2.
Aims of session <ul><li>Some types of technology </li></ul><ul><li>Some uses of videoconferencing </li></ul><ul><li>Some issues in implementation </li></ul>

3.
The ANNIE project <ul><li>Providing access to remote experts/ remote delivery to students </li></ul><ul><li>Using various technologies </li></ul><ul><li>in various teaching situations </li></ul><ul><li>supporting drama, dance and theatre studies </li></ul>

4.
Various technologies <ul><li>ISDN </li></ul><ul><li>IP ViewStation </li></ul><ul><li>IP + PC </li></ul><ul><li>IP + PC + projection </li></ul><ul><li>Two-way </li></ul><ul><li>Multi-way </li></ul>

5.
ISDN sessions <ul><li>High quality video BUT </li></ul><ul><ul><li>Requires a lot of organising </li></ul></ul><ul><ul><li>Unreliable </li></ul></ul><ul><ul><li>In rooms unsuitable for teaching </li></ul></ul><ul><ul><li>Couldn’t run PowerPoint </li></ul></ul><ul><ul><li>Technology not “owned” </li></ul></ul><ul><ul><li>Expensive </li></ul></ul>

6.
IP + PCs + projection <ul><li>weaknesses </li></ul><ul><li>Low quality </li></ul><ul><li>Bandwidth problems </li></ul><ul><li>Required some upskilling at far end </li></ul><ul><li>Permissions through firewalls </li></ul>

7.
IP + PCs + projection <ul><li>strengths </li></ul><ul><li>Some preferred low quality of IP </li></ul><ul><li>Felt empowered by: </li></ul><ul><ul><ul><li>familiar technology </li></ul></ul></ul><ul><ul><ul><li>Location of technology </li></ul></ul></ul><ul><ul><ul><li>Ease of use </li></ul></ul></ul><ul><li>Low or no cost </li></ul>

8.
ISDN v IP <ul><li>ISDN no bandwidth problems </li></ul><ul><li>IP no location or booking problems </li></ul><ul><li>Depends on which technology other end has access to or wants to use </li></ul><ul><li>Can mix and match using JVCS </li></ul>

9.
Room-based TCP/IP <ul><li>Had success with Polycom ViewStation </li></ul><ul><li>Plug-and-play: just connected to Internet port in studio </li></ul><ul><li>High quality video and audio </li></ul><ul><li>BUT firewall and bandwidth problems, could only use in evenings </li></ul>

10.
Room-based TCP/IP <ul><li>Some institutions connected to Access Grid </li></ul><ul><li>Dedicated location means less likely to have a firewall problem </li></ul><ul><li>High quality video and audio </li></ul><ul><li>BUT only 1500 institutions connected across world </li></ul>

11.
Tutorials and vivas <ul><li>For tutorials </li></ul><ul><li>just need a PC, a headset, and a webcamera </li></ul><ul><li>Typified by high amounts of interaction between students and lecturers. </li></ul><ul><li>Virtual scenography. </li></ul>

12.
Lectures and software demos <ul><li>For lectures </li></ul><ul><li>also need a data projector, speakers, a digital video camera and a videobus </li></ul><ul><li>One mode (lecturer to student) tends to dominate </li></ul><ul><ul><li>Stage design software </li></ul></ul>

13.
Videoconferenced workshops <ul><li>Linking two sites </li></ul><ul><ul><li>Physical Performance </li></ul></ul><ul><li>Linking multiple sites </li></ul><ul><ul><li>Telematic Performance at Warwick </li></ul></ul>

14.
Other synchronous work <ul><li>Text chat </li></ul><ul><li>Audio chat </li></ul><ul><li>Telephone </li></ul><ul><li>SMS messaging </li></ul><ul><li>Above in combination </li></ul><ul><li>http://www.upstage.org.nz/ </li></ul>

15.
Implementation <ul><li>Strengths </li></ul><ul><li>Had involvement of a specific school </li></ul><ul><li>Academics set agenda </li></ul><ul><li>Few changes in working practices </li></ul><ul><li>Provided a manageable and easily implemented technology </li></ul>

16.
Implementation <ul><li>Weaknesses </li></ul><ul><li>Central services gatekeepers but not stakeholders </li></ul><ul><li>No in-house technical support to continue work </li></ul>

17.
Recommendations <ul><li>Inform participants of techniques for effective videoconferenced teaching </li></ul><ul><li>Devolve as much of the technology skills as possible </li></ul><ul><li>Be flexible with technology and activities </li></ul><ul><li>Manage expectations </li></ul><ul><li>Promote internally </li></ul>
