THE DIFFERENCE IN COMMUNITY BETWEEN SYNCHRONOUS, ASYNCHRONOUS, AND BLENDED ONLINE CLASS


CHAPTER II

A LITERATURE REVIEW

Introduction
            Our world is changing.  Every day there are more new products and ideas that give us cause to wonder.  One area that has changed at a remarkable speed is that of computer technology.  The growing number of ways to use the Internet has become a topic of discussion for professionals in many fields, including the field of education.  One area for which educators have been using the Internet is for distance courses.  Few teachers are trained in long-distance classes (e-learning) or how the change in format affects their students.  But before teachers can be trained, an agreement of what practices are best needs to be decided.                                                                                             
             The popularity of e-learning exists due to technology that makes learning available to those who have been unable to learn because of their location, socioeconomic circumstances, disability, and schedules (Holmes & Gardner, 2006).  The number of college distance students has risen markedly over the past decade.  According to the National Center for Education Statistics (2011) the percentage of undergraduate students who took any distance course rose from 16 percent in 2003-04 to 20 percent in 2007-08.  Meanwhile, elementary and secondary schools who see distance education as a way to combat the problems of overcrowding and students’ demands for Advanced Placement, college-level courses, and individualized schedules also rose from an estimated 317,070 students in 2002-03 to 506,950 students in 2004-05 (National Center for Education Statistics, 2008).                                                  
             As our world becomes more focused on the technological side of life, instructors need to be aware of the ways the online class differs from the traditional face-to-face class in order to reach students as effectively as they can.  One aspect that changes is the level of interaction.  This is described as occurring in three different areas: social interaction between the different students (social presence), social interaction between the students and their instructor (teacher presence), and cognitive interaction between the students and the information being learned (cognitive presence).                                       
           This portfolio will explore the ideas of presence with a focus on the relationship between social presence and perceived learning while showing the history of the field and some of the ideas contained within it.  Information for this literature review was gathered from searches of several databases including library online catalogs, ABI/INFORM (Business), Academic Search Premier, Emerald FullText, and ERIC (Education) using search terms which included community of inquiry, online instruction, teaching, online learning, and immediacy.                           
                                                              
Moving to the Online Environment

            When students are together physically, they can easily see each other as individuals and assess the social status of their classmates.  The classroom’s oral communication contains gestures, breaks, intonation, and body language which we are skilled in reading.  When working online, this is more difficult (Slagter van Tryon & Bishop, 2009).  Garrison, Anderson and Archer (2000) also voice concerns over the change from oral communication to text-based.  Not only does oral communication provide the above cues, but it provides a richer environment when it comes to the social and emotional aspects.  In the end, those who are skilled in oral communications may prefer the traditional classroom while those who prefer the written word may prefer the online class (Salmon, 2000).  But this is not the only change seen by researchers.
            Hudson and Bruckman (2004) found that moving conversations from the classroom to the online environment caused behavioral changes amongst participants.  One change observed was in self- awareness.  In the traditional classroom, students are aware of an audience making judgments of their actions.  This often increased their level of self-awareness.  In contrast, students did not feel the same judgment in the online class, thus reducing their feelings of self-awareness.  This is change would affect many students’ behavior due to their level of confidence.  It may be that students worry in traditional classes because they give their audience cues, such as pausing or stammering, when they make mistakes.  When using the online format, students can reflect about what they have written, and make desired changes, before allowing others to view it.  Another finding of Hudson and Bruckman’s was that students engaged in several small conversations instead of one large conversation.  They could continue the discussions that were interesting to them, instead of being forced to move on when the instructor felt the class was ready for something else.

