Using Electronic Communication Tools in Online Group Activities to Develop Collaborative Learning Skills

The purpose of this study was to investigate the effect of using synchronous and asynchronous communication tools in online group activities to develop collaborative learning skills. An experimental study was implemented on a sample of faculty of education students in Mansoura University. The sample was divided into two groups, a group studied using synchronous communication tools, and the other group studied using asynchronous communication tools. The findings highlighted the fact that electronic communication tools have an effect to develop collaborative skills. However, the researchers found that the synchronous communication tools are more useful than asynchronous communication tools for developing collaborative learning skills in online group activities. The implications of the findings offer support for using synchronous communication tools in online group activities to develop collaborative skills.

Using Electronic Communication Tools in Online Group Activities to Develop Collaborative Learning Skills in the traditional way [9]. It offers learners the opportunity to study flexibly and it provides an opportunity to enroll on courses not available in their country [10]. Distance learning can be a lonely experience for students who may feel isolated and unsupported. However it is possible to use technology to motivate students to interact with each other and their tutors and work together towards common goals. It provides distance learners specifically with a sense of learning collaboratively within a community rather than on their own and therefore enables them to learn more effectively [11].

Collaborative Learning
Collaborative learning is defined as a pedagogy in which people come together in groups and learn from each other through cooperation [10]. Each student takes responsibility for the learning of other students in their group as well as their own and they help each other to be successful [12]. In collaborative learning, two or more learners are working together in a learning environment. Anuratha [13] has defined collaborative learning as the interdependence of the individuals as they share ideas and reach a conclusion or product. Collaboration among learners is seen as an important crux to learning where participants interact with each other and exchange ideas and share information with each other. Collaborative learning views knowledge as a social construct that stimulates active social interaction that could stimulate learning as learners work together independently and bring together their results into the final output.
Generally, learners will perform activities like asking questions, providing explanation and navigating the interaction that triggers learning. This will eventually generate both cognitive learning outcomes and social competency. Finally, collaborative learning found its way in the virtual world and created a new field in educational scenario that merges the notion of group-based learning and the potential of communication technology. Collaborative learning correlates to positive affective outcomes (e.g. [14], [15] such as higher motivation, higher self-esteem, more favorable attitude towards learning, and increased persistence. To be collaborative, learning groups must be carefully structured to include the five basic elements identified by Johnson, Johnson, & Smith [16]: (1) positive interdependence to ensure that students believe they "sink or swim together," (2) promotive interaction to ensure that students help and assist each other, (3) individual accountability to ensure that everyone does their fair share of the work, (4) social skills to work effectively with others, and (5) group processing to reflect on and improve the quality of group work.
Studies confirm that learners need to be trained to work collaboratively for their future careers [17], [18], In addition, collaboration is the key to a successful online learning is to develop a strong sense of community and collaboration among learners. collaboration is linked to learners' greater satisfaction with their academic program and to reduced feelings of isolation [19]. Mattehewsf & part (2003) reported that promote collaborative learning in distance programs, you will want to structure online group activities to encourage the kind of student interactions and active learning that foster deep learning. Online group activities should be planned and executed much like face-to-face activities -probably even more so for the asynchronous online classroom.

