  • eClassrooms Come of Age?

    1. 1. eTeaching Have eClassrooms come of age? Project Leader Alan Wimberley Team Marg Knight Mark Tasman
    2. 2. Introduction <ul><li>Have online classrooms come of age? How far can we push them given current network infrastructures? </li></ul><ul><li>We compare some eClassroom products, share the experience of working with two of them, and look at high-end technologies that will become generally available in the near future. </li></ul>
    3. 3. Project Summary <ul><li>Investigate and evaluate emerging IP collaborative technologies with particular reference to IP Video Conferencing. </li></ul><ul><li>Use the blended distance learning option of the Cisco Networking Academy Program as a vehicle for the investigation </li></ul>
    4. 4. Technologies <ul><li>On-line classroom </li></ul><ul><li>Wikis </li></ul><ul><li>Blogs </li></ul><ul><li>The Cisco Networking Academy Management System (CNAMS) </li></ul><ul><li>Packet Tracer 5 (Cisco product) </li></ul><ul><li>Netlab </li></ul>

    6. 6. Choice of eClassroom service <ul><li>We used Connect Pro and Webex </li></ul><ul><li>A Webex account was provided to us by the Cisco Learning Institute </li></ul><ul><li>We purchased a year's licence for the US hosted Connect Pro </li></ul><ul><li>(Later trialled locally hosted version) </li></ul>
    7. 7. ConnectPro Screenshot
    8. 8. Webex Screenshot
    9. 9. How did they perform? Voice, video, whiteboard, presentations, application sharing, polling, chat, file sharing, interactivity
    10. 10. Voice <ul><li>Participants found voice quality to be generally acceptable, even though there were dropouts, and some voice distortion. </li></ul><ul><li>Webex was the best for voice, closely followed by the locally hosted Connect Pro. </li></ul>
    11. 11. Voice <ul><li>If all participants microphones are on, this is likely to cause a lot of noise. If the participant is not using a headset, then their speaker can feedback unpleasantly. </li></ul><ul><li>Turn off all microphones, and give the microphone to participants as required. </li></ul>
    12. 12. Video <ul><li>As can be seen, video does work. </li></ul><ul><li>However, it is very small, has a low frame rate, and does not synch with voice. </li></ul><ul><li>Freezing the video gave some impression of attendance. </li></ul>
    13. 13. Video <ul><li>Video was generally unsatisfactory. </li></ul><ul><li>With Connect Pro, the more video participants, the smaller the images, until the images were off-screen. </li></ul><ul><li>With Webex it was difficult to display video and chat/participants screens </li></ul><ul><li>Best use was to start the video in Connect Pro, and freeze the image. </li></ul>
    14. 14. Whiteboard <ul><li>Whiteboards are disappointing, and do not provide ease of use. </li></ul><ul><li>In Connect Pro, students could wipe the whiteboard if given minimum permission to draw on it. </li></ul><ul><li>Webex allowed students to erase their own drawings only </li></ul>
    15. 15. Presentations
    16. 16. Presentations <ul><li>Both Connect Pro and Webex change powerpoint presentations to their own format. </li></ul><ul><li>Both perform well for slide shows. </li></ul>
    17. 17. Application Sharing
    18. 18. Application sharing <ul><li>Some applications, when shared, chew through bandwidth </li></ul><ul><ul><li>e.g. Word, Exel </li></ul></ul><ul><li>This causes glitches in voice </li></ul><ul><li>Do not talk while manipulating shared applications </li></ul>
    19. 19. Application Sharing <ul><li>Connect Pro provides a preview screen of what participants are seeing - second screen is ideal for this. </li></ul>
    20. 20. Polling <ul><li>Connect Pro will do only one poll question at a time when using the &quot;poll pod&quot; on the fly. </li></ul><ul><li>Webex allows more than one question at a time on the fly </li></ul>
    21. 21. CHAT Chat was used from the start of a session to the end. At the beginning and end of a session, attendees chatted to each other and the presenters. During a session, chat was used by presenters to ask questions.