Types of Classes

            Online learning management systems (LMSs) provide the instructor with a shell to place course content and offer different methods to deliver information.  Students may access materials, interact with their instructor and collaborate with each other in several ways, some synchronous, some asynchronous (Holmes & Gardner, 2006).  The LMS allows students to do the three things felt to be necessary for them to learn in the online environment: interact with the instructor, other learners, and the content (Dennen, Darabi, & Smith, 2007).                  
         The most basic kind of asynchronous lessons contain text-based chat sessions that any participants can contribute.  The asynchronous method of learning allows students to access their classes “anytime” via the Internet by using systems such as discussion threads, structured groups, bulletin boards and computerized conferencing.  In this method the sending and receiving of information and comments are separated in time.  In order for students to learn effectively, the technology must support the ability for students to engage in collaborative social/pedagogical processes (Hiltz & Turoff, 2002; Hiltz, Harasim, & Turoff, 2007).  Participants can see who else is online at the same time, they can address messages to one or more participants, and they can see messages appear on the screens of the addressee almost as soon as they are sent.  In this method, participants can reply very quickly or wait with their reply.  This time delay can allow participants to explore before formatting their reply (Salmon, 2000).  However, the lack of immediacy can be frustrating for participants.  Responses to postings may take hours or days.  This delayed response may worry the sender as to whether the message was received to not found worthy of a reply (Hiltz, Harasim, & Turoff, 2007).    
            During synchronous classes, students meet at the same time with their instructor. All communications are immediate and all participate in the same conversations and hear or see the same information.  This style of class allows participants to feel as though there is immediate contact with others (Salmon, 2000).

Problems Found

            The online environment consists of different social norms than what most students are used to.  The usual mechanisms for communication and assessing social concerns are not always available.  Instead, there is a lack of auditory and visual cues combined with asynchronicity and a dependence on the text-based format.  Nicol, Minty, and Sinclair (2003) explored the lack of facial cues in the online class and found that students felt less pressure to contribute during online discussions.  In addition, students felt they could be more selective in with whom to communicate or could even hide online.              
            Another stumbling block to learning is what Slagter van Tryon and Bishop call “channel noise” (Slagter van Tryon & Bishop, 2009, p. 307).  Channel noises are the items which interfere with a student’s ability to pay attention to their cognitive resources.  They describe social aspect as one type of channel noise while the reliance on text-based communication is another.  When dealing with text, it is much easier for students to misunderstand each other, which makes learning collaboratively more difficult.  Slagter van Tryon and Bishop feel that instructors must provide opportunities for students to interact often on a deeper level so that the group may establish its own norms of social interaction which can lead to learning.

Student Perceptions 

            In 2009, Hill, Song, and West asked how much interaction between students is needed, what kind of interactions they should be, and how these interactions may influence the learning process.  Their findings claim that some students felt the social interactions to be “forced and unnatural” (Hill, et al., 2009, p.91).  They concluded that the four significant areas that affect social learning as it pertains to knowledge are: “epistemological beliefs, individual learning styles, self-efficacy, and motivation” (Hill, et al., 2009, p. 95).  In a similar way, when Jianfei, Tregonning, and Keenan (2008) asked Canadian physicians about their participation in online social activities and learning discussions, just 35% felt more connected to others while 16% did not feel any closer.  Eighteen percent stated that they were not interested in participating at all.  Only 45% reported that participating in discussions more would help them learn more.  Powell, Tindal and Millwood (2008) found that there was a marked difference in the students’ preferences in participation; some became active in larger communities while others selected small groups with a deep level of trust between members.
            Data analysis from 73 courses offered in 1999 showed that three factors were significantly related to student perceptions: “clarity and consistency in course design, contact with and feedback from course instructors, and active and valued discussion” (Swan, 2002, p. 44).  Her study also showed that when comparing student satisfaction, perceived learning, perceived interaction with the instructor, and perceived interaction with peers, that the strongest relationship was between student satisfaction and perceived learning.  Students who rated their level of participation highly also reported a high level of both course satisfaction and perceived learning.  As may be expected, students who rated their course satisfaction and perceived learning the lowest also rated their own participation as low.  In addition, students who rated their own level on interaction with classmates as high had significantly higher levels of both course satisfaction and perceived learning.  So the question arises of how to convince students to interact and how much this interaction may affect their learning outcomes.  Many researchers have developed learning models in an attempt to address this part of the problem.   

