which have been gaining increasing attention from second language acquisition researchers: (a) training learners how to correct each other (corrective feedback: CF), and (b) synchronous communicative interaction via video-based computer-mediated communication (SVCMC). Participants were divided into four groups depending on their experimental conditions. Group A (SVCMC+CF training) engaged in communicative peer interaction via SVCMC and received CF training. Group B (SVCMC-CF training) was given the same peer interaction tasks but did not receive any CF training. Groups C (FTF+CF training) and D (FTF-CF training) engaged in the same tasks in face-to-face in the classroom while only Group C received CF training. The intervention period lasted two weeks, consisting of four classes of 45 minutes for each of the four groups. The analysis involved (a) learners’ interactional behaviors, namely, language-related episodes, (b) their developmental outcomes with pre- and posttests focusing on past tense and locative usages, and (c) their perceptions based on exit questionnaire with close- and open-items. The results of this study reflected 3 main findings in peer interaction, corrective feedback, and SVCMC. With regard to interactional patterns (peer interaction), corrective feedback training promotes collaboration and so FTF environments, yet in SVCMC dominant patterns were more likely to arise. Meanwhile, CF training helped enhance learners’ language development as their results in the post-test were higher than in the pre-test and, in turn, SVCMC groups outperformed FTF groups. Concerning students’ perceptions, they overtly expressed positive beliefs regarding Peer Corrective Feedback and SVCMC activities. In short, clear differences were found among groups with different interventions resulting in distinct patterns, L2 development outcomes, and learner perceptions.Este estudio cuasi-experimental fue conducido en un colegio privado en Santiago de Chile, con cuatro grupos formados por estudiantes de primer año medio, cuya lengua nativa es el español. Los estudiantes estuvieron inmersos en un contexto EFL. El propósito del estudio fue examinar medios por las cuales el potencial de la interacción entre pares en el aprendizaje sea maximizado. Específicamente, este estudio examinó dos técnicas instructivas, las cuales han recibido recientemente atención paulatina de los investigadores en el campo de la adquisición de un segundo idioma: (a) capacitar a los estudiantes en como corregir a sus pares (retroalimentación), e (b) interacción comunicativa sincronizada a través de video conferencias (ICSV) mediadas por computadores. Los participantes fueron divididos en cuatro grupos según sus condiciones experimentales. El Grupo A (ICSV+ capacitación en retroalimentación) involucrado en interacción comunicativa— entre pares— a través de ICSV y recibieron instrucción en retroalimentación entre pares. Al Grupo B (ICSV – capacitación en retroalimentación) se le dio las mismas tareas, pero no recibió capacitación en retroalimentación. El Grupo C (cara a cara + capacitación en retroalimentación) y el Grupo D (cara a cara – capacitación en retroalimentación) participaron en las mismas tareas cara a cara en la sala de clases mientras que solo el Grupo C recibió capacitación en retroalimentación. El periodo de intervención fue de 2 semanas, compuesto de 4 clases de 45 min para cada uno de los grupos. Este análisis involucró (a) comportamientos interaccionales de los estudiantes, es decir, episodios relacionados con el lenguaje, (b) los resultados que reflejaron el desarrollo del lenguaje de los estudiantes fueron obtenidos mediante una evaluación previa a la intervención y otra posterior a la intervención; las evaluaciones se enfocaron en el uso del pasado simple y locativos, finalmente (c) las percepciones de los estudiantes obtenidas mediante un cuestionario de preguntas cerradas y abiertas. Los resultados de este estudio reflejaron 3 hallazgos principales en cuanto a interacción entre pares, retroalimentación, e ICSV. En cuanto a los patrones interacciónales (interacción entre pares), la retroalimentación y la comunicación cara a cara resultaron promover la colaboración, a diferencia de ICSV en la cual los patrones dominantes tuvieron más probabilidades de surgir. Mientras tanto, la capacitación en retroalimentación ayudó al mejoramiento del desarrollo del lenguaje de los estudiantes ya que sus resultados a lo largo de las evaluaciones pre y post presentaron un alza y, en consecuencia, los grupos que interactuaron a través de ICSV superaron a los grupos que interactuaron cara a cara. Tomando en cuenta las percepciones de los estudiantes, ellos expresaron abiertamente ideas positivas en cuanto a las actividades la capacitación en retroalimentación e ICSV. En resumen, diferencias claras fueron encontradas entre los grupos con diferentes intervenciones resultando en distintos patrones de interacción, resultados en el desarrollo del lenguaje, y percepciones de los estudiantes

