Review of a DE technology.

  1. 1. Assignment 6 Report of the Sultan Qaboos University College of education Presentation ILT Department Tech4010 Done By : Murtadha ALAjmi Hussain Al-Ajmi Submitted to : Dr. Alaa Sadik
  2. 2. Virtual Classroom Definitions Actually, there are various definitions to explain the meaning of Virtual classroom as follows:  A teaching and learning environment located within a computer- mediated communication system.  All activities and interactions take place through the computer instead of face-to-face.  Virtual education refers to instruction in a learning environment where teacher and student are separated by time or space, or both, and the ...  The online learning space where students and instructors interact.  The electronic, learning community where students and teaching faculty interact using Internet listservs and the World Wide Web. Features  Virtual classrooms provide the community and control some learners need.  Flexible time: students may participate at any time of the day... (Learning is flexible).  Efficient learning  Location: students are not limited to courses offered in their geographic locality.( Overcome distances)
  3. 3.  More active learning: the computer forces response and attention.  A Virtual Classroom might contain:  Class activities  Group and individual learning activities  Discussions and chats with students, parents and guests  Quizzes and surveys  Homework activities and assessment documents  Full online courses with modules of work  Forums and synchronous chat sessions WebQuests, Hotlists, Scavenger Hunts, etc. Features Analysis Synchronous √ Time of interaction Asynchronous √ Student-student √ Student-teacher √ Type of interaction Student-content √ Student-machine √ Group-based √ Learning style Self-based learning √ Flexibility Anytime √
  4. 4. Anyplace √ Ease of access/use √ Development √ Speed Feedback √ Delivery √ Stand-alone medium √ Instruction Multimedia support √ Cost √ Advantages Advantages for students  Virtual classrooms remove the need to travel to a location in which to participate in the course or lessons.  Virtual classrooms can be accessed from any computer that has the necessary software, hardware, Internet connection, and Internet browser requirements in order to participate in the virtual classroom.  Virtual classrooms are accessible to students with physical disabilities, which is an advantage over the real classroom, as they can access it from home.  Virtual classrooms have been affirmed as “time independent� meaning that students can access the course material and activities in the virtual classroom at a time that is most convenient to them.
  5. 5. Advantages for teacher  The teacher is not required to work from an office or classroom to instruct lessons or organize material and lessons; this can be done from anywhere where they have access to a computer with an Internet connection and other necessary software/hardware, which is an advantage.  Electronic content can be updated more efficiently than printed material, and at a lower cost, which saves the teacher time and money when preparing and adjusting material to suit their lessons and courses within their virtual classroom. Advantages for Schools and Businesses operating Virtual Classroom  For educational institutions and businesses offering courses, lessons, and/or training through virtual classrooms, several advantages exist over the traditional form of delivering courses and training in a physical classroom. One source says that technology-delivered training costs is less than half that of lecture/laboratory training costs, which is an advantage to educational institutions and businesses who want to create a means of educating people in a cost-effective format. Also, because training hours are usually less in a virtual classroom compared with a traditional classroom, they are an advantage to educational institutions as they would be paying teachers less because teachers would be working fewer hours to conduct lessons in the virtual classroom.
  6. 6. Limitations Limitations for students  Limited offerings: the choice of courses is limited at present.  Equipment requirements: students who do not have a computer will have to travel to use the necessary equipment.  Delayed feedback: it may be hours until a question is answered by the teacher. Limitations for teacher  The teacher must develop educational content that is interesting, relevant and important to students, and in an appropriate format (using asynchronous communication or synchronous communication tools), which is a difficult task. Example of Implementations of VC  Second Life has recently become a virtual classroom for major colleges and universities.
  7. 7. Cisco webex: provides on-demand collaboration, online meeting, web conferencing and video conferencing applications. Its products include Meeting Center, Training Center, Event Center, Support Center, Sales Center, MeetMeNow, PCNow, WebEx AIM Pro Business Edition, WebEx WebOffice, WebEx Connect, and others. Centra Click-to-Meet Horizon Wimba ILinc Macromedia Breeze Marratech Microsoft Live Meeting Concerns Select a qualified instructor. Provide complete instruction. Simplify tasks for learners. Manage teams and deal with problem learners. Enable interpersonal communication. Pick tools to suit learners:  Language fluency.