Online Group Activities
Group activities provide several important benefits in online teaching and learning environment as follows: [20].  Help participants discuss concepts that promote deeper understanding of the material.  Engage participants in the learning process and increase participation.  Allow participants to tackle more complex problems.  Give each participant experience in handling interpersonal processional relations, which is critical in "real-world" settings.  Provide or improve practice evaluation skills as working professionals.  Help create a sense of learning community, which is important for online students.  Allow group members to assess other members of the team as well as self-evaluation.  Assist participants to develop skills in independent judgments and encourage sense of involvement and responsibility on the part of students.  Provide data that might be used in assigning individuals grades for team assignments.  Improve learning and produce higher quality results.  Reduce instructors workload involved in assessing and grading.
message. You later read and respond to the message. There is a time lag between the time the learner sent the message and you replied, even if the lag time is short Asynchronous communication take place whenever learners have the time to complete them. For example, viewing videos linked to the course site, reading a textbook, and writing a paper are all asynchronous activities .In contrast, synchronous, or real-time, communication takes place like a conversation. If your class uses only writing-based tools to communicate, the only synchronous communication possible is a chat session. Everyone gets online in the same chat room and types questions, comments, and responses in real time. Synchronous activities may include chat sessions, whiteboard drawings, and other group interactive work. Ellis & Romano [8] suggested that Synchronous tools enable real-time communication and collaboration in a "same time-different place" mode. They reported that these tools allow people to connect at a single point in time, at the same time. Schwier & Balbar [27] pointed out that Synchronous tools possess the advantage of being able to engage people instantly and at the same point in time on the other hand Ellis & Romano [8] suggested that Asynchronous tools enable communication and collaboration over a period of time through a "different time-different place" mode. These tools allow people to connect together at each person's own convenience and own schedule.
Asynchronous communication and collaboration tools include e.g. E-mails, discussion forums, Wikis, Blogs, or Google Docs, these tools offer the opportunity for a single conversation to occur over days, weeks or even an entire term. Whereas, synchronous tools include e.g. chats, videoconferencing or Etherpad .These tools have become inexpensive to the point of nearly free to those with access to the required hardware (computer or mobile device with speakers, microphone and an optional video camera. Internet telephone offerings, such as Skype and Google Voice, offer free calls between accounts. Both also offer chat features that allow attendees without the required microphone to have a (written) voice in the conversation.
Both types of communication have their disadvantages, however. Disadvantages of synchronous communication include: getting students online at the same time, difficulty in moderating large-scale conversations, lack of reflection time for students, and intimidation of poor typists. Educators also cited the limitations of asynchronous communication: lack of immediate feedback, students not checking in of-ten enough, length of time necessary for discussion to mature, and students feeling a sense of social disconnection. On the other hand, disadvantages of asynchronous communication include: No real time discussions, live collaboration, Immediate feedback, or real time activities to increase motivation & engagement.
However, there is a lack on studies who suggested which type of communication tools is effective in online group activities to develop collaborative skills. Therefore our research will focus on this point .As a consequence an experimental study on the faculty of education students in Mansoura University was implemented to address the following question: What is the difference between the effect of using synchronous and asynchronous communication tools in online group activities to develop collaborative learning skills?

Research Methodology
In this section description for the research design, the participants of the study, learning environment and data collection and analysis is provided.

Research Design
As DiPetta [28] mentioned, "Experiences in virtual environments are like snowflakes-no two are alike" (p. 62). In this regard, the research purpose is to describe the effect of using synchronous and asynchronous communication tools in online group activities to develop collaborative skills. Thus, the design of two experimental groups was used, a group used synchronous communication tool, and another group used asynchronous communication tool

Participants
Participants belonged to one of two groups of learners. The learners had enrolled in a instructional design course available on Moodle in an instructional-technology professional diploma at Mansoura University in Egypt. Students were selected according to the purposive-sampling method. Group 1 consisted of 18 learners who were using synchronous communication tool (video call) in their online group activities of the course, and Group 2 consisted of 16 learners who were using asynchronous communication tool (wiki) in their online group activities of the course. Most of the learners had acquired little or no multimedia authoring knowledge before taking this class.

Learning Environment
In this study, synchronous communication tool (Skype) functioned as a supplemental tool for the first experimental group, it was the only tool that enables real-time and two-way oral and video communication among multiple participants. Participants in the chat room could communicate via text and oral conversation. Ten participants were already using skype so We instructed the rest of the participants to register a skype account for messenger installation. We did not adopt the chat tool that is available in MOOdle because it does not offer oral or video communication function. The group chat sessions constituted a forum where learners could discuss online group activities, and could respond to one another's 532 Using Electronic Communication Tools in Online Group Activities to Develop Collaborative Learning Skills questions. The other group Supplemented with as asynchronous communication tool (wiki), it was the only tool available for participants to discuss their online group activities, and communicated with each other. We instructed all participants of the second group to register a Wikipedia account because none of them has an account there. Each group of learners received the same instruction as did the other group. The only difference was that one group participated in only group activities using synchronous tool (skype) and the other online group participated in online group activities using asynchronous communication tool (wiki) . In both groups, every learner was assigned to participate in online group activities so that the pair could develop collaborative learning skills . As the present study reflects our effort to develop collaborative learning skills. A checklist of collaborative learning skills was designed for this purpose (appendix 1). It consists of 44 items .the checklist was applied on the learners of the two groups after and before using the communication tools (synchronous and asynchronous). we expected that the two groups of learners would demonstrate similar developing of collaborative learning skills.