Learning Models    

            In 2000, Salmon found that some students who normally contribute in the traditional classroom were not comfortable contributing in the inline environment while other students preferred the ability to change their messages before submitting them.  She designed a five-stage model that promotes learning with different amounts of interactivity.  In this model, participants begin to support each other’s goals in stage three and grow more collaborative during the final two stages.  During Salmon’s fourth stage, participants may interact in a more exposed and participative way.  The share their ideas about the topic, read and respond to others frequently and many engage in very active learning.  She observed that students widened their own concepts and theories through debating and sharing examples with others.  She also grouped students into one of three types.  The “swimmers” are willing to help others, dive in early, have online class experience, and often know other computer systems.  The “wavers” often need help or encouragement, depend on help lines, and come late but do become active once helped.  While the “drowners” find it tough to ask for help, are not motivated, complain that the work is irrelevant or too time-consuming, find it hard to build relationships, and do better with a swimmer as a mentor. 
         Salmon’s five-stage model is pictured here (Salmon, 2000) and a chart of all the learning models may be viewed on page 27.

The 5-Stage Model

            Maor (2003) designed a lesson whose purpose was to implement a community of learners who would engage in interactions and peer learning in order to produce reflective thinking.  He set up an Activity Room where discussions between students and the instructor could take place.  His results implied that participants must become reflective practitioners in order to ensure quality collaborative learning online.             
         The learning model Bird (2007) used was the 3 ‘C’ model.  It consisted of Content, Construction and Consolidation.  In this model, Content represents the declarative knowledge of the course, Construction refers to the students’ engagement that facilitates knowledge construction, and Consolidation includes the reflective process that enables learners to develop new understandings.  Here is an adapted version of the 3 “C” Model (Bird, 2007).

The 3 “C” Model

            Holmes and Gardner  (2006) developed an e-learning “flower” with the petals of search, select, explore, test, collaborate, analyze, create, discuss, apply, understand, synthesize, and promote in order to compensate for how today’s’ technology does not offer information in an ordered fashion online.  They felt that students need to be able to deconstruct the information and rebuild it as their own.  By sharing ideas with others who are working toward the same goal, ideas may be articulated, rested and the information consolidated into a new form of knowledge. Their Flower Petal Model is shown below (Holmes and Gardner, 2006).
        

Figure 3.
The Flower Petal Model

            The most famous and accepted model of online learning is that of the Community of Inquiry.  Garrison, Anderson & Archer (2000) defined the Inquiry of Communication model (CoI), which makes the assumption that students learn through the interaction of three core elements: cognitive presence, social presence, and teaching presence.  The Inquiry of Communication model is shown below (Garrison et al., 2000).


                            
        
