Synchronous communication technology
W. Jonathan Barnes, Memorial University of Newfoundland
Definitions and background
Synchronous communication (SC) is direct communication that occurs in real-time (Mabrito, 2010; Wang, 2008). It is incorporated into distance education through technologies such as instant messaging, chat rooms, and audio and video conferencing (Chui, Yang, Liang & Chen, 2010). Although audio and video conferencing are growing in popularity, text-based chat services still remain the most popular form of synchronous communication technology (SCT) (Chui et al., 2010). Software such as Adobe Connect, Elluminate LiveTM and Horizon WimbaTM (now known as Blackboard CollaborateTM) are real-time communication software used to access the technology needed for SC (Martin, Parker, & Eyarzun, 2013). They also include other tools such as shared applications and whiteboards, emoticons, hand raising, and a class voting function (Murphy, Rodriguez-Manzanares & Barbour, 2008; Chui et al., 2010). Freeware versions of similar software include DimDimTM and WiziqTM (Martin, Parker, & Oyarzun, 2013).
Recent and rapid improvements in technology have made the use of SC in distance education viable (Ng, 2007) and more widely used (Hrastinski, 2006). In the Canadian province of Newfoundland and Labrador, as much as 60% of distance instruction occurs synchronously (Murphy & Rodriguez-Manzanares, 2008b). This type of synchronous distance instruction is often referred to as a virtual classroom (Murphy & Coffin, 2003).
Affordances
SCT allows users to communicate online in real-time (Steel & Jones, 2013). This affordance provides immediacy to communication and strengthens collaboration in distance education (Groen, Tworek, & Soos-Gonczol, 2008). "Teachers and students may be located in rooms that are thousands of miles apart and yet still spontaneously communicate together as if they were physically co-present" (Murphy, Rodriguez-Manzanares & Barbour, 2011, p. 584), making it possible to collaborate with their peers without having to travel to campus (Martin et al., 2013). Using SC software students can collaborate in activities by participating in breakout rooms where they can converse privately with teacher supervision (Martin, Parker, & Deale, 2012). Murphy and Ciszewska-Carr (2007) identified that students communicating in break out rooms is an effective means of engaging students and encouraging group communication and collaboration.
SCT allows teachers to determine students' understanding of content and provide immediate feedback to students through a range of communicative tools in the virtual classroom (Martin et al., 2013). SC enables teachers to "ask students questions, test their understanding, test their ability, or get their opinion" (Murphy & Rodriguez Manzanares, 2008a, p. 52). SC can also provide individual feedback and guidance to students outside of regular class time by allowing teachers to be available to students via chat (Murphy & Rodriguez Manzanares, 2008a). University students reported benefiting from the immediate feedback provided through synchronous online classes (Martin et al., 2012) and the virtual office hours that teachers held (Steel & Jones, 2013).
SCT enables students in the virtual classroom to have a social presence similar to a traditional classroom (Stewart, Harlow, & DeBacco, 2011). SCT empowers students to socially interact and generate conversation in a real-time online environment (McBrien, Jones, & Cheng, 2009) that provides teachers and students the opportunity to get to know each other personally (Murphy & Rodriguez-Manzanares, 2008a). Chat features of SCT allow multiple students to contribute to group a discussion, which results in increased class participation and social presence (Bower, 2011; Murphy & Rodriguez-Manzanares, 2008a). Direct messaging creates a natural environment for students to conveniently and spontaneously express a range of emotions and socially interact (Murphy & Nippard, 2011), which results in activating the quieter students because they feel more confident socializing and expressing their own opinions (McBrien et al., 2009). Quiet students that never speak up in a traditional class may consistently interact in the virtual classroom (Murphy & Rodriguez-Manzanares, 2008a).