Virtual reality in theatre education and design practice - new developments and applications

The global use of Information and Communication Technologies (ICTs) has already established new approaches to theatre education and research, shifting traditional methods of knowledge delivery towards a more visually enhanced experience, which is especially important for teaching scenography. In this paper, I examine the role of multimedia within the field of theatre studies, with particular focus on the theory and practice of theatre design and education. I discuss various IT applications that have transformed the way we experience, learn and co-create our cultural heritage. I explore a suite of rapidly developing communication and computer-visualization techniques that enable reciprocal exchange between students, theatre performances and artefacts. Eventually, I analyse novel technology-mediated teaching techniques that attempt to provide a new media platform for visually enhanced information transfer. My findings indicate that the recent developments in the personalization of knowledge delivery, and also in student-centred study and e-learning, necessitate the transformation of the learners from passive consumers of digital products to active and creative participants in the learning experience

A review of the empirical studies of computer supported human-to-human communication

This paper presents a review of the empirical studies of human-to-human communication which have been carried out over the last three decades. Although this review is primarily concerned with the empirical studies of computer supported human-to-human communication, a number of studies dealing with group work in non-computer-based collaborative environments, which form the basis of many of the empirical studies of the recent years in the area of CSCW, are also discussed. The concept of person and task spaces is introduced and then subsequently used to categorise the large volume of studies reported in this review. This paper also gives a comparative analysis of the findings of these studies, and draws a number of general conclusions to guide the design and evaluation of future CSCW systems

A Cost-Benefit Analysis of Face-to-Face and Virtual Communication: Overcoming the Challenges

Virtual communication has become the norm for many organizations (Baltes, Dickson, Sherman, Bauer, & LaGanke, 2002; Bergiel, Bergiel, & Balsmeier, 2008; Hertel, Geister, & Konradt, 2005). As technology has evolved, time and distance barriers have dissolved, allowing for access to experts worldwide. The reality of business today demands the use of virtual communication for at least some work, and many professionals will sit on a virtual team at some point (Dewar, 2006). Although virtual communication offers many advantages, it is not without challenges. This article examines the costs and benefits associated with virtual and face-to-face communication, and identifies strategies to overcome virtual communication\u27s challenges

Together we stand, Together we fall, Together we win: Dynamic Team Formation in Massive Open Online Courses

Massive Open Online Courses (MOOCs) offer a new scalable paradigm for e-learning by providing students with global exposure and opportunities for connecting and interacting with millions of people all around the world. Very often, students work as teams to effectively accomplish course related tasks. However, due to lack of face to face interaction, it becomes difficult for MOOC students to collaborate. Additionally, the instructor also faces challenges in manually organizing students into teams because students flock to these MOOCs in huge numbers. Thus, the proposed research is aimed at developing a robust methodology for dynamic team formation in MOOCs, the theoretical framework for which is grounded at the confluence of organizational team theory, social network analysis and machine learning. A prerequisite for such an undertaking is that we understand the fact that, each and every informal tie established among students offers the opportunities to influence and be influenced. Therefore, we aim to extract value from the inherent connectedness of students in the MOOC. These connections carry with them radical implications for the way students understand each other in the networked learning community. Our approach will enable course instructors to automatically group students in teams that have fairly balanced social connections with their peers, well defined in terms of appropriately selected qualitative and quantitative network metrics.Comment: In Proceedings of 5th IEEE International Conference on Application of Digital Information & Web Technologies (ICADIWT), India, February 2014 (6 pages, 3 figures

Exploring personality-targeted UI design in online social participation systems

We present a theoretical foundation and empirical findings demonstrating the effectiveness of personality-targeted design. Much like a medical treatment applied to a person based on his specific genetic profile, we argue that theory-driven, personality-targeted UI design can be more effective than design applied to the entire population. The empirical exploration focused on two settings, two populations and two personality traits: Study 1 shows that users' extroversion level moderates the relationship between the UI cue of audience size and users' contribution. Study 2 demonstrates that the effectiveness of social anchors in encouraging online contributions depends on users' level of emotional stability. Taken together, the findings demonstrate the potential and robustness of the interactionist approach to UI design. The findings contribute to the HCI community, and in particular to designers of social systems, by providing guidelines to targeted design that can increase online participation.