Figure 4.
The Community of Inquiry Model

             In this model, Garrison et al. found that cognitive presence, which is thought to be a major part of the critical thinking process, was the most important of the three in higher education.  They define social presence as “the ability of participants in the Community of Inquiry to project their personal characteristics into the community, thereby presenting themselves to the other participants as ‘real people’ “ (Garrison, Anderson & Archer, 2000, p. 89).  In addition, social presence contains the elements of emotional expression, open communication and group cohesion which will build understanding.  They felt that social presence was important due to the indirect affect it has on the community of learners and the journey to their cognitive goal.  Teaching presence belongs to those who design the educational experience and facilitates the journey of the learners.  They concluded that all three presences must be included in a critical community of inquiry for educational purposes.  In today’s world, where the abundance of information requires students to sift through large quantities of information, it is especially important that students be part of a community in order to interact in an educationally productive manner.  When this is accomplished and combined with an appropriate teaching presence, they believe it can lead to a high level of cognitive presence which will lead to a higher level of thinking.  How does this help students learn?        
            The educational theory that applies here is that of constructivism.  Holmes and Gardner (2006) were able to put Garrison, Anderson & Archer’s (2000) idea of social learning into the context of constructivism with the following definition:
Socio-constructivism—the need for assistance from a more knowledgeable other is the conceptual point at which cognitive constructivist theory, in which the learners ‘construct’ their own knowledge, skills or understanding from their own observational and reasoning capabilities, evolves into the prevailing socio-constructivist theories of today.  In essence, the socio-constructivist model requires a third dimension to the interaction between the learners and their environment, that is, other people.  These others may be learners or tutors (Holmes & Gardner, 2006, pp 83-84).
So the members of a social community will work together to construct the knowledge they seek.      
            The Garrison, Anderson & Archer (2000) CoI model has become a standard in the field and some have tested its ideas.  Another definition of social presence is found in the research of Kehrwald (2008) who said, “Social presence is an individual’s ability to demonstrate his/her state of being in a virtual environment and so signal his/her availability for interpersonal transactions” (Kehrwald, 2008, p. 94).  It is with social presence that students are able to inhabit the online environment and indicate both their existence and their willingness to interact with others.  His research further indicated that participants view each other as real people; thus the acknowledgement that by participating online that it is another human you are interacting with and not a machine.  Once this is established, the two participants may interact and develop a sense of connectedness, complete with varying levels of trust, respect, rapport and empathy.  If they feel safe and comfortable they will be willing to put themselves at risk through participation in interpersonal exchanges.  This seems to agree with and build on the Garrison et al. model.                                                                                               
         According to Garrison and Vaugham (2005), the element of cognitive presence reflects the focus and success of the community of inquiry’s learning experience.  Participants in their study felt that it was easier to stay connected with others when using the online environment.  Since the sense of time was expanded when using the asynchronous online discussion area, it provided more opportunities for all to participate.  When they compared their study to others they noticed that teaching presence and social presence were connected.  They found that having a common or collaborative learning outcome may be essential.  So the idea of presence types seems to exist, but there needed to be a way to test it.                                                                                                 
         Arbaugh, Cleveland-Innes, Diaz, Garrison, Ice, Richardson, and Swan (2008) used a 34-item Community of Inquiry framework survey instrument during the summer of 2007 to test the validity of the CoI’s conceptual framework of Teaching, Social, and Cognitive Presences.  The results showed the CoI instrument to be a valid measure of the three types of presence.  A similar results was found by Arbaugh, Bangert and Cleveland-Innes (2010) who looked for significance regarding cognitive presence in different areas of classes.  Their findings suggest that the CoI framework may have more significance when using it with classes from the applied disciplines (Engineering, Nursing, Education) rather than classes from the pure disciplines (Natural Sciences, Humanities, Mathematics).  However, they also felt that social presence may not lend itself to the discipline-based differences as it depends more directly on the learners than do the other two presences.   
            Archibald (2010) also tested Garrison, Anderson and Archer’s Community of Inquiry Framework model by using undergraduate, graduate students and health professionals.  He created the Research Design Learning Resource (RDLR) which contained a collection of Canadian experts sharing their educational research stories, an online repository of resources about research design, and a discussion forum.  His findings were that approximately 69% of the variance in cognitive presence could be explained through the analysis of teaching and social presence.  This was true even when other factors, such as self-directed learning readiness, prior online learning experience, and prior collaborative learning experience, were taken into account.              
             Not everyone has agreed with the CoI model.  In the CoI model, it is felt that the learners themselves will decide what to focus on, working together to define their goals.  A 2010 study by Vlachopoulos and Cowan revealed findings that did not agree with the mainstream of thought.  They conducted tests in two universities, one English and one Scottish, using different types of blended sessions.  The sessions were designed to be student-centered and implicitly student-directed with tutors and e-moderators trained to allow students to take responsibility over their own learning.  Their results did not find that any negotiations were taking place between the tutors and learners as previous research has suggested (as cited in Anderson et al., 2001).  Instead, the tutor involved had greater influence over the learning than predicted.  These studies found that the e-moderators were deliberately trying to sway the discussions.     
           In a study by Kim, Kwon, and Cho (2011) instructors were trained to socially approach and interact with students during the classes using both one-way and two-way communications.  Their research found that although interactivity of the learners was a predictor of social presence, it was not a predictor of learning satisfaction, as suggested by the CoI model.     
           When understanding the role of social presence, it is necessary to look at the areas of course design, facilitation, and how it influences higher-order learning.  Members of a community need to understand what is expected of them in both the social and knowledge areas.  Establishing and helping learners maintain a community is often seen as the role of the facilitator with what is known as teaching presence and is the role of the instructor (Walton & Hepworth, 2011). 