    22. 22. Chat <ul><li>Chat works well. </li></ul><ul><li>Participants can chat to each other, with presenters or hosts, and can do so privately or publicly </li></ul>
    23. 23. File Sharing <ul><li>Large files downloaded by multiple users simultaneously will result in deterioration of voice. </li></ul><ul><li>File sharing is best done before or after presentations, not during </li></ul>
    24. 24. Icons (Emoticons) <ul><li>&quot;Participant status&quot; </li></ul><ul><li>All participants can bring up their choice of available icons beside their name in the participant's list. </li></ul><ul><li>Icons include </li></ul><ul><ul><li>hand up </li></ul></ul><ul><ul><li>smiley </li></ul></ul><ul><ul><li>go faster </li></ul></ul>
    25. 25. Connection Monitor Connect Pro provides some connection information as shown on the left. These data were captured with the classroom open, but no participants
    26. 26. What worked <ul><li>Powerpoint presentations </li></ul><ul><li>Voice </li></ul><ul><li>Netlab with voice </li></ul><ul><li>Polls </li></ul><ul><li>Chat </li></ul><ul><li>Using icons </li></ul>
    27. 27. What didn't work <ul><li>Showing videos </li></ul><ul><li>Netlab running at the same time as a slideshow caused problems. </li></ul><ul><li>Videoconferencing </li></ul><ul><li>Whiteboard for much more than text </li></ul>
    28. 28. Recommendations
    29. 29. Run trial sessions until confident. <ul><li>You will need to consider </li></ul><ul><ul><li>Uploading powerpoint files before sessions - large files can take several minutes </li></ul></ul><ul><ul><li>Have poll questions ready beforehand - you will be busy enough running the session without creating them on the fly </li></ul></ul><ul><ul><li>Have applications running on your workstation ready to share </li></ul></ul>
    30. 30. Sort participant issues with pre-sessions. <ul><li>Participants may : </li></ul><ul><ul><li>require to download software to access the eclassroom for the first time </li></ul></ul><ul><ul><li>have issues with voice </li></ul></ul><ul><ul><li>have issues with video </li></ul></ul><ul><ul><li>not understand how to use icons or chat </li></ul></ul><ul><li>Try to sort these issues with &quot;orientation&quot; sessions </li></ul>
    31. 31. Have two presenters <ul><li>The main presenter will run the class - showing powerpoint or sharing application. </li></ul><ul><li>The second presenter is free to respond to chat questions, deal with participant issues. </li></ul><ul><li>On more than one occasion, the second presenter took over when the main presenter's voice was not working. </li></ul>
    32. 32. Have a second screen <ul><li>A second screen provides more screen &quot;real estate.&quot; </li></ul><ul><li>Use for preview </li></ul><ul><li>Have a script on the first screen </li></ul>
    33. 33. Use icons, polls and chat to maintain participant involvement. <ul><li>Voice, chat, icons and polls are the mainstay of an eClassroom. </li></ul>
    34. 34. Other technologies Wikis Blogs
    35. 35. Wiki <ul><li>Choice of Wiki is </li></ul><ul><li>No adverts !! Free !!! </li></ul><ul><li>There is a private Wiki for all students and staff in the project. All are invited to contribute to it. </li></ul><ul><li>Students also have to complete a case study for Cisco, and will create their own private team Wikis </li></ul>
    36. 36. Blog <ul><li>Choice of Blog site is </li></ul><ul><li>No adverts !! Free !!! </li></ul><ul><li>Academy students are required to keep a journal. For this project, they will write their journals as a blog </li></ul>
    37. 37. Cisco Specific
    38. 38. CNAMS
    39. 39. Packet Tracer 5 <ul><li>Packet Tracer is software for Academy students which emulates networks and network devices. </li></ul><ul><li>PT5 will allow connectivity of student created networks over an intranet (local,) or the Internet (global.) </li></ul>