Data Collection and Analysis
Checklist of collaborative learning skills Scale is the instrument that helps assess both learners' developing of collaborative learning, as we mentioned earlier. The Checklist contains of 44 statements, and applied it on participants of the two groups, after using the communication tools (synchronous and asynchronous) to do their online group activities at the end of the studying the course. the items ranking was from 1 to 7. (1) for strongly disagree and (7) for strongly agree. The total scores ranged from 0 to 308. We conducted Mann-Whitney U Test to determine whether or not there was a significant difference between collaborative learning skills of the two groups.

Results
To answer the research question: What is the difference between the effect of using synchronous and asynchronous communication tools in online group activities to develop collaborative learning skills?
We conducted an independent samples Mann-Whitney U Test to compare the degrees of collaborative learning skills checklist of the first group that used asynchronous communication tools with the degrees of collaborative learning skills checklist of the second group that used synchronous communications tools . Table 1 summarizes general descriptive statistics .The data in Table 1 indicate a significant difference between the first group that used asynchronous communication tools and second group that used synchronous communication tools. Asynchronous group score Asynchronous group score Z = 4.55. A significant difference was found between asynchronous group grades and synchronous grades for the group that used asynchronous communication tools. The results suggest that developing collaborative learning skills was stronger in the group that used asynchronous communication tools than the group that used synchronous communication tools in online group activities.

Discussion
The primary aim of this study was to investigate the difference between the effect of using synchronous and asynchronous communication tools in online group activities to develop collaborative learning skills. The literature-review section suggests that, using electronic communication tools (synchronous and asynchronous) develop collaborative learning skills. However, there is a lack of studies that suggested which type of communication tools is effective in online group activities to develop collaborative skills. Therefore our research work addressed this point. This study's collection and analysis of the data yield answers the research question ." What is the difference between the effect of using synchronous and asynchronous communication tools in online group activities to develop collaborative learning skills?" The Mann-Whitney U Test in table (1) indicates that using electronic communication tools develop collaborative skills. However, asynchronous communication tools had a stronger effect on developing collaborative learning skills than synchronous communication tool. The use of synchronous communication tool (skype) in online group activities did not develop collaborative learning skills similar to asynchronous communication tool (wiki) that of Using synchronous communication tool (skype) enabled the learners to accomplish tasks and participate in online group activities almost immediately This immediacy gave learners the impression, also, that they were attending a class similar to a regular class. However, during the first few sessions of the course when learners participated in their online group activities to discussed with each other the importance of multimedia-program production, the instructional design process, and evaluations of one another production of learning objects, there is a big chaos during their chatting with each other although not all students could participate in the same time. Moreover there is less time to think about what they want to say or their response to another; time may be a limiting factor. In addition, communication was so difficult because of the speed of data transaction with slower connections, Lack of reflection between collaborators If technology fails the collaboration session not possible, large time commitment for collaborators. Finally, lack documentation.
On the other hand, using asynchronous communication tool (wiki) in their online group activity was more appropriate to develop their collaborative learning skills. Participants could work with each other in more organized way. Participants of the group activities could to add, modify and post They could see and make changes to the document of the activity in real-time in a web browser, the ability to comment either on the document as a whole or on specific passages facilitate collaboration. Discussions and comments could be marked "resolved" to indicate group consensus. Asynchronous tool (wiki) possessed the advantage of being able to involve people from multiple time zones. In contrast of synchronous tool (skype), more time was allowed for responses which often-times results in enriched critical thinking and quality responses. Content can be accessed at any time within the context that comfortably suits them. In addition, asynchronous was helpful in capturing the history of the interactions of a group, allowing for collective knowledge to be more easily shared and distributed. In Conclusion, asynchronous tool was ideal for most collaborative writing and editing group activities.
(Christopher Machielse, 2011). It promoted group work, peer editing skills and multiple revisions.

Conclusions
Because collaborative learning skills is seen as an important crux to learning where participants interact with each other and exchange ideas and share information with each other, it is important to develop these skills. Using electronic communication tools is a useful practice for the development of higher order thinking skills, learner centered pedagogy, active and authentic learning, associative thinking, and collaborative learning skills.