Role of the Instructor

            The Community of Inquiry framework is a useful tool that helps us understand the teaching, social and cognitive presences.  The study by Garrison, Cleveland-Innes, and Fung (2010) emphasize the importance of teaching presence and its positive effect on the other types of presence.  But have other studies backed this idea?                                                       
            It has been found that in order to help students process individuating characteristics they need for social interaction with each other, instructors may be able to design interactions that allow participants to establish social behaviors (Slagter van Tryon & Bishop, 2009).  Hull, and Saxon (2009) examined the social interaction when controlling the instruction in two courses held at the same time.  The variations in instruction were in the areas of negotiation of meaning and co-construction of knowledge within these groups.  There was strong evidence to suggest that online learning groups were dependent on the facilitators to help students in asynchronous courses construct knowledge.  This was in direct disagreement with a study by Powell, Tindal and Millwood (2008) which did not find that the facilitator shaped the direction of the course.  Salmon (2000) seems to take a middle road by stating that while students can interact with course materials and other learners, they still have a need for an e-moderator.  
        Numerous studies found that students became frustrated when the lesson design   did not include clear instructions, concise objectives and general participation guidelines (Kupczynski, Ice, Wiesenmayer, & McCluskey, 2010; Powell, Tindal & Millwood, 2008; Salmon, 2000).  It was felt that when an instructor gives assignments it gives the students a shared mission that encourages them to stay on track and share more meaningful conversations (Dennen & Wieland, 2007).  In addition, the studies by Dzakira (2008), Dennen, Darabi, and Smith, (2007) and Schutt, Allen, and Laumakis (2009) all examined student response to their online classes.  These studies were interested in how the students perceive the classes.  All three found that students need a solid social presence from their instructors.  When comparing nineteen studies, Hiltz and Turoff (2002) found that whether or not students felt the online medium had resulted in better communication with their instructor than traditional methods, was one of the strongest influences of how students evaluated their courses.  In opposition to this, the findings of Marzelli and Dicker (2006) found that what online students missed most was the interaction with their instructor.  However, their article does not contain any statistics or methodology to verify this.  So it seems clear that instructors need to be involved within the community of learners and ensure that the objectives are clearly stated.

Conclusion

            Looking at the research that has been done, it seems to be generally accepted that students learn best when they perceive certain elements which are typically labeled as social, teaching and cognitive presences.  These three elements are interconnected in ways that affect how well students can learn.  In order for learning to take place in the online environment, it is believed that learners do best when they can form a community where they have a high level of trust and can share and explore different ideas (Learning Theories Knowledgebase, 2012; Garrison, Anderson & Archer, 2000; and Holmes and Gardner, 2006).  The presence of the teacher is felt to be necessary in order to help students accept and fit into the community and be guided to the overall goal.  When these two criteria are met, the community of learners can exchange ideas and learn from each other.  This constructivist approach will allow the learners to progress to a higher level of cognitive understanding of the information (McLeod, 2007).                                                    
       There are still areas to explore.  More needs to be known about the amount each of the presences truly plays in the real goal of learning.  How much the CoI framework applies to different disciplines of studies has only begun to be examined along with the ideas of reference points and teacher immediacy.  How is the construction of knowledge different for an individual as opposed to group learning?  What changes in the software would help facilitate instruction and what if the instruction includes other forms of media?  In looking at the literature, although some studies have been conducted using other cultures and comparing genders, almost every study has been performed at the college-age level so the results may not apply to younger students (Dzakiria, 2008).  So the research continues and our knowledge of this area grows.  However, for the research that has already been done, there are few resources for instructors to use.  Teachers new to the area of online mode of delivery would benefit from having access to the information in a more coherent and easy-to-use fashion.  Otherwise, all the information will remain unused by those whom it is supposed to benefit.
