Zitterbart {sturze|eggers|zit}@ibr.cs.tu-bs.de Institute of Operating Systems and Computer Networks Technical University Braunschweig, Germany Outline 1. Introduction 2. Objectives 3. Methods 4. Observations 5. Conclusions

2. D. Sturzebecher, Institute of Operating Systems and Computer Networks, TU-Braunschweig Introduction n why tele-teaching ? competence sharing geographical separation company training lifelong learning n requirements synchronous collaboration –whiteboard: black-board, overhead, projector, tele-pointer,... –audio/video –special shared tools asynchronous collaboration –learning environment  support for interactivity

3. D. Sturzebecher, Institute of Operating Systems and Computer Networks, TU-Braunschweig Objectives n substitution of traditional tools for digital transmission black-board, overhead, projector, pointer,...  whiteboard n improve existing systems by providing extended drawing capabilities object manipulation capabilities support multiple pointers (tele-pointer, marker) n support floor-control

4. D. Sturzebecher, Institute of Operating Systems and Computer Networks, TU-Braunschweig IBR-Whiteboard based on Internet technologies Java based, platform independent easy to use graphical user interface presentation of slides provides tele-pointer and access control improved cut and paste integrated in MBone tools

5. D. Sturzebecher, Institute of Operating Systems and Computer Networks, TU-Braunschweig Methods n hands-on experience during lectures n lecture in 97 with MBone tools “monitoring” of selected participants no empirical evaluation –small sample size –no short-range comparison of local and remote learning results  good impression on technical short comings  technical assistant required

6. D. Sturzebecher, Institute of Operating Systems and Computer Networks, TU-Braunschweig n lecture in 98 with advanced whiteboard local and remote students remote lecturer embedded in “larger” project including evaluation by project members from didactic and education institutes –design of user interface –questionnaires  evaluation currently ongoing, results not yet available

7. D. Sturzebecher, Institute of Operating Systems and Computer Networks, TU-Braunschweig Lecture Setup beamer auto-tracking camera screen and mouse for whiteboard projection area computer with internet connection

8. D. Sturzebecher, Institute of Operating Systems and Computer Networks, TU-Braunschweig Lecture Setup n separate notebook for whiteboard presentation n auto-tracking camera Internet beamer notebook workstation video remote access

9. D. Sturzebecher, Institute of Operating Systems and Computer Networks, TU-Braunschweig Conclusions n high complexity n teaching assistant required n technical experienced lecturers n further improvements in whiteboard n whiteboard is included in advanced interactive collaboration system developed at IBR n web-based learning environment as first prototype available n further evaluation during upcoming semester