  8. 8.  Accents.  Typing skills.  Technical expertise. Communication and Interaction in Virtual Classroom Students in virtual education typically acquire knowledge in a uni-directional manner first (e.g. by studying a video, reading a textbook chapter). Electronic media like a discussion forum, chat room, voice mail, e-mail, etc. are often employed for communication. Homework assignments are normally submitted electronically, e.g. as an attachment to an e- mail. When help is needed, lecturers, tutors, or fellow students, or a help desk are available, just like in a real university. The difference is that all communication goes via electronic media. Synchronous Communication Synchronous Communication Tools Chat is “an online, real-time interactive communication method using text to send and receive instant messages? (World Wide Learn, 2005). It is commonly recognised as text-to-text communication that occurs between two or more people using the chat program, for example Microsoft’s Messenger Network (MSN). In comparison, videoconferencing allows the transfer of aural and visual communication over the Internet, thus communication occurs without text.
  9. 9. Teleconferencing is much the same in that it does not involve textual communication; it occurs over the Internet, but is also possible over other “telecommunication channels such as telephone lines, [and] local area networks? Both of these forms are most alike to face-to-face communication. In virtual classrooms, synchronous communication is used for learning and teaching, it has been referred to as a “channel? Of communication, which learners use to communicate with fellow class members and their teacher. Chat can occur between the teacher and the learner in real-time; hence replies are immediate, which is an attribute similar to face-to-face conversation in the traditional, physical classroom. Chat sessions are usually organised with a predetermined purpose that is in line with other learning activities in the virtual classroom. The way that chat is used can vary. For example, the discussion topic, level of engagement, and whether the communication is formal or non formal, and what the aim of the chat session is, all vary among different virtual classrooms. Videoconferencing and teleconferencing in virtual classrooms are not as common as chat tools, because they require “a minimum connection speed? As they are “memory-intensive; all students may not have these requirements. Asynchronous Communication Asynchronous Communication Tools E-mail is an asynchronous communication tool; the sender and receiver do not have to be in the same space as each other, or sending/receiving at the same time as each other. Listservs are an “automatic e-mail service? That sends e-mails that can be read by the recipient at any time. Listserv e-mails cannot usually be replied to, and are only sent to subscribers (World Wide Learn, 2005). These are common on websites that send out weekly newsletters or advertisements; they are

These pages can be read and commented on by others at any time, by accessing the web page that the weblog is contained on, for example Blogger is a service where people can create and view weblogs. Threaded discussions are an asynchronous communication tool; they are based on a topic that is discussed by a group of people, who contribute at different times. Asynchronous Communication and the Virtual Classroom In many virtual classrooms, “the instruction is delivered at one time and the work can be done at a different time? (Oregon Network Education, date unknown). In this case, learning is self-directed, and asynchronous communication tools are used. Asynchronous tools used in the virtual classroom allow students to participate in various class activities, discussions, and other online interactions with their teacher and fellow class members, at their own pace and in their own time (World Wide Learn, 2005; Watkins, 2004). Both the teacher and the student benefit from asynchronous communication forms, such as discussion groups and forums, because the “entire discussion is recorded? Points can be revised any time after or even during a discussion. Case Study There was researcher in USA called Dana Parrish. He conducted in 2005 the most used Virtual classroom tools to find out the first three tools by doing questionnaire/survey. The tested tools were as follows: - Centra - Click-to-Meet
  11. 11. - Horizon Wimba - iLinc - Macromedia Breeze - Marratech - Microsoft Live Meeting - WebEx The researcher had found out that Horizon Wimba, iLinc, and Microsoft Live Meeting are the most attractive and implemented tools of virtual classroom through internet in USA. Dana Parrish References"
