Application of social presence principles to CSCL design for quality interactions
Year: 2012

Social presence is a key approach to activating interactions in Computer Supported Collaborative Learning (CSCL) but its approaches, definitions, and evaluations have not been coherently presented in previous research. This chapter provides practical suggestions and implications regarding CSCL, to help motivate social interactions among students and ensure effective and attractive learning. Three major approaches and focuses are discussed first: features of communication media (e.g. Short, et al. 1976) interaction and the learner's perception of interaction (e.g. Gunawardena Zittle, 1997; Tu McIssac, 2002) and learner's ability (e.g. Garrison et al. 2000; Garrison and Anderson, 2003) Integration and refinement of the central concepts are then illustrated. Conditions to establish social presence are introduced, using three steps for both individuals and groups: expression, perception, and recognition, which are all applicable to CSCL design. Media features are also explored as determinant factors when promoting social presence in a learning community.  A trust relationship among members is generally an important factor contributing to smooth communication in a community or group. This is true for communities within the field of Information and Communication Technology (ICT) As ICT advances and the pedagogical paradigm shifts from teacher oriented to learner oriented, interest has grown in using computer networks and social media for collaborative learning. This approach is called Computer Supported Collaborative Learning (CSCL) CSCL is defined as a collaborative learning environment based on a social constructivist approach (Vygotsky, 1978) in which learning is regarded as cognitive change promoted by interaction and activities among group members (King, 2007) Goldman, Digiano, and Chorost (2009) point out the potential of ICT applications to create powerful learning environments that support distributed, interactive, collaborative and constructive learning and learning assessment. Learners benefit from collaborative learning using social media, because electronic collaboration tools provide them with opportunities to solicit and share knowledge while developing common ground or intersubjectivity with their peers and teachers (Hara, Bonk, Angeli, 2000) Successful CSCL requires quality interactions; quality interactions need social interaction to establish a group culture, and an exchange of experiences as a foundation for knowledge production (Reneland Forsman Ahlback, 2007) One of common concerns in CSCL is how to support learners' social interactions, i.e. how to best activate collaborations in a learning community. Social presence, an approach intended to resolve this concern, focuses on quality interactions using CSCL structures as a framework. Social presence is a concept related to one's perceptions of oneself and others, and to social interactions in a community which could promote a trust relationship and play an important role in promoting CSCL. Social presence was originally defined as the "degree of salience of the other person in the interaction and the consequent salience of the interpersonal relationship" (Short et al. 1976) Social presence seems to increase the learners' satisfaction with learning (Gunawardena Zittle, 1997) and with social interactions, which are the foundation of social learning (Tu, 2000) Garrison and Anderson (2003) redefined social presence as "the ability of participants in a community of inquiry to project themselves socially and emotionally, as 'real' people, through the medium of communication being used" and introduced the indicators of social presence such as "self disclosure" and "quoting from other's messages." Social presence is also related to cognitive skills. When social presence is established, cognitive presence, a condition of higher order thinking and learning, is enhanced and sustained (Garrison Anderson, 2003) However, there is no consistent agreement on concepts and approaches to social presence among researchers. This is due to the broad diversity of social media, including social software such as Facebook, and Twitter, and to the many mobile devices now available. Further, new research methodology and data analysis methods related to social networks have been introduced, and possible ICT applications to educational settings have been widely expanded in response to research findings and the implications of computer mediated communication (CMC) associated with CSCL. This chapter introduces social presence theory as a framework for the design and application of social software for learning, and organizes conditions to promote social presence in the use of social software in educational settings. The intent is to identify major issues of existing social presence theories and to refine concepts of social presence in ICT learning environments, taking currently available social media tools into consideration. We wish to discuss essential conditions and approaches which foster the establishment of social presence for collaborative learning. This work is intended to help instructional designers and developers refer to the conditions and technologies that promote social presence for quality interactions in CSCL.  The importance of interaction and collaboration are strongly emphasized for effective and meaningful learning, as a result the current pedagogical paradigm shift to constructivism, social constructivism, and situated learning. Research and practice on CMC for CSCL have increased sharply. CSCL is an interactive learning environment based on the principles of social constructive learning. One of the key issues is how to best ensure active and continuous interaction in CMC (Barnes, 2008) In particular, interpersonal communication should be promoted to ensure an active virtual learning community in social media. Collaborative learning with high interaction between learners in both computer based and face to face situation can promote high performance in the realm of socioemotions such as satisfaction (Benbunan Fich et al. 2005) To provide readers with a solid background, we will briefly discuss the importance of interactions in CSCL, and of current issues related to social presence. Importance of Interactions in CSCL Collaborative learning is encouraged within the perspectives of constructivism, social constructivism, and situated learning. From the constructivist viewpoint, it provides opportunities for learners to claim ownership of their learning, learn meaningfully in authentic settings, and offers a recursive, interactive, multi perspective practice (Nett, 2008) Social constructivists emphasize the socio cultural dimension of learning (Bruner, 1960) social interactions (Bandura, 1977) and scaffolding with the zone of proximal development (Vygotsky, 1978) Kim (2001) focuses on the importance of culture and context in understanding phenomenon in community for collaborative learning. Based on theories of situated learning, the diversity of members is seen as a factor for success within a community of practice (Wenger, 1998) Learners learn through immersion in meaningful practices based on their backgrounds and experiences within a community (Cazden et al. 1996) These theoretical backgrounds indicate that "interactions among various types of members are important learning experiences for individuals and the community at large" (Buraphadeja Dawson, 2008) Learning environments and assignments for collaborative learning should be designed to ensure meaningful learning, authentic settings and contexts, and the interaction of diverse individuals. Collaborative learning differs from cooperative learning; it is also distinct from interactive learning with an underlying premise of consensus building through member cooperation (Theodore, 1999) This suggests that interaction should be a prerequisite for collaborative learning (Reneland Forsman Ahlback, 2007) One of differences between face to face collaborative learning and CSCL is that in CSCL communication and interactions are mediated via technology. Lehman and Conceicao (2010) point to the importance of a sense of presence in internet based social settings. A sense of presence in online learning can enhance the relationships among community members (Munro, 1998) For smooth and meaningful interactions, creating of a sense of presence in online settings (as we do in face to face settings) should be a first step toward significant communication. Social presence has proven to be a useful concept when analyzing the conditions needed for virtual learning communities in CSCL. Promoting social presence can create cohesive and interactive learning communities, and can also promote cognitive learning behaviors (Garrison and Anderson, 2003) Goertzen and Kristjansson (2007) conducted qualitative research on the relationship between social presence and interactive learning in TESOL classes. They suggested that social presence deepened the collaborative learning process as a result of the associated promotion of utterance, which activates interpersonal communication and cognitive engagement. Social presence helps educational practitioners and system developers design interactive learning environments. In this section, we focus on applying concepts of social presence to CSCL design to promote quality interaction. As advanced technologies have become available, diverse ways of collaborative activities can be provided. This affects the design of social presence in CSCL development. For CSCL design, pedagogical implications should be implemented which consider media selection and evaluation focusing on both the learning process and the learning outcome. CSCL often uses CMCs which involve synchronous and asynchronous communications and variety of media. Media broadly include individual components of software (e.g. text, pictures, animation, audio, video, and real objects) softwa
