[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],V-Room (dependent) (independent) Real  presence with mWBT
Scenario: Virtual Room LIT HighTech – bought - HR - point2point = group 2 group-connection –  Special room for teacher/special room for learner - centralised
Scenario: Virtual Room D LowTech – rented - LR - multipoint = person 2 person 2 group –  No special room for teacher neither for learner - decentralised
Experience with TraiNex/AdobeConnect: 3,500 teaching-hours per year,  70,000 learner-hours per year  1/3 of the workload of part-time-students  Typical:  One teacher and 20 students join the room  via web and their campus-login at 6 pm,  2 hours of presentation,  1 hour of practice and discussion.
Chat, for  written  questions  VIDEO-area, eye-catcher, but not important Slides (Powerpoint), shown by the teacher Alternative: An application or a screen  of the teacher or of the student is broadcasted List of real names of the  participants  Agenda or  quick poll
First 5 minutes: free chat and warm-up „where are you?“
Teacher shows agenda or shows an actual example and  speaks about it. Aim: Motivation
Teachers shows slides and explains them auditively
Student shows slides and explains them auditively
Writing on a board and calculating together  BTW: Teacher sits in a hotel near the beach  
Exam: a student and one teacher are in one real room  and a second teacher is in a different place (BTW: 6 hours less traveling-time for me)  student  presents  slides
After  30 minutes it‘s time for questions  Exam: a student and one teacher are in one real room  and a second teacher is in a different place (BTW: 6 hours less traveling-time for me)
Exam: a student is in one real room (Hong-Kong)  and two teachers are in a different place in Germany BTW: dangerous scenario, because you can‘t control the student.
Virtual Room 100 students need 100 PCs and 100 cable / Multipoint connections /  e.g. Adobe Connect (100 students need 2 PC plus 1 cable) Point 2 Point connection, e.g. Tandberg Recording of the live-session results  (quick and dirty)  in web-based-training-material (many to many): decentralised (many to 1)  to (1 to many): centralised    (can be „limited“ to a centralised solution?)    (can be extended to decentralised solution?)

Hinweis der Redaktion

  1. E-Learning in the wider sense of the word: studying with electronic aids E-Learning in the narrow sense of the word: studying, independent of time and independent of space Nowadays the bandwith is getting good and the dependence on space is getting lower and lower, even for LR-Videoconferencing.
  2. Though it is called „video conference“ the video pod is not important. It is sometimes nice to see the others, but it is not needed for the lecture. More important is the broadcast of the voice and the broadcast of the slides.
