Teaching via videoconferencing Mark Childs Cat Fergusson Christine Smith
Aims of session • Introduction to the types of technology on offer • outline of some of the issues involved in conducting tutorials and lectures via videoconferencing • details concerning planning and setting up a videoconference
Teaching via videoconferencing • 1. Introduction • 2. The ANNIE project • 3. Technologies at Warwick
Teaching via videoconferencing • 4. Tutorials • 5. Lectures • 6. setting up a videoconference
Teaching via videoconferencing • 7. contacts • 8. specific technical points • 9. terminology
1. Introduction • experiences • plans • questions
2. The ANNIE project • Providing access to remote experts/ remote delivery to students • using various technologies • in various teaching situations • supporting drama, dance and theatre studies
The ANNIE project First Year: • Students and staff at Warwick, Kent, De Montfort and Exeter universities • Also involving lecturers from BBC, Kansas University, TechBC Second year: further dissemination
3. Various technologies Advantages and disadvantages • ISDN • ISDN at Warwick • IP ViewStation • IP at Warwick • IP + PC + projection
Advantages standard technology provides dedicated high bandwidth ISDN videoconference Disadvantage • facilities at Warwick, unsuitable, unreliable, expensive (for teaching)
Advantages plugs into any network port plug-and-play Disadvantage requires high bandwidth (at least 0.5 Mbps) IP-based videoconferencing
Using IP + PC-based conferencing For tutorials • just need a PC, a headset, and a webcamera For lectures • also need a data projector, speakers, a digital video camera and a videobus
IP + PCs + projection Weaknesses • low quality • bandwidth problems • may require some support at far end • permissions through firewalls
IP + PCs + projection Strengths • some preferred low quality of IP • felt empowered by: • familiar technology • location of technology • ease of use • low or no cost
4. Tutorials Not problematic pedagogically • communication modes one-to-one, -two -three • interactive • student-centred • focused on shared documents
Communication style • Hand-over between speakers difficult due to time lag • slower and clearer interactions • if breakdown in communication - stop and clarify before moving on • monitor outgoing image
Other things that can help • Shared props - handouts, documents • media files • “dress rehearsal”
Using NetMeeting • Chat • whiteboard • desktop sharing • file transfer
5. Lectures Require more modification • many-to-one communication • students not as participatory • more difficult for participants to be attentive for long periods
Modifying lectures Structure • break into short sections • have non-videoconference-based activities for students to do • frequently and formally elicit feedback • if possible have facilitator at other end
6. Setting up a videoconference • Numbers; IP, telephone, ISDN • times • who's contacting whom • software versions • distribute documents
7. Contacts • m.childs@warwick.ac.uk • audio-visual@warwick.ac.uk • http://www.warwick.ac.uk/services/its/ services/audiovisual/bookvconf.html • http://www.ukc.ac.uk/sdfva/ANNIE/ie/
8. Technical points • Echo • sightlines • firewalls • USB and parallel ports
9. Terminology • Bridge • bit rate/ baud rate • typical bandwidths
